  • Method, device and system for temporarily selecting a timeslot
    Patent number: 8116284

The radio communication device has an assigned default timeslot for communicating with the talkgroup. The radio communication device determines if the default timeslot is available for the radio communication device to communicate with the talkgroup and searches for an available timeslot, when the default timeslot is unavailable. The radio communication device temporarily selects the available timeslot as a temporary selected group timeslot for the talkgroup.
