ABSTRACT:
An auto-response mechanism in a wireless device is switched to active only when the device is in motion and is switched to inactive when stationary. To achieve this function, the wireless device has a signal receiving part which detects and receives a signal of a waiting control channel, a control part which carries out frequency number control of a signal receiving part and a signal transmitting part, extracts received electrical field information and control channel information, and automatically completes the circuit when a call arrives. Also included is a received signal information memory part 11 which periodically stores the control channel information and the electrical field information, and a arrival signal mode memory 12 which stores the setting and cancellation of the auto-response mode. Additionally, the wireless device periodically reads information from the received signal information memory part 11, determines the condition of motion based on changes in this information, and based on said determination results, stores the setting and cancellation of the auto-response in the arrival signal mode memory part 12.
