With the ever increasing use of wireless communication devices for accessing networks and downloading large files (e.g., video files), there is an increasing demand for radio frequency spectrum. Smart phone users complain about dropped calls, slow access to the Internet and similar problems which are due largely to too many devices trying to access finite RF bandwidth allocated to such services. Yet parts of the RF spectrum, such as the RF bands dedicated to emergency services (e.g., police, fire and rescue, etc.), go largely unused due to the non-continuous and episodic employment of such voice-radio communication bands. Therefore, improved methods and solutions for dynamically allocating underutilized telecommunication resources (e.g., RF spectrum, etc.) of a first telecommunication network for access and use by wireless devices that subscribe to other networks will be beneficial to the telecommunication networks, service providers, and to the consumers of telecommunication services.
The various embodiments include methods of performing dynamic spectrum arbitrage (DSA) operations that include determining in a processor of a dynamic spectrum policy controller (DPC) whether there is bandwidth available for allocation within cells serviced by the DSC in a first telecommunication network, generating a resource register request message that includes a data bandwidth information element that identifies an amount of bandwidth that is available for allocation and use by wireless devices in a second telecommunication network in response to determining that there is bandwidth available for allocation within cells serviced by the DSC, sending the generated resource register request message to the DPC, receiving a resource register response message from the DPC in response to sending the generated resource register request message, receiving a bid success message that includes information identifying the amount of the bandwidth that is requested by the second telecommunication network, and sending a resources allocated message to the DPC to commit the requested amount of bandwidth for access and use by wireless devices in the second telecommunication network.
In an embodiment, generating the resource register request message includes generating the resource register request message to include a time duration information element (IE) that includes information suitable for use in determining a time period during which the resources are to be made available. That is, the DSC may generate the resource register request message to include a time period value. In a further embodiment, generating the resource register request message may include generating the resource register request message to include a list of grids information element that includes information suitable for use in determining grid identifiers for the locations of the bandwidth that is to be made available.
In a further embodiment, the method may include monitoring a congestion state of a plurality of eNodeBs in the first telecommunication network, and determining whether there is bandwidth available for allocation within cells serviced by the DSC in a first telecommunication network may include determining whether there is bandwidth available for allocation within the cells based on the monitored congestion states of the eNodeBs. In a further embodiment, the method may include maintaining data context information by storing one of a bid state, a bid role a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid and cell identifier list, and a closed subscriber group identifier. In a further embodiment, the method may include receiving in a dynamic spectrum policy controller (DPC) processor the resource register request message, determining whether to accept the received register request message, and adding the amount of bandwidth identified in the data bandwidth information element to a pool of resources in response to determining to accept the register request message.
In a further embodiment, the method may include receiving in the DPC processor a resource bid from the second telecommunication network and a plurality of additional telecommunication networks (e.g., via DSCs). Each resource bid may include a bid amount and a requested amount of bandwidth. The method may further include determining that the bid amount in the resource bid received from the second telecommunication network is the highest bid for the requested amount of bandwidth, and generating the bid success message to include information identifying the requested amount of bandwidth identified in the resource bid received from the second telecommunication network.
In a further embodiment, the method may include storing data context information pertaining to an arbitrage process, registered DSCs, and bids in a memory of a dynamic spectrum policy controller (DPC). In a further embodiment, storing data context information includes storing one of a bid state, a bid role, a bid winners list, a bid winner, a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid and cell identifier list, and a closed subscriber group identifier.

References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the invention or the claims.
In overview, the various embodiments include a dynamic spectrum arbitrage (DSA) system that includes a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC). The DPC and DSC may be configured to dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DPC may store DSA context information related to a bid with a DSC list, a DSC role, a PLMN of the DSC, an IP address or realm of the DSC, a bid id list and for each bid, a bid state, a bid role, a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid and cell identifier list, and a closed subscriber group identifier. The DSC may store DSA context information related to bid with a bid state, a bid role a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid, and cell identifier list, and a closed subscriber group identifier.
In addition, the DSA system may also include a dynamic spectrum arbitrage application part (DSAAP) component. The DSAAP component may allow, facilitate, support, or augment communications between the DSC and DPC so as to improve the efficiency and speed of the DSA system and telecommunication network. For example, the DSAAP component may allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations. In addition, the DSAAP component may improve the DSA resource auctioning operations by improving the performance and efficiency of the procedures for bidding, generating invoices, advertizing resources, requesting resources, purchasing resources, validating bid credentials, etc.

The various embodiments include a dynamic spectrum arbitrage (DSA) system configured to dynamically manage the availability, allocation, access, and use of telecommunication resources, such as radio frequency (RF) spectrum and RF spectrum resources. The DSA system may include various DSA components, such as a dynamic spectrum policy controller (DPC) component and a dynamic spectrum controller (DSC) component. The DPC component may be configured to manage the DSA operations and interactions between two or more networks (e.g., between a lessor network and a lessee network), which often requires communicating with a DSC component in each of the participating networks. As part of these DSA operations, the DSA components (e.g., DPC, DSC, etc.) may be required to manage data contexts.
In addition to managing data contexts, the DSA components (e.g., DPC, DSC, etc.) may be required communicate frequently and/or transmit a large amount of information. As such, the communications, interactions, and communication interfaces between these components may have a significant negative impact on the efficiency and speed of the DSA system and the participating telecommunication networks.
The various embodiments include a dynamic spectrum arbitrage application part (DSAAP) protocol and component configured to allow, facilitate, support, or augment communications between the DSA components (e.g., DPC, DSC, eNodeB, etc.) so as to improve the efficiency and speed of the DSA system. In addition, the DSAAP protocol/component may be configured to allow the DSA components to communicate specific information and perform operations that together provide various DSA functions that improve the efficiency and speed of the DSA system and participating networks.
In various embodiments, all or portions of the DSAAP component may be included in a DPC component, a DSC component, an eNodeB component, in an independent DSA component, or any combination thereof. The DSAAP component may be implemented in hardware, software, or a combination of hardware and software. In an embodiment, the DSAAP component may be configured to implement a DSAAP protocol, which may be defined over the Xe, Xd, and/or X2 reference points. In various embodiments, the Xe reference point between DSC and eNodeB may use the DSAAP protocol, TR-069 protocol, and/or TR-192 data model extensions to support listing available resources at the eNodeB and notifying the eNodeB of bid/buy confirmations. The Xd reference point between DSC and DPC may use the DSAAP protocol for dynamic spectrum and resource arbitrage operations. The X2 interface/reference point between the eNodeBs may also use the DSAAP protocol to communicate information.
In various embodiments, the DSAAP component may be configured to allow an eNodeB to communicate with a DSC component (e.g., via the Xe interface), with other eNodeBs (e.g., via an X2 interface), and with various other components (e.g., via the S1 interface). By allowing the eNodeB to communicate efficiently with these components, the DSAAP component may further improves the efficiency and speed of the DSA system.
For example, in an embodiment, the DSA system may include an eNodeB that is equipped with a DSC application protocol and congestion monitoring (DAPCM) module. The DAPCM module may be configured to monitor various network conditions (e.g., network congestion, resource usage, resource availability, etc.), generate reports based on the monitoring, and send the generated reports to a DSC component via the DSAAP. The DSC may be configured to receive and use such information to make better or more informed resource requests and/or to better identify the resources that could be made available for allocation.
As another example, in an embodiment, the DSC may include an eNodeB geographic boundary management (EGBM) module configured to maintain records suitable for identifying geographical areas/boundaries associated with various resources. The EGBM may be configured to communicate (e.g., via the DSAAP) this information to the eNodeB, which may receive and use such information to make better and more efficient use of the allocated resources. For example, the eNodeB may use the geographical information received from the DSC to better determine the geographic regions (e.g., zones, cell sites, etc.) in which a wireless device may use an allocated resource. Such communications also allow the DSA system to better allocate resources to a targeted geographic area, and to better allocate resources per user, per sector, per base station, per cell cluster, per license area, etc.
In various embodiments, the DSAAP component may be configured to allow, facilitate, support, or augment communications between the DSC component and the DPC component so as to improve the efficiency and speed of the DSA system and telecommunication network. Such communications may allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations. Such communications may also improve the DSA resource auctioning operations by improving the performance and efficiency of the procedures for bidding, generating invoices, advertizing resources, requesting resources, purchasing resources, validating bid credentials, etc.
In the various embodiments, the DSAAP component(s) may allow the various DSA components (e.g., DSC, DPC, eNodeB, etc.) to communicate using the DSAAP protocol and to perform various DSAAP methods. For example, the DSAAP methods may be performed in a DSA system that includes a first DSC server in a first telecommunication network (e.g., a lessee network), a second DSC server in second telecommunication network (e.g., a lessor network), and a DPC server that is outside of the first and second telecommunication networks.
In various embodiments, the DSAAP component may be configured to facilitate, support, or improve the DSA operations for bidding, resources allocation, and billing. Such DSAAP/DSA operations may include receiving in a DSC processor a list of resources that are available for bidding (via a communication link to a DPC/DPC processor), generating bid request message (e.g., DSC Bid Request message) that includes information suitable for bidding on a resource identified in the received list of resources, and sending the generated bid request message to the DPC (via the communication link). The DSAAP/DSA operations may also include the DPC processing starting a timer, receiving the bid request message (e.g., DSC Bid Request) from the DSC via the communication link, determining whether the bid request message is valid, and sending a bid accept message (DSC Bid Accept) to the DSC in response to determining that the bid is valid. The DPC processor may then determine whether the bid timer has expired, determine whether the DSC is a winner bidder that is to be allocated the resource (i.e., based on information included in the bid request message) in response to determining that the bid request message is valid and that bid timer has expired. The DPC processor may send a bid won message to the DSC via the communication link in response to determining that the DSC is the winner bidder. The DPC processor may then allocate the resource from a lessor network for access and use by a lessee network associated with the DSC.
In an embodiment, the DSAAP/DSA operations may include receiving in the DPC processor usage parameters and payment instructions from a component in the lessor network, generating an invoice for the access and use of the allocated resource by the lessee network, and sending the generated invoice to the DSC. The DPC processor may send the payment instructions and an invoice for to the use of the allocated resource by the lessee network to the DSC via the communication link, receive payment information from the DSC, and use the received payment information to settle the invoice.
In an embodiment, the DSAAP/DSA operations may include resource registrations operations. For example, the DPC processor may be configured to receive a resource register request message (e.g., DSC Resource Registration Request) from a second DSC in a lessor network, use the information included in the received resource register request message to make a plurality of resources available for bidding or buying via a financial brokerage platform, and generate the list of resources to include the plurality of resources. The bid request message may include a bid identifier information element (IE) that identifies a specific resource for which the DSC bids, a network identifier IE that identifies a specific network that includes the resource for which the DSC bids, and a bid amount IE that identifies a monetary amount offered for the access and use of the resource for which the DSC bids. In an embodiment, determining whether the bid request message is valid may include determining whether the monetary amount offered for the access and use of the resource (i.e., in the bid request message) is equal to an asking price for that resources received from its corresponding lessor network.
In the various embodiments, the DSAAP component(s) may allow the various DSA components (e.g., DSC, DPC, eNodeB, etc.) to communicate using the DSAAP protocol and to perform various DSAAP methods. For example, the DSAAP methods may be performed in a DSA system that includes a first DSC server in a first telecommunication network (e.g., a lessee network), a second DSC server in second telecommunication network (e.g., a lessor network), and a DPC server that is outside of the first and second telecommunication networks
The first DSC may include first DSC processor that is coupled to the DPC via a first communication link (i.e., a wired or wireless link), and the second DSC may include a second DSC processor coupled to the DPC via a second communication link. In addition, each of the first and second DSCs may be coupled to an eNodeB. For example, the second DSC may be coupled to an eNodeB in the second telecommunication network via third communication link. The first and second communication links may be defined over the Xd interface, and the third communication link may be defined over the Xe interface. That is, the DSCs may communicate with the DPC via the Xd interface by using the DSAAP protocol, and the DSCs may communicate with the eNodeBs in their respective networks via the Xe interface by using the DSAAP protocol.
In an embodiment, the eNodeB processor may be configured to monitor network conditions, generate reports based on a result of the monitoring, and send the generated reports to the second DSC via the third communication link. This may be accomplished by using the DSAAP protocol (i.e., by sending/receiving DSAAP communication messages and/or performing any of DSAAP methods discussed in this application). In an embodiment, monitoring network conditions may include monitoring one of network congestion, resource usage, and resource availability in the second telecommunication network.
In the various embodiments, a DSC processor may be configured to manage resource arbitration within a PLMN. The DSC processor may be configured to maintain network resource listings, and information for current bids, in progress bids, or executed bids. The DSC processor may be configured to maintain bid specific CSG ids for mobility management of lessee wireless devices in a lessor network. The DSC processor may be configured to handover wireless devices from lessee network to lessor network. The DSC processor may be configured to keep track of congestion states of the eNodeBs in its network, select target eNodeBs for handovers, and/or manage traffic on the eNodeBs. The DSC processor may also be configured to manage resource arbitration within a network.
In an embodiment, a DSC processor may be configured to offload wireless devices based on policies, network load or congestion of a lessee eNodeB, or network load/congestion of a lessor eNodeB. The DSC processor may be configured to offload the wireless devices from a first component in a lessor network to a second component in the lessor network. The DSC processor may be configured to handover a wireless device from lessor network back to lessee network to which the wireless device originally connected (or its home network).
In the various embodiments, a DPC processor may be configured to coordinate resource usage and allocation by acting as gateway between a lessee DSC and a lessor DSC. The DPC processor may be configured to serve as a resource arbitrage broker between a lessor DSC and a lessee DSC. The DPC processor may be configured to list resources from various lessor networks for auction, manage the auction, sending notifications of outbid, bid win, bid cancel, and/or bid withdrawal to one or more DSCs, and install bid specific charging rules in the charging or policy systems of lessee and lessor networks.
The various embodiments also include DSA components (e.g., DPC, DSC, etc.) configured to store and manage data and context information so as to improve the efficiency and speed of the DSA system. By storing and managing specific data and context information, the various embodiments allow the DSA components to perform improved DSA operations.
For example, in an embodiment, a DSC component may be configured to use data and context information to determine whether there is bandwidth available for allocation within cells serviced by the DSC in a first telecommunication network, identify a time period during which the bandwidth is available of allocation, and/or the locations (e.g., cell sites) in which bandwidth is available. The DSC component may also use the stored context information to identify an amount of bandwidth that is available for allocation (and/or the time periods, cell sites, etc.), generate a resource register request message that identifies such information, and send the generated resource register request message to a DPC component.
The DPC component may be configured to receive and use the resource register request message to update its stored data and context information. The DPC may also be configured to use its stored data and context information to determine whether to accept the received register request message. The DPC may further update its data and context information in response to accepting or rejecting the register request message from the DSC. For example, the DPC may register the amount of bandwidth identified in received message to a pool of available resources, and conduct an auction for the pool of resources.
In various embodiments, the data and context information stored by a DSC component may include an eNodeB identifier (eNB Id) for each eNodeB in its network that the DSC manages, and a bid identifier list (Bid Id list) for each active resource bid. For each eNodeB identifier (eNB Id), the DSC component may further store eNodeB congestion state information and a bid id list. For each bid, the DSC component may further store a bid state, a bid role, a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid and cell identifier list, and/or a closed subscriber group identifier. Each of these information elements is discussed in detail further below.
In overview, the value of the bid state information element may be one of “auction-in-progress,” “bid-won,” “bid-cancelled,” “bid withdrawn,” “bid-resource allocated,” “bid-resource-in-use,” “bid-resource-expired,” or “null.” The bid role information element may include information identifying the role of the DSC component (e.g., “lessor,” “lessee,” etc.). The bid bandwidth information element may identify the uplink and/or downlink bandwidth that is available as part of a bid. The bid start time information element may identify a time when the resource will be available for bidding, allocation, or use. The bid expiry time information element may identify a time when the resource will expire. The lessor network (or lessor PLMN) may identify the network that has won a bid for the access and use of a resource. The grid and cell identifier list may be a list of grids and/or cells that are part of the bid. The closed subscriber group identifier may be the CSG Id associated with the bid, and set to zero until the time a bid is won by a lessor and/or the DPC installs a CSG Id.
The data and context information stored by a DPC component may include a DSC list that identifies each DSC that is registered with the DPC component, the role of each DSC, the PLMN of the DSC, and the IP address of the DSC. In addition, the DPC component may also store bid identifier list (Bid Id list) for each active resource bid. For each of these bids, the DPC may further store, a bid state, a bid role, a bid winners list, a bid winner, a bid bandwidth, a bid start time, a bid expiry time, a lessor network identifier, a grid and cell identifier list, and a closed subscriber group identifier. Each of these information elements is discussed in detail further below.
In overview, the value of the bid state information element may be one of “auction-in-progress,” “bid-won,” “bid-cancelled,” “bid withdrawn,” “bid-resource allocated,” “bid-resource-in-use,” “bid-resource-expired,” or “null.” The bidders list may include a DCS identifiers for each DSC participating in the auction/DSA operations. The bid role information element may include information identifying the role of each registered DSC component (e.g., “lessor,” “lessee,” etc.) in the auction/DSA operations. The bid winner information element may include a DSC Id and PLMN Id of a winning bidder. The bid bandwidth information element may identify the uplink and/or downlink bandwidth that is available as part of a bid. The bid start time information element may identify a time when the resource will be available. The bid expiry time information element may identify a time when the resource will expire. The lessor network (or lessor PLMN) may identify the network that has won a bid for the access and use of a resource. The a grid and cell identifier list may be a list of grids and/or cells that are part of the bid. The closed subscriber group identifier may be the CSG Id associated with the bid, and set to zero until the time a bid is won by a lessor and/or the DPC installs a CSG Id.
The various embodiments may be implemented within a variety of communication systems, examples of which are illustrated in
The access gateway 113 may be any logical and/or functional component that serves as the primary point of entry and exit of wireless device traffic and/or connects the wireless devices 102 to their immediate service provider and/or packet data networks (PDNs). The access gateway 113 may forward the voice, data, and control signals to other network components as user data packets, provide connectivity to external packet data networks, manage and store contexts (e.g. network internal routing information, etc.), and act as an anchor between different technologies (e.g., 3GPP and non-3GPP systems). The access gateway 113 may coordinate the transmission and reception of data to and from the Internet 105, as well as the transmission and reception of voice, data and control information to and from an external service network 104, the Internet 105, other base stations 111, and to wireless devices 102.
In various embodiments, the base stations 111 and/or access gateway 113 may be coupled (e.g., via wired or wireless communication links) to a dynamic spectrum arbitrage (DSA) system configured to dynamically manage the availability, allocation, access, and use of various network resources (e.g., RF spectrum, RF spectrum resources, etc.). The DSA system is discussed in detail further below.
In the example illustrated in
The BSC/PCU 108, BSC/PCF 110, and RNC 114 components may process the GPRS, CDMA, and UMTS data, respectively, and send the processed data to a component within the core network 120. More specifically, the BSC/PCU 108 and RNC 114 units may send the processed data to a serving GPRS support node (SGSN) 122, and the BSC/PCF 110 may send the processed data to a packet data serving node (PDSN) and/or high rate packet data serving gateway (HSGW) component (PDSN/HSGW) 126. The PDSN/HSGW 126 may act as a connection point between the radio access network and the IP based PCEF/PGW 128. The SGSN 122 may be responsible for routing the data within a particular geographical service area, and send signaling (control plane) information (e.g., information pertaining to call setup, security, authentication, etc.) to an MME 130. The MME 130 may request user and subscription information from a home subscriber server (HSS) 132, perform various administrative tasks (e.g., user authentication, enforcement of roaming restrictions, etc.), select a SGW 118, and send administrative and/or authorization information to the SGSN 122.
The SGSN 122 may send the GPRS/UMTS data to a selected SGW 118 in response to receiving authorization information from the MME 130. The SGW 118 may store information about the data (e.g., parameters of the IP bearer service, network internal routing information, etc.) and forward user data packets to the PCEF/PGW 128. The PCEF/PGW 128 may send signaling information (control plane) to a policy control rules function (PCRF) 134. The PCRF 134 may access subscriber databases, create a set of policy rules and performs other specialized functions (e.g., interacts with online/offline charging systems, application functions, etc.). The PCRF 134 may then send the policy rules to the PCEF/PGW 128 for enforcement. The PCEF/PGW 128 may implement the policy rules to control the bandwidth, the quality of service (QoS), the characteristics of the data, and the services being communicated between the service network 104 and the end users.
In the various embodiments, any or all of the components discussed above (e.g., components 102-134) may be coupled to, or included in, a DSA system configured to dynamically manage the availability, allocation, access, and use of telecommunication resources.
In various embodiments, the DSC 144 may be included in or coupled to the E-UTRAN 140, either as part of its core network 120 or outside of the core network 120. In an embodiment, the DSC 144 may be coupled directly (e.g., via wired or wireless communication links) to one or more eNodeBs 116.
The eNodeBs 116 may be configured to communicate with the DSC 144 via the Xe interface/reference point. In various embodiments, the Xe reference point between DSC and eNodeB 116 may use the DSAAP protocol, TR-069 protocol, and/or TR-192 data model extensions to support listing available resources at the eNodeB 116 and notifying the eNodeB 116 of bid/buy confirmations. The DSC 144 may be configured to communicate with the DPC 146 via the Xd interface/reference point. The Xd reference point between DSC and DPC may use the DSAAP protocol for dynamic spectrum and resource arbitrage operations. The eNodeBs 116 may be interconnected, and configured to communicate via an X2 interface/reference point, which may also use the DSAAP protocol to communicate information. The eNodeBs 116 may be configured to communicate with components in the core network 120 via the S1 interface. For example, the eNodeBs 116 may be connected to an MME 130 via the S1-MME interface and to a SGW 118 via the S1-U interface. The S1 interface may support a many-to-many relation between the MMEs 130, SGWs 118, and eNodeBs 116.

The eNodeBs 116 may be configured to provide user plane (e.g., PDCP, RLC, MAC, PHY) and control plane (RRC) protocol terminations towards the wireless device 102. That is, the eNodeBs 116 may act as a bridge (e.g., layer 2 bridge) between the wireless devices 102 and the core network 120 by serving as the termination point of all radio protocols towards the wireless devices 102, and relaying voice (e.g., VoIP, etc.), data, and control signals to network components in the core network 120. The eNodeBs 116 may also be configured to perform various radio resource management operations, such as controlling the usage of radio interfaces, allocating resources based on requests, prioritizing and scheduling traffic according to various quality of service (QoS) requirements, monitoring the usage of network resources, etc. In addition, the eNodeBs 116 may be configured to collect radio signal level measurements, analyze the collected radio signal level measurements, and handover wireless devices 102 (or connections to the mobile devices) to another base station (e.g., a second eNodeB) based on the results of the analysis.
The DSC 144 and DPC 146 may be functional components configured to manage the dynamic spectrum arbitrage process for sharing radio frequency and other network resources between different E-UTRANs 140.

The DSC 144 may be configured to handover wireless devices 102 from lessee network to lessor network (i.e., perform handins), and handover wireless devices 102 from lessor network back to lessee network (i.e., perform backoff).
The DSC 144 may also be configured to track congestion states of eNodeBs, select target eNodeBs for handovers, and manage traffic on lessor eNodeBs. The DSC 144 may be configured to offload users based on configured policies (e.g. offload lower priority users, offload higher priority users, offload users with specific QoS, etc.) from lessee networks to other less loaded eNodeBs 116 within a lessor network. The DSC 144 may also perform backoff operations to handover a wireless device 102 from lessor network back to the lessee network. The DSC 144 may also be configured to monitor, manage, and/or maintain historic congestion information that is collected or received from one or more eNodeBs in the system.
The DPC 146 may be configured to perform various operations (e.g., via modules 167-171) to provide various functions, including functioning as a resource arbitrage broker between the DSCs 144 of lessor and lessee networks (e.g., PLMNs), listing resources from various lessor networks for auction, and managing the auction process. The DPC 146 may be configured to send notifications of outbid, bid win, bid cancel and bid withdrawal and bid expiry to DSCs 144, install bid specific charging rules in the online and/or offline charging systems of lessee and lessor networks, and coordinate resource usage between DSCs 144 by acting as gateway between lessee and lessor DSCs 144.
The DSCs 144a, 144b may be configured to communicate with the DPC 146 via Xd interface. The DSCs 144a, 144b may also be connected, directly or indirectly, to various network components in their respective core networks 120a, 120b, such as a PCRF 134, HSS 132 and a PCEF/PGW 128 (not illustrated in
In addition to the above-mentioned connections and communication links, the system 103 may include additional connections/links to accommodate data flows and communications between components in different E-UTRANs (e.g., E-UTRANS 140a and 140b). For example, the system 103 may include a connection/communication link between an eNodeB 116b in the second E-UTRAN 140b to an SGW 118 in the first E-UTRAN 140a. As another example, the system 103 may include a connection/communication link between a SGW 118 in the second E-UTRAN 140b to a PGW 128 in the first E-UTRAN 140a. To focus the discussion of the relevant embodiments, these additional components, connections, and communication links are not illustrated in
As is discussed in detail further below, the DSCs 144a, 144b may be configured to send information regarding the availability of spectrum resources (e.g., information received from an eNodeB, PCRF, PCEF, PGW, etc.) to the DPC 146. This information may include data relating to current and expected future usage and/or capacity of each network or sub-network. The DPC 146 may be configured to receive and use such information to intelligently allocate, transfer, manage, coordinate, or lease the available resources of the first E-UTRAN 140a to the second E-UTRAN 140b, and vice versa.
For example, the DPC 146 may be configured to coordinate the allocation of spectrum resources to the second E-UTRAN 140b (i.e., lessee network) from the E-UTRAN 140a (i.e., lessor network) as part of the dynamic spectrum arbitrage operations. Such operations may allow a wireless device 102 that is wirelessly connected to the eNodeB 116b in the second E-UTRAN 140b via a communication link 143 to be handed off to an eNodeB 116a in the first E-UTRAN 140a so that it may use the allocated spectrum resources of the first E-UTRAN 140a. As part of this handoff procedure, the wireless device 102 may establish a new connection 141 to the eNodeB 116a in the first E-UTRAN 140a, terminate the wireless connection 143 to the original eNodeB 116b, and use the allocated resources of the first E-UTRAN 140a as if they are included in the second E-UTRAN 140b. The DSA operations may be performed so that the first DSC 144a is a lessor DSC for a first resource/period of time, and a lessee DSC for a second resource or another period of time.
In an embodiment, the DSA and/or handoff operations may be performed so that the wireless device 102 maintains a data connection to (or a data connection that is managed by) the original network after it is handed off. For example, DSA and/or handoff operations may be performed so that the wireless device 102 maintains a dataflow connection to a PGW 128 in the second E-UTRAN 140b after being handed off to the eNodeB 116a in the first E-UTRAN 140a.
In block 202, the DPC 146 may establish a first communication link to a first DSC 144a in a first communication network (e.g., E-UTRAN, etc.). In block 204, the DPC 146 may establish a second communication link to a second DSC 144b in a second communication network. In block 206, the DPC 146 may determine whether radio frequency (RF) spectrum resources are available for allocation within the second communication network. This may be accomplished by using the DSAAP protocol to communicate with a DSC 144 in the second communication network via the second communication link, which may be a wired or wireless communication link. In block 208, the DPC 146 may determine the amount of RF spectrum resources that are available for allocation. In block 210, the DPC 146 may perform various operations to allocate all or a portion of the available RF resources of the second communication network for access and use by wireless devices 102 in the first communication network.
In block 212, the DPC 146 may send a communication message to the first DSC 144a (e.g., by using the DSAAP protocol) to inform the first communication network that the use of the allocated RF spectrum resources may begin. In block 214, the DPC 146 may record a transaction in a transaction database identifying an amount of RF spectrum resources allocated for use by the first communication network.
In block 216, the DPC 146 may receive a communication message from the second DSC 144b that includes information indicating that the allocated resources have been consumed and/or requesting that the allocated resources be released. In block 218, the DPC 146 may send a resource consumed/release message to the first DSC 144a to cause the first network to terminate its use of the allocated resources.
In operation 252, a processing core in a DPC 146 component may receive a “request for resources” communication message from a first DSC 144a component in a first network (e.g., E-UTRAN, etc.). It should be understood that the “request for resources” communication message and all other communication messages discussed in this application may be DSAAP messages.
The “request for resources” communication message may include information suitable for informing the DPC 146 that the first network is interested in purchasing, leasing, accessing, and/or using resources from other networks. The “request for resources” communication message may also include information suitable for identifying the types and/or amounts of resources (e.g., RF spectrum resources, etc.) that are requested by the first network, the types and capabilities of the wireless devices 102 to which the requested resources will be allocated, and other similar information.
In operations 254, 256, and 258 the DPC 146 may generate and send a “resource inquiry” communication message to each of a second DSC 144b component in a second network, a third DSC 144c component in a third network, and a fourth DSC 144d component in a fourth network, respectively. The DPC 146 may be configured to generate the “resource inquiry” communication messages to include various component, device, and resource requirements, criteria, and information. For example, the DPC 146 may generate a “resource inquiry” communication message to include information identifying the types, capabilities, and geographic criteria of user wireless devices 102 in the first network (and other networks) to which resources are to be allocated. The geographic criteria may include a geographic location, a geographic polygon, and/or license area for a user wireless device 102 to which resources will be allocated.
In operations 260 and 262, the DPC 146 may receive “resource inquiry response” communication messages from the second and third DSCs 144b, 144c. These “resource inquiry response” communication messages may include information identifying the availability of excess resources that comply with the requirements/criteria included in the resource inquiry messages. In operation 264, the DPC 146 may receive another “resource inquiry response” communication message from the fourth DSC 144d. This “resource inquiry response” communication messages may include information indicating that the fourth network does not include resources that meet the requested requirements/criteria.
In an embodiment, as part of operations 260-264, the DPC 146 may update a database record to identify the second and third networks as having resources available for allocation and/or to identify the fourth network as not including such resources.
In operation 266, the DPC 146 may generate and send a “resource availability” communication message to a plurality of DSCs in a plurality of networks, including the first DSC 144a in the first network. The DPC 146 may be configured to generate the “resource availability” communication message to include information that is suitable for informing the networks that resources are available for allocation. In an embodiment, the DPC 146 may be configured to inform the networks that resources are available for allocation by broadcasting a communication signal that includes information suitable for informing the networks that resources are available for allocation via auction and/or an auction start time for the auction.
In operation 268, the DPC 146 may receive a “resource reservation request” communication message from the first DSC 144a. The received “resource reservation request” communication message may include information suitable for informing the DPC 146 that the first network intends to participate in the auction and/or bid on at least a portion of the available resources.
In operations 270 and 272, the DPC 146 may send the “resource reservation request” communication message to the second and third DSCs 144b, 144c, respectively. The “resource reservation request” communication message may include information suitable for causing the second and third DSCs 144b, 144c to reserve all or a portion of their available resources for allocation and use by other networks.
In operations 274 and 276, the DPC 146 may receive a “resource reservation response” communication message from each of the second and third DSCs 144b, 144c. The “resource reservation response” messages may include information suitable for informing the DPC 146 that the requested resources that have been reserved and/or information suitable for identifying the reserved resources.
Optionally, in operation block 278, the DPC 146 may pool the reserved resources for allocation and use by wireless devices 102 in other networks (e.g., the first network). For example, the DPC 146 may combine a block of spectrum reserved in the second network with a block of spectrum reserved in the third network. As another example, the DPC 146 may pool the resources available in the first and fourth channels of a block of spectrum reserved in the second network.
In operation 280, the DPC 146 may receive “resource bid” communication messages from a plurality of networks, including from the first DSC 144a in the first network. Each “resource bid” communication message may include a bid or offer for accessing, using, leasing, and/or purchasing a resource, as well as other related bid information (e.g., price, requested allocation/access methods, etc.). As part of operation 280, the DPC 146 may determine whether the received resource bids comply with the policies and rules of the DSA system and/or with requirements set forth by the networks offering the resources for allocation (e.g., meet the minimum asking price, etc.).
In operation 282, the DPC 146 may accept the bid/offer from the first network in response to determining that the resource bid received from the first network complies with the policies/rules of the DSA system and with requirements set forth by the resource offering network (e.g., offers a monetary amount for the use of all or a portion of the resources in the pool of available resources that is greater than or equal to a minimum amount specified by the second network). Also in operation 282, the DPC 146 may generate and send a “bid acceptance” communication message to the first DSC 144a.
In operation 284, the DPC 146 may allocate the resources of the second network for access and used by wireless devices 102 in the first network by sending an “assign resources request” communication message to the second DSC 144b. That is, in operation 284, the DPC may determine that the portion of the resources (e.g., in the pool of available resources) won by the first DSC 144a are fully available via the second network, and in response, only send the assign resources request message to the second network.
In operation 286, the DPC 146 may receive a “resources allocated” communication message from the second DSC 144b. In operation 288, the DPC 146 may send the “resources allocated” communication message to the first DSC 144a to inform the first network that the resources have been allocated for access and used by its wireless devices 102 and/or that the use of the allocated resources may begin. In operation block 290, the DPC 146 may record a transaction in a transaction database identifying these resources as being allocated for access and use by the first network.
In operation 292, the DPC 146 may receive a “release resources” communication message from the second DSC 144b that includes information indicating that the allocated resources have been consumed and/or information suitable for requesting that the allocated resources be released. In operation 294, the DPC 146 may send a resource consumed/release message to the first DSC 144a to cause the first network to terminate its use of the allocated resources.

In block 316, the second DSC 144b may generate a resource allocation report, and send the generated resource allocation report to the DPC 146 (e.g., via a resource communication message). The DSC 144b may be configured to generate the resource allocation report to include information identifying the resources (or portions or amounts of resources) that are available for allocation and/or that have been marked, designated, or allocated by the second network.
In block 320, the DPC 146 may receive various resource status and allocation reports from DSCs 144 in many different networks, including the first and second DSCs 144a, 144b in the first and second networks. These reports may include information identifying various characteristics, criteria, requirements, and conditions of the networks and their components, such as the ratio of the detected user traffic to the total available spectrum resources, the amount of resources that are required by a network, the amount of resources that are available for allocation in a network, the types and capabilities of the wireless devices 102 that will use the allocated resources, system requirements that must be met before the wireless devices 102 access the allocated resources, network rules and policies with respect to access and use of resources, and other similar information.

In operation 1654, the DPC 146 may generate and send a DSC DE-REGISTER message to the DSC 144. The DPC 146 may be configured to generate the DSC DE-REGISTER message to include any or all of a message type information element (IE), a message ID IE, a backoff timer IE, and a cause IE that identifies a cause for the termination of operations (e.g., overload, unspecified, etc.). In operation block 1656, the DPC 146 may clear all the related resources associated with the DSC 144 and/or perform other similar operations to de-register the DSC 144.
In operation block 1658, the DSC 144 may perform various de-registration failure response operations based on the information included in the received DSC DE-REGISTER message. For example, the DSC 144 may be configured to not retry registration to the same DPC 146 for at least the duration indicated in the backoff timer IE included in the received DSC DE-REGISTER message when the value of the cause IE in the DSC DE-REGISTER message is set to “overload.”
In operation block 1702, the DSC 144 may detect an error or error condition (e.g., a protocol error, etc.). In operation 1704, the DSC 144 may generate and send an ERROR INDICATION message to the DPC 146. The DSC 144 may be configured to generate the ERROR INDICATION message to include any or all of a message type information element (IE), a message ID IE, cause IE, and a criticality diagnostics IE. The cause IE may include information suitable for use in identifying a cause or type of the error (e.g., transfer syntax error, abstract syntax error, logical error, etc.). The criticality diagnostics IE may include a procedure code IE, a triggering message IE, and a procedure criticality IE. In operation block 1706, the DSC 144 and/or DPC 146 may perform various error-response operations based on the detected error or information included in the received ERROR INDICATION message. The error detection and response operations are discussed in detail further below.
In operation block 1752, the DPC 146 may detect an error condition. In operation 1754, the DPC 146 may generate and send an ERROR INDICATION message to the DSC 144. The DPC 146 may be configured to generate the ERROR INDICATION message to include a cause information element (IE) that identifies a cause for the error. In operation block 1756, the DSC 144 and/or DPC 146 may perform various error-response operations based on the information included in the received ERROR INDICATION message.
As mentioned above, the DSC 144 and DPC 146 may be configured perform various error-response or failure response operations in response to detecting an error or failure condition. As part of these operations, the DSC 144 and/or DPC 146 may identify the type or cause of the error/failure condition, and tailor their responses based on the identified type or cause. For example, the DSC 144 and/or DPC 146 may be configured to determine whether a detected error is a protocol error, and tailor their responses accordingly.
Protocol errors include transfer syntax errors, abstract syntax errors, and logical errors. A transfer syntax error may occur when the receiving functional DSAAP entity (e.g., DSC, DPC, etc.) is not able to decode the received physical message. For example, transfer syntax errors may be detected while decoding ASN.1 information in a received message. In an embodiment, the DSC 144 and DPC 146 components may be configured to retransmit or re-request a DSAAP message in response to determining that a detected error is a transfer syntax error (e.g., as part of the error-response operations).
An abstract syntax error may occur when the receiving functional DSAAP entity (e.g., DSC, DPC, etc.) receives information elements (IEs) or IE groups that cannot be comprehended or understood (i.e., an unknown IE id). An abstract syntax error may also occur when the entity receives an information element (IE) for which a logical range (e.g., allowed number of copies) is violated. The DSC 144 and DPC 146 components may be configured to detect or identify these types of abstract syntax errors (i.e., cannot comprehend abstract syntax error), and in response, perform error-response operations based on criticality information included in the corresponding DSAAP message. Additional details regarding these operations and the criticality information are provided further below.
An abstract syntax error may also occur when the receiving functional DSAAP entity does not receive IEs or IE groups, but according to the specified presence of the object, the IEs or IE groups should have been present in the received message. The DSC 144 and DPC 146 components may be configured to detect or identify these particular types of abstract syntax errors (i.e., missing IE or IE group), and in response, perform error-response operations based on criticality information and presence information for the missing IE/IE group. Additional details regarding these operations, criticality information, and presence information are provided further below.
An abstract syntax error may also occur when the receiving entity receives IEs or IE groups that are defined to be part of that message in wrong order or with too many occurrences of the same IE or IE group. In addition, an abstract syntax error may also occur when the receiving entity receives IEs or IE groups, but according to the conditional presence of the concerning object and the specified condition, the IEs or IE groups should not have been present in the received message. The DSC 144 and DPC 146 components may be configured to detect or identify such abstract syntax errors (i.e., wrong order, too many occurrences, erroneously present, etc.), and in response, reject or terminate a procedure or method associated with the error (e.g., the method that caused the error). The DSC 144 and DPC 146 components may reject or terminate the procedure/method as part of the error-response operations.
In the various embodiments, the DSC 144 and DPC 146 components may be configured to continue to decode, read, or process a DSAAP message after detecting, identifying, or determining that an abstract syntax error occurred for that message. For example, the DSC 144 and DPC 146 components may skip a portion of the message that includes an error, and continue processing the other portions of the message. As part of this continued processing, the DSC 144 and DPC 146 components may detect or identify additional abstract syntax errors.
In an embodiment, the DSC 144 and DPC 146 components may be configured to perform error-response operations for each detected abstract syntax error and/or based on the criticality information and presence information for the IE/IE group associated with the abstract syntax error.
As mentioned above, each DSAAP message may include, or may be associated with, criticality information, presence information, range information, and assigned criticality information. In the various embodiments, a receiving functional DSAAP entity (e.g., DSC, DPC, etc.) may be configured to use any or all of such information (e.g., criticality information, presence information, etc.) when detecting an error, identifying the type of the error, or the specific error-response that are to be performed. That is, the entity may perform different operations depending on the values of the criticality information, presence information, range information, and/or assigned criticality information.
In an embodiment, the receiving functional DSAAP entity (e.g., DSC, DPC, etc.) may be configured to use the presence information included in a DSAAP message when identifying the type of error and the specific error-response operations that are to be performed for the identified error type. For example, the entity may use the presence information to determine whether the presence of an information element (IE) is optional, conditional, or mandatory (e.g., with respect to RNS application) for that message or communication. The entity may determine that an abstract syntax error has occurred when a received message is missing one or more information elements that are determined to be mandatory (or conditional when the condition is true).
In an embodiment, the receiving functional DSAAP entity (e.g., DSC, DPC, etc.) may be configured use the criticality information when identifying the specific error-response operations that are to be performed. That is, each DSAAP message may include criticality information for each individual information element (IE) or IE group included in that message. The values of criticality information for each IE or IE group may include “Reject IE,” “Ignore IE and Notify Sender,” and “Ignore IE.” The receiving entity (e.g., DSC, DPC, etc.) may use this criticality information to determine that an IE, an IE group, or an EP is incomprehensible, identify the condition as an abstract syntax error (i.e., a cannot comprehend abstract syntax error), and/or to identify the error-response operations that are to be performed (e.g., reject, ignore, notify, etc.).
In an embodiment, the receiving entity (e.g., DSC, DPC, etc.) may be configured to reject a method/procedure and initiate a DSAAP error indication method (discussed above with reference to
For example, when a message that initiates a method/procedure (e.g., a DSC REGISTER REQUEST message, etc.) is received, determined to include one or more IEs/IE groups that are incomprehensible and marked as “Reject IE,” the receiving entity may the reject the method/procedure by not executing any of the functional requests included in that message. The receiving entity may also report the rejection of one or more IEs/IE groups using the message normally used to report unsuccessful outcome of the procedure. When the information in the received initiating message is insufficient and cannot be used to determine a value for all IEs that are required to be present in the message used to report the unsuccessful outcome of the procedure, the receiving entity may terminate the procedure and initiate a DSAAP error indication method/procedure.
As a further example, when a message initiating a method/procedure that does not have a message to report unsuccessful outcome is received, and that message includes one or more IEs/IE groups marked with “Reject IE” which the receiving entity does not comprehend, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As yet another example, when a response message (e.g., a DSC REGISTER RESPONSE message, etc.) is received that includes one or more IEs marked with “Reject IE” which the receiving entity does not comprehend, the receiving entity may consider the method/procedure as being unsuccessfully terminated, and initiate a local error handling method.
In an embodiment, the receiving entity (e.g., DSC, DPC, etc.) may be configured to ignore or skip a method/procedure and initiate an DSAAP error indication method (discussed above with reference to
As an example, when a message initiating a method/procedure is received containing one or more IEs/IE groups marked with “Ignore IE and Notify Sender” which the receiving entity does not comprehend, the receiving entity may ignore the content of the incomprehensible IEs/IE groups, continue with the method/procedure as if the incomprehensible IEs/IE groups were not received (except for the reporting) using the comprehended IEs/IE groups, and report in the response message of the method/procedure that one or more IEs/IE groups have been ignored. When the information received in the initiating message is insufficient to determine a value for all IEs that are required to be present in the response message, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As a further example, when a message initiating a method/procedure that does not have a message to report the outcome of the method/procedure is received containing one or more IEs/IE groups marked with “Ignore IE and Notify Sender” which the receiving entity does not comprehend, the receiving entity may ignore the content of the not comprehended IEs/IE groups, continue with the method/procedure as if the not comprehended IEs/IE groups were not received (except for the reporting) using the understood IEs/IE groups, and initiate a DSAAP error indication method/procedure to report that one or more IEs/IE groups have been ignored.
As yet another example, when a response message is received containing one or more IEs/IE groups marked with “Ignore IE and Notify Sender” which the receiving entity does not comprehend, the receiving entity may ignore the content of the not comprehended IE/IE groups, continue with the method/procedure as if the not comprehended IEs/IE groups were not received (except for the reporting) using the understood IEs/IE groups and initiate a DSAAP error indication method/procedure.
In an embodiment, the receiving entity (e.g., DSC, DPC, etc.) may be configured to ignore or skip a method/procedure in response to determining that an information element (IE) included in a message received during the performance of that method/procedure is incomprehensible, and that value of the criticality information for that IE is set to “Ignore IE.”
As an example, when a message initiating a method/procedure is received containing one or more IEs/IE groups marked with “Ignore IE” which the receiving entity does not comprehend, the receiving entity may ignore the content of the not comprehended IEs/IE groups and continue with the method/procedure as if the not comprehended IEs/IE groups were not received using only the understood IEs/IE groups.
As a further example, when a response message is received that includes one or more IEs/IE groups marked with “Ignore IE” which the receiving entity does not comprehend, the receiving entity may ignore the content of the not comprehended IEs/IE groups and continue with the method/procedure as if the not comprehended IEs/IE groups were not received using the understood IEs/IE groups.
When reporting not comprehended IEs/IE groups marked with “Reject IE” or “Ignore IE and Notify Sender” using a response message defined for the method/procedure, the Information Element Criticality Diagnostics IE may be included in the Criticality Diagnostics IE for each reported IE/IE group.
In an embodiment, the receiving entity (e.g., DSC, DPC, etc.) may be configured to initiate a DSAAP error indication method (discussed above with reference to
In an embodiment, the receiving entity (e.g., DSC, DPC, etc.) may be configured to treat the missing IE/IE group according to the criticality information for the missing IE/IE group in the received message specified in the version of the present document used by the receiver.
As an example, the receiving entity (e.g., DSC, DPC, etc.) may be configured to not execute any of the functional requests of a received initiating message in response to determining that the received message is missing one or more IEs/IE groups with specified criticality “Reject IE.” The receiving entity may reject the method/procedure and report the missing IEs/IE groups using the message normally used to report unsuccessful outcome of the method/procedure. When it is determined that the information received in the initiating message was insufficient to determine a value for all IEs that are required to be present in the message used to report the unsuccessful outcome of the method/procedure, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As a further example, when a received message initiating a method/procedure that does not have a message to report unsuccessful outcome is missing one or more IEs/IE groups with specified criticality “Reject IE”, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As yet another example, when a received response message is missing one or more IEs/IE groups with specified criticality “Reject IE, the receiving entity may consider the method/procedure as unsuccessfully terminated and initiate a local error handling method/procedure.
As another example, when a received message initiating a method/procedure is missing one or more IEs/IE groups with specified criticality “Ignore IE and Notify Sender”, the receiving entity may ignore that those IEs are missing and continue with the method/procedure based on the other IEs/IE groups present in the message and report in the response message of the method/procedure that one or more IEs/IE groups were missing. When the information received in the initiating message is insufficient to determine a value for all IEs that are required to be present in the response message, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As another example, when a received message initiating a method/procedure that does not have a message to report the outcome of the method/procedure is missing one or more IEs/IE groups with specified criticality “Ignore IE and Notify Sender”, the receiving entity may ignore that those IEs are missing and continue with the method/procedure based on the other IEs/IE groups present in the message and initiate a DSAAP error indication method/procedure to report that one or more IEs/IE groups were missing.
As another example, when a received message a received response message is missing one or more IEs/IE groups with specified criticality “Ignore IE and Notify Sender”, the receiving entity may ignore that those IEs are missing and continue with the method/procedure based on the other IEs/IE groups present in the message and initiate a DSAAP error indication method/procedure to report that one or more IEs/IE groups were missing.
As another example, when a received message initiating a method/procedure is missing one or more IEs/IE groups with specified criticality “Ignore IE”, the receiving entity may ignore that those IEs are missing and continue with the method/procedure based on the other IEs/IE groups present in the message.
As another example, when a received response message is missing one or more IEs/IE groups with specified criticality “Ignore IE”, the receiving entity may ignore that those IEs/IE groups are missing and continue with the method/procedure based on the other IEs/IE groups present in the message.
The receiving entity (e.g., DSC, DPC, etc.) may be configured to respond to messages that include IEs or IE groups that received in wrong order, include too many occurrences, or are erroneously present (i.e., are included and marked as “conditional” when the condition is not met) in various ways. For example, the receiving entity (e.g., DSC, DPC, etc.) may be configured to not execute any of the functional requests of a received initiating message in response to determining that the received message includes IEs or IE groups in wrong order, includes too many occurrences of an IE, or includes erroneously present IEs. The receiving entity may reject the method/procedure and report the cause value “Abstract Syntax Error (Falsely Constructed Message)” using the message normally used to report unsuccessful outcome of the method/procedure. When the information received in the initiating message is insufficient to determine a value for all IEs that are required to be present in the message used to report the unsuccessful outcome of the method/procedure, the receiving entity may terminate the method/procedure and initiate a DSAAP error indication method/procedure.
As another example, when a message initiating a method/procedure that does not have a message to report unsuccessful outcome is received containing IEs or IE groups in wrong order or with too many occurrences or erroneously present, the receiving entity may terminate the method/procedure, and initiate a DSAAP error indication method/procedure using the cause value “Abstract Syntax Error (Falsely Constructed Message)”.
As another example, when a response message is received containing IEs or IE groups in wrong order or with too many occurrences or erroneously present, the receiving entity may consider the method/procedure as unsuccessfully terminated and initiate local error handling.
As mentioned above, protocol errors include transfer syntax errors, abstract syntax errors, and logical errors. A logical error occurs when a message is comprehended correctly, but the information contained within the message is not valid (i.e. semantic error), or describes a method/procedure which is not compatible with the state of the receiving entity.
In an embodiment, a receiving entity (e.g., DSC, DPC, etc.) may be configured to perform error response operations based on the class of the method/procedure and irrespective of the criticality information of the IE's/IE groups containing the erroneous values in response to determining/detecting an logical error.
For example, when a logical error is detected in a request message of a class 1 method/procedure, and the method/procedure has a message to report this unsuccessful outcome, this message may be sent with an appropriate cause value (i.e., in the clause IE), such as “semantic error” or “message not compatible with receiver state.” When a logical error is detected in a request message of a class 1 method/procedure, and the method/procedure does not have a message to report this unsuccessful outcome, the method/procedure may be terminated and a DSAAP error indication method/procedure may be initiated with an appropriate cause value. Where the logical error exists in a response message of a class 1 procedure, the procedure may be considered as unsuccessfully terminated and local error handling may be initiated.
When a logical error is detected in a message of a class 2 procedure, the procedure may be terminated and a DSAAP error indication procedure may be initiated with an appropriate cause value.
In the various embodiments, the receiving entity (e.g., DSC, DPC, etc.) may be configured to perform a local error handling method/procedure (as opposed to a DSAAP error indication method/procedure) when a protocol error is detected in the ERROR INDICATION message. In case a response message or error indication message needs to be returned, but the information necessary to determine the receiver of that message is missing, the procedure may be considered as unsuccessfully terminated and local error handling may be initiated. When an error that terminates a procedure occurs, the returned cause value may reflect the error that caused the termination of the procedure even if one or more abstract syntax errors with criticality “ignore and notify” have earlier occurred within the same procedure.
In operation 1802, the wireless device 102 may attach to the lessee network. In operation 1804, the first eNodeB 116a may monitor and report resource usages and node level congestion levels to the first DSC 114a. This may be accomplished by the first eNodeB 116a generating and sending a resource update message to the first DSC 144a, either directly (e.g., via the Xe interface) or via the first SGW 118a (e.g., via the S1-U interface). In an embodiment, the first eNodeB 116a may generate the resource update message to include information suitable for reporting resource usage level for multiple cells, including the cell to which the wireless device 102 is attached. In various embodiments, the first eNodeB 116a may be configured to send such resource update messages periodically or in response to detecting a condition or event (e.g., new wireless device attached, etc.).
In operation 1806, the first SGW 118a may use the information included in the received resource update message to update its resource usage records and/or forward the resource update message to the DSC 144a. In operation 1808, the first SGW 118a may start a resource update acknowledgment timer. In operation 1810, the first DSC 144a, may generate and send a resource update acknowledgment message to the first eNodeB, either directly or via the first SGW 118a. In operation 1812, the first SGW 118a may forward the resource update acknowledgment message to the first eNodeB 116a and/or use the information included in the received acknowledgment message to update its resource usage records. In operation 1814, the first SGW 118a may stop the resource update acknowledgment timer in response to receiving the acknowledgment message and/or in response to determining that the resource update acknowledgment message was received prior the expiration of the resource update acknowledgment timer.
In operations 1816-1822, the first eNodeB 116a may periodically report usage/congestion levels and the first DSC 114a and first SGW 118a may update their resource usage records, which may be accomplished by performing the same or similar operations as those performed in operations 1804-1814. Similarly, in operations 1850-1866, the second eNodeB 116b, second DSC 114b, and second SGW 118b may perform the same or similar operations as those performed as part of operations 1804-1822.
In operations 1824 and 1826, the first DSC 114a may determine whether there are excess resources available in the first network for allocation to other networks, and send a resource availability message to the DPC 146. The resource availability message may include information suitable for informing the DPC 146 of the resources determined to be available for allocation. The DPC 146 may be configured to receive, store, or maintain resource availability information for multiple DSCs and/or for multiple different networks (i.e. different PLMN IDs).
In operation 1828, the first DSC 114a may start a timer. In operations 1830 and 1832, the first DSC 114a may initiate or participate in an auction by monitoring its available/remaining resources and sending resource availability advertisements to DPC 1830. In operation 1834, the first DSC 114a may determine that the timer expired, and discontinue advertizing its resources. In operations 1870-1880, the second DSC 114b may perform the same or similar operations as those performed as part of operations 1824-1834.
In operation 1902, a DPC 146 component may establish a communication link to a DSC 144a in first communication network. In operation 1904, the DPC 146 may determine whether a telecommunication resource of the first communication network is available for allocation based on information received via the communication link. In an embodiment, the DPC 146 may determine that the telecommunication resource is available for allocation at a future date and time.
In operation 1906, the DPC 146 may broadcast a communication signal that includes information suitable for informing a plurality of communication networks that the telecommunication resource is available for allocation via an auction and including an auction start time for the auction. In operation 1908, the DPC 146 may receive bids from the plurality of communication networks for the telecommunication resource determined to be available for allocation in response to broadcasting the communication message and after the auction start time included in the broadcast communication signal. In an embodiment, receiving bids from the plurality of communication networks may include receiving bids for access and use of the telecommunication resource determined at the future date and time.
In operation 1910, the DPC 146 may accept only the bids received from authorized networks determined to be eligible to participate in the auction. For example, the DPC 146 may determine whether the telecommunication resource is compatible with each of the plurality of communication networks, authorize networks in the plurality of communication networks as being eligible to participate in the auction based on their compatibility with the telecommunication resource, and accept bids from only the authorized networks.
In operation 1912, the DPC 146 may allocate the telecommunication resource of the first communication network for access and use by a second communication network in the plurality of communication networks based on accepted bids. In an embodiment, allocating the telecommunication resource may include allocating the telecommunication resource of the first communication network for access and use by the second communication network at the future date and time. In operation 1914, the DPC 146 may send a communication message to the second communication network that includes information suitable for informing the second communication network that use of allocated telecommunication resource may begin. In operation 1916, the DPC 146 may record a transaction in a transaction database identifying the telecommunication resource as being allocated for use by the second communication network.
In operation 1918, the DPC 146 may request return of the allocated telecommunication resource. In operation 1920, the DPC 146 may broadcast a second communication signal to inform the plurality of communication networks that the telecommunication resource is available for reallocation via a second auction.

In block 2008, the DPC 146 component may allocate the resource of the first communication network for access and use by a second communication network in the plurality of communication networks. In block 2010, the DPC 146 component may broadcast a second communication signal informing the second communication network that use of allocated telecommunication resource may begin in the geographical area. In block 2012, the DPC 146 component may record a transaction in a transaction database identifying the telecommunication resource as being allocated for use by the second communication network.
In operation 2014, the DPC 146 component may request return of the allocated telecommunication resource. In operation 2016, the DPC 146 may broadcast a second communication signal to inform the plurality of communication networks that the telecommunication resource is available for reallocation via a second auction.
In an embodiment, the DSA method 2000 may further include the DPC 146 component receiving resource configuration information relating to a resource allocation scheme from a first DSC 144 in the first communication network and sending the resource configuration information to a second DSC 144 in the second communication network.

In a further embodiment, the DPC 146 component may be configured to negotiate a resource leasing scheme between the first and second communication networks for a use of the resource, and coordinating a handover of a mobile device between the first and second communication networks based on geographic boundaries defined in the resource leasing scheme. The DPC 146 may be further configured to determine the validity of a subscriber device (e.g., wireless device 102) of the second communication network based on the proximity of the subscriber device to the geographical area, level of quality of service available to the subscriber device, and/or information included in the resource leasing scheme.
In various embodiments, the DPC 146 may be configured to instruct the subscriber device to change networks or to establish a communication link to a resource in the first communication network based on the proximity of the subscriber device to the geographical area, level of quality of service available to the subscriber device, and/or terms of the resource leasing scheme. The DPC 146 may be configured to instruct a subscriber device that is actively connected to or using the telecommunication resource to change networks and/or to attach to another resource based on the proximity of the subscriber device to the geographical area.
With reference to
In block 2104, the processing core may determine whether there is bandwidth (and/or other resources) available for allocation within cells serviced by a DSC in a first telecommunication network.

With reference to
In block 2124, the processing core may receive a resource register request message. In block 2126, the processing core may determine whether to accept the received register request message based on the information included in the message and the stored data and context information. In block 2128, the processing core may update the stored data/context information and add the resources (or resource amounts) identified in the message to a pool of available resources in response to determining that the register request message is to be accepted. In block 2130, the processing core may conduct and auction and/or perform other DSA operations to determine the telecommunication network, resources, resource amounts that are to be allocated. In block 2132, the processing core may determine a bid winner, allocate resources, and update the data and context information.
The various embodiments may include or use a dynamic spectrum arbitrage application part (DSAAP) protocol and/or component that is configured to allow, facilitate, support, or augment communications between two or more DSA components (e.g., DPC, DSC, eNodeB, MME, HSS, etc.) so as to improve the efficiency and speed of the DSA system. A DSA component may be any component discussed in this application and/or any component that participates in any of the DSA operations, communications, or methods discussed in this application. As such, the DSAAP component(s) may be configured to allow, facilitate, support, or augment communications between any of the components discussed in this application, including the communications between a DPC component and a DSC component, between the DSC component and a eNodeB component, between the DSC component and an MME component, between the DSC component and an HSS component, between the MME component and the HSS component, between the eNodeB component and a wireless device, etc.
To facilitate the communications between two or more DSA components, the DSAAP component(s) may publish application programming interfaces (API) and/or include client modules that facilitate communications between the DSA components. In addition, the DSAAP component(s) may be configured to allow the DSA components to communicate specific information, use specific communication messages, and/or perform specific operations that together provide various DSA functions that further improve the efficiency and speed of the DSA system and participating networks.
As an example, the DSAAP component(s) may be configured to allow an eNodeB to communicate with a DSC component (e.g., via the Xe interface), with other eNodeBs (e.g., via an X2 interface), and with various other components (e.g., via the S1 interface). As a further example, the DSAAP component(s) may be configured to allow, facilitate, support, or augment communications between the DSC component and the DPC component so as to allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations. The DSAAP component(s) may also improve the DSA resource auctioning operations by improving the performance and efficiency of the procedures for bidding, generating invoices, advertizing resources, requesting resources, purchasing resources, validating bid credentials, etc.
In the various embodiments, all or portions of the DSAAP component may be included in one or more DSA components, such as a DPC component, a DSC component, an eNodeB component, an MME component, and an HSS component. The DSAAP component may be implemented in hardware, software, or a combination of hardware and software. In an embodiment, the DSAAP component may be configured to implement a DSAAP protocol, which may be defined over the Xe, Xd, and/or X2 reference points. In various embodiments, the Xe reference point between DSC and eNodeB may use the DSAAP protocol, TR-069 protocol, and/or TR-192 data model extensions to support listing available resources at the eNodeB and notifying the eNodeB of bid/buy confirmations. The Xd reference point between DSC and DPC may use the DSAAP protocol for dynamic spectrum and resource arbitrage operations. The X2 interface/reference point between the eNodeBs may also use the DSAAP protocol to communicate information.
In various embodiments, the DSAAP component(s) may be configured to allow the various DSA components (e.g., DSC, DPC, eNodeB, etc.) to communicate using the DSAAP protocol and/or to perform various DSAAP methods. DSAAP methods may be performed in any of the DSA systems discussed in this application, such as a system that includes a first DSC server in a first telecommunication network (e.g., a lessee network), a second DSC server in second telecommunication network (e.g., a lessor network), and a DPC server that is outside of the first and second telecommunication networks.
The various embodiments may be implemented on a variety of mobile wireless computing devices, an example of which is illustrated in
A typical cell phone 2200 also includes a sound encoding/decoding (CODEC) circuit 2208 which digitizes sound received from a microphone into data packets suitable for wireless transmission and decodes received sound data packets to generate analog signals that are provided to the speaker 2204 to generate sound. Also, one or more of the processor 2201, wireless transceiver 2206 and CODEC 2208 may include a digital signal processor (DSP) circuit (not shown separately). The cell phone 2200 may further include a ZigBee transceiver (i.e., an IEEE 802.15.4 transceiver) for low-power short-range communications between wireless devices, or other similar communication circuitry (e.g., circuitry implementing the Bluetooth® or WiFi protocols, etc.).
The embodiments described above, including the spectrum arbitrage functions, may be implemented within a broadcast system on any of a variety of commercially available server devices, such as the server 2300 illustrated in
The processors 2201, 2301, may be any programmable microprocessor, microcomputer or multiple processor chip or chips that can be configured by software instructions (applications) to perform a variety of functions, including the functions of the various embodiments described below. In some wireless devices, multiple processors 2301 may be provided, such as one processor dedicated to wireless communication functions and one processor dedicated to running other applications. Typically, software applications may be stored in the internal memory 2202, 2302, before they are accessed and loaded into the processor 2201, 2301. The processor 2201, 2301 may include internal memory sufficient to store the application software instructions. In some servers, the processor 2301 may include internal memory sufficient to store the application software instructions. In some receiver devices, the secure memory may be in a separate memory chip coupled to the processor 2201. The internal memory 2202, 2302 may be a volatile or nonvolatile memory, such as flash memory, or a mixture of both. For the purposes of this description, a general reference to memory refers to all memory accessible by the processor 2201, 2301, including internal memory 2202, 2302, removable memory plugged into the device, and memory within the processor 2201, 2301 itself.
