Abstract
Systems and methods for a dispatch communication router are provided. The dispatch communication router allows calls between two or more dispatch communication networks which operate using different dispatch communication protocols. The dispatch communication router includes a protocol interworking function, a media control stack and a transcoding function. The dispatch communication router also includes a dispatch technology protocol stack for each different dispatch communication protocol supported by the router. The dispatch technology protocol stack converts dispatch communication signaling of a particular dispatch communication technology into a common protocol. The dispatch technology protocol stack can also convert dispatch communication media into a common dispatch communication media protocol and media format, or a separate transcoder can be provided to perform such conversion. The dispatch communication router of the present invention allows support of new dispatch communication technologies by adding a new dispatch technology protocol stack and communication coders (if necessary).
