METHODS FOR ASSISTING MOBILE COMMUNICATION DEVICES IN CONNECTING TO AN ACCESS POINT (AP), AND MOBILE COMMUNICATION DEVICES AND BASE STATIONS USING THE SAME

摘要

A mobile communication device is provided with two wireless modules and a controller module. The first and second wireless modules perform wireless transmission and reception using a telecommunication technology and an SRW technology, respectively. The controller module receives distance information of one or more APs, or location information of the APs and the base station, from a base station via the wireless module, and determines a first distance from the mobile communication device to the base station according to an uplink timing adjustment received from the base station via the wireless module. Also, the controller module determines one or more second distances from the APs to the base station according to the received distance information or location information, and scans for the APs which have the corresponding second distances approximate to the first distance, to connect to one of the scanned APs via the second wireless module.
