  • Patent number: 9306991
    Abstract: 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.

  • Patent number: 9031598
    Abstract: A method for providing presence notification for PTT chat group communications includes a server receiving, from a communication device of a member of a chat group, a session initiation message to start a session for the PTT chat group. The session initiation message includes a member-selected priority. The server generates an event notification message that includes an indication that the chat group is active and has been assigned a priority, and sends the event notification message to communication devices of at least some of the other chat group members. Additionally, where a group priority has been assigned to the chat group, the group priority is assigned to the session. Otherwise, the member-selected priority is assigned to the session.
