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.

Abstract: A typical multi-site trunked communication system (100) comprises communication units (110-116) that are arranged into talk groups, communication resources (106-109) distributed among communication sites, (102-105) and a communication resource allocator (101). In such a system, a methodology is incorporated that allows communication units (110-116) to override communication site busy conditions, where the communication site busy conditions prohibits placement of group calls until all communication sites (102105) have an available communication resource (106-109). The communication site busy condition may be overridden by a communication unit (110-116) by initiating a busy override signal. Once the busy override signal is initiated, the communication resource allocator (101) allocates, in each site (102-105), a communication resource (106-109) to the communication group of the requesting communication unit (110-116).

Abstract: A wireless communication device facilitated by a network controller and corresponding methods select a list of requested groups for affiliation from a list of associated groups. The list of requested groups is sent to a network infrastructure where it is processed according to a set of rules. A final list of groups for affiliation is made and the network infrastructure is configured to support the affiliated groups. The list of affiliated groups may also be sent to the wireless communication device.
