Method for controlling session and server using the same

摘要

Disclosed is a method for masking media flows against a discovery procedure for inter-UE transfer. According to the method, when a Service Centralization and Continuity Application Server (SCC AS) establishes a session, an User Equipment (UE) is able to indicate to the network that some or all of the media flow composing a session are not discoverable from other UEs. Therefore, when the SCC AS receives the request for discovery for discovery of the ongoing session on any UE, the SCC AS identifies which media flows in the ongoing session of the UE are indicated as indiscoverable, and does not send information about theses media flows to the other UEs.

1. A method for controlling a session in a Service Centralization and Continuity Application Server (SCC AS) which controls the session being performed between at least one first terminal and a remote end, the method comprising:
receiving a session discovery request message for acquiring information related to the session being performed between the at least one first terminal and a remote end from a second terminal; filtering information of one or more media flows of the session based on information related to at least one of user related information or operator policy; transmitting a session discovery response message including information related to the media flows except for the filtered information of the one or more media flows to the second terminal; receiving a media transfer request for at least one media flow, selected by the second terminal, from among the media flows except for the filtered information of the one or more media flows; and performing media transfer of the at least one media flow, wherein the one or more media flows of the filtered information could not be transferred by the media transfer request.
