Abstract
To address the need to provide interurban dispatch services, embodiments supporting an interurban dispatch group call service are disclosed. Call control in the controlling network equipment (e.g., 110-131) manages the dispatch service in both the local urban area (101) and the remote urban areas (151). Call flow embodiments that enable this management of group call service across urban area boundaries are described in detail.
