Abstract
A method and apparatus for joining a user to a call in a group communication network provides for receiving an indication from a user who wishes to initiate a group call and sending a request to a server to add the user to the group call if the group call is in progress. The method and apparatus also provides for receiving a response from the server indicating that the group call is in progress, alerting the user of being added to the group call, and receiving media from the server after a traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
