In one implementation, information specifying a geographic area for a talkgroup may be received. In addition, information specifying that the talkgroup is a “warm” talkgroup may be received. In response to the receipt of the information specifying that the talkgroup is a “warm” talkgroup, a satellite constellation may be controlled to continuously light up a control channel in the geographic area for the talkgroup. A request to instantiate the talkgroup via the control channel may be received. In response thereto, the satellite constellation may be controlled to continuously light up a traffic channel in the geographic area for the talkgroup. Subsequently, the talkgroup may be determined to be inactive. In response thereto, the satellite constellation may be controlled to stop continuously lighting up the traffic channel in the geographic area while continuing to continuously light up the control channel in the geographic area.
