[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

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

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

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, and so on. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access systems include Third Generation Partnership Project (3GPP®) Long Term Evolution (LTE®) systems, LTE-Advanced (LTE-A) systems, code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems, to name a few.

[0004]

[0004] These multiple access technologies are being adopted in various telecommunications standards to provide common protocols that enable different wireless devices to communicate on a city, national, regional, or even global scale. New Radio (e.g., 5G NR) is an example of an emerging telecommunications standard. NR is a set of extensions to the LTE mobile standard promulgated 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 using OFDMA with cyclic prefixes (CPs) on the downlink (DL) and uplink (UL). To these ends, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0005] However, as 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 the telecommunications standards that employ these technologies. Summary of the Invention

[0026]

[0040] For ease of understanding, where possible, the same reference numbers have been used to designate like elements that are common to each of the figures. It is contemplated that elements disclosed in one embodiment may be beneficially utilized on other embodiments without specific recitation.

[0027]

[0041] Aspects of the present disclosure provide an apparatus, method, processing system, and computer-readable medium for multi-SIM user equipment (UE) paging. A multi-USIM UE may be able to communicate with a first network using a first SIM and with a second network using a second SIM (or a second set of credentials for the second network stored in the first SIM). In some cases, communications with the first network and communications with the second network share the same TX / RX chain. In such a case, when the UE receives a paging message related to the second network while communicating with the first network, the UE may tune to the second network to receive information, potentially disrupting critical services in the first network.

[0028]

[0042] Therefore, aspects of the present 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, service priority information indicating a priority associated with information to be received corresponding to the paging message may be included in the paging message. The UE may use the service priority information to determine whether to respond to or ignore the paging message.

[0029]

[0043] The following description provides examples and is not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made in the function and arrangement of the elements described without departing from the scope of the present disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Also, features described with respect to some examples may be combined in some other examples. For example, an apparatus may be implemented or a method may be practiced using any number of aspects described herein. Furthermore, the scope of the present disclosure is intended to cover such apparatuses or methods implemented using other structure, functions, or structure and functions in addition to or other than the various aspects of the present disclosure described herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects.

[0030]

[0044] The techniques described herein may be used for various wireless communication technologies such as 3GPP Long Term Evolution (LTE), LTE-Advanced (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] A CDMA network may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network may implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are parts 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 named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2).

[0032]

[0046] New Radio (NR) is an emerging wireless communication technology under development with the 5G Technology Forum (5GTF). NR access (e.g., 5G NR) may support various wireless communication services, such as enhanced mobile broadband (eMBB), which targets wide bandwidths (e.g., 80 MHz or greater), millimeter wave (mmW), which targets high carrier frequencies (e.g., 25 GHz or greater), massive machine type communications (MTC), which targets non-backward compatible MTC techniques, and / or mission critical, which targets ultra-reliable low-latency communications (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet their respective quality of service (QoS) requirements. Furthermore, these services may coexist in the same subframe.

[0033]

[0047] The techniques described herein may be used for the wireless networks and radio technologies mentioned above, as well as other wireless networks and radio technologies. For clarity, aspects may be described herein using terminology generally associated with 3G and / or 4G wireless technologies, although aspects of the present disclosure may be applied in other generation-based communication systems, such as 5G and beyond, including NR technologies.

[0034]

[0048] FIG. 1 illustrates an example wireless communication network 100 in which aspects of the present disclosure may be implemented. For example, the wireless communication network 100 may be an NR system (e.g., a 5G NR network). As shown in FIG. 1, the wireless communication network 100 may be in communication with a core network 130. The core network 130 may be in communication with one or more BSs 110 and / or UEs 120 via one or more interfaces, as well as with an application server 140, which will be described in further detail below with respect to FIG. 2. As shown in FIG. 1, the UE 120a includes a paging module 114 that may be configured to perform the operations shown in one or more of FIGS. 4-11 as well as other operations described herein for service priority information for multi-SIM UE paging. Additionally, for example, as shown in FIG. 1, the BS 110a also includes a paging module 112 that may be configured to perform the operations shown in one or more of FIGS. 4-11 as well as other operations described herein for service priority information for multi-SIM UE paging.

[0035]

[0049] As shown in FIG. 1, the wireless communication network 100 may include several base stations (BSs) 110 and other network entities. A BS may be a station that communicates with user equipment (UE). Each BS 110 may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to a Node B (NB) coverage area and / or the NB subsystem serving this coverage area, depending on the context in which the term is used. In an NR system, the terms "cell" and BS, next-generation Node B (gNB or gNode B), access point (AP), distributed unit (DU), carrier, or transmit receiving 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, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces, such as direct physical connections, wireless connections, virtual networks, etc., using any suitable transport network.

[0036]

[0050] Generally, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, subcarrier, frequency channel, tone, subband, etc. Each frequency may support a single RAT in a given geographic 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 may provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). A BS for a macrocell may be referred to as a macroBS. A BS for a picocell may be referred to as a picoBS. A BS for a femtocell may be referred to as a femtoBS or a homeBS. In the example shown in FIG. 1, BSs 110a, 110b, and 110c may be macroBSs for macrocells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for a pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.

[0038]

[0052] Wireless communication network 100 may also include relay stations. A relay station is a station that receives data and / or other information transmissions from an upstream station (e.g., a BS or UE) and sends the data and / or other information transmissions to a downstream station (e.g., a UE or BS). A relay station may also be a UE that relays transmissions for other UEs. In the example shown in FIG. 1, relay station 110r may communicate with BS 110a and UE 120r to enable communication between BS 110a and UE 120r. A relay station may also be referred to as a relay BS, a relay, etc.

[0039]

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

[0040]

[0054] The wireless communication network 100 may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.

[0041]

[0055] The network controller 130 may couple to a set of BSs 110 and provide coordination and control for these BSs 110. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (e.g., directly or indirectly) via a wireless backhaul or a wireline backhaul.

[0042]

[0056] The wireless communication network 100 may be part of a radio access network (RAN), which may be in communication with a core network (CN) 140. The CN 140 may then be in communication with an application provider, for example, via an application server (AS) 150. Aspects of the CN 140 are described in more detail below with respect to FIG.

[0043]

[0057] The UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless communications network 100, and each UE may be fixed or mobile. A UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premises equipment (CPE), cellular phone, smartphone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, appliance, medical device or equipment, biometric sensor / device, wearable device such as smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.), entertainment device (e.g., music device, video device, satellite radio, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. A UE includes, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, a location tag, etc. that may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs may 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 partition the system bandwidth into multiple (K) orthogonal subcarriers, also commonly referred to as tones, bins, etc. Each subcarrier may be modulated with data. Generally, modulation symbols are sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may depend on the system bandwidth. For example, the subcarrier spacing may be 15 kHz, and the minimum resource allocation (called a “resource block” (RB)) may be 12 subcarriers (or 180 kHz). Thus, the nominal fast Fourier transform (FFT) size may 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 may also be partitioned 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 transmission time interval (TTI) or packet duration is a 1 ms subframe. In NR, a 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 spacing. An NR RB is 12 consecutive frequency subcarriers. NR may support a base subcarrier spacing of 15 kHz, and other subcarrier spacings may be defined relative to the base subcarrier spacing, such as 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. Symbol length and slot length scale with the subcarrier spacing. CP length also depends on the subcarrier spacing.

[0045]

[0059] NR utilizes OFDM with CP on the uplink and downlink and may include support for half-duplex operation using TDD. Beamforming may be supported, and beam directions may be dynamically configured. MIMO transmission with precoding may also be supported. In some examples, MIMO configuration in the DL may support up to eight transmit antennas with multi-layer DL transmission of up to eight streams and up to two streams per UE. In some examples, multi-layer transmission with up to two streams per UE may be supported. Multiple cell aggregation may be supported with up to eight serving cells.

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

[0047]

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

[0048]

[0062] In Figure 1, a solid line with double arrows indicates a desired transmission on the downlink and / or uplink between a UE and a serving BS, which is the BS designated to serve that UE. A thin dashed line with double arrows indicates a potentially interfering transmission between a UE and a BS.

[0049]

[0063] 2 is a block diagram illustrating an example architecture of a CN 200 (e.g., such as the CN 140 in FIG. 1) in communication with a RAN 224 and an AS 202 (e.g., such as the AS 150 in FIG. 1) in accordance with certain aspects of the present disclosure. As shown in FIG. 2, the example architecture includes the CN 200, the RAN 224, a UE 222, and a data network (DN) 228 (e.g., operator services, Internet access, or third-party services).

[0050]

[0064] The CN 200 may host core network functions. The CN 200 may be deployed centrally. The CN 200 functions may be offloaded (e.g., to Advanced Wireless Services (AWS)) to handle peak capacity. As shown in FIG. 2, the exemplary CN 200 may be implemented by one or more network entities performing 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, a Unified 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), a Unified Data Repository (UDR), a 5G-Equipment Identity Register (5G-EIR), and / or a Security Edge Protection Proxy (SEPP).

[0051]

[0065] The AMF 218 provides the following functions (some or all of the AMF functions may be supported in one or more instances of the AMF): termination of the RAN Control Plane (CP) interface (N2), termination of the Non-Access Stratum (NAS) (e.g., N1), NAS ciphering and integrity protection, registration management, connection management, reachability management, mobility management, lawful intercept (for AMF events and interface to L1 systems), transport for session management (SM) messages between the UE 222 and the SMF 220, transparent proxy for routing SM messages, access authentication, access authorization, transport for short message service (SMS) messages between the UE 222 and the SMS Function (SMSF), Security Anchor Function (SEAF), and so on. The RAN 224 may include a Security Context Management (SCM) for receiving keys from the SEAF that it uses to derive access network specific keys, a Location Services Management (LSM) for restricted services, transport for location services messages between the UE 222 and the Location Management Function (LMF), and also between the RAN 224 and the LMF, EPS bearer ID allocation for interworking with Evolved Packet Services (EPS), and / or UE mobility event notification, and / or other functions.

[0052]

[0066] The SMF 220 may support session management (e.g., session establishment, modification, and release), UE IP address allocation and management, Dynamic Host Configuration Protocol (DHCP) functions, termination of NAS signaling related to session management, downlink data notification, and traffic steering configuration for the UPF for appropriate traffic routing. The UPF 226 may support packet routing and forwarding, packet inspection, quality of service (QoS) processing, external protocol data unit (PDU) session points of interconnection to the DN 228, and anchor points for intra- and inter-RAT mobility. The PCF 210 may support a unified policy framework that provides policy rules for controlling protocol functions and / or accessing subscription information for policy decisions in the UDR. The AUSF 216 may act as an authentication server. The UDM 212 may support authentication and key agreement (AKA) credential generation, user identity processing, access authorization, and subscription management. The NRF 208 may support service discovery functions and maintain NF profiles and available NF instances. The NSSF may support selecting a network slice instance to serve the UE 222, determining allowable network slice selection assistance information (NSSAI), and / or determining an AMF set to be used to serve the UE 222. Additionally, in some cases, the SMF 220, the UPF 226, the PCF 210, the AMF 218, and the RAN 224 may be configured to perform operations for service priority information for multi-SIM UE paging in accordance with certain aspects described herein.

[0053]

[0067] The NEF 206 may support exposure of capabilities and events, secure provision of information from external applications to the 3GPP network, and internal / external information translation. The AF 214 may support application influence on traffic routing, access to the NEF 206, and / or interaction with a policy framework for policy control.

[0054]

[0068] 3 illustrates example components of a BS 110 and a UE 120 (e.g., in the wireless communications network 100 of FIG. 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 the UE 120 and / or the antenna 334, processors 320, 330, 338, and / or controller / processor 340 of the BS 110 may be used to perform various techniques and methods described herein. For example, as shown in FIG. 3, the controller / processor 340 of the BS 110 includes a paging module 341 that may be configured to perform the operations shown in one or more of FIGS. 4-11 as well as other operations described herein for service priority information for multi-SIM UE paging. Additionally, for example, as shown in FIG. 3, the controller / processor 380 of the UE 120 also includes a paging module 381 that may be configured to perform the operations shown in one or more of FIGS. 4-11, as well as other operations described herein for service priority information for multi-SIM UE paging.

[0055]

[0069] At the BS 110, the transmit processor 320 may receive data from the data source 312 and control information from the controller / processor 340. The control information may be for a Physical Broadcast Channel (PBCH), a Physical Control Format Indicator Channel (PCFICH), a Physical Hybrid ARQ Indicator Channel (PHICH), a Physical Downlink Control Channel (PDCCH), a Group Common PDCCH (GC PDCCH), etc. The data may be for a Physical Downlink Shared Channel (PDSCH), etc. The processor 320 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 320 may also generate reference symbols, such as for a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Cell-Specific Reference Signal (CRS). The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, and / or reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) 332a through 332t. Each modulator 332 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 332a through 332t may be transmitted via antennas 334a through 334t, respectively.

[0056]

[0070] At the UE 120, the antennas 352a through 352r may receive downlink signals from the BS 110 and may provide received signals to respective transceiver demodulators (DEMODs) 354a through 354r. Each demodulator 354 may condition (e.g., filter, amplify, downconvert, and digitize) its respective received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 356 may obtain received symbols from all demodulators 354a through 354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols and provide decoded data for the UE 120 to a data sink 360 and decoded control information to a controller / processor 380.

[0057]

[0071] On the uplink, at the UE 120, a transmit processor 364 may receive and process data from a data source 362 (e.g., for the Physical Uplink Shared Channel (PUSCH)) and control information from a controller / processor 380 (e.g., for the Physical Uplink Control Channel (PUCCH)). The transmit processor 364 may also generate reference symbols for a reference signal (e.g., for a Sounding Reference Signal (SRS)). The symbols from the transmit processor 364 may be precoded by a TX MIMO processor 366 if applicable, further processed by demodulators 354a through 354r in the transceiver (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the BS 110, uplink signals from the UE 120 may be received by the antennas 334, processed by a modulator 332, detected by a MIMO detector 336 if applicable, and further processed by a receive processor 338 to obtain decoded data and control information sent by the UE 120. The receive processor 338 may provide the decoded data to a data sink 339 and the decoded control information to a controller / processor 340 .

[0058]

[0072] Controllers / processors 340 and 380 may direct operation at BS 110 and UE 120, respectively. Controller / processor 340 and / or other processors and modules at BS 110 may perform or direct execution of processes for the techniques described herein. Memories 342 and 382 may store data and program codes for BS 110 and UE 120, respectively. Scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0059] Exemplary Service Priority Information for Multi-SIM User Equipment Paging

[0073] A user equipment (UE), such as the UE 120, may include two or more subscriber identity modules (SIMs) and / or universal subscriber identity modules (USIMs). A UE with two or more SIMs may be referred to as a multi-SIM device. In this disclosure, SIM may refer to a SIM or a USIM. Each SIM may also include a unique international mobile subscriber identity (IMSI) and service subscription information (e.g., a UE service certificate). Each SIM may be configured to operate in a specific radio access technology (RAT), which allows the UE to communicate using different RATs using 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), where both SIMs use a single RF chain to transmit and receive communications.

[0061]

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

[0062]

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

[0063]

[0077] 4 is a flow diagram illustrating example operations 400 for wireless communication in accordance with certain aspects of the present disclosure. The operations 400 may be performed by a first wireless node, such as a UE (e.g., a UE 120 in the wireless communication network 100).

[0064]

[0078] The operations 400 may be implemented as software components executing and operating on one or more processors (e.g., controller / processor 380 of FIG. 3). Further, transmission and reception of signals by the UE in operations 400 may be enabled by, for example, one or more antennas (e.g., antenna 352 of FIG. 3). In some aspects, transmission and / or reception of signals by the UE may be implemented via a bus interface of one or more processors (e.g., controller / processor 380) that acquire and / or output the signals.

[0065]

[0079] The operations 400 begin by communicating with a first network using a first set of credentials, wherein the UE includes a second set of credentials associated with a second network. In some cases, the first set of credentials is stored in a first Universal Subscriber Identity Module (USIM). Further, in some cases, the second set of credentials is stored in one of the first USIM or the second USIM.

[0066]

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

[0067]

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

[0068]

[0082] At 408, the UE determines whether to establish a connection in the second network in response to the paging message based at least in part on the service priority value.

[0069]

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

[0070]

[0084] 5 is a flow diagram illustrating example operations 500 for wireless communication in accordance with certain aspects of the present disclosure. The operations 500 may be performed by a network entity, e.g., an entity in a RAN. According to aspects, the operations 500 may be considered complimentary to the operations 400 performed by a UE.

[0071]

[0085] The operations 500 begin, at 502, by communicating with a user equipment (UE).

[0072]

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

[0073]

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

[0074]

[0088] 6 is a flow diagram illustrating example operations 600 for wireless communication in accordance with certain aspects of the present disclosure. The operations 600 may be performed by a network entity, for example, an entity in a core network. According to aspects, the operations 600 may be considered complimentary to the operations 400 and 500.

[0075]

[0089] The operations 600 begin, at 602, by communicating with a user equipment (UE) in a first network using a first set of UE credentials.

[0076]

[0090] At 604, the network entity determines that information needs to be transmitted to the UE via a second network using a second set of UE credentials.

[0077]

[0091] At 606, the network entity transmits a paging message via the second network indicating that information needs to be transmitted to the UE via the second network, wherein the paging message includes service priority information corresponding to the information that needs to be transmitted to the UE.

[0078]

[0092] 7 is a flow diagram illustrating example operations 700 for wireless communication according to some aspects of the present disclosure. The operations 700 may be performed by a network entity, e.g., an entity in a core network, such as a session management function (SMF). According to an aspect, the operations 700 may be considered complimentary to the operations 400, 500, and 600.

[0079]

[0093] The operations 700 begin, at 702, by receiving a physical data unit (PDU) session establishment request for a user equipment (UE).

[0080]

[0094] At 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 comprise a Policy Control Function (PCF) in the core network.

[0081]

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

[0082]

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

[0083]

[0097] At 710, the SMF sends signaling to a third network entity to page the UE for information that needs to be sent to the UE, where the signaling includes an indication of service priority information that corresponds to the information that needs to be sent to the UE. In some cases, the third network entity may comprise an Access and Mobility Management Function (AMF).

[0084]

[0098] As described above, aspects of the present disclosure provide techniques that enable a UE to determine whether to respond to a paging message in a second network, which in some cases includes providing service priority information in 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 credentials. In some cases, the first set of credentials may be stored in a first Universal Subscriber Identity Module (USIM). Additionally, the UE may include a second set of credentials for communicating in a second network (e.g., via a second RAT, such as LTE). In some cases, the second set of credentials may be stored in one of the first USIM or the second USIM. In some cases, the UE may not be capable of simultaneous communication with both the first network and the second network (e.g., because the first RAT and the second RAT 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 transmitted to the UE in the second network. According to an aspect, the paging message may include service priority information corresponding to the information transmission to enable the UE to determine whether 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 may indicate to the UE the priority of the information that needs to be transmitted to the UE. For example, in some cases, the service priority value may indicate that the information transmission is low priority (e.g., or may indicate a 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 (e.g., or may indicate a type of information transmission that the UE understands as high priority information). For example, in some cases, IMS voice may be defined as important, and all other QoS flows may be defined as unimportant. In such a case, when the service priority information in the paging message indicates a service priority value corresponding to IMS voice data, the UE may understand that the information transmission corresponds to high priority information. Furthermore, the service priority information may also include different value ranges to indicate different levels of priority. As described below, the UE may act in a determined manner based on the service priority value to select whether to respond to the paging message.

[0087]

[0101] According to aspects, the UE may determine a service priority value (e.g., corresponding to an information transmission) from service priority information based at least in part on policy configuration information received from a core network (e.g., via a RAN / base station). According to aspects, the policy configuration information may indicate how to interpret the service priority information to determine the service priority value. For example, in some cases, the policy configuration information may include a set of values, each associated with a different type of information or indicating different priorities associated with the different types of information. Thus, the UE may compare the service priority information included in the paging message with the value / set of different priorities from the policy configuration information to determine a service priority value corresponding to the information transmission.

[0088]

[0102] In some cases, the policy configuration information may be received in an Open Mobile Alliance (OMA) Device Management (DM) message. In other cases, the policy configuration information may be received in at least one of a system information in a Radio Resource Control (RRC) message or an RRC unicast message. In still other cases, the policy configuration information may be received in a Non-Access Stratum (NAS) message. For example, in some cases, the NAS message may be received in response to a Physical Data Unit (PDU) session establishment or modification procedure and may comprise a PDU Session Establishment or Modification Response message. Furthermore, in some cases, the NAS message may be received in response to a registration procedure and may comprise a Registration Accept message.

[0089]

[0103] According to an aspect, once the priority value associated with the information transmission is determined, the UE determines whether to establish a connection in the second network in response to the paging message based at least in part on the service priority value. The UE may then take one or more actions based at least in part on the determination.

[0090]

[0104] For example, in some cases, the UE may decide not to establish a connection in 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 includes low priority information (e.g., Internet traffic). In this case, instead of potentially disrupting important services in the first network as described above, the UE may elect to take action to ignore the paging message in the second network because the information transmission in the second network is low priority.

[0091]

[0105] In other cases, the UE may decide to establish a connection in the second network. In this case, the UE may establish a connection in the second network and receive the information transmission in the second network. For example, in some cases, the service priority value may indicate that the information transmission includes high-priority information (e.g., IMS voice). In this case, the UE may elect 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 the present disclosure will now be discussed in more detail regarding the signaling required to page a UE using the techniques described herein. For example, Figure 8 shows an example call flow for paging a UE in a current 5G system. In some cases, the 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 credentials for the second network stored in the first SIM), as described above.

[0093]

[0107] According to an aspect, as shown, in step 0, the UE 812 may be actively communicating with a first network. In step 1a, the PCF 802 may send a Downlink Data Arrival message to the UPF 804 indicating that there is an information transmission for the UE 812 associated with the second network. Thereafter, as shown in step 1b, the UPF 804 sends a Downlink Data Notification message to the SMF 806 indicating the information transmission for the UE 812 associated with the second network. In step 1c, the SMF 806 determines that downlink signaling associated with the second network (e.g., including the information transmission) needs to be sent to the UE and sends a Namf_Communication_N1N2MessageTransfer message to the AMF 808 over the N11 interface in step 2. The Namf_Communication_N1N2MessageTransfer message may be a standardized message sent between the SMF 806 and the AMF 808 and used to transparently send N1SM NAS messages from the SMF 806 to the UE 804 and to transparently send N2SM messages from the SMF 806 to the RAN 810.

[0094]

[0108] The AMF 808 may then detect that the UE is in idle mode and send a paging message to the RAN 812 in step 3. The RAN 812 may then forward the paging message to the UE indicating that the UE is being paged by the second network in step 4. In some cases, the paging message may be sent by the RAN 810 to the UE 812 over the Uu interface in step 4.

[0095]

[0109] In current systems, the AMF 808 may send a paging message to the RAN 810 that includes only paging ID and registration area information associated with the second network, but does not include information about the service corresponding to the paging message. Thus, when the UE receives a paging message associated with the second network in step 4 in Figure 8, the UE may not know the service that triggered the paging and therefore cannot make a decision whether to respond to the paging message. As described above, if the UE chooses to respond to the paging message, the UE may potentially disrupt important services associated with the first network.

[0096]

[0110] Thus, as mentioned above, for a multi-USIM UE, it may be advantageous to provide service priority information to the UE in a paging message (e.g., using the techniques described above) to avoid interruption of important services in other systems, such as the first network. Having described above the general concept of providing service priority information in a paging message, aspects of the present disclosure next describe in more detail techniques for configuring service priority in the core network and how service priority should be indicated in a paging message.

[0097]

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

[0098]

[0112] In step 2, in response to receiving the PDU session establishment request, the AMF 906 may send an Nsmf_PDUSession_CreateSMContext request to the SMF 908. 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, the SMF 908 may interact with the PCF 912 to obtain policy configuration information for the PDU session initiated by the UE. The PCF 912 may include, in the policy configuration information, the service priority for the QoS flow and the service priority for downlink signaling for the data network name / slice requested in the PDU session establishment request. In some cases, if new QoS rules are allocated for the PDU session during the PDU session modification procedure, the service priority for the newly allocated QoS flow may be included in the Policy and Charging Control (PCC) rules sent from the PCF 912 to the SMF 908.

[0100]

[0114] In step 4, after receiving the policy configuration information from the PCF 912, the SMF 908 may send an N4 Session Establishment / Modification Procedure message, which may include the QoS rules for the QoS flow, to the UPF 910. Additionally, in some cases, the N4 Session Establishment / Modification Procedure message sent to the UPF 910 may optionally include a service priority for the QoS flow.

[0101]

[0115] Thereafter, as shown in step 5, the SMF 908 may send a PDU Session Establishment Response message to the UE 904. The PDU Session Establishment Response message may include policy configuration information for the PDU session initiated by the UE. As mentioned, the policy configuration information may include the service priority for the QoS flow and the service priority for downlink signaling for the data network name / slice requested in the PDU Session Establishment Request.

[0102]

[0116] According to an aspect, once service priority is configured in the core network 902, the service priority configuration may be used when sending a paging message to the UE 904. The technique for sending the paging message to the UE may depend on whether the UE is in an idle mode or an RRC inactive mode, as described below.

[0117] 10 illustrates an example call flow for transmitting a paging message to a UE in idle mode in accordance with certain aspects presented herein. As shown, steps 1 and 2 of FIG. 10 may be the same as steps 1-3 in FIG. 9, in which the UE 1004 initiates a PDU session establishment / QoS establishment procedure in the second network and the SMF 1008 retrieves service priorities (e.g., policy configuration information) from the PCF 1012.

[0104]

[0118] After the PDU session / QoS flow is established, the UE 1004 may enter idle mode in step 3.

[0105]

[0119] In step 4a, downlink data associated with the second network may arrive at the UPF 1010.

[0106]

[0120] According to an aspect, in step 4b, if the SMF 1008 did not send a service priority to the UPF 1010 during the PDU session establishment procedure (e.g., in the N4 message described above), the UPF 1010 may send a downlink data notification including the QoS flow information to the SMF 1008. According to an aspect, based on the downlink data notification message, the SMF 1008 may determine that information needs to be sent to the UE 1004. The SMF 1008 may then determine a service priority for the QoS flow identified in the QoS flow information in the downlink data notification, for example, according to the received policy configuration information from the PCF 1012.

[0107]

[0121] According to an aspect, if the SMF 1008 sent a service priority to the UPF 1010 (e.g., in the N4 message described above), the UPF 1010 determines the service priority for the QoS flow according to the information received from the SMF 1008. The UPF 1010 may then include the service priority in the downlink data notification sent to the SMF 1008 in step 4b.

[0108]

[0122] Furthermore, in some cases, the SMF 1008 may determine that downlink signaling needs to be sent to the UE 1004. In this case, in step 4c, the SMF determines the service priority for the DL signaling according to the received policy configuration information from the PCF 1012.

[0109]

[0123] The SMF 1008 may then send signaling to the AMF 1006 to page the UE 1004 for information that needs to be sent to the UE 1004. In some cases, the signaling may include an indication of service priority information that corresponds to the information that needs to be sent to the UE 1004. For example, as shown in step 5, the SMF 1008 may send a Namf_Communication_N1N2MessageTransfer message to the AMF 1006 over the N11 interface, including the determined service priority associated with the information that needs to be sent to the UE 1004.

[0110]

[0124] According to an aspect, if the UE is in idle mode and the AMF 1006 determines to send a paging message to the UE, in step 6, the AMF 1006 may send a paging message to the RAN 1014 (e.g., a second network) including a service priority related to information that needs to be sent to the UE 1004.

[0111]

[0125] Thereafter, in step 7, the RAN 1014 may send a paging message with service priority information to the UE 1004 over the Uu interface. Generally, the RAN 1014 may communicate with the UE 1004 and determine that information needs to be sent to the UE 1004 (e.g., in response to receiving a paging message from the AMF 1006) and may send a paging message to the UE 1004 indicating that the information needs to be sent to the UE 1004. As mentioned, the paging message may include service priority information corresponding to the information that needs to be sent to the UE 1004.

[0112]

[0126] According to an aspect, the UE may use the service priority information in the paging message to determine whether to establish a connection with the RAN 1014 (e.g., to receive information that needs to be transmitted) or whether to ignore the paging message entirely, e.g., as described above. For example, as mentioned, if the paging message includes service priority information that corresponds to high priority information, the UE 1004 may decide to respond to the paging message and receive information from the RAN 1014; otherwise, the UE 1004 may decide to ignore the paging message and not receive the information.

[0113]

[0127] 11 illustrates an example call flow for transmitting a paging message to a UE in an RRC inactive mode in accordance with certain aspects presented herein. As shown, steps 1-3 of FIG. 11 may be the same as steps 1-3 in FIG. 9, in which a UE 1104 initiates a PDU session establishment / QoS establishment procedure in a second network and an SMF 1108 retrieves service priorities (e.g., policy configuration information) from a PCF 1112.

[0114]

[0128] 11, during the PDU session establishment procedure, the SMF 1108 may send an Nsmf_PDUSession_CreateSMContext response message to the AMF 1106. The service priority and DL signaling service priority information for the QoS flow received from the PCF 1112 may be included in the N2 SM container of the Nsmf_PDUSession_CreateSMContext response message.

[0115]

[0129] In step 5, the AMF 1106 may forward the N2 SM container to the RAN 1114 (e.g., a second network). According to an aspect, the RAN 1114 may store the service priority information received in the N2 SM container as an SM context of the UE 1104.

[0116]

[0130] In step 6, the RAN 1114 establishes a data radio bearer (DRB) for the PDU session according to standard procedures (e.g., in some cases, as indicated in the RRC reconfiguration information). For example, if the UE 1104 requests to establish a new PDU session, the SMF 1108 may request the RAN 1114 to establish a DRB for this PDU session that can be used to transmit data over the air interface.

[0117]

[0131] In some cases, new QoS rules may be allocated for a PDU session in a PDU session modification procedure. In this case, service priority information for the new QoS flow may be sent from the PCF 1112. The SMF 1108 may also include the service priority information for the new QoS in an N2 SM container in an N11 message sent to the AMF 1106, which forwards the N2 SM container to the RAN 1114. As mentioned, the RAN 1114 may store the received service priority information as an SM context for the UE 1104.

[0118]

[0132] In step 7, the UE 1114 may enter an RRC inactive mode.

[0119]

[0133] According to an aspect, when the UE 1114 enters the RRC inactive mode, if there is information (e.g., downlink data) that needs to be transmitted to the UE in the second network, the UPF 1110 forwards the information to the RAN 1114 (e.g., the second network) in step 8. The RAN 1114 may then determine a service priority for the QoS flow associated with the information that needs to be transmitted to the UE 1104 according to the service priority information stored as the SM context of the UE 1104. Thereafter, in step 9, the RAN 1114 sends a paging message with an indication of the service priority (e.g., the service priority information) to the UE 1104 over the Uu interface.

[0120]

[0134] According to an aspect, the UE 1104 may use the service priority information in the paging message to determine whether to establish a connection with the RAN 1114 (e.g., to receive information that needs to be transmitted) or whether to ignore the paging message entirely, e.g., as described above. For example, as mentioned, if the paging message includes service priority information that corresponds to high priority information, the UE 1104 may decide to respond to the paging message and receive information from the RAN 1114; otherwise, the UE 1104 may decide to ignore the paging message and not receive the information.

[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 various hardware and / or software components and / or modules, including, but not limited to, circuits, application specific integrated circuits (ASICs), or processors. Generally, where there are operations illustrated in figures, those operations may have corresponding counterpart means-plus-function components with similar numbering.

[0141]

[0155] The various example logic blocks, modules, and circuits described in connection with this disclosure may be implemented or performed using a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device (PLD), 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. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0142]

[0156] When implemented in hardware, an exemplary hardware configuration may comprise a processing system in a wireless node. The processing system may be implemented using a bus architecture. The bus may include any number of interconnected buses and bridges, depending on the particular application and overall design constraints of the processing system. The bus may link various circuits together, including processors, machine-readable media, and bus interfaces. The bus interface may be used to connect a network adapter, among other things, to the processing system via the bus. The network adapter may be used to implement PHY layer signal processing functions. In the case of a user terminal 120 (see FIG. 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, power management circuits, etc., which are well known in the art and therefore will not be described further. The processor may be implemented using one or more general-purpose and / or special-purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits capable of executing software. Those skilled in the art will understand how to best implement the described functionality for a processing system depending on the particular application and the overall design constraints imposed on the overall system.

[0143]

[0157] If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Software should be broadly interpreted to mean instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. Computer-readable media includes both computer storage media and communication media, including any medium that enables transfer of a computer program from one place to another. A processor may be responsible for managing a bus and general processing, including the execution of software modules stored on the machine-readable storage medium. The computer-readable storage medium may be coupled to the processor such that the processor can read information from, and write information to, the storage medium. Alternatively, the storage medium may be integral to the processor. By way of example, the machine-readable medium may include a transmission line, a carrier wave modulated by data, and / or a computer-readable storage medium with instructions stored thereon that is separate from a wireless node, all of which may be accessed by the processor via a bus interface. Alternatively, or additionally, the machine-readable medium, or any portion thereof, may be integrated into the processor, such as may be a cache and / or general-purpose register file. Examples of machine-readable storage media may include, by way of example, RAM (random access memory), flash memory, ROM (read-only memory), PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), registers, magnetic disks, optical disks, hard drives, or other suitable storage media, or any combination thereof. The machine-readable medium may be embodied in a computer program product.

[0144]

[0158] A software module may comprise a single instruction, or many instructions, and may be distributed over several different code segments, among different programs, and across multiple storage media. A computer-readable medium may comprise 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 transmitting module and a receiving module. Each software module may reside in a single storage device or be distributed across multiple storage devices. As an example, a software module may be loaded into RAM from a hard drive when a trigger event occurs. During execution of a software module, a 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 referring below to the functionality of a software module, it will be understood that such functionality is implemented by the processor when executing instructions from that software module.

[0145]

[0159] Also, any connection is properly termed 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, the 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 discs (CDs), laser discs, optical discs, digital versatile discs (DVDs), floppy discs, and Blu-ray discs, where disks typically reproduce data magnetically and discs reproduce data optically with lasers. Thus, in some aspects computer-readable medium may comprise non-transitory computer-readable medium (e.g., tangible media). Furthermore, in other aspects, computer-readable media may comprise transitory computer-readable media (eg, a signal). Combinations of the above should also be included within the scope of computer-readable media.

[0146]

[0160] Accordingly, some aspects may comprise a computer program product for performing the operations presented herein. For example, such a computer program product may comprise a computer-readable medium having stored thereon (and / or encoded thereon) instructions executable by one or more processors to perform the operations described herein, e.g., instructions for performing the operations described herein and illustrated in Figures 4-11.

[0147]

[0161] Furthermore, it should be appreciated that modules and / or other suitable means for performing the methods and techniques described herein may be downloaded and / or otherwise obtained by a user terminal and / or base station, where applicable. For example, such devices may be coupled to a server to facilitate the transfer of means for performing the methods described herein. Alternatively, the various methods described herein may be provided by a storage means (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or floppy disk, etc.) such that the user terminal and / or base station can obtain the various methods upon coupling or providing the storage means to the device. Moreover, any other suitable technique for providing the methods and techniques described herein to a device may be utilized.
