PROBLEM TO BE SOLVED: To make an entry by a PHS communication apparatus without using an exclusive ID card by sending out a door opening command to open a prescribed door from a PHS base station when the PHS communication apparatus having a registered ID code is brought in a communication area of the PHS base station arranged in a building. SOLUTION: When a PHS communication apparatus 4 is brought in a communication area 5 of a PHS base station 1 arranged in a vicinity position of a door 3 arranged in the doorway of a building 2, a wireless ID code signal transmitted from the PHS communication apparatus 4 is received by the PHS base station 1. A received ID code is confirmed by the PHS base station 1, and a door opening command is sent out to an ID confirming control part 6 from the PHS base station 1. The ID confirming control part 6 arranged in a vicinal position of the PHS base station 1, opens the door 3 by sending out a control signal to open the door 3 to a door opening-closing device 7 according to a preset stored control program on the basis of this code confirming signal. |
