method and system for decision of the central kontrollservers

摘要

A method for determining a POC server performing Controlling Function may include: receiving, by a selecting unit, a session establishment request from a UE; and selecting, by a selecting unit, one POC server as a POC server performing the Controlling Function from a plurality of POC servers associated with the session establishment request; performing, by the POC server selected, a service. A system for determining a POC server performing Controlling Function includes a selecting unit, configured to receive a session establishment request from a UE; select one POC server as a POC server performing the Controlling Function from a plurality of POC servers associated with the session establishment request; and the POC server performing the Controlling Function, configured to receive the session establishment request and perform a Controlling Function for the session establishment request. In accordance with this solution, the POC server for performing Controlling Function can be selected flexibly according to actual applications, thereby improving the service success rate greatly, reducing the media traffic in the system and utilizing the network resource reasonably.
