摘要： 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.

摘要： The present invention provides a method which includes: receiving a message, where the message carries a parameter indicating a validity period of a short message sent to a user or indication information indicating whether a record needs to be added to MWD of a user when a short message cannot be transmitted or fails to be transmitted; determining that the short message cannot be transmitted or the short message fails to be transmitted, and a value of the parameter is 0 or the indication information indicates that the record does not need to be added to the MWD of the user when the short message cannot be transmitted or fails to be transmitted; and skipping adding the record to the MWD of the user, where the record includes an identifier of a service center for short message service serving the user. According to the method, additional signaling interaction is reduced.

摘要： Embodiments of the present invention disclose a method, a related apparatus, and a system for recovering a called service of a terminal. 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.

摘要： A Serving Call Session Control Function (S-CSCF) receives a registration request message carrying an IMS Private User Identity (IMPI) and IMS Public User Identity (IMPU) pair. The S-CSCF determines: a lack of registration data corresponding to the IMPI and IMPU pair; and that the registration request message includes a reg-id parameter indicating that the registration request message relates to a multi-registration. The S-CSCF sends a Server Assignment Request (SAR) message to a Home Subscriber Server (HSS). The SAR message carries the IMPI and IMPU pair, a parameter for identifying that the SAR message relates to an initial registration of a user, and a multiple registration indication which indicates that the SAR message relates to a multi-registration associated with the IMPI and IMPU pair. The S-CSCF receives a Server Assignment Answer (SAA) message carrying registration backup data corresponding to the IMPI and IMPU pair from the HSS.

摘要： 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.

摘要： 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.
