<p>PROBLEM TO BE SOLVED: To decrease the failure rate of a software hand-off procedure by outputting a control signal with an amplitude larger than that of an audio signal when the control signal on a communication channel is inputted at the time of software hand-off. SOLUTION: At a channel control part 100, an encoding part 141 encodes a signal from a base station controller. An amplitude control part 142 amplifies and outputs the signal encoded by the encoding part 141. When the control signal on the communication channel is inputted at the time of software hand- off, a control signal detecting part 143 controls the amplitude control part 142 so as to output the control signal with the amplitude larger than that of the audio signal. A decoding part 144 decodes the encoded signal from terminal equipment. Thus, when the terminal equipment receives any abnormal signal from base station radio equipment, which does not relays communication, with large energy, call disconnection to disable the reception of the signal from base station radio equipment, which relays communication up to the moment, can be decreased.</p> |
