Abstract

A wide area radio communication system may contain a central controller (Zone Controller), remote sites (such as 6809 sites or Intellirepeaters), and subscriber units (such as radios). In systems where subscriber unit roaming is not controlled by the lixed end (by the zone controller for example) but by the subscriber unit itself, it is usually assumed that loca- tion updates from different remote sites will be received in the order in which contact was made. Subscriber location information, also called alftlia- tion information, is updated by the central control- ler to reflect the location from which the last loca- tion update which was received.
