ABSTRACT:
A system and method for predefined dispatch talk group calls are provided. A first and second dispatch communication network use different dispatch station identifiers. Dispatch station identifiers in the format of the first network are stored in the dispatch communication server of the first network, dispatch station identifiers of the second network are stored in a dispatch communication server of the second network, and a group server of the second network includes a mapping of the dispatch station identifiers between the two networks. Providing the mapping of dispatch station identifiers in the second network allows predefined dispatch group calls between communication stations of different dispatch communication networks without requiring any changes to the addressing used in one of the dispatch communication networks.
