PROCESSING METHOD, DEVICE AND SYSTEM FOR SRVCC REFER SERVICE

摘要

Disclosed are a processing method, device and system for a Single Radio Voice Call Continuity (SRVCC) Refer service. The method includes that: a Service Consistency and Continuity Application Server (SCC AS) receives a Refer request carrying the object session participator information of an Internet Protocol Multimedia Core Network Subsystem (IMS) session (S702); the SCC AS judges the relevance between the session identification in the Refer request and the session identification in the SCC AS based on the object session participator information, and changes the session identification in the Refer request to the session identification in the SCC AS on the basis of the relevance (S704). The present invention solves the problem in the art that all kinds of services using Refer may fail by reason that the SCC AS is unable to identify the session identification, thus improving the range of application of the Refer service, and enhancing the robustness and stability of the SRVCC system.
