- 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

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.
