Paging method and apparatus

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202411021659.5, filed on July 26, 2024, and entitled "A paging method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a paging method and apparatus. BACKGROUND

[0004] A network can initiate paging to a terminal device in a radio resource control (RRC) idle state or an RRC inactive state. The terminal device can detect paging-related messages at a paging occasion (PO).

[0005] The fifth generation (5G) new radio (NR) technology follows the discontinuous reception (DRX) mechanism in the long term evolution (LTE) technology. The basic mechanism of DRX is to configure a terminal device with a DRX cycle, and in an on duration, the terminal device normally detects a PDCCH, and in an opportunity for DRX, the terminal device can enter a sleep state and does not receive the PDCCH to reduce power consumption. A terminal device in an idle state or an inactive state can "wake up" to receive paging-related messages at a corresponding PO.

[0006] For a dual-card terminal device, behaviors such as PO detection and decoding of paging messages need to be performed twice, and the duration of "waking up" is also twice that of a single-card terminal device. It can be seen that the power consumption of a dual-card terminal device is large, which shortens the standby time of the dual-card terminal device and leads to poor user experience. SUMMARY

[0007] The paging method and apparatus provided by the embodiments of the present application are used to reduce the power consumption of a multi-user identity terminal device.

[0008] In a first aspect, the present application provides a paging method, the execution subject of the method can be a terminal device, or a chip or circuit on the terminal device side. Taking the terminal device as an example, the method comprises: sending a first message to a core network device in a first user identity, the first message being used for requesting / indicating that a paging message corresponding to a second user identity is received by the first user identity; receiving first information from an access network device in the first user identity, the first information being used for indicating that the second user identity is paged.

[0009] The present application associates two user identities of a terminal device, so that the paging message of the second user identity is received by the first user identity, that is, the first user identity detects the paging-related message of itself and the second user identity on the PO of itself, and the second user identity does not need to wake up to detect the paging-related message on the PO of the second user identity. Compared with the mode in which both user identities need to detect the PO and decode the paging message, the present application can reduce the power consumption of the terminal device, improve the standby time of the multi-user identity terminal device, and further improve the user experience.

[0010] In a possible design, the first message used for requesting / indicating that the paging message corresponding to the second user identity is received by the first user identity comprises: the first message carrying identification information corresponding to the second user identity. In this way, it is defaulted that the request message is sent by the proxy UE, and the first message does not need to indicate the role of the first user identity by additional information, so that the signaling overhead can be saved.

[0011] In a possible design, the first message used for requesting / indicating that the paging message corresponding to the second user identity is received by the first user identity comprises: the first message carrying identification information corresponding to the second user identity and second information, the second information being used for indicating that the first user identity is a proxy terminal. In this way, the accuracy of association can be improved.

[0012] In a possible design, the first user identity and the second user identity correspond to the same terminal device.

[0013] In a possible design, the paging occasion corresponding to the first user identity is different from the paging occasion corresponding to the second user identity.

[0014] In a possible design, the first information is carried in a paging message, and the paging message is received by the first user identity in a paging occasion corresponding to the first user identity. In this design, the first user identity not only detects the paging-related message of itself on the PO of itself, but also detects the paging-related message of UE2.

[0015] In a possible design, the first information is the identification of the second user identity, or the first information is a predefined bit / field, which is used for indicating whether the second user identity is paged.

[0016] In a possible design, the first information is indicated by an RRC message sent by the access network device.

[0023] The application associates two user identities of a terminal device, so that a message related to paging of the second user identity is received through the first user identity, that is, the first user identity detects the message related to paging of itself and the second user identity on the PO of itself, and the second user identity does not need to wake up to detect the message related to paging on the PO of the second user identity. Compared with the mode in which both the user identities need to detect the PO and decode the paging message, the application can reduce the power consumption of the terminal device, improve the standby time of the multi-user identity terminal device, and thus improve the user experience.

Taking the core network device as an example, the method includes: receiving first information from a first user identity, where the first information is used to adjust the position of a paging occasion of the first user identity; and sending third information to an access network device, where the third information is used to indicate information of the paging occasion of the first user identity, and the third information is determined according to the first information.

[0104] The method adjusts the position of the PO of one or more user identities, so that the PO positions of at least two user identities completely overlap or partially overlap, thereby achieving receiving paging messages of multiple user identities using one set of hardware, avoiding performing multiple times of paging reception using multiple sets of hardware, or performing multiple times of paging using one set of hardware, thereby reducing power consumption of a terminal device, improving standby time of a dual-card terminal device, and further improving user experience.

[0107] In a possible design, the third information includes identifier information corresponding to the first user identity, or a remainder obtained by dividing the identifier information corresponding to the first user identity by 1024.

[0108] In a possible design, the third information is included in a paging message, and / or the third information is included in RRC INACTIVE core network assistance information.

[0109] In a possible design, the method further includes: sending, to the first user identity, second information, where the second information indicates confirmation / permission of adjusting the position of the paging occasion of the first user identity, and / or information of the adjusted paging occasion of the first user identity. In this way, the behavior of the terminal side and the network side can be aligned.

[0110] In a possible design, the method further includes: receiving a non-access stratum (NAS) message from the first terminal, where the NAS message is used to indicate cancellation / cancellation of one or more of the first information. In this way, the flexibility of PO adjustment can be improved.

[0139] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0140] In the following, some terms in the embodiments of the present application are explained to facilitate the understanding of the skilled in the art.

[0141] 1) Multi-card terminal device

[0142] The multi-card terminal device can also be referred to as a multi-user identity terminal device. The terminal device can have multiple user identities. For example, the terminal device can have two user identities (such as a first user identity and a second user identity), and the terminal device works in a first communication system with the first user identity and works in a second communication system with the second user identity.

[0143] In this application, the "user identity" (such as the first user identity, the second user identity) is a logical concept, and the "user identity" can correspond to a Subscriber Identity Module (SIM) card, or a subscription user information, or a virtual SIM card, or a user identifier (such as an international mobile subscriber identity (IMSI) / temporary mobile subscriber identity (TMSI)), and is not limited to a natural person user or a physical terminal (mobile phone) and the like. The user identity can be registered on the network, or can not be registered on the network, and not being registered on the network also means that the network can not perceive the user identity of the terminal device (for example, the terminal device can receive the broadcast data of the network device in a certain user identity). From the perspective of the network side, different "user identities" can correspond to different communication entities served by the network side in a logical sense. For example, a terminal with a dual-SIM card is two communication entities for the network side. For another example, when the "user" corresponds to the SIM card or the subscription user information, the network side will identify two terminals with different SIM cards or different subscription user information as two different communication entities, and will also identify the same terminal device with multiple different SIM cards or multiple subscription user information as multiple different communication entities, even though in practice, the terminal with multiple different SIM cards or multiple subscription user information is only one physical entity. The communication systems corresponding to different user identities can belong to the same public land mobile network (PLMN) or different PLMNs, and the communication systems corresponding to different user identities can belong to the same operator network or different operator networks.

[0144] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0145] Also, unless otherwise stated, the ordinal numbers “first”, “second”, etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority or importance of the multiple objects.

[0146] The foregoing introduces some concepts related to the embodiments of the present application. The following introduces the technical background related to the embodiments of the present application.

[0147] The network can initiate paging to a terminal device in a radio resource control (RRC) idle state or an RRC inactive state. The terminal device can detect paging-related messages at a paging occasion (PO).

[0148] The fifth generation (5G) new radio (NR) technology follows the discontinuous reception (DRX) mechanism in the long term evolution (LTE) technology. The basic mechanism of DRX is to configure a terminal device with a DRX cycle. In the on duration, the terminal device normally detects PDCCH. In the opportunity for DRX, the terminal device can enter a sleep state and does not receive PDCCH to reduce power consumption. A terminal device in an idle state or an inactive state can “wake up” to receive paging-related messages at a corresponding PO.

[0149] For a dual-card terminal device, the two user identities of the terminal device are independent of each other, so the behaviors such as PO detection and decoding of paging messages need to be done twice, and the length of time for “waking up” is also twice that of a single-card terminal device. It can be seen that the power consumption of a dual-card terminal device is large, which shortens the standby time of the dual-card terminal device and leads to poor user experience.

[0150] Based on this, the embodiments of the present application provide a paging method and device for reducing the power consumption of a terminal device with multiple user identities. The method and the device are based on the same concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0151] The paging method provided in the application can be applied to various communication systems, for example, can be internet of things (IoT), narrow band internet of things (NB-IoT), LTE, can also be a fifth generation (5G) communication system, can also be a hybrid architecture of LTE and 5G, can also be a 5G NR system and a future communication system, etc.

[0152] The paging method provided in the embodiments of the application can be applied to a system comprising a terminal device and a network device, wherein the terminal device can be a terminal device with multiple user identities, such as a multi-card terminal device. The system can further comprise a core network device. In the system, the multiple user identities of the terminal device can be connected to the same network device, or can be connected to different network devices. The network devices connected by the multiple user identities of the terminal device can be connected to the same core network device, or can be connected to different core network devices.

[0153] The communication system can be a 5G NR communication system. The interface between the core network device and the network device is an NG interface, and different network devices are connected through an Xn interface. Taking the network device as a gNB or ng-eNB and the core network device as an access and mobility management function (AMF) / user plane function (UPF) as an example, the connection relationship between the AMF / UPF and the network device, and between different AMF / UPF and network devices can be as shown in FIG. 1.

[0154] The communication system can be an LTE communication system. The interface between the core network device and the network device is an S1 interface, and different network devices are connected through an X2 interface. Taking the network device as an eNB or en-gNB and the core network device as an MME / S-GW as an example, the connection relationship between the mobility management entity (MME) and / or serving gateway (S-GW) and the network device, and between different MME / S-GW and network devices can be as shown in FIG. 2.

[0155] The terminal device is also referred to as terminal, user equipment (UE), mobile station (MS), mobile terminal (MT) and the like. The terminal device can be a device providing voice and / or data connectivity to users. The terminal device can communicate with one or more core networks through access network devices. The terminal device can be deployed in terrestrial environments, including indoor, outdoor, handheld, and / or vehicular; can be deployed on water surface (such as ships, etc.); and can be deployed in air (such as airplanes, balloons, and aerial vehicles, etc.). The terminal device includes a handheld device having wireless connection capability, other processing devices connected to wireless modems, and vehicle-mounted devices, etc. The terminal device can be a portable, pocket, hand-held, computer-embedded, or car-mounted mobile device. Some examples of the terminal device are: personal communication service (PCS) phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), wireless web camera, mobile phone, tablet computer, notebook computer, palm computer, mobile internet device (MID), wearable device such as smart watch, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, terminal in Internet of Things (IoT) system, wireless terminal in self driving, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city such as smart fuel dispenser, terminal device on high-speed rail, and wireless terminal in smart home such as smart speaker, smart coffee machine, smart printer, etc. The terminal device in the present application can have multiple user identities.

[0156] In the embodiments of the present application, the communication device for implementing the function of the terminal device can be a terminal device, a terminal device with partial function of a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system, which can be installed in the terminal device or used in matching with the terminal device. In the embodiments of the present application, the chip system can be composed of a chip or can include a chip and other discrete devices. In the technical solutions provided in the embodiments of the present application, the communication device for implementing the function of the terminal device is taken as an example for description.

[0157] The access network device refers to a radio access network (RAN) device. The RAN can be a 3GPP related cellular system, for example, a 5G / new radio (NR) mobile communication system or a future-oriented evolution system (for example, a 6G mobile communication system). The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a virtualized RAN (vRAN), etc. The RAN can also be a communication system in which two or more of the above systems are fused. The RAN device can also be referred to as a RAN node, a RAN entity, or an access node, etc.

[0158] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation access network device in a 6G mobile communication system, an access network device in a future mobile communication system, etc. The RAN node can be a macro access network device, a micro access network device, an indoor station, a relay node, a donor node / host node, or a radio controller, etc. The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the RAN node in the V2X technology can be a road side unit (RSU).

[0159] In another possible scenario, a RAN node can be a module or unit that completes part of the functions of an access network device; or multiple RAN nodes cooperate to assist a terminal device to implement wireless access, and different RAN nodes respectively implement part of the functions of an access network device. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU), etc. The functions of the CU can be implemented by one entity, or can also be implemented by different entities. For example, the functions of the CU can be further divided, that is, the control plane and the user plane are separated and implemented by different entities, respectively, as a control plane CU entity (that is, a CU-control plane (CP) entity) and a user plane CU entity (that is, a CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the RAN node. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a baseband unit (BBU). Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0160] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application.

[0161] The CU and the DU can be configured according to protocol layer functions of a wireless network implemented thereby: for example, the CU is configured to implement functions of a packet data convergence protocol (PDCP) layer and protocol layers thereabove (such as a radio resource control (RRC) layer and / or a service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement functions of protocol layers below the PDCP layer (such as a radio link control (RLC), a media access control (MAC) layer, and / or a physical (PHY) layer, etc.). For specific descriptions of the various protocol layers described above, reference can be made to relevant technical specifications of the 3GPP or technical specifications of other applicable communication protocols.

[0162] When the RAN is an O-RAN, it can also have an artificial intelligence (AI) function, for example, the O-RAN includes an intelligent controller. The intelligent controller can be a non-real time RAN intelligent controller (non-RT RIC / non-RT RIC / NRT RIC), or a near-real time RAN intelligent controller (near-RT RIC / near-RT RIC / nRT RIC). The non-real time RIC can be used to implement non-real time intelligent management of the RAN, can implement a workflow including model training and model updating, and guide applications / functions in the nRT RIC based on a policy. The near-real time RIC can be used to implement near-real time intelligent management of the RAN. Through data collection and related operations on an E2 interface, near-real time control and optimization of modules and resources of the O-RAN are implemented.

[0163] In the embodiments of the present application, the device for implementing the function of the access network device can be the access network device itself, or a device capable of supporting the access network device to implement the function, such as a chip system or a combination device or component that can implement the function of the access network device, which can be installed in the access network device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the access network device.

[0164] The core network device can include one or more of the following network elements: an authentication server function (AUSF) network element, a network exposure function (NEF) network element, a policy control function (PCF) network element, a unified data management (UDM) network element, a unified data repository (UDR), a network repository function (NRF) network element, an access and mobility management function (AMF) network element, a session management function (SMF) network element, an access network, and a user plane function (UPF) network element, and the like. In a possible implementation method, the core network device can also include an application function (AF) network element.

[0165] The UPF network element is an interface with a data network, and performs functions such as user plane data (such as packet data) forwarding, quality of service (QoS) control, session / stream-based charging statistics, and bandwidth limitation.

[0166] The AMF network element mainly performs a registration process during user access, and performs functions such as location management during user movement, access authentication / authorization, and the like. In addition, it is also responsible for transmitting user policies between the UE and the PCF.

[0167] The SMF network element mainly performs a session connection corresponding to user-initiated services, and provides specific services for users, such as data packet forwarding policies and QoS policies between the SMF and the UPF, and the like.

[0168] The AUSF network element is mainly responsible for authenticating users and determining the legitimacy of user equipment to determine whether to allow the user or the equipment to access the network.

[0169] The UDM network element is mainly responsible for storing subscription data of user equipment, user access authorization, and the like.

[0170] The UDR is mainly responsible for access functions of types of data such as subscription data, policy data, and application data.

[0171] PCF network element, mainly responsible for issuing service-related policies to AMF or SMF.

[0172] NEF network element, mainly used to support the opening of capabilities and events.

[0173] AF network element, mainly to pass the application side's demand for the network side to the PCF, so that the PCF generates the corresponding policy. The AF can be a third-party functional entity, or an application service deployed by the operator, such as an internet protocol (IP) multimedia subsystem (IMS) voice call service.

[0174] NRF network element, which can be used to provide network element discovery functions, and provide network element information corresponding to the network element type based on the request of other network elements. The NRF also provides network element management services, such as network element registration, update, deregistration, and network element state subscription and push.

[0175] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions provided by the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0176] The terminal device involved in the present application can support a first user identity and a second user identity. The first user identity and the second user identity can be understood as two logical terminals. For the sake of description, the following is described from the perspective of logical terminals, i.e., UE1 is the logical terminal corresponding to the first user identity of the terminal device, and the behavior of UE1 (such as processing information / messages / data, transmitting / receiving information / messages / data, etc.) can be understood as the behavior of the terminal device in the first user identity. UE2 is the logical terminal corresponding to the second user identity of the terminal device, and the behavior of UE2 (such as processing information / messages / data, transmitting / receiving information / messages / data, etc.) can be understood as the behavior of the terminal device in the second user identity.

[0177] It should be understood that the embodiments of the present application only take the terminal device supporting two user identities as an example for illustration, and do not limit the number of user identities supported by the terminal device.

[0178] The messages exchanged between the UE (such as UE1 or UE2) and the core network device in the present application can be in the form of NAS messages, which are transparently transmitted by the access network device. Alternatively, the messages exchanged between the UE (such as UE1 or UE2) and the core network device can also be in the form of forwarding by the access network device.

[0179] For example, in the method of FIG. 3, UE1 sends a first message to the core network device, the first message can be a NAS message, and the first message can be transparently transmitted by the access network device to the core network device. Alternatively, UE1 can send the first message to the access network device, and the access network device forwards the first message to the core network device. For example, the access network device can forward the information indicated by the first message to the core network device after analyzing the first message, or the access network device can send the first message to the core network device in a container of message A, where message A is a message sent by the access network device to the core network device.

[0180] For another example, in the method of FIG. 3, the core network device sends a feedback message of the first message to UE1, the feedback message can be a NAS message, and the feedback message can be transparently transmitted by the access network device to the terminal device. Alternatively, the core network device can send the feedback message of the first message to the access network device, and the access network device forwards the feedback message to the terminal device. For example, the access network device can forward the information indicated by the feedback message to the terminal device after analyzing the feedback message, or the access network device can send the feedback message to the terminal device in a container of message B, where message B is a message sent by the access network device to the terminal device.

[0181] Other interaction messages are similar and will not be described here.

[0182] The following describes a technical feature related to an embodiment of the present application.

[0183] The following describes a paging method. By associating UE1 and UE2, the paging message of UE2 is received by UE1, that is, UE1 detects the paging message of UE1 and UE2 on the PO of UE1, and UE2 does not need to wake up to detect the paging message of UE2 on the PO of UE2. Compared with the method in which UE1 and UE2 both need to detect the PO and decode the paging message, the power consumption of the terminal device can be reduced, the standby time of the multi-user identity terminal device can be improved, and the user experience can be improved.

[0184] For the convenience of describing the scheme, the following will refer to the behavior of receiving the paging message of other user identities as proxy paging or proxy, and the UE that performs the action of receiving the paging message of other user identities will be referred to as a proxy UE (or proxy party or proxy terminal), and the UE that does not perform the action of receiving the paging message but is actually paged will be referred to as a proxy UE (or proxy party or proxy terminal). For example, in the implementation in which UE1 receives the paging message of UE2, UE1 is a proxy UE, and UE2 is a proxy UE. It should be understood that the "proxy" is an exemplary description, and is not specifically limited here.

[0185] It should be noted that, in the present application, "receiving a paging message" can also be understood as receiving paging information, or receiving a message or information related to paging, for example, receiving a paging message of UE2 by UE1 can be understood as receiving a paging message of UE2 by UE1, or can also be understood as receiving a message / information indicating paging UE2 by UE1, or can also be understood as receiving paging-related message / information of UE2.

[0186] As shown in FIG. 3, a flowchart of a paging method provided by an embodiment of the present application is shown. The method comprises:

[0187] S301, UE1 sends a first message to a core network device. Correspondingly, the core network device receives the first message from UE1.

[0188] The first message is used to request / indicate that UE1 receives a paging message of UE2; wherein the paging message of UE2 can come from the core network device, i.e., the paging of UE2 is initiated by the core network device, or come from the access network device, i.e., the paging of UE2 is initiated by the access network device.

[0189] The first message can request / indicate that UE1 receives the paging message corresponding to UE2 in one of the following ways:

[0190] Method 1: the first message carries the identification information of UE2. In this method, it is by default that the first message is sent by a proxy UE, i.e., UE1 sending the first message is a proxy UE, and the identification information of UE2 is carried in the first message to indicate that UE2 is a proxy UE, thereby realizing the request / indication to the core network device that UE1 receives the paging message corresponding to UE2.

[0191] Method 2: the first message carries the identification information corresponding to UE2 and second information, and the second information is used to indicate that UE1 is a proxy UE. The difference between this method and method 1 is that, in method 1, it is by default that the first message is sent by a proxy UE, and the first message does not need additional information to indicate the role of UE1, while in method 2, the role of UE1 is indicated as a proxy UE by the second information.

[0192] Optionally, the core network device can further send a feedback message of the first message to UE1 after receiving the first message, where the feedback message is used to confirm / allow UE1 to receive the paging message of UE2. For example, the feedback message can indicate the confirmation / allowance of UE1 to receive the paging message of UE2 by carrying the identification information of UE2. If the feedback message does not carry the identification information of UE2, it means that the core network device does not confirm / allow UE1 to receive the paging message of UE2. For another example, the feedback message can indicate the confirmation / allowance of UE1 to receive the paging message of UE2 by setting a predefined bit / field to a first value. If the feedback message sets the predefined bit / field to a second value, it means that the core network device does not confirm / allow UE1 to receive the paging message of UE2.

[0193] The above process makes UE1 and the core network device determine that the paging message of UE2 is received by UE1 through the interaction between the core network device and UE1.

[0194] Optionally, the core network device can further interact with UE2 to make UE2 determine that the paging message of UE2 is received by UE1.

[0195] For example, the core network device can send a seventh message to UE2, where the seventh message is used to request / configure / indicate that the paging message of UE2 is received by UE1. UE2 can further send a feedback message of the seventh message to the core network device, where the feedback message is used to confirm / allow UE1 to receive the paging message of UE2. The indication manner of the feedback message of the seventh message is similar to that of the feedback message of the first message, which is not repeated here.

[0196] For another example, UE2 can send the identification information corresponding to UE1 and fourth information to the core network device, where the fourth information is used to indicate that UE2 is a proxy UE. Optionally, the core network device can send a feedback message to UE2, where the feedback message is used to confirm / allow UE1 to receive the paging message of UE2. The indication manner of the feedback message is similar to that of the feedback message of the first message, which is not repeated here.

[0197] The above manner makes UE2 determine that the paging message of UE2 is received by UE1 through the interaction between the core network device and UE2, so that UE2 can not calculate the PO and wake up at the PO position to detect the paging-related message / information.

[0198] The UE1 and the UE2 can be associated through S301, so that the paging message of the UE2 is received through the UE1. S301 is one of the ways to associate the UE1 and the UE2, and the UE1 and the UE2 can be associated in another two ways. Among them, the first way is similar to the way of S301, and the proxy UE and the agent UE are determined by the terminal side. The difference is that the way of S301 is initiated by the proxy UE, and the first way is initiated by the agent UE. The second way is different from the first way and the way of S301 in that the proxy UE and the agent UE are determined by the core network device.

[0199] The following describes another two ways to associate the UE1 and the UE2.

[0200] In the first way, the UE2 sends a fourth message to the core network device. The fourth message is used to request / indicate that the UE1 receives the paging message corresponding to the UE2.

[0201] The fourth message can request / indicate that the UE1 receives the paging message corresponding to the UE2 in one of the following ways:

[0202] In way 3, the fourth message carries the identification information of the UE1. In this way, the fourth message is sent by the agent UE by default, that is, the UE2 sending the fourth message is the agent UE. By carrying the identification information of the UE1 in the fourth message, it is indicated that the UE1 is the proxy UE, so as to request / indicate the core network device to receive the paging message corresponding to the UE2 by the UE1.

[0203] In way 4, the fourth message carries the identification information corresponding to the UE1 and the fourth information, and the fourth information is used to indicate that the UE2 is the agent UE. The difference between way 4 and way 3 is that the fourth message is sent by the agent UE by default in way 3, and the role of the UE2 does not need to be indicated by additional information, while the role of the UE2 is indicated to be the agent UE by the fourth information in way 4.

[0204] Optionally, the core network device can further send a feedback message of the fourth message to the UE 2 after receiving the fourth message, and the feedback message is used to confirm / allow the UE 1 to receive the paging message of the UE 2. For example, the feedback message can indicate the confirmation / allowance of the UE 1 to receive the paging message of the UE 2 by carrying the identification information of the UE 1. If the feedback message does not carry the identification information of the UE 1, it means that the core network device does not confirm / allow the UE 1 to receive the paging message of the UE 2. For another example, the feedback message can indicate the confirmation / allowance of the UE 1 to receive the paging message of the UE 2 by setting a predefined bit / field to a first value. If the feedback message sets the predefined bit / field to a second value, it means that the core network device does not confirm / allow the UE 1 to receive the paging message of the UE 2.

[0205] The above manner makes the UE 2 determine that the paging message of the UE 2 is received by the UE 1 through the interaction between the core network device and the UE 2, so that the UE 2 can not calculate the PO and wake up at the PO position to detect the paging-related message.

[0206] Optionally, the core network device can further interact with the UE 1 to make the UE 1 determine that the paging message of the UE 2 is received by the UE 1.

[0207] For example, the core network device can further send an eighth message to the UE 1, and the eighth message is used to request / configure / indicate the UE 1 to receive the paging message of the UE 2. The UE 1 can further send a feedback message of the eighth message to the core network device, and the feedback message is used to confirm / allow the UE 1 to receive the paging message of the UE 2. The indication manner of the feedback message of the eighth message is similar to the indication manner of the feedback message of the first message, which will not be repeated here.

[0208] For another example, the UE 1 can send the identification information corresponding to the UE 2 and second information to the core network device, and the second information is used to indicate that the UE 2 is a proxy UE. Optionally, the core network device can send a feedback message to the UE 1, and the feedback message is used to confirm / allow the UE 1 to receive the paging message of the UE 2. The indication manner of the feedback message is similar to the indication manner of the feedback message of the first message, which will not be repeated here.

[0209] The above manner makes the UE 1 determine that the paging message of the UE 1 is received by the UE 1 through the interaction between the core network device and the UE 1.

[0210] In the second manner, the UE 1 sends the second message to the core network device, and / or the UE 2 sends the fifth message to the core network device.

[0211] The second message is used to indicate that the UE 1 and the UE 2 correspond to the same terminal device, or the second message is used to indicate / request the association of the UE 1 and the UE 2. Optionally, the second message can carry the identification information of the UE 2.

[0212] The fifth message is used to indicate that UE1 and UE2 correspond to the same terminal device, or the fifth message is used to indicate / request the association of UE1 and UE2. Optionally, the fifth message can carry the identification information of UE1.

[0213] In this manner, the core network device can further send a third message to UE1 and / or a sixth message to UE2, the third message being used to indicate / configure UE1 to receive the paging message corresponding to UE2, and the sixth message being used to indicate / configure UE1 to receive the paging message corresponding to UE2.

[0214] The association relationship between UE1 and UE2 or the relationship between UE1 and the paging agent of UE2 can be established at the core network side by any one of the manners described in S301, the first manner, and the second manner. The core network device can save or record the association relationship between UE1 and UE2 or the relationship between UE1 and the paging agent of UE2. The association relationship between UE1 and UE2 can be the association of the permanent identifier of the UE (for example, the IMSI or international mobile equipment identity (IMEI) of the UE) or the association of the temporary identifier of the UE (for example, the 5G-S-TMSI of the UE).

[0215] Optionally, UE1 or UE2 can further request the core network device to update the association relationship thereof. For example, UE1 can send third information to the core network device, the third information indicating to update the association relationship of UE1, or the third information indicating that UE1 has the association relationship. Correspondingly, the core network device can associate the updated identification information of UE1 with the identification information of UE2. For another example, UE2 can send fifth information to the core network device, the fifth information indicating to update the association relationship of UE2, or the fifth information indicating that UE2 has the association relationship. Correspondingly, the core network device can associate the updated identification information of UE2 with the identification information of UE1.

[0216] For example, if the core network device stores the association relationship between UE1 and UE2 through the 5G-S-TMSI of the UE. Each time the UE (e.g., UE1 or UE2) enters the connected state, the core network device can reassign a 5G-S-TMSI to the UE. The UE can report the previously assigned 5G-S-TMSI to the core network device, and the core network device reassigns a new 5G-S-TMSI to the UE. In this scenario, the core network device can update the association relationship between UE1 and UE2. For example, taking UE1 as an example, UE1 reports the previously assigned 5G-S-TMSI to the core network device after entering the connected state, and the core network device reassigns a new 5G-S-TMSI to UE1 and associates the new 5G-S-TMSI of UE1 with the 5G-S-TMSI of UE2. Optionally, when UE1 reports the previously assigned 5G-S-TMSI to the core network device, UE1 can also indicate that UE1 has an association relationship or indicate that the association relationship corresponding to UE1 needs to be updated. The process of updating the association relationship of UE2 is similar to that of UE1, which will not be described here.

[0217] It should be noted that the association of UE1 and UE2 is an optional process.

[0218] As an optional solution, the PO corresponding to UE1 and the PO corresponding to UE2 can be different.

[0219] For example, the identification information of the UE (e.g., UE1, UE2) in this application can be the IMSI or 5G S-temporary mobile subscription identifier (5G-S-TMSI) corresponding to the UE.

[0220] This application only takes UE1 as an example to proxy the paging message of UE2, that is, UE1 receives the paging message of UE2, and in specific implementation, the terminal device (i.e., the terminal device corresponding to the first user identity (UE1) and the second user identity (UE2)) can determine which user identity to proxy paging (i.e., receive the paging message) and indicate / request to the core network device, for example, the terminal device interacts the association relationship through the above process. For example, if both user identities of the terminal device are in idle state or inactive state, the terminal device can determine that the user identity with shorter DRX cycle proxies paging. Alternatively, if one user identity of the terminal device is in connected state (e.g., CN connected state) and the other user identity is in idle state (e.g., CN idle state), the terminal device can determine that the user identity in connected state proxies paging.

[0221] Alternatively, it can be specified by the protocol or configured by which user identity agent to page, for example, the protocol can define to page by the user identity agent with short DRX cycle, or the protocol can define to page by the user identity agent in connected state.

[0222] When the core network device needs to page UE2, since the core network device knows the association relationship of UE1 and UE2 or the relationship of UE1 and UE2 paging agent, the core network device can indicate the paging time of UE2 to the access network device, and can indicate the information of UE1 paging agent, which can be referred to the related description of S302 below, so that the access network device knows the relationship of UE1 and UE2 paging agent, and then sends the paging of UE2 through UE1, without the need for UE2 to receive the paging by itself, which can be referred to the related description of S303 below.

[0223] S302, the core network device indicates to the access network device to receive the paging message of UE2 by UE1.

[0224] In an implementation manner, the core network device can send sixth information to the access network device, and the sixth information is used to indicate to receive the paging message of UE2 by UE1. For example, the sixth information can include the identification information corresponding to UE1 or the remainder of the identification information corresponding to UE1 divided by 1024, that is, the identification information corresponding to UE1 is subjected to modulo operation of 1024, which can also be expressed as (the identification corresponding to UE1) mod 1024, and mod is the modulo operation.

[0225] Optionally, the core network device can send the sixth information through the paging message and / or RRC INACTIVE core network assistance information.

[0226] An example is that UE1 is in idle state or inactive state or connected state, and UE2 is in idle state (i.e. CN idle and RAN idle) or inactive state (i.e. CN connected and RAN idle). The core network device sends the paging message of UE2 to the access network device, and sends the information of UE1 paging agent at the same time. For example, the information of UE1 paging agent can include the identification of UE1 (such as 5G-S-TMSI) or the PO related information of UE1 (such as the value of 5G-S-TMSI mod 1024 of UE1). When the access network device receives the paging message of UE2 and the information of UE1 paging agent, it can be determined that the paging message of UE2 needs to be sent through UE1.

[0227] In another example, UE2 is in inactive state (i.e. CN connected and RAN idle), and UE1 is in inactive state. The core network device sends RRC INACTIVE core network assistance information to the access network device, and the RRC INACTIVE core network assistance information can include information of a UE1 paging agent. For example, the information of the UE1 paging agent includes an identifier (e.g. 5G-S-TMSI) of the UE1 or PO-related information (e.g. a value of 5G-S-TMSI mod 1024 of the UE1).

[0228] In another implementation, the core network device can send seventh information to the access network device through an interface corresponding to the UE1, the interface being used to connect the access network device and the core network device and being used to transmit data / information of the UE1. The seventh information indicates that the UE2 is paged, or the seventh information indicates that data of the UE2 arrives.

[0229] In this way, the core network device indicates, through the interface of the UE1, to the access network device that the UE2 is paged or data of the UE2 arrives, and the access network device can determine to receive a paging message of the UE2 by the UE1 after receiving the relevant content of the UE2 through the interface of the UE1. Alternatively, the access network device can consider that the seventh information received through the interface of the UE1 is data / information that needs to be sent to the UE1, and the access network device does not need to understand the content or meaning of the seventh information (i.e. does not need to understand that the content of the information is that the UE2 is paged or data of the UE2 arrives), but directly sends the seventh information to the UE1, and the UE1 determines that the UE2 is paged after analyzing the seventh information.

[0230] For example, the UE1 is in an inactive state / connected state, and the UE2 is in an idle state or an inactive state. The core network device sends information to the access network device through an interface of the UE1 to indicate that the UE2 is paged or data of the UE2 arrives. Specifically, the core network device can generate seventh information, which can include identifier information of the UE2, to indicate that the UE2 is paged or data of the UE2 arrives, and the access network device can determine to send a paging message of the UE2 by the UE1 after receiving the seventh information through the interface of the UE1. Alternatively, the access network device can also send the seventh information to the UE1, and the UE1 analyzes the seventh information to determine that the UE2 is paged.

[0231] Optionally, if UE2 is in the inactive state and UE1 is in the connected state, the access network device can further indicate to the core network device whether UE1 is a proxy UE or a proxied UE.

[0232] At S303, the access network device sends the first information to UE1. Correspondingly, UE1 receives the first information from the access network device.

[0233] The first information is used to indicate that UE2 is paged.

[0234] As an example, the access network device can send a paging-related message on the PO corresponding to UE1, where the paging-related message includes paging information, and the paging-related message carries the first information. The access network device can determine the PO of UE1 as the PO location for sending the paging-related message of UE2 according to the information of UE1 paging proxy, and send the paging-related message of UE2 on the PO of UE1 without the need to calculate the PO location of UE2 itself. UE1 not only detects the paging-related message of itself on its own PO, but also detects the paging-related message of UE2.

[0235] In an example, the first information can be the identifier of UE2, or the first information can also be a predefined bit / field / information, which is used to indicate whether UE2 is paged.

[0236] Taking the first information as the identifier information of UE2 as an example, when UE1 receives the paging-related message on its own PO, UE1 needs to check not only its own identifier information but also the identifier information of UE2. If the paging-related message includes the identifier information of UE2, UE1 can notify UE2 that it is paged.

[0237] Taking the first information as a predefined bit / field / information as an example, when UE1 receives the paging-related message on its own PO, UE1 only needs to check its own identifier and the first information. If the first information indicates that the UE associated with UE1 (i.e., UE2) is paged (for example, the predefined bit / field / information in the paging-related message is a first value, and the first value is used to indicate that UE2 is paged), UE1 can notify UE2 that it is paged.

[0238] Optionally, in the manner of the first information being a predefined bit / field / information, after UE1 receives the paging-related message, UE1 can distinguish whether only itself is paged, only the associated UE is paged, or both itself and the associated UE are paged. In one manner, if the paging-related message indicates that both UE1 and the associated UE are paged, the paging-related message can carry two pieces of identification information of UE1, one of which has corresponding first information. In another manner, the identification information of UE1 can be carried once, and the first information can indicate whether only the associated UE is paged or both UE1 and the associated UE are paged. If the first information does not exist, it indicates that only UE1 is paged.

[0239] As another example, the access network device can also send an RRC message to UE1.

[0240] In this manner, the first container in the RRC message can be understood as the first information, and the paging message for paging UE2 can be sent by the core network device to the access network device or generated by the access network device. After UE1 receives the RRC message, UE1 needs to further analyze the paging message and check the identification information of UE2. If the identification information of UE2 is included in the paging message, UE1 can notify UE2 that it is paged.

[0241] Alternatively, the access network device can also carry the identification of UE2 or a predefined bit / field in the RRC message, and the predefined bit / field is used to indicate whether UE2 is paged. In this manner, the identification of UE2 or the predefined bit / field can be understood as the first information. After UE1 receives the RRC message and analyzes the first information, UE1 can determine that the UE associated with UE1 (i.e., UE2) is paged according to the first information, and UE1 can notify UE2 that it is paged.

[0242] In the present application, by associating UE1 and UE2, UE2 can receive the paging message through UE1, that is, UE1 detects the paging-related message of UE1 and UE2 on the PO of UE1, and UE2 does not need to wake up to detect the paging-related message of UE2 on the PO of UE2. Compared with the manner in which UE1 and UE2 both need to perform PO detection and paging message decoding, the present application can avoid the power consumption caused by UE2 receiving the paging message itself, and thus the present application can reduce the power consumption of the terminal device, improve the standby time of the multi-user identity terminal device, and further improve the user experience.

[0243] Another paging method is introduced below. The method adjusts the positions of the POs of one or more user identities so that the positions of the POs of at least two user identities completely overlap or partially overlap, thereby enabling the use of one set of hardware to receive paging messages of multiple user identities, thereby avoiding multiple passes of paging reception using multiple sets of hardware or multiple passes of paging using one set of hardware, thereby reducing the power consumption of terminal devices, improving the standby time of dual-card terminal devices, and further improving user experience.

[0244] As shown in FIG. 4, a flowchart of another paging method provided by an embodiment of the application is shown. The method includes the following steps.

[0245] S401, UE1 determines first information.

[0246] The first information is used to adjust the position of the PO of UE1.

[0247] The first information can be used for PO alignment or PO collision avoidance. For example, the first information can include one or more expected / suggested offset values that can be used when calculating the PO position. For example, the offset value can be an offset value of terminal device identification information, so that the PO can be determined based on the terminal device identification information after the offset value is calculated. For example, 5G-S-TMSI includes AMF SetID, AMF Pointer, and the result of 5G-TMSI+ offset value, i.e., <5G-S-TMSI> = <AMF Set ID><AMF Pointer><5G-TMSI+ offset value>. In this way, the value of 5G-S-TMSI adjusted by the offset value can adjust the PO position.

[0248] Alternatively, the first information can include one or more expected / suggested terminal device identification information (such as 5G-S-TMSI or 5G globally unique temporary UE identity (5G-GUTI)).

[0249] Alternatively, the first information can also include the value of one or more terminal device identification information (such as 5G-S-TMSI) mod 1024, where mod is the modulo operation. The core network device can calculate and assign 5G-S-TMSI for UE1, and only the value of the corresponding 5G-S-TMSI mod 1024 is required.

[0250] Alternatively, the first information can also include the position of one or more expected paging occasions.

[0251] By adjusting the position of the PO of UE1 through the first information, the position of the PO of UE1 and the position of the PO of UE2 can be completely overlapped or partially overlapped, so that the terminal devices corresponding to the first user identity (i.e., UE1) and the second user identity (i.e., UE2) can implement the paging of the two user identities through one set of hardware by performing one paging.

[0252] Optionally, the first information can further include a cause value, and the cause value includes an indication of expected PO alignment or an indication of avoiding PO collision.

[0253] At S402, UE1 sends the first information to the core network device. Correspondingly, the core network device receives the first information from UE1.

[0254] In a possible implementation, UE1 can send the first information to the core network device through a NAS message.

[0255] Optionally, the core network device can send a feedback confirmation to UE1, and the feedback confirmation is used to confirm / allow the adjustment of the position of the PO.

[0256] The feedback confirmation can further carry accepted adjustment information. For example, if the first information includes one or more expected / suggested offset values, the feedback confirmation can carry accepted offset values, and the accepted offset values are used to calculate the position of the PO, for example, <5G-S-TMSI> = <AMF Set ID><AMF Pointer><5G-TMSI + accepted offset value>. If the first information includes one or more expected / suggested terminal device identity information, the feedback confirmation can carry accepted terminal device identity information, and the accepted terminal device identity information is used to calculate the position of the PO. If the first information includes one or more values of terminal device identity information (such as 5G-S-TMSI) mod 1024, the feedback confirmation can carry accepted values of terminal device identity information (such as 5G-S-TMSI) mod 1024, and the accepted values of terminal device identity information (such as 5G-S-TMSI) mod 1024 are used to calculate the position of the PO.

[0257] Alternatively, the feedback acknowledgement can also not carry the accepted adjustment information, which can be understood as applying / receiving one or more offset values, or one or more terminal device identification information, or one or more positions of the paging occasions expected / suggested by the first information. For example, if the first information includes one or more offset values expected / suggested, the position of the PO can be calculated by applying the offset values indicated by the first information, for example, <5G-S-TMSI> = <AMF Set ID><AMF Pointer><5G-TMSI + expected / suggested offset value>. If the first information includes one or more terminal device identification information expected / suggested, the position of the PO can be calculated by applying the terminal device identification information. If the first information includes one or more values of terminal device identification information (such as 5G-S-TMSI) mod 1024 expected / suggested, the position of the PO can be calculated by applying the values of the terminal device identification information (such as 5G-S-TMSI) mod 1024.

[0258] Optionally, the feedback acknowledgement can also indicate that the core network device does not confirm / allow adjustment of the PO position, for example, the feedback acknowledgement can indicate that the core network device does not confirm / allow adjustment of the PO position by not carrying accepted adjustment information or carrying information indicating rejection.

[0259] Optionally, UE1 can also send second information to the core network device, the second information being used to indicate cancellation / withdrawal of one or more pieces of previously expected / suggested information, for example, cancellation / withdrawal of one or more previously expected / suggested offset values, cancellation / withdrawal of one or more previously expected / suggested terminal device identification information, or cancellation / withdrawal of one or more values of previously expected / suggested terminal device identification information mod 1024.

[0260] The core network device can send a NAS message to UE1 for feedback acknowledgement, which is used to confirm / allow cancellation / withdrawal of one or more previously expected / suggested offset values.

[0261] S403, the core network device sends third information to the access network device. Correspondingly, the access network device receives the third information.

[0262] The third information is used to indicate the paging occasion information of UE1, and the third information is determined according to the first information, which can be determined according to the adjustment information accepted by the core network device (such as accepted offset values, terminal device identification information, values of terminal device identification information mod 1024, etc.), or can be determined according to the adjustment information expected / suggested by UE1 (such as expected / suggested offset values, terminal device identification information, values of terminal device identification information mod 1024, etc.).

[0263] For example, the third information can include the identification information corresponding to UE1 or the remainder of the identification information corresponding to UE1 divided by 1024. For example, if the accepted adjustment information is an offset value, the identification information corresponding to UE1 is the identification information determined according to the accepted offset value or the expected / suggested offset value.

[0264] In a possible implementation, the core network device can send the third information when sending the paging message of UE1 to the access network device, for example, the third information can be included in the paging message. Optionally, this method can be applied in the scenario where UE1 is in an idle state.

[0265] In another possible implementation, the core network device sends the third information when sending the RRC INACTIVE core network assistance information of UE1 to the access network device, for example, the third information can be included in the RRC INACTIVE core network assistance information. Optionally, this method can be applied in the scenario where UE1 is in an inactive state.

[0266] S404, the access network device can send the paging-related message of UE1 on the PO indicated by the third information.

[0267] When the access network device receives the third information, the PO position of UE1 can be calculated according to the third information, and the paging-related message of UE1 is sent on the PO.

[0268] The method adjusts the position of the PO of one or more user identities, so that the PO positions of at least two user identities completely overlap or partially overlap, so that the terminal device can detect the paging-related messages of multiple user identities on a group of POs, thereby enabling the use of a set of hardware to receive paging messages of multiple user identities, thereby avoiding multiple passes of paging reception using multiple sets of hardware, or multiple passes of paging using a set of hardware, reducing the power consumption of the terminal device, improving the standby time of the dual-card terminal device, and thus improving the user experience.

[0269] Based on the same inventive concept as the method embodiment, the embodiments of the present application provide a communication apparatus, the structure of which can be as shown in FIG. 5, including a communication unit 501 and a processing unit 502.

[0270] In an embodiment, the communication apparatus can be specifically configured to implement the method performed by UE1 in the embodiment of FIG. 3. The apparatus can be UE1 itself, or a chip or chip set or a part of a chip in UE1 configured to perform the functions of the method. The processing unit 502 is configured to send, by the first user identity, a first message to a core network device through the communication unit 501, the first message being used to request / instruct the first user identity to receive a paging message corresponding to a second user identity; and receive, by the first user identity, first information from an access network device through the communication unit 501, the first information being used to instruct that the second user identity is paged.

[0271] Optionally, the processing unit 502 is further configured to send, by the first user identity, third information to the core network device through the communication unit 501, the third information being used to instruct to update an association relationship of the first user identity, or the third information being used to instruct that the first user identity has an association relationship.

[0272] In an embodiment, the communication apparatus can be specifically configured to implement the method performed by UE1 in the embodiment of FIG. 3.
