[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of and priority to PCT Application No. PCT / CN2019 / 090297, filed on June 6, 2019, which is assigned to the assignee of this application and is hereby expressly incorporated herein by reference as if fully set forth below and for all applicable purposes.

[0003] Public domain

[0004] 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.

[0005] Related technical description

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, etc. 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 just a few.

[0007] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhancement set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards using OFDMA with cyclic prefix (CP) on downlink (DL) and uplink (UL). To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0008] However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

[0046] Detailed Description

[0047] Various aspects of the present disclosure provide apparatus (devices), methods, processing systems, and computer-readable media for paging of multi-SIM user equipment (UE). A multi-USIM UE may be able to communicate with a first network using a first SIM and communicate with a second network using a second SIM (or a second set of credentials for a second network stored in the first SIM). In some cases, communications with the first network and the second network share the same TX / RX chain. In such cases, when the UE receives a paging message associated with the second network while communicating with the first network, the UE may tune to the second network to receive information, thereby potentially interrupting critical services in the first network.

[0048] Therefore, various aspects of the present disclosure provide techniques for allowing a UE to decide whether to respond to a paging message in a second network. For example, in some cases, service priority information may be included in a paging message, the service priority information indicating a priority associated with information corresponding to the paging message to be received. The UE may use the service priority information to decide whether to respond to or ignore the paging message.

[0049] The following description provides examples rather than limiting the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various examples may appropriately omit, replace, or add various procedures or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. Moreover, the features described with reference to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such equipment or methods practiced using other structures, functionalities, or structures and functionalities as supplements to the various aspects of the present disclosure set forth herein or in addition. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of the claims. The wording "exemplary" is used herein to mean "used as an example, instance, or explanation". Any aspect described herein as "exemplary" need not be interpreted as being superior to or superior to other aspects.

[0050] The techniques described herein may be used for various wireless communication technologies, such as 3GPP Long Term Evolution (LTE), Advanced 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.

[0051] 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), IEEE802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are parts of Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions 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 named "3rd Generation Partnership Project 2" (3GPP2).

[0052] New Radio (NR) is an emerging wireless communication technology being developed in collaboration with the 5G Technical Forum (5GTF). NR access (e.g., 5G NR) can support a variety of wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80MHz or higher), millimeter wave (mmW) targeting high carrier frequency (e.g., 25GHz or higher), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical services targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet corresponding quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.

[0053] 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, although various aspects may be described herein using terms typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0054] Figure 1 An example wireless communication network 100 is illustrated in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a NR system (e.g., a 5G NR network). Figure 1 As shown, 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 and with an application server 140 via one or more interfaces, as described below with respect to Figure 2 discussed in more detail. Figure 1 As shown, UE 120a includes a paging module 114, which can be configured to perform Figure 4-11 The operations described in one or more of and other operations described herein regarding service priority information for multi-SIM UE paging. Additionally, for example, Figure 1 As shown, BS 110a also includes a paging module 112, which can be configured to perform Figure 4-11 The operations illustrated in one or more of and other operations described herein regarding service priority information for multi-SIM UE paging.

[0055] like Figure 1As illustrated in , the wireless communication network 100 may include several base stations (BS) 110 and other network entities. The BS may be a station that communicates with a user equipment (UE). Each BS 110 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a B node (NB) and / or a NB subsystem serving the coverage area, depending on the context in which the term is used. In the NR system, the term "cell" and BS, next generation B node (gNB or g B node), access point (AP), distributed unit (DU), carrier, or transmission reception point (TRP) may be used interchangeably. In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move according to the location of the mobile BS. In some examples, the BS 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, or analogs using any suitable transmission networks).

[0056] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, subcarrier, frequency channel, frequency modulation, 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.

[0057] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a residence, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in FIG. 1 , BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for 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.

[0058] The wireless communication network 100 may also include a relay station. A relay station is a station that receives transmissions of data and / or other information from an upstream station (e.g., a BS or a UE) and sends transmissions of the data and / or other information to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown in , a relay station 110r may communicate with a BS 110a and a UE 120r to facilitate communication between the BS 110a and the UE 120r. A relay station may also be referred to as a relay BS, a relay, or the like.

[0059] The 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 the wireless communication network 100. For example, a macro BS may have a high transmit power level (e.g., 20 watts), while a pico BS, a femto BS, and a relay may have a lower transmit power level (e.g., 1 watt).

[0060] The wireless communication network 100 may support synchronous or asynchronous operation. For synchronous operation, each BS may have similar frame timing, and transmissions from different BSs may be roughly aligned in time. For asynchronous operation, each BS 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.

[0061] A network controller 130 may couple to a set of BSs 110 and provide coordination and control for the BSs 110. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0062] The wireless communication network 100 may be part of a radio access network (RAN) that may be in communication with a core network (CN) 140. The CN 140 may in turn be in communication with an application provider (eg, via an application server (AS) 150). Various aspects of the CN 140 are described below with respect to Fig.12 Let's describe it in more detail.

[0063] UE 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless communication network 100, and each UE may be stationary or mobile. UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premises equipment (CPE), cellular phone, smart phone, 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 medical 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.), transportation component or sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate via wireless or wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node can provide connectivity for or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0064] 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 multiple (K) orthogonal subcarriers, which are also often referred to as frequency modulation, frequency bins, etc. Each subcarrier can be modulated with data. In general, modulation symbols are sent in the frequency domain for OFDM and in the time domain for 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 spacing of subcarriers can be 15kHz, and the minimum resource allocation (called a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be divided into subbands. For example, a subband may cover 1.08 MHz (e.g., 6 RBs), and for a system bandwidth of 1.25, 2.5, 5, 10, or 20 MHz, there may be 1, 2, 4, 8, or 16 subbands, 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. NR RBs are 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, e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. The symbol and slot lengths scale with the subcarrier spacing. The CP length also depends on the subcarrier spacing.

[0065] NR may utilize OFDM with CP on both uplink and downlink and include support for half-duplex operation using TDD. Beamforming may be supported and beam directions may be dynamically configured. MIMO transmissions with precoding may also be supported. In some examples, MIMO configurations in the DL may support up to 8 transmit antennas (with multi-layer DL transmissions of up to 8 streams) and up to 2 streams per UE. In some examples, multi-layer transmissions of up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported using up to 8 serving cells.

[0066] In some examples, access to the air interface may be scheduled. A scheduling entity (e.g., 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, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize resources allocated by the scheduling entity. A base station is not the only entity that can be used as a scheduling entity. In some examples, a UE may be used as a scheduling entity, and resources for one or more subordinate entities (e.g., one or more other UEs) may be scheduled, and other UEs may use resources scheduled by the UE for wireless communications. In some examples, a UE may act 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 a scheduling entity.

[0067] 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 relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical mesh networks, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal that is communicated from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, the sidelink signal may be communicated using a licensed spectrum (unlike wireless local area networks, which typically use an unlicensed spectrum).

[0068] exist Figure 1 In FIG. 1 , a solid line with double arrows indicates desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE on the downlink and / or uplink. A thin dashed line with double arrows indicates potentially interfering transmissions between a UE and a BS.

[0069] Figure 2 is an illustration of a method for communicating with the RAN 224 and the AS 202 (e.g., such as Figure 1 AS 150 in the communication) is in the CN 200 (for example, such as Figure 1 A block diagram of an example architecture of a CN 140 in FIG. Figure 2 As shown in FIG, the example architecture includes CN 200, RAN 224, UE 222, and data network (DN) 228 (eg, operator services, Internet access, or third party services).

[0070] CN 200 may host core network functions. CN 200 may be centrally deployed. CN 200 functionality may be offloaded (e.g., to Advanced Wireless Services (AWS)) in an effort to handle peak capacity. Figure 2 As shown in the example CN 200, the example CN 200 can 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, a NF repository function (NRF) 208, a policy control function (PCF) 210, a unified data management (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).

[0071] The AMF 218 may include the following functionality (some or all of the AMF functionality 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 encryption and integrity protection; registration management; connection management; reachability management; mobility management; lawful interception (for AMF events and interfaces to LI systems); transmission of session management (SM) messages between the UE 222 and the SMF 220; a transparent proxy for routing SM messages; access authentication; access authorization; transmission of short message service (SMS) messages between the UE 222 and the SMS function (SMSF); security anchor functionality (SEAF); security context management (SCM), which receives keys from the SEAF, which uses the keys to derive access network specific keys; location service management for regulated services; communication between the UE 222 and the location service management (LMF) and the RAN 224 Transmission of positioning service messages between LMF; EPS bearer ID allocation for interworking with Evolved Packet Service (EPS); and / or UE mobility event notification; and / or other functionality.

[0072] 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 UPF for correct traffic routing. The UPF 226 may support: packet routing and forwarding, packet inspection, quality of service (QoS) handling, external protocol data unit (PDU) session interconnection point to the DN 228, and anchor point for intra-RAT / inter-RAT mobility. The PCF 210 may support: a unified policy framework, providing 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 AF 214 may support: application influence on traffic routing, access to the NEF 206, and / or interaction with the policy framework for policy control.

[0073] Figure 3 BS 110 and UE 120 (eg, in Figure 1 For example, antenna 352, processors 366, 358, 364 and / or controller / processor 380 of UE 120 and / or antenna 334, processors 320, 330, 338 and / or controller / processor 340 of BS 110 may be used to perform the various techniques and methods described herein. Figure 3 As shown, the controller / processor 340 of the BS 110 includes a paging module 341, which can be configured to perform Figure 4-11 The operations described in one or more of and other operations described herein regarding service priority information for multi-SIM UE paging. Additionally, for example, Figure 3 As shown, the controller / processor 380 of the UE 120 also includes a paging module 381, which can be configured to perform Figure 4-11 The operations illustrated in one or more of and other operations described herein regarding service priority information for multi-SIM UE paging.

[0074] At BS 110, transmit processor 320 may receive data from data source 312 and control information from 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. Processor 320 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. 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 ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to modulators (MODs) 332a-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 up-convert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 332a-332t may be transmitted via antennas 334a-334t, respectively.

[0075] At UE 120, antennas 352a-352r may receive downlink signals from BS 110 and may provide received signals to demodulators (DEMODs) 354a-354r in the transceiver, respectively. Each demodulator 354 may condition (e.g., filter, amplify, downconvert, and digitize) a 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-354r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 120 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0076] On the uplink, at the UE 120, a transmit processor 364 may receive and process data from a data source 362 (e.g., data for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 380 (e.g., control information for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for a reference signal (e.g., 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 a demodulator 354a-354r in a transceiver (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the BS 110, the uplink signal from the UE 120 may be received by the antenna 334, processed by the modulator 332, detected by the MIMO detector 336, if applicable, and further processed by the receive processor 338 to obtain decoded data and control information sent by the UE 120. Receive processor 338 may provide decoded data to data sink 339 and decoded control information to controller / processor 340 .

[0077] Controllers / processors 340 and 380 may direct the operation at BS 110 and UE 120, respectively. Controller / processor 340 and / or other processors and modules at BS 110 may perform or direct the 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.

[0078] Example Service Priority Information for Paging of Multi-SIM User Equipment

[0079] A user equipment (UE) such as UE 120 may include more than one user identity module (SIM) and / or universal subscriber identity module (USIM). A UE having more than one SIM may be referred to as a multi-SIM device. In the present disclosure, a 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., UE service credentials). Each SIM may be configured to operate in a specific radio access technology (RAT), thereby allowing the UE to communicate using different RATs using each individual SIM.

[0080] 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.

[0081] In some cases, when communicating with the first network in dedicated mode, the UE may detect a paging in the second network, which causes the UE to suspend all operations in the first network and switch to the second network to respond to the paging, regardless of the type of information (or priority) to which the paging in the second network corresponds. For example, in some cases, even if the paging corresponds to low priority information, the UE may still switch to the second network and suspend all operations in the first network, which may involve interrupting 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, etc.

[0082] Therefore, in order to avoid the negative impact of interrupting a critical service 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), various aspects of the present disclosure provide techniques that allow a UE to decide whether to respond to a 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, which allows the UE to determine whether to establish a connection in the second network in response to the paging message.

[0083] Figure 4 is a flow diagram illustrating example operations 400 for wireless communications in accordance with certain aspects of the present disclosure. Operations 400 may be performed, for example, by a first wireless node such as a UE (eg, such as UE 120 in wireless communication network 100).

[0084] Operation 400 may be implemented as a processor on one or more processors (e.g., Figure 3 In addition, signal transmission and reception by the UE in operation 400 may be performed by one or more antennas (e.g., Figure 3 In some aspects, the transmission and / or reception of signals by the UE may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 380).

[0085] Operation 400 begins with 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). Additionally, in some cases, the second set of credentials is stored in one of the first USIM or the second USIM.

[0086] At 404, the UE receives a paging message for information transmission in the second network, wherein the paging message includes service priority information corresponding to the information transmission.

[0087] 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.

[0088] 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.

[0089] At 410, the UE takes one or more actions based at least in part on the determination.

[0090] Figure 5 5 is a flow diagram illustrating example operations 500 for wireless communication in accordance with certain aspects of the present disclosure. Operations 500 may be performed by a network entity (eg, an entity in a RAN). According to various aspects, operations 500 may be considered complementary to operations 400 performed by a UE.

[0091] Operations 500 begin, at 502, with communicating with a user equipment (UE).

[0092] At 504, the network entity determines that information needs to be transmitted to the UE.

[0093] At 506, the network entity transmits a paging message to the UE indicating that information needs to be transmitted to the UE, wherein the paging message includes service priority information corresponding to the information that needs to be transmitted to the UE.

[0094] Figure 6 6 is a flow diagram illustrating example operations 600 for wireless communication in accordance with certain aspects of the present disclosure. Operations 600 may be performed by a network entity (eg, an entity in a core network). According to various aspects, operations 600 may be considered complementary to operations 400 and 500.

[0095] Operations 600 begin, at 602, with communicating with a user equipment (UE) in a first network using a first set of UE credentials.

[0096] At 604, the network entity determines that information needs to be transmitted to the UE via the second network using a second set of UE credentials.

[0097] At 606, the network entity transmits, via the second network, a paging message 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.

[0098] Figure 7 700 is a flow diagram illustrating example operations 700 for wireless communication in accordance with certain aspects of the present disclosure. Operations 700 may be performed by a network entity, such as an entity in a core network, such as a session management function (SMF). According to various aspects, operations 700 may be considered complementary to operations 400, 500, and 600.

[0099] Operations 700 begin, at 702, by receiving a physical data unit (PDU) session establishment request with respect to a user equipment (UE).

[0100] At 704, the SMF receives policy configuration information about the PDU session from the second network entity, wherein the policy configuration information includes service priority information associated with the PDU session. In some cases, the second network entity may include a policy control function (PCF) in the core network.

[0101] At 706, the SMF determines that information needs to be transmitted to the UE.

[0102] At 708, the SMF determines service priority information corresponding to information that needs to be transmitted to the UE based on the policy configuration information.

[0103] At 710, the SMF transmits signaling for paging the UE for information that needs to be transmitted to the UE to a third network entity, wherein the signaling includes an indication of service priority information corresponding to the information that needs to be transmitted to the UE. In some cases, the third network entity may include an access and mobility management function (AMF).

[0104] As mentioned above, various aspects of the present disclosure provide techniques that allow a UE to decide whether to respond to a paging message in a second network, which in some cases includes providing service priority information within the paging message, which allows the UE to determine whether to establish a connection in the second network in response to the paging message.

[0105] For example, in some cases, the UE may use a first set of credentials to communicate with a first network (e.g., via a first RAT such as 5G). 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 communication 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 able to communicate with both the first network and the second network simultaneously (e.g., because the first RAT and the second RAT share the same Tx / Rx chain).

[0106] In some cases, while communicating with a first network, a UE may receive a paging message for information transmission in a second network (e.g., the paging message indicates that information needs to be transmitted to the UE in the second network). According to various aspects, in order to allow the UE to determine whether to respond to a paging message as described above, the paging message may include service priority information corresponding to the information transmission. 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 of 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 of 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, while all other QoS flows may be defined as non-important. In such cases, 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. Additionally, the service priority information may also include a range of different values ​​to indicate different priority levels. As explained below, the UE may act in a determined manner based on the service priority value to choose whether to respond to the paging message.

[0107] According to various 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 various 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 ​​that are each associated with a different information type or indicate different priorities associated with different information types. Accordingly, the UE may compare the service priority information included in the paging message with the set of values / different priorities from the policy configuration information to determine the service priority value corresponding to the information transmission.

[0108] 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 Radio Resource Control (RRC) message or system information in 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, 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. Additionally, in some cases, a NAS message may be received in response to a registration procedure and may include a registration acceptance message.

[0109] According to various aspects, once the priority value associated with the information transmission has been 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.

[0110] For example, in some cases, the UE may determine not to establish a connection in the second network based on the service priority value, and may ignore the paging message and continue to communicate 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 interrupting critical services in the first network as discussed above, the UE may choose to take action to ignore the paging message in the second network because the information transmission in the second network is of low priority.

[0111] In other cases, the UE may determine 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 choose to transition out of the first network (and potentially disrupt critical services in the first network) and take action to establish a connection in the second network to receive the information transmission.

[0112] Various aspects of the present disclosure will now be described in more detail regarding the signaling required to page a UE using the techniques described herein. For example, Figure 8 An example call flow for paging a UE in a current 5G system is illustrated. In some cases, the UE may be a multi-USIM device capable of communicating with a first network using a first SIM and communicating with a second network using a second SIM (or a second set of credentials for the second network stored in the first SIM), as discussed above.

[0113] According to various aspects, as illustrated, at step 0, the UE 812 may be actively communicating with the first network. At step 1a, the PCF 802 may transmit a downlink data arrival message to the UPF 804, the downlink data arrival message indicating that there is an information transmission associated with the second network for the UE 812. Thereafter, as illustrated at step 1b, the UPF 804 transmits a downlink data notification message to the SMF 806, the downlink data notification message indicating the information transmission associated with the second network for the UE 812. At step 1c, the SMF 806 determines that downlink signaling associated with the second network (e.g., including information transmission) needs to be transmitted to the UE, and at step 2, transmits a Namf_Communication_N1N2MessageTransfer message to the AMF 808 over the N11 interface. The Namf_Communication_N1N2MessageTransfer message may be a standardized message sent between the SMF 806 and the AMF 808 and is used to transparently send N1SM NAS messages from the SMF 806 to the UE 804 and N2SM messages from the SMF 806 to the RAN 810.

[0114] Thereafter, the AMF 808 may detect that the UE is in idle mode and, at step 3, send a paging message to the RAN 812. The RAN 812 may then forward the paging message to the UE at step 4, indicating that the UE is being paged by the second network. In some cases, the paging message may be sent by the RAN 810 to the UE 812 at step 4 over the Uu interface.

[0115] In the current system, the AMF 808 may send a paging message to the RAN 810, which includes only the paging ID and the registration area information associated with the second network, but no service-related information corresponding to the paging message. Figure 8 When receiving a paging message associated with the second network in step 4 of , the UE may not be aware of the service that triggered the paging, and therefore cannot make a decision whether to respond to the paging message. As discussed above, if the UE chooses to respond to the paging message, the UE may potentially interrupt key services associated with the first network.

[0116] Therefore, as mentioned above, for multi-USIM UEs, it may be advantageous to provide the UE with service priority information in a paging message (e.g., using the techniques described above) to avoid interruption of critical services in other systems (such as the first network). Since the general concept of providing service priority information within a paging message has been described above, various aspects of the present disclosure will now describe in more detail techniques for configuring service priorities in a core network and how to indicate the service priority in a paging message.

[0117] Fig. 9 An example call flow for configuring service priorities in a core network 902 in accordance with certain aspects presented herein is illustrated. As illustrated, service priorities in the core network 902 may be configured during a packet data unit (PDU) setup / modification procedure / QoS setup procedure initiated by a UE 904. For example, as illustrated, at step 1, the UE 904 may transmit 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 various aspects, the UE may also be using a first set of credentials to communicate in a first network, as described above.

[0118] In step 2, in response to receiving the PDU session establishment request, the AMF 906 may transmit a Nsmf_PDUSession_CreateSMContext request to the SMF 908. The Nsmf_PDUSession_CreateSMContext request may be a standardized message for establishing a new PDU session.

[0119] In step 3, during the PDU session establishment procedure, the SMF 908 may interact with the PCF 912 to obtain policy configuration information about 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, during the PDU session modification procedure, if a new QoS rule is assigned to the PDU session, the service priority for the newly assigned QoS flow may be included in the policy and charging control (PCC) rule sent from the PCF 912 to the SMF 908.

[0120] In step 4, after receiving the policy configuration information from PCF 912, SMF 908 may send an N4 session establishment / modification procedure message, which may include QoS rules for QoS flows, to UPF 910. Additionally, in some cases, the N4 session establishment / modification procedure message sent to UPF 910 may optionally include a service priority for the QoS flow.

[0121] Thereafter, as illustrated in step 5, the SMF 908 may transmit a PDU session establishment response message to the UE 904. The PDU session establishment response message may include policy configuration information regarding the PDU session initiated by the UE. As mentioned, the policy configuration information may include a service priority for a QoS flow and a service priority for downlink signaling for the data network name / slice requested in the PDU session establishment request.

[0122] According to aspects, once service priority has been configured in the core network 902, the service priority configuration can be used when transmitting a paging message to the UE 904. The technique for transmitting a paging message to a UE can depend on whether the UE is in idle mode or in RRC inactive mode, as explained below.

[0123] Fig.10 An example call flow for transmitting a paging message to a UE in idle mode according to certain aspects presented herein is illustrated. As illustrated, Fig.10 Steps 1 and 2 can be done with Fig. 9 Steps 1-3 are the same as in , where UE 1004 initiates a PDU session establishment / QoS establishment procedure in the second network, and SMF 1008 retrieves service priority (e.g., policy configuration information) from PCF 1012.

[0124] After the PDU session / QoS flow has been established, UE 1004 may enter idle mode in step 3.

[0125] In step 4a, downlink data associated with the second network may arrive at UPF 1010.

[0126] According to various aspects, at step 4b, if the SMF 1008 did not send the service priority to the UPF 1010 during the PDU session establishment procedure (e.g., in the N4 message discussed above), the UPF 1010 may transmit a downlink data notification including the QoS flow information to the SMF 1008. According to various aspects, based on the downlink data notification message, the SMF 1008 may determine that information needs to be transmitted to the UE 1004. The SMF 1008 may then determine (e.g., based on the policy configuration information received from the PCF 1012) the service priority for the QoS flow identified in the QoS flow information in the downlink data notification.

[0127] According to various aspects, if the SMF 1008 does send a service priority to the UPF 1010 (e.g., in the N4 message discussed above), the UPF 1010 determines the service priority for the QoS flow based on 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.

[0128] Additionally, in some cases, the SMF 1008 may determine that downlink signaling needs to be transmitted to the UE 1004. In this case, the SMF determines the service priority for the DL signaling according to the policy configuration information received from the PCF 1012 in step 4c.

[0129] Thereafter, the SMF 1008 may transmit to the AMF 1006 signaling for paging the UE 1004 for the information that needs to be transmitted to the UE 1004. In some cases, the signaling may include an indication of service priority information corresponding to the information that needs to be transmitted to the UE 1004. For example, as illustrated in step 5, the SMF 1008 may send a Namf_Communication_N1N2MessageTransfer message to the AMF 1006 over the N11 interface and include the determined service priority associated with the information that needs to be transmitted to the UE 1004.

[0130] According to various aspects, if the UE is in idle mode and the AMF 1006 decides to transmit a paging message to the UE, then in step 6, the AMF 1006 may transmit a paging message including a service priority associated with information that needs to be transmitted to the UE 1004 to the RAN 1014 (e.g., a second network).

[0131] Thereafter, at step 7, the RAN 1014 may transmit a paging message with service priority information over the Uu interface to the UE 1004. In general, the RAN 1014 may communicate with the UE 1004, determine that information needs to be transmitted to the UE 1004 (e.g., in response to receiving a paging message from the AMF 1006), and may transmit a paging message to the UE 1004 indicating that the information needs to be transmitted to the UE 1004. As mentioned, the paging message may include service priority information corresponding to the information that needs to be transmitted to the UE 1004.

[0132] According to various aspects, for example, 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 to completely ignore the paging message, as described above. For example, as mentioned, if the paging message includes service priority information corresponding 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.

[0133] Fig.11 An example call flow for transmitting a paging message to a UE in RRC inactive mode according to certain aspects presented herein is illustrated. As illustrated, Fig.11 Steps 1-3 can be done with Fig. 9 Steps 1-3 are the same as in , where UE 1104 initiates a PDU session establishment / QoS establishment procedure in the second network, and SMF 1108 retrieves service priority (e.g., policy configuration information) from PCF 1112.

[0134] exist Fig.11 In step 4 of , during the PDU session establishment procedure, SMF 1108 may send a Nsmf_PDUSession_CreateSMContext response message to AMF 1106. The service priority and DL signaling service priority information about the QoS flow received from PCF 1112 may be included in the N2 SM container of the Nsmf_PDUSession_CreateSMContext response message.

[0135] At step 5, the AMF 1106 may forward the N2 SM container to the RAN 1114 (eg, a second network). According to various aspects, the RAN 1114 may store the service priority information received in the N2 SM container as the SM context of the UE 1104.

[0136] At step 6, the RAN 1114 establishes a data radio bearer (DRB) for the PDU session according to standard procedures (e.g., as indicated in the RRC reconfiguration information in some cases). 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 the PDU session, which may be used to transmit data over the radio interface.

[0137] In some cases, a new QoS rule may be assigned to a PDU session in a PDU session modification procedure. In this case, service priority information about the new QoS flow may be sent from the PCF 1112. The SMF 1108 may also include the service priority information about 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 of the UE 1104.

[0138] At step 7, UE 1114 may enter RRC inactive mode.

[0139] According to various aspects, 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 delivers the information to the RAN 1114 (e.g., the second network) at step 8. The RAN 1114 may then determine the service priority for the QoS flow associated with the information that needs to be transmitted to the UE 1104 based on the service priority information stored as the SM context of the UE 1104. Thereafter, at 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.

[0140] According to various aspects, for example, 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 to completely ignore the paging message, as described above. For example, as mentioned, if the paging message includes service priority information corresponding 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.
