Abstract
In a two-way communication system made up of a portable communication device and a fixed communication device, the portable communication device includes a stasis/movement determining circuit configured to convert a change in position of the portable communication device into an electric signal, and to determine from the electric signal whether the portable communication device is in a moving state or a stationary state in which the portable communication device does not move for a set length of time. The communication system performs control in which a two-way communication circuit is suspended when the stationary state is detected and the portable communication device is outside the range of communication to and from the fixed communication device, and is activated when the moving state of the portable communication device is detected while the two-way communication circuit is suspended.
