Abstract
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.
