Abstract: The present disclosure 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.

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 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.

Abstract: Embodiments of the present invention disclose a method, a network element, and a system for determining a target RAT. The method includes: receiving, by an access network element, access control information of a UE that is sent by a mobility management network element, where the access control information includes an identity of a PLMN and a radio access technology RAT allowed and/or a RAT not allowed by the PLMN; and determining, by the access network element, a target RAT for the UE according to the access control information. The present invention can be applied to a shared network environment.

Abstract: The embodiments of the present application provide a method for sending user subscription data, a method for receiving user subscription data, an HSS, and an SGSN. After receiving a request from an SGSN, the HSS determines whether the user subscription data includes CAMEL service data. If the user subscription data includes the CAMEL service data, the HSS sends the user subscription data to the SGSN by using a Gr interface, or sends non-CAMEL service data in the user subscription data by using the S6d interface and sends the CAMEL service data in the user subscription data by using a Gr interface to the SGSN.

Abstract: The present invention provides a method, a subscriber server and a mobility management entity for determining a serving node of a short message service. After receiving a location update request sent by an MME, an HSS/HLR determines services subscribed to by a subscriber. When determining that the subscriber has not subscribed to a CS domain service or there is only an SMS service in CS domain services subscribed to by the subscriber, the HSS/HLR registers the MME as a serving node that provides the SMS service for the subscriber.
