Abstract

PURPOSE: To improve operational convenience by totally setting the radio wave levels of respective base units and hand sets from an exchange and any specified hand set by matching those levels with actual zones. CONSTITUTION: A threshold value setting means 301 receives a radio wave level (threshold value) setting request signal transmitted from an exchange 10 and sets this level. Besides, the threshold value setting means 301 receives a threshold value setting request signal from a specified hand set 40 as well and decides the threshold value. Similarly, a threshold value setting means 401 sets the threshold values corresponding to the threshold value setting request signals from the exchange 10 and the hand set 40. Then, these set threshold values are stored in a threshold value storage means 101. At such a time, the threshold value setting request signal is transferred through any arbitrary idle channel inside a radio communication zone and further, the hand set 40 transmits the request signal in either a batch form or an interactive form. Therefore, since the radio wave levels of the respective base unit and hand set are matched with the actual zones, the levels can be totally set from the exchange and the hand set and operational convenience can be improved.
