1. A method for providing presence notification for push-to-talk (PTT) chat group communications, the method comprising a server performing:

  • receiving, from a communication device of a first member of a PTT chat group, a session initiation message to start a session for the PTT chat group, wherein the PTT chat group comprises a plurality of PTT chat group members including the first member;

    responsive to receiving the session initiation message, generating a first event notification message that includes an indication that the PTT chat group is active;

    sending the first event notification message to communication devices of at least some of the other PTT chat group members; and

    wherein the session initiation message is received from the communication device of one of a subset of the plurality of PTT chat group members and wherein only members in the subset are authorized to start a session for the PTT chat group;

    associating a priority level with the PTT chat group, wherein the priority level indicates a priority of the PTT chat group relative to other PTT chat groups; and

    assigning the priority level to the session; and

    conveying the priority level to the other members of the PTT chat group, wherein the conveyed priority level acts as a trigger for the communication devices of the other members of the PTT chat group to auto-join the session.
