RADIO COMMUNICATION SYSTEM USING PRIVATE PHS AND LOAD DISTRIBUTION METHOD THEREOF, PHS TERMINAL AND OPERATION METHOD THEREOF, AND OPERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To lighten a communication load which is able to cause a delay during termination, by circumventing the concentration of PHS terminals that belong to one radio base station.;SOLUTION: Each of a plurality of radio base stations confirms whether the number of PHS terminals belonging thereto lies within a preset range on receiving a position registration request signal from a PHS terminal, and transmits a position registration success signal, when the number of PHS terminals lies within the range or a position registration reject signal, when it is not. When a PHS terminal attempts to belong to one of the plurality of radio base stations, the PHS terminal transmits the position registration request signal to a radio base station, having the largest RSSI (received signal strength indicator) value among the plurality of radio base stations, based on the RRI values corresponding to strength of reception signals from the plurality of radio base stations, and transmits the position registration request signal to a radio base station which has a second largest RSSI value from among the plurality of radio base stations on receiving the position registration reject signal from the radio base station.;COPYRIGHT: (C)2010,JPO&INPIT
