Description

Technical Field

[0001] The present disclosure relates to the field of wireless communications, and in particular to a method, device and system for updating user subscription data. Background Art

[0002] In the 3GPP standard, during the UE (User Equipment) registration process, AMF (Authentication Management Function) or SMF (Session Management Function) will subscribe to the user's contract data update notification from UDM (Unified Data Management). The message will carry the Callback URI (Uniform Resource Identifier) ​​of AMF and SMF. When the user's contract data changes, UDM will find the AMF and SMF according to the Callback URI information in the subscription message and send a notification message to them. In the scenario of AMF and SMF hot standby, when the main AMF fails or the main SMF fails, it cannot cancel the subscription to UDM. When the user's contract data is updated, UDM still sends notification messages to the original main AMF and SMF according to the Callback URI in the subscription message, resulting in notification failure. UDM is also unable to send notification messages to the backup AMF and backup SMF. Summary of the invention

[0041] Figure 1 The flowchart of some embodiments of the user subscription data update method disclosed in the present invention is shown in FIG. This embodiment is executed by a second network element, which is, for example, a UDM network element or a GMCF (Group Management Control Function) module, that is, a network element capable of storing user subscription data.

[0042] In step 110, a subscription message sent by an active first network element is received, wherein the subscription message includes identifiers of the active first network element and the standby first network element.

[0043] In some embodiments, the active first network element is an active AMF entity, and the standby first network element is a standby AMF entity.

[0044] In some embodiments, the active first network element is an active SMF entity, and the standby first network element is a standby SMF entity.

[0045] In some embodiments, the identifiers of the active first network element and the standby first network element are URIs.

[0046] In some embodiments, the active AMF entity sends a request message to the standby AMF entity to obtain the URI of the standby AMF, and after receiving the URI sent by the standby AMF entity, sends the URIs of the standby AMF entity and the active AMF entity to the UDM entity.

[0047] In some embodiments, the active SMF entity sends a request message to the standby SMF entity to obtain the URI of the standby SMF. After receiving the URI sent by the standby SMF entity, the URIs of the standby SMF entity and the active SMF entity are sent to the UDM entity.

[0048] In step 120, when the active first network element fails, the updated subscription data of the UE is sent to the standby first network element according to the identifier of the standby first network element.

[0049] In some embodiments, the second network element sends the UE's updated subscription data to the active first network element, wherein when the active first network element is sensed to have failed or no response message from the active first network element is received, the UE's updated subscription data is sent to the standby first network element.

[0050] In the above embodiment, the second network element can send the updated subscription data of the UE to the backup first network element according to the identifier of the backup first network element when the active first network element fails, thereby realizing real-time update of user policy.

[0054] In some embodiments, the active first network element is an active AMF entity, and the standby first network element is a standby AMF entity.

[0055] In some embodiments, the active first network element is an active SMF entity, and the standby first network element is a standby SMF entity.

[0057] In some embodiments, the active AMF entity sends a request message to the standby AMF entity to obtain the URI of the standby AMF, and after receiving the URI sent by the standby AMF entity, sends the URIs of the standby AMF entity and the active AMF entity to the UDM entity.

[0058] In some embodiments, the active SMF entity sends a request message to the standby SMF entity to obtain the URI of the standby SMF. After receiving the URI sent by the standby SMF entity, the URIs of the standby SMF entity and the active SMF entity are sent to the UDM entity.

[0059] In step 220, when the active first network element fails, the standby first network element receives the UE's updated subscription data sent by the second network element, wherein the second network element sends the UE's updated subscription data to the standby first network element according to the identifier of the standby first network element.

[0060] In some embodiments, the second network element sends the UE's updated subscription data to the active first network element, and upon sensing a failure of the active first network element or failing to receive a response message from the active first network element, sends the UE's updated subscription data to the standby first network element.

[0061] In the above embodiment, in the first network element hot standby scenario, when the active first network element fails, the second network element can successfully send a notification message to the standby first network element. The first network element can obtain updated user subscription data in a timely manner, so that a new user policy can be adopted to achieve real-time and accurate policy control of users.

In this embodiment, the first network element is an AMF entity as an example, the second network element is an UDM entity as an example, and multiple AMF entities constitute an AMF pool.

[0063] In step 310, the UE initially registers.

[0064] In step 320, the active AMF entity sends a request message to the standby AMF entity, requesting to obtain the Callback URI of the standby AMF entity.

[0065] In step 330, the standby AMF entity sends its Callback URI to the active AMF entity.

[0066] In step 340, the active AMF entity sends a subscription message to the UDM entity, and the subscription message carries the Callback URI of the active AMF entity and the standby AMF entity.

[0067] In some embodiments, the subscription message is Nudm_Subscriber Data Management_subscriberequest (Subscription Data Management-Subscription Request), and the Callback URI of the primary AMF entity and the backup AMF entity is reported in the parameter callback Reference.

[0068] In step 350, after the UE subscription data is updated, the UDM entity sends a notification message to the primary AMF entity, which carries the UE subscription data.

[0069] In some embodiments, Figure 4 As shown, the notification message is Nudm_SDM_Notification Request (User Data Management Notification Request).

[0070] In step 360, the UDM entity determines that the active AMF entity fails, and sends a notification message to the standby AMF entity, which carries the UE subscription data.

[0071] In some embodiments, the UDM entity determines that the active AMF entity fails based on the heartbeat message, or does not receive a reply message Nudm_SDM_Notification Response (User Data Management Notification Response) from the active AMF entity, then the UDM sends the message Nudm_SDM_Notification Request to the standby AMF entity.

[0072] After receiving the notification message, the standby AMF entity updates the stored user subscription data and replies to the UDM entity.

[0073] like Figure 4 As shown, the UDM entity sends a Nudm_SDM_Notification Response to the standby AMF entity.

[0074] In the above embodiment, in the AMF entity standby scenario, when the primary AMF entity fails, the UDM entity can successfully send a notification message to the standby AMF entity. The AMF entity can obtain updated user contract data in a timely manner, so that new user policies can be adopted to achieve real-time and accurate policy control of users. This embodiment realizes disaster recovery of user contract data updates.

[0076] In step 510, the UE sends a registration request to the RAN (Radio Access Network).

[0077] In step 520, the RAN sends a registration request to the primary AMF entity.

[0078] In step 530, security authentication (Authentication) / (Security) is completed.

[0079] In step 540, the active AMF entity sends a request to obtain a CallbackURI to the standby AMF entity.

[0080] In step 550, the standby AMF entity returns its own CallbackURI request to the active AMF entity.

[0081] In step 560, the UDM entity receives the UE registration request (Nudm_UECM_Registration, UE context management registration) sent by the primary AMF entity.

[0082] In step 570, the active AMF entity subscribes to user data (Nudm_SDM_Get) from the UDM entity and obtains a response from the UDM entity.

[0083] In step 580, the active AMF entity sends the CallbackURI of the active and standby AMF entities to the UDM entity.

[0084] In step 590, the primary AMF entity sends a registration response (Registration Accept) to the UE.

[0085] In the above embodiment, in the UE registration process, a message is added for the primary AMF entity to obtain the callback URI from the backup AMF entity, and the callback URI information of the backup AMF entity is added to the subscription message sent by the primary AMF entity to the UDM entity, so that the UDM obtains the URI information of the backup AMF entity. In the event that the primary AMF entity fails and fails to cancel the subscription, the UDM entity can send the user contract data update notification to the backup AMF entity to achieve real-time update of the user policy, thereby better controlling the UE policy.

[0090] In step 640, the active SMF entity sends a subscription message to the UDM entity, and the subscription message carries the Callback URIs of the active SMF entity and the standby SMF entity.

[0091] In some embodiments, the subscription message is Nudm_Subscriber Data Management_subscriberequest (Subscription Data Management-Subscription Request), and the Callback URI of the active SMF entity and the standby SMF entity is reported in the parameter callback Reference.

[0092] In step 650, after the UE subscription data is updated, the UDM entity sends a notification message to the active SMF entity, and the message carries the UE subscription data.

[0093] In some embodiments, Figure 4 As shown, the notification message is Nudm_SDM_Notification Request (User Data Management Notification Request).

[0094] In step 660, the UDM entity determines that the active SMF entity fails, and sends a notification message to the standby SMF entity, where the message carries the UE subscription data.

[0095] In some embodiments, the UDM entity determines that the active SMF entity fails based on the heartbeat message, or does not receive a reply message Nudm_SDM_Notification Response (User Data Management Notification Response) from the active SMF entity, then the UDM sends the message Nudm_SDM_Notification Request to the standby SMF entity.

[0096] After receiving the notification message, the standby SMF entity updates the stored user contract data and replies to the UDM entity.

[0097] like Figure 7 As shown, the UDM entity sends a Nudm_SDM_Notification Response to the standby SMF entity.

[0098] In the above embodiment, in the SMF entity standby scenario, when the main SMF entity fails, the UDM entity can successfully send a notification message to the standby SMF entity. The SMF entity can obtain updated user contract data in a timely manner, so that new user policies can be adopted to achieve real-time and accurate policy control of users. This embodiment realizes disaster recovery of user contract data updates.

[0100] In step 810, the UE sends a PDU session establishment request (PDU Session Establishment Request) to the AMF entity.

[0101] In step 820, the AMF entity sends a PDU session establishment SM context request (Nsmf_PDUSession_CreateSMContext Request) to the active and standby SMF entities.

[0102] In step 830, the active SMF entity obtains the CallbackURI of the standby SMF entity and sends the URIs of the active and standby SMF entities to the UDM, namely, Subscription retrieval / Subscription for updates.

[0103] In step 840, the SMF entity sends a PDU session create context response (Nsmf_PDUSession_CreateSMContext Response) to the AMF entity.

[0104] In step 850, PDU session authentication / authorization.

[0105] In step 860, the SMF entity communicates with the AMF entity to transfer information (Namf_Communication_N1N2Message Transfer).

[0106] In step 870, the AMF entity sends an N2 PDU Session Request to the RAN.

[0107] In step 880, the RAN sends a PDU session establishment success message (PDU Session EstablishmentAccept) to the UE.

[0108] In the above embodiment, in the UE registration process, a message is added for the primary SMF entity to obtain the callback URI from the backup SMF entity, and the callback URI information of the backup SMF entity is added to the subscription message sent by the primary SMF entity to the UDM entity, so that the UDM obtains the URI information of the backup SMF entity. In the case that the primary SMF entity fails and fails to cancel the subscription, the UDM entity can send the user contract data update notification to the backup SMF entity to realize the real-time update of the user policy, so as to better control the UE policy.
