<P>PROBLEM TO BE SOLVED: To provide means which is capable of associating an RTSP session ID with a SIP session ID without additional extension to SIP. <P>SOLUTION: An embodiment of the invention is a distribution server which comprises a communication control unit for receiving control communication path information from a terminal during a communication management session to establish a control communication path and a data communication path, and a storage unit for associating and storing a first session identifier identifying the communication management session with the received control communication path information. If the communication control unit further receives a stream control session establishment request including the control communication path information from the terminal via a control communication path established during the communication management session identified with the first session identifier, the communication control unit determines a second session identifier of a stream control session relating to the stream control session establishment request and stores, in the storage unit, the determined second session identifier by associating the second session identifier with the first session identifier associated with the received control communication path information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
