First Claim
1. A method implemented by a satellite communications system, the method comprising:

receiving a request to instantiate a second talkgroup that is different than the first talkgroup from a communications device provisioned to participate in the second talkgroup; and
in response to receiving the request to instantiate the second talkgroup;
establishing a second talkgroup control channel for transmitting information related to the second talkgroup;
establishing one or more second talkgroup traffic channels for transmitting communications between communications devices provisioned to participate in the second talkgroup, andsupporting transmission, via the second talkgroup control channel, of information facilitating access to the one or more second talkgroup traffic channels by communications devices provisioned to participate in the second talkgroup.

Abstract
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.
