PROBLEM TO BE SOLVED: To improve line traffic efficiency by inhibiting hand-off to switch a base station to be connected in the state of fixing communication equipment for mobile object in a communication system for a mobile object. SOLUTION: A portable telephone set 10 is provided with a transmission circuit 22, a reception circuit 23, an AGC circuit 24 and a system control circuit (microcomputer) 31, and based on an output voltage Vgc of the AGC circuit, the intensity of a received electric field is detected. This portable telephone set is provided with a position detecting part 34 for detecting of the portable telephone set on a charging stand 40, a request sending means to react to the detection output of the placement detecting part can be realized with a software and the request of inhibiting the hand-off or canceling the inhibition is transmitted to the base station. On the side of base station, when the portable telephone set is placed on the charging stand, the communication through a control channel for hand-off is inhibited corresponding to this request and on the side of the portable telephone set, the intensity detection of the unwanted received electric field is stopped. This inhibition or cancel of inhibition can be displayed on a display 15 of the portable telephone set as well. |
