Patent ID: 8547882

Claim:
A mobile wireless communications control method for controlling transmission/reception periods of wireless communications among a plurality of wireless stations by using a Time Division Duplexing method, the mobile wireless communications control method comprising: obtaining time data from a group of GPS (Global Positioning System) satellites outside a wireless station; receiving a first signal frame including at least a first synchronization signal indicating a timing transmitted from another wireless station and first sub-data indicating a synchronization status of the another wireless station; generating a target synchronization signal according to one of the time data, the first synchronization signal obtained from the another wireless station and a second synchronization signal based on a self-propelled oscillation; storing second sub-data indicating a synchronization status of the wireless station itself; transmitting a second signal frame including the target synchronization signal and the second sub-data; initializing the target synchronization signal and the second sub-data of the wireless station itself when the time data are obtained in the time data obtaining; and updating the target synchronization signal and the second sub-data of the wireless station itself according to a result of comparing a weight of the first sub-data received from the another wireless station with a weight of the second sub-data of the wireless station itself; wherein the updating includes causing generating of the target synchronization signal according to the first synchronization signal obtained from the another wireless station and causing storing of the first sub-data received from the another wireless station when the weight of the first sub-data received from the another wireless station is equal to or less than the weight of the second sub-data of the wireless station itself.
