Abstract: A method, apparatus, and system for disaster recovery of an IP Multimedia Subsystem (IMS) are provided. 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. With the present invention, 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: A method for analyzing a network transmission characteristic, includes: receiving, by an intermediate network element, a service packet sent by a first service network element through the intermediate network element to a second service network element, where the service packet carries a service stream identifier, service stream information, and a control rule, where the service stream identifier is used to identify a service stream, the service stream information is used to provide a parameter that is required during transmission characteristic analysis, and the control rule is used to determine a type of the transmission characteristic analysis; and determining, by the intermediate network element, the type of the transmission characteristic analysis according to the received control rule, and performing, according to the service stream information, the transmission characteristic analysis on the service stream identified by the service stream identifier in a network application.
