Abstract: A service processing method and related devices are disclosed. The method includes: receiving, by a mobility management entity (MME), an access request message sent by a user equipment; obtaining, by the MME, indication information; and if the MME has been registered as a short message serving node and it is determined, according to the indication information, that the MME is no longer used as the short message serving node, sending, by the MME, a notification to a home subscriber server (HSS) so that the HSS cancels registration of the MME as the short message serving node.
Abstract translation: 公开了一种服务处理方法及相关装置。 该方法包括：由移动性管理实体（MME）接收由用户设备发送的接入请求消息; 由MME获取指示信息; 并且如果MME已经被注册为短消息服务节点，并且根据指示信息确定MME不再用作短消息服务节点，则由MME向本地用户发送通知 服务器（HSS），使得HSS取消作为短消息服务节点的MME的注册。

Abstract: An event report sending method in which a session management network element receives an event notification request from a policy control network element, where the event notification request includes an event identifier and a notification address for receiving an event report of an event report receiving network element, and where the event report receiving network element is an application function network element or a network exposure function network element. The session management network element sends, a first message comprising the event identifier and the notification address to a user plane network element, where the first message indicates to the user plane network element to send, to the notification address, a first event report corresponding to the event identifier. Thus, the network exposure function network element sends the received first event report to the application function network element, such that the application function network element obtains the event report.

Abstract: A communication method, an apparatus, and a system in which a first session management function entity determines, based on information of a terminal group, user plane function entities accessed by terminals in a terminal group, and the first session management function entity determines a target user plane function entity based on the user plane function entities, where the target user plane function entity is used to perform communication between terminals in the terminal group. According to the method, the terminals in the terminal group are redirected to a same user plane function entity, namely, the target user plane function entity, so that communication between the terminals in the terminal group is locally implemented in the target user plane function entity. This shortens a communication path, and reduces a communication latency.

Abstract: A method, a related apparatus, and a system for recovering a called service of a terminal are provided. The method includes: when a called request of a user terminal is received, querying an initial proxy-call session control function (P-CSCF) entity with which the user terminal currently registers; if it is detected that the initial P-CSCF is faulty, selecting an available P-CSCF and sending, to the available P-CSCF, a notification message that carries a redundancy identifier, where the redundancy identifier is used to instruct the available P-CSCF to trigger the user terminal to re-register with the P-CSCF; and when a registration complete message sent by the P-CSCF with which the user terminal re-registers is received, delivering the called request to the re-registered P-CSCF to bear a called service of the user terminal.

Abstract: A policy control method includes receiving, by a policy control network element, an update request message carrying information about a first mobility management network element from the first mobility management network element, updating, by the policy control network element according to the update request message, information about a second mobility management network element in information of a policy association corresponding to a terminal that is stored in the policy control network element to information about the first mobility management network element. The policy control network updates the information about the second mobility management network element in the information of the policy association to the information about the first mobility management network element instead of deleting the policy association and re-establishing a policy association with the first mobility management network element.

Abstract: A method, apparatus, and system for disaster recovery of an Internet Protocol (IP) Multimedia Subsystem (IMS), where the method includes: triggering a redundant Call Session Control Function (CSCF); obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. Hence, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.
