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.
Claims29
A method for interurban dispatch group calling comprising:
- receiving, by a call controlling dispatch controller (DC), a dispatch group call request targeting a talkgroup served remotely by at least one remote controlling DC and targeting at least one communication unit, wherein the at least one communication unit is a member of the talkgroup, wherein the dispatch group call request is received from an originating unit;
- sending, by the call controlling DC to the at least one remote controlling DC, a request for the at least one remote controlling DC to page members of the talkgroup that each of the at least one remote controlling DC serve;
- receiving, by the call controlling DC from a first remote controlling DC of the at least one remote controlling DC, an indication that at least one communication unit is available;
- and
- sending, by the call controlling DC to the first remote controlling DC, a request for the first remote controlling DC to initialize channel resources to support a dispatch group call.

A method for interurban dispatch group calling comprising:
- receiving, by a remote controlling dispatch controller (DC), a request for the remote controlling DC to page members of a talkgroup that the remote controlling DC serves, wherein the talkgroup is targeted by a dispatch group call request and wherein the talkgroup is served by a call controlling DC;
- sending, by the remote controlling DC to the call controlling DC, an indication that at least one communication unit is available;
- and
- receiving, from the call controlling DC, a request for the remote controlling DC to initialize channel resources to support the dispatch group call request.

A communication controller comprising:
- a network transceiver;
- and
- a processor adapted to perform, using the network transceiver,
- receiving a dispatch group call request targeting a talkgroup served remotely by at least one remote controlling DC and targeting at least one communication unit, wherein the at least one communication unit is a member of the talkgroup, wherein the dispatch group call request is received from an originating unit,
- sending to the at least one remote controlling DC a request for the at least one remote controlling DC to page members of the talkgroup that each of the at least one remote controlling DC serve,
- receiving from a first remote controlling DC of the at least one remote controlling DC an indication that at least one communication unit is available, and
- sending to the first remote controlling DC a request for the first remote controlling DC to initialize channel resources to support a dispatch group call.
