Abstract
A method for setting up a dynamic group call includes the step () of selecting a group of radios () by a dynamic group call originator (). Once the radios that will be part of the dynamic group have been selected, the dynamic group call originator () transmits a dynamic group call message(s) to each of the selected radios. Each of the transmitted dynamic group call message(s) includes the IP address of one of the selected radios. Upon each of the target radios receiving their individually directed message, the target radios () can each send an optional acknowledgment message to the dynamic group call originator (). The originator () and the target radios () then switch to the dynamic talk group number assigned by the dynamic talk group message. Once the dynamic talk group call has been completed, the originator of the dynamic group call can send a dynamic group call disconnect message, which once received by the target radios () causes them to revert back to their previous operational state. Alternatively, instead of the dynamic talk group originator transmitting a disconnect message, the radio communication system controller () can transmit a disconnect message such as based on a timer (e.g., hangtimer, etc.).
