摘要： A mobile communication system that can obtain mobile station location information repeatedly at short intervals, without depending on whether base stations are synchronous or asynchronous, with lower loads and suppressed use of radio resources. For obtaining location information, a mobile station receives a paging channel periodically sent from a base station (Step 100), obtains the contents and the reception timing of this paging channel. Further, if it is necessary to obtain the transmission timing of the paging channel, that transmission timing is obtained (Steps 105, 106). The propagation delay of the paging channel or propagation delay differences between a plurality of periodic paging channels are calculated from the transmission timing and the reception timing of the paging channel (Step 107). The mobile station location information is calculated from the propagation delay or propagation delay difference, and outputted (Steps 108, 109, 110).

摘要： A wireless communication system comprises a relay system including a plurality of relay devices and a plurality of wireless terminal devices. Each relay device transmits control information to the wireless terminal device which is registered in the own relay device, and each wireless terminal device selects, based on the control information received from the relay device which registers the own wireless terminal device, a channel which is currently able to relay a communication among channels respectively allocated to the relay devices to establish a communication between the wireless terminal devices. Each relay device acquires information configuring the control information via a communication line and causes a downlink signal wirelessly transmitted by the own relay device to synchronize with a communication signal, and each wireless terminal device maintains, when shifting a channel for communication to another channel, a synchronized state established in a channel prior to shifting.
