1. Field
Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to concurrent communication services during other active wireless communication sessions.
2. Background
Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, etc. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Examples of such multiple-access networks include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, and Single-Carrier FDMA (SC-FDMA) networks.
A wireless communication network may include a number of base stations that can support communication for a number of user equipments (UEs), also referred to as mobile entities. A UE may communicate with a base station via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. As used herein, a “base station” means an eNode B (eNB), a Node B, a Home Node B, or similar network component of a wireless communications system.
The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) represents a major advance in cellular technology as an evolution of Global System for Mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS). The LTE physical layer (PHY) provides a highly efficient manner to convey both data and control information between base stations, such as an evolved Node Bs (eNBs), and mobile entities, such as UEs. In prior applications, a method for facilitating high bandwidth communication for multimedia has been single frequency network (SFN) operation. SFNs utilize radio transmitters, such as, for example, eNBs, to communicate with subscriber UEs. In unicast operation, each eNB is controlled so as to transmit signals carrying information directed to one or more particular subscriber UEs. The specificity of unicast signaling enables person-to-person services such as, for example, voice calling, text messaging, or video calling.
Recent LTE versions support eMBMS in the LTE air interface to provide the video streaming and file download broadcast delivery. For example, video streaming service is expected to be transported by the DASH (Dynamic Adaptive Streaming using HTTP) protocol over FLUTE (File Delivery over Unidirectional Transport) as defined in IETF RFC 3926 over UDP/IP packets. File download service is transported by FLUTE over UDP/IP protocols. Both high layers over IP are processed by the LTE broadcast channels in PHY and L2 (including MAC and RLC layers). However, such transport includes multiple inefficiencies which are not currently addressed in the communications industry.
Among these inefficiencies is an inability to intelligently send and receive concurrent communication sessions during an active communication session. For example, commercial mobile alert system (CMAS) and Earthquake and Tsunami warning system (ETWS) are features that help service providers, who choose to participate, to send emergency alerts users who have ETWS/CMAS capable handsets. In current ETWS/CMAS capable handsets, there are no systems or methods that can determine the importance of an alert, while the UE is streaming active eMBMS content. Further, there are no systems or methods that can choose from various ways of conveying the emergency alert and content to a user, while the UE is streaming active eMBMS content.
Various aspects of the present disclosure are directed to a method for wireless communication, which may include receiving streaming communication content at a mobile device during an active communication session. The example method may further comprise presenting the streaming communication content at the mobile device. Further still, the example method may receive an indication, at the mobile device during the active communication session, that a concurrent communication service is available and present notification of the available concurrent communication service at the mobile device while concurrently streaming the communication content.
In further aspects of the present disclosure, a method for wireless communication may include streaming communication content, by user equipment (UE), and receiving, from a network service, concurrent content, wherein the receiving is concurrent with the streaming. Moreover, the example method may identify, while concurrently streaming the streaming content, a category associated with the concurrent content. Based on the identifying, the method may determine how to present the concurrent content to a user, wherein the identifying is concurrent with streaming the streaming content. Based on the determining, the example method may present the concurrent content to a user of the UE.
An example wireless device for wireless communication according to additional aspects of the present disclosure may include a computer processor that receives streaming content. The example wireless device may also have a display that presents the streaming content. The computer processor may also receive concurrent content, and the concurrent content may be received concurrently with the streaming content. Further the concurrent content may comprises an indication of a category associated with the concurrent content. The computer processor may also identify the category, and based on the category, the computer processor may determine how to present the concurrent content to a user. In this example, the display may present the concurrent content according to the computer processor's determination, and the display may also concurrently stream the streaming content and present the concurrent content.
Further aspects of the present disclosure are directed to a wireless communication system comprises means for receiving streaming content, and means for receiving concurrent content, wherein the receiving is concurrent with the receiving the streaming content. Aspects of a wireless communication system also include means for identifying, while concurrently receiving the streaming content, a category associated with the concurrent content. Based on the identifying, the example wireless communication system may include means for determining how to present the concurrent content to a user, wherein the identifying is concurrent with the streaming content. Further, based on the determining, the example wireless communication system may include means for presenting the concurrent content to a user of the UE.
An example non-transitory computer-readable medium according to additional aspects of the present disclosure is also disclosed herein having program code stored thereon, wherein the program code, when executed by a computer, causes the computer to present streaming content. The program code, when executed also causes the computer to receive concurrent content, wherein the receiving is concurrent with the streaming. The computer is further caused to identify, while concurrently streaming the streaming content, a category associated with the concurrent content. Based on the identifying, the computer is caused to determine how to present the concurrent content to a user, wherein the determination is determined concurrently with streaming the streaming content. Based on the determining, the computer is caused to present the concurrent content to a user of the UE.

However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
The techniques described herein may be used for various wireless communication networks such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms “network” and “system” are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), CDMA2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA network may implement a radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). CDMA2000 and UMB are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). The techniques described herein may be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, certain aspects of the techniques are described below for LTE, and LTE terminology is used in much of the description below.
An eNB may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or other types of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a pico cell may be referred to as a pico eNB. An eNB for a femto cell may be referred to as a femto eNB or a home eNB (HNB). In the example shown in
The wireless network 100 may also include relay stations 110r. A relay station is a station that receives a transmission of data and/or other information from an upstream station (e.g., an eNB or a UE) and sends a transmission of the data and/or other information to a downstream station (e.g., a UE or an eNB). A relay station may also be a UE that relays transmissions for other UEs. In the example shown in
The wireless network 100 may be a heterogeneous network that includes eNBs of different types, e.g., macro eNBs, pico eNBs, femto eNBs, relays, etc. These different types of eNBs may have different transmit power levels, different coverage areas, and different impact on interference in the wireless network 100. For example, macro eNBs may have a high transmit power level (e.g., 20 Watts) whereas pico eNBs, femto eNBs and relays may have a lower transmit power level (e.g., 1 Watt).
The wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, the eNBs may have similar frame timing, and transmissions from different eNBs may be approximately aligned in time. For asynchronous operation, the eNBs may have different frame timing, and transmissions from different eNBs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.
A network controller 130 may couple to a set of eNBs and provide coordination and control for these eNBs. The network controller 130 may communicate with the eNBs 110 via a backhaul. The eNBs 110 may also communicate with one another, e.g., directly or indirectly via wireless or wireline backhaul.
The UEs 120 may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as a terminal, a mobile station, a subscriber unit, a station, etc. A UE may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, or other mobile entities. A UE may be able to communicate with macro eNBs, pico eNBs, femto eNBs, relays, or other network entities. In
LTE utilizes orthogonal frequency division multiplexing (OFDM) on the downlink and single-carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM partition the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier may be modulated with data. In general, modulation symbols are sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may be dependent on the system bandwidth. For example, K may be equal to 128, 256, 512, 1024 or 2048 for system bandwidth of 1.25, 2.5, 5, 10 or 20 megahertz (MHz), respectively. The system bandwidth may also be partitioned into subbands. For example, a subband may cover 1.08 MHz, and there may be 1, 2, 4, 8 or 16 subbands for system bandwidth of 1.25, 2.5, 5, 10 or 20 MHz, respectively.
In LTE, an eNB may send a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) for each cell in the eNB. The primary and secondary synchronization signals may be sent in symbol periods 6 and 5, respectively, in each of subframes 0 and 5 of each radio frame with the normal cyclic prefix, as shown in
The eNB may send a Physical Control Format Indicator Channel (PCFICH) in only a portion of the first symbol period of each subframe, although depicted in the entire first symbol period in
The eNB may send the PSS, SSS and PBCH in the center 1.08 MHz of the system bandwidth used by the eNB. The eNB may send the PCFICH and PHICH across the entire system bandwidth in each symbol period in which these channels are sent. The eNB may send the PDCCH to groups of UEs in certain portions of the system bandwidth. The eNB may send the PDSCH to specific UEs in specific portions of the system bandwidth. The eNB may send the PSS, SSS, PBCH, PCFICH and PHICH in a broadcast manner to all UEs, may send the PDCCH in a unicast manner to specific UEs, and may also send the PDSCH in a unicast manner to specific UEs.
A number of resource elements may be available in each symbol period. Each resource element may cover one subcarrier in one symbol period and may be used to send one modulation symbol, which may be a real or complex value. Resource elements not used for a reference signal in each symbol period may be arranged into resource element groups (REGs). Each REG may include four resource elements in one symbol period. The PCFICH may occupy four REGs, which may be spaced approximately equally across frequency, in symbol period 0. The PHICH may occupy three REGs, which may be spread across frequency, in one or more configurable symbol periods. For example, the three REGs for the PHICH may all belong in symbol period 0 or may be spread in symbol periods 0, 1 and 2. The PDCCH may occupy 9, 18, 32 or 64 REGs, which may be selected from the available REGs, in the first M symbol periods. Only certain combinations of REGs may be allowed for the PDCCH.
A UE may know the specific REGs used for the PHICH and the PCFICH. The UE may search different combinations of REGs for the PDCCH. The number of combinations to search is typically less than the number of allowed combinations for the PDCCH. An eNB may send the PDCCH to the UE in any of the combinations that the UE will search.
A UE may be within the coverage of multiple eNBs. One of these eNBs may be selected to serve the UE. The serving eNB may be selected based on various criteria such as received power, path loss, signal-to-noise ratio (SNR), etc.
At the base station 110, a transmit processor 320 may receive data from a data source 312 and control information from a controller/processor 340. The control information may be for the PBCH, PCFICH, PHICH, PDCCH, etc. The data may be for the PDSCH, etc. The processor 320 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The processor 320 may also generate reference symbols, e.g., for the PSS, SSS, and cell-specific reference signal. A transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, and/or the reference symbols, if applicable, and may provide output symbol streams to the modulators (MODs) 332a through 332t. Each modulator 332 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 332 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 332a through 332t may be transmitted via the antennas 334a through 334t, respectively.
At the UE 120, the antennas 352a through 352r may receive the downlink signals from the base station 110 and may provide received signals to the demodulators (DEMODs) 354a through 354r, respectively. Each demodulator 354 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 354 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 356 may obtain received symbols from all the demodulators 354a through 354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 360, and provide decoded control information to a controller/processor 380.
On the uplink, at the UE 120, a transmit processor 364 may receive and process data (e.g., for the PUSCH) from a data source 362 and control information (e.g., for the PUCCH) from the controller/processor 380. The processor 364 may also generate reference symbols for a reference signal. The symbols from the transmit processor 364 may be precoded by a TX MIMO processor 366 if applicable, further processed by the modulators 354a through 354r (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the base station 110, the uplink signals from the UE 120 may be received by the antennas 334, processed by the demodulators 332, detected by a MIMO detector 336 if applicable, and further processed by a receive processor 338 to obtain decoded data and control information sent by the UE 120. The processor 338 may provide the decoded data to a data sink 339 and the decoded control information to the controller/processor 340.
The controllers/processors 340 and 380 may direct the operation at the base station 110 and the UE 120, respectively. The processor 340 and/or other processors and modules at the base station 110 may perform or direct the execution of various processes for the techniques described herein. The processor 380 and/or other processors and modules at the UE 120 may also perform or direct the execution of the functional blocks illustrated in
In one configuration, the UE 120 for wireless communication includes means for detecting interference from an interfering base station during a connection mode of the UE, means for selecting a yielded resource of the interfering base station, means for obtaining an error rate of a physical downlink control channel on the yielded resource, and means, executable in response to the error rate exceeding a predetermined level, for declaring a radio link failure. In one aspect, the aforementioned means may be the processor(s), the controller/processor 380, the memory 382, the receive processor 358, the MIMO detector 356, the demodulators 354a, and the antennas 352a configured to perform the functions recited by the aforementioned means. In another aspect, the aforementioned means may be a module or any apparatus configured to perform the functions recited by the aforementioned means.
eMBMS and Unicast Signaling in Single Frequency Networks:
One technique to facilitate high bandwidth communication for multimedia has been single frequency network (SFN) operation. Particularly, Multimedia Broadcast Multicast Service (MBMS) and MBMS for LTE, also known as evolved MBMS (eMBMS) (including, for example, what has recently come to be known as multimedia broadcast single frequency network (MBSFN) in the LTE context), can utilize such SFN operation. SFNs utilize radio transmitters, such as, for example, eNBs, to communicate with subscriber UEs. Groups of eNBs can transmit information in a synchronized manner, so that signals reinforce one another rather than interfere with each other. In the context of eMBMS, the shared content is transmitted from multiple eNB's of a LTE network to multiple UEs. Therefore, within a given eMBMS area, a UE may receive eMBMS signals from any eNB(s) within radio range as part of the eMBMS service area or MBSFN area. However, to decode the eMBMS signal each UE receives Multicast Control Channel (MCCH) information from a serving eNB over a non-eMBMS channel. MCCH information changes from time to time and notification of changes is provided through another non-eMBMS channel, the PDCCH. Therefore, to decode eMBMS signals within a particular eMBMS area, each UE is served MCCH and PDCCH signals by one of the eNBs in the area.
In accordance with aspects of the subject of this disclosure, there is provided a wireless network (e.g., a 3GPP network) having features relating to single carrier optimization for eMBMS. eMBMS provides an efficient manner to transmit shared content from an LTE network to multiple mobile entities, such as, for example, UEs.
With respect a physical layer (PHY) of eMBMS for LTE Frequency Division Duplex (FDD), the channel structure may comprise time division multiplexing (TDM) resource partitioning between eMBMS and unicast transmissions on mixed carriers, thereby allowing flexible and dynamic spectrum utilization. Currently, a subset of subframes (up to 60%), known as multimedia broadcast single frequency network (MBSFN) subframes, can be reserved for eMBMS transmission. As such current eMBMS design allows at most six out of ten subframes for eMBMS.
An example of subframe allocation for eMBMS is shown in
With continued reference to
eMBMS Service Areas:
eMBMS System Components and Functions:
The system 600 may include an MBMS Gate Way (MBMS GW) 616. The MBMS GW 616 controls Internet Protocol (IP) multicast distribution of MBMS user plane data to eNodeBs 604 via an M1 interface; one eNB 604 of many possible eNBs is shown. In addition, the MBMS GW controls IP multicast distribution of MBMS user plane data to UTRAN Radio Network Controllers (RNCs) 620 via an M1 interface; one UTRAN RNC 620 of many possible RNCs is shown. The M1 interface is associated to MBMS data (user plane) and makes use of IP for delivery of data packets. The eNB 604 may provide MBMS content to a user equipment (UE)/mobile entity 602 via an E-UTRAN Uu interface. The RNC 620 may provide MBMS content to a UE mobile entity 622 via a Uu interface. The MBMS GW 616 may further perform MBMS Session Control Signaling, for example MBMS session start and session stop, via the Mobility Management Entity (MME) 608 and Sm interface. The MBMS GW 616 may further provide an interface for entities using MBMS bearers through the SG-mb (user plane) reference point, and provide an interface for entities using MBMS bearers through the SGi-mb (control plane) reference point. The SG-mb Interface carries MBMS bearer service specific signaling. The SGi-mb interface is a user plane interface for MBMS data delivery. MBMS data delivery may be performed by IP unicast transmission, which may be a default mode, or by IP multicasting. The MBMS GW 616 may provide a control plane function for MBMS over UTRAN via a Serving General Packet Radio Service Support Node (SGSN) 618 and the Sn/Iu interfaces.
The system 600 may further include a Multicast Coordinating Entity (MCE) 606. The MCE 606 may perform an admission control function form MBMS content, and allocate time and frequency radio resources used by all eNBs in the MBSFN area for multi-cell MBMS transmissions using MBSFN operation. The MCE 606 may determine a radio configuration for an MBSFN Area, such as, for example, the modulation and coding scheme. The MCE 606 may schedules and control user plane transmission of MBMS content, and manage eMBMS service multiplexing, by determining which services are to be multiplexed in which Multicast Channel (MCH). The MCE 606 may participate in MBMS Session Control Signaling with the MME 608 through an M3 interface, and may provide a control plane interface M2 with the eNB 604.
The system 600 may further include a Broadcast-Multicast Service Center (BM-SC) 612 in communication with a content provider server 614. The BM-SC 612 may handle intake of multicast content from one or more sources such as the content provider 614, and provide other higher-level management functions as described below. These functions may include, for example, a membership function, including authorization and initiation of MBMS services for an identified UE. The BM-SC 612 may further perform MBMS session and transmission functions, scheduling of live broadcasts, and delivery, including MBMS and associated delivery functions. The BM-SC 612 may further provide service advertisement and description, such as advertising content available for multicast. A separate Packet Data Protocol (PDP) context may be used to carry control messages between a UE and BM-SC 612. The BM-SC 612 may further provide security functions such as key management, manage charging of content providers according to parameters such as data volume and QoS, provide content synchronization for MBMS in UTRAN and in E-UTRAN for broadcast mode, and provide header compression for MBSFN data in UTRAN. The BM-SC 612 may indicate session start, update and stop to the MBMS-GW 616 including session attributes such as QoS and MBMS service area.
The system 600 may further include a Multicast Management Entity (MME) 608 in communication with the MCE 606 and MBMS-GW 608. The MME 600 may provide a control plane function for MBMS over E-UTRAN. In addition, the MME may provide the eNB 604, 620 with multicast related information defined by the MBMS-GW 616. An Sm interface between the MME 608 and the MBMS-GW 616 may be used to carry MBMS control signaling, for example, session start and stop signals.
The system 600 may further include a Packet Data Network (PDN) Gate Way (GW) 610, sometimes abbreviated as a P-GW. The P-GW 610 may provide an Evolved Packet System (EPS) bearer between the UE 602 and BM-SC 612 for signaling and/or user data. As such, the P-GW may receive Uniform Resource Locator (URL) based requests originating from UEs in association with IP addresses assigned to the UEs. The BM-SC 612 may also be linked to one or more content providers via the P-GW 610, which may communicate with the BM-SC 612 via an IP interface.
Presently, during an active streaming communication session supported by the systems and methods described above, there is currently no elegant manner to begin a concurrent communication service or a notification thereof. For example, if a user is viewing streaming content on a mobile device, whether through unicast, broadcast, or multicast, any new concurrent services will break the current session and leave the user with a negative user experience. Thus, better handling of the beginning and notification of concurrent communications (for example service alerts) during an already active communication session is desired.
The already active communication session (e.g., the original communication service) can be any one of a unicast, broadcast, or multicast. An exemplary original communication service is streaming eMBMS content. Concurrent communication services are communications whose transmission may have begun after the original communication service started but nonetheless are being transmitted concurrently with the original communication service. A concurrent communication service may be of the same type of communication as the original communication (e.g., both communications may be an eMBMS, both may be a voice communications, both may be streaming audio or video communications, both may be streaming multimedia, etc.). Additionally or alternative, a concurrent communication service may be a different type of communication as compared to the original communication (e.g., the original communication may be streaming video while the concurrent communication may be an eMBMS, the original communication may be streaming multimedia while the concurrent communication may be streaming audio content).
One example of a concurrent communication is a Commercial Mobile Alert System (CMAS) communication and/or Earthquake and Tsunami Warning System (ETWS) communication. CMAS and ETWS are emergency communication systems that send emergency communications, for example, service alerts. It should be noted that other servicing entities are able to send alerts to participants that desire them, for example a service alert system operable to inform employees about company alerts (e.g., inclement weather causing an office to be closed for an amount of time). Service alerts from CMAS, ETWS, and others help service providers (who choose to participate) send emergency alerts to their users who have capable handsets. CMAS service alerts may be concurrently transmitted on SystemInformationBlock (SIB) 12, ETWS service alerts may be concurrently transmitted on SIB 11, and other service alerts could be established to transmit on other SIBs as is desired.
Concurrent communication services may be categorized, ranked, prioritized, classified, typed, and/or the like. For example, a emergency service alerts in CMAS may be categorized into one of three categories: (1) Presidential Alerts, including alert message issued by the President for local, regional, or national emergencies and may be considered the a highest priority alert; (2) Imminent Threat Alerts, including notification of emergency conditions, such as hurricanes or tornadoes, where there is an imminent threat to life or property and some immediate responsive action should be taken; and (3) Child Abduction Emergency/AMBER Alerts, including alerts related to missing or endangered children (and/or adults) due to an abduction or runaway situation. In another example, a service alert may be ranked into one of several categories: for example, Low, Intermediary, High, and Highest. It should be noted that any number of rankings and categories may be established as is desired. Further, the ranking may be a threshold wherein a service alert comprises a value (for example), and the value is compared to a threshold to determine the service alert's ranking (e.g., if x≧4, then the service alert is in the Imminent category, if x≧4, then the service alert is of type B, if x≧4, then the service type is Intermediary, etc.). Emergency communications as concurrent services may be categorized in this manner, while non-emergency services that become concurrent services may have other categories or types. Any number of categories, ranks, priorities, classifications, thresholds, types, and/or the like, can be used as is desired for emergency communications and/or non-emergency communications transmitted as concurrent services.
Classifying, ranking, categorizing, prioritizing, typing etc. concurrent communications helps a UE intelligently handle concurrent communications received during an active communication service because the UE receiving the concurrent communication can identify the classification, ranking, category, priority, type, etc. of the concurrent communication and intelligently present the concurrent communication, or notification thereof, to a user based on the identified classification, ranking, category, priority, type, etc. For example, a CMAS/ETWS alert can be intelligently conveyed to a user during active streaming of eMBMS content, wherein the manner of conveyance is based on the identified classification of the CMAS/ETWS alert.
After the network entity receives the concurrent communication service, one or more processors (e.g. MBMS GW 616) of the network entity will transmit the concurrent communication service to all appropriate UEs (e.g. UE 602 and 622) via eNB 604 and/or UTRAN 620. The transmission may be a separate transmission comprising some or all of the originally received transmission of the concurrent communication service, but could also be a relay of the originally received transmission of the concurrent communication service. Appropriate UEs may be those UEs which are identified by the content providing entity 614 as being appropriate to receive the concurrent communication service. The concurrent communication service may include destination information that identifies the appropriate UEs to receive the concurrent communication session. The network provider may have a list of the appropriate UEs or otherwise be able to identify the appropriate UEs. The appropriate UEs may be identifiable based on their geographical location, their subscription to a service, their recent historical activity, their long term historical activity, or any combination thereof. The network entity transmits the concurrent communication service to one or more UE concurrently with transmitting the original communication service to the one or more UE, block 703.
The concurrent communication service and/or notification thereof may be categorized, ranked, prioritized, classified, typed, and/or the like, as discussed above. For example, the concurrent communication service may be categorized as Imminent. The UE may be operable to identify the concurrent communication service's category from the data the UE received from the network entity, block 803. For example, the UE may identify the concurrent communication service as being Imminent. Based on the concurrent communication service's identified category, the UE may determine how to present the concurrent communication service to the UE user, block 804. For example, based on the UE's identification of the concurrent communication service as being Imminent, the UE determines how to present the concurrent communication service to the user. Based on the determination of how to present the concurrent communication service to the user, the UE presents the concurrent communication service to the user in accordance with the determination, block 805. For example, the UE determines that Imminent concurrent communication services (or notifications thereof) are presented in a particular manner, and then presents the concurrent communication service (or notification thereof) in that particular manner.
Additionally and/or alternative, ID Logic 1006 may be operable to independently identify the category, rank, priority, classification, type, etc. of the concurrent communication service based on information other than identity data included in the concurrent communication service. Such an independent identification of the category, rank, priority, classification, type, etc. may be useful for concurrent communication services which lack identity data. Independent identification may also be useful to verify that the data included in a concurrent communication service accurately identified by the identification data included in the concurrent communication service. The independent identification may also be useful to verify and/or authenticate the source from which the concurrent communication service originated and/or was received.
Based on the identifying determination, UE 1000 will determine how to present the concurrent communication service to the user, as explained in blocks 804 and 904. For example, in selected alternative aspects of the present disclosure, UE 1000 may utilize optional table 1008 to determine the proper presentation of the concurrent communication service. Table 1008, which may be stored in memory 1004, is disclosed in the functionality provided in block 904 of
Once UE 1000 determines how to present the concurrent communication service to the user, the processor 1003 interfaces with the display interface 1002, to display the concurrent communication service to the user on display 1001, while concurrently streaming the streaming content 1007, as discussed in blocks 805 and 905.
There may be several ways for a UE to present a concurrent communication service to the user. The number and ways of presenting concurrent communication services to a user may change from time to time as is desired by a user, a network entity, a content providing entity, and/or any combination thereof. Examples of manners of presenting a concurrent communication service are described below.
In examples where the pop-up 1009 is a notification of an available concurrent communication service, the UE is operable to receive user input indicating the user's desire to be directed to the available concurrent communication service. For example, pop-up 1009 may include a selection option 1010 indicating that the user desires the UE to present the available concurrent communication service on display 1001. If the user selects selection option 1010, then the UE will present the available concurrent communication service on display 1001. As a user touches selection option 1010 on display 1001, display interface 1002 operates to detect the touch and convert the touch data into a signal that processor 1003 may use to display the concurrent communication to the user. Additionally and/or alternatively, if the pop-up 1009 is the concurrent communication service, UE may be operable to receive user input indicating that the user desires to see additional information about the event described in the concurrent communication service. For example, pop-up 1009 may include a selection option 1010 indicating that the user desires the UE to present additional information regarding the event featured in the concurrent communication service on display 1001. If the user, through user input, indicates the desire to see additional information regarding the event featured in the concurrent communication service, then the UE will present additional information regarding the event featured in the concurrent communication service on display 1001.
In examples where the pop-up 1009 is a notification of an available concurrent communication service, the UE is operable to receive user input indicating the user's desire to be directed to the available concurrent communication service. For example, pop-up 1009 may include a selection option 1011 indicating that the user desires the UE stop streaming the streaming content (e.g., the original streaming communication) and begin presenting the available concurrent communication on display 1001. If the user selects selection option 1011, the signal detected by display interface 1002 may be used by processor 1003 for the UE to begin presenting the available concurrent communication service. The original communication may be stopped while the available concurrent communication service is presented, but alternatively, the original communication may continue to stream and/or be displayed while the available concurrent communication service is presented.
Additionally and/or alternatively, if the pop-up 1009 is the concurrent communication service (rather than a notification thereof), UE may be operable to receive user input indicating that the user desires to see additional information about the event described in the concurrent communication service. For example, pop-up 1009 may include a selection option 1011 indicating that the user desires the UE to present additional information regarding the event featured in the concurrent communication service on display 1001. If the user makes such an indication to the UE, then the UE displays the additional information.
The UE is also operable to receive user input indicating that the user does not desire to view the concurrent communication service (or notification thereof). For example, if pop-up 1009 is the concurrent communication service or a notification of an available a concurrent communication service, pop-up 1009 may include a selection option 1010, which when selected, indicates that the user does not desire to stop streaming the original communication. If the user selects selection option 1010, the UE stops displaying the pop-up 1009 and streaming content 1007 is brought back to the foreground of display 1001.
Some or all of any pop-up image discussed herein may be translucent if desired allowing the background to be viewed without substantial obstruction. Additionally or alternatively, some or all of any pop-up image discussed herein may be opaque if desired thereby obscuring the background content.
The concurrent communication service may be presented as a marquee 1013 or banner which displays at or near the top, bottom, or side of the display 1001. The concurrent communication service message 1014 could display as a split screen presenting on any portion of the screen 1001 as is desired by a user, a network provider, provider entity, and/or any combination thereof. Further, the manner and extent of screen splitting can be contingent on the concurrent communication service's category, rank, priority, classification, type, and/or the like.
Any of the above described pop-up images, marquees, and/or banners may present the user with options. For example, the user may be offered the option to turn off the presenting of the concurrent communication service. If the UE receives input from the user indicating the desire to turn off the presentation of the concurrent communication service, then the UE may turn off the presenting of the concurrent communication service. If the original communication service had been paused when the concurrent communication service was displayed, then the UE may resume presenting of the original communication service. If the original communication service had been moved to the background of the display when the concurrent communication service was displayed, then the UE may resume presenting the original communication service in the foreground of the display. If the original communication service had been moved to a smaller portion of the display when the concurrent communication service was displayed, then the UE may resume presenting the original communication service in the portion of the display within which it is was originally being presented.
Another option that may be presented to the user allows the user to turn off the original communication service. If the UE receives input indicating that the user desires the original communication service be turned off, then the UE can stop presenting the original communication service. Additionally, if desired, the UE can stop streaming the original communication service. When turning off the original communication service, the UE may continue to present the concurrent communication service. If the concurrent communication service is being displayed in a portion of the user interface (e.g., as a pop-up or marquee), the UE may adjust the presentation of the concurrent communication service such that a larger portion (or entire portion) of the display presents the concurrent communication. Further, if the concurrent communication is translucent, the UE may adjust the presentation of the concurrent communication service such that the concurrent communication service is no longer translucent.
In examples, the concurrent communication may be a service alert comprising a concurrent communication service but could also be a service alert comprising notification of an available concurrent communication service. If the service alert comprises the concurrent communication service, then the concurrent communication may present information to the user which alerts the user to a situation. For example, the service alert may provide information about an imitate tornado and give instructions regarding how to handle the situation. The service alert may be text, streaming audio, streaming video, streaming multimedia content, unicast, multicast, eMBMS, and/or the like. The service alert may include an option for the user to receive additional information about the service alert. The service alert may include a link which takes the user to another communication including further information.
If service alert is a notification of an available concurrent communication service, then the notification may present an option for the user to receive the available concurrent communication service. For example, the notification may be included in a SIB, which typically supports a limited about of data, while the available concurrent communication service may be streaming on a different channel (as compared to the SIB on which the notification was received), and when the UE receives user input that the user desires to stream the available concurrent communication service on the different channel, the UE will begin streaming and presenting the available concurrent communication service on the different channel.
