[0061] In this embodiment, the information sent by the terminal to the first network in response to the request information and the sending of the first message in S202 may be two independent steps, and the network entities interacting between the two may be different.

[0062] Optionally, as an embodiment, the method further includes: the terminal sending a second message to the second network, the second message including third indication information, the third indication information being used to indicate at least one of: not allowing multiple users, not supporting the use of user identification to access the network, and not using the identification ID to access the network.

[0063] In this embodiment, for example, the terminal user deregisters the user ID, such as deregistering the user ID in the terminal UI. The terminal sends a second message to the core network, which helps the Policy Control Function (PCF) update the terminal's policy and restore the original terminal's policy.

[0064] Optionally, as an embodiment, the terminal uses second configuration information to access the second network; wherein the second configuration information is unrelated to the user, or unrelated to the user's identifier, or unrelated to any identifier ID.

[0089] FIG4 is a flow chart of a communication method according to an embodiment of the present application, which can be applied to the third network function. As shown in FIG4 , the method 400 includes the following steps.

[0090] S402: The third network function performs at least one of the following: 1) sending fifth indication information to the first network function, the fifth indication information including at least one of the following: second indication information, the second indication information being used to indicate at least one of whether the network supports or does not support multi-users, whether the terminal allows or does not allow multi-users, whether the identification ID is allowed or not allowed to be used, and whether the identification ID is allowed or not allowed to be used in the terminal; one or more configured identification Profile IDs; one or more identification IDs; the address of AAA-S; the first configuration information; 2) using at least one of the configuration information, Profile ID, and update indication to update the terminal-related information in the UDR.

[0091] The identification ID is used to identify a user User, and the user User refers to an application layer user of the terminal, or a user of the operating system, or a terminal user, or the user User has nothing to do with the SIM card or the information in the SIM card.

[0093] In this embodiment, the third network function sends fifth indication information to the first network function, where the third network function may be Unified Data Management (UDM), Network Exposure Function (NEF), Application Function (AF), etc., and the first network function may be AMF or SMF, etc. This embodiment corresponds to step 4 of the first embodiment below.

[0094] The third network function uses at least one of the configuration information, the Profile ID, and the update indication to update the terminal-related information in the UDR. This embodiment corresponds to steps 17-18 of the first embodiment below.

[0095] The communication method provided in the embodiment of the present application is conducive to different users using the same terminal with different configurations, thereby improving the utilization rate of the terminal and enhancing the user experience.

[0096] To illustrate the communication method provided in the embodiments of the present application in detail, several specific embodiments will be described below.

[0097] In the following embodiments, during the terminal registration process, the primary authentication (Primary Auth) is completed first, and then the User ID is authenticated. After the authentication is completed, the AF notifies the network of the replacement policy.

[0098] Example 1

[0099] This embodiment mainly introduces the registration-related process.

[0100] In this embodiment, UPM and AAA-P are optional network functions, or UPM and UDM are combined, or UPM and AAA-P are combined, or when there is no AAA-P, UPM and AAA-S are combined. As shown in Figure 5, this embodiment includes the following steps:

[0101] Step 1: The user uses the terminal UE as identified by the user identity (User ID), for example, by entering the user identity on the UE UI to replace the default user (the user identified by the SIM card information in the UE - called the terminal user) to use the terminal UE. The UE initiates a registration request to the core network, carrying the terminal user identity / terminal identity - hereinafter collectively referred to as the terminal identity, represented here by UE ID1, such as TMSI, IMSI, SUPI, SUCI, etc. It may also carry at least one of the following: the user identity (User ID) or information used to indicate the identity or information used to send to AAA-S, AAA-S addr or AF ID, and indication information 1 (for example, carrying a security-protected User ID when there is a security context, and carrying indication information 1 when there is no full context). The UE may include the User ID (indication information) or information communicated with the AAA-S in a container transparent to the AMF in the NAS message. The AMF only needs to forward it to the AAA-S.

[0102] Step 2: If the AMF does not have the corresponding UE context information, it uses UE ID1 or UE ID2 (such as IMSI, SUPI, SUCI) to request UE context information from the UDM, and may indicate the User ID or indication information 2 (indication, flag, etc.) to the UDM (which may be received from the terminal, or received from the terminal in the previous registration process, or received from step 4 or 21 in the previous registration process, or indication information obtained based on the aforementioned indication information - for example, the terminal indicates Multiple User Capable, or UDM returns Allowed Multiple User, then the AMF indicates Request User Info).

[0103] Step 3a: Optionally, the UDM initiates an authentication process with the UE and authenticates the terminal based on the UE ID (for example, an AKA authentication process based on a SIM card).

[0104] Step 3b: After step 2 (an embodiment where authentication is not required), or after step 3b, there are several possible embodiments:

[0105] A. Based on the received indication information 2 or User ID, the UDM indicates at least one of the User ID and the UE ID (possibly through the NEF), as well as the optional indication information 3, to the UPM (User Profile / Configuration Management Function).

[0106] Optionally, the UPM returns at least one of indication information 4, configuration ID (Profile ID), User ID (can be multiple), and AAA-S addr based on the User ID, User ID and UE ID, or indication information 3 and UE ID. Profile ID indicates user configuration information and can be multiple.

[0107] B. UDM receives instruction information 4:

[0108] Optionally, UDM obtains indication information 4, or obtains at least one of indication information 4, Profile ID (can be multiple), User ID (can be multiple), and AAA-S addr based on User ID, User ID and UE ID, or indication information 3 and UE ID.

[0109] The value of Profile ID may be User ID. Indication 4 may be used for at least one of the following:

[0110] 1) It is not related to the User ID and the UE ID, for example, it indicates to all terminals whether to allow or not allow the relevant function, that is, it indicates that the network does not support the relevant function.

[0111] 2) It is not related to the User ID but is related to the UE ID, for example, indicating whether the terminal allows or does not allow related functions.

[0112] 3) Related to the User ID but not to the UE ID, for example, indicating whether the User ID is allowed or not to be used on all terminals.

[0113] 4) Related to both the User ID and the UE ID, for example, indicating whether the User ID is allowed to be used on the terminal.

[0114] In the embodiment where the UPM and the UDM are jointly provided, step 3b is an internal process.

[0115] Step 4: After step 2 (an embodiment where no authentication is required), or after the authentication of step 3b is successful, the UDM returns the subscription information to the AMF, which may include at least one of indication information 4, Profile ID (can be multiple), User ID (can be multiple), and AAA-S addr.

[0116] Step 5: After step 1 or step 4 (after authentication is successful, or when no authentication is required), the AMF sends a registration accept message to the UE.

[0117] Step 6: Optionally, the AMF sends information for obtaining the ID and optional indication information 5 to the UE based on the information received from the UDM (which may be received in step 4 or in step 4 of the previous registration process) or based on the information received from the UE, such as a NAS message carrying the EAP ID Request message and the optional indication information 5, indicating the request for the User ID (instead of other IDs, such as UE ID, APP ID, etc.).

[0118] Step 7: After step 6, the UE sends information indicating the ID to the AMF, such as a NAS message carrying an EAP ID Response message, which carries the User ID. The UE may send the aforementioned Response message carrying the User ID based on indication information 5 in step 6 or based on the relevant information sent by the UE in step 1 (the AMF may not be able to or does not obtain the User ID in this step because it is contained in a container that is transparent to the AMF).

[0119] Steps 8-9: Based on the User ID received from the UDM, or based on the User ID received from the UE in step 1, or after executing step 7, the AMF sends an EAP ID Response message (received from the UE or generated based on the User ID) to the AAA-S (possibly via an AAA-P (Proxy AAA)) using the information used to indicate the identity obtained in step 1 or the information used to send to the AAA-S. The AAA-S addr is obtained from the terminal or the UDM. The EAP ID Response message carries the User ID (e.g., an AAA protocol message carrying the EAP ID Response message is sent via the AAA protocol). The AMF may also send to the AAA-S at least one of the following: Profile ID, User ID, UE ID3 (e.g., SUPI, GPSI, or MSISDN), Mapping ID for UE (which has a one-to-one mapping relationship with the UE ID (one Mapping ID for UE matches one UE ID, but not necessarily vice versa), or other ID information used for information exchange (e.g., Transaction ID, Session ID for information exchange), for example, carried in an AAA protocol message.

[0120] In an embodiment with AAA-P, the above-mentioned indication ID information, Profile ID, User ID, and UE ID3 are sent by the AMF to AAA-S by calling the authentication operation of AAA-P with this information as input parameters. Then, AAA-P sends the above-mentioned AAA protocol message to AAA-S to enable the AMF to send the above-mentioned information to AAA-S.

[0121] Steps 10-11: Optionally, AAA-S interacts with UPM (same as the interaction between UDM and UPM in step 3b) to obtain at least one of indication information 4, Profile ID (can be multiple), and User ID (can be multiple).

[0122] In the embodiment where UPM and AAA-S are jointly provided, this is an internal process.

[0123] In the embodiment where indication information 4 is obtained, if indication information 4 indicates that it is not allowed, the process directly jumps to step 17, and the AAA-S sends an EAP failure message.

[0124] AAA-S sends authentication information to AMF (or through AAA-P), as well as at least one of the optional Profile ID, User ID, and UE ID (UE ID1, UE ID2, UE ID3, and Mapping ID for UE are collectively referred to as UE ID in this document). For example, an AAA protocol message carrying an EAP message is sent through the AAA protocol. The AAA protocol message optionally includes Profile ID, User ID, and UE ID.

[0125] In an embodiment with AAA-P, AAA-P receives the above information sent by AAA-S and returns the above information for authentication, as well as optional Profile ID, User ID, and UE ID to the AMF.

[0126] Step 12: The AMF matches the UE ID based on the Profile ID or User ID and sends a NAS message for authentication to the corresponding UE. For example, the NAS message carries the received EAP message.

[0127] Step 13: The UE sends authentication information to the AMF, such as a NAS message carrying an EAP message.

[0128] Steps 14-15: Similar to steps 8-9, except that the information received from the UE for authentication is forwarded instead of being generated.

[0129] Step 16: Optionally, the AAA-S and the UE complete an authentication process based on the User ID.

[0130] Steps 17-18: The AAA-S sends information indicating the authentication result, and at least one of the optional Profile ID or Selected Profile ID, User ID, and UE ID to the AMF. For example, the information indicating the authentication result is an EAP success message or an EAP failure message, and the information indicating the authentication result, and the optional Profile ID, User ID, and UE ID are carried in an AAA protocol message.

[0131] Optionally, AAA-S notifies UPM of at least one of User ID, UE ID, and Profile ID, and UPM selects configuration information or a Profile ID related to the configuration information based on the information. When UPM and AAA-S are co-located, the aforementioned operation is internal.

[0132] The UPM uses at least one of the configuration information, Profile ID, and update indication to update the UE-related information in the UDR (possibly through the NEF). The UDR notifies the PCF, which then updates the UE's policy information. If there is an update indication, the PCF invalidates the old configuration, applies the new configuration, and notifies the UE of the updated information.

[0133] In an embodiment with AAA-P, AAA-S sends the above information to AMF through AAA-P (for example, AAA-S sends the above AAA protocol message, and AAA-P returns information indicating the authentication result to AMF, as well as optional Profile ID, User ID, and UE ID).

[0134] Step 19: The AMF matches the UE ID based on the Profile ID or User ID and forwards information indicating the authentication result to the corresponding UE, such as sending a NAS message carrying an EAP success message or an EAP failure message.

[0135] Optionally, the AMF sends at least one of the Profile ID and the User ID to the UE based on the authentication result, for example, through a NAS message.

[0136] Example 2

[0137] This embodiment mainly introduces the registration-related process, which is initiated by the UE. As shown in Figure 6, this embodiment includes the following steps:

[0138] Step 1: A user uses the UE as identified by a user identity (User ID). For example, by entering the User ID in the UE UI, the user replaces the default user (identified by the SIM card information in the UE, referred to as the terminal user). The UE sends a Registration Request (DN Request Container, [AAA-S address]) to the core network.

[0139] Step 2: If the AMF does not have the corresponding UE context information, it requests the UE context information from the UDM.

[0140] Step 3a: Optionally, the UDM initiates an authentication process with the UE and authenticates the terminal based on the UE ID (for example, an AKA authentication process based on a SIM card).

[0141] Step 3b: After step 2 (an embodiment where no authentication is required), or after authentication in step 3a is successful, the UDM returns a feature indication to indicate that the UE has subscribed to the service.

[0142] Step 4: After step 2 (in the embodiment where authentication is not required) or after step 3, the UDM returns subscription information to the AMF, including a feature indication, indicating that the UE has subscribed to the service. This indication can also be indicated by the AAA-S Address.

[0143] Steps 5-6: After step 1 or step 4 (after authentication is successful, or when authentication is not required), the AMF sends a DN Request Container and GPSI to the AAA-S based on the feature indication. In the case of AAA-P deployment, the DN Request Container, GPSI, and AAA-S addr are sent to the AAA-P, which forwards it to the AAA-S. Alternatively, the AAA-P can obtain the AAA-S address based on the User ID (NAI format - user-name@domain-name) in the DN Request Container.

[0144] Steps 7-8: AAA-S performs authorization based on GPSI and User ID. If authorization fails, execute steps 14-16.

[0145] AAA-S sends authentication information and GPSI to AMF (or through AAA-P).

[0146] Step 9: The AMF sends a NAS message for authentication to the corresponding UE, for example, the NAS message carries the received DN Request Container.

[0147] Step 10: The UE sends authentication information, such as a DN Request Container, to the AMF.

[0148] Steps 11-12: Same as steps 5-6.

[0149] Step 13: Optionally, the AAA-S and the UE complete an authentication process based on the User ID.

[0150] Steps 14-15: AAA-S sends GPSI, Profile ID, and information indicating the authentication result to AMF.

[0151] Step 16: AMF sends Registration Accept (Success / Failure) to the UE.

[0152] Step 17: AMF sends an update indication to PCF, carrying the Profile ID.

[0153] Step 18: Optionally, after successful authentication, the AAA-S selects a Profile ID based on the User ID and GPSI and sends the GPSI and Profile ID to the NEF. The NEF sends the SUPI and Profile ID to the UDR to update UE-related configuration information.

[0154] Step 19: The UDR notifies the PCF that the configuration has been updated.

[0155] Step 20: The PCF can learn about the new configuration based on the Profile ID, for example, from the UDR, or the UDR can notify the PCF of the new configuration information. The PCF uses the new configuration to generate a new policy. If the policy needs to be updated, the PCF notifies the UE, SMF, etc. of the new policy information.

[0156] Example 3

[0157] This embodiment mainly introduces the registration-related process, which is initiated by the network. As shown in Figure 6, this embodiment includes the following steps:

[0158] Step 1: The AF instructs the session to configure the service flow using a Profile ID or configuration information, which may include AAA-S address information. The Profile ID can be used to indicate the need for user identity authentication, and the AF indicates the need for user identity authentication. This information can be stored in the UDR via the NEF or UDM, which then notifies the PCF, or it can be sent directly to the PCF.

[0159] Step 2: The PCF notifies the AMF of the Profile ID, which also indicates that user authentication is required (the Profile ID can be generated by the PCF or indicated by the AF). AAA-S address information can be sent.

[0160] Step 3: The AMF sends a NAS message to the UE, indicating that the user identity needs to be authenticated, such as carrying an empty DN Request Container or a DN Request Container containing an EAP ID Request message.

[0161] Step 4: The UE sends a NAS message including the User ID, such as an EAP ID Response message carrying the User ID in the DN Request Container.

[0162] Step 5-6: The AMF sends the User ID to the AAA-S, for example, by sending the DN Request Container received from the UE.

[0163] Step 7: AAA-S and UE continue the User ID-based authentication process through AMF.

[0164] Step 8-9: AAA-S authenticates the User ID and sends an authentication result indication to the AMF.

[0165] Step 10: Based on the authentication result (e.g., successful authentication), the AMF sends an update request to the PCF and / or executes step 13. The update request carries the Profile ID.

[0166] Step 11: PCF generates corresponding policy information based on the Profile ID.

[0167] Step 12: The PCF responds to the AMF and sends policy information.

[0168] Step 13: AMF updates the policy to the UE using NAS message.

[0169] Example 4

[0170] This embodiment mainly introduces session-related processes, which are initiated by the UE.

[0171] This embodiment is similar to the first and second embodiments, except that it is triggered by a specific application using a specific user identity, resulting in the need to use the session configuration related to the specific user identity.

[0172] In the corresponding steps, the registration message can be a Service Request, PDU Session Establishment, or PDU Session Modification message, and the AMF can be an SMF. Other descriptions remain unchanged.

[0173] Example 5

[0174] This embodiment mainly introduces the session-related process, which is initiated by the network. As shown in FIG8 , this embodiment includes the following steps:

[0175] Step 1: The AF or P-CSCF instructs the session to configure a service flow using a profile ID or configuration information. AAA-S address information may be sent. The profile ID indicates that user identity authentication is required. The AF / P-CSCF indicates that user identity authentication is required. This information can be stored in the User Data Router (UDR) via the New Enterprise Environment (NEF) or User Data Manager (UDM), which then notifies the PCF. Alternatively, the information can be sent directly to the PCF.

[0176] Step 2: The PCF notifies the SMF of the Profile ID, which also indicates that user authentication is required (the Profile ID can be generated by the PCF or indicated by the AF). AAA-S address information can be sent.

[0177] Step 3: SMF sends SM NAS information to UE through AMF, indicating that the user identity needs to be authenticated, such as an SM PDU DN Request Container that carries an empty or EAP ID Request message.

[0178] Step 4: The UE sends a NAS message carrying SM NAS information, including the User ID, such as an EAP ID Response message containing the User ID in the SM PDU DN Request Container.

[0179] Step 5-6: SMF sends the User ID to AAA-S, such as sending the SM PDU DN Request Container received from the UE.

[0180] Step 7: AAA-S and UE continue the User ID-based authentication process through SMF.

[0181] Step 8-9: AAA-S authenticates the User ID and sends an authentication result indication to the SMF.

[0182] Step 10: Based on the authentication result (e.g., when the authentication is successful), the SMF sends an update request to the PCF and / or executes step 13. The update request carries the Profile ID.

[0183] Step 11: PCF generates corresponding policy information based on the Profile ID.

[0184] Step 12: PCF responds to SMF and sends policy information.

[0185] Steps 13-14: SMF and UE exchange PDU Session Modification Command related messages to complete the PDU session update process initiated by the network.
