Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to an information processing method, apparatus, communication device, and storage medium. Background Art

[0002] Different from terminal subscription or terminal identifiers, in order to identify a specific user or user identity, for example, to identify the user or person holding the terminal, etc., the mobile network can define an identifier for identifying the user, which can also be called a user identity identifier. User identity identifiers can be divided into user identifiers (User ID) and digital identity (Digital Identity) identifiers based on different application scopes and security levels.

[0003] Among them, the user identifier is different from the existing network's subscription user identifier for authenticating terminals. Compared with the digital identity, the user identifier has a limited application scope and a relatively low security level. For example, for a single application scenario or a specific application service, an individual user can use different user identifiers to obtain corresponding services or services of corresponding levels, or assign different user identifiers to different network devices to obtain corresponding service permissions, etc.

[0004] The digital identity identifier is the unique identity identifier of an individual user in the virtual network space. Its application scope is the entire network and it is under the highest-level security control. Among them, the mobile network manages the context related to the digital identity identifier, which includes user identifiers, device information, security parameters, service policies, etc. An individual user can open a digital identity with an operator or other service providers. After the network side verifies that the user of the digital identity is the identity owner (i.e., the individual user), the authorized user can publish a new user identifier.

[0005] In addition, in network communication, communication devices communicate with the data network based on terminal subscription information. For example, initiating registration, registration update, session establishment, etc. However, when the above identifiers are introduced in network communication, or when using the above identifiers of a certain user, there is currently no feasible solution for how to process the above-related network requests.

[0068] In the present application, the first communication device or the second communication device may include at least one of a terminal, a base station, and a network-side device.

[0069] Next, with reference to the accompanying drawings, the information processing method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0070] An embodiment of the present application provides an information processing method, which is applied to a first communication device. The first communication device may include at least one of a terminal and a network-side device (such as AMF, SMF); asFigure 2 As shown, the method may include the following steps 201 to 203:

[0071] Step 201: The first communication device receives at least one of a first request and a second request.

[0072] Wherein, the first request is used to request to establish a connection with a data network, and the second request is used to request an identifier-related service

[0073] In addition, the first request may be used to request an application or a terminal to establish a connection with a data network (for example, an application requests to establish a socket connection); the second request may be used to request to request an identifier-related service from at least one network-side device (for example, a service for establishing a session).

[0074] Step 202: The first communication device receives a first message related to an identifier.

[0075] In this application, the identifier is used to identify or recognize at least one of a user and an application. Among them, the form of the user can be an account number or a digital identity, and the form of the application can be an application identifier. That is, the identifier realizes the identification, recognition, authentication, or verification of a human, or a real person, or a real user, or the identity of a real person by identifying the user.

[0076] Optionally, the identifier may include at least one of the following: user identifier, digital identity identifier, identity identifier, digital identifier, application identifier, account number, identity number, biometric information.

[0077] It should be noted that the biometric information includes digital parameters such as fingerprints, irises, and faces, and this raw data can be managed by an authoritative security agency.

[0078] In different application scenarios or different application services, the identifiers of the same user may be different, but in the same application scenario or the same application service, the identifiers of different users are different;

[0079] Regardless of whether it is in the same application scenario or the same application service, the digital identity of the same user is different.

[0080] Therefore, it can be understood that the above-mentioned identifier for identifying a user is different from the terminal identifier (or device identifier). That is, the terminal identifier is used to identify a terminal, a device, or a subscribed user. For example, the Subscription Permanent Identifier (SUPI), Generic Public Subscription Identifier (GPSI), etc. in 3GPP can also be an identification code similar to the International Mobile Subscriber Identity (IMSI). However, the above-mentioned identifier related to the first message is used to identify a user. For example, there is only one identifier for a terminal. However, since different users can use the terminal, for example, different family members can use it, a terminal can be associated with multiple identifiers.

[0081] In addition, it should be noted that the above-mentioned biometric information can also be used for authentication. For example, authentication of the user's identity can be performed based on at least one of parameters such as the biometric information of an individual user, the device information used, the network connection information, and the algorithm key. Among them, the mobile network can obtain the encrypted version of the biometric information from a security institution or directly request the security institution to perform verification and return the verification result. When an individual user accesses the mobile network through a terminal, the terminal obtains the biometric information of the individual user (such as fingerprint, face, etc.) and encrypts and sends the above information to the network-side device. When the mobile network obtains the encrypted version of the biometric information, it completes the authentication of the individual user's identity based on the information obtained from the security institution and the terminal side. In addition, the mobile network can also obtain the terminal information of the user, determine whether it is a subscribed user device, or comprehensively consider network information such as the current location and access technology of the individual user to give the final confidence level.

[0082] It should also be noted that the above-mentioned first message is related to the identifier, which can be understood as the content indicated by the first message is related to the identifier, or the first message indicates the relevant information of the identifier.

[0083] It should also be noted that the term "related" in this application can also be understood as: associated, relevant, having an associated relationship, having a corresponding relationship, etc. In one implementation, the first message is related to the identifier, which can be understood as that after using the identifier, the configuration information of the corresponding terminal or network device is at least one parameter included in the first message; or it can be understood that when the terminal, application, or network device uses the identifier, the terminal, application, or network device needs to use or configure at least one parameter included in the first message. It can also be understood that at least one item included in the first message is a set of parameters of the terminal, communication device, or application that matches the identifier.

[0084] Alternatively, the first message is related to the identifier, and it can also be understood as at least one of the following:

[0085] The first message carries the identifier;

[0086] At least one parameter included in the first message is related to the identifier, or has a corresponding relationship with the identifier; when using the identifier, the terminal, network device, application, etc. need to change their own configuration to at least one parameter or configuration included in the first message.

[0087] Step 203: The first communication device performs at least one of the following according to the first message:

[0088] Reject or accept or send the first request;

[0089] Reject or accept or send the second request.

[0090] It can be seen from step 203 that the first message related to the identifier can indicate whether the first communication device accepts at least one of the above first request and second request; that is, it can be understood that: the first communication device can determine whether to accept at least one of the above first request and second request according to the identifier-related information indicated by the first message.

[0091] In one implementation, the first communication device receives the first message through at least one of the following:

[0092] Protocol Data Unit (PDU) session establishment acceptance;

[0093] Registration acceptance;

[0094] PDU session modification acceptance;

[0095] Public Data Network (PDN) connection establishment acceptance;

[0096] Downlink Non-Access Stratum (NAS) message;

[0097] N2 message;

[0098] RRC message;

[0099] N1N2 Message Transfer (Namf_Communication_N1N2MessageTransfer), where N1 and N2 respectively represent an interface;

[0100] Subscription Data Management (Nudm_SDM_Get);

[0101] UE Policy Control Create Response (Npcf_UEPolicyControl Create Response);

[0102] UE Policy Control Update Response (Npcf_UEPolicyControl Update Response);

[0103] SM Policy Control Create Response (Npcf_SMPolicyControl Create Response);

[0104] SM Policy Control Update Response (Npcf_SMPolicyControl Update Response);

[0105] In one implementation, the first message may also be carried in the UE RouteSelection Policy (URSP) rule of the terminal and sent to the first communication device (such as the terminal).

[0106] In one implementation, the terminal sends a registration request or an uplink NAS message to the AMF, and the registration request or the uplink NAS message includes at least one of the following:

[0107] Identifier;

[0108] UE policy container corresponding to the identifier; the terminal policy carried in the UE policy container is determined or sent by the network side according to the identifier;

[0109] Terminal capability, the terminal has the following capabilities or supports at least one of the following: supporting the use of the identifier, supporting on boarding the identifier, supporting going online with the identifier, supporting activating the identifier, supporting establishing the identifier, supporting creating the identifier, supporting enabling the identifier.

[0110] Wherein, the registration request is used to carry the terminal policy stored in the terminal, and the terminal policy is related to the identifier; or, the registration request is used to declare the terminal capabilities.

[0111] In addition, the AMF sends at least one of the identifier and the UE policy container corresponding to the identifier to the PCF;

[0112] The AMF sends a terminal policy control establishment request (Npcf_UEPolicyControl Create Request) or a terminal policy control update request (Npcf_UEPolicyControl Update Request) to the PCF. The request is used to establish a terminal policy association and request a terminal policy for the terminal or the identifier. The request includes: terminal capabilities, identifier, and the UE policy container corresponding to the identifier;

[0113] The PCF sends a terminal policy control establishment response (Npcf_UEPolicyControl CreateResponse) or a terminal policy control update response (Npcf_UEPolicyControl Update Response) to the AMF. The response carries the terminal policy, which is related to the identifier, that is, the terminal policy is generated based on at least one of the identifier and the terminal capabilities and can only be used for the identifier.

[0114] In one implementation, in the URSP rule, or in the traffic descriptor or the route selection descriptor, an identifier may be included or carried.

[0115] In one implementation, the terminal establishes a PDU session according to the identifier sent or requested by the application, or associates or matches the traffic of the application to the corresponding session (the session corresponding to the identifier).

[0116] In one implementation, the application provides or requests an identifier, and the terminal performs matching parameters to find whether there is a corresponding identifier for the identifier provided or requested by the application in the URSP rule; if so, the URSP rule is executed, and at least one PDU session parameter in the route selection descriptor (RSD) corresponding to the identifier in the URSP rule is used to establish a session, or it is matched to a PDU session, and the PDU session parameter is the same as at least one parameter in the RSD.

[0117] In one implementation, at least one of the core network devices, such as the PCF, generates or determines a terminal policy according to an identifier; when the terminal uses or goes online with the identifier, the core network device updates the terminal policy to the terminal side according to the identifier, and the terminal policy is related to the identifier or dedicated to the identifier.

[0118] In one implementation, when the terminal uses or goes online with a new identifier, the terminal sends a registration request or an uplink NAS message to request the UE policy corresponding to the identifier.

[0119] It can also be known from step 203 that the first message related to the identifier can indicate whether the first communication device sends at least one of the above first request and second request; that is, it can be understood that the first communication device can determine whether to send at least one of the above first request and second request according to the identifier-related information indicated by the first message.

[0120] Among them, the first communication device can accept the first request according to the identifier-related information indicated by the first message. For example, when the first communication device is a terminal, the terminal receives the first message, and the first message indicates that the request corresponding to the first identifier is allowed. In this case, if the terminal receives the first request sent by the application, and the first request is used to establish a socket connection corresponding to the first identifier, the terminal accepts the first request according to the first message and establishes a socket connection corresponding to the first identifier;

[0121] Or for example, when the first communication device is an SMF, the SMF receives the first message, and the first message indicates that the session establishment request or session modification request corresponding to the second identifier is allowed or agreed. Then, after the SMF receives the first request from the terminal, the first request carries the second identifier and is used to establish a session corresponding to the identifier. The SMF agrees to the first request and establishes a PDU session for the second identifier associated with the terminal;

[0122] Similarly, the first communication device can reject the first request according to the identifier-related information indicated by the first message. For example, when the first communication device is a terminal, the terminal receives the first message, and the first message indicates that the request corresponding to the third identifier is rejected. In this case, if the terminal receives the first request sent by the application, and the first request is used to establish a socket connection corresponding to the third identifier, the terminal rejects the first request according to the first message and refuses to establish a socket connection corresponding to the third identifier; among them, the terminal will also feedback a response to the application, and the response indicates that the first request of the application is rejected, and the reason for the rejection is: rejecting the request related to the third identifier, or rejecting to establish a socket connection for the third identifier.

[0123] Alternatively, for example, when the first communication device is the SMF, the SMF receives the first message, which indicates to reject or not allow the session establishment request or session modification request corresponding to the fourth identifier. After the SMF receives the first request from the terminal, the first request carries the fourth identifier and is used to establish a session corresponding to the fourth identifier. Then, the SMF rejects the request and sends a PDU session establishment rejection to the terminal, rejecting the establishment of a PDU session for the fourth identifier associated with this terminal. Among them, the terminal will also send back a PDU session establishment rejection response, which carries the reason for rejecting the session establishment, and the reason is: rejecting the establishment of a session for the fourth identifier, or not allowing the establishment of a session for the fourth identifier.

[0124] In addition, the first communication device can also accept the second request according to the identifier-related information indicated in the first message. For example, when the first communication device is the AMF, the AMF receives the first message, which indicates to allow or consent to the second request corresponding to the fifth identifier, and the second request is a registration request or a registration update request. After the AMF receives the second request from the terminal, the second request carries the fifth identifier and is used for registration. Then, the AMF consents to the second request and performs a registration process for the fifth identifier associated with this terminal.

[0125] Similarly, the first communication device can also reject the second request according to the identifier-related information indicated in the first message. For example, when the first communication device is the AMF, the AMF receives the first message, which indicates not to allow or reject the registration request or registration update request corresponding to the sixth identifier. After the AMF receives the second request from the terminal, the second request carries the sixth identifier and is used for registration. Then, the AMF rejects the second request and rejects the registration request for the sixth identifier associated with this terminal. The reason for rejection is: not allowing this terminal or the sixth identifier to perform network registration.

[0126] In addition, the first communication device can also send a first request or a second request according to the first message. That is, after receiving the first message, the first communication device immediately sends a first request or a second request. For example, when the first communication device is the terminal, the terminal receives the first message, which indicates that the network side agrees to establish a PDU session for the seventh identifier under the first network. In this case, if the terminal accesses the first network, it can send a first request to the SMF. The first request is used to establish a session corresponding to the seventh identifier, and the SMF can consent to the first request, thereby establishing a PDU session for the seventh identifier associated with this terminal.

[0127] In one implementation, the first request may include at least one of the following:

[0128] PDU session establishment request;

[0129] PDU session modification request;

[0130] Quality of service (QoS) establishment or modification request;

[0131] Socket establishment request;

[0132] PDN connection establishment request;

[0133] Initial attach.

[0134] In addition, optionally, at least one of the first request and the second request is associated with an identifier. Here, the first request being associated with an identifier can be understood as: when using, logging in (on boarding), going online, activating, establishing, creating, or enabling the identifier, sending a request to establish a connection with a data network; similarly, the second request being associated with an identifier can be understood as, when using, logging in (on boarding), going online, activating, establishing, creating, or enabling the identifier, requesting services related to the identifier, such as registration.

[0135] It should be noted that the identifier associated with the first request and the identifier associated with the second request can be the same or different.

[0136] It should also be noted that in this application, for an identifier, the following actions can be performed on a communication device (such as a terminal or a network-side device): using, logging in, going online, activating, establishing, creating, registering, enabling an identifier; the content associated with the identifier can be understood as the configuration or parameters corresponding to the identifier when using, or logging in, or going online, or activating, or establishing, or creating, or registering, or enabling the identifier.

[0137] As can be seen from the above steps 201 to 203, in the embodiment of the present application, the first communication device can receive at least one of the first request and the second request, and receive the first message related to the identifier, so as to perform at least one of the following according to the first message: reject or accept or send the first request, reject or accept or send the second request. The identifier is used to identify or recognize at least one of a user and an application. The first request is used to request to establish a connection with a data network, and the second request is used to request an identifier-related service. It can be seen that in the embodiment of the present application, the following content can be indicated by the first message related to the identifier: whether the first communication device accepts at least one of the request to establish a connection with the data network and the request for an identifier-related service. In this way, when using the identifier of a certain user in network communication, it is possible to determine how to process at least one of the request to establish a connection with the data network and the request for an identifier-related service according to the content indicated by the first message (i.e., the related information of the identifier). It can be seen that the embodiment of the present application provides a solution for processing related network requests when using the identifier of a certain user in network communication.

[0138] Optionally, the first message includes at least one of the following items A-1 to A-3 (that is, the identifier-related information indicated by the first message includes at least one of the following items A-1 to A-3):

[0139] Item A-1: Identifier configuration, which is used to indicate at least one of the network configuration associated with the identifier and the restrictions on the object associated with the identifier;

[0140] Here, the network configuration associated with the identifier can be understood as, when using, or logging in, or going online, or activating, or establishing, or creating, or registering, or enabling an identifier, it is necessary to enable or disable the network configuration, or the corresponding network configuration to be used or not used. Or, it can also be understood that the network configuration associated with the identifier is used to indicate at least one of the allowed network configuration associated with the identifier and the disallowed network configuration associated with the identifier.

[0141] Here, the restrictions on the object associated with the identifier can be understood as the objects (such as applications, functions, networks, etc.) that the communication device is not allowed to use after using, or logging in, or going online, or activating, or establishing, or creating, or registering, or enabling an identifier. That is, after using an identifier for some objects, the object will be disabled, or prohibited from being used, or stopped being used. In this way, based on this restriction, at least one of the communication device and the identifier will be affected. For example, if the communication device is not allowed to use WLAN under a certain identifier, when the terminal accesses WLAN, it will go offline, deactivate, delete, and deregister the identifier.

[0142] In one implementation, the identifier-related information can be the terminal functions and network functions that can be used after using the identifier.

[0143] It should be noted that in this application, "login" can be understood as at least one of the following: use, go online, activate, establish, create, register, enable;

[0144] "Use" can be understood as at least one of the following: login, go online, activate, establish, create, register, enable;

[0145] "Logoff" can be understood as at least one of the following: not use, cancel, deactivate, delete, deregister, disable, close, etc.;

[0146] "Not use" can be understood as at least one of the following: logoff, cancel, deactivate, delete, deregister, disable, close, etc.

[0147] It should also be noted that the identifier configuration may include at least one of the network configuration associated with the identifier and the restrictions on the associated object.

[0148] Item A-2: The first information, which is used to indicate at least one of the relevant information of at least one communication device associated with the identifier and at least one identifier associated with the communication device;

[0149] Wherein, the fact that one identifier is associated with at least one communication device means that the communication device uses, or logs in, or goes online, or activates, or establishes, or creates, or registers, or enables the identifier; or it means that the identifier can be used, or logged in, or gone online, or activated, or established, or created, or registered, or enabled on at least one communication device. This standardizes on which communication devices the identifier can be used, and communication devices not specified are not allowed to use the identifier.

[0150] In addition, the same communication device can be associated with one or more identifiers, that is, the same communication device can use, or log in, or go online, or activate, or establish, or create, or register, or enable at least one identifier; the same identifier can be associated with one or more communication devices, that is, the same identifier can be used, or logged in, or gone online, or activated, or established, or created, or registered, or enabled on at least one communication device.

[0151] It should also be noted that the first information can be used to indicate at least one of the information of the communication devices associated with at least one identifier and the identifiers managed by at least one communication device.

[0152] It can be understood that the identifiers associated with the communication device can include the identifiers currently associated with the communication device, and can also include the identifiers historically associated with the communication device.

[0153] In one implementation, the terminal receives the first information. When the first information indicates that the identifier is associated with the current terminal, that is, the current terminal is allowed to use, log in, go online, activate, establish, create, register, or enable the identifier, the terminal sends the first request or the second request. When the first information indicates that the identifier is not associated with the current terminal, that is, the current terminal is not allowed to use, log in, go online, activate, establish, create, register, or enable the identifier, the terminal does not send the first request or the second request.

[0154] In one implementation, at least one of the AMF, the SMF, or the core network device receives the first information. The first information indicates that the identifier is associated with the first terminal, that is, the first terminal is allowed to use, log in, go online, activate, establish, create, register, or enable the identifier. Then, when the first terminal sends the first request (PDU session establishment or modification request) or the second request (registration request) to the AMF or the SMF, at least one of the AMF, the SMF, or the core network device agrees to the request, that is, allows the first terminal to use, log in, go online, activate, establish, create, register, or enable the identifier, or allows to establish or modify a session for the first terminal or the identifier. When the first information indicates that the identifier is not associated with the second terminal, that is, the second terminal is not allowed to use, log in, go online, activate, establish, create, register, or enable the identifier, at least one of the AMF, the SMF, or the core network device rejects the first request or the second request of the second terminal.

[0155] Item A-3: The second information, which is used to indicate at least one of the allowed identifiers and the disallowed identifiers;

[0156] Among them, an identifier cannot be used, logged in, gone online, activated, established, created, registered, or enabled on any communication device at will. It may only be allowed to be used, logged in, gone online, activated, established, created, registered, or enabled on a specific communication device. Therefore, the second information can be used to indicate at least one of the allowed identifiers and the disallowed identifiers.

[0157] Among them, the allowed identifier refers to the identifier that is allowed to be used, logged in, gone online, activated, established, created, registered, or enabled. Similarly, the disallowed identifier refers to the identifier that is not allowed to be used, logged in, gone online, activated, established, created, registered, or enabled.

[0158] It should be noted that the second information may correspond to the first communication device, that is, the second information can be used to indicate an identifier that allows the first communication device to use, log in, go online, activate, establish, create, register, or enable, or at least one of the identifiers that do not allow the first communication device to use, log in, go online, activate, establish, create, register, or enable.

[0159] It can be understood that the second information can also correspond to other communication devices other than the first communication device, that is, the second information can also indicate at least one of the identifiers that allow or do not allow other communication devices to use, log in, go online, activate, establish, create, register, or enable.

[0263] In one implementation, when the first terminal sends a first request (PDU session establishment or modification request) or a second request (registration request) to at least one of the AMF, SMF, or core network device, at least one of the AMF, SMF, or core network device rejects the request, that is, does not allow the first terminal to use, log in, go online, activate, establish, create, register, or enable the identifier, or does not allow to establish or modify a session for the first terminal or the identifier. The reason is:

[0264] The identifier (such as being used, going online, or logging in, etc.) exceeds the cumulative number of times.

[0265] The identifier (such as being used, going online, or logging in, etc.) exceeds the cumulative duration.

[0266] If at least one of the AMF, SMF, or core network device agrees to the request, that is, allows the first terminal to use, log in, go online, activate, establish, create, register, or enable the identifier, or allows to establish or modify a session for the first terminal or the identifier. The reason is:

[0267] The identifier (such as use, logging in, or signing in, etc.) has not exceeded the cumulative number of times;

[0268] The identifier (such as use, logging in, or signing in, etc.) has not exceeded the cumulative duration.

[0269] Optionally, before the first communication device receives the first message in step 202, the method further includes:

[0270] The first communication device sends a third request for requesting the first message;

[0271] Wherein, the third request carries at least one of the following F-1 to F-11:

[0272] Item F-1: The identifier of the first communication device;

[0273] Item F-2: The location information of the first communication device, such as the current location information of the first communication device;

[0274] Item F-3: DNN, such as the DNN subscribed to or used by the first communication device;

[0275] Item F-4: S-NSSAI, such as the S-NSSAI used by the first communication device;

[0276] Item F-5: Security key, such as the security key used by the first communication device (for verifying the identity of the first communication device);

[0277] Item F-6: The location information corresponding to the identifier, such as the location information when using, or logging in, or signing in, or activating, or establishing, or creating, or registering, or enabling the identifier;

[0278] Item F-7: The time information corresponding to the identifier, such as the time information when using, or logging in, or signing in, or activating, or establishing, or creating, or registering, or enabling the identifier, which can also be understood as the valid time information of the identifier;

[0279] Item F-8: Identifier, which can include one or more identifiers;

[0280] Item F-9: PLMN ID, such as the ID of the PLMN used when using, or logging in, or signing in, or activating, or establishing, or creating, or registering, or enabling the identifier;

[0281] Item F-10: Data Network Access Identifier (DNAI), such as the DNAI used when using, or logging in, or signing in, or activating, or establishing, or creating, or registering, or enabling the identifier;

[0282] Item F-11: Identification information of a subscription event; the subscription event may include the subscription events described in at least one of the foregoing Items J-1 to J-5.

[0283] In one implementation, the third request may be at least one of the following:

[0284] PDU session establishment request;

[0285] Registration request;

[0286] PDU session modification request;

[0287] PDN connection establishment request;

[0288] Uplink NAS message;

[0289] N2 message;

[0290] RRC message;

[0291] N1N2 message transfer (Namf_Communication_N1N2MessageTransfer);

[0292] Subscription data management (Nudm_SDM_Get);

[0293] Terminal policy control establishment request (Npcf_UEPolicyControl Create Request);

[0294] Terminal policy control update request (Npcf_UEPolicyControl Update Request);

[0295] Session policy control establishment response (Npcf_SMPolicyControl Create Request)

[0296] Session policy control update response (Npcf_SMPolicyControl Update Request).

[0297] Exemplarily, when the first message includes an identifier configuration, and the identifier configuration is used to indicate the network configuration associated with the identifier, the third request is used to request the network configuration associated with the identifier. In this case, the third request may carry at least one of the foregoing F-1 to F-7.

[0298] Exemplarily, when the first message includes an identifier configuration for indicating a restriction on an identifier-associated object, the third request is used to request the restriction on the identifier configuration-associated object. In this case, the third request may carry the above item F-8, that is, the third request is used to request the restriction on at least one identity-associated object.

[0299] Exemplarily, when the first message includes first information for indicating relevant information of at least one communication device associated with an identifier, the third request is used to request the relevant information of at least one communication device associated with the identifier. In this case, the third request may carry at least one of the above items F-3, F-6, F-8, F-9, and F-10.

[0300] Exemplarily, when the first message includes first information for indicating at least one identifier associated with a communication device, the third request is used to request the identifier associated with at least one communication device. In this case, the third request may carry at least one of the above items F-1, F-2, F-3, F-4, and F-9.

[0301] Exemplarily, when the first message is a notification corresponding to a subscribed event, the third request is used to request the notification of at least one identifier. In this case, the third request may carry at least one of the above items F-8 and F-11.

[0302] Optionally, the method further includes:

[0303] The first communication device sends the first message to at least one of the following:

[0304] A terminal, an operating system, an application layer, and at least one application. It can be seen that the first communication device can send the first message to at least one of the terminal, the operating system, the application layer, and at least one application, so that the object receiving the first message can determine whether to accept at least one of the above first request and second request according to the first message.

[0305] Wherein, the first communication device may be a terminal or a network-side device; the operating system may be the operating system of the terminal or the operating system of the network-side device; the application layer may be the application layer of the terminal or the application layer of the network-side device; and the at least one application may be an application installed on the terminal or an application installed on the network-side device.

[0306] Additionally, exemplarily, when the first message includes an identifier configuration for indicating a restriction on an identifier-associated object, the first communication device may send the restriction to the operating system, application layer, and at least one application of the terminal. Optionally, in this case, the at least one application includes all applications installed on the terminal, or the disabled applications corresponding to the identifiers associated with the restriction. Thus, for example, when the operating system of the terminal receives a request from an application to establish a socket connection, the terminal may determine, based on the restriction, whether to prohibit the application from establishing a socket connection under the identifier currently logged in on the terminal.

[0307] Optionally, the method further includes:

[0308] The first communication device starts a timer when a target condition is met, where the target condition includes at least one of rejecting the first request, rejecting the second request, receiving a rejection response corresponding to the first request, and receiving a rejection response corresponding to the second request;

[0309] After the timer expires, the first communication device sends at least one of the first request and the second request.

[0310] It can be seen therefrom that a timer can be configured for the first communication device to indicate that after at least one of the first request and the second request is rejected, the first communication device does not send at least one of the first request and the second request before the timer expires. That is, the timer is used by the first communication device to calculate the time for resending the first request or the second request, and only after the timer expires can the first request or the second request be resent again.

[0311] Optionally, the method further includes:

[0312] The first communication device sends indication information for indicating that the first communication device supports identifier capabilities.

[0313] Among them, the support for identifier capabilities means supporting identifier-related capabilities, such as supporting the identifier-related information described in items A-1 to A-4 above.

[0314] It can be seen therefrom that the first communication device can also send indication information to inform other communication devices that it supports identifier capabilities, that is, supports the use of identifiers.

[0315] In one implementation, the terminal has the ability to support identifiers and sends the first information to at least one of the following: the operating system, the application layer, the application, and the chip (modem).

[0316] In one implementation, a terminal capability is used to describe that the terminal can use or support an identifier, or the terminal supports functions, configurations, and services related to the identifier; a network element (or device) capability is used to describe that the network element can use or support an identifier, or the network element supports functions, configurations, and services related to the identifier.

[0317] In addition, in the case where the first message includes different contents, specific examples of step 202 described above can be as follows:

[0318] Example 1, in the case where the first message includes the second information (indicating at least one of allowed identifiers and disallowed identifiers), the first communication device determines to reject, accept, or send at least one of the first request and the second request according to the second information, including one of the following:

[0319] In the case where the first communication device determines, according to the second information, that the identifier associated with the target request is allowed, the first communication device accepts or sends the target request, where the target request includes at least one of the first request and the second request;

[0320] In the case where the first communication device determines, according to the second information, that the identifier associated with the target request is not allowed, the first communication device rejects the target request (for example, sends a response to the target request, where the response is used to indicate the rejection of the target request).

[0321] Example 2, in the case where the first message includes the identifier configuration, and the identifier configuration includes a network configuration associated with the identifier (including a network configuration associated with at least one of allowed identifiers and disallowed identifiers), the first communication device determines to reject, accept, or send at least one of the first request and the second request according to the network configuration associated with the identifier, including one of the following:

[0322] In the case where the first communication device determines, according to the network configuration associated with the identifier, that the current network configuration of the first communication device is allowed under the identifier associated with the target request, the first communication device accepts or sends the target request, where the target request includes at least one of the first request and the second request;

[0323] In the case where the first communication device determines, according to the network configuration associated with the identifier, that the current network configuration of the first communication device is not allowed under the identifier associated with the target request, the first communication device rejects the target request.

[0324] Example 3. When the first message includes the identifier configuration and the identifier configuration includes a restriction on the identifier associated object, the first communication device rejects, accepts, or sends at least one of the first request and the second request according to the restriction on the identifier associated object, including one of the following:

[0325] When the first communication device determines a restricted target object according to the restriction on the identifier associated object, the first communication device rejects the target request, where the target request includes at least one of the first request and the second request, and the target object includes the associated object of the identifier associated with the target request currently used by the first communication device;

[0326] When the first communication device determines that the target object is not restricted according to the restriction on the identifier associated object, the first communication device accepts or sends the target request.

[0327] Example 4. When the first message includes the first information (at least one of the information for indicating the relevant information of at least one communication device associated with the identifier and at least one of the identifiers associated with the communication device), the first communication device rejects, accepts, or sends at least one of the first request and the second request according to the first information, including one of the following:

[0328] When the first communication device determines that the identifier associated with the target request is not associated with the first communication device according to the first information, the first communication device rejects the first request, where the target request includes at least one of the first request and the second request;

[0329] When the first communication device determines that the identifier associated with the target request is associated with the first communication device according to the first information, the first communication device accepts or sends the target request.

[0330] It can be seen from this that the embodiments of the present application can receive or reject different requests according to the relevant information of the identifier. For example, when the above identifier for identifying a user is introduced, relevant function enhancements in the dimension of the identifier can be provided. For example: It is possible to allow a session to be established under a certain identifier and set QoS parameters; it is also possible not to allow a session to be established under a certain identifier and set QoS parameters. Exemplarily, if it is an identifier of a student status, the QoS can be improved when using teaching resources to ensure the teaching quality; or, if it is an identifier of an enterprise user, a specified enterprise slice can be used to ensure its communication quality, and so on.

[0331] An embodiment of the present application further provides an information processing method, which is applied to a second communication device. The second communication device may be a network-side device (such as an AMF or an SMF or a UDM). As Figure 3 shown, the information transmission method may include the following step 301:

[0332] Step 301: The second communication device sends a first message related to an identifier;

[0333] Wherein, the first message is used to indicate at least one of the following:

[0334] Reject or accept or send a first request, where the first request is used to request to establish a connection with a data network;

[0335] Reject or accept or send a second request, where the second request is used to request an identifier-related service.

[0336] In addition, after receiving the first message, the first communication device performs at least one of the following according to the first message:

[0337] Reject or accept or send a first request;

[0338] Reject or accept or send a second request.

[0339] In the present application, the identifier is used to identify or recognize at least one of a user and an application. Among them, the manifestation form of the user may be an account number or a digital identity, and the manifestation form of the application may be an application identifier. That is, the identifier realizes the identification, recognition, authentication, or verification of a person (human), or a real person, or a real user, or the identity of a real person by identifying the user.

[0340] Optionally, the identifier may include at least one of the following: user identifier, digital identity identifier, identity identifier, digital identifier, application identifier, account number, identity number, biometric information. It should be noted that the biometric information includes digital parameters such as fingerprints, irises, and faces; in different application scenarios or different application services, the identifiers of the same user may be different, but in the same application scenario or the same application service, the identifiers of different users are different; whether in the same application scenario or the same application service, the digital identity identifiers of the same user are different.

[0341] It should also be noted that the above first message is related to the identifier, which can be understood that the content indicated by the first message is related to the identifier, or the first message indicates the relevant information of the identifier.

[0342] As can be seen from step 301, the first message related to the identifier can indicate whether the first communication device accepts at least one of the above first request and second request; that is, it can be understood that: the first communication device can determine whether to accept at least one of the above first request and second request according to the identifier-related information indicated by the first message.

[0343] As can be seen from the above step 301, in the embodiment of the present application, the second communication device can send a first message related to the identifier, so that the first communication device performs at least one of the following according to the first message: rejecting or accepting or sending the first request, rejecting or accepting or sending the second request, where the identifier is used to identify or recognize at least one of a user and an application, the first request is used to request to establish a connection with a data network, and the second request is used to request an identifier-related service. It can be seen that in the embodiment of the present application, the following content can be indicated by the first message related to the identifier: whether the first communication device accepts at least one of the request to establish a connection with the data network and the request for an identifier-related service. In this way, when using the identifier of a certain user in network communication, it can be determined how to handle at least one of the request to establish a connection with the data network and the request for an identifier-related service according to the content indicated by the first message (i.e., the related information of the identifier). It can be seen that the embodiment of the present application provides a solution for handling related network requests when using the identifier of a certain user in network communication.

[0344] Optionally, the first message includes at least one of the following items A-1 to A-3 (that is, the identifier-related information indicated by the first message includes at least one of the following items A-1 to A-3):

[0345] Item A-1: Identifier configuration, which is used to indicate at least one of the network configuration associated with the identifier and the restrictions on the identifier-associated object;

[0346] Item A-2: First information, which is used to indicate at least one of the related information of at least one communication device associated with the identifier and at least one identifier associated with the communication device;

[0347] Item A-3: Second information, which is used to indicate at least one of the allowed identifiers and the disallowed identifiers.

[0348] It can be understood that the relevant descriptions of items A-1 to A-4 can be seen in the foregoing, and will not be elaborated here.

[0349] Optionally, in the above item A-1, the network configuration associated with the identifier includes at least one of the following items B-1 to B-7:

[0350] Item B-1: Data Network Name (DNN);

[0351] Item B-2: Single Network Slice Selection Assistance Information (S-NSSAI);

[0352] Item B-3: Public Land Mobile Network (PLMN) ID;

[0353] Item B-4: Location information;

[0354] Item B-5: Time information;

[0355] Item B-6: Maximum number of allowed identifiers (i.e., the maximum number of identifiers that a communication device is allowed to log in with);

[0356] Item B-7: Maximum number of allowed communication devices.

[0357] In one implementation, when the first terminal sends a first request (PDU session establishment or modification request) or a second request (registration request) to at least one of the AMF, SMF, or core network device, at least one of the AMF, SMF, or core network device rejects the request, that is, does not allow the first terminal to use, log in, go online, activate, establish, create, register, enable an identifier, or does not allow a session to be established or modified for the first terminal or the identifier. The reason is:

[0358] The number of identifiers associated with (used, gone online, or logged in, etc.) by the first terminal exceeds the maximum number of allowed identifiers. That is, the number of identifiers logged in or used by the first terminal exceeds the maximum number of identifiers, and the terminal is no longer allowed to log in or use identifiers.

[0359] In one implementation, when the first terminal sends a first request (PDU session establishment or modification request) or a second request (registration request) to at least one of the AMF, SMF, or core network device, at least one of the AMF, SMF, or core network device approves the request, that is, allows the first terminal to use, log in, go online, activate, establish, create, register, enable an identifier, or allows a session to be established or modified for the first terminal or the identifier. The reason is:

[0360] The number of identifiers associated with (used, gone online, or logged in, etc.) by the first terminal does not exceed the maximum number of allowed identifiers. That is, the number of identifiers logged in or used by the first terminal does not exceed the maximum number of identifiers.

[0361] In one implementation, when the first terminal sends a first request (PDU session establishment or modification request) or a second request (registration request) to at least one of the AMF, SMF, or core network device, at least one of the AMF, SMF, or core network device determines, based on the maximum allowed number of communication devices, that the number of all terminals currently using this identifier (i.e., the identifier associated with the first request or the second request) does not exceed the maximum allowed number of communication devices. Therefore, it agrees to this request, that is, it allows the first terminal to use, or log in, or go online, or activate, or establish, or create, or register, or enable the identifier, or allows to establish or modify a session for the first terminal or the identifier.

[0362] In one implementation, when the first terminal sends a first request (PDU session establishment or modification request) or a second request (registration request) to at least one of the AMF, SMF, or core network device, at least one of the AMF, SMF, or core network device determines, based on the maximum allowed number of communication devices, that all terminals currently using this identifier (i.e., the identifier associated with the first request or the second request) have exceeded the maximum allowed number of communication devices. Therefore, it does not agree to this request, that is, it rejects the first request or the second request, that is, it does not allow the first terminal to use, or log in, or go online, or activate, or establish, or create, or register, or enable the identifier, or does not allow to establish or modify a session for the first terminal or the identifier. The reason is that the number of communication devices for the current identifier (i.e., the communication devices logged in or using the identifier, such as terminals) has reached the maximum allowed number of communication devices. Therefore, the first request or the second request is rejected.

[0363] It can be understood that the relevant descriptions of items B-1 to B-7 can be referred to the foregoing, and will not be elaborated here.

[0364] Optionally, the restrictions on the identifier associated object include at least one of the following C-1 to C-6:

[0366] Item C-2: Restricted application;

[0367] Item C-3: Restricted request;

[0368] Item C-4: Restricted DNN;

[0369] Item C-5: Restricted network slice;

[0370] Item C-6: Restricted network.

[0371] It can be understood that the relevant descriptions of items C-1 to C-6 can be referred to the foregoing, and will not be elaborated here.

[0372] Optionally, the relevant information in the foregoing item A-2 includes at least one of the following items D-1 to D-4:

[0373] Item D-1: Communication device identifier associated with the identifier;

[0374] Item D-2: Duration corresponding to each communication device associated with the identifier;

[0375] Item D-3: Location information corresponding to each communication device associated with the identifier;

[0376] Item D-4: Function of the communication device associated with the identifier.

[0377] It can be understood that the relevant descriptions of items D-1 to D-4 can be referred to the foregoing, and will not be elaborated here.

[0378] Optionally, the first message is a notification corresponding to a subscription event.

[0379] Exemplarily, the notification includes at least one of the following items E-1 to E-5:

[0380] Item E-1: At least one identifier;

[0381] Item E-2: Communication device information associated with the identifier;

[0382] Item E-3: Number of times corresponding to the identifier;

[0383] Item E-4: Duration corresponding to the identifier;

[0384] Item E-5: Function corresponding to the identifier (i.e., the function of the communication device associated with the identifier).

[0385] It can be understood that the relevant descriptions of items E-1 to E-5 can be referred to the foregoing, and will not be elaborated here.

[0386] Optionally, before the second communication device sends the first message in step 301, the method further includes:

[0387] The second communication device receives a third request for requesting the first message;

[0388] Wherein, the third request carries at least one of the following items F-1 to F-11:

[0389] Item F-1: Identifier of the first communication device;

[0390] Item F-2: Location information of the first communication device;

[0391] Item F-3: DNN;

[0392] Item F-4: S-NSSAI;

[0393] Item F-5: Security key;

[0394] Item F-6: Location information corresponding to the identifier;

[0395] Item F-7: Time information corresponding to the identifier;

[0396] Item F-8: Identifier;

[0397] Item F-9: PLMN ID;

[0398] Item F-10: Data Network Access Identifier (DNAI);

[0399] Item F-11: Identification information of the subscribed event.

[0400] It can be understood that the relevant descriptions of Items F-1 to F-11 can be referred to the foregoing, and will not be elaborated here.

[0401] Optionally, the second communication device determines the first message according to at least one of the following H-1 to H-7:

[0402] Item H-1: Location information of the first communication device, such as the current location information of the first communication device;

[0403] Item H-2: DNN of the first communication device;

[0404] Item H-3: S-NSSAI of the first communication device;

[0405] Item H-4: DNAI of the first communication device;

[0406] Item H-5: Subscription information of the first communication device, which is used to indicate at least one of the permitted identifiers and the non-permitted identifiers associated with the identifier of the first communication device;

[0407] Item H-6: Second information, which is used to indicate at least one of the permitted identifiers and the non-permitted identifiers;

[0408] Item H-7: Time information corresponding to the identifier, such as the time information when using, or logging in, or going online, or activating, or establishing, or creating, or registering, or enabling the identifier, and can also be understood as the valid time information of the identifier.

[0409] In one implementation, the DNN, or S-NSSAI, etc. of the first communication device can be understood as the DNN, S-NSSAI, etc. that the first communication device is using or subscribed to.

[0410] Exemplarily, when the first message includes an identifier configuration for indicating a network configuration associated with the identifier, the network configuration associated with the identifier may be determined according to at least one of the above H-1 to H-7.

[0411] Optionally, when the identifier configuration includes a restriction on an identifier-associated object, the method further includes:

[0412] The second communication device receives at least one of the first request and the second request associated with the identifier;

[0413] The second communication device determines whether to accept at least one of the first request and the second request according to the restriction on the identifier-associated object.

[0414] The restriction on the identifier-associated object can be understood as a restriction on the application object (or the usage object) when using, logging in, going online, activating, establishing, creating, registering, or enabling the identifier. Therefore, if the second communication device receives at least one of the first request and the second request associated with the identifier, it can determine whether to accept at least one of the first request and the second request according to this restriction.

[0415] Optionally, the method further includes:

[0416] The second communication device receives at least one of the following:

[0417] A communication device identifier associated with the identifier;

[0418] Location information corresponding to the identifier (i.e., location information when using, logging in, going online, activating, establishing, creating, registering, or enabling the identifier);

[0419] Time information corresponding to the identifier (i.e., time information when using, logging in, going online, activating, establishing, creating, registering, or enabling the identifier).

[0420] Wherein, if a certain communication device uses, logs in, goes online, activates, establishes, creates, registers, or enables a certain identifier, it may send to the second communication device at least one of the identifier-associated communication device (i.e., this communication device) identifier, location information when using, logging in, going online, activating, establishing, creating, registering, or enabling the identifier, and time information when using, logging in, going online, activating, establishing, creating, registering, or enabling the identifier. In this way, the second communication device can count the communication devices associated with the same identifier and the identifiers associated with the same communication device.

[0421] In summary, taking the identifier described above as the user identifier as an example, the specific implementation of the information processing method according to the embodiments of the present application can be implemented as described in Embodiments 1 to 5 below:

[0422] Embodiment 1: The user identifiers (userIDs) that the sending terminal can use (i.e., allow) and disable (i.e., not allow), that is, the network side device sends a list of user identifiers that can log in or be prohibited from logging in to the terminal, so as to create a user ID list at the terminal; the specific process can be as Figure 4 shown, including the following steps 401 to 405:

[0423] Step 401: The terminal sends a request for obtaining the available or disabled user identifiers of this terminal; wherein, the request carries at least one of the following:

[0424] Terminal identifier;

[0425] Terminal's current location information;

[0426] DNN currently used by the terminal;

[0427] S-NSSAI currently used by the terminal;

[0428] Terminal's security key (credentials) (for verifying the identity of the terminal);

[0429] Location information of the terminal using the user identifier;

[0430] Time information of the terminal using the user identifier.

[0431] Step 402: The network side device determines the available user identifiers or disabled user identifiers of the terminal;

[0432] Among them, the network side device can determine the available user identifiers or disabled user identifiers of the terminal according to at least one of the following:

[0433] Terminal's current location information;

[0434] DNN currently used by the terminal;

[0435] S-NSSAI currently used by the terminal;

[0436] DNAI currently used by the terminal;

[0437] The subscription information of the terminal (the available user IDs and disabled user IDs bound to the terminal are given in the subscription information of the terminal)

[0438] List of available and disabled user IDs associated with the terminal identifier provided by AF;

[0439] Time window (i.e., the valid time period of the user identifier available to the user).

[0440] Step 403: The network-side device sends a list of user identifiers available to the terminal or disabled user identifiers to the terminal;

[0441] Among them, the network-side device can also send at least one of the following to the terminal:

[0442] The DNN corresponding to the available user identifier (i.e., the available user identifier is allowed to be used under this DNN);

[0443] The S-NSSAI corresponding to the available user identifier (i.e., the available user identifier is allowed to be used under this S-NSSAI);

[0444] The PLMN ID corresponding to the available user identifier (i.e., the available user identifier is allowed to be used under this PLMN);

[0445] The location information (Location) corresponding to the available user identifier (i.e., the available user identifier is allowed to be used at this location);

[0446] The Time window corresponding to the available user identifier (i.e., the available user identifier is allowed to be used within this Time window);

[0447] The DNN corresponding to the disabled user identifier (i.e., the available user identifier is prohibited from being used under this DNN);

[0448] The S-NSSAI corresponding to the disabled user identifier (i.e., the available user identifier is prohibited from being used under this S-NSSAI);

[0449] The PLMN ID corresponding to the disabled user identifier (i.e., the available user identifier is not prohibited from being used under this PLMN);

[0450] The Location corresponding to the disabled user identifier (i.e., the available user identifier is prohibited from being used at this location);

[0451] The Time window corresponding to the disabled user identifier (i.e., the disabled user identifier is prohibited from being used within this Time window);

[0452] The maximum number of user identifiers that can be logged in by a single terminal (used to limit the number of user identifiers used by a single terminal).

[0453] That is, the network-side device can send a list of available user identifiers or disabled user identifiers to the terminal, as well as at least one of DNN, S-NSSAI, PLMN, Location Time window that allows the use of the available user identifiers, and DNN, S-NSSAI, PLMN, Location Time window that does not allow the use of the disabled user identifiers.

[0454] Step 404: The terminal receives a service request from the APP. The service request is associated with a user identifier (for example, a session establishment request is associated with a user identifier), so as to select how to process the service request according to the saved list of available user identifiers or the list of disabled user identifiers; the service request can also be a socket establishment request.

[0455] Step 405: If the user identifier associated with the service request belongs to the disabled user identifier, the terminal sends a rejection message to the APP, and the reason for rejection is that the user identifier associated with the service request is disabled on this terminal.

[0456] It can be understood that if the user identifier associated with the service request belongs to the available user identifier, the terminal routes the service request to the AMF or SMF.

[0457] Optionally, the network-side device can also send a timer to the terminal, which is used to indicate that after the service request related to the user identifier sent by the terminal is rejected, the terminal will not send the service request corresponding to the user identifier to the network-side device before the timer expires (that is, after the timer times out, the terminal is allowed to send the service request associated with the disabled user identifier to the network-side device).

[0458] Optionally, the terminal can also declare the terminal capabilities to the network-side device to indicate that the terminal supports the use of user identifiers.

[0459] It should be noted that Figure 4 The main contents of each step in this embodiment are simply listed.

[0460] Embodiment 2: The network-side device sends the relevant restrictions of the user identifier to the terminal, and the specific process can be as Figure 5 shown, including the following steps 501 to 505:

[0461] Step 501: The terminal sends a request for requesting to obtain the restrictions of the user identifier-associated object to the network-side device; where the request carries the user identifier.

[0462] Step 502: The network-side device sends the restrictions corresponding to the user identifier carried in the above request to the terminal.

[0463] Among them, the restrictions on the user identifier associated object are used to indicate at least one of the following:

[0464] After a terminal logs in to a certain user identifier, reject the service requests of at least one disabled application APP;

[0465] After a terminal logs in to a certain user identifier, do not allow an IMS session to be established;

[0466] A specific network prohibited for a certain user identifier;

[0467] A specific network slice prohibited for a certain user identifier;

[0468] A specific DNN prohibited for a certain user identifier to access.

[0469] Step 503: After the terminal receives the restrictions corresponding to the above user identifier, it can send the restrictions corresponding to the user identifier to the terminal operating system, or the terminal application layer, or send them to the APP (for example, it can be sent to all the APPs installed on the terminal, or only sent to the disabled APPs under the corresponding user identifier);

[0470] Among them, when a session needs to be established, it can be controlled by the network-side device whether to allow the establishment, or it can be controlled by the terminal whether to allow the establishment;

[0471] For example, step 504: When the terminal triggers the establishment of a Protocol Data Unit (PDU) session (that is, when the terminal sends a session establishment request to the network-side device), the network-side device determines whether to reject the session establishment request according to the user identifier currently logged in by the terminal (that is, the user identifier associated with the session establishment request) and the restrictions corresponding to the above user identifier;

[0472] Among them, step 505: If at least one of the following is satisfied, reject the session establishment request:

[0473] The user identifier currently logged in by the terminal is not allowed to use the current DNN or S-NSSAI;

[0474] Under the user identifier currently logged in by the terminal, establishing an IMS voice session is prohibited.

[0475] Or for example, when the operating system of the terminal receives a session establishment request of an APP and needs to establish a socket connection, the terminal determines whether to establish a socket connection based on the restrictions corresponding to the above user identifier under the currently logged-in user identifier of the terminal. That is, if the APP is a disabled APP under the currently logged-in user identifier of the terminal, a socket connection is not established; if the APP is not a disabled APP under the currently logged-in user identifier of the terminal, a socket connection is established.

[0476] It should be noted that Figure 5 The main contents of each step in this embodiment are simply listed.

[0477] Example 3: Query the associated user identifier according to the terminal identifier. The specific process can be as Figure 6 shown, including the following steps 601 to 603:

[0478] Step 601: Each time a user identifier logs in or is used on a certain terminal, the second network side device records the relevant information of the terminal that logs in the user identifier, such as at least one of the identifier of the terminal, the terminal location, and the login or usage time information.

[0479] Optionally, the first network device (such as AMF or SMF) can send the above relevant information of the terminal that logs in the user identifier to the second network device (such as UDM).

[0480] Step 602: The first network side device sends a request for querying the information of the terminal associated with the user identifier (i.e., the logged-in or used terminal); where the request carries at least one of the following:

[0481] The user identifier to be queried (which can include one or more user identifiers);

[0482] The slice used by the user identifier to be queried;

[0483] The location information of interest (i.e., the location where the user identifier to be queried logs in or is used);

[0484] DNAI when logging in or using the user identifier to be queried;

[0485] PLMN ID when logging in or using the user identifier to be queried.

[0486] Step 603: The second network side device sends a response, and the response includes a terminal list, and the terminals in the terminal list all log in or use the user identifier carried in the above request.

[0487] It can be understood that, in one implementation, the response may further provide at least one of the historical terminal list for logging in or using the user identifier carried in the above request, the historical usage or login duration, and the historical login or usage location.

[0488] It should be noted that Figure 6 The main contents of each step in this implementation are briefly listed.

[0489] Embodiment 4: Query the associated user identifier according to the terminal identifier. The specific process can be as Figure 7 shown, including the following steps 701 to 703:

[0490] Step 701: Each time the user identifier logs in or is used on a certain terminal, the second network-side device records the relevant information of the terminal that logs in the user identifier, such as at least one of the identifier of the terminal, the terminal location, and the login or usage time information.

[0491] Optionally, the first network device (such as AMF or SMF) may send the above relevant information of the terminal that logs in the user identifier to the second network device (such as UDM).

[0492] Step 702: The first network-side device sends a request for reverse querying the user identifier associated with the terminal; wherein, the request may carry at least one of the following:

[0493] Terminal identifier;

[0494] Terminal location;

[0495] DNN used by the terminal;

[0496] S-NSSAI used by the terminal;

[0497] PLMN ID used by the terminal.

[0498] Step 703: The second network-side device sends a response, and the response includes the user identifier associated with the terminal identifier carried in the above request.

[0499] It should be noted that Figure 7 The main contents of each step in this implementation are briefly listed.

[0500] Embodiment 5: Subscribe to the relevant information of the user identifier. The specific process can be as Figure 8 shown, including the following steps 801 to 803:

[0501] Step 801: Each time a user identifier logs in or is used on a certain terminal, the second network-side device records the relevant information of the terminal that logs in the user identifier, such as at least one of the identifier of the terminal, the terminal location, and the login or usage time information.

[0502] Step 802: The first network-side device sends a subscription request, which carries the user identifier to be subscribed and the subscription event identifier (event ID) corresponding to the user identifier;

[0503] Step 803: The second network-side device sends a subscription response, which includes the subscription information of the subscription event corresponding to the user identifier carried in the subscription request.

[0504] Among them, the subscribable events corresponding to the user identifier include at least one of the following:

[0505] When the user identifier is used or logged in on a certain terminal, notify at least one of the terminal identifier, terminal location information, DNN used by the terminal, S-NSSAI, PLMN ID, IP address, and IP address segment;

[0506] The cumulative login times of the user identifier;

[0507] The cumulative usage duration of the user identifier;

[0508] Subscribe to the online or offline status of a certain user identifier;
