Title:
METHOD AND APPARATUS FOR COMMUNICATION IN COMMUNICATION SYSTEM SUPPORTING MULTI-TALKER MISSION CRITICAL PUSH-TO-TALK (MCPTT)
Document Type and Number:
WIPO Patent Application WO/2021/235868
Kind Code:
A1
Abstract:
In embodiment of present disclosure, a method and apparatus to exchange an SSRC value between a client and a server for implicit floor requests are disclosed. In one embodiment, the exchange of the SSRC value between the client and the server for implicit floor requests is being done with Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of Session Description Protocol (SDP). In another embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of SDP. In another embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit/Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in SSRC and FMTP media attribute of SDP.
