Abstract
The present invention encompasses a method of providing communication service to members of a talkgroup in a radio communication system (100). A typical system (100) includes a plurality of communication units (116-122), a plurality of communication sites (106-112), and a central controller (114) that communication resources among the communication units (116-122). Upon receipt of a request for a talkgroup call from a communication unit, the central controller (114) grants the talkgroup call request for the first talkgroup. When the central controller (114) receives, during the first call, a talkgroup call request for the same talkgroup, the controller (114) agglomerates the two concurrent talkgroup calls, thereby providing communication service to all members of the talkgroup using a single communication resource.
