Abstract

PURPOSE:To extend a service permission zone, by setting the squelch level to a value lower than the connection conditional squelch level during service. CONSTITUTION:During service, mobile station 10 moves in the arrow direction and goes over the range of the solid line and enters zone Z1'. Once the connection service state is set, squelch level l1 is automatically lowered previously to squelch level l2 of service permission. Further, the receiving range in level l2 becomes zone Z1'. The zone of service permission is extended more than Z1 and becomes Z1' shown by the dotted line, and service is held until the station goes over this zone.
