METHOD TO FACILITATE DISTRIBUTION OF GROUP IDENTIFICATIONS FOR PUSH-TO-TALK GROUPS

摘要

A method is provided of distributing push-to-talk group identifiers. When the PTT group is created, the user terminal (20) for the group creator automatically generates and sends a group identification message containing the group identifier to the other group members. The user terminals (20) receiving the message recognize that it contains a PTT group identifier and execute and group list update process to add the new group to a locally stored group list (26) or contact list.
