METHOD AND SYSTEM FOR TRANSPORTING INFORMATION FROM RESPONDING POC CLIENTS USING TBCP MESSAGE THROUGH ESTABLISHED SIP SESSION OF POC NETWORK

摘要

Disclosed is a push-to-talk-over-cellular (PoC) service that transmits information on a group talk in a wireless connection section for operation in a mobile environment with a low traffic burden and higher efficiency. The PoC service transmits a PoC call request message of an originating PoC client to a terminating PoC server, receives a response message to the PoC call request message from a terminating PoC client, and receives a message including information of the terminating PoC client transmitting the response message, from an originating PoC server.
