Technical Field

[0001] Cross - reference to related applications

[0001] This application claims the benefit and priority of PCT Application No. PCT / CN2019 / 090297, filed on June 6, 2019, which has been assigned to the assignee of this application and is hereby incorporated by reference in its entirety as if fully set forth herein and for all applicable purposes.

[0002]

[0002] Aspects of the present disclosure relate to wireless communication, and more particularly, to techniques for service priority information for multi - SIM user equipment (UE) paging.

Background Art

[0003]

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephone, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple - access technologies that can support communication with multiple users by sharing available system resources (such as bandwidth, transmit power, etc.). Examples of such multiple - access systems include, for example, the 3rd Generation Partnership Project (3GPP (registered trademark)) Long Term Evolution (LTE (registered trademark)) system, LTE - Advanced (LTE - A) system, Code Division Multiple Access (CDMA) system, Time Division Multiple Access (TDMA) system, Frequency Division Multiple Access (FDMA) system, Orthogonal Frequency Division Multiple Access (OFDMA) system, Single - Carrier Frequency Division Multiple Access (SC - FDMA) system, and Time Division - Synchronous Code Division Multiple Access (TD - SCDMA) system.

[0004]

[0004] These multiple access technologies are employed in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at urban, national, regional, and even global levels. New radio (e.g., 5G NR) is an example of a new telecommunications standard. NR is a set of extensions to the LTE mobile standard published by 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving service, utilizing new spectrum, and better integrating with other open standards by using OFDMA with cyclic prefixes (CP) on downlink (DL) and uplink (UL). For these purposes, NR supports beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation.

[0005]

[0005] However, as the demand for mobile broadband access continues to increase, further improvements to NR and LTE technologies are needed. Preferably, these improvements should be applicable to other multiple access technologies and to the telecommunications standards that employ these technologies. [Overview of the project]

[0026]

[0040] For ease of understanding, the same reference numerals are used to designate the same elements common to each figure, where possible. It is intended that elements disclosed in one embodiment may be usefully utilized for other embodiments without specific demonstration.

[0027]

[0041] Aspects of this disclosure provide apparatus, methods, processing systems, and computer-readable media for multi-SIM user equipment (UE) paging. A multi-USIM UE may communicate with a first network using a first SIM and with a second network using a second SIM (or a second set of proofs for the second network stored in the first SIM). In some cases, communication with the first network and communication with the second network share the same TX / RX chain. In such cases, when the UE receives a paging message related to the second network while communicating with the first network, the UE may tune into the second network to receive information, potentially disrupting critical services on the first network.

[0028]

[0042] Accordingly, aspects of this disclosure provide techniques that enable a UE to determine whether to respond to a paging message in a second network. For example, in some cases, the paging message may contain service priority information indicating the priority of information to be received corresponding to the paging message. The UE may use the service priority information to determine whether to respond to the paging message or ignore it.

[0029]

[0043] The following descriptions are illustrative and not intended to limit the scope, applicability, or examples described in the claims. Modifications may be made to the function and configuration of the elements described without departing from the scope of this disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the methods described may be performed in a different order than described, and various steps may be added, omitted, or combined. Also, features described in some examples may be combined in some other examples. For example, an apparatus may be implemented or a method may be carried out using any number of embodiments described herein. Furthermore, the scope of this disclosure shall cover any such apparatus or method carried out using other structures, functions, or structures and functions in addition to or in addition to the various embodiments of this disclosure described herein. It should be understood that any embodiment of this disclosure disclosed herein may be carried out by one or more elements of the claims. The word “exemplary” is used herein to mean “acting as an example, case, or illustration.” Any embodiment described herein as "exemplary" should not necessarily be construed as being more preferable or advantageous than any other embodiment.

[0030]

[0044] The techniques described herein can be used for a variety of wireless communication technologies, including 3GPP Long-Term Evolution (LTE), LTE-A, Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms “network” and “system” are often used interchangeably.

[0031]

[0045] CDMA networks can implement radio technologies such as Universal Terrestrial Radio Access (UTRA) and cdma2000. UTRA includes wideband CDMA (WCDMA®) and other variations of CDMA. cdma2000 covers the IS-2000, IS-95, and IS-856 standards. TDMA networks can implement radio technologies such as Global System for Mobile Communications (GSM®). OFDMA networks can implement radio technologies such as NR (e.g., 5G RA), Advanced UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi®), IEEE 802.16 (WiMAX®), IEEE 802.20, and Flash-OFDMA. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the "Third Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization called the "Third Generation Partnership Project II" (3GPP2).

[0032]

[0046] New Radio (NR) is a new wireless communication technology under development in collaboration with the 5G Technology Forum (5GTF). NR access (e.g., 5G NR) can support a variety of wireless communication services, including extended mobile broadband (eMBB) targeting broadband frequencies (e.g., 80 MHz or above), millimeter wave (mmW) targeting high carrier frequencies (e.g., 25 GHz or above), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC techniques, and / or mission-critical services targeting ultra-high reliability low-latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmit time intervals (TTIs) to meet their respective quality of service (QoS) requirements. Furthermore, these services may coexist within the same subframe.

[0033]

[0047] The techniques described herein may be used for the wireless networks and radio technologies described above, as well as for other wireless networks and radio technologies. For clarity, embodiments may be described herein using terms generally related to 3G and / or 4G wireless technologies, but embodiments of this disclosure may be applied to other generation-based communication systems, such as 5G and beyond, including NR technologies.

[0034]

[0048] Figure 1 shows an exemplary wireless communication network 100 in which embodiments of the present disclosure may be performed. For example, the wireless communication network 100 may be an NR system (e.g., a 5G NR network). As shown in Figure 1, the wireless communication network 100 may communicate with a core network 130. The core network 130 may communicate with one or more BS110s and / or UE120s via one or more interfaces, and also with an application server 140, as described in more detail below with respect to Figure 2. As shown in Figure 1, the UE120a includes a paging module 114 which may be configured to perform the operations shown in one or more of Figures 4 to 11, as well as other operations described herein for service priority information for multi-SIM UE paging. Furthermore, as shown in Figure 1, for example, the BS110a also includes a paging module 112 which may be configured to perform the operations shown in one or more of Figures 4 to 11, as well as other operations described herein for service priority information for multi-SIM UE paging.

[0035]

[0049] As shown in Figure 1, the wireless communication network 100 may include several base stations (BS) 110 and other network entities. A BS may be a station that communicates with user equipment (UE). Each BS 110 may provide communication coverage to a specific geographic area. In 3GPP, the term “cell” may refer to the coverage area of ​​a node B (NB) and / or the NB subsystem that services this coverage area, depending on the context in which the term is used. In NR systems, the terms “cell” and BS, next-generation node B (gNB or gnode B), access point (AP), distributed unit (DU), carrier, or transmit / receive point (TRP) may be used interchangeably. In some examples, a cell may not necessarily be fixed, and the geographic area of ​​a cell may move according to the location of a mobile BS. In some examples, BS may be interconnected with each other and / or with one or more other BS or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces, such as direct physical connections, wireless connections, and virtual networks, using any suitable transport network.

[0036]

[0050] Generally, any number of wireless networks can be deployed within a given geographical area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RATs are sometimes called radio technologies or air interfaces. Frequencies are sometimes called carriers, subcarriers, frequency channels, tones, or subbands. Each frequency may support a single RAT within a given geographical area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0037]

[0051] A BS can provide communication coverage to macrocells, picocells, femtocells, and / or other types of cells. A macrocell can cover a relatively large geographical area (e.g., a radius of several kilometers) and can enable unrestricted access by UEs (Users) subscribed to the service. A picocell can cover a relatively small geographical area and can enable unrestricted access by UEs subscribed to the service. A femtocell can cover a relatively small geographical area (e.g., a home) and can enable limited access by UEs associated with a femtocell (e.g., UEs in a limited subscriber group (CSG), UEs for users in a home, etc.). A BS for a macrocell is sometimes called a macroBS. A BS for a picocell is sometimes called a picoBS. A BS for a femtocell is sometimes called a femtoBS or homeBS. In the example shown in Figure 1, BS110a, 110b, and 110c could be macroBSs for macrocells 102a, 102b, and 102c, respectively. BS110x may be a pico BS for picocell 102x. BS110y and 110z may be femto BS for femtocells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.

[0038]

[0052] The wireless communication network 100 may also include relay stations. A relay station is a station that receives transmissions of data and / or other information from an upstream station (e.g., a BS or UE) and sends transmissions of that data and / or other information to a downstream station (e.g., a UE or BS). A relay station may also be a UE that relays transmissions to other UEs. In the example shown in Figure 1, relay station 110r may communicate with BS110a and UE120r to enable communication between BS110a and UE120r. Relay stations are sometimes called relay BS, relays, etc.

[0039]

[0053] The wireless communication network 100 may be a heterogeneous network including different types of BS, such as macro BS, pico BS, femto BS, and relays. These different types of BS may have different transmission power levels, different coverage areas, and different effects on interference in the wireless communication network 100. For example, a macro BS may have a high transmission power level (e.g., 20 watts), while pico BS, femto BS, and relays may have a lower transmission power level (e.g., 1 watt).

[0040]

[0054] The wireless communication network 100 may support synchronous or asynchronous operation. In synchronous operation, BSs may have similar frame timings, and transmissions from different BSs may be approximately time-coordinated. In asynchronous operation, BSs may have different frame timings, and transmissions from different BSs may not be time-coordinated. The techniques described herein may be used for both synchronous and asynchronous operation.

[0041]

[0055] The network controller 130 can be coupled to a set of BS110s and coordinate and control these BS110s. The network controller 130 can communicate with the BS110s via backhaul. The BS110s can also communicate with each other (for example, directly or indirectly) via wireless backhaul or wireline backhaul.

[0042]

[0056] The wireless communication network 100 may be part of a radio access network (RAN) that communicates with a core network (CN) 140. The CN 140 may then communicate with an application provider, for example, via an application server (AS) 150. The embodiments of the CN 140 are described in more detail below with reference to Figure 2.

[0043]

[0057] UE120 (e.g., 120x, 120y, etc.) may be distributed across the entire wireless communication network 100, and each UE may be stationary or mobile. UEs may also be referred to as mobile stations, terminals, access terminals, subscriber units, stations, customer premises equipment (CPE), cellular phones, smartphones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet computers, cameras, game devices, netbooks, smartbooks, ultrabooks, instruments, medical devices or equipment, biosensors / devices, smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets, etc.), wearable devices, entertainment devices (e.g., music devices, video devices, satellite radios, etc.), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, or any other suitable devices configured to communicate via wireless or wired media. Some UEs can be considered machine-type communication (MTC) devices or advanced MTC (eMTC) devices. MTC UEs and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and location tags that can communicate with BS, other devices (e.g., remote devices), or any other entities. Wireless nodes can provide connectivity to or for a network (e.g., a wide area network such as the Internet or a cellular network) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0044]

[0058] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single-carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into several (K) orthogonal subcarriers, commonly also called tones or bins. Each subcarrier can be modulated with data. Generally, the modulation symbols are transmitted in the frequency domain in OFDM and in the time domain in SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the subcarrier spacing can be 15 kHz, and the minimum resource allocation (called a "resource block" (RB)) can be 12 subcarriers (or 180 kHz). Thus, the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048 for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), respectively. The system bandwidth can also be divided into subbands. For example, a subband may cover 1.08 MHz (e.g., 6 RBs), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively. In LTE, the basic transmit time interval (TTI) or packet duration is a 1 ms subframe. In NR, the subframe is still 1 ms, but the basic TTI is called a slot. A subframe contains a variable number of slots (e.g., 1, 2, 4, 8, 16, ... slots) depending on the subcarrier interval. An NR RB is 12 consecutive frequency subcarriers. NR may support a base subcarrier interval of 15 kHz, and other subcarrier intervals may be defined relative to the base subcarrier interval, e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. Symbol length and slot length scale with the subcarrier interval. CP length also depends on the subcarrier interval.

[0045]

[0059] NR may include support for half-duplex operation using TDD with OFDM with CP on uplink and downlink. Beamforming may be supported, and beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. In some examples, MIMO configurations in DL may support up to eight transmitting antennas with multilayer DL transmission of up to eight streams and up to two streams per UE. In some examples, multilayer transmission with up to two streams per UE may be supported. Aggregation of multiple cells may be supported with up to eight serving cells.

[0046]

[0060] In some examples, access to an air interface can be scheduled. A scheduling entity (e.g., a BS) allocates resources for communication between some or all devices and equipment within its service area or cell. A scheduling entity may be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more dependent entities. That is, for scheduled communication, dependent entities utilize the resources allocated by the scheduling entity. A base station is not the only entity that can function as a scheduling entity. In some examples, a UE can function as a scheduling entity, scheduling resources for one or more dependent entities (e.g., one or more other UEs), and other UEs can utilize the resources scheduled by the UE for wireless communication. In some examples, a UE can function as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In the mesh network example, UEs can communicate directly with each other in addition to communicating with scheduling entities.

[0047]

[0061] In some examples, two or more dependent entities (e.g., UEs) may communicate with each other using side-link signals. Real-world applications of such side-link communication may include public safety, proximity services, UE network relay, vehicle-to-vehicle (V2V) communication, Internet of Things (IoE) communication, IoT communication, mission-critical mesh, and / or various other suitable applications. Generally, side-link signals can refer to signals communicated from one dependent entity (e.g., UE1) to another dependent entity (e.g., UE2) without relaying the communication through the scheduling entity, although the scheduling entity (e.g., UE or BS) may utilize it for scheduling and / or control purposes. In some examples, side-link signals may be communicated using licensed spectrum (unlike wireless local area networks, which generally use unlicensed spectrum).

[0048]

[0062] In Figure 1, solid lines with double arrows indicate desired transmissions between a UE and a serving BS, which is a BS designated to service that UE, on the downlink and / or uplink. Fine dashed lines with double arrows indicate potentially interfering transmissions between the UE and the BS.

[0049]

[0063] Figure 2 is a block diagram showing exemplary architectures of a CN200 (e.g., CN140 in Figure 1) communicating with a RAN224 and an AS202 (e.g., AS150 in Figure 1) according to some aspects of the present disclosure. As shown in Figure 2, the exemplary architecture includes a CN200, a RAN224, a UE222, and a data network (DN)228 (e.g., operator services, internet access, or third-party services).

[0050]

[0064] The CN200 can host core network functions. The CN200 can be centrally deployed. CN200 functions can be offloaded (for example, to Advanced Wireless Services (AWS)) to handle peak capacity. As shown in Figure 2, the exemplary CN200 may be implemented by one or more network entities that perform network functions (NFs), including a network slice selection function (NSSF) 204, a network exposure function (NEF) 206, an NF repository function (NRF) 208, a policy control function (PCF) 210, an integrated data management function (UDM) 212, an application function (AF) 214, an authentication server function (AUSF) 216, an access and mobility management function (AMF) 218, a session management function (SMF) 220, a user plane function (UPF) 226, and various other functions (not shown), such as an unstructured data storage function (UDSF), an integrated data repository (UDR), a 5G-equipment identity register (5G-EIR), and / or a security edge protection proxy (SEPP).

[0051]

[0065] The AMF218 supports the following functions (some or all of the AMF functions may be supported in one or more instances of AMF): termination of the RAN control plane (CP) interface (N2), termination of the non-access layer (NAS) (e.g., N1), NAS cypherization and integrity protection, registration management, connection management, reachability management, mobility management, lawful interception (for AMF events and interfaces to L1 systems), transport for session management (SM) messages between UE222 and SMF220, transparent proxy for routing SM messages, access authentication, access permission, transport for short message service (SMS) messages between UE222 and SMS function (SMSF), and security anchor function (SEAF). Functionality) may include security context management (SCM) which receives keys from SEAF which it uses to derive access network-specific keys, location service management for regulatory services, transport for location service messages between UE222 and Location Management Function (LMF), and also between RAN224 and LMF, EPS bearer ID allocation for interacting with Advanced Packet Services (EPS), and / or UE mobility event notification, as well as / or other functions.

[0052]

[0066] The SMF220 may support session management (e.g., session establishment, modification, and release), UE IP address allocation and management, Dynamic Host Configuration Protocol (DHCP) functionality, termination of NAS signaling related to session management, downlink data notification, and traffic steering configuration for UPF for proper traffic routing. The UPF226 may support packet routing and forwarding, packet inspection, quality of service (QoS) processing, external protocol data unit (PDU) session points for interconnection to DN228, and anchor points for intra-RAT and inter-RAT mobility. The PCF210 may support an integrated policy framework that controls protocol functionality and / or provides policy rules for accessing subscription information for policy decisions in the UDR. The AUSF216 may act as an authentication server. The UDM212 may support authentication and key matching (AKA) certificate generation, user identity processing, access permissions, and subscription management. The NRF208 may support service discovery functionality and maintain NF profiles and available NF instances. The NSSF may support selecting a network slice instance to service the UE222, determining acceptable network slice selection assistance information (NSSAI), and / or determining the AMF set to be used to service the UE222. Furthermore, in some cases, the SMF220, UPF226, PCF210, AMF218, and RAN224 may be configured to perform operations for service priority information for multi-SIM UE paging according to some embodiments described herein.

[0053]

[0067] NEF206 can support capability and event exposure, secure delivery of information from external applications to the 3GPP network, and internal / external information conversion. AF214 can support application impact on traffic routing, access to NEF206, and / or interaction with policy frameworks for policy control.

[0054]

[0068] Figure 3 shows exemplary components of BS110 and UE120 (for example, in the wireless communication network 100 of Figure 1) that may be used to implement aspects of the present disclosure. For example, the antenna 352, processors 366, 358, 364, and / or controller / processor 380 of UE120, and / or the antenna 334, processors 320, 330, 338, and / or controller / processor 340 of BS110 may be used to perform various techniques and methods described herein. For example, as shown in Figure 3, the controller / processor 340 of BS110 includes a paging module 341 which may be configured to perform the operations shown in one or more of Figures 4 to 11, as well as other operations described herein for service priority information for multi-SIM UE paging. Furthermore, as shown in Figure 3, for example, the controller / processor 380 of the UE120 also includes a paging module 381 which can be configured to perform the operations shown in one or more of Figures 4 to 11, as well as other operations described herein for service priority information for multi-SIM UE paging.

[0055]

[0069] In BS110, the transmitting processor 320 may receive data from the data source 312 and control information from the controller / processor 340. The control information may be for the Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid ARQ Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Common PDCCH (GC PDCCH), etc. The data may be for the Physical Downlink Shared Channel (PDSCH), etc. The processor 320 may process the data and control information (e.g., encoding and symbol mapping) to obtain data symbols and control symbols, respectively. The transmitting processor 320 may also generate reference symbols, such as for the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Cell-Specific Reference Signal (CRS). The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may, where applicable, perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols, and provide the output symbol streams to modulators (MODs) 332a-332t. Each modulator 332 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The downlink signals from modulators 332a-332t may be transmitted via antennas 334a-334t, respectively.

[0056]

[0070] In UE120, antennas 352a-352r can receive downlink signals from BS110 and provide the received signals to demodulators (DEMOD) 354a-354r in the transceiver, respectively. Each demodulator 354 can adjust its respective received signal (e.g., filter, amplify, downconvert, and digitize) to acquire an input sample. Each demodulator can further process the input sample (e.g., for OFDM, etc.) to acquire a received symbol. MIMO detector 356 can acquire received symbols from all demodulators 354a-354r, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiving processor 358 can process the detected symbols (e.g., demodulate, deinterleave, and decode), provide the decoded data for UE120 to data sink 360, and provide the decoded control information to controller / processor 380.

[0057]

[0071] On the uplink, in UE120, the transmit processor 364 may receive and process data from data source 362 (for example, for a physical uplink shared channel (PUSCH)) and control information from controller / processor 380 (for example, for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for reference signals (for example, for a sounding reference signal (SRS)). Symbols from the transmit processor 364 may be precoded by the TX MIMO processor 366 where applicable, further processed by demodulators 354a-354r in the transceiver (for example, for SC-FDM, etc.), and transmitted to base station 110. In BS110, the uplink signal from UE120 is received by antenna 334, processed by modulator 332, detected by MIMO detector 336 where applicable, and further processed by receive processor 338 to obtain the decoded data and control information sent by UE120. The receiving processor 338 can provide the decoded data to the data sink 339 and the decoded control information to the controller / processor 340.

[0058]

[0072] Controllers / processors 340 and 380 can direct operations in BS110 and UE120, respectively. Controllers / processors 340 and / or other processors and modules in BS110 can execute or direct processes for the techniques described herein. Memories 342 and 382 can store data and program code for BS110 and UE120, respectively. Scheduler 344 can schedule UEs for data transmission on downlink and / or uplink.

[0059] Example service priority information for multi-SIM user device paging

[0073] A user device (UE), such as UE120, may include two or more subscriber identification modules (SIMs) and / or universal subscriber identification modules (USIMs). A UE with two or more SIMs is sometimes referred to as a multi-SIM device. In this disclosure, SIM may refer to either a SIM or a USIM. Each SIM may also include a unique international mobile subscriber identification information (IMSI) and service subscription information (e.g., UE service certificate). Each SIM may be configured to operate with a specific radio access technology (RAT), which allows the UE to communicate using different RATs that use each individual SIM.

[0060]

[0074] Many multi-SIM devices support multi-SIM multi-standby operation, using a single radio frequency (RF) chain to transmit and receive communications. Multi-SIM device implementations may use common radio and baseband components shared among multiple SIMs. For example, in some cases, a multi-SIM device may include a first SIM dedicated to operating in a first network (e.g., associated with a first RAT) and a second SIM dedicated to operating in a second network (e.g., associated with a second RAT), with both SIMs using a single RF chain to transmit and receive communications.

[0061]

[0075] In some cases, while communicating with the first network in a dedicated mode, the UE may detect a page in the second network, causing the UE to interrupt all operations on the first network and transition to the second network to respond to the page, regardless of the type (or priority) of information the page in the second network corresponds to. For example, in some cases, even if the page corresponds to low-priority information, the UE may still transition to the second network and interrupt all operations on the first network, which may involve interrupting critical services on the first network. In some cases, critical services may be defined by the UE's user and may include services used by the user, such as IMS voice services, game services, or other services.

[0062]

[0076] Therefore, in order to avoid the adverse effects of interrupting critical services in the first network (for example, related to the first SIM) due to a paging message detected in the second network (for example, related to the second SIM), aspects of the disclosure provide techniques that enable a UE to determine whether to respond to a paging message in the second network. For example, in some cases, service priority information that enables a UE to determine whether to establish a connection in the second network in response to the paging message may be included in the paging message transmitted in the second network.

[0063]

[0077] Figure 4 is a flowchart illustrating exemplary operation 400 for wireless communication according to several aspects of the present disclosure. Operation 400 may be performed by a first wireless node, such as a UE (e.g., UE120 in wireless communication network 100).

[0064]

[0078] Operation 400 may be implemented as a software component that runs on and operates on one or more processors (e.g., the controller / processor 380 in Figure 3). Furthermore, the transmission and reception of signals by the UE in operation 400 may be enabled, for example, by one or more antennas (e.g., the antenna 352 in Figure 3). In some embodiments, the transmission and / or reception of signals by the UE may be implemented via a bus interface of one or more processors (e.g., the controller / processor 380) that acquires and / or outputs signals.

[0065]

[0079] Operation 400 is initiated by communicating with a first network using a first set of certificates, where the UE includes a second set of certificates relating to a second network. In some cases, the first set of certificates is stored in a first general-purpose subscriber identification module (USIM). In other cases, the second set of certificates is stored in either the first USIM or the second USIM.

[0066]

[0080] In 404, the UE receives a paging message for information transmission in the second network, the paging message containing service priority information corresponding to the information transmission.

[0067]

[0081] In 406, the UE determines a service priority value corresponding to information transmission from the service priority information, based at least partially on the policy configuration information.

[0068]

[0082] In 408, the UE decides, at least partially, whether to respond to the paging message and establish a connection in the second network.

[0069]

[0083] In 410, the UE takes one or more actions based at least in part on the decision.

[0070]

[0084] Figure 5 is a flowchart illustrating exemplary operation 500 for wireless communication according to several aspects of the present disclosure. Operation 500 may be performed by a network entity, for example, an entity in a RAN. According to the aspect, operation 500 may be considered complementary to operation 400 performed by a UE.

[0071]

[0085] Operation 500 is initiated by communication with the user equipment (UE) in 502.

[0072]

[0086] In 504, the network entity determines that information needs to be sent to the UE.

[0073]

[0087] In 506, the network entity sends a paging message to the UE indicating that information needs to be sent to the UE, the paging message containing service priority information corresponding to the information that needs to be sent to the UE.

[0074]

[0088] Figure 6 is a flowchart illustrating exemplary operation 600 for wireless communication according to several aspects of the present disclosure. Operation 600 may be performed by a network entity, for example, an entity in a core network. According to the aspect, operation 600 may be considered complementary to operations 400 and 500.

[0075]

[0089] Operation 600 is initiated in 602 by communicating with a UE on a first network using a first set of user equipment (UE) certificates.

[0076]

[0090] In 604, the network entity determines that the information must be sent to the UE via the second network using a second set of UE certificates.

[0077]

[0091] In 606, the network entity sends a paging message over the second network indicating that information needs to be sent to the UE over the second network, the paging message including service priority information corresponding to the information that needs to be sent to the UE.

[0078]

[0092] Figure 7 is a flowchart illustrating exemplary operation 700 for wireless communication according to several aspects of the present disclosure. Operation 700 may be performed by a network entity, such as a session management function (SMF), or other entity in the core network. According to the aspect, operation 700 may be considered complementary to operations 400, 500, and 600.

[0079]

[0093] Operation 700 is initiated by receiving a request to establish a physical data unit (PDU) session for a user device (UE) in 702.

[0080]

[0094] In 704, the SMF receives policy configuration information for the PDU session from a second network entity, where the policy configuration information includes service priority information associated with the PDU session. In some cases, the second network entity may have a policy control function (PCF) in the core network.

[0081]

[0095] In step 706, the SMF determines that the information needs to be sent to the UE.

[0082]

[0096] In 708, the SMF determines service priority information corresponding to the information that needs to be sent to the UE, based on the policy configuration information.

[0083]

[0097] In 710, the SMF transmits a signaling to a third network entity for paging the UE for information that needs to be transmitted to the UE, the signaling including instructions for service priority information corresponding to the information that needs to be transmitted to the UE. In some cases, the third network entity may have an Access and Mobility Management Function (AMF).

[0084]

[0098] As described above, aspects of the present disclosure provide a technique that enables a UE to determine whether to respond to a paging message in a second network, which in some cases includes providing service priority information within the paging message that enables the UE to determine whether to establish a connection in the second network in response to the paging message.

[0085]

[0099] For example, in some cases, a UE may communicate with a first network (e.g., via a first RAT, such as 5G) using a first set of proofs. In some cases, the first set of proofs may be stored in a first general-purpose subscriber identification module (USIM). Furthermore, the UE may include a second set of proofs for communicating with a second network (e.g., via a second RAT, such as LTE). In some cases, the second set of proofs may be stored in either the first or second USIM. In some cases, simultaneous communication with both the first and second networks may not be possible (e.g., because the first and second RATs share the same Tx / Rx chain).

[0086]

[0100] In some cases, while communicating with the first network, the UE may receive a paging message for information transmission in the second network, for example, indicating that information needs to be sent to the UE in the second network. Depending on the embodiment, the paging message may include service priority information corresponding to the information transmission, enabling the UE to decide whether or not to respond to the paging message as described above. The service priority information may include a service priority value associated with the information transmission, which can indicate to the UE the priority of the information that needs to be sent to the UE. For example, in some cases, the service priority value may indicate that the information transmission is low priority (for example, or may indicate the type of information transmission that the UE understands as low priority information). In other cases, the service priority value may indicate that the information transmission is high priority (for example, or may indicate the type of information transmission that the UE understands as high priority information). For example, in some cases, IMS voice may be defined as critical, and all other QoS flows may be defined as uncritical. In such cases, when the service priority information in the paging message indicates the service priority value corresponding to the IMS voice data, the UE can understand that the information transmission corresponds to high priority information. Furthermore, service priority information may also include a range of different values ​​to indicate different levels of priority. As described below, the UE may operate in a determined manner based on the service priority value to decide whether or not to respond to a paging message.

[0087]

[0101] In some embodiments, the UE may determine a service priority value (e.g., corresponding to an information transmission) from service priority information, at least in part, based on policy configuration information received from the core network (e.g., via RAN / base stations). In some embodiments, the policy configuration information may indicate how the service priority information should be interpreted to determine the service priority value. For example, in some cases, the policy configuration information may include a set of values, each relating to a different type of information or indicating a different priority related to a different type of information. Thus, the UE may compare the service priority information contained in the paging message with a set of values / different priorities from the policy configuration information to determine the service priority value corresponding to an information transmission.

[0088]

[0102] In some cases, policy configuration information may be received in Open Mobile Alliance (OMA) device management (DM) messages. In other cases, policy configuration information may be received in at least one of the system information in a Radio Resource Control (RRC) message or in an RRC unicast message. In yet other cases, policy configuration information may be received in Non-Access Layer (NAS) messages. For example, in some cases, a NAS message may be received in response to a physical data unit (PDU) session establishment or modification procedure and may include a PDU session establishment or modification response message. Furthermore, in some cases, a NAS message may be received in response to a registration procedure and may include a registration acceptance message.

[0089]

[0103] Depending on the embodiment, once a priority value related to information transmission is determined, the UE decides, at least in part, whether to establish a connection in the second network in response to the paging message. The UE may then take one or more actions, at least in part, based on the decision.

[0090]

[0104] For example, in some cases, the UE may decide not to establish a connection on the second network based on the service priority value, ignore the paging message, and continue communicating with the first network. For example, in some cases, the service priority value may indicate that the information transmission contains low-priority information (e.g., internet traffic). In this case, instead of potentially disrupting critical services on the first network as described above, the UE may choose to ignore the paging message on the second network because the information transmission on the second network is low-priority.

[0091]

[0105] In other cases, the UE may decide to establish a connection in a second network. In this case, the UE may establish a connection in the second network and receive information transmissions in the second network. For example, in some cases, the service priority value may indicate that the information transmission contains high-priority information (e.g., IMS voice). In this case, the UE may choose to transition away from the first network (and potentially interrupt critical services in the first network) and take action to establish a connection in the second network to receive the information transmission.

[0092]

[0106] Aspects of this disclosure will then discuss in more detail the signaling required to page a UE using the techniques described herein. For example, Figure 8 shows an exemplary call flow for page a UE in a current 5G system. In some cases, a UE may be a multi-USIM device capable of communicating with a first network using a first SIM and with a second network using a second SIM (or a second set of proofs for the second network stored in the first SIM), as described above.

[0093]

[0107] Depending on the embodiment, as shown, in step 0, UE812 may be actively communicating with the first network. In step 1a, PCF802 may send a downlink data arrival message to UPF804 indicating that there is an information transmission for UE812 related to the second network. Then, as shown in step 1b, UPF804 sends a downlink data notification message to SMF806 indicating an information transmission for UE812 related to the second network. In step 1c, SMF806 determines that downlink signaling related to the second network (including, for example, an information transmission) needs to be sent to the UE, and in step 2, sends a Namf_Communication_N1N2MessageTransfer message to AMF808 on the N11 interface. The Namf_Communication_N1N2MessageTransfer message may be a standardized message sent between the SMF806 and AMF808, and used to transparently send N1SM NAS messages from the SMF806 to the UE804 and N2SM messages from the SMF806 to the RAN810.

[0094]

[0108] Subsequently, the AMF808 may detect that the UE is in idle mode and, in step 3, send a paging message to the RAN812. The RAN812 may then, in step 4, forward a paging message to the UE indicating that the UE is being paged by a second network. In some cases, the paging message may be sent to the UE812 by the RAN810 over the Uu interface in step 4.

[0095]

[0109] In the current system, the AMF808 may send a paging message to the RAN810 that contains only the paging ID and registration area information related to the second network, and does not contain information about the service corresponding to the paging message. Therefore, when the UE receives a paging message related to the second network in step 4 in Figure 8, the UE may not know the service that triggered the paging, and therefore cannot decide whether or not to respond to the paging message. As described above, if the UE chooses to respond to the paging message, the UE may potentially disrupt critical services related to the first network.

[0096]

[0110] Therefore, as described above, in the case of a multi-USIM UE, it may be advantageous to provide the UE with service priority information in the paging message (for example, using the techniques described above) in order to avoid disruption of critical services in other systems, such as the first network. Having described the general concept of providing service priority information in the paging message above, aspects of this disclosure will now describe in more detail the techniques for configuring service priority in the core network and how service priority should be indicated in the paging message.

[0097]

[0111] Figure 9 shows an exemplary call flow for configuring service priority in the core network 902 according to several embodiments presented herein. As shown, service priority in the core network 902 may be configured during a packet data unit (PDU) establishment / modification procedure / QoS establishment procedure initiated by the UE 904. For example, as shown, in step 1, the UE 904 may send a PDU session establishment request to the AMF 906 for communication in the second network using a second set of proof, as described above. According to the embodiment, the UE may also be communicating in the first network using a first set of proof, as described above.

[0098]

[0112] In step 2, in response to receiving the PDU session establishment request, AMF906 may send an Nsmf_PDUSession_CreateSMContext request to SMF908. The Nsmf_PDUSession_CreateSMContext request may be a standardized message used to establish a new PDU session.

[0099]

[0113] In step 3, during the PDU session establishment procedure, SMF908 may interact with PCF912 to obtain policy configuration information for the PDU session initiated by the UE. PCF912 may include in the policy configuration information the service priority for QoS flows and the service priority for downlink signaling for data network names / slices, as requested in the PDU session establishment request. In some cases, if a new QoS rule is assigned for the PDU session during the PDU session modification procedure, the service priority for the newly assigned QoS flows may be included in the policy and billing control (PCC) rules sent from PCF912 to SMF908.

[0100]

[0114] In step 4, after receiving policy configuration information from PCF912, SMF908 may send an N4 session establishment / modification procedure message to UPF910 that may contain QoS rules for the QoS flow. Furthermore, in some cases, the N4 session establishment / modification procedure message sent to UPF910 may optionally include service priorities for the QoS flow.

[0101]

[0115] Subsequently, as shown in step 5, the SMF908 may send a PDU session establishment response message to the UE904. The PDU session establishment response message may contain policy configuration information for the PDU session initiated by the UE. As stated, the policy configuration information may include the service priority for QoS flows and the service priority for downlink signaling for data network names / slices, as requested in the PDU session establishment request.

[0102]

[0116] Depending on the configuration, if service priorities are configured in the core network 902, the service priority configuration may be used when sending paging messages to the UE 904. The technique for sending paging messages to the UE may depend on whether the UE is in idle mode or RRC inactive mode, as described below.

[0103]

[0117] Figure 10 shows an exemplary call flow for sending a paging message to an idle UE in several embodiments presented herein. As shown, steps 1 and 2 in Figure 10 may be the same as steps 1-3 in Figure 9, where UE 1004 initiates the PDU session establishment / QoS establishment procedure in the second network, and SMF 1008 retrieves service priority (e.g., policy configuration information) from PCF 1012.

[0104]

[0118] After the PDU session / QoS flow is established, the UE1004 may enter idle mode in step 3.

[0105]

[0119] In step 4a, downlink data related to the second network may arrive at UPF1010.

[0106]

[0120] In one embodiment, if in step 4b the SMF1008 did not send the service priority to the UPF1010 during the PDU session establishment procedure (for example, in the N4 message described above), the UPF1010 may send a downlink data notification containing QoS flow information to the SMF1008. In another embodiment, based on the downlink data notification message, the SMF1008 may determine that the information needs to be sent to the UE1004. The SMF1008 may then determine the service priority for the QoS flow identified in the QoS flow information in the downlink data notification, for example, according to the policy configuration information received from the PCF1012.

[0107]

[0121] Depending on the embodiment, if SMF1008 sends a service priority to UPF1010 (for example, in the N4 message described above), UPF1010 determines the service priority for the QoS flow according to the information received from SMF1008. UPF1010 may then include the service priority in the downlink data notification sent to SMF1008 in step 4b.

[0108]

[0122] Furthermore, in some cases, SMF1008 may determine that downlink signaling needs to be sent to UE1004. In this case, in step 4c, SMF determines the service priority for DL ​​signaling according to the policy configuration information received from PCF1012.

[0109]

[0123] Subsequently, SMF1008 may send a signaling to AMF1006 to paging UE1004 for information that needs to be sent to UE1004. In some cases, the signaling may include instructions for service priority information corresponding to the information that needs to be sent to UE1004. For example, as shown in step 5, SMF1008 may send a Namf_Communication_N1N2MessageTransfer message to AMF1006 on the N11 interface, which includes the determined service priority related to the information that needs to be sent to UE1004.

[0110]

[0124] In one embodiment, if the UE is in idle mode and the AMF 1006 decides to send a paging message to the UE, in step 6, the AMF 1006 may send a paging message to the RAN 1014 (for example, a second network) that includes a service priority related to information that needs to be sent to the UE 1004.

[0111]

[0125] Subsequently, in step 7, RAN1014 may send a paging message containing service priority information to UE1004 on the Uu interface. Generally, RAN1014 may communicate with UE1004 and determine (for example, in response to receiving a paging message from AMF1006) that information needs to be sent to UE1004, and may send a paging message to UE1004 indicating that information needs to be sent to UE1004. As stated, the paging message may contain service priority information corresponding to the information that needs to be sent to UE1004.

[0112]

[0126] Depending on the embodiment, the UE may use the service priority information in the paging message to determine, for example, whether to establish a connection with RAN1014 (for example, to receive information that needs to be transmitted) as described above, or whether to completely ignore the paging message. For example, if the paging message contains service priority information corresponding to high priority information, as stated, UE1004 may decide to respond to the paging message and receive information from RAN1014; otherwise, UE1004 may decide to ignore the paging message and not receive any information.

[0113]

[0127] Figure 11 shows an exemplary call flow for sending a paging message to a UE in RRC inactive mode, in several embodiments presented herein. As shown, steps 1-3 in Figure 11 may be the same as steps 1-3 in Figure 9, with UE1104 initiating the PDU session establishment / QoS establishment procedure in the second network and SMF1108 retrieving service priorities (e.g., policy configuration information) from PCF1112.

[0114]

[0128] In step 4 of Figure 11, during the PDU session establishment procedure, SMF1108 may send an Nsmf_PDUSession_CreatSMContext response message to AMF1106. Service priority and DL signaling service priority information regarding the QoS flow, received from PCF1112, may be included in the N2 SM container of the Nsmf_PDUSession_CreatSMContext response message.

[0115]

[0129] In step 5, AMF1106 may forward the N2 SM container to RAN1114 (for example, a second network). In some embodiments, RAN1114 may store the service priority information received in the N2 SM container as the SM context of UE1104.

[0116]

[0130] In step 6, RAN1114 establishes a data radio bearer (DRB) for the PDU session according to standard procedures (for example, as shown in some cases in the RRC reconfiguration information). For example, if UE1104 requests the establishment of a new PDU session, SMF1108 may request RAN1114 to establish a DRB for this PDU session, which may be used to transmit data over the radio interface.

[0117]

[0131] In some cases, a new QoS rule may be assigned for a PDU session in the PDU session modification procedure. In this case, service priority information for the new QoS flow may be sent from PCF1112. SMF1108 may also include the service priority information for the new QoS in an N2 SM container in an N11 message sent to AMF1106, which forwards the N2 SM container to RAN1114. As stated, RAN1114 may store the received service priority information as an SM context in UE1104.

[0118]

[0132] In step 7, UE1114 may enter RRC inactive mode.

[0119]

[0133] In one embodiment, when UE1114 enters RRC inactive mode, if there is information that needs to be sent to the UE in the second network (e.g., downlink data), UPF1110 forwards that information to RAN1114 (e.g., the second network) in step 8. RAN1114 may then determine the service priority for the QoS flow related to the information that needs to be sent to UE1104, according to the service priority information stored as the SM context of UE1104. Subsequently, in step 9, RAN1114 sends a paging message with service priority instructions (e.g., service priority information) to UE1104 on the Uu interface.

[0120]

[0134] Depending on the embodiment, UE1104 may use the service priority information in the paging message to determine, for example, whether to establish a connection with RAN1114 (for example, to receive information that needs to be transmitted) as described above, or whether to completely ignore the paging message. For example, if the paging message contains service priority information corresponding to high priority information, as stated above, UE1104 may decide to respond to the paging message and receive information from RAN1114; otherwise, UE1104 may decide to ignore the paging message and not receive any information.

[0153] The above description is provided so that a person skilled in the art may carry out the various embodiments described herein. Various modifications to these embodiments will be readily apparent to a person skilled in the art, and the general principles defined herein may apply to other embodiments. Accordingly, the claims should not be limited to the embodiments shown herein, but should be given the entire scope consistent with the wording of the claims, where, unless otherwise explicitly stated, a singular reference to an element means "one or more" and not "one unique." Unless otherwise explicitly stated, the term "some" refers to one or more. All structural and functional equivalents of the elements of the various embodiments described throughout this disclosure, known or to a person skilled in the art, are expressly incorporated herein by reference and are included in the claims. Furthermore, nothing disclosed herein, whether such disclosure is expressly presented in the claims or not, is not made public. No claim element should be construed under Section 112(f) of the United States Patent Act unless it is expressly stated using the phrase “means for” or, in the case of a method claim, the “steps for”

[0140]

[0154] The various operations of the methods described above may be performed by any suitable means capable of performing the corresponding functions. These means may include, but are not limited to, a variety of (one or more) hardware and / or software components and / or modules, including circuits, application-specific integrated circuits (ASICs), or processors. Generally, where there are operations shown in the figures, those operations may have corresponding means-plus-function components of similar numbering.

[0141]

[0155] The various exemplary logic blocks, modules, and circuits described in connection with this disclosure may be implemented or run using general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs) or other programmable logic devices (PLDs), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but alternatively, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors working with a DSP core, or any other such configuration.

[0142]

[0156] When implemented in hardware, an exemplary hardware configuration may include a processing system within the wireless node. The processing system may be implemented using a bus architecture. The bus may include any number of interconnecting buses and bridges, depending on the specific application of the processing system and the overall design constraints. The bus may link various circuits to each other, including the processor, machine-readable media, and bus interfaces. The bus interfaces may be used to connect network adapters, in particular, to the processing system via the bus. Network adapters may be used to implement the signal processing functions of the PHY layer. In the case of user terminal 120 (see Figure 1), a user interface (e.g., keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, but these circuits are well known in the art and are therefore not described further. The processor may be implemented using one or more general-purpose and / or dedicated processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits capable of running software. Those skilled in the art will understand how the described functions of the processing system can be best implemented, depending on the specific application and the overall design constraints imposed on the system as a whole.

[0143]

[0157] When implemented in software, functionality may be stored on or transmitted via computer-readable media as one or more instructions or code. Software should be broadly interpreted as meaning instructions, data, or any combination thereof, regardless of the name, such as software, firmware, middleware, microcode, or hardware description language. Computer-readable media includes both computer storage media and communication media, including any medium that enables the transfer of computer programs from one location to another. A processor may be responsible for managing buses and general operations, including the execution of software modules stored on machine-readable storage media. Computer-readable storage media may be coupled to a processor so that the processor can read information from and write information to that storage media. Alternatively, the storage media may be integrated with the processor. For example, machine-readable media may include computer-readable storage media with instructions stored on it, separate from transmission lines, data-modulated carriers, and / or wireless nodes, all of which can be accessed by the processor via a bus interface. Alternatively, or as an addition, machine-readable media, or any part thereof, may be integrated into the processor, such as caches and / or general-purpose register files. Examples of machine-readable storage media may include, as an example, RAM (Random Access Memory), flash memory, ROM (Read-Only Memory), PROM (Programmable Read-Only Memory), EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), registers, magnetic disks, optical disks, hard drives, or other suitable storage media, or any combination thereof. Machine-readable media may be implemented in computer program products.

[0144]

[0158] A software module may consist of a single instruction or a number of instructions, and may be distributed across several different code segments, between different programs, and across multiple storage media. A computer-readable medium may contain several software modules. A software module contains instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a send module and a receive module. Each software module may reside in a single storage device or be distributed across multiple storage devices. For example, when a trigger event occurs, a software module may be loaded from a hard drive into RAM. While a software module is executing, the processor may load some of the instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general-purpose register file for execution by the processor. When the functions of a software module are referred to below, it will be understood that such functions are implemented by the processor when instructions from that software module are executed.

[0145]

[0159] Furthermore, any connection is appropriately referred to as a computer-readable medium. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared (IR), radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. As used herein, disk and disc include compact disc (CD), laserdisc (disc), optical disc (disc), digital versatile disc (disc) (DVD), floppy disk (disk), and Blu-ray (disc), where disk typically reproduces data magnetically and disc optically reproduces data by laser. Thus, in some embodiments, a computer-readable medium may include non-temporary computer-readable medium (e.g., tangible medium). Furthermore, in other embodiments, the computer-readable medium may include a temporary computer-readable medium (e.g., a signal). The above combinations should also be included within the scope of computer-readable mediums.

[0146]

[0160] Accordingly, some embodiments may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium storing (and / or encoding) instructions that are executable by one or more processors for performing the operations described herein, such as the instructions for performing the operations described herein and shown in Figures 4 to 11.

[0147]

[0161] Furthermore, it should be understood that modules and / or other suitable means for performing the methods and techniques described herein may be downloaded and / or otherwise obtained by user terminals and / or base stations where applicable. For example, such devices may be coupled to a server to enable the transfer of means for performing the methods described herein. Alternatively, the various methods described herein may be provided by storage means so that user terminals and / or base stations can obtain the various methods by coupling or providing storage means (e.g., physical storage media such as RAM, ROM, compact disks (CDs), or floppy disks) to the device. Moreover, any other suitable techniques for providing the methods and techniques described herein to a device may be utilized.

[0148]

[0162] It should be understood that the claims are not limited to the exact configuration and components shown above. Various modifications, changes, and variations may be made to the configuration, operation, and details of the methods and apparatus described above without departing from the claims.
