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.
