Abstract
System and method for efficiently managing communication channel assignments within talkgroups having dual mode communication units capable of operating on a first communication channel type and on a second communication channel type, and single mode communication units capable of operating only on the second communication channel type. If, at a base site, each of the communication units associated with a talkgroup is a dual mode communication unit, a call for that talkgroup is assigned to be broadcast using a channel of the first communication channel type. If, at least one of the communication units associated with the talkgroup at the base site is a single mode communication unit, the call for that talkgroup is assigned to a channel of the second communication channel type. As communication units roam between sites, channel assignments are continuously updated based on the types of communication units at each base site at any one time.
