To obtain a receiver which recognizes whether or not the receiver is in a receptible state without intended confirmation by a carrier by informing the carrier of it when the radio terminal equipment moves from the service area to the outside of the area or vice versa.

Call control processing by a CPU 5 of a radio selective calling receiver is started at application of power, conducts synchronization establishment processing and receives a synchronizing signal sent from a base station to discriminate whether or not synchronization is established. In the case that the synchronization is established, a mark or the like denoting in-zone is displayed on a display section 9 to discriminate whether or not an in-zone alarm that is raised when the receiver moves to in-zone is set. When not set, an alarm is raised to discriminate whether or not a stop instruction is received. When a stop instruction is received, the alarm is stopped and an optional value N is set to a counter. The production of the alarm is concretely substantiated by sound from a speaker 7 or vibration by a vibrator 11 or the like.
