A METHOD, SYSTEM AND APPARATUS FOR OPTIMIZING ANCHORING IN VOICE CALL CONTINUITY

摘要

A method, system, voice call continuity anchoring optimizing functional entity and routing control entity are provided to optimize anchoring in Voice Call Continuity, by setting up the correlation between call anchoring processing and service processing that may influence call anchoring. The method comprises: step A, observing the service information for called user by Voice call continuity Anchoring Optimizing VAO functional entity, and step B, determining that the subscribed service for called user will influence the present call anchoring and optimizing anchoring. Using the method can associate call anchoring processing with service processing which may influence call anchoring, and optimize the anchoring processing.
