“SYSTEM AND METHOD FOR POINT-TO-POINT AUTHORIZATION THROUGH STRATUM NON-ACCESS PROCEDURES”. This application claims priority, in accordance with 35 U.S.C.
S$119(e), for the provisional U.S.
Serial No. 61/431 765, filed January 11, 2011, which is incorporated herein by reference in its entirety. Field of the Invention The present application relates generally to wireless communications and more specifically to the authorization of wireless apparatus for point-to-point communication.
Description of the Prior Art The Long Term Evolution (LTE) of the 3rd Generation Partnerships Project (3GP) represents a major advance in cellular technology and is the next step forward in 3G cellular services as a natural evolution of the Global System for Mobile communications ( GSM) and the Universal Mobile Telecommunications System (UMTS). The physical layer (PHY) LTE is a highly efficient means of transmitting both data and control information between an evolved NodeB (eNB) and mobile entities such as, for example, access terminals (ATs) or user equipment (UE) . PHY LTE employs some advanced technologies that are new to mobile applications.
They include Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input and Multiple Output (MIMO) data transmission. In addition, PHY LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) on the downlink (DL) and Single Carrier Frequency Division Multiple Access (SC-FDMA) on the uplink (UL). OFDMA allows data to be directed to or from multiple users on a sub-carrier by sub-carrier basis for a specified number of symbol periods.
Examples of older wireless communication systems widely deployed to provide various types of communication content, such as voice and data, include Code Division Multiple Access (CDMA) systems, including CDMAZ000, Broadband CDMA, Global System for Mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS). These wireless communication systems and LTE systems generally use different radio access technologies (RATs) and communication protocols, operate in different frequency bands, provide different Quality of Service (Q0S) and offer different types of service and applications to users of the systems.
In a direct wireless connection, a first mobile entity transmits a wireless signal directly to a second mobile entity, which receives and processes the wireless signal.
Examples of direct wireless connections include connections from a mobile entity to NOSB on LTE or other wireless communication protocols, Or point-to-point (P2P) connections between mobile entities as used in non-cellular protocols such as WiFi Direct or Bluetooth.
Wireless cellular communication systems typically do not include direct connections between mobile entities.
Instead, mobile entities typically communicate indirectly with each other through one or more NODES and associated network infrastructure.
In this context, there is a need to effectively manage the authorization of mobile entities for P2P communication.
Summary of the Invention In a cellular wireless communication system, it may be desirable to implement P2P communications within a system that also uses cellular communication between base stations (e.g., NodesBs) and mobile entities. As used herein, "P2P" refers to communication or signaling between peer mobile entities, in contrast to "cellular", which refers to wireless communications between mobile entities and base stations. P2P, as used herein, excludes communications between peer base stations or other peer nodes of the wireless communication system. P2P communications, as defined above, may sometimes be referred to as device-to-device, abbreviated as “D2D”. Mobile entities as a group are distinguished from base stations and can be distinguished from base stations by various factors known in the art; for example, a base station typically includes a return transport channel connection to the core network and support for related interface components, while mobile entities lack such components and are generally portable. In other respects, mobile entities may include components also found in base stations, for example, processor, memory AND transceiver components.
When a wireless communication system that supports both cellular and P2P communications in one or more overlapping areas, issues related to interference between cellular and P2P wireless signaling in an area can arise. Several control methodologies can be used to coordinate P2P and cellular signaling in an area in order to minimize interference between these communication nodes. One aspect of such control methodologies may include authorizing a mobile entity to initiate a communication session in which the mobile entity operates in a P2P mode with another mobile entity. Such authorization may be referred to here as P2P authorization. It should be understood that, unless authorized to operate in P2P mode, the mobile entity may generally operate in a cellular mode. P2P authorization can be performed by one or more entities of a wireless communication system, in cooperation with other entities of the system.
In one aspect, the first method for point-to-point (P2P) authorization by a mobile entity may include receiving a message to accept P2P authorization from a management entity through a non-access layer (NAS).

Detailed Description of the Invention Several embodiments are now described with reference to the figures, in which the same reference numerals are used to refer to the same elements throughout. In the following description, for the purpose of explanation, numerous specific details are set up in order to obtain a complete understanding of one or more aspects. It may be evident, however, that such modality(s) can be put into practice without these specific details. In other cases, well-known structures and apparatus are shown in block diagram form in order to facilitate the description of one or more modalities.
The techniques described herein can be used in various wireless communication networks, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access networks ( FDMA), Orthogonal FDMA networks (OFDMA), Single Carrier FDMA networks, etc. The terms “networks” and “systems” are often used interchangeably. A CDMA network can implement a radio technology such as Universal Terrestrial Radio Access (UTRAj, CDMAZ000 or other radio technologies. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR) The CDMA2000 covers 1S-2000, I1IS-95 and I1IS-856 standards A TDMA network can implement a radio technology such as Global System for Mobile Communications (GSM) An OFDMA network can implement a radio technology such as Evolved UTRA (E-UTRA), TEEE 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDMO, etc. UTRA, E-UTRA and GSM are part of the Universal Mobile Telecommunications System (UMTS). Long Term Evolution (LTE) is a version of UMTS that uses E-UTRA UTRA, E-UTRA, GSM, UMTS and LTE are described in documents from an organization called the “3rd Generation Partnership Project” ” (3GPP). The CDMAZ2000 is described in documents from an organization called “3rd Generation Partnership Project 2” (3GPP2). audio and patterns can represent cellular wireless technologies that are known in the art.
For the sake of brevity and clarity, terminology associated with the W-CDMA and LTE standards, promulgated in accordance with the 3GPP standards by the International Telecommunications Union (ITU) is used. It should be emphasized that the technologies described here are applicable to other technologies, such as the technologies and standards mentioned above.
Single Carrier Frequency Division Multiple Access (SC-FDMA), which uses single carrier modulation and frequency domain equalization, has similar performance and essentially the same overall complexity as OFDMA systems.
An SC-FDMA signal has a lower peak-to-average power ratio (PAPR) because of its inherent single-carrier structure.
SC-FDMA has attracted a great deal of attention, especially in uplink communications, where a lower PAPR considerably benefits the mobile terminal in terms of transmission power efficiency.
SC-FDMA is used in uplink multiple access in LTE 3GPP or evolved UTRA.
Referring to Figure 1, a multiple access wireless communication system according to an embodiment is illustrated.
An access point 100 (e.g., base station, evolved NOB (eNB) or the like) includes multiple antenna groups, one including 104 and 106, another including 108 and 110, and an additional group including 112 and 114. two antennas are shown for each antenna group, however more or less antennas can be used for each antenna group.
A mobile entity 116 is in communication with antennas 112 and 114, where antennas 112 and
114 transmit information to mobile entity 116 over a forward link 120 and receive information from mobile entity 116 over a reverse link 118. A mobile entity 122 is in communication with antennas 104 and 106, where antennas 104 and 106 transmit information to the mobile entity 122 over a forward link 126 and receive information from the mobile entity 122 over a reverse link 124. In a Frequency Division Dual (FDD) system, the communication links 118, 120, 124 and 126 may use different frequencies for communication. For example, forward link 120 may use a different frequency than that used by reverse link 118.
Each group of antennas and/or the area in which they are designed to communicate is often referred to as an access point sector. In certain embodiments, the antenna groups are each designed to communicate with mobile entities in a sector of the areas covered by access point 100.
In communication over the forward links 120 and 126, the transmit antennas of the access point 100 can use beamforming to improve the signal-to-noise ratio of the forward links to the different mobile entities 116 and 122. In addition, an access point that uses beamforming to transmit to randomly dispersed mobile entities across its coverage causes less interference from mobile entities in neighboring cells than an access point transmitting through a single antenna to all of its mobile entities.
An access point can be a fixed station used to communicate with the terminals and can also be referred to as an access point, a NODE, an eNodeB or some other terminology. A mobile entity may also be referred to as an access terminal (AT), a user equipment (UE), a mobile station, a wireless communication device, terminal or the like. Figure 2 is a block diagram of one embodiment of a transmitter system 210 (also known as an access point) and a receiver system 250 (also known as a mobile entity) in a MIMO system 200. The transmitter system 210 and the receiver system 250 may include other components that are not shown in Figure
2. For example, transmitter system 210 may include a wired and/or wireless interface for a return transport channel connection, while receiver system 250 may be devoid of any return transport carnal interface and may be configured for portability, for example, by the inclusion of a portable battery system, a battery charging system and energy conservation components. In contrast, transmitter system 210 may be devoid of a portable battery system or related components and may be configured to connect to an external power source. Under such an interpretation, system 200 can be understood as illustrating a cellular communications configuration that includes a base station 210 and a mobile entity 250. It should also be appreciated that System 200 can also be interpreted as peer mobile entities depicted in a configuration. P2P, with transmitter system 210 being a first even mobile entity and receiving system 250 being a second even mobile entity. Figure 2 can therefore be interpreted as depicting a cellular or P2P configuration and is not incompatible with a P2P-cellular dual configuration. In transmitter system 210, traffic data for a number of data streams is provided from a data source 212 to a transmission data processor (TX)
214. In one embodiment, each data stream is transmitted through a respective transmit antenna. Data processor TX 214 formats, encodes and interleaves the traffic data stream for each data stream based on the particular encoding scheme selected for that data stream to provide encoded data.
The encoded data for each data stream can be multiplexed with pilot data using OFDM techniques. Pilot data typically constitutes a known data pattern that is processed in a known manner and can be used in the receiving system to estimate the channel response. The multiplexed coded and pilot data for each data stream is then modified (eg, mapped symbols) based on a particular modulation scheme (eg, Binary Phase Shift Switching (BPSK), Phase Shift Switching by Quadrature (QOPSK), M-ary Phase Shift Keying (M-PSK) or Multi-Level Quadrature Amplitude Modulation (M-OAM)) selected for this data stream to provide modulation symbols. The data rate, encoding, and modulation for each data stream can be determined by instructions carried out by a processor 230, which can be in operative communication with a memory 232.
The modulation symbols for the data streams can then be provided to a MIMO TX 220 processor, which can also process the modulation symbols (e.g. for OFDM). The MIMO processor TX 220 then provides Nf modulation symbol streams at Nf transmitters (TMTRs) 222a to 222t. In certain modes, the processor
MIMO TX 220 applies beamforming weights to the symbols in the data streams and to the antenna from which the symbol is being transmitted. Each transmitter 222 receives and processes a respective stream of symbols to provide one or more analog signals and also conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. No-modulated signals from transmitters 222a to 222t are transmitted from N antennas 224a to 1324t, respectively. In receiver system 250, the transmitted modulated signals are received by Nx antennas 252a to 252r, & The signal received from each antenna 252 is provided to a respective receiver (RCVR) 254a to 254r. Each receiver 254 conditions (eg, filters, amplifies, and downconverts) a respective received signal, digitizes the conditioned signal to provide samples, and also processes the samples to provide a corresponding "received" symbol stream. An RX data processor 260 then receives and processes the Nx symbol streams received from the Ns receivers 254 based on a particular receiver processing technique to provide Nf "detected" symbol streams. The RX data processor 260 then demodulates, deinterleaves and decodes each detected symbol stream to retrieve the traffic data for the data stream. The processing by the RX 260 data processor is complementary to that performed by the MIMO TX 220 processor and by the TX 2i4 data processor in the transmitting system
210. A processor 270 periodically determines which precoding matrix to use. Processor 270 formulates a reverse link message comprising a matrix index portion and a rank value portion and may be in operative communication with a memory 272. Processor 270 may be operatively coupled to memory 272. Memory 272 may retain instructions and/or program data which, when executed by processor 270, cause receiver 250 to perform one or more of the P2P authorization technologies described in more detail later in the report for performance by a mobile entity.
The reverse link message may comprise different types of information relating to the communication link and/or the received data stream. The reverse link message is then processed by a TX data processor 238, which also receives traffic data for a number of data streams from a data source 236, modulated by a modulator 280, conditioned by transmitters 254a to 254r, and transmitted back to the transmitter system 210.
At transmitter system 210, modulated signals from receiver system 250 are received by antennas 224, conditioned by receivers 222, demodulated by demodulator 240, and processed by RX data processor 242 to extract the reverse link message transmitted by receiver system 250. Processor 230 then determines which precoding matrix to use to determine the beamforming weights, then processes the extracted message. Processor 230 may be operatively coupled to memory 232. Memory 232 may hold instructions and/or program data which, when executed by processor 230, cause transmitter 210 to perform the operations of a network entity, e.g., a base station, as described in more detail later in the report. Alternatively, if system 200 is interpreted as portraying a P2P configuration between peer mobile entities, memory 232 may hold instructions and/or program data which, when executed by processor 230, cause transmitter 210 to perform one or more of P2P authorization to be performed by a mobile entity, as described in more detail later in the report.
Figure 3 shows a wireless communication system 300, configured to support a number of users, in which the present teachings can be implemented. System 300 provides communication for multiple cells 302, such as, for example, macro cells 3022-3029, with each cell being serviced by a corresponding access node 304 (e.g., access nodes 304a-3049). As shown in Figure 3, mobile entities 306 (for example, mobile entities 3062-3061) can be dispersed at various locations throughout the system over time. Each mobile entity 306 may communicate with one or more access nodes 304 on a forward link ("EL") and/or a reverse link ("RL") at a given time, depending on whether the mobile entity 306 is and if it is in soft handoff (if applicable), for example. Wireless communication system 300 can provide service over a large geographic region. For example, the 302a-302g macrocells can cover a few blocks in an urban or suburban neighborhood or a few square miles in a rural setting. Each of the access nodes 304a-304g may include a return transport channel interface for connecting to a core network (not shown). The core network may include a number of network entities to control the operation of system 300 and interoperations with other networks, for example, the core network may include an MME, which may be configured as a computer server which includes configured processing modules for mobility management functions.
In one respect, these functions can include P2P authorization methodologies, as revealed in more detail later in the report.
In accordance with the subject aspects of this description, a wireless network (eg a 3GPP network) is provided which has a feature to utilize a spectrum provider (eg an LTE network provider) for point-to-point communication. point (P2P) and, more particularly, to manage the spectrum in order to enable or improve the concurrent use of P2P and cellular within a common area.
In this context, P2P communication is a direct communication between two or more mobile entities without the need to transport the data communicated through an access node or core network node.
As noted above, in a cellular system, P2P communication can supplement, but not entirely replace, the cellular mode of communication most commonly used between mobile entities and base stations for voice and data communication.
Figure 4 shows an embodiment of a communication system 400 comprising mobile entities 406, 408, 410 in communication via eNBs 402, 404 of a radio access network (RAN) and via direct wireless connections.
The pictured example illustrates even discovery for (1) UEs 408, 410 camped in a cell in the same eNB 404 and (2) UEsS 406, 410 camped in cells for respective different eNBs 402, 404.
Peer discovery is a procedure by which UEsS detect the availability of other services advertised on UEs within a radio frequency (RF) proximity and may generally involve peer announcements by mobile entities and peer detection by mobile entities of services advertised by peer mobile entities.
Peer mobile entities can perform detection, whereby authorized mobile entities can receive information in order to be able to perform detection (eg security keys or the like). Furthermore, peer mobile entities can perform announcement, in which authorized mobile entities can receive information in order to be able to announce a discovery identifier (for example, security keys). Each mobile entity refrains from announcing a discovery identifier for which it has not been authorized. In addition, peer mobile entities can perform direct communication, in which each mobile entity refrains from establishing direct communication with an advertisement for a discovery identifier for which it was not authorized. The core network may control authorization for P2P operations, including, for example, peer detection, peer announcement and P2P communication, using one or more mobile entities, for example, an MME, A network or spectrum provider may authorize a mobile entity to use the network spectrum to carry out the P2P communication procedures described above. The mobile entity may not be provisioned with P2P parameters and may be expected to request authorization for each procedure or set of procedures. For example, the mobile entity can request authorization for detection, detection and advertisement and/or direct communication. Authorization based on the techniques described here can be: (a) by tracking area for tracking area update (TAU) procedures; (b) while attached for attached procedures; and/or (c) based on the lifetime of carriers reserved for Evolved Packet System (EPS) session management (ESM) procedures.
In accordance with one or more aspects of the modalities described herein, techniques are provided for P2Z2P authorization using stratum no-access (NAS) procedures. As known in the art, an access layer refers to a functional layer in a telecommunications stack (eg UMTS or LTE) between the radio network and the UE used for radio access and communication. A non-access stratum similarly refers to a functional layer in a telecommunications stack (eg UMTS or LTE) between the core network and the UE used for control functions, eg mobility management, call control , session management Or identity management. Accordingly, a NAS procedure refers to a procedure that uses the NAS.
For P2P authorization using NAS procedures, two general types of technique can be used. The first type of technique can include ESM procedures, including P2P authorization based on new ESM procedures and P2P authorization based on existing ESM procedures. The second type of technique can include P2P authorization based on P2P EPS Mobility Management (EMM) procedures. In related aspects, P2P subscription data for a given mobile entity can be delivered to a management entity, such as, for example, an MME, by a native subscriber server (HSS) or the like using a procedure of the type insertion of subscriber data.
Regarding first P2P authorization based on new ESM procedures, this procedure can be used to request authorization to announce each discovery identifier or to establish each direct peer communication from a management entity (eg MME). This P2P authorization procedure can also be applied to a single general authorization for P2P service.
Referring to Figure 5, in one embodiment, a system 500 may comprise at least one mobile entity (e.g., a UE 502), at least one network entity (e.g., an eNB 504), and at least one management entity. (eg an MME 506,) from a core network. As shown, the UE 502 can optionally send a P2P authorization request message 510 to the MME 506 via the NAS at time t'. The P2P authorization message can be, or can include, one or more identifiers or other data signals that are recognizable by the network entity as a request to perform one or more P2P operations. At t, if the UE 502 requests authorization for a specific discovery identifier, the MME 506 can verify that the discovery identifier is contained in a signature of the UE 502 and/or verify that the discovery identifier is not expired. If the discovery identifier is not present or expired, the MME 506 may send a corresponding NAS reject message to the UE 502 with a corresponding cause value (e.g., not authorized for this discovery identifier). If all checks are successful, the MME 506 can send a message to accept P2P authorization 512 to the UE 502 (via the NAS) and/or the eNB 504 (via the access layer). The message to accept P2P authorization can be, or can include, one or more identifiers or other data signals that are recognizable by the mobile entity as an authorization to carry out one or more operations.
P2P. At t;3, the eNB 504 may send a P2P Radio Resource Control (RRC) Configuration Request 514 to UE 502. The P2P RRC Configuration Request 514 may be piggybacked the message to accept authorization 512. In ts, the UE 502 may send a complete RRC configuration message 516 to the eNB 504. At ts, the UE 502 may optionally send a complete P2P authorization message 518 to the MME 506 via the NAS. The new ESM procedure described above can be initiated by the network and accepted by the UE 502. The UE 502 can trigger the ESM procedure by sending a specific ESM message with a certain procedure transaction ID (PTI) or the like. The behavior of the UE 502 and the network for timer expirations, retransmissions and/or other abnormal scenarios can be handled in a way that is similar to existing ESM procedures.
In related aspects, the UE 502 may initiate a P2P modification request, such as, for example, to add/replace advertisement or connection establishment of new/existing discovery identifiers, or to modify parameters such as quality of service (QoS) . In other related aspects, the MME 506 may initiate a request to disable P2P, which may be initiated, for example, by changing the signature data in the HSS or the like.
With respect to P2P authorization based on existing ESM procedures, this procedure may use a Packet Data Network (PDN) connectivity request and EPS bearer context messages (for example, by activating a context request from default EPS carrier, by modifying an EPS carrier context request, etc.). This P2P authorization procedure can be used to request authorization to announce each discovery identifier or to establish each direct peer communication from an MME or similar, and can also apply to a single general authorization for P2P service.
It is observed that P2P authorization based on existing ESM procedures may result in core network resources being reserved for P2P service due to activation of the corresponding carriers.
In related aspects, a P2P authorization for discovery is provided which involves the use of existing ESM procedures.
Referring to Figure 6, in one embodiment, system 600 may comprise at least one mobile entity (e.g., a UE 602), at least one network entity (e.g., an eNB 604), and at least one management entity. (eg MME 606). The call flow shown in Figure 6 is substantially similar to the call flow shown in Figure 5 for The new ESM procedure.
As shown in Figure 6, UE 602 can optionally send a connectivity request message from PDN 610 to MME 606 via the NAS at time t1.
At t, if the P2P authorization checks are successful, the MME 606 can send a default active EPS 612 carrier context message to the UE 602 (via the NAS) and/or the eNB 604 (via the access layer) . At t;, the eNB 604 may send a P2P Radio Resource Control (RRC) configuration request 614 to the UE 602. The P2P configuration request of RRC 614 may be carried in the active default EPS carrier context message 612. In ta.
The UE 602 may send a complete RRC configuration message 616 to the eNB 604. In ts, the UE 602 may optionally send a message to accept default active EPS carrier context 618 to the MME 606 via the NAS.
PDN connectivity request reuse can be advantageous in situations where the UE 602 is trying to request connectivity to a particular PDN Gateway (P-GW) for P2P services.
Unnecessary overhead can result if specific parameters, such as, for example, EPS Carrier ID, Access Point Name (APN), P-GW address, or EPS QoS, are not requested.
In other related aspects, a P2P authorization for direct communication involving the use of existing ESM procedures is provided.
Referring to Figure 7, in one embodiment, system 700 may comprise at least one mobile entity! (e.g., a UE 702), at least one network entity (e.g., an eNB 704), and at least one management entity (e.g., the MME 706). The call flow shown in Figure 7 is substantially similar to the call flows shown in Figures 5 and 6. As shown in Figure 7, the UE 702 may optionally send a bearer resource allocation request message 710 to the MME 76 via the NAS at time t,. At t, if the P2P authorization checks are successful, the MME 706 can send an active dedicated EPS carrier context message 712 to the UE 702 (via the NAS) and/or the eNB 704 (via the access layer) . At t;, the eNB 704 may send a P2P Radio Resource Control (RRC) configuration request 714 to the UE 702. The RRC 714 P2P configuration request may be carried in the active dedicated EPS carrier context message 712. At ts, UE 702 may send a complete RRC configuration message 716 to eNB 704. At ts, UE 702 may optionally send a message to accept active dedicated EPS carrier context 718 to MME 706 through the NAS.
P2P authorization for direct communication can be linked to the activation of a dedicated carrier with its corresponding QoS, which can be useful for session mobility between a link and direct P2P communication through an Extended Area Network (WAN). Alternatively, or in addition, the announcement of additional discovery identifiers may be linked to the use of dedicated carriers.
With respect now to P2P authorization based on existing EMM procedures, P2P authorization can be carried in attachment and/or in TAU procedures, which may involve the addition of new information elements (TES) with P2P specific information.
The implementation of EMM procedures can mainly be used for a single general authorization for P2P service.
Referring to Figure 8, a call flow for a general P2P authorization is provided based on an attached procedure. In one embodiment, a system 800 may comprise at least one mobile entity (e.g., a UE 802), at least one network entity (eg an eNB 804), a first management entity (eg a new MME 806), a second management entity (eg an old MME/SGSN (GPRS (radio) service support node) general packet service))) 808, a first core network entity (eg an Equipment Identity Register (EIR) 810) and a second core network entity (eg an HSS 812,) in operative communication a with the other. aspects involving identifier verification, authentication and authorization are a part of the normal attached procedure; thus, Figure 8 shows the aspects related to the registry.
In ti, the UE 802 can include a P2P authorization request (e.g., P2P authorization request or discovery IE) in a registration message (e.g., append request message 820), such as, by example, for the new MME 806 through “the NAS. Known UE identifier and authentication checks — can be performed up to t;. At t;, the new MME 806 can verify P2P signature data for the UE 802 and can provide a P2P authorization response (e.g., P2P authorization response IE) in a message to accept registration (e.g., the message to accept appends 830) to the UE 802.
In related respects, the same or similar IEs can be included in a TAU procedure. For example, the TAU procedure may involve including the P2P authorization request IE in a TAU request message from a UE to an MME, as well as including the P2P authorization response IE in a message to accept TAU from the MME to o EU. In other related aspects, P2P authorization can be for the list of tracking areas included in the message to accept attachments or in the message to accept TAU.
In view of the exemplary systems shown and described here, the methodologies that can be implemented according to the subject revealed will be better appreciated with reference to several flowcharts. Although, for the purpose of simplifying the explanation, the methodologies are shown and described as a series of acts/blocks, it should be understood and appreciated that the claimed subject matter is not limited by the number or order of blocks, as some blocks may occur in different orders and/or substantially at the same time with other blocks that is shown and described here. Furthermore, not all blocks illustrated may be required to implement the methodologies described here. It should be understood that functionality associated with blocks may be implemented by software, hardware, a combination of them, or any other suitable mechanism (eg device, system, process or component). In addition, it should be appreciated that the methodologies disclosed throughout this report may be stored in the form of encoded instructions in an article of manufacture, for example, a non-transient computer-readable medium, to facilitate the transport and transfer of such methodologies. for multiple devices. When encoded instructions are executed by a processor, the processor can cause a device that the processor controls to carry out the methodology. Those skilled in the art will understand and appreciate that a methodology can alternatively be represented as a series of interrelated states or events, such as in a state diagram.
In accordance with one or more subject matter aspects of this description, methods for P2P authorization based on ESM procedures are provided. Referring to Figure 9, a methodology 900 that may be performed in a wireless communication apparatus such as a mobile entity (e.g., a UE) is illustrated. The elements of the 900 methodology can be shown alternatively to the call flow diagram shown in Figure 5.
All operations listed in Figure 9 can be performed by the mobile entity or similar device to engage in F2P communications with another peer device. P2P authorization can be for P2P communications - distinct from cellular communications between the mobile entity and a base station - in a wireless communication system that also makes use of cellular communications between base stations and mobile entities. P2P authorization can operate under a control scheme in which it is necessary for each mobile entity to be required to obtain P2P authorization prior to the commencement of certain P2P operations, including P2P discovery and/or P2P communication.
In the absence of P2P authorization, such a control scheme may require the mobile entity to refrain from performing any P2P operations that might interfere with cellular operation, and the mobile entity may therefore be limited to operating in a cellular mode until the P2P authorization is completed.
Method 900 may involve, at 910, the mobile entity receiving a message to accept P2P authorization from a management entity (eg, an MME) via a NAS.
The message to accept P2P authorization may include one or more data or identifiers that are recognized by the mobile entity as authorizing one or more operations to allow or support a P2P operation.
Method 900 may involve, at 920, the mobile entity receiving a P2P RRC configuration request from a network entity (e.g., an eNB). The P2P configuration request may comprise a wireless data signal which the mobile entity recognizes as requesting the mobile entity to configure a P2P operation in a specified manner.
Method 900 may involve, at 930, the mobile entity sending a complete RRC P2P configuration message to the network entity via an access layer.
The P2P configuration complete message can include data that indicates that a specified P2P configuration is complete.
Figure 10 illustrates additional operations or aspects that may be performed in association with or as part of method 900. One or more of the additional operations shown in Figure 10 may optionally be performed by the mobile entity as part of method 900, describe an aspect modifying one of the method elements
900 or a more detailed algorithm to perform one of the elements of method 900. These elements can be performed in any operative order or can be encompassed by a development algorithm without needing a particular chronological performance order. Operations are performed independently and are not mutually exclusive. Therefore, any such operation can be performed regardless of whether another downstream or upstream operation is performed. For example, if method 900 includes at least one of the operations 940-972, then method 900 can terminate after at least one operation, without necessarily having to include any subsequent downstream operations that may be illustrated(s).
Referring to Figure 10, method 900 may also involve, at 940, sending by the mobile entity a P2P authorization request message to the managing entity via the NAS. This operation 940 can be performed prior to receiving the message to accept P2P authorization 910, as also shown at 510 in Figure 5. Method 900 may also involve, at 950, the transmission by the mobile entity of a complete P2P authorization message to the management entity through the NAS. This operation 959 can be performed by the mobile entity after sending a complete RRP P2P configuration message to the network entity, as shown in block 930 of Figure 9.
In related aspects, and again referring to Figure 10, method 900 for P2P authorization may comprise an authorization to discover on one or more peer devices within a common area of a cellular wireless communication system. For example,
receiving the message to accept P2P authorization 910 may involve, at 960, the receipt by the mobile entity of an active default EPS carrier context message. Method 900 may also involve, at 962, transmitting a message to accept active default EPS carrier context to the management entity through the NAS, in response to the active default EPS carrier context message.
In other related aspects, P2P authorization can comprise an authorization for direct communication. Receiving the message to accept P2P authorization 910 may involve, at 970, receiving an active dedicated EPS carrier context message. Method 900 may also involve, at 972, transmitting a message to accept active dedicated EPS carrier context to the managing entity through the NAS.

Elements of the 900 methodology can be illustrated in an alternative to the call flow diagram shown in Figure 5.
All operations listed can be performed by MME or similar apparatus to authorize P2P communications in a cellular communications network. As noted above, FP2P communications between mobile entities are distinct from cellular communications between each mobile entity and a base station. P2P authorization can operate under a control scheme in which each mobile entity is required to obtain P2P authorization prior to the initiation of certain P2P operations, including 'P2P discovery and/or P2P communication. In the absence of P2P authorization, such a control scheme may require the mobile entity to refrain from performing any P2P operations that might interfere with cellular operation, and the mobile entity may therefore be restricted to operating in a cellular mode until P2P authorization is completed.
Method 1100 may involve, at 1110, receiving a P2P authorization request message from a mobile entity via a NAS. Method 1100 may involve, at 1120, performing at least one P2P authorization check of the mobile entity based at least in part on the received P2P authorization request message. Method 1100 may involve, at 1130, sending a message to accept P2P authorization to a mobile entity via the NAS, in response to at least one verification being successful.

One or more of the additional operations shown in Figure 12 may optionally be performed by the management entity as part of method 1100, describe a aspect that modifies one of the elements of method 1100 or a more detailed algorithm to perform one of the elements of method 1100. These elements can be performed in any operative order or can be encompassed by a development algorithm without requiring a particular chronological performance order. Transactions are performed independently and are not mutually exclusive. Therefore, any such operation can be performed regardless of whether Another downflow or upstream operation is performed. For example, if method 1100 includes at least one of the operations 1140-1164, then method 1100 can terminate after at least One Operation, without necessarily having to include any subsequent downstream operations that may be illustrated(s).
Referring to Figure 12, performing at least one verification 1120 may involve, at 1140, determining whether the specific ID or specific prefix associated with the mobile entity associates a signature of the mobile-entity. Alternatively, or in addition, performing the at least one check may involve, at 1142, determining whether the specific TD or specific prefix associated with the mobile entity is unexpired.
In related aspects, P2P authorization can comprise an authorization for discovery. In such cases, receiving P2P authorization request message 1110 may involve, at 1150, receiving a PDN connectivity request message. Sending the message to accept P2P authorization 1130 may involve, at 1152, sending an active default EPS carrier context message to the mobile entity. Method 1100 may also involve, at 1154, receiving a message to accept default active EPS carrier context from the mobile entity through the NAS, in response to the default active EPS carrier context message.
In other related aspects, P2P authorization can comprise an authorization for direct communication. In such cases, receiving the P2P authorization request message may involve, at 1160, receiving a carrier resource allocation request message from the mobile entity. Sending the message to accept P2P authorization may involve, at 1162, sending an active dedicated EPS bearer context message to the mobile entity. Method 1100 may also involve, at 1164, receiving a message to accept active dedicated EPS carrier context from the mobile entity through the NAS, in response to the active dedicated EPS carrier context message.
