Abstract

See full text

An enhanced push to talk (PTT) method, a network, and a PTT server provide floor control and media traffic optimization for push to talk over cellular (PoC). Specifically, multiple Session Initiation Protocol (SIP) sessions are contemplated between controlling and participating servers while only requiring a single Real Time Protocol (RTP) session for media and a single Real Time Control Protocol (RTCP) session for floor control. In the single RTP and RTCP session, the synchronization source identifier (SSRC) can be used to differentiate between users equipment (UEs) at the controlling and participating servers.
