ABSTRACT:
Network access delays are minimized by using affiliation messages to pre-establish communications in a wireless communication network (100). A controller (102), upon receiving an affiliation message from a first site (104), establishes connections between the first site and a second site (105), the connections being uniquely associated with a talkgroup/site affiliation indicated by the affiliation message. Additional sites can be added by modifying the connection to include the additional sites. Using a multicast SVC as the connection between the first and second site eliminates the need for a multicast server and its associated delays.
