Abstract
From an unusable site, one or more communication units selects a usable site, thereby reducing missed communications. First, a manager determines ( ) that a site is unusable for a predetermined set of communication unit(s). The predetermined set of communication units may include one or more individual communication units or communication units that are affiliated with a particular talkgroup at a particular time. A zone controller ( ) identifies ( ) any communication units from the set that are registered at the unusable site. The zone controller sends ( ) a message to the identified units to assist them in leaving the site. The communication units search ( ) the near sites for usability and register ( ) at new usable sites. An algorithm is provided to stagger registration by communication units at usable sites.
