In a possible implementation, the communication system 100 may include multiple network devices 110, and each network device 110 may include other number of terminal devices 120 within its coverage area, which is not limited in this embodiment of the present application. In a possible implementation, the communication system 100 may also include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), which is not limited in this embodiment of the present application. Among them, the network device may include an access network device and a core network device. That is, the wireless communication system also includes multiple core networks for communicating with the access network device. The access network equipment may be an evolutionary base station (evolutional node B, which may be referred to as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), micro base station, access point (AP), transmission point (TP) or new generation Node B (gNodeB) in a long-term evolution (LTE) system, a next-generation (mobile communication system) (next radio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system. It should be understood that the equipment with communication functions in the network / system in the embodiment of the present application may be referred to as communication equipment. Taking the communication system shown in Figure 1 as an example, the communication equipment may include network equipment and terminal equipment with communication functions. The network equipment and terminal equipment may be specific equipment in the embodiment of the present application, which will not be repeated here; the communication equipment may also include other equipment in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited in the embodiment of the present application.

[0057] To facilitate understanding of the embodiments of the present application, the following briefly describes the basic processes and basic concepts involved in the embodiments of the present application. It should be understood that the basic processes and basic concepts introduced below do not limit the embodiments of the present application.

[0058] The 5G network system architecture is shown in Figure 2, which includes: NSSF (Network Slice Selection Function) is mainly used to manage network slice related information, such as selecting network slices for terminal devices; AUSF (Authentication Server Function) is used to complete the identity authentication function of user access; UDM (Unified Data Management) is used to manage and store contract data and authentication data; AMF (Access and Mobility Management Function) is used to complete mobility management, security anchor and secure UE policy management, etc. In addition to managing the mobility of UE, AMF is also responsible for forwarding session management related messages between UE and SMF; SMF (Session Management Function) is used to complete session management, UE IP address allocation and management, etc.; PCF (Policy Control Function) is responsible for formulating policies related to UE mobility management, session management, billing, etc.; AF (Application Function) is used for external application servers; UPF (User Plane Function) is used to manage and store user data and authentication data; The 5GC (5G Core Network) is a 5G core network that is used for complex user plane processing, such as forwarding traffic between the radio access network and the Internet, reporting traffic usage, and implementing QoS (Quality of Service) policies. The DN (Data Network) is the external data network of the 5GC (such as the Internet). Data is transmitted between the various nodes of the 5GC (5G Core Network), between the user equipment (UE) and the 5GC nodes, between the UE and the Radio Access Network (RAN), and between the RAN and the 5GC nodes through corresponding interfaces. For example, as shown in Figure 2: Data is transmitted between the AMF and NSSF in the 5GC through interface N22; the AMF transmits data to the SMF through interface N11; the AMF transmits data to the AUSF through N12; and the AMF transmits data to the UDM through interface N8. Data is transmitted between the SMF and the UPF through interface N4. The UPF transmits data to the external data network through interface N6 and to the AN through interface N3. The UE establishes an access layer connection with the AN through the Uu port, exchanges access layer messages and wireless data transmission, and establishes a non-access layer (NAS) connection with the AMF through the N1 port, exchanges NAS messages.Data is transmitted between the RAN and AMF via the N2 interface, and between the RAN and UPF via the N3 interface. It should be understood that the above description only describes the interfaces between some nodes, and the other interfaces between other 5GC nodes in Figure 2 are not described one by one.

[0059] UE policies in related technologies may include ANDSP (Access Network Discovery and Selection Policy), URSP (UE RoutE Selection Policy), and other policies. Among them, the ANDSP policy may include WLANSP (WLAN Selection Policy) and ePDG (Evolved Packet Data Gateway) / N3IWF (Non-3GPP InterWorking Function) network element selection information (optional).

[0060] Take the WLANSP policy as an example:

[0061] The WLANSP may include rule 1, which includes:

[0062] -Priority 1

[0063] -Validity Conditions (PLMN 1) (Validity Conditions (Public Land Mobile Network (PLMN) 1));

[0064] -Group of Selection Criteria with priority 1: (Group of selection criteria with priority 1):

[0065] -PreferredSSIDList=Priority 1:myoperator1, Priority 2:myoperator2 (Priority Service Set Identifier (SSID) list=Priority 1:myoperator1, Priority 2:myoperator2);

[0066] MinimumBackhaulThreshold = 2 Mbps in the downlink (Minimum backhaul threshold = 2 megabits per second in the downlink);

[0067] -Group of Selection Criteria with priority 2 (Group of selection criteria with priority 2):

[0068] -PreferredSSIDList=Priority 1:myoperator3.

[0069] The WLANSP may include rule 2, which includes:

[0070] -Priority 2

[0071] -Validity Conditions (PLMN 1) (Validity Conditions (Public Land Mobile Network (PLMN) 1));

[0072] -Group of Selection Criteria with priority 1: (Group of selection criteria with priority 1):

[0073] -PreferredRoamingPartnerList = Priority 1:partner1.com, Priority 2:partner2.com;

[0074] -MaximumBSSLoad (maximum BSS load) = 60.

[0075] As shown in Table 1 below, the Traffic Descriptor in the URSP is used to describe a specific service. For example, a microblog service can be described using the range of IP@1 to 9; another example is an IMS (IP Multimedia Subsystem) service that can be described using the DNN (Data Network Name) in the URSP. As shown in Table 2 below, a service descriptor can contain one or more Route Selection Descriptors (RSDs), each of which corresponds to the attributes of a PDU session (e.g., at least one of the following: route selection descriptor priority, route selection component, SSC (service and session continuity) mode selection, network slice selection, DNN selection, PDU session type selection, non-seamless offload indication, access type priority, route selection verification criteria, time window, location criteria, etc., as shown in Table 2). This means that the service data corresponding to the service descriptor can run in the PDU session corresponding to the RSD.

[0076] Table 1

[0077] Table 2

[0078] UE policy is implemented through the UCU (UE Configuration Update) process defined by 3GPP. As shown in Figure 3, the PCF puts the policy to be updated in a container and sends it to the AMF. The AMF forwards it directly to the UE using a NAS message. Specifically:

[0079] Steps 300-301: When the PCF on the network side decides to update the UE policy (PCF decides to update UE Policy), it puts the UE policy in a container and sends it to AMF. The container where the UE policy is located can be sent from PCF to AMF through the N1 and N2 interface communication message transmission message (Namf_Communication_N1N2MessageTransfer).

[0080] If the UE is in idle state, the AMF needs to first initiate step 302 Network Triggered Service Request to put the UE in connected state, and then execute step 303.

[0081] Step 303: The AMF transmits the UE policy (Delivery of UE policies) to the UE. Specifically, the AMF uses a downlink NAS message to transparently transmit the container carrying the UE policy to the UE.

[0082] Steps 304-305: After receiving the UE policy, the UE replies to the network with the result (Result of the delivery of UE policies) (e.g., indicating whether the transmission is successful). The AMF then transparently transmits the transmission result to the PCF through the N1 interface notification message (Namf_N1MessageNotify). The transmission result is transmitted through the container, and the AMF performs transparent transmission.

[0083] The UE associates the application with the corresponding PDU session for transmission based on the URSP policy. The mechanism is as follows:

[0084] When data appears at the application layer, the UE uses the URSP rules in the URSP policy to check whether the characteristics of the application data match the Traffic Descriptor of a rule in the URSP rule. The order of checking is determined by the Precedence (priority) in the Traffic Descriptor in the URSP rule. That is, the UE checks the matching status in order based on the priority. When a URSP rule is matched, the RSD list under the URSP rule is used to bind the PDU session.

[0085] When a URSP rule is matched, the UE searches for a suitable PDU session in the order of Precedence in the RSD. Here, the RSD with a high priority is used first. If a parameter in the RSD has one or more values, the UE selects one of them and combines it with other parameters to find out whether the PDU session exists. If it exists, the application data is bound to the session for transmission; if it does not exist, the UE triggers the establishment of the PDU session and establishes the attribute parameters of the PDU session reported by the UE in the request message. If the session is successfully established, the UE binds the application data to the session for transmission; if the session is not successfully established, the UE searches again for the existence of the PDU session based on other parameter combinations in the RSD or using parameter combinations in RSDs with lower priority.

[0086] If no suitable PDU session can be found for binding according to the matching URSP rule, the UE searches the TrafficDescriptor in the next priority URSP rule according to the Precedence order to see if it matches the application data flow characteristics. If so, the previously described process is repeated.

[0087] The above process of finding a suitable PDU session for the application is called "evaluation". After finding a suitable PDU session binding, the UE will re-execute the evaluation to check whether the binding relationship between the original application data and the PDU drawing needs to be changed in the following situations: the URSP is updated by the PCF; the UE moves from EPC to 5GC; change of Allowed NSSAI or Configured NSSAI; change of LADN DNN availability; UE registers over 3GPP or non-3GPP access; UE establishes connection to a WLAN access.

[0088] The QoS mechanism in the network architecture of the relevant protocols is as follows: The core network element (SMF) determines PCC rules based on policy information, subscription information, and local configuration. Based on the PCC rules, it generates QoS rules, PDRs (Packet Detection Rules), and QoS parameters. QoS rules are used by the UE to bind uplink service data flows to QoS flows, while PDRs are used by the UPF to bind downlink service data flows to QoS flows. QoS parameters are used to generate each QoS flow. The QoS parameters are sent to the RAN to generate the corresponding DRB for the QoS flow, ensuring end-to-end transmission quality (both on the air interface and the core network). For example, in uplink transmission, the UE receives data packets from the application, maps the uplink data packets to QoS flows based on QoS rules, and applies a QoS flow marking. The UE then marks all packets in the QoS flow with the same QFI, maps the QoS flow to AN resources, and sends it to the AN. The RAN (i.e., the AN shown in Figure 4) converts the QoS flows mapped to AN resources (i.e., the AN resources corresponding to each QoS flow generated by the AN based on QoS parameters) into PDU sessions, which are then sent to the UPF. In downlink transmission, the PDF side receives data packets from the application, classifies the data packets based on the PDR for QoS flow marking and other operations, marks all data packets in the QoS flow with the same QFI, combines the QoS flow into a PDU session, and sends the PDU session to the RAN (i.e., the AN shown in Figure 4). The RAN side transmits the received PDU (Protocol Data Unit) session to the UE side through AN resources.

[0089] With the development and popularization of electronic devices, there are now many different types of terminals available for consumer use, each with its own advantages. For example, as shown in Figure 5, users can own multiple electronic devices simultaneously, but different electronic devices may have different advantages and disadvantages. For example, in Figure 5, a mobile phone is a frequently used device. Its advantages include convenient input, powerful computing power, rich functions (including communication, multimedia, positioning, etc.), extremely high user stickiness, massive storage capacity, and high privacy. However, its disadvantages are a small screen, heavy weight and size, and heavy workload. Smart screens have advantages such as high-definition resolution, large screen, fixed location, remote control interaction, and public devices. However, their disadvantages are immobility, inconvenient interaction, and insufficient privacy. Watches have the advantages of being convenient, wearable, portable, small screen, good touch, physiological data detection, and private devices. However, their disadvantages are that they are not suitable for complex interactions and content. Tablets have the advantages of good touch and large screen size, but their disadvantages are large size and weight, making them difficult to carry around. AR / VR has the advantages of good display and high privacy, but their disadvantages are low computing power and unstable wearing comfort. Current UE policies are all based on UE ID (IMSI or SUPI). However, even if a terminal (UE) has the same UE ID, it may be used by different users (User ID) at different times. Different users have different network requirements due to reasons such as service preferences. The current 3GPP network cannot distinguish this function. In addition, the same user may use different electronic devices in different occasions. However, how to enable the same service to be freely switched between different terminals, and how to achieve multi-terminal collaboration for specific users and / or specific services on different devices based on the needs of the scenario and by supporting communication, computing and business continuity requirements to provide the best service experience, have become problems that need to be solved.

[0104] The first terminal and the second terminal may be 3GPP terminals, ie, terminals that can access a 3GPP network to send and receive data. This embodiment does not exhaustively list or limit various possible types of the first terminal and the second terminal.

[0105] The other terminals involved in the embodiments of the present application are all relative concepts, that is, the other terminals are relative to the first terminal or the second terminal.

[0106] In some embodiments, the network devices serving the first terminal and the network devices serving the second terminal are the same, that is, the first network device and the second network device can be the same. In such embodiments, the first network device and the second network device may not be distinguished. For example, the first network device can serve the first terminal and the second terminal. In some embodiments, the network devices serving the first terminal and the network devices serving the second terminal are different, that is, the first network device and the second network device are different.

[0107] In some possible implementations, the network side (for example, a first network device serving the first terminal and the second terminal, or a second network device serving the second terminal) has allocated a UE policy corresponding to the second terminal. This implementation describes the relevant processing of the first terminal in this state.

[0114] The first network device sends the second information to the first terminal, which can be: the first network device carries the second information in a downlink UE policy container, triggering the UCU process to send the downlink UE policy container to the first terminal through the fourth network device. Correspondingly, the first terminal receives the second information sent by the first network device, including: the first terminal receives the downlink UE policy container carrying the second information sent by the first network device through the fourth network device in the UCU process. Here, the UCU process is a non-registered process.

[0115] Among them, the fourth network device also serves the first terminal. The fourth network device is different from the first network device. For example, the fourth network device can be an access and mobility management function (AMF) serving the first terminal.

[0122] The one or more specified policies may be predefined or negotiated.

[0124] The one or more specified parameters may be predefined or negotiated.

For example, the one or more specified policies include URSP and ANDSP, the one or more specified rules may be Rule-1 and Rule-2 under the URSP, and the one or more specified parameters may be Parameter a1 and Parameter a2 under Rule 1 under the URSP policy.

[0125] In some possible implementations, the UE policy related to the second terminal can be divided into UE policies in different dimensions.

The third network device includes at least one of the following: a unified data management function (UDM) or a unified data repository function (UDR).

[0128] In some embodiments, the first information includes a first identifier, wherein the first identifier includes at least one of the following: an identifier of the second terminal, an identifier of the first service, and an identifier of the first user.

SUCI is a privacy-preserving identifier that includes a hidden SUPI. The format supported by the PEI parameter is IMEI (International Mobile Station Equipment Identity).

[0130] The identifier of the first service may include at least one of the following: the name of the first service, the ID of the first service, the number of the first service, etc. It should be understood that the first service may also be replaced by the first application, and the identifier of the first service may also be replaced by the identifier of the first application. For example, the identifier of the first application may include: the name of the first application, the ID of the first application, the number of the first application, etc. For the sake of simplicity, this embodiment will be described below using only the first service as an example. All descriptions of the first service below may be replaced by the first application, but will not be repeated.

[0131] The identifier of the first user includes at least one of the following: an ID of the first user and biometric information of the first user.

The biometric information may refer to at least one of specific feature information of a fingerprint, specific feature information of a facial feature, or specific feature information of a voice feature, or the biometric information may refer to at least one of a fingerprint ID, a facial feature ID, or a voice feature ID.

[0132] In some embodiments, the first identifier includes only an identifier of the second terminal. The UE policy associated with the second terminal may include: at least a portion of the UE policy corresponding to the second terminal. The at least a portion of the UE policy corresponding to the second terminal may include: UE policies in the UE policy corresponding to the second terminal that can be assigned to terminals other than the second terminal.

[0133] In one example, the first network device locally obtaining the UE policy associated with the second terminal may include: upon determining, based on an identifier of the second terminal, that a UE policy corresponding to the second terminal is locally stored, the first network device obtaining, from the UE policy corresponding to the second terminal, a UE policy that can be assigned to terminals other than the second terminal, and using the UE policy that can be assigned to terminals other than the second terminal in the UE policy corresponding to the second terminal as the UE policy associated with the second terminal. In this example, the first network device may simultaneously serve the first terminal and the second terminal.

[0134] In one example, the first network device obtains the UE policy related to the second terminal from the second network device, which may include: when the first network device determines based on the identifier of the second terminal that the second network device stores the UE policy corresponding to the second terminal, the first network device obtains the UE policy that can be assigned to terminals other than the second terminal in the UE policy corresponding to the second terminal from the second network device, and uses the UE policy that can be assigned to terminals other than the second terminal in the UE policy corresponding to the second terminal as the UE policy related to the second terminal.

[0135] Here, the second network device may serve the second terminal; this embodiment does not limit the manner in which the first network device determines, based on the identifier of the second terminal, that the second network device stores the UE policy corresponding to the second terminal.

[0136] The first network device obtains the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal from the second network device, which may include one of the following: the first network device obtains the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal stored in the second network device; the first network device obtains the UE policy corresponding to the second terminal from the second network device, and extracts the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal.

[0137] In one example, the first network device obtains the UE policy related to the second terminal from the third network device, which may include: when the first network device determines based on the identifier of the second terminal that the UE policy corresponding to the second terminal is not locally stored, the first network device obtains the UE policy that can be assigned to other terminals other than the second terminal from the UE policy corresponding to the second terminal from the third network device, and uses the UE policy that can be assigned to other terminals other than the second terminal in the UE policy corresponding to the second terminal as the UE policy related to the second terminal. Here, the third network device can be used to store all UE policies for multiple terminals. This embodiment does not limit the manner in which the third network device obtains and saves all UE policies for each terminal.

[0138] The first network device obtains the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal from the third network device, which may include one of the following: the first network device obtains the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal stored in the third network device; the first network device obtains the UE policy corresponding to the second terminal from the third network device, and extracts the UE policy that can be allocated to terminals other than the second terminal from the UE policy corresponding to the second terminal.

[0139] In some embodiments, the first identifier includes only an identifier of the first service. The UE policy associated with the second terminal includes: at least a portion of the UE policy corresponding to the first service run by the second terminal. Optionally, the at least a portion of the UE policy corresponding to the first service run by the second terminal may include: a UE policy corresponding to the first service run by the second terminal that can be allocated to other terminals other than the second terminal.

[0140] In one example, the first network device obtains the UE policy related to the second terminal from the local area, which may include: based on the identifier of the first service, the first network device determines that there is a second terminal running the first service locally and has a binding relationship with the first terminal, and obtains the UE policy corresponding to the first service run by the second terminal that can be assigned to terminals other than the second terminal, and uses the UE policy corresponding to the first service run by the second terminal that can be assigned to terminals other than the second terminal as the UE policy related to the second terminal.

[0141] The first network device, based on the identifier of the first service, determines whether there is a second terminal running the first service locally and having a binding relationship with the first terminal. The processing may include: the first network device, based on the identifier of the first service, determines whether there are one or more other terminals running the first service locally and having a binding relationship with the first terminal. If so, one of the one or more other terminals running the first service and having a binding relationship with the first terminal is used as the second terminal. The one or more other terminals having a binding relationship with the first terminal may be pre-stored in the first network device. This embodiment does not limit the manner in which the first network device obtains or obtains the binding relationship between the first terminal and the one or more other terminals. The binding relationship can also be alternatively described as an association relationship, a correlation, etc. This embodiment does not exhaustively enumerate and limit all possible descriptions of the binding relationship. It should be noted that the one or more other terminals refer to other terminals different from the first terminal.

[0142] There are two situations in which one of the one or more other terminals that run the first service and have a binding relationship with the first terminal is used as the second terminal: in one situation, there is only one other terminal that runs the first service and has a binding relationship with the first terminal, and the other terminal is directly used as the second terminal. In another situation, there are multiple other terminals that run the first service and have a binding relationship with the first terminal. In this case, other terminals that meet the first preset condition can be selected from the multiple other terminals as the second terminal. The first preset condition may include at least one of the following: the UE policy corresponding to the designated terminal and the first service is recently or newly generated. The designated terminal may be pre-configured or default, for example, the designated terminal may be a smartphone, or the designated terminal may be a laptop, etc. All possible types of designated terminals are not exhaustively listed here.

[0143] In one example, the first network device obtains the UE policy related to the second terminal from the second network device, which may include: the first network device obtains, from the second network device based on the identifier of the first service, the UE policy corresponding to the first service run by the second terminal and that can be allocated to terminals other than the second terminal, and uses the UE policy corresponding to the first service run by the second terminal and that can be allocated to terminals other than the second terminal as the UE policy related to the second terminal.

[0144] Here, the second network device may be serving the second terminal. The manner in which the first network device determines the second network device may include: the first network device determines whether there are one or more other terminals running the first service and having a binding relationship with the first terminal locally based on the identifier of the first service; if not, the first network device uses one of the one or more other terminals running the first service and having a binding relationship with the first terminal as the second terminal, and determines the network device corresponding to the second terminal as the second network device. The processing of the first network device using one of the one or more other terminals running the first service and having a binding relationship with the first terminal as the second terminal is the same as in the aforementioned embodiment and will not be elaborated on.

[0145] Among them, the first network device obtains the UE policy corresponding to the first service run by the second terminal from the second network device and can be allocated to other terminals except the second terminal, which may include one of the following: the first network device obtains the UE policy corresponding to the second terminal from the second network device, and extracts the UE policy corresponding to the first service run by the second terminal and can be allocated to other terminals except the second terminal from the UE policy corresponding to the second terminal; the first network device extracts the UE policy corresponding to the first service run by the second terminal and can be allocated to other terminals except the second terminal from the UE policy corresponding to the second terminal saved by the second network device.

[0146] In one example, the first network device obtains the UE policy related to the second terminal from the third network device, which may include: the first network device obtains, from the third network device based on the identifier of the first service, the UE policy corresponding to the first service run by the second terminal and that can be allocated to terminals other than the second terminal, and uses the UE policy corresponding to the first service run by the second terminal and that can be allocated to terminals other than the second terminal as the UE policy related to the second terminal.

[0147] Among them, the first network device obtains the UE policy corresponding to the first service run by the second terminal and can be allocated to other terminals except the second terminal from the third network device, which may include one of the following: the first network device obtains the UE policy corresponding to the second terminal from the third network device, and extracts the UE policy corresponding to the first service run by the second terminal and can be allocated to other terminals except the second terminal from the UE policy corresponding to the second terminal; the first network device extracts the UE policy corresponding to the first service run by the second terminal and can be allocated to other terminals except the second terminal from the UE policy corresponding to the second terminal saved by the third network device.

[0148] Here, since the third network device can be used to store UE policies of different terminals generated by each PCF, when the first network device determines that the UE policy of the second terminal is not stored locally, the UE policy related to the second terminal can be directly obtained from the third network device.

[0149] In one embodiment, the first identifier includes only the identifier of the first user. The UE policies associated with the second terminal include: at least some UE policies corresponding to the first user using the second terminal. Optionally, the at least some UE policies corresponding to the first user using the second terminal may include: UE policies corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal.

[0150] In one example, the first network device obtains the UE policy related to the second terminal from the local area, which may include: based on the identifier of the first user, the first network device determines that there is a second terminal used by the first user and has a binding relationship with the first terminal locally, and then obtains the UE policy corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal from the UE policy corresponding to the second terminal stored locally, and uses the UE policy corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal as the UE policy related to the second terminal.

[0151] The first network device, based on the identifier of the first user, determines whether there is a second terminal locally that is used by the first user and has a binding relationship with the first terminal. This may include: the first network device, based on the identifier of the first user, determines whether there are one or more other terminals locally that are used by the first user and have a binding relationship with the first terminal; if so, one of the one or more other terminals used by the first user and have a binding relationship with the first terminal is used as the second terminal. Here, the description of the one or more other terminals having a binding relationship with the first terminal is the same as that in the previous embodiment and is not repeated here.

[0152] There are two situations in which one of the one or more other terminals used by the first user and having a binding relationship with the first terminal is used as the second terminal: In one situation, there is only one other terminal used by the first user and having a binding relationship with the first terminal, and the other terminal is directly used as the second terminal. In another situation, there are multiple other terminals used by the first user and having a binding relationship with the first terminal. In this case, other terminals that meet the second preset condition can be selected from the multiple other terminals as the second terminal. The second preset condition may include at least one of the following: the UE policy corresponding to the designated terminal and the first user is recently or newly generated. The definition of the designated terminal is the same as that in the previous embodiment and is not repeated here.

[0153] In one example, the first network device obtains the UE policy related to the second terminal from the second network device, which may include: the first network device obtains, from the second network device based on the identifier of the first user, the UE policy corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal, and uses the UE policy corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal as the UE policy related to the second terminal.

[0154] Here, the method for the first network device to determine the second network device may include: the first network device determines whether there are one or more other terminals used by the first user and having a binding relationship with the first terminal locally based on the identifier of the first user; if not, then the first network device determines in turn whether there are one or more other terminals used by the first user and having a binding relationship with the first terminal on each candidate network device; if so, then one of the one or more other terminals used by the first user and having a binding relationship with the first terminal is used as the second terminal, and the network device corresponding to the second terminal is determined as the second network device. The method for the first network device to process one of the one or more other terminals running the first service and having a binding relationship with the first terminal as the second terminal is the same as in the aforementioned embodiment and will not be repeated.

[0155] The first network device obtains from the second network device the UE policy corresponding to the first user using the second terminal, which can be assigned to terminals other than the second terminal, and may include one of the following: the first network device obtains from the second network device the UE policy corresponding to the second terminal, and extracts from the UE policy corresponding to the second terminal the UE policy corresponding to the first user using the second terminal, which can be assigned to terminals other than the second terminal; the first network device extracts from the UE policy corresponding to the second terminal stored by the second network device, the UE policy corresponding to the first user using the second terminal, which can be assigned to terminals other than the second terminal.

[0157] Among them, the first network device obtains the UE policy corresponding to the first user using the second terminal from the third network device, which can be assigned to terminals other than the second terminal, and may include one of the following: the first network device obtains the UE policy corresponding to the second terminal from the third network device, and extracts the UE policy corresponding to the first user using the second terminal, which can be assigned to terminals other than the second terminal, from the UE policy corresponding to the second terminal; the first network device extracts the UE policy corresponding to the first user using the second terminal, which can be assigned to terminals other than the second terminal, from the UE policy corresponding to the second terminal stored by the third network device.

[0158] In some embodiments, the first identifier includes an identifier of the second terminal, and the first identifier further includes at least one of the following: an identifier of the first service, an identifier of the first user.

[0159] Optionally, the first identifier may include the identifier of the second terminal and the identifier of the first service, that is, the first identifier is used to indicate the first service run by the second terminal; accordingly, the UE policy related to the second terminal includes the UE policy corresponding to the first service run by the second terminal that can be allocated to other terminals other than the second terminal.

[0160] Optionally, the first identifier may include the identifier of the second terminal and the identifier of the first user, that is, the first identifier is used to indicate the first user using the second terminal; accordingly, the UE policy related to the second terminal includes the UE policy corresponding to the first user using the second terminal that can be assigned to other terminals other than the second terminal.

Accordingly, the UE policy related to the second terminal includes a UE policy corresponding to the first service running under the first user using the second terminal that can be assigned to other terminals other than the second terminal.

[0162] The above provides the possible contents of the UE policy related to the second terminal under different combinations of the first identifiers. In the examples provided below, the contents of the UE policy related to the second terminal under different combinations of the first identifiers will not be repeated.

[0163] In one example, the first network device obtains the UE policy related to the second terminal locally, which may include: when the first network device determines that the UE policy corresponding to the second terminal is stored locally based on the identifier of the second terminal contained in the first identifier, the first network device obtains the locally stored UE policy related to the second terminal based on at least one of the identifier of the first service and the identifier of the first user contained in the first identifier.

[0166] The first network device obtains the UE policy related to the second terminal from the second network device based on at least one of the identifier of the first service and the identifier of the first user contained in the first identifier, which may include one of the following: after the first network device obtains the UE policy corresponding to the second terminal from the second network device, the first network device selects the UE policy related to the second terminal from the UE policy corresponding to the second terminal based on at least one of the identifier of the first service and the identifier of the first user; or, the first network device directly obtains the UE policy corresponding to the second terminal from the second network device based on at least one of the identifier of the first service and the identifier of the first user, and extracts the UE policy related to the second terminal.

[0167] In one example, the first network device obtains the UE policy related to the second terminal from the third network device, which may include: when the first network device determines that the UE policy corresponding to the second terminal is not stored locally based on the identifier of the second terminal included in the first identifier, the first network device obtains the UE policy related to the second terminal from the third network device based on at least one of the identifier of the first service and the identifier of the first user.

[0168] Regarding the first network device obtaining the UE policy related to the second terminal from the third network device based on at least one of the identifier of the first service and the identifier of the first user, it may include one of the following: after the first network device obtains the UE policy corresponding to the second terminal from the third network device, the first network device selects the UE policy related to the second terminal from the UE policies corresponding to the second terminal based on at least one of the identifier of the first service and the identifier of the first user; or, the first network device directly obtains the UE policy related to the second terminal from the third network device based on at least one of the identifier of the first service and the identifier of the first user.

[0169] In some possible embodiments, the first information does not include the first identifier.

[0170] In this embodiment, the UE policy related to the second terminal may include: UE policies corresponding to the second terminal that can be allocated to other terminals except the second terminal.

[0171] It should be noted that if the first network device pre-configures or defaults at least one of the identifier of the first service and the identifier of the first user, the UE policy associated with the second terminal may also include at least one of the following: a UE policy corresponding to the first service run by the second terminal that can be assigned to terminals other than the second terminal; a UE policy corresponding to the first user using the second terminal that can be assigned to terminals other than the second terminal. For example, the aforementioned first service can be a designated service pre-configured on the first network device. In this case, the first network device may default to obtaining the UE policy corresponding to the first service run by the second terminal that can be assigned to terminals other than the second terminal as the UE policy associated with the second terminal. All possible situations are not enumerated here.

[0172] For the sake of convenience, the following example illustrates an exemplary embodiment in which the UE policy related to the second terminal includes a UE policy corresponding to the second terminal that can be allocated to other terminals other than the second terminal.

[0173] In one example, the first network device obtains the UE policy related to the second terminal from the local area, which may include: when the first network device determines that there is a second terminal having a binding relationship with the first terminal locally, the first network device obtains the UE policy corresponding to the second terminal stored in itself, which can be allocated to other terminals except the second terminal, as the UE policy related to the second terminal.

[0174] The first network device determines whether there is a second terminal that has a binding relationship with the first terminal locally, which may include: the first network device determines whether there are one or more other terminals that have a binding relationship with the first terminal locally, and if so, uses one of the one or more other terminals that have a binding relationship with the first terminal as the second terminal.

[0175] Here, one of the one or more other terminals that have a binding relationship with the first terminal is used as the second terminal in two situations: in one situation, if there is only one other terminal that has a binding relationship with the first terminal, then the other terminal is directly used as the second terminal; in another situation, if there are multiple other terminals that have a binding relationship with the first terminal, then other terminals among the multiple other terminals that meet a third preset condition can be used as the second terminal. The third preset condition can include at least one of the following: the UE policy is the most recently or newly generated, designated terminal. The description of the designated terminal is the same as in the previous embodiment and is not repeated here.

[0176] In one example, the first network device obtains the UE policy related to the second terminal from the second network device, which may include: when the first network device determines that the second network device has a second terminal that has a binding relationship with the first terminal, the first network device obtains from the second network device the UE policy corresponding to the second terminal, the UE policy that can be allocated to terminals other than the second terminal, and uses the UE policy that can be allocated to terminals other than the second terminal as the UE policy related to the second terminal.

[0177] In this example, the method for the first network device to determine whether the second network device has a second terminal that has a binding relationship with the first terminal may include: the first network device determines whether there are one or more other terminals that have a binding relationship with the first terminal locally; if not, then sequentially determines whether each candidate network device has one or more other terminals that have a binding relationship with the first terminal; if so, then one of the one or more other terminals that have a binding relationship with the first terminal is used as the second terminal, and the network device corresponding to the second terminal is determined as the second network device. Here, the method for processing one of the one or more other terminals that have a binding relationship with the first terminal as the second terminal is the same as in the aforementioned embodiment and will not be repeated.

[0178] In one example, the first network device obtains the UE policy related to the second terminal from the third network device, which may include: the first network device obtains the UE policy corresponding to the second terminal that has a binding relationship with the first terminal from the third network device, and uses the UE policy corresponding to the second terminal that can be assigned to other terminals other than the second terminal as the UE policy related to the second terminal. Here, the method of determining the second terminal that has a binding relationship with the first terminal may be: when there is only one other terminal that has a binding relationship with the first terminal on the third network device, the other terminal is directly used as the second terminal; or, when there are multiple other terminals that have a binding relationship with the first terminal on the third network device, other terminals that meet the third preset condition among the multiple other terminals may be used as the second terminal. The description of the third preset condition is the same as that in the aforementioned embodiment and will not be repeated here.

[0179] In some possible embodiments, the UE policy of the first terminal includes at least one of the following: the first part of the UE policy in the UE policy related to the second terminal; and the UE policy related to the second part of the UE policy in the UE policy related to the second terminal.

[0180] In one embodiment, the UE policy of the first terminal includes a first portion of UE policies in the UE policy related to the second terminal. The first portion of UE policies may be all or part of the parameters of the UE policy related to the second terminal.

[0181] The first network device generates the UE policy of the first terminal based on the first part of the UE policy in the UE policy related to the second terminal, which may include: the first network device may add the first part of the UE policy in the UE policy related to the second terminal to the UE policy of the first terminal.

[0182] In some possible cases, the processing of the first network device may further include: the first network device generating other UE policies for the first terminal, and adding the other UE policies for the first terminal to the UE policy of the first terminal. The other UE policies for the first terminal may be generated based on local relevant configurations of the first network device and / or relevant parameters or relevant configurations of the first terminal. The other UE policies for the first terminal are different from and / or unrelated to any UE policy of the second terminal. The specific method for generating the other UE policies for the first terminal is not limited in this embodiment.

[0183] In one embodiment, the UE policy of the first terminal may include: a UE policy related to a second part of UE policies in the UE policy related to the second terminal.

[0184] The second part of the UE policy may be all or part of the UE policy related to the second terminal. The UE policy related to the second part of the UE policy in the UE policy related to the second terminal may be obtained after adjusting the second part of the UE policy in the UE policy related to the second terminal based on the mapping relationship and / or the association relationship.

[0185] The first network device generates the UE policy of the first terminal based on the UE policy related to the second terminal, which may include: the first network device processes the second part of the UE policy in the UE policy related to the second terminal to obtain the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal; the first network device generates the UE policy of the first terminal based on the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal.

[0186] The first network device processes the second part of the UE policy in the UE policy related to the second terminal to obtain the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal, which may include: the first network device adjusts the second part of the UE policy in the UE policy related to the second terminal according to the relevant information of the first terminal and a preset mapping relationship table (or association relationship table) to obtain the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal that is applicable to the first terminal.

[0187] The relevant information of the first terminal is different from the relevant information of the second terminal. For example, the relevant information of the first terminal may include at least one of the bitrate supported by the first terminal, the resolution supported by the first terminal, the computing capability supported by the first terminal, the communication capability of the first terminal, the display clarity of the first terminal, and the like. The relevant information of the first terminal may have been pre-acquired by the first network device, and the manner in which the first network device obtains the relevant information of the first terminal is not limited herein.

[0188] The mapping relationship table and / or association relationship table may be pre-configured or obtained through negotiation, and this embodiment does not limit this. In actual processing, as long as the relevant information of the first terminal and the second terminal is different, a corresponding adjustment method may exist, and the relevant parameters of the second part of the UE policy in the UE policy related to the second terminal after adjustment based on the mapping relationship table and / or association relationship table are applicable to the first terminal, which is within the scope of protection of this embodiment and is not exhaustive here.

[0189] The first network device generates the UE policy of the first terminal based on the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal, which may be: the first network device may add the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal to the UE policy of the first terminal. In some possible cases, the processing of the first network device may also include: the first network device generates other UE policies for the first terminal, and adds the other UE policies of the first terminal to the UE policy of the first terminal. The description of the other UE policies of the first terminal is the same as that in the aforementioned embodiment, and is not limited in this embodiment.

[0190] In this embodiment, the first network device adjusts the second part of the UE policy in the UE policy related to the second terminal by combining the relevant information of the first terminal and the mapping relationship table (or association relationship table), and can obtain the UE policy related to the second part of the UE policy in the UE policy related to the second terminal, and then generates the UE policy of the first terminal based on the UE policy related to the second part of the UE policy in the UE policy related to the second terminal, so that the UE policy of the first terminal is associated with the UE policy related to the second terminal while ensuring its applicability or higher applicability in the first terminal.

[0191] In one embodiment, the UE policy of the first terminal may include the following two parts: a first part of the UE policy in the UE policy related to the second terminal, and a UE policy related to the second part of the UE policy in the UE policy related to the second terminal. In this case, the first part of the UE policy is different from the second part of the UE policy, and the first part of the UE policy and the second part of the UE policy may constitute all or part of the UE policy related to the second terminal.

[0192] The first network device generates the UE policy of the first terminal based on the UE policy related to the second terminal, which may include: the first network device directly adds the first part of the UE policy in the UE policy related to the second terminal to the UE policy of the first terminal; and the first network device processes the second part of the UE policy in the UE policy related to the second terminal to obtain the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal, and adds the relevant UE policy of the second part of the UE policy in the UE policy related to the second terminal to the UE policy of the first terminal. The relevant explanations about the first network device's processing of the first part of the UE policy and the second part of the UE policy of the UE policy related to the second terminal are the same as those in the previous embodiment and will not be repeated.

[0193] After the above processing, the UE policy of the first terminal may include: the first part of the UE policy in the UE policy related to the second terminal, and / or the UE policy related to the second part of the UE policy in the UE policy related to the second terminal. For example, in conjunction with Figure 10, Figure 10 illustrates UE-1 and UE-2, and the UE-1 and UE-2 serve the same user A or the same application A. Assuming that UE-1 is the aforementioned first terminal and UE-2 is the aforementioned second terminal, the first network device has allocated UE policy-2 corresponding to user A (or application A) to UE-2. When user A (or application A) needs to be migrated from UE-2 to UE-1, user A can be allocated based on UE policy-2.

[0194] UE policy-1 corresponding to user A (or application A) is assigned to UE-1. UE policy-1 and UE policy-2 may be partially identical, partially different, and / or partially related, or UE policy-1 and UE policy-2 corresponding to user A (or application A) assigned to UE-1 may be completely identical. For example, if UE-1 and UE-2 serve the same user A, the second part of UE policy-2 assigned to UE-2 includes rule-1 under the URSP, while the UE policy-1 assigned to UE-1 includes rule-2 under the URSP. The association between the two may be based on pre-configuration or negotiation. For example, UE-1 and UE-2 serve the same application A. The second part of the UE policy in UE policy-2 assigned to UE-2 includes RSD parameter-1 of TD-1 in rule-1 under the URSP, while the UE policy-1 assigned to UE-1 includes RSD parameter-2 of TD-1 in rule-1 under the URSP. Furthermore, UE-1's UE policy-1 also includes the first part of UE policy in UE policy-2 of UE-2. For example, UE-1 and UE-2 use TD-2 in rule-1 under the same URSP. There are many reasons why UE-1 and UE-2 may have different UE policies, such as different computing capabilities, communication capabilities, and display resolutions, which may lead to differences in their UE policies.

[0195] It should also be noted with respect to Figure 10 that UE-1 and UE-2 are merely any two UEs serving the same user A or the same application A. In actual processing, there may be more UEs serving the same user A or the same application A. For example, in addition to UE-1 and UE-2, there may also be UE-3, UE-4, etc. that also serve the same user A or the same application A. Similar processing between UE-1 and UE-2 can be performed between any two UEs serving the same user A or the same application A. However, for the sake of simplicity in Figure 10, more UEs are not illustrated one by one.

[0196] In one embodiment, the second information further includes selection indication information, and the selection indication information is used to indicate at least one of the following: a UE policy used by the second terminal, and a UE policy preferentially selected by the first terminal.

[0197] In this embodiment, the process of the first network device generating the UE policy for the first terminal is the same as that in the above embodiment and will not be described repeatedly.

[0198] The method differs from the previous embodiment in that the first network device further includes: obtaining, by the first network device, a policy update indication for the second terminal, wherein the policy update indication is used to determine, within the UE policy of the second terminal, a UE policy used by the second terminal. Exemplarily, the policy update indication may include at least one of the following: content of the UE policy used by the second terminal, a name of the UE policy used by the second terminal, an identifier of the UE policy used by the second terminal, a number of the UE policy used by the second terminal, and relevant descriptive information about the UE policy used by the second terminal.

[0199] The UE policy used by the second terminal may include at least one of the following: a policy used by the second terminal in a UE policy corresponding to the second terminal; a rule used by the second terminal in a UE policy corresponding to the second terminal; or a parameter used by the second terminal in a UE policy corresponding to the second terminal. The policy used by the second terminal may include at least one of the following: URSP, V2X policy, ASSSS policy, ANDSP, WLANSP, and ProSe Policy.

[0200] The first network device obtaining the policy update indication of the second terminal may include one of the following: when the first network device serves the first terminal and the second terminal at the same time, the first network device directly receives the policy update indication of the second terminal; when the first network device serves the first terminal and the second network device serves the second terminal, the first network device obtains the policy update indication of the second terminal from the second network device.

[0201] The first network device directly receiving the policy update instruction of the second terminal may mean that the first network device can directly receive the policy update instruction of the second terminal at any time.

[0202] The first network device obtains the policy update indication of the second terminal from the second network device, which may refer to: before the first network device generates the UE policy of the first terminal, or before the first network device sends the second information, the first network device obtains the policy update indication of the second terminal from the second network device. Here, the first network device obtains the policy update indication of the second terminal from the second network device, which may include: the first network device queries the second network device whether there is a policy update indication of the second terminal; if not, the policy update indication of the second terminal is not obtained; if so, the policy update indication of the second terminal is obtained from the second network device. The timing of the first network device querying the second network device whether there is a policy update indication of the second terminal may be at the same time as the first network device obtains the UE policy related to the second terminal from the second network device, or before or after the first network device obtains the UE policy related to the second terminal from the second network device. As long as it is before the first network device sends the second information, it is within the protection scope of this embodiment.

[0203] Optionally, the processing of the first network device may also include: generating selection indication information based on relevant information of the UE policy used by the second terminal in the UE policy of the first terminal when the UE policy used by the second terminal exists in the UE policy of the first terminal; and / or, not generating selection indication information when the UE policy used by the second terminal does not exist in the UE policy of the first terminal.

[0204] In this case, the selection indication information can be used to indicate the UE policy used by the second terminal; specifically, the selection indication information is used to indicate the UE policy used by the second terminal in the UE policy of the first terminal. The selection indication information may include: the content of the UE policy used by the second terminal in the UE policy of the first terminal, the name of the UE policy used by the second terminal in the UE policy of the first terminal, the identifier of the UE policy used by the second terminal in the UE policy of the first terminal, the number of the UE policy used by the second terminal in the UE policy of the first terminal, relevant description information of the UE policy used by the second terminal in the UE policy of the first terminal, and the like.

[0205] Optionally, the processing of the first network device may also include: generating selection indication information based on relevant information of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, when there is a UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal; and / or, not generating selection indication information, when there is no UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal.

[0206] In this case, the selection indication information can be used to indicate the UE policy that the first terminal preferentially selects; specifically, the selection indication information is used to indicate the priority selection of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal. The selection indication information may include: the content of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, the name of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, the identifier of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, the number of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, relevant description information of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, and the like.

[0207] Optionally, the processing of the first network device may also include: when there is a UE policy used by the second terminal in the UE policy of the first terminal, and there is a UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal, generating selection indication information based on relevant information of the UE policy used by the second terminal in the UE policy of the first terminal, and based on relevant information of the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal.

[0208] In this case, the selection indication information can be used to indicate the UE policy used by the second terminal in the UE policy of the first terminal, and to indicate the UE policy related to the UE policy used by the second terminal in the UE policy of the first terminal. The selection indication information can include the content of the two examples above, which will not be repeated.

[0209] In this embodiment, the second information includes selection indication information, which may mean that the second information includes multiple information elements, the first information element carries the selection indication information, and the second information element carries the UE policy of the first terminal. The first information element and the second information element are different, and the first information element and the second information element are both any information elements among the multiple information elements of the second information.

[0210] Alternatively, the second information includes selection indication information, which may mean that the second information includes multiple information elements, and the first information element carries the selection indication information and the UE policy of the first terminal. The first information element is any one of the multiple information elements of the second information.

[0211] Alternatively, the selection indication information is used as a component of the UE policy of the first terminal; accordingly, the second information includes the selection indication information, which may mean: the second information includes multiple information elements, the first information element carries the UE policy of the first terminal, and the UE policy of the first terminal contains the selection indication information.

[0212] In one embodiment, the UE policy related to the second terminal may include: a related UE policy used by the second terminal and capable of being allocated to other terminals except the second terminal.

[0213] Specifically, at least part of the UE policies corresponding to the second terminal may include: UE policies used by the second terminal in the UE policies corresponding to the second terminal and that can be allocated to terminals other than the second terminal. At least part of the UE policies corresponding to the first service run by the second terminal may include: UE policies used by the first service run by the second terminal and that can be allocated to terminals other than the second terminal. At least part of the UE policies corresponding to the first user using the second terminal may include: UE policies used by the first user of the second terminal and that can be allocated to terminals other than the second terminal.

[0214] When executing the process of this embodiment, the first network device needs to obtain the policy update indication of the second terminal before generating the UE policy of the first terminal. The first network device obtains the policy update indication of the second terminal and the relevant description of the policy update indication has been detailed and will not be repeated here.

[0215] In one embodiment, after the first network device receives the first information, the method further includes: the first network device obtains the UE policy related to the second terminal based on the policy update indication of the second terminal; and the first network device generates the UE policy of the first terminal based on the UE policy related to the second terminal.

[0216] The first network device obtains the UE policy related to the second terminal based on the policy update indication of the second terminal, which may include one of the following: the first network device obtains the UE policy related to the second terminal from the local based on the policy update indication of the second terminal; the first network device obtains the UE policy related to the second terminal from the second network device based on the policy update indication of the second terminal, and the second network device serves the second terminal.

[0217] In some embodiments, the first identifier only includes an identifier of the second terminal. In this embodiment, the UE policy related to the second terminal may include: a UE policy corresponding to the second terminal, used by the second terminal, and capable of being allocated to other terminals except the second terminal.

[0218] In one example, the first network device may locally obtain a UE policy related to the second terminal based on a policy update indication from the second terminal, wherein, upon determining based on an identifier of the second terminal that a UE policy corresponding to the second terminal is locally stored, the first network device may obtain, based on the policy update indication from the second terminal, a UE policy used by the second terminal and capable of being assigned to terminals other than the second terminal, and use the UE policy used by the second terminal and capable of being assigned to terminals other than the second terminal as the UE policy related to the second terminal. In this example, the first network device may simultaneously serve the first terminal and the second terminal.

[0219] Among them, obtaining the UE policy used by the second terminal and capable of being assigned to terminals other than the second terminal based on the policy update indication of the second terminal may include: obtaining the UE policy of the second terminal that can be assigned to terminals other than the second terminal, and extracting the UE policy used by the second terminal and capable of being assigned to terminals other than the second terminal from the UE policy of the second terminal that can be assigned to terminals other than the second terminal based on the policy update indication of the second terminal.

[0220] In one example, the first network device obtaining the UE policy related to the second terminal from the second network device based on the policy update indication of the second terminal may include: when the first network device determines based on the identifier of the second terminal that the second network device stores the UE policy corresponding to the second terminal, the first network device obtains the UE policy used by the second terminal and capable of being allocated to terminals other than the second terminal from the second network device based on the policy update information of the second terminal, and uses the UE policy used by the second terminal and capable of being allocated to terminals other than the second terminal as the UE policy related to the second terminal.

[0221] Here, the second network device may serve the second terminal; this embodiment does not limit the manner in which the first network device determines, based on the identifier of the second terminal, that the second network device stores the UE policy corresponding to the second terminal.

[0222] The first network device obtains, from the second network device based on the policy update information of the second terminal, a UE policy used by the second terminal and capable of being allocated to terminals other than the second terminal, which may include one of the following: the first network device obtains the policy update information of the second terminal from the second network device, and based on the policy update information of the second terminal, obtains, from the UE policy corresponding to the second terminal stored in the second network device, a UE policy used by the second terminal and capable of being allocated to terminals other than the second terminal; the first network device obtains, from the second network device, the UE policy corresponding to the second terminal and the policy update information of the second terminal, and extracts, from the UE policy corresponding to the second terminal based on the policy update information of the second terminal, a UE policy used by the second terminal and capable of being allocated to terminals other than the second terminal.

[0223] In some embodiments, the first identifier only includes an identifier of the first service. In this embodiment, the UE policy related to the second terminal includes: a UE policy used by the first service running on the second terminal that can be allocated to other terminals except the second terminal.

[0224] In one example, the first network device obtains the UE policy related to the second terminal from the local area based on the policy update indication of the second terminal, which may include: the first network device determines, based on the identifier of the first service, that there is a second terminal locally that runs the first service and has a binding relationship with the first terminal, and then, based on the policy update indication of the second terminal, obtains the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal that is stored locally, and uses the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal as the UE policy related to the second terminal.

[0225] The process in which the first network device determines whether there is a second terminal running the first service locally and having a binding relationship with the first terminal based on the identifier of the first service is the same as the above embodiment and will not be described in detail.

[0226] In one example, the first network device obtains the UE policy related to the second terminal from the second network device based on the policy update indication of the second terminal, which may include: the first network device obtains, from the second network device, the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal based on the identifier of the first service and the policy update indication of the second terminal, and uses the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal as the UE policy related to the second terminal.

[0227] Among them, the first network device obtains, from the second network device, a UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal based on the identifier of the first service and the policy update indication of the second terminal, which may include one of the following: the first network device obtains the UE policy corresponding to the second terminal and the policy update indication of the second terminal from the second network device, and extracts, from the UE policy corresponding to the second terminal, the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal; the first network device obtains the policy update indication of the second terminal from the second network device, and extracts, from the UE policy corresponding to the second terminal stored in the second network device, the UE policy that can be allocated to terminals other than the second terminal and used by the first service run by the second terminal based on the policy update indication of the second terminal and the identifier of the first service.

[0228] In one embodiment, the first identifier only includes an identifier of the first user. In this embodiment, the UE policy related to the second terminal includes: a UE policy used by the first user of the second terminal that can be allocated to other terminals except the second terminal.

[0229] In one example, the first network device obtains the UE policy related to the second terminal from the local area based on the policy update indication of the second terminal, which may include: based on the identifier of the first user, when the first network device determines that there is a second terminal used by the first user and has a binding relationship with the first terminal locally, the first network device obtains the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal stored locally based on the policy update indication of the second terminal, and uses the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal as the UE policy related to the second terminal.

[0230] The description of the first network device judging whether there is a second terminal locally used by the first user and bound to the first terminal based on the identifier of the first user is the same as that in the above embodiment and is not repeated here.

[0231] In one example, the first network device obtains the UE policy related to the second terminal from the second network device based on the policy update indication of the second terminal, which may include: the first network device obtains the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal from the second network device based on the identifier of the first user and the policy update indication of the second terminal, and uses the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal as the UE policy related to the second terminal.

[0232] Among them, the first network device obtains the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal from the second network device based on the identifier of the first user and the policy update indication of the second terminal, which may include one of the following: the first network device obtains the UE policy corresponding to the second terminal and the policy update indication of the second terminal from the second network device, and extracts the UE policy that can be assigned to terminals other than the second terminal from the UE policy corresponding to the second terminal based on the identifier of the first user and the policy update indication of the second terminal; the first network device obtains the policy update indication of the second terminal from the second network device, and extracts the UE policy that can be assigned to terminals other than the second terminal and used by the first user of the second terminal from the UE policy corresponding to the second terminal saved by the second network device based on the policy update indication of the second terminal and the identifier of the first user.

[0233] In some embodiments, the first identifier includes an identifier of the second terminal, and the first identifier further includes at least one of the following: an identifier of the first service, an identifier of the first user.

[0234] Optionally, the first identifier may include the identifier of the second terminal and the identifier of the first service, that is, the first identifier is used to indicate the first service running by the second terminal; accordingly, the UE policy related to the second terminal includes the UE policy corresponding to the second terminal, which is used by the second terminal and can be allocated to other terminals other than the second terminal.

[0235] Optionally, the first identifier may include the identifier of the second terminal and the identifier of the first user, that is, the first identifier is used to indicate the first user using the second terminal; accordingly, the UE policy related to the second terminal includes the UE policy used by the first service run by the second terminal that can be allocated to other terminals other than the second terminal.

[0236] Optionally, the first identifier may include an identifier of the second terminal, an identifier of the first service, and an identifier of the first user, that is, the first identifier is used to indicate the first user using the second terminal and the first service of the first user running on the second terminal. Accordingly, the UE policy related to the second terminal includes a UE policy used by the first user of the second terminal that can be assigned to other terminals other than the second terminal.

[0237] The possible contents of the UE policy related to the second terminal in the case of different combinations of the first identifier have been described in detail. In the examples provided below, the contents of the UE policy related to the second terminal in the case of different combinations of the first identifier will not be repeated.

[0238] In one example, the first network device obtains the UE policy related to the second terminal locally based on the policy update indication of the second terminal, which may include: when the first network device determines that the second terminal exists locally based on the identifier of the second terminal contained in the first identifier, the first network device obtains the locally stored UE policy related to the second terminal based on the identifier of the first service contained in the first identifier, at least one of the identifier of the first user, and the policy update indication of the second terminal.

[0239] In one example, the first network device obtaining the UE policy related to the second terminal from the second network device based on the policy update indication of the second terminal may include: when the first network device determines that there is no second terminal locally based on the identifier of the second terminal contained in the first identifier, the first network device obtains the UE policy related to the second terminal from the second network device based on the identifier of the first service contained in the first identifier, at least one of the identifier of the first user, and the policy update indication of the second terminal.

[0240] The first network device obtains the UE policy related to the second terminal from the second network device based on the identifier of the first service, at least one of the identifier of the first user, and the policy update indication of the second terminal contained in the first identifier. This may be: the first network device obtains the UE policy corresponding to the second terminal and the policy update indication of the second terminal from the second network device, and selects the UE policy related to the second terminal from the UE policies corresponding to the second terminal based on the identifier of the first service, at least one of the identifier of the first user, and the policy update indication of the second terminal contained in the first identifier of the first network device; or the first network device obtains the policy update indication of the second terminal from the second network device, and directly extracts the UE policy related to the second terminal from the UE policies corresponding to the second terminal stored on the second network device based on the identifier of the first service, at least one of the identifier of the first user, and the policy update indication of the second terminal. This will not be repeated here.

[0241] In some possible implementations, after the first network device generates the UE policy of the first terminal, the first network device may locally store the UE policy of the first terminal.

[0242] In this embodiment, in addition to locally storing the UE policy of the first terminal, the processing of the first network device may further include: the first network device sending second information, where the second information includes the UE policy of the first terminal. The relevant description of the second information is the same as that of the previous embodiment and is not repeated here.

[0243] That is, after the first network device generates a UE policy for the first terminal, the UE policy of the first terminal can be distributed to the network element serving the first terminal (for example, which may include the aforementioned first network device) and the first terminal.

[0244] In some possible implementations, the first terminal may further report information about the first capability, so that the first network device determines that the first terminal has the first capability.

[0245] The processing of the first terminal may also include: the first terminal sends an indication of a first capability, wherein the indication of the first capability is used to indicate that the first terminal has a first capability, and the first capability includes at least one of the following: the ability to support or allow UE policies related to the UE policy of this terminal to be allocated to other terminals, and the ability to support or allow UE policies related to UE policies of other terminals to be allocated to this terminal. Accordingly, the processing of the first network device may also include: the first network device receives an indication of a first capability, wherein the indication of the first capability is used to indicate that the first terminal has a first capability, and the first capability includes at least one of the following: the ability to support or allow UE policies related to at least part of the UE policy of this terminal to be allocated to one or more other terminals, and the ability to support or allow UE policies related to at least part of the UE policy of one or more other terminals to be allocated to this terminal.

[0246] The first terminal has the first capability, which may mean that the first terminal supports or allows any processing related to the first terminal under the operation corresponding to the first capability, and also supports or allows the network side (such as the first network device) to perform processing related to the first capability.

[0247] Here, the first terminal sending the first capability indication is the first terminal sending the first capability indication to the first network device; correspondingly, the first network device receiving the first capability indication is the first network device receiving the first capability indication sent by the first terminal.

[0248] The terminal involved in the first capability of the aforementioned first terminal refers to the first terminal; the other terminals involved refer to other terminals other than the first terminal. The other terminals are not used to specifically refer to one or more terminals, and as long as they are different from the first terminal, they are within the protection scope of this embodiment.

[0249] The indication of the first capability can indicate that the first terminal has the first capability through descriptive information; or, the indication of the first capability can indicate whether the first terminal has the first capability through the value of the indicator bit. For example, when the value of the indicator bit is the first value, it is used to indicate that the first terminal has the first capability; when the value of the indicator bit is the second value, it is used to indicate that the first terminal does not have the first capability. The first value and the second value can be set according to actual conditions. For example, the first value can be 0 and the second value can be 1, or the first value can be 1 and the second value can be 0. They are not exhaustively listed and limited here.

[0250] Optionally, the aforementioned first capability may only include a capability of supporting or allowing UE policies related to UE policies of other terminals to be allocated to the terminal.

[0251] In this case, the first network device may determine that the first terminal can only be assigned a UE policy related to at least part of the UE policy of any other terminal. Alternatively, the first network device may determine that the first terminal can not only be assigned a UE policy related to at least part of the UE policy of any other terminal, but can also assign the UE policy related to the first terminal to any other terminal other than the first terminal.

[0252] Among them, the UE policy related to the UE policy of other terminals includes: the UE policy related to at least part of the UE policy of each other terminal in at least part of one or more other terminals different from the first terminal. Furthermore, the UE policy related to at least part of the UE policy of any other terminal may include the first part of the UE policy in the UE policy related to any other terminal, and / or, the related policy of the second part of the UE policy in the UE policy related to any other terminal. The description of the UE policy related to any other terminal is similar to the UE policy related to the second terminal in the aforementioned embodiment; the description of the first part of the UE policy and the second part of the policy is also similar to the aforementioned embodiment, so it will not be repeated here.

[0253] Optionally, the aforementioned first capability may only include a capability of supporting or allowing UE policies related to the UE policy of the terminal to be distributed to other terminals.

[0254] In this case, the first network device may determine that the first terminal can only allocate UE policies related to at least part of its own UE policies to one or more other terminals. Alternatively, the first network device may determine that the first terminal can not only be allocated UE policies related to at least part of the UE policies of any other terminal, but also allocate UE policies related to the first terminal to any other terminal other than the first terminal.

[0255] Among them, the UE policy related to the UE policy of the terminal may include the first part of the UE policy in the UE policy related to the first terminal, and / or the related UE policy of the second part of the UE policy in the UE policy related to the first terminal. The description of the UE policy related to the first terminal is similar to the UE policy related to the second terminal in the aforementioned embodiment; accordingly, the description of the first part of the UE policy and the second part of the UE policy are also similar to the aforementioned embodiment, so they are not repeated here.

[0256] Optionally, the aforementioned first capability may include the capability of supporting or allowing UE policies related to the UE policies of the current terminal to be distributed to other terminals, and the capability of supporting or allowing UE policies related to the UE policies of other terminals to be distributed to the current terminal.

[0257] In some possible implementations, the first terminal sending the indication of the first capability and the first terminal sending the first information may be performed simultaneously.

[0258] The indication of the first capability and the first information may both be carried by an uplink UE policy container. The relevant description of the uplink UE policy container is the same as that of the above embodiment and will not be repeated here.

[0259] The indication of the first capability is sent simultaneously with the first information, so that the first network device can determine that the first terminal has the first capability, and the first terminal requests the first network device to start executing the UE policy related to the UE policy of other terminals assigned to the first terminal, and finally generate the UE policy processing of the first terminal.

[0260] In some embodiments, in a scenario where the first terminal simultaneously reports the first information and an indication of the first capability, after the first network device generates a UE policy for the first terminal, the first network device may only send the aforementioned second information to the first terminal, and the content of the second information is not repeated here. In other words, by sending the second information, the first network device implicitly indicates that it supports the first terminal in performing the function corresponding to the first capability and has completed the allocation of the first terminal's UE policy related to the second terminal's UE policy.

[0261] It should be noted that when the first network device simultaneously receives the first information and the indication of the first capability, the first network device may first determine whether to allow the first terminal to distribute UE policies related to the UE policy of the terminal to other terminals, and / or whether to allow the first terminal to distribute UE policies related to UE policies of other terminals. This embodiment does not limit the specific determination method of the first network device.

[0262] In the case where the first network device determines that the first terminal is allowed to distribute the UE policy related to the UE policy of the terminal to other terminals, and / or allows the first terminal to be allocated UE policies related to the UE policies of other terminals, the first network device can perform the aforementioned processing of generating the UE policy of the first terminal and sending the second information, which will not be repeated here. In addition, in the case where the first network device determines that the first terminal is not allowed to distribute the UE policy related to the UE policy of the terminal to other terminals, and / or does not allow the first terminal to be allocated UE policies related to the UE policies of other terminals, relevant technologies can be used to allocate the UE policy of the terminal to the first terminal. The specific generation method and sending method are not limited in this embodiment.

[0263] In some embodiments, in the scenario where the aforementioned first terminal simultaneously reports the first information and the indication of the first capability, after the first network device receives the first information and the indication of the first capability, the processing of the first network device may further include: the first network device sends a first indication, wherein the first indication is used to indicate at least one of the following: whether the first terminal is allowed to allocate UE policies related to the UE policy of the terminal to other terminals; whether the first terminal is allowed to allocate UE policies related to the UE policies of other terminals. Accordingly, the processing of the first terminal may further include: the first terminal receives the first indication, wherein the first indication is used to indicate at least one of the following: whether the first terminal is allowed to allocate UE policies related to the UE policy of the terminal to other terminals; whether the first terminal is allowed to allocate UE policies related to the UE policies of other terminals.

[0264] The aforementioned first network device sending the first indication means that the first network device sends the first indication to the first terminal; and the first terminal receiving the first indication means that the first terminal receives the first indication sent by the first network device.

[0265] In this embodiment, the first indication is sent at the same time as the second information after the first network device completes the allocation of the UE policy for the first terminal; or, the first indication is sent at the same time as the second information after the first network device confirms that the UE policy can be allocated for the first terminal. In this case, the first network device may not have generated or allocated the UE policy for the first terminal, that is, the first indication may be sent before the second information.

[0266] Furthermore, if the first indication and the second information are sent at the same time, the first indication and the second information can both be carried by the same downlink UE policy container in the UCU process. If the first indication is sent before the second information, the first indication and the second information can both be carried by different downlink UE policy containers in the UCU process. For example, the first indication can be carried by the first downlink UE policy container in the UCU process, and the second information can be carried by the second downlink UE policy container in the UCU process, wherein the first downlink UE policy container is different from the second downlink UE policy container, and the first downlink UE policy container is earlier than the second downlink UE policy container.

[0267] Preferably, in this embodiment, the first indication is at least used to indicate that the first network device allows allocation of UE policies related to UE policies of other terminals to the first terminal. In some possible examples, the first indication is used to indicate that the first terminal is allowed to allocate UE policies related to the UE policy of the terminal to other terminals, and to allow allocation of UE policies related to UE policies of other terminals to the first terminal.

[0268] In some possible implementations, the first terminal sending the first capability indication and the first terminal sending the first information may not be performed simultaneously. In this implementation, the first terminal may first send the first capability indication and then send the first information.

[0269] The indication of the first capability is carried by an uplink UE policy container. The uplink UE policy container includes one of the following: an uplink UE policy container in a registration request message, and an uplink UE policy container in a registration update message.

[0270] It should be noted that in this embodiment, the uplink UE policy container carrying the first capability indication is different from the uplink UE policy container carrying the first information. For example, the uplink UE policy container carrying the first capability indication may be the uplink UE policy container in the registration request message, and the uplink UE policy container carrying the first information may be the uplink UE policy container in the registration update message; for example, the uplink UE policy container carrying the first capability indication may be the first uplink UE policy container in the first registration request message, and the uplink UE policy container carrying the first information may be the uplink UE policy container in the second registration request message, and so on. All possible situations are not exhaustively listed here.

[0271] The indication of the first capability is the same as that in the above embodiment and will not be repeated.

[0272] In this embodiment, the processing after the first network device receives the indication of the first capability may include: the first network device may first determine whether the first terminal is allowed to allocate the UE policy related to the UE policy of the terminal to other terminals, and / or whether it is allowed to allocate the UE policy related to the UE policy of other terminals to the first terminal; when the first network device determines that the first terminal is allowed to allocate the UE policy related to the UE policy of the terminal to other terminals, and / or it is allowed to allocate the UE policy related to the UE policy of other terminals to the first terminal, the first network device may send a first indication of allowing the UE policy related to the UE policy of other terminals to be allocated to the first terminal. The first indication may be carried by the downlink UE policy container in the UCU process.

[0273] In addition, the present invention may further include: when the first network device determines that the first terminal is not allowed to allocate the UE policy related to the UE policy of the terminal to other terminals, and does not allow the first terminal to be allocated the UE policy related to the UE policy of other terminals, the first network device may send first information for indicating that the first terminal is not allowed to be allocated the UE policy related to the UE policy of other terminals. When the first network device sends the first information for indicating that the UE policy related to the UE policy of other terminals is not allowed to be allocated to the first terminal, the first network device may perform subsequent processing using the rules of the relevant protocol, which is not limited in this embodiment.

[0274] In some embodiments, in the scenario where the first terminal separately sends an indication of the first capability before sending the first information, when the first network device receives the indication of the first capability and sends a first indication allowing allocation of a UE policy related to UE policies of other terminals to the first terminal, the processing of the first network device may further include one of the following:

[0275] When the first network device determines that there is an allocated UE policy for the first terminal, and the allocated UE policy for the first terminal includes a UE policy that can be allocated to other terminals, the first network device may not perform any operation;

[0276] The first network device, upon determining that there is an allocated UE policy for the first terminal and the allocated UE policy for the first terminal does not include a UE policy that can be allocated to other terminals, updates the allocated UE policy for the first terminal based on the first capability of the first terminal, and generates a UE policy for the first terminal that can be allocated to other terminals;

[0277] When determining that there is no UE policy allocated to the first terminal, the first network device generates a UE policy of the first terminal that can be allocated to other terminals based on the first capability of the first terminal.

[0278] Among them, updating the allocated UE policy of the first terminal may refer to: deleting or adjusting at least part of the allocated UE policy of the first terminal, and / or adding new UE policies that can be allocated to other terminals to the allocated UE policy of the first terminal.

[0279] This embodiment does not limit the specific processing method of deleting, adjusting, or adding. This embodiment also does not limit the specific processing method of generating a UE policy of the first terminal that can be allocated to other terminals based on the first capability of the first terminal.

[0280] When the first network device generates a UE policy for the first terminal that can be assigned to other terminals, the first network device may further perform the following processing: the first network device sends third information, where the third information includes the UE policy for the first terminal that can be assigned to other terminals. Accordingly, after the first terminal sends the indication of the first capability, the method further includes: the first terminal receiving the third information.

[0281] It should be noted that the first network device may also generate a UE policy for the first terminal that cannot be assigned to other terminals. Accordingly, the third information may include, in addition to the UE policy for the first terminal that can be assigned to other terminals, UE policies for the first terminal that cannot be assigned to other terminals. In other words, the UE policy for the first terminal that can be assigned to other terminals may be part of the total UE policy currently assigned to the first terminal.

[0282] Here, the third information can be carried by a downlink UE policy container, and the downlink UE policy container can be a downlink UE policy container in the UCU process. It should be noted that in this embodiment, the third information and the second information are not sent at the same time. Therefore, the downlink UE policy container carrying the third information is different from the downlink UE policy container carrying the second information; for example, the third information can be carried by the downlink UE policy container in the first UCU process initiated or triggered by the first network device, and the second information can be carried by the downlink UE policy container in the second UCU process initiated or triggered by the first network device.

[0283] In some embodiments, in the aforementioned scenario where the first terminal sends the first capability indication before sending the first information, after the first network device receives the first capability indication, the processing of the first network device may further include: the first network device sending the first indication. The description of the first indication is the same as in the aforementioned embodiment and is not repeated here.

[0284] In some examples, when the first network device determines that there is an allocated UE policy for the first terminal and the allocated UE policy for the first terminal includes a UE policy that can be allocated to other terminals, the first network device may only send a first indication to the first terminal, and the first indication is used to indicate that UE policies related to the UE policy of the first terminal are allowed to be allocated to other terminals, and / or that UE policies related to the UE policies of other terminals are allowed to be allocated to the first terminal.

[0285] In some examples, when the first network device generates a UE policy for the first terminal that can be allocated to other terminals, the first network device can send the aforementioned third information to the first terminal and send a first indication, and the first indication is used to indicate that the UE policy related to the UE policy of the first terminal is allowed to be allocated to other terminals, and / or that the UE policy related to the UE policy of other terminals is allowed to be allocated to the first terminal.

[0286] The aforementioned third information and first indication can be sent at the same time. For example, the third information and the first indication can also be carried by the same downlink UE policy container in the UCU process, or the third information and the first indication can also be carried by different downlink UE policy containers in the UCU process. There is no limitation on the order in which the first network device sends the first indication and the third information.

[0287] In some examples, if the first network device determines that the first terminal is not allowed to perform the function corresponding to the first capability, the first network device may send a first indication to the first terminal indicating that the first terminal is not allowed to distribute UE policies related to the UE policy of the terminal to other terminals, and / or that UE policies related to UE policies of other terminals are not allowed to be distributed to the first terminal. In this case, the first network device performs the subsequent processing flow specified in the relevant protocol for the first terminal, which is not limited here.

[0288] In some embodiments, the first terminal may send the first information to the first network device after receiving the aforementioned third information and / or first indication. The processing of the first network device after receiving the first information is the same as that in the aforementioned embodiment and will not be repeated here.

[0289] In some possible implementations, the processing of the first device sending the first information needs to be based on the network side (for example, it can be the first network device serving the first terminal and the second terminal, or the second network device serving the second terminal) having allocated the UE policy related to the second terminal. Therefore, the processing that the second terminal and the second network device need to perform before the first device sends the first information is explained below.

[0290] The second terminal sends an indication of the first capability, which may specifically be: the second terminal sends an indication of the first capability to the second network device. Correspondingly, the second network device receives the indication of the first capability of the second terminal, which may be: the second network device receives the indication of the first capability of the second terminal sent by the second terminal. The indication of the first capability is used to indicate that the second terminal has the first capability, and the first capability includes at least one of the following: the ability to support or allow UE policies related to the UE policy of this terminal to be allocated to other terminals, and the ability to support or allow UE policies related to UE policies of other terminals to be allocated to this terminal.

[0291] It should be pointed out that the network device corresponding to the second terminal will be referred to as the second network device below, but the description of the second network device below does not mean that it cannot be used for the first network device. When the first network device serves the first terminal and the second terminal at the same time, the second network device involved below can be replaced by the first network device, but the description will not be repeated.

[0292] The indication of the first capability of the second terminal is carried by an uplink UE policy container. The uplink UE policy container includes at least one of the following: an uplink UE policy container in a registration request message, and an uplink UE policy container in a registration update message.

[0293] Specifically, the second terminal sending an indication of the first capability to the second network device may include: the second terminal carrying the indication of the first capability in an uplink UE policy container in a registration request message or a registration update message, sending the registration request message or the registration update message to the fifth network device, and the fifth network device sending the uplink UE policy container carrying the indication of the first capability of the second terminal to the second network device. Correspondingly, the second network device receiving the indication of the first capability of the second terminal sent by the second terminal may include: the second network device receiving the uplink UE policy container carrying the indication of the first capability of the second terminal sent by the second terminal through the fifth network device. The fifth network device may be an AMF serving the second terminal.

[0294] The second terminal can be any terminal other than the first terminal, or the second terminal can be any terminal that has the first capability and is bound to the first terminal. In the first capability of the second terminal, the reference to the terminal itself refers to the second terminal; any one of the one or more other terminals refers to any other terminal other than the second terminal.

[0295] The indication of the first capability of the second terminal may indicate that the second terminal has the first capability through a description information, or the indication of the first capability of the second terminal may indicate whether the second terminal has the first capability through the value of the indication bit.

[0296] The detailed description of the first capability of the second terminal is similar to that of the first capability of the first terminal in the aforementioned embodiment, and thus will not be repeated.

[0297] In some embodiments, after the aforementioned second network device receives the indication of the first capability of the second terminal, the method may further include: the second network device generating a UE policy corresponding to the second terminal based on the first capability of the second terminal.

[0298] Specifically, the processing of the second network device may include one of the following:

[0299] When the second network device determines that there is an allocated UE policy for the second terminal, and the allocated UE policy for the second terminal includes a UE policy that can be allocated to other terminals, the second network device may not perform any operation;

[0300] The second network device, upon determining that there is an allocated UE policy for the second terminal and the allocated UE policy for the second terminal does not include a UE policy that can be allocated to other terminals, updates the allocated UE policy for the second terminal based on the first capability of the second terminal, and generates a UE policy corresponding to the second terminal;

[0301] When determining that there is no UE policy allocated to the second terminal, the second network device generates a UE policy corresponding to the second terminal based on the first capability of the second terminal.

[0302] Among them, updating the allocated UE policy of the second terminal to generate a UE policy corresponding to the second terminal may refer to: deleting or adjusting at least part of the allocated UE policy of the second terminal to generate a UE policy corresponding to the second terminal; and / or, adding a new UE policy that can be allocated to other terminals to the UE policy corresponding to the second terminal.

[0303] This embodiment does not limit the specific processing method of deleting, adjusting, or adding. This embodiment also does not limit the specific processing method of generating a UE policy corresponding to the second terminal based on the first capability of the second terminal.

[0304] When the second network device generates a UE policy corresponding to the second terminal, the second network device may further perform the following processing: the second network device transmits fourth information, wherein the fourth information includes the UE policy corresponding to the second terminal, and the UE policy corresponding to the second terminal includes UE policies that can be assigned to other terminals. Accordingly, after the second terminal transmits the indication of the first capability, the method further includes: the second terminal receiving the fourth information.

[0305] Here, the fourth information may be carried by a downlink UE policy container, and the downlink UE policy container may be a downlink UE policy container in a UCU process. The second network device sending the fourth information may include: carrying the fourth information in a downlink UE policy container, initiating or triggering a UCU process, and sending the downlink UE policy container to the second terminal through a fifth network device in the UCU process. The second terminal receiving the fourth information may include: receiving the downlink UE policy container sent by the second network device through the fifth network device in the UCU process, and obtaining the UE policy corresponding to the second terminal included in the fourth information from the downlink UE policy container.

[0306] In some embodiments, after the second network device receives an indication of the first capability of the second terminal, the method further includes: the second network device sends a second indication, wherein the second indication is used to indicate at least one of the following: whether the second terminal is allowed to allocate UE policies related to the UE policies of the terminal to other terminals; whether it is allowed to allocate UE policies related to UE policies of other terminals to the second terminal.

[0307] After receiving the indication of the first capability of the second terminal, the second network device can determine whether to allow the second terminal to distribute UE policies related to the UE policies of the terminal to other terminals, and / or whether to allow the second terminal to be allocated UE policies related to the UE policies of other terminals.

[0308] In some examples, when the second network device determines that there is an allocated UE policy for the second terminal and the allocated UE policy for the second terminal includes a UE policy that can be allocated to other terminals, the second network device may only send a first indication to the first terminal. The first indication may be used to indicate that the second terminal is allowed to allocate UE policies related to the UE policy of the terminal to other terminals, and / or allow the second terminal to be allocated UE policies related to the UE policies of other terminals.

[0309] In some examples, when the second network device generates a UE policy corresponding to the second terminal, the second network device can send the aforementioned fourth information to the second terminal and send a second indication, and the second indication is used to indicate that the UE policy related to the UE policy of the second terminal is allowed to be allocated to other terminals, and / or that the UE policy related to the UE policy of other terminals is allowed to be allocated to the second terminal.

[0310] The fourth information and the second indication may be sent simultaneously. For example, the fourth information and the second indication may be carried by the same downlink UE policy container in the UCU process, or the fourth information and the second indication may be carried by different downlink UE policy containers in the UCU process.

[0311] In some examples, if the second network device determines that the second terminal is not allowed to perform the function corresponding to the first capability, the second network device may send a second indication to the second terminal indicating that the second terminal is not allowed to distribute UE policies related to the UE policy of the terminal to other terminals, and / or that UE policies related to UE policies of other terminals are not allowed to be distributed to the second terminal. In this case, the second network device performs the subsequent processing flow specified in the relevant protocol for the second terminal, which is not limited here.

[0312] In some possible implementations, after the second terminal receives the fourth information, the method further includes: the second terminal sending a policy update indication, wherein the policy update indication is used to determine a UE policy used by the second terminal in a UE policy corresponding to the second terminal. After the second network device sends the fourth information, the method further includes: the second network device receiving a policy update indication, wherein the policy update indication is used to determine a UE policy used by the second terminal in a UE policy of the second terminal.

[0313] The relevant description of the policy update indication is the same as that in the above embodiment and will not be repeated here.

[0314] The method for the second terminal to send the policy update indication may include: the second terminal reports the policy update indication to the SMF during the PDU session modification / establishment process, and the policy update indication may include that the PDU session is established using a certain UE policy; the SMF sends the policy update indication to the second network device.

[0315] Alternatively, the method for the second terminal to send the policy update indication may include: the second terminal carries the policy update indication in an uplink UE policy container, triggers the registration process and sends the uplink UE policy container to the fifth network device, and the fifth network device sends the uplink policy container to the second network device.

[0316] It should be understood that the above embodiment only describes how to generate a UE policy corresponding to a second terminal. In actual processing, after the UE policy corresponding to the second terminal is assigned, the second terminal may also perform the aforementioned first terminal sending the first information and the related processing thereafter. For example, the second terminal can be used as the new first terminal in the aforementioned embodiment, and the third terminal can be used as the new second terminal in the aforementioned embodiment and perform the various processing corresponding to the first terminal in the aforementioned embodiment. This description will not be repeated here.

[0317] The communication method provided in this embodiment is exemplarily described below in conjunction with various embodiments.

[0318] 11, the process of the first terminal or the second terminal sending the indication of the first capability is exemplarily described, specifically:

[0319] Step 1101: UE-1 sends a registration request to the AMF. Specifically, the indication of the "first capability" is carried in the uplink UE Policy Container in the registration request.

[0320] Steps 1102-1103: The AMF sends the UE policy container containing support for the first capability to the PCF. The PCF may generate a UE policy for UE-1 based on the "first capability." For example, this UE policy may be applicable to other UEs, adding, deleting, or updating portions of the UE policy for UE-1 based on the UE's "first capability."

[0321] In this embodiment, since only one UE reporting the first capability is described, FIG11 may include only one UE.

[0322] In one case, UE-1 in Figure 11 may be the aforementioned second terminal, and the PCF in Figure 11 may be the aforementioned second network device serving the second terminal (such as the second PCF in the aforementioned embodiment). The indication of the first capability in step 1101 may be the indication of the first capability of the second terminal in the aforementioned embodiment.

[0323] In another case, UE-1 in Figure 11 may be the aforementioned first terminal, and the PCF in Figure 11 may be the aforementioned first network device serving the first terminal (such as the first PCF in the aforementioned embodiment). The indication of the first capability in step 1101 may be the indication of the first capability of the first terminal in the aforementioned embodiment.

[0324] It should be understood that, in some possible cases, the PCF may be a network device serving the first terminal and the second terminal.

[0325] In step 1103, the AMF may forward the uplink UE policy container to the PCF through PCF association establishment / modification (association est. / mod.), and then the PCF may send the same or associated UE policy as UE-1 to another UE-2 according to the "first capability" indication.

[0326] Steps 1104 to 1106: The AMF receives the message sent to the UDM requesting the subscription information (the message may be specifically the User Subscription Data Acquisition Service (Nudm_SDM_Get) message as shown in FIG11 ). The UDM replies to the AMF with the MM subscription information corresponding to UE-1. The AMF generates the UE Context in AMF context based on the MM subscription information, and the AMF sends a Registration Accept message to UE-1. The MM subscription information corresponding to UE-1 replied by the UDM to the AMF may be carried in the User Subscription Data Acquisition Service Response message (Nudm_SDM_Get_response) shown in FIG11 .

[0327] Step 1107: The PCF triggers the UCU process to send the UE policy to UE-1.

[0328] When UE-1 is the first terminal in the aforementioned embodiment, the UE policy of UE-1 may include the UE policy of the first terminal in the aforementioned embodiment that can be allocated to other terminals. When UE-1 is the second terminal in the aforementioned embodiment, the UE policy of UE-1 may be the UE policy corresponding to the second terminal in the aforementioned embodiment.

[0329] The UCU process may be independent of the registration process, and its occurrence order may be independent of other steps (eg, occurring at a certain time point before step 1106 of the registration process).

[0330] It should be noted that other network devices, such as SMF and RAN, are also illustrated in Figure 11. The SMF is a device on the core network side and is shown in Figure 11 to illustrate the integrity of the architecture. The RAN can be an access network device serving the UE, and the role of the RAN in the example of Figure 11 is also not limited.

[0331] In conjunction with Figure 12, taking the second terminal as UE-1 in Figure 12 and the second network device as the PCF in Figure 12 as an example, the process of PCF triggering the UCU process to send the UE policy of the UE to the UE is further described:

[0332] Step 1200: The PCF generates or updates a UE policy based on the indication of the "first capability," and / or generates a "first indication." The "first indication" indicates at least one of: whether UE-1 is allowed to migrate the UE policy of other UEs; and whether UE-1 is allowed to allow other UEs to migrate their UE policies. The first indication may be the second indication sent by the second network device to the second terminal in the aforementioned embodiment.

[0333] In some possible cases, the PCF may predetermine the content of the UE policy that allows migration, such as the specific UE policy that allows migration, such as the URSP policy; which rules under the UE policy that allows migration, such as the URSP rule that contains the Connection Capability parameter in the URSP policy; which content in a certain rule that allows migration, such as the TD that contains specific parameters in the URSP.

[0334] In some possible cases, the first indication may also include the content of the UE policy that allows migration, such as the specific UE policy that allows migration, such as the URSP policy; which rules under the UE policy that allows migration, such as the URSP rule that contains the Connection Capability parameter in the URSP policy; which content in a certain rule that allows migration, such as the TD that contains specific parameters in the URSP.

[0335] Step 1201: The PCF places the generated UE policy into a downlink UE policy container and calls the N1 and N2 interface communication message transfer message (Namf_Communiaction_N1N2Message Transfer) to send the downlink UE policy container carrying the UE policy to the AMF.

[0336] Step 1202: The AMF sends the downlink UE policy container to UE-1 via a DL NAS Transport message.

[0337] It should be noted that before executing step 1202, there may be an optional step: if UE-1 is in the idle state, the AMF initiates a network triggered service request (Network Triggered Service Request) to enable UE-1 to enter the connected state.

[0338] Steps 1203-1204: After UE-1 configures the UE policy, it sends a reply message to the PCF via the AMF to determine whether the configuration is successful. In step 1203, UE-1 sends the UE policy configuration result to the AMF, and in step 1204, the AMF sends the UE policy configuration result to the PCF via the N1 interface notification message (Namf_Communication_N1MessageNotify).

[0339] In conjunction with Figure 13, when UE-2 (the first terminal in the aforementioned embodiment) takes over part or all of the services of UE-1 (the second terminal in the aforementioned embodiment), the UE policy of UE-1 needs to be sent to UE-2 for use. Specifically:

[0340] Step 1301: The UE sends a registration request message to the AMF, which includes an uplink UE Policy Container. The uplink UE Policy Container carries at least one of the following parameters: an indication of a "first capability"; a "first request": the "first request" is used to indicate that part or all of the policy information of other UEs needs to be allocated to the UE for use; a "first identifier" includes one or more of the following: 1) an identifier of the associated UE-1: that is, the existing UE policy of which UE is to be allocated; 2) an associated service (or application) identifier: that is, the UE policy corresponding to which service is to be allocated. This identifier can be used together with 1) to further limit the content to be allocated, or it can be used alone; 3) an associated user identifier: that is, the UE policy corresponding to which user identifier is to be allocated. Multiple UEs such as UE-1 and UE-2 can be used by the same user, so the context information between multiple UEs can be associated through the user identifier.

[0341] Step 1302: The AMF may forward the uplink UE policy container to the PCF through PCF association establishment / modification (association est. / mod.).

[0342] Step 1303 (optional): The PCF performs a UE policy retrieval on the UDR. During the retrieval process, the PCF sends the indication of the "first capability" and / or the "first request" and / or the "first identifier" in the uplink UE policy container to the UDR.

[0343] Step 1304: The PCF determines a UE policy that is the same as or associated with UE-1 based on one or more parameters in the uplink UE policy container. The one or more parameters refer to an indication of a "first capability" and / or a "first request" and / or a "first identifier".

[0344] Step 1305: AMF sends a Registration accept to UE-2.

[0345] Step 1306: PCF sends the UE policy to UE-2 via the UCU process. The UCU process can be independent of the registration process, and its occurrence order can also be independent of other steps (eg, occurring at a time point before step 1305 of the registration process).

[0346] The process of PCF assigning UE policy to UE-2 is described with reference to FIG14 :

[0347] Step 1400: UE-1 reports / updates the currently used UE policy.

[0348] This step is optional and applies to "dynamic mode". When a UE (any UE) receives a UE policy, it may use different UE policies due to differences in time, usage, and implementation. In other words, in some cases, even if the UE policies sent by multiple UEs are the same, different UEs may use different rules under the same UE policy. For this reason, when migrating UE policies, "dynamic mode" allows UE-2 to use the UE policy rules currently used by UE-1, which can better ensure consistency in service experience.

[0349] For example, if a URSP policy includes rule-1 and rule-2, both rules can be used for Tencent Video services. When a user uses UE-1, UE-1 uses rule-1 to establish a PDU session to transmit data related to the user's Tencent Video service. When the user subsequently uses UE-2, UE-2 should also use rule-1 (not rule-2) to transmit the user's video service. The session configuration parameters for different rules may vary, which may affect the service experience.

[0350] There are two ways for UE-1 to report / update the currently used UE policy: During the PDU session establishment / modification process, UE-1 reports which URSP rule and / or RSD was used to establish the session. This information can be further sent to the PCF via the SMF. UE-1 uses the UE Policy Container to report the currently used URSP rule and / or RSD. UE-1 can send this information to the PCF by triggering a registration process and carrying the UE Policy Container. Note: This example uses URSP; other UE policies can also be considered, but this example is not exhaustive.

[0351] Step 1401: PCF generates or updates the UE policy of UE-2 based on the parameters contained in the uplink UE policy container of the registration process ("first capability" indication and / or "first request", "first identification"), and / or the UE policy used reported by UE-1 (such as the policy update indication in the aforementioned embodiment).

[0352] Step 1402 (optional): When the PCF generates or updates the UE policy of UE-2, the PCF may interact with the UDR to jointly determine.

[0353] The UE policy for UE-2 generated based on the above parameters and information may include the following possibilities:

[0354] 1) Only include the UE policy that UE-2 needs to use. For example, in the example of step 0, if the PCF only wants UE-2 to use Rule-1 currently used by UE-1, then the UE policy includes Rule-1 but not Rule-2.

[0355] 2) The UE policy sent to UE-2 includes a "second indication" (i.e., the selection indication information in the aforementioned embodiment). The "second indication" is used to indicate which rules UE-1 is currently using, or to indicate which rules UE-2 prioritizes or requires to use.

[0356] 3) UE-2's UE policy directly copies the policy content (parameters) of UE-1, or the UE policies of UE-1 and UE-2 are associated, but the content or parameter values ​​are different. For example, the UE policies of UE-1 and UE-2 correspond to the same User ID, or the TD parameters in the URSP rules of UE-1 and UE-2 are the same, but the RSD parameters under each TD are different.

[0357] Steps 1403-1405: The PCF sends the UE policy to UE-2 and receives a reply message from UE-2, which provides feedback on whether the configuration is successful.

[0358] In step 1403, the PCF places the generated UE policy for UE-2 into the downlink UE policy container and calls the N1 and N2 interface communication message transfer message (Namf_Communiaction_N1N2Message Transfer) to send the downlink UE policy container to the AMF.

[0359] It should be noted that before executing step 1404, there may be an optional step: if UE-2 is in the idle state, the AMF initiates a network triggered service request (Network Triggered Service Request) to enable UE-2 to enter the connected state.

[0360] Step 1404: The AMF sends the downlink UE policy container carrying the UE policy of UE-2 to UE-2 via a DL NAS Transport message.

[0361] In step 1405, UE-2 sends the configuration result of the UE policy to the AMF.

[0362] By adopting the solution provided in the above embodiment, a first terminal can request that a UE policy related to the UE policy of another terminal be assigned to it by sending a first message. The first terminal then receives a second message, which includes the UE policy of the first terminal related to the UE policy of the second terminal. In this way, by assigning the UE policy related to the second terminal to the first terminal, at least part of the second terminal's services can be migrated to a different device, thereby achieving the effect of coordinating the same service on multiple devices. While achieving service migration, it also ensures that communication capabilities remain unchanged or optimized, thereby ensuring service continuity.

[0363] Furthermore, the solution provided by the aforementioned embodiment can be enhanced in the existing process, the impact on the existing architecture can be controlled, and policy migration between different terminals can be realized; in the aforementioned embodiment, the migration or replication of specific UE policy content can be realized by indicating a first identifier, such as a first service identifier, a first user identifier or an association relationship between terminals. In this way, according to the needs of the scenario, by supporting the requirements of communication, computing and business continuity, the multi-terminal collaboration capability of the business of a specific user on different devices is realized, thereby achieving the best business experience.
