CALLING CONTROL SYSTEM FOR MOBILE RADIO COMMUNICATION SYSTEM

PURPOSE:To provide the calling control system for reducing invalid calling and improving the probability of call incoming at a mobile radio communication system. CONSTITUTION:History information 33 of position registration is recorded for each radio terminal in a memory 30 inside an exchange and when there is call incoming, a calling area to perform calling is decided based on the position registration history information in the past of a terminal. When there is no response to calling from the radio terminal, corresponding to the conditions of a system side load, calling is performed again in all the calling areas. When there is no response to the calling in all the calling areas from the radio terminal, the radio terminal is registered out of the area, and calling to the same terminal is suppressed until fixed time passes.
