In existing trunked systems, there are mecha- nisms which allow an individual subscriber to determine if other subscribers are currently affiliated on a system. These methods require that the user know the individual ID of the subscriber. These methods also require additional keypad manipulation to determine affiliation before making the call. This extra work is time consuming and inefficient. There does not exist any automated way to provide a subscriber unit with affiliation notifica- tion about another subscriber unit. Many users avoid this problem by transmitting messages inquiring if other users are affiliated and available. This wastes call resources, initiating user's time, and remaining talk group members time. This invention will eliminate this unnecessary activity for a key list of subscribers.
