Abstract
A method and apparatus for adding a member to an active call in a group communication network provides for receiving a member list from a user and sending a request to a server to add the member list to the active group cal l. The method and apparatus further provides for announcing each member in the member list that they are being added to the group call, receiving acknowledgement from a member who wishes to participate in the group call, a nd forwarding media to the member. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency b y exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
