1. A mobile communication device, located in a cell coverage of a cellular-type base station, comprising:
a first wireless module performing wireless transmission and reception to and from the cellular-type base station using a telecommunication technology;
a second wireless module performing wireless transmission and reception using a Short Range Wireless (SRW) technology; and
a controller module receiving distance information of one or more Wireless Fidelity (WiFi) Access Points (APs) which provide a SRW service in the cell coverage, or location information of the Wi-Fi APs and the cellular-type base station, from the cellular-type base station via the first wireless module, determining a first distance from the mobile communication device to the cellular-type base station according to an uplink timing adjustment received from the base station via the first wireless module, determining one or more second distances from the Wi-Fi APs to the cellular-type base station according to the received distance information or location information, determining whether a respective difference between each of the second distances and the first distance is less than a threshold value, and scanning for only the Wi-Fi APs which have the corresponding differences less than the threshold value, to connect to one of the scanned Wi-Fi APs via the second wireless module.
