Description

Technical Field

[0001] The technologies discussed below generally relate to wireless communication systems, and in particular to paging multiple subscriber devices during a shared paging period.

[0002] introduction

[0003] User equipment (UE) often uses subscriptions to connect to a serving network that provides one or more services, such as voice calling or data services. For example, the subscription used by the UE may be associated with a subscription module or device, such as a Subscriber Identity Module (SIM) to which the UE accesses to use the subscription. With the development of subscription-based services, there is increasing use of UEs capable of using two or more subscriptions. In one example, a UE may implement dual SIMs, allowing the UE to connect to the serving network using two different subscriptions provided by two separate SIMs. After completing the network registration procedure with the core network, the core network can page one or more SIMs. Various improvements to page one or more devices using multiple subscriptions are being investigated.

[0004] A brief overview of some examples

[0005] The following provides a brief overview of one or more aspects of this disclosure to provide a basic understanding of these aspects. This overview is not an exhaustive summary of all conceived features of this disclosure, and is neither intended to identify key or defining elements of all aspects of this disclosure nor to define the scope of any or all aspects of this disclosure. Its sole purpose is to present some concepts of one or more aspects of this disclosure in a simplified form as a prelude to the more detailed description that follows.

[0006] Various aspects of this disclosure relate to pageing multiple devices during a shared paging period.

[0055] Detailed description

[0056] The detailed description that follows, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent only the configurations in which the concepts described herein can be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0057] While aspects and embodiments are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, embodiments and / or devices may arise via integrated chip embodiments and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / shopping devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to particular use cases or applications, broad applicability of the described innovations is possible. Implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or OEM devices or systems incorporating one or more aspects of the described innovations. In some practical contexts, devices incorporating the described aspects and features may also necessarily include additional components and features for implementing and practicing the claimed and described embodiments. For example, the transmission and reception of wireless signals requires several components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The innovations described herein are intended to be implemented in a wide variety of devices, chip-level components, systems, distributed deployments, end-user devices, etc., of various sizes, shapes, and configurations.

[0058] Multiple devices can be provided to communicate with the base station using multiple subscriptions. For example, the UE can implement multiple subscription identification modules (SIMs) that can be used separately to communicate using multiple subscriptions. Multiple devices can be paged by the base station during separate paging times. Therefore, if the UE and / or multiple devices are in power-saving mode, the UE and / or the multiple devices may need to wake up multiple times during the separate paging times used for those multiple devices. However, waking up multiple times within these separate paging times may not be desirable for power saving.

[0059] According to one aspect of this disclosure, multiple devices can be paged during a shared paging timing. Thus, for example, the UE and / or the multiple devices can wake up once during the paging timing to receive one or more paging messages for the multiple devices, rather than waking up multiple times during separate paging timings for the multiple devices. To achieve this, a paging reference identifier is assigned and associated with the multiple devices such that the paging reference identifier can be used to determine the paging timing.

[0060] The various concepts presented throughout this disclosure can be implemented across a wide range of telecommunications systems, network architectures, and communication standards. Now refer to... Figure 1The various aspects of this disclosure are explained with reference to a wireless communication system 100, by way of illustrative example and not limitation. The wireless communication system 100 includes three interaction domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. The wireless communication system 100 enables the UE 106 to perform data communication with an external data network 110 (such as, but not limited to, the Internet).

[0061] RAN 104 can implement any suitable one or more wireless communication technologies to provide radio access to UE 106. As an example, RAN 104 can operate according to the 3rd Generation Partnership Project (3GPP) New Radio (NR) specification (commonly referred to as 5G). As another example, RAN 104 can operate in a hybrid of 5G NR and the Evolved Universal Terrestrial Radio Access Network (eUTRAN) standard (commonly referred to as LTE). 3GPP refers to this hybrid RAN as Next Generation RAN, or NG-RAN. Of course, many other examples can be utilized within the scope of this disclosure.

[0062] As explained, RAN 104 includes multiple base stations 108. Broadly speaking, a base station is a network element in a radio access network responsible for radio transmissions to and from a UE in one or more cells. In different technologies, standards, or contexts, a base station may be referred to by those skilled in the art as a base transceiver station (BTS), radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), access point (AP), B-node (NB), evolved B-node (eNB), next-generation B-node (gNB), or some other suitable term.

[0063] Radio access network 104 is further described as supporting wireless communication for multiple mobile devices. In 3GPP standards, a mobile device may be referred to as User Equipment (UE), but may also be referred to by those skilled in the art as a mobile station (MS), subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, radio terminal, remote terminal, handheld device, terminal, user agent, mobile client, client, or any other suitable term. A UE may be a device (e.g., a mobile device) that provides users with access to network services.

[0064] In this document, a “mobile” device does not necessarily need to be mobile and may be stationary. The term mobile device or mobile equipment refers to a wide variety of devices and technologies. A UE may include several hardware structural components that are sized, shaped, and arranged to facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc., electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile devices, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal computers (PCs), laptops, netbooks, smartbooks, tablets, personal digital assistants (PDAs), and a wide variety of embedded systems, such as those corresponding to the “Internet of Things” (IoT). Additionally, mobile devices can be automobiles or other transportation vehicles, remote sensors or actuators, robots or robotic equipment, satellite radios, Global Positioning System (GPS) devices, object tracking devices, drones, multi-rotor aircraft, quadcopters, remote control devices, consumer and / or wearable devices (such as glasses), wearable cameras, virtual reality devices, smartwatches, health or fitness trackers, digital audio players (e.g., MP3 players), cameras, game consoles, etc. Mobile devices can also be digital home or smart home devices, such as home audio, video and / or multimedia equipment, appliances, vending machines, smart lighting equipment, home security systems, smart meters, etc. Mobile devices can also be smart energy devices, security devices, solar panels or solar arrays, municipal infrastructure equipment controlling electricity, lighting, water, etc. (e.g., smart grids); industrial automation and enterprise equipment; logistics controllers; agricultural equipment; military defense equipment, vehicles, aircraft, ships, and weapons, etc. Furthermore, mobile devices can provide connected or telemedicine support, such as remote healthcare. Remote healthcare devices may include remote healthcare monitoring devices and remote healthcare supervision devices, whose communications may be given priority or preferential access over other types of information, for example, in the form of priority access for critical service data transmission and / or relevant QoS for critical service data transmission.

[0065] Wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions over the air interface from a base station (e.g., base station 108) to one or more UEs (e.g., UE 106) can be referred to as downlink (DL) transmissions. According to certain aspects of this disclosure, the term downlink can refer to point-to-multipoint transmissions originating at a scheduling entity (further described below; e.g., base station 108). Another way to describe this scheme is to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. According to a further aspect of this disclosure, the term uplink can refer to point-to-point transmissions originating at a scheduled entity (further described below; e.g., UE 106).

[0066] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., base station 108) allocates resources for communication among some or all of the equipment and devices within its service area or cell. Within this disclosure, as further discussed below, the scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities. That is, for scheduled communication, UE 106 (which may be a scheduled entity) may utilize resources allocated by scheduling entity 108.

[0067] Base station 108 is not the only entity that can be used as a scheduling entity. That is, in some examples, a UE can be used as a scheduling entity to schedule resources for one or more scheduled entities (e.g., one or more other UEs).

[0068] like Figure 1 As explained, scheduling entity 108 may broadcast downlink traffic 112 to one or more scheduled entities 106. Broadly speaking, scheduling entity 108 is a node or device responsible for scheduling traffic (including downlink traffic 112 and, in some examples, uplink traffic 116 from one or more scheduled entities 106 to scheduling entity 108) in a wireless communication network. On the other hand, scheduled entity 106 is a node or device that receives downlink control information 114 (including, but not limited to, scheduling information (e.g., permission), synchronization or timing information), or other control information from another entity in the wireless communication network (such as scheduling entity 108).

[0069] Generally, base station 108 may include a backhaul interface for communicating with the backhaul section 120 of a wireless communication system. Backhaul 120 provides a link between base station 108 and core network 102. Furthermore, in some examples, the backhaul network provides interconnection between the respective base stations 108. Various types of backhaul interfaces can be employed, such as a direct physical connection using any suitable transport network, a virtual network, etc.

[0070] Core network 102 may be part of wireless communication system 100 and may be independent of the radio access technology used in RAN 104. In some examples, core network 102 may be configured according to 5G standards (e.g., 5GC). In other examples, core network 102 may be configured according to 4G evolved packet core (EPC) or any other suitable standard or configuration.

[0071] Now refer to Figure 2 The block diagrams provided are examples of various components illustrating a 5G wireless communication system (5GS) 200, provided by way of example and not limitation. In some examples, the 5GS 200 may be as described above and in... Figure 1 The same wireless communication system 100 described herein. 5GS 200 includes User Equipment (UE) 202, NR RAN 204, and core network 206. The wireless communication system 200 enables UE 202 to perform data communication with external data networks 214, such as (but not limited to) the Internet, Ethernet networks, IP Multimedia Subsystem (IMS) networks, or local area networks.

[0072] For example, core network 206 may include Access and Mobility Management Function (AMF) 208, Session Management Function (SMF) 210, and User Plane Function (UPF) 212. AMF 208 and SMF 210 employ control plane (e.g., Non-Access Stratum (NAS)) signaling to perform various functions related to mobility management and session management for UE 202. For example, AMF 208 provides connectivity, mobility management, and authentication for UE 202, while SMF 210 provides session management for UE 202 (e.g., processing signaling related to Protocol Data Unit (PDU) sessions between UE 202 and external DN 214). UPF 212 provides user plane connectivity to route 5G (NR) packets to / from UE 202 via NR RAN 204.

[0073] Core network 206 may further include other functions such as Policy Control Function (PCF) 216, Authentication Server Function (AUSF) 218, Unified Data Management (UDM) 220, Network Slice Selection Function (NSSF) 222, and other functions (not explained for simplicity). PCF 216 provides policy information (e.g., rules) for control plane functions such as network slicing, roaming, and mobility management. Additionally, PCF 216 supports 5G Quality of Service (QoS) policies, network slicing policies, and other types of policies. AUSF 218 performs authentication for UE 202. UDM 220 facilitates the generation of authentication and key negotiation (AKA) credentials, performs user identification, and manages subscription information and UE context. In some examples, AMF 208 includes a Security Anchor in Coexistence (SEAF) function, which allows UE 202 to be re-authenticated when moving between different NR RANs 204 without having to perform the full authentication process with AUSF 218. NSSF 222 redirects traffic to network slices. For example, network slices can be defined for different categories of subscribers or use cases, such as smart homes, the Internet of Things (IoT), connected cars, smart energy grids, etc. Each use case can receive a unique set of optimized resources and network topologies (e.g., network slices) to meet the connectivity, speed, power, and capacity requirements of the use case.

[0074] To establish a connection to the 5G core network 206 via NR RAN 204, UE 202 can transmit registration requests and PDU session establishment requests to the 5G core network 206 via NR RAN 204. AMF 208 and SMF 210 can process the registration requests and PDU session establishment requests and establish a PDU session between UE 202 and external DN 214 via UPF 212. A PDU session may include one or more sessions (e.g., a data session or a data stream) and may be served by multiple UPF 212s (only one is shown for convenience). Examples of data streams include, but are not limited to, IP streams, Ethernet streams, and unstructured data streams.

[0075] Now refer to Figure 3 The RAN 300 is provided as an example, not a limitation. In some examples, the RAN 300 may be used in conjunction with those described above and in... Figure 1 The RAN 104 and / or the above-described and in Figure 2 The same applies to NR RAN 204 as explained in the document. The geographical area covered by RAN 300 can be divided into cellular areas (cells) that can be uniquely identified by the user equipment (UE) based on an identifier broadcast from an access point or base station. Figure 3Macrocells 302, 304, and 306, and small cell 308, are described, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same base station. Radio links within a sector may be identified by a single logical identifier belonging to that sector. In a cell divided into sectors, multiple sectors within the cell may be formed by an antenna array, where each antenna is responsible for communication with UEs in a portion of the cell.

[0076] exist Figure 3 In the illustration, two base stations 310 and 312 are shown in cells 302 and 304; and a third base station 314 is shown as a remote radio head (RRH) 316 controlling cell 306. That is, the base stations may have integrated antennas, or may be connected to the antenna or RRH via feed cables. In the illustrated example, cells 302, 304, and 316 may be referred to as macrocells because base stations 310, 312, and 314 support cells with large sizes. Furthermore, base station 318 is shown in a small cell 308 (e.g., microcell, picocell, femtocell, home base station, home B-node, home evolved B-node, etc.), which may overlap with one or more macrocells. In this example, cell 308 may be referred to as a small cell because base station 318 supports cells with relatively small sizes. Cell size settings can be determined based on system design and component constraints.

[0077] It will be understood that the radio access network 300 may include any number of radio base stations and cells. Furthermore, relay nodes may be deployed to extend the size or coverage area of ​​a given cell. Base stations 310, 312, 314, and 318 provide radio access points to the core network for any number of mobile devices. In some examples, base stations 310, 312, 314, and / or 318 may be connected to the network described above and in… Figure 1 The base station / scheduling entity 108 described in the Chinese explanation is the same.

[0078] Figure 3 Further includes a quadcopter or drone 320, which can be configured to serve as a base station. That is, in some examples, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station (such as the quadcopter 320).

[0079] Within RAN 300, a cell may include UEs capable of communicating with one or more sectors of each cell. Furthermore, each base station 310, 312, 314, 318, and 320 may be configured to provide all UEs in the respective cell to the core network 102 (see [link to core network 102]). Figure 1Access points. For example, UEs 322 and 324 may communicate with base station 310; UEs 326 and 328 may communicate with base station 312; UEs 330 and 332 may communicate with base station 314 via RRH 316; UE 334 may communicate with base station 318; and UE 336 may communicate with mobile base station 320. In some examples, UEs 322, 324, 326, 328, 330, 332, 334, 336, 338, 340, and / or 342 may communicate with the access points described above and in... Figure 1 The UE / scheduled entity 106 described in the text is the same.

[0080] In some examples, a mobile network node (e.g., a quadcopter 320) can be configured to act as a UE. For example, the quadcopter 320 can operate within a cell 302 by communicating with a base station 310.

[0081] In a further aspect of RAN 300, sidelink signals can be used between UEs without relying on scheduling or control information from a base station. For example, two or more UEs (e.g., UEs 326 and 328) can communicate with each other using peer-to-peer (P2P) or sidelink signal 327 without relaying the communication through a base station (e.g., base station 312). In a further example, UE 338 is described as communicating with UEs 340 and 342. Here, UE 338 can act as a scheduling entity or a primary sidelink device, and UEs 340 and 342 can act as scheduled entities or non-primary (e.g., secondary) sidelink devices. In yet another example, the UE can act as a scheduling entity in a device-to-device (D2D), peer-to-peer (P2P), or vehicle-to-vehicle (V2V) network, and / or a mesh network. In a mesh network example, UEs 340 and 342 can optionally communicate directly with each other in addition to communicating with scheduling entity 338. Thus, in a wireless communication system with scheduled access to time-frequency resources and with cellular, P2P, or mesh configurations, a scheduling entity and one or more scheduled entities can communicate using the scheduled resources.

[0082] In the radio access network 300, the ability of a UE to communicate independently of its location while on the move is referred to as mobility. The various physical channels between the UE and the radio access network are generally defined within the Access and Mobility Management Function (AMF, not explained). Figure 1 The AMF is established, maintained, and released under the control of the core network 102 (part of the core network). The AMF may include the Security Context Management Function (SCMF) for managing the security contexts of both the control plane and user plane functionalities, and the Security Anchor Function (SEAF) for performing authentication.

[0083] In various aspects of this disclosure, the radio access network 300 may utilize DL-based mobility or UL-based mobility to achieve mobility and handover (i.e., the UE's connection is transferred from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity, or at any other time, the UE may monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Depending on the quality of these parameters, the UE may maintain communication with one or more neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE may perform a handover or handover from the serving cell to a neighboring (target) cell. For example, UE 324 (described as a means of transportation, but any suitable form of UE may be used) may move from a geographic area corresponding to its serving cell 302 to a geographic area corresponding to a neighboring cell 306. When the signal strength or quality from neighboring cell 306 exceeds that of its serving cell 302 for a given amount of time, UE 324 may transmit a report message indicating this condition to its serving base station 310. In response, UE 324 may receive a handover command, and the UE may undergo a handover to cell 306.

[0084] In a network configured for UL-based mobility, UL reference signals from each UE can be used by the network to select a serving cell for each UE. In some examples, base stations 310, 312, and 314 / 216 can broadcast unified synchronization signals (e.g., unified primary synchronization signal (PSS), unified secondary synchronization signal (SSS), and unified physical broadcast channel (PBCH)). UEs 322, 324, 326, 328, 330, and 332 can receive unified synchronization signals, derive carrier frequencies and time slot timings from these synchronization signals, and transmit uplink pilots or reference signals in response to the derived timings. The uplink pilot signal transmitted by a UE (e.g., UE 324) can be received concurrently by two or more cells (e.g., base stations 310 and 314 / 216) within the radio access network 300. Each of these cells can measure the strength of the pilot signal, and the radio access network (e.g., one or more of base stations 310 and 314 / 216 and / or a central node within the core network) can determine the serving cell for UE 324. As UE 324 moves within the radio access network 300, the network can continue to monitor the uplink pilot signal transmitted by UE 324. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds the signal strength or quality measured by the serving cell, the network 300 can, with or without notification, switch UE 324 from the serving cell to the neighboring cell.

[0085] Although the synchronization signal transmitted by base stations 310, 312, and 314 / 216 can be uniform, it does not necessarily identify a specific cell. Instead, it can identify a zoning that includes multiple cells operating on the same frequency and / or having the same timing. Using zoning in 5G networks or other next-generation communication networks enables uplink-based mobility frameworks and improves the efficiency of both the UE and the network because the number of mobility messages that need to be exchanged between the UE and the network can be reduced.

[0086] The air interface in the radio access network 300 can utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link where both endpoints can communicate with each other in both directions. Full-duplex means that both endpoints can communicate with each other simultaneously. Half-duplex means that only one endpoint can send information to the other endpoint at a time. In a wireless link, a full-duplex channel generally relies on the physical isolation between the transmitter and receiver, and appropriate interference cancellation techniques. Full-duplex simulation for wireless links is typically achieved using Frequency Division Duplex (FDD) or Time Division Duplex (TDD). In FDD, transmissions in different directions operate at different carrier frequencies. In TDD, transmissions in different directions on a given channel are separated using time division multiplexing. That is, at some times, the channel is dedicated to transmissions in one direction, and at other times, the channel is dedicated to transmissions in the other direction, where the direction can change very rapidly, for example, several times per time slot.

[0087] In some aspects of this disclosure, the scheduling entity and / or the scheduled entity can be configured for beamforming and / or multiple-input multiple-output (MIMO) techniques. Figure 4 An example of a MIMO-enabled wireless communication system 400 has been described. In the MIMO system, transmitter 402 includes multiple transmit antennas 404 (e.g., N transmit antennas), and receiver 406 includes multiple receive antennas 408 (e.g., M receive antennas). Thus, there are N×M signal paths 408 from the transmit antennas 404 to the receive antennas 410. Each of transmitter 402 and receiver 406 may be implemented, for example, in scheduling entity 108, scheduled entity 106, or any other suitable wireless communication device.

[0088] The use of such multi-antenna techniques enables wireless communication systems to utilize the spatial domain to support spatial multiplexing, beamforming, and transmit diversity. Spatial multiplexing can be used to simultaneously transmit different data streams (also known as layers) on the same time-frequency resources. These data streams can be transmitted to a single UE to increase the data rate or to multiple UEs to increase the overall system capacity, the latter being known as multi-user MIMO (MU-MIMO). This is achieved by spatially precoding each data stream (i.e., multiplying these data streams by different weights and phase shifts) and then transmitting each spatially precoded stream over multiple transmit antennas on the downlink. The spatially precoded data streams arrive at the UE with different spatial signatures, which allow each UE to recover one or more data streams intended for that UE. On the uplink, each UE transmits spatially precoded data streams, which allows the base station to identify the source of each spatially precoded data stream.

[0089] The number of data streams or layers corresponds to the transmission rank. Generally, the rank of a MIMO system 400 is limited by the lower of the number of transmit or receive antennas 404 or 408. Additionally, channel conditions at the UE and other considerations (such as available resources at the base station) can also affect the transmission rank. For example, the rank assigned to a particular UE on the downlink (and therefore the number of data streams) can be determined based on a rank indicator (RI) transmitted from that UE to the base station. The RI can be determined based on the antenna configuration (e.g., the number of transmit and receive antennas) and the measured signal-to-interference-plus-noise ratio (SINR) on each receive antenna. The RI can indicate, for example, the number of layers that can be supported under the current channel conditions. The base station can use the RI along with resource information (e.g., available resources and the amount of data to be scheduled for the UE) to assign a transmission rank to the UE.

[0090] In a Time Division Duplex (TDD) system, UL and DL are reciprocal, with each using different time slots of the same frequency bandwidth. Therefore, in a TDD system, the base station can assign a rank for DL ​​MIMO transmission based on UL SINR measurements (e.g., based on a probe reference signal (SRS) or other pilot signal transmitted from the UE). Based on the assigned rank, the base station can then transmit a CSI-RS using a separate C-RS sequence for each layer to provide multi-layer channel estimation. According to this CSI-RS, the UE can measure the channel quality across layers and resource blocks and feed back CQI and RI values ​​to the base station for use when updating the rank and assigning REs for future downlink transmissions.

[0091] In the simplest case, such as Figure 4 As shown, rank-2 spatial multiplexing transmission on a 2x2 MIMO antenna configuration will transmit one data stream from each transmit antenna 404. Each data stream arrives at each receive antenna 408 along a different signal path 410. Receiver 406 can then reconstruct these data streams using the signals received from each receive antenna 408.

[0092] A UE can communicate with a network using subscriptions to services provided by the network (e.g., data services, voice services). The UE can implement a subscription module (such as a Subscriber Identity Module (SIM)) to connect to the network. In some cases, the SIM may be a UMTS SIM (USIM). The UE can be configured to communicate using two or more subscriptions. For example, a UE implementing multiple SIMs associated with multiple subscriptions can communicate using multiple subscriptions via multiple SIMs. Multiple SIMs can be separate radio devices capable of operating independently of each other. For example, multiple SIMs can have independent connections to a RAN (e.g., a base station) for Layer 1, Layer 2, and Layer 3 connectivity. The UE can use multiple subscriptions to establish communication links to perform communication using multiple subscriptions. Communication links can be established with a shared base station. For example, for a UE with two SIMs and dual SIM, dual active (DSDA) capability, both SIMs can remain connected (or active) to the network simultaneously and can thus be used to perform communication simultaneously. In another example, for a UE with two SIMs and dual SIM, dual standby (DSDS) capability, when one SIM is used to actively perform communication, the other SIM is in standby mode. In another example, multiple devices, each with its own SIM and operating independently, can also communicate with the network.

[0093] Multiple SIMs can originate from the same operator or from different operators. In cases where multiple SIMs belong to the same or equivalent operator, improvements can be made to coordinate links used by the multiple SIMs. For example, if the base station is aware that multiple connections originate from the same UE (e.g., thus sharing the same Media Access Control (MAC) layer and / or the same physical layer), improvements can be made to the base station to optimize operation on multiple links.

[0094] One area of ​​optimization might relate to paging for multiple subscriptions by the core network. A UE, possibly in power-saving mode, can wake up to monitor paging times to receive paging messages from the core network. Generally, when multiple subscriptions / SIMs are registered with the core network, these subscriptions / SIMs can use different paging times. For example, if the first SIM and the second SIM in the UE are registered with the core network, the UE can wake up during the first paging time to monitor paging messages for the first SIM and during the second paging time, which is different from the first paging time. Therefore, using multiple subscriptions / SIMs may require the UE to wake up multiple times to monitor paging for each subscription / SIM separately. Since the UE may need to wake up more frequently for more subscriptions / SIMs, more power may be consumed as more subscriptions / SIMs are used and registered with the core network, which may not be desirable for power-saving purposes.

[0095] The UE can register with the core network via the AMF. When the UE registers with the AMF in the core network, the AMF assigns a 5G Globally Unique Temporary Identifier (GUTI) to the UE. During the paging procedure, the AMF may send a paging request to the RAN, which may include the Serving Temporary Mobile Subscriber Identity (S-TMSI) corresponding to the UE, where the S-TMSI may be the last 10 bits of the 5G GUTI. Subsequently, the RAN can use the S-TMSI to determine the paging timing and paging frame. The 5G-S-TMSI may also be included in the paging message transmitted by the RAN to identify the UE. However, if the S-TMSI is used to determine the paging timing, multiple paging timings can be determined for multiple subscriptions / SIMs associated with multiple S-TMSIs respectively. Furthermore, the 5G GUTI is a temporary identifier that may change continuously, so the S-TMSI or any other identifier based on the 5G GUTI may also change continuously, which is undesirable. Therefore, using the 5G GUTI or S-TMSI to determine the paging timing and / or paging frame may be undesirable.

[0096] According to one aspect of this disclosure, a base station can transmit one or more paging messages for multiple subscriptions during a shared paging time, rather than utilizing multiple paging times for multiple subscriptions. In another aspect, a paging reference identifier can be assigned and associated with multiple subscriptions such that the same paging time for paging multiple subscriptions can be determined based on the paging reference identifier. Because a single paging time is used to paging multiple subscriptions, the UE may need to wake up only once to monitor paging for multiple subscriptions during that paging time, rather than waking up multiple times for multiple subscriptions.

[0097] Figure 5 This is an example diagram 500 illustrating communication between multiple subscription modules / devices, base stations, and the core network according to one aspect of this disclosure. Figure 5 In one aspect, multiple devices may be implemented in UE 502, wherein the multiple devices may include a first device 504 associated with a first subscription and a second device 506 associated with a second subscription. In one aspect, the first device 504 may be a first SIM, and the second device 506 may be a second SIM. UE 502 may be as follows: Figure 1 , 2 The scheduled entity or base station explained in any one or more of 3 and / or 4. For interpretive purposes, in Figure 5The diagram illustrates and explains a dual-device scenario with a first device 504 and a second device 506. However, it will be understood that this disclosure is not limited to a UE with two devices, and more than two devices for more than two subscriptions can also be used. Furthermore, in one aspect, these multiple devices can be separate wireless devices capable of independent operation and can be implemented in different UEs. The first device 504 and the second device 506 can communicate with the base station 512 via a corresponding connection to the base station 512. The base station 512 can be as shown in... Figure 1 , 2 The scheduling entity or base station described in any one or more of 3 and / or 4. Base station 512 can also communicate with core network equipment 522, including the first AMF 524 and the second AMF 526. Although Figure 5 The illustration shows a first AMF 524 and a second AMF 526 implemented within core network device 522; however, another implementation, where the first AMF 524 and the second AMF 526 are implemented in two separate core networks, is also possible. In one aspect, the first AMF 524 may communicate with a first device 504, and the second AMF 526 may communicate with a second device 506. Core network device 522 may be... Figure 1 The core network explained in either or both of the above.

[0098] A first device 504 (e.g., UE 502) may be used to perform a first network registration with core network device 522 using a first subscription (e.g., via a first AMF 524). During the first network registration, a paging reference identifier may be associated with the first subscription and / or the first device 504. According to a first approach, the first device 504 may perform a first network registration with core network device 522 by transmitting a first registration request for first network registration to core network device 522 using a first subscription (e.g., via a first AMF 524), wherein the first registration request may include a paging reference identifier request to enable core network device 522 (e.g., via a first AMF 524) to assign a paging reference identifier to associate that paging reference identifier with the first subscription and / or the first device 504. Subsequently, during the first network registration, core network device 522 (e.g., via a first AMF 524) may transmit a first registration response including the paging reference identifier to the first device 504 in response to the first registration request. The first registration response can be received by the first device 504 using the first subscription. The first device 504 can retrieve the paging identifier from the first registration response and transmit the paging reference identifier to the second device 506.

[0099] According to the second method, the first device 504 may perform a first network registration with the core network device 522 by: assigning a paging reference identifier to associate the paging reference identifier with a first subscription and / or the first device 504, and transmitting a first registration request for the first network registration to the core network device 522 using the first subscription (e.g., via the first AMF 524), wherein the first registration request includes the paging reference identifier associated with the first subscription and / or the first device 504. The first device 504 may convey the paging reference identifier to the second device 506. Subsequently, during the second network registration, the core network device 522 (e.g., via the first AMF 524) may transmit a first registration response to the first device 504 in response to the first registration request. In one aspect, the first registration response in the second method may not include the paging reference identifier associated with the first subscription and / or the first device 504. The first registration response may be received by the first device 504 using the first subscription.

[0100] Therefore, for example, after completing the first network registration, the paging reference identifier may be associated with the first subscription and / or the first device 504. In one aspect, upon receiving the first registration request, the core network device 522 (e.g., via the first AMF 524) may also assign a first GUTI (e.g., a first 5G GUTI) associated with the first device 504. In another aspect, the first registration response may further include the first GUTI associated with the first device 504. In another aspect, the paging reference identifier may be assigned independently of the first GUTI. In another aspect, the paging reference identifier may be randomly generated and may include 10 bits or any number of bits.

[0101] The second device 506 can be used to perform a first network registration with the core network device 522 using a second subscription (e.g., via a second AMF 526). During the second network registration, a paging reference identifier can be further associated with the second subscription. Therefore, after performing both the first and second network registrations, the paging reference identifier can be associated with both the first and second subscriptions. In other words, after multiple subscriptions / SIMs perform network registration with the core network, the paging reference can be associated with and thus can be used for multiple subscriptions. Figure 5In this configuration, the second device 506 can perform second network registration with the core network device 522 by sending a second registration request for second network registration to the core network device 522 using a second subscription (e.g., via the second AMF 526). The second registration request may include a paging reference identifier, which the core network device 522 (e.g., via the second AMF 526) can further associate with the second subscription and / or the second device 506. Thus, after the second network registration, the paging reference identifier is associated with the first subscription and / or the first device 504 and the second subscription and / or the second device 506. Subsequently, during the second network registration, the core network device 522 (e.g., via the second AMF 526) can send a second registration response to the second device 506 in response to the second registration request. The second registration response can be received by the second device 506 using the second subscription.

[0102] In one aspect, upon receiving a second registration request, core network device 522 (e.g., via second AMF 526) may also assign a second GUTI (e.g., a second 5G GUTI) associated with second device 506. In another aspect, the second registration response may further include the second GUTI associated with second device 506.

[0103] After performing the first network registration and the second network registration, core network device 522 may request base station 512 to page the first device 504 and the second device 506, so that base station 512 may page the first device 504 and the second device 506 during a paging timing determined based on a paging reference identifier. For example, base station 512 may be requested to page the first device 504 and the second device 506 at any time after the completion of the first network registration and the second network registration. At this time, the paging reference identifier used to determine the paging timing is associated with the first subscription and / or the first device 504 and the second subscription and / or the second device 506. In one aspect, core network device 522 (e.g., via the first AMF 524 and / or the second AMF 526) may request base station 512 to transmit one or more paging messages to the first device 504 and the second device 506 during the paging timing based on the paging reference identifier. Specifically, core network device 522 (e.g., via first AMF 524) may transmit a first paging request to base station 512, wherein the first paging request includes the paging reference identifier and a first device identifier associated with first device 504, and may transmit a second paging request to base station 512, wherein the second paging request includes the paging reference identifier and a second device identifier associated with second device 506. In one aspect, the first device identifier may be a first TMSI (e.g., a first S-TMSI), and the second device identifier may be a second TMSI (e.g., a second S-TMSI).

[0104] When base station 512 receives a first paging request and a second paging request from core network device 522, base station 512 may determine the paging timing based on a paging reference identifier, and may, for example, transmit one or more paging messages to first device 504 and second device 506 during the paging timing in response to the first paging request and the second paging request. In one aspect, the one or more paging messages may include one or more paging messages for first device 504 and second device 506, including a first device identifier and a second device identifier associated with first device 504 and second device 506, respectively. In another aspect, the one or more paging messages may include a first paging message for first device 504 (including the first device identifier associated with first device 504) and / or a second paging message for second device 506 (including the second device identifier associated with second device 506), wherein the first paging message and the second paging message are transmitted within a shared paging timing. In one example, a paging message including a first device identifier and a second device identifier, a first paging message including a first device identifier, and / or a second paging message including a second device identifier may be transmitted within a shared paging timing. Therefore, for example, any paging message for the first device 504 and / or the second device 506 can be transmitted within a single paging time, and thus the UE 502 may need to wake up once to monitor paging to the first device 504 and the second device 506, rather than waking up twice to monitor paging to the first device 504 and paging to the second device 506 separately.

[0105] On one hand, base station 512 may further determine a paging frame based on the paging reference identifier, wherein base station 512 may transmit one or more paging messages to first device 504 and second device 506 during the paging timing in the paging frame. The one or more paging messages may include a first device identifier associated with first device 504 and a second device identifier associated with second device 506. Therefore, the specific device to which the one or more paging messages are to be sent can be indicated by the device identifiers (such as the first device identifier and the second device identifier) ​​included in the one or more paging messages.

[0106] In one aspect, the one or more paging messages may be broadcast by base station 512. In another aspect, UE 502 (e.g., via first device 504 and / or second device 506) may monitor paging messages from base station 512 and identify device identifiers to determine whether the paging message is for first device 504, second device 506, or both.

[0107] In one aspect, after a paging reference identifier is assigned to be associated with the first subscription and / or the first device 504, the UE 502 (e.g., via the first device 504 and / or the second device 506) can determine the paging timing and / or paging frame based on the paging reference identifier. In another aspect, the UE 502 and the base station 512 can use the same algorithm or formula to determine the paging timing and / or paging frame, such that the UE 502 can monitor these paging messages based on a shared paging timing and / or shared paging frame used by the base station 512 to transmit paging messages. Therefore, the UE 502 (e.g., via the first device 504 and / or the second device 506) can monitor one or more paging messages based on the paging timing and / or paging frame determined by the UE 502. On one hand, UE502 (e.g., via first device 504 and / or second device 506) may further associate the paging reference identifier with the second subscription and / or second device 506 to generate a paging reference identifier associated with the first subscription and / or first device 504 and with the second subscription and / or second device 506.

[0108] In one aspect, the paging reference identifier can be updated to an updated paging reference identifier associated with the first subscription and / or the first device 504 and with the second subscription and / or the second device 506. For example, one or more of the AMFs may change, which may trigger an update to the paging reference identifier. In the first approach explained above, the following process can be performed to update the paging reference identifier. The core network device 522 (e.g., via the first AMF 524) may assign a paging reference identifier to associate the updated paging reference identifier with the first subscription and / or the first device 504, and transmit the updated paging reference identifier to the first device 504 (e.g., via a network registration procedure and / or a device configuration update procedure). In another aspect, after receiving the updated paging reference identifier, the first device 504 may communicate the updated paging reference identifier to the second device 506. Subsequently, the second device 506 may transmit a registration update request for network registration updates to the core network device 522 (e.g., to the second AMF 526), ​​wherein the registration update request may include an updated paging reference identifier 504 associated with the first subscription and / or the first device. Upon receiving the registration update request, the core network device 522 (e.g., via the second AMF 526) may further associate the updated paging reference identifier with the second subscription and / or the second device 506. Thus, the updated paging reference identifier is associated with the first subscription and / or the first device 504 and with the second subscription and / or the second device 506.

[0109] In the second method explained above, the following process can be performed to update the paging reference identifier. First device 504 may assign an updated paging reference identifier to associate the updated paging reference identifier with a first subscription and / or first device 504, and may use the first subscription to transmit a first registration update request for network registration updates to core network device 522 (e.g., to a first AMF 524), wherein the first registration update includes the updated paging reference identifier associated with the first subscription and / or first device 504. In one aspect, after assigning the updated paging reference identifier to associate with the first subscription and / or first device 504, first device 504 may communicate the updated paging reference identifier to second device 506. Furthermore, second device 506 may use a second subscription to transmit a second registration update request to core network device 522 (e.g., to a second AMF 526), ​​wherein the second registration update includes the updated paging reference identifier to further associate the updated paging reference identifier with the second subscription and / or second device 506. Specifically, upon receiving a second registration update request, core network device 522 (e.g., via a second AMF 526) may further associate the updated paging reference identifier with the second subscription, such that the updated paging reference identifier is associated with the first subscription and / or the first device 504 and with the second subscription and / or the second device 506.

[0110] Figure 6 This is a flowchart 600 illustrating the process of paging multiple devices during a shared paging period according to one aspect of this disclosure. Figure 7 The process can be performed using a first device 604, a second device 606, a RAN 612, and a core network device 622. The first device 604 and the second device 606 can be a first SIM (e.g., first device 504) and a second SIM (e.g., second device 506), respectively. The first device 604 and the radio device 406 can be implemented within the UE 602 or can exist as separate radio devices capable of independent operation. The RAN 612 can be a base station, such as base station 512. The core network device 622 can include a first AMF 624 (e.g., first AMF 524) and a second AMF 626 (e.g., second AMF 526). In one aspect, flowchart 700 may correspond to the above references. Figure 5 The first way to explain.

[0111] First device 604 first performs a first network registration with core network device 622. Specifically, at 632, first device 604 uses its first subscription to send a first registration request for the first network registration to core network device 622 (e.g., to first AMF 624). Subsequently, first AMF 624 assigns a paging reference identifier (ID) to associate the paging reference identifier with the first subscription and / or first device 604, and may further assign a first device identifier (e.g., a first 5G GUTI) associated with first device 604. Core network device 622 (e.g., via first AMF 624) may store the paging reference identifier for UE 602. At 634, core network device 622 (e.g., via first AMF 624) uses, for example, the first subscription to send a first registration response including the paging reference identifier to first AMF 624.

[0112] When the first device 604 receives the first registration response, it may retrieve the paging reference identifier from the response and transmit it to the second device 606. In one aspect, the second device 606 may further associate the paging reference identifier with itself. At 634, the second device 606 uses its second subscription to transmit a second registration request to the core network (e.g., to the second AMF 626), the second registration request including the paging reference identifier. When the second AMF 626 receives the second registration request with the paging reference identifier, it may further associate the paging reference identifier with the second device 606 and assign a second device identifier (e.g., a second 5G GUTI) associated with the second device 606. At 638, the core network (e.g., via the second AMF 626) may, for example, use the second subscription to transmit a second registration response to the second device 606.

[0113] After completing the first and second network registrations, the first AMF 624 and the second AMF 626 may request RAN 612 to page the first device 604 and the second device 606. At 640, the core network device 622 (e.g., via the first AMF 624) may initiate a paging request for the first device 604. Subsequently, at 642, the core network device 622 (e.g., via the first AMF 624) may transmit a first paging request for the first device 604 to RAN 612, wherein the first paging request includes the paging reference identifier and the first device identifier. At 644, the core network device 622 (e.g., via the second AMF 626) may initiate a paging request for the second device 606. Subsequently, at 646, the core network device 622 (e.g., via the second AMF 626) may transmit a second paging request for the second device 606 to RAN 612, wherein the second paging request includes the paging reference identifier and the second device identifier.

[0114] When RAN 612 receives a paging reference identifier via a first paging request and / or a second paging request, RAN 612 may determine a paging timing and / or paging frame based on the paging reference identifier. First device 604 and / or second device 606 may also determine the paging timing and / or paging frame based on the paging reference identifier. Based on the paging timing and / or paging frame, at 648, RAN 612 transmits one or more paging messages to first device 604 and second device 606. As discussed above, the one or more paging messages may include: a paging message containing a first device identifier and a second device identifier, a paging message containing a first device identifier, and / or a paging message containing a second device identifier. First device 604 and / or second device 606 may monitor the paging messages during the paging timing and / or in the paging frame, and may receive one or more paging messages based on such monitoring and the one or more device identifiers included in each paging message.

[0115] Figure 7 This is a flowchart 700 illustrating the process of paging multiple devices during a shared paging period according to one aspect of this disclosure. Figure 7The process can be performed using a first device 704, a second device 706, a RAN 712, and a core network device 722. The first device 704 and the second device 706 can be a first SIM (e.g., first device 504) and a second SIM (e.g., second device 506), respectively. The first device 704 and the radio device 706 can be implemented within the UE 702 or can exist as separate radio devices capable of independent operation. The RAN 712 can be a base station, such as base station 512. The core network device 722 can include a first AMF 724 (e.g., first AMF 524) and a second AMF 726 (e.g., second AMF 526). In one aspect, flowchart 700 may correspond to the above references. Figure 5 The second way to explain.

[0116] First device 704 first performs a first network registration with core network device 722. Specifically, first device 704 may assign a paging reference identifier (ID) to associate the paging reference identifier with a first subscription and / or first device 704. At 732, first device 704 uses its first subscription to transmit a first registration request for first network registration to core network device 722 (e.g., to first AMF 724), wherein the first registration request includes the paging reference identifier. Subsequently, first AMF 724 may assign a first device identifier (e.g., a first 5G GUTI) associated with first device 704. Core network device 722 (e.g., via first AMF 724) may store the paging reference identifier for UE 702. At 734, core network device 722 (e.g., via first AMF 724) transmits a first registration response to first AMF 724, for example, using the first subscription.

[0117] In one aspect, the first device 704 may convey a paging reference identifier to the second device 706. In another aspect, the second device 706 may further associate the paging reference identifier with itself. After the first device 704 receives the first registration response, at 734, the second device 706 uses its second subscription to transmit a second registration request to the core network (e.g., to the second AMF 726), wherein the second registration request includes the paging reference identifier. When the second AMF 726 receives the second registration request with the paging reference identifier, the second AMF 726 may further associate the paging reference identifier with the second device 706 and may assign a second device identifier (e.g., a second 5G GUTI) associated with the second device 706. At 738, the core network (e.g., via the second AMF 726) may, for example, use the second subscription to transmit a second registration response to the second device 706.

[0118] After completing the first and second network registrations, the first AMF 724 and the second AMF 726 may request RAN 712 to page the first device 704 and the second device 706. At 740, the core network device 722 (e.g., via the first AMF 724) may initiate a paging request for the first device 704. Subsequently, at 742, the core network device 722 (e.g., via the first AMF 724) may transmit a first paging request for the first device 704 to RAN 712, wherein the first paging request includes the paging reference identifier and the first device identifier. At 744, the core network device 722 (e.g., via the second AMF 726) may initiate a paging request for the second device 706. Subsequently, at 746, the core network device 722 (e.g., via the second AMF 726) may transmit a second paging request for the second device 712 to RAN 706, wherein the second paging request includes the paging reference identifier and the second device identifier.

[0119] When RAN 712 receives the paging reference identifier via a first paging request and / or a second paging request, RAN 712 may determine the paging timing and / or paging frame based on the paging reference identifier. First device 704 and / or second device 706 may also determine the paging timing and / or paging frame based on the paging reference identifier. Based on the paging timing and / or paging frame, at 748, RAN 712 transmits one or more paging messages to first device 704 and second device 706. As discussed above, one or more paging messages may include: a paging message containing a first device identifier and a second device identifier, a paging message containing a first device identifier, and / or a paging message containing a second device identifier. First device 704 and / or second device 706 may monitor the paging messages during the paging timing and / or in the paging frame, and may receive one or more paging messages based on such monitoring and the one or more device identifiers included in each paging message.
