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).

Systems and method for a dispatch communication router

A system and method for translating dispatch communications between networks which operate according to different dispatch communication formats are provided. A communication system includes a dispatch translation network that translates dispatch communications between different dispatch communication networks. The dispatch translation network includes two or more dispatch translation gateways coupled to dispatch communication networks, the dispatch translation gateways perform signaling protocol and media translation for dispatch communications between the dispatch communication networks.

System and method for distributed dispatch translation gateways

A dispatch translation server (DTS) translates messages between a first dispatch communication network that uses a first protocol and a second dispatch communication network that uses a second protocol. The messages relate to the setting up of a dispatch communication session, controlling the channel floor of the dispatch communication session, and terminating the dispatch communication session. With regard to controlling the channel floor, dispatch translation server (DTS) translates messages when both the first and second dispatch communication networks use explicit floor control; when the first dispatch communication network uses implicit floor control and the sending party resides therein and the second dispatch communication network uses explicit floor control; when the first dispatch communication network uses explicit floor control and the sending party resides therein and the second dispatch communication network uses implicit floor control; and when both the first and second dispatch communication network use implicit floor control.
