摘要

A wireless parent device (CS) for relaying the call connection of a wireless child device (PS) to a control device (ME) comprises: a call connection control unit for controlling the call connection of the wireless child device (PS); and a position registration requesting unit which requests from the control device (ME) a position registration which maps the identification information of the wireless child device (PS) to the identification information of the wireless parent device (CS), wherein when a request for the handover from the wireless parent device (CS3) to the wireless parent device (CS4) is received from the wireless child device (PS) which performs a call connection via the wireless parent device (CS3), the call connection of the wireless child device (PS) is controlled so as to be carried out via the wireless parent device (CS4) and the wireless parent device (CS2); when the call connection via the wireless parent device (CS2) is carried out, the position registration is not requested from the control device (ME), and when the call connection via the wireless parent device (CS4) and the wireless parent device (CS2) is completed, the position registration is requested from the control device (ME).
