    摘要： A method and an apparatus for determining an S-CSCF are provided, to avoid a problem that a target terminal fails to be registered or called when access to a data management device fails, thereby helping improve reliability of a communication system. In this application, the method includes: an I-CSCF determines that access to a data management device fails, and sends a first obtaining request to a first device; and the first device sends a first obtaining response to the I-CSCF based on the first obtaining request, where the first obtaining response may be used to indicate address information of a target S-CSCF, and the target S-CSCF is an S-CSCF with which a target terminal is registered. The first device may be the target S-CSCF or a backup device.

    摘要： A service control element stores a user filter criterion. When it receives a session request identifying the user, it checks whether the session request matches the user filter criterion, and outputs the session request to a defined service platform when the session request matches the user filter criterion. The element is arranged to retrieve, before forwarding the request to the service platform, a capability information element that indicates the dynamic capability of a user to utilize the service provided by the service platform. If the information element indicates that the user is not capable to utilize the service provided by the service platform, the session is terminated. Incoming messages can be appropriately managed already in the network element responsible for service control, and thus additional load and unnecessary charging considerations can be avoided.

    摘要： A Session Initiation Protocol (SIP) server within an Internet Protocol Multimedia Subsystem (IMS) network may be associated with multiple, different identifiers. In some embodiments, a process for implementing the multiple, different identifiers of the SIP server within the IMS network may include maintaining, at a home subscriber server (HSS), a first identifier of a Session Initiation Protocol (SIP) server in association with a user, and inserting a second identifier of the SIP server in a message header of a SIP request during a wireless communication session of the user. In some embodiments, the first identifier of the SIP server may be transmitted over Diameter (Cx) interfaces, while the second identifier of the SIP server may be transmitted over SIP (ISC) interfaces. Using multiple identifiers of a SIP server allows for minimizing downtime while restoring the user's wireless communication session in the event of a failure of the SIP server.

    摘要： Based on a method provided in the embodiments of the present invention, a control plane device sends an advertisement message to a forwarding plane device, and the forwarding plane device buffers the advertisement message and sends the buffered advertisement message to a host, thereby avoiding excessive signaling interactions between the control plane device and the forwarding plane device, so as to improve implementation efficiency of the control plane device and the forwarding plane device, and improve performance of the control plane device and the forwarding plane device.
