The present disclosure relates to wireless communications, and more particularly, to methods providing information for wireless devices and related network nodes and wireless devices.
Historically every cellular device has been equipped with a removable SIM (Subscriber Identity Module) card. Recently GSMA has published the specifications for “non-removable SIM”, referred to as the embedded SIM, eSIM, or eUICC (Embedded Universal Integrated Circuit Card). The uptake in number of connections based on this GSMA specification is projected to reach about 1 billion in 2020 in accordance with Beecham research.
Examples of usage areas for which eSIM may play a significant/critical role may range from traditional M2M (machine-to-machine) services such as Utility and Automotive to pure Connected Consumer Electronics.
A potentially important use-case for all of the above areas may be when the device (including an eUICC Card) is provisioned with its first commercial operator. This process is commonly referred to as “Bootstrapping” or “Provisioning of first operational profile.” In order for this process to work, the eUICC (embedded Universal Integrated Circuit Card) may need to be pre-provisioned with a Bootstrap mean, in short an IMSI (International Mobile Subscriber Identity) number (also referred to as an identification or identification number), to establish a cellular connection used/needed to download and/or enable a first operational profile, e.g., for a first commercial operator.
The role of facilitating the Bootstrap mean and the Bootstrapping process may be important/critical for Ericsson's DCP (Device Connection Platform) as a Service in its pursuit for new businesses where the relationship not only with the traditional operators but also with their customers, namely the device makers (e.g., Original Equipment Manufacturers or OEMs), may be increasingly important.
Use of eUICC is discussed in GSMA Embedded SIM Solution Specification. See, Reference [1], (GSMA Embedded SIM Remote Provisioning Architecture, Version 1.1, 17 Dec. 2013), the disclosure of which is hereby incorporated herein in its entirety by reference. Each eUICC may include mandatory provisioning subscription information and may also include one or more optional operational subscription(s).
Provisioning subscriptions have been a significant obstacle for eUICC commercialization, because provisioning subscriptions may require extra numbering resources (e.g., IMSI/MSISDN identification numbers are becoming more limited resources) and extra cost in a mobile network operator's HLR (Home Location Register) space (e.g., licensing cost), and provisioning subscriptions may always need to be active on the HLR to make sure each eUICC can fall back to this provisioning subscription in case of connectivity failure during its entire lifecycle due to many failure reasons. The always-active provisioning subscription in the operator network may continuously generate extra cost that operators and enterprises may be required to pay for. In summary, the extra provisioning subscription in eUICC may increase complexity and/or cost.
According to some embodiments of inventive concepts, a method may be provided to operate a wireless device including memory with dummy subscription information stored therein. The method may include transmitting an attach request message over a radio interface to a mobile communication network, with the attach request message including the dummy subscription information.

The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated herein and constitute a part of this application, illustrate certain non-limiting embodiments of inventive concepts. In the drawings:
Inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which examples of embodiments of inventive concepts are shown. Inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of inventive concepts to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present/used in another embodiment.
For purposes of illustration and explanation only, these and other embodiments of inventive concepts are described herein in the context of operating in/with a RAN (Radio Access Network) and/or a core network of a public land mobile network PLMN that communicates over radio communication channels with wireless devices. It will be understood, however, that inventive concepts are not limited to such embodiments and may be embodied generally in any type of communication network. As used herein, a wireless device (also referred to as a UE, user equipment node, mobile device, mobile terminal, wireless terminal, etc.) can include any device that receives data over a wireless interface (also referred to as a radio interface) from and/or transmits data over a wireless interface to a wireless/radio communication network, and may include, but is not limited to, a mobile telephone (“cellular” telephone), laptop/portable computer, pocket computer, hand-held computer, an M2M (machine-to-machine) device, IoT (Internet of Things) device, and/or desktop computer.
Note that although terminology from 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution) has been used in this disclosure to provide examples of embodiments of inventive concepts, this should not be seen as limiting the scope of inventive concepts to only the aforementioned system. Other wireless systems, including WCDMA, WiMax, UMB, and/or GSM, may also benefit from exploiting ideas/concepts covered within this disclosure.
Also, note that terminology such as base station (also referred to as an eNodeB, eNB, etc.) and wireless device (also referred to as a UE, user equipment node, mobile device, mobile terminal, wireless terminal, etc.) should be considering non-limiting.
Each VPLMN MN1 and MN2 may include a Radio Access Network RAN (e.g., RAN1 and RAN2) and a core network, with the core network including nodes, such as a mobile switching center MSC (201a-1 and 201a-2), a Signaling Gateway Supporting Node SGSN (201b-1 and 201b-2), a Domain Name System DNS, one or more Firewalls, a Signaling Transfer Point STP, and/or an Internet Protocol IP (Internet Protocol) router (IPR1 and IPR2), coupled over an SS7 (Signaling System No. 7) Sigtran (Signaling Transport) network (e.g., using a Gn interface/interfaces). Each VPLMN network may thus support uplink and downlink communications with mobile devices such as wireless device WD.
In EDCP, a multi-tenant HLR (Home Location Register) and other core network nodes (e.g., Gateway GPRS Support Node GGSN, Short Message Service Center SMSC, etc.) may be hosted in a cloud HPLMN (home public land mobile network) as a core network service for all our on-boarded mobile network operators (e.g., MNO1 and MNO2). All M2M (machine-to-machine) subscribers of the DCP network may be registered and/or stored on DCP HLR. The DCP may provide connectivity as a service to all operators (e.g., operators MNO1 and MNO2) rather than selling the standard core network nodes (e.g., HLR, GGSN, SMSC, etc.) for each VPLMN network.
On top of DCP core network services supported by the cloud HPLMN network of
As shown in
Each base station BS may include a transceiver circuit (also referred to as a transceiver or radio interface) configured to provide radio communications with a plurality of wireless devices, a network interface circuit (also referred to as a network interface) configured to provide communications with other base stations of the RAN (e.g., over the X2 interface), a processor circuit (also referred to as a processor) coupled to the transceiver circuit and the network interface circuit, and a memory circuit coupled to the processor circuit. The memory circuit may include computer readable program code that when executed by the processor circuit causes the processor circuit to perform operations according to embodiments disclosed herein. According to other embodiments, processor circuit may be defined to include memory so that a memory circuit is not separately provided.
For ease of illustration,
According to some embodiments of inventive concepts, a DCP dummy connection may be established between a wireless device WD and initial registration node IRN of the cloud HPLMN network to provide provisioning connectivity for an eUICC wireless device WD. An eUICC solution may thus be enabled without using/needing a so-called eUICC provisioning subscription (see, Reference [1], GSMA Embedded SIM Remote Provisioning Architecture, Version 1.1, 17 Dec. 2013).
According to some embodiments of inventive concepts, a DCP dummy IMSI (International Mobile Subscriber Identity) is saved in the wireless device, and the DCP dummy IMSI is stored in the at the DCP cloud system. The DCP dummy IMSI is NOT a real IMSI and is NOT provisioned in VPLMN HLR. The dummy SIM (IMSI) number range is defined and managed by DCP dummy system, and it is NOT in any commercial IMSI number ranges from any existing operators today.
The DCP dummy IMSI (also referred to as a dummy IMSI number) can be used by the wireless device WD to attach to the network (and to DCP dummy HLR), and to set up a temporary PDP context (using DCP dummy APN, DCP, dummy PDP, etc.) or default dummy bearer with DCP dummy GGSN. The DCP dummy IMSI may only allow a provisioning bearer for remote subscription provisioning purposes, and not for normal traffic. The traffic restriction may be enforced using the DCP dummy APN, which may only allow traffic to and from the DCP dummy system, with no other sources (e.g., the Internet) being allowed.
A policy control (triggering) component may also be used/needed. When a 1st registration (location update request) is received at DCP dummy HLR, it may need to check predefined business rules such as: whether the mobile device has arrived in the destination country (PLMN MCC MNC ID=Destination MCC MNC ID) or just passing by an intermediate country; whether the device shall be re-provisioned with a localized subscription now, or later after a time period; which local MNO (e.g., mobile network operator MNO1 or MNO2) has a priority to be selected to provide the local subscription and download to the eUICC; and/or other pre-defined business rules.
The initial registration node IRN (also referred to as DCP Dummy System) may include an IRN HLR (also referred to as DCP Dummy HLR), an IRN GGSN (also referred to as DCP Dummy GGSN), Policy Control Function, and IRN AAA (also referred to as DCP Dummy AAA). Those functions/modules can be implemented within one software node/server, referred to as an initial registration node or DCP Dummy System.
Embodiments of inventive concepts may be implemented using operations discussed in greater detail below with respect to
For provisioning to be performed according to embodiments of inventive concepts, the eUICC wireless device WD has a preloaded DCP dummy subscription that may be stored in memory 307 during its manufacture or during an initial personalization. eUICC wireless device is thus enabled with the DCP dummy subscription before it is provisioned with a new operational subscription(s) from a mobile network operator for a VPLMN. As shown in
According to some embodiments, a pool of dummy identifications (e.g., dummy IMSI's) may be maintained in IRN memory 507. When a eUICC wireless device is manufactured, the manufacturer may remotely fetch an available dummy identification from the pool of dummy identifications in IRN memory 507 for the eUICC device. The initial registration node IRN may thus control allocation of dummy identifications so that the same dummy identification is not allocated to two different wireless devices. On receipt of the dummy identification, the manufacturer may write/burn the dummy identification in wireless device memory 307. For example, the manufacturer may burn the dummy identification into a read only memory ROM portion of memory 307.
Operation 1a/1b. As discussed above, the eUICC wireless device is initially enabled with DCP dummy subscription before initiating provisioning with the first VPLMN. When the eUICC wireless device enters into a new country where MNO1 is a local operator the first VPLMN MN1, the eUICC wireless device attempts to attach to the local MNO1 network VPLMN MN1 (e.g., transmitting a CS domain attach request message to MNO1 MSC/VLR at operation 1a, or transmitting a PS domain attach request message to MNO1 SGSN at operation 1b) using the DCP dummy subscription information (that is included in the attach request message). The DCP dummy subscription information may include the dummy IMSI, dummy APN, dummy network access credentials, etc.
Operation 2a/2b. MNO1 MSC/VLR 201a-1 and/or SGSN 201b-1 may be configured to identify ranges of dummy IMSIs to determine when to route attach attempts (i.e., to route the attach request message) to initial registration node IRN. In a circuit switched embodiment, if the MSC 201a-1 determines that eUICC wireless device WD1 provided a dummy IMSI (in the range of known dummy IMSI numbers), MSC 201a-1 routes the attach/location update request message (also referred to as the location update message) to the DCP dummy HLR of the initial registration node at operation 2a. If the MSC 201a-1 determines that eUICC wireless device WD provided a real IMSI (outside the range of known dummy IMSI numbers), MSC 201a-1 routes the attach/location update request message (also referred to as the location update message) normally to VPLMN HLR 203-1. In a packet switched embodiment, if the SGSN 201b-1 determines that eUICC wireless device WD1 provided a dummy IMSI (in the range of known dummy IMSI numbers), SGSN 201b-1 routes the attach/location update request message (also referred to as the location update message) to the DCP dummy HLR of the initial registration node at operation 2b. If the MSC 201b-1 determines that eUICC wireless device WD1 provided a real IMSI (outside the range of known dummy IMSI numbers), MSC 201b-1 routes the attach/location update request normally to VPLMN HLR 203-1.
Operation 3. DCP dummy HLR of the initial registration node IRN is not a real HLR, because it may only implement special procedures according to some embodiments of inventive concepts. Once the location update request is received from MNO1 network MN1 (via operation 2a or 2b), the DCP dummy HLR may check with the local Policy Control function in the DCP dummy system IRN, to determine whether the location update will trigger a localization of operator subscription for the eUICC wireless device and re-provisioning a new local subscription to the eUICC wireless device. Policy Control function may make a decision based on predefined business rules/policies and the current PLMN (MCC/MNC) ID in the location update request (to know which country the device is located in and which MNO and which IMSI number it shall provision with).
Operation 4. If the Policy Control decision is true (i.e., the eUICC wireless device shall provision a new local MNO1 subscription for real traffic use), the policy control function will contact the DCP BSS system (an IT system) to handle the request to provision a new local MNO1 subscription. DCP BSS will select a local numbering (IMSI, MSISDN) from the local MNO1 numbering ranges.
Operation 5. DCP BSS will order and generate the new local MNO1 subscription (or select one existing subscription from the already pre-generated MNO1 subscriptions), provision the subscription into DCP MNO1 HLR 203-1, and also to DCP dummy system.
Operation 6. DCP dummy system will then form a subscription profile for the new MNO1 subscription to be downloaded to the eUICC wireless device WD, and the DCP dummy HLR then sends the new MNO1 subscription profile to eUICC wireless device WD to re-provision the eUICC wireless device WD with the new MNO1 subscription profile. DCP dummy HLR may have at least two ways to transport the new profile back to the eUICC wireless device WD, either via a data bearer through SGSN 201b-1 or via SMS/USSD bearer (SS7) through MSC 201a-1.
In case DCP dummy HLR has selected the SS7 bearer, the DCP dummy HLR can advance directly to Operation 12a below. According to some embodiments, if the initial attach is via MSC 201a-1 (circuit switched) at operation 1a, the new profile may be transmitted at operation 12a via MSC 201a-1.
In case DCP dummy HLR has selected the data bearer for transportation of new profile back to eUICC, the dummy HLR may first send the new profile data to the DCP dummy GGSN (DCP dummy GGSN and dummy HLR may coexist in one software node—DCP dummy system or server). Then it continues with the following steps. According to some embodiments, if the initial attach is via SGSN 201b-1 (packet switched) at operation 1b, the new profile may be transmitted via SGSN 201b-1 as discussed below with respect to operations 7b, 8b, 9b, 10b, 11b, and 12b.
Operation 7b. DCP dummy HLR may send a dummy “InsertSubscriberData” message to MNO1 SGSN 201b-1 in response to the location update request. The dummy “InsertSubscriberData” message is not a real “InsertSubscriberData” message as specified in the 3GPP standard or any real products, but only includes a few parameters that are used/required to set up the dummy PDP (Packet Data Protocol) context (also referred to as a PDP connection) between eUICC wireless device WD1 and the network, such as DCP dummy APN, and dummy IMSI.
Operation 8b. MNO1 SGSN 201b-1 may then send an attach accept message to eUICC wireless device WD1, indicating that the network has accepted the device attach request (of operation 1b), and also indicating that the network wants to set up a PDP context (also referred to as a PDP connection) with the eUICC wireless device (and/or SGSN 201b-1 may also send a SMS trigger to trigger the eUICC wireless device to set up PDP context). So when receiving the attach accept message (and/or the SMS trigger request), eUICC wireless device may start the PDP Context Creation Request towards the network, by using the Dummy IMSI and Dummy APN provided in the eUICC Dummy Subscription.
Operation 9b. MNO1 SGSN 201b-1 may receive the PDP context creation request, and may send the PDP context request towards DCP Dummy GGSN by querying the MNO1 DNS (Domain Name Server) which resolves the subscriber's dummy APN name to the DCP dummy GGSN IP address (MNO1 DNS may need to provision the DCP dummy GGSN IP address and dummy APN name in its own DNS record, or the MNO1 DNS can delegate the DNS query request to DCP DNS to resolve from the dummy APN name to the DCP dummy GGSN IP address).
Operation 10b. DCP dummy GGSN receives the PDP context request message from MNO1 SGSN 201b-1, and based on configured dummy APN, the Dummy GGSN may issue a request to the DCP dummy AAA (Radius) server to ask for a dummy IP address to be assigned to the eUICC wireless device. DCP dummy AAA server may maintain an IP address pool and allocate a dummy IP address based on the dummy IMSI and respond back with the dummy IP address assigned to the device through dummy GGSN and MNO1 SGSN.
Operation 11b. Once eUICC wireless device WD1 has been assigned dummy IP address, a GTP (GPRS Tunneling Protocol) tunnel may be established between MNO1 SGSN 201b-1 and DCP dummy GGSN, and the dummy PDP connection (dummy data bearer) may be established between eUICC wireless device and dummy GGSN.
Operation 12a. If providing subscription download using SS7 bearer (SMS/USSD) through MSC 201a-1, the MNO1 MSC/VLR 201a-1 receives the subscription profile data via SS7 signaling from DCP dummy HLR, and forwards the subscription profile data through SS7 signaling to eUICC wireless device WD.
Operation 12b. If providing subscription download over SGSN 201b-1, DCP dummy GGSN can push the new MNO1 profile data to the device, through the established dummy data bearer between dummy GGSN and eUICC wireless device (through SGSN 201b-1) per operation 12b, or eUICC wireless device can trigger to download the subscription data from the dummy network. Note that the only traffic allowed through DCP dummy GGSN is the eUICC subscription provisioning traffic (e.g., download & enable new subscription), and all other traffic may be blocked. This traffic restriction may be achieved by setting restrictions on the DCP dummy APN so that only traffic to and from DCP dummy system is allowed via this APN, and DCP Dummy System may only generate the subscription provisioning request (e.g. download/enable/disable/delete subscriptions).
Operation 13. When receiving the new MNO1 subscription profile from the network at eUICC wireless device, eUICC wireless device may save the new MNO1 subscription profile in memory 307 and enable the new MNO1 subscription profile and disable the DCP dummy profile, and make a new attachment to the MNO1 network using the new MNO1 subscription profile (including the new MNO1 IMSI). Even though the DCP dummy profile is disabled, eUICC wireless device may maintain the DCP dummy profile in memory 307.
Operation 14. The eUICC wireless device is now attached to the local MNO1 network using a local MNO1 subscription. The subscription provisioning process has now been completed.
According to some embodiments, the mobile network operator subscription profile may include some or all of the following information: IMSI (International Mobile Subscriber Identity), ICCID (Integrated Circuit Card Identifier), network access credentials, PIN (Personal Identification Number), PUK (Personal Unblocking Code), APN (Access Point Name), etc.
The DCP dummy subscription can also be used as fall back subscription for eUICC wireless device, in the event of eUICC wireless device connectivity failure at anytime and/or anywhere. The DCP dummy profile may be enabled automatically to always allow the eUICC wireless device to be attached and connected to the DCP dummy system, so that the eUICC wireless device can be remotely provisioned with new operational subscription from the network at any time if/when needed, using the same procedure as described above.
The DCP dummy subscription can also be used for eUICC wireless device fallback purposes during an entire lifecycle of the eUICC wireless device. For example, the DCP dummy subscription can be used as discussed above after factory testing is completed and factory testing subscription has been deleted from the eUICC wireless device and network but before any operational subscription has been provisioned & installed to eUICC wireless device. The eUICC wireless device can also fall back to the DCP dummy subscription to regain temporary connectivity from DCP dummy system for later remote provisioning of new operational subscription into the eUICC wireless device after an initial remote provisioning, without generating any/significant cost during this period and without having to ship the eUICC wireless device back to the manufacturer factory for re-provisioning (as may typically occur if the eUICC wireless device loses active connectivity).
According to embodiments disclosed herein, there may be no need to have a provisioning subscription in the eUICC wireless device that is known to a mobile network operator of a mobile network, and no need for mobile network operators to always keep a provisioning subscription active in the network (HLR). Use of the limited IMSI/MSISDN numbering resources, use of HLR space, and/or licensing cost may be reduced. Accordingly, connectivity costs for both operators and enterprise customers may be reduced.
Commercial value for DCP may thus be provided if all wireless devices (e.g., eUICC wireless devices) are provided with DCP Dummy subscription information (including a dummy IMSI) during manufacture or initial personalization. A eUICC wireless device can later be personalized and/or re-provisioned with a new local operator subscription anytime/anywhere using DCP dummy connectivity as discussed above. As discussed above, a partner (local) MNO may route the attach messages for those pre-defined DCP dummy IMSIs from their MSC/VLR and/or SGSN to DCP dummy HLR. The DCP may thus provide commercial value because all wireless devices (e.g., eUICC wireless devices) may be initially under control of the DCP platform through the DCP dummy SIM, and also, the new operational MNO subscriptions may be provisioned from the DCP platform (through dummy connectivity system) rather than DCP competitor platforms. Accordingly, the new MNO operational subscriptions may also be provisioned into the DCP platform rather than competitor platforms. DCP may thus gain more subscribers than today.
Moreover, by providing the that DCP dummy connection is always active at the DCP and that the dummy subscription information is always maintained at the eUICC wireless device, connectivity for the eUICC wireless device may always be provided using a DCP dummy connection as discussed above.

These computer program instructions may be provided to a processor circuit (also referred to as a processor) of a general purpose computer circuit, special purpose computer circuit, and/or other programmable data processing circuit to produce a machine, such that the instructions, which execute via the processor of the computer and/or other programmable data processing apparatus, transform and control transistors, values stored in memory locations, and other hardware components within such circuitry to implement the functions/acts specified in the block diagrams and/or flowchart block or blocks, and thereby create means (functionality) and/or structure for implementing the functions/acts specified in the block diagrams and/or flowchart block(s).
These computer program instructions may also be stored in a tangible computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instructions which implement the functions/acts specified in the block diagrams and/or flowchart block or blocks.
A tangible, non-transitory computer-readable medium may include an electronic, magnetic, optical, electromagnetic, or semiconductor data storage system, apparatus, or device. More specific examples of the computer-readable medium would include the following: a portable computer diskette, a random access memory (RAM) circuit, a read-only memory (ROM) circuit, an erasable programmable read-only memory (EPROM or Flash memory) circuit, a portable compact disc read-only memory (CD-ROM), and a portable digital video disc read-only memory (DVD/BlueRay).
The computer program instructions may also be loaded onto a computer and/or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer and/or other programmable apparatus to produce a computer-implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions/acts specified in the block diagrams and/or flowchart block or blocks. Accordingly, embodiments of present inventive concepts may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.) that runs on a processor such as a digital signal processor, which may collectively be referred to as “circuitry,” “a module” or variants thereof.
It should also be noted that in some alternate implementations, the functions/acts noted in the blocks may occur out of the order noted in the flowcharts. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Moreover, the functionality of a given block of the flowcharts and/or block diagrams may be separated into multiple blocks and/or the functionality of two or more blocks of the flowcharts and/or block diagrams may be at least partially integrated. Finally, other blocks may be added/inserted between the blocks that are illustrated. Moreover, although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.
Many different embodiments have been disclosed herein, in connection with the above description and the drawings. It will be understood that it would be unduly repetitious and obfuscating to literally describe and illustrate every combination and subcombination of these embodiments. Accordingly, the present specification, including the drawings, shall be construed to constitute a complete written description of various example combinations and subcombinations of embodiments and of the manner and process of making and using them, and shall support claims to any such combination or subcombination.
Other network elements, communication devices and/or methods according to embodiments of inventive concepts will be or become apparent to one with skill in the art upon review of the present drawings and description. It is intended that all such additional network elements, devices, and/or methods be included within this description, be within the scope of the present inventive concepts. Moreover, it is intended that all embodiments disclosed herein can be implemented separately or combined in any way and/or combination. Accordingly, the above disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the spirit and scope of present inventive concepts. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims, and shall not be restricted or limited by the foregoing detailed description.
This application claims the benefit of U.S. provisional Patent Application No. 62/090,135, filed Dec. 10, 2014, the disclosure and content of which is incorporated by reference herein in its entirety.
