Abstract
A wireless mobile communication device comprises first and second wireless interfaces that are individually powered from a battery. A controller sets the first wireless interface in a power-ON state for establishing a first wireless link with a first base station, makes a determination whether a handover is necessary from the first base station to a second base station, sets the second wireless interface in a power-ON state in response to the determination that the handover is necessary for making a search for the second base station, and sets the first wireless interface in a power-OFF state when the second wireless interface has established a second wireless link with the second base station. A wireless LAN module is connected to the controller for establishing a session with a remote communication device via the first and second wireless links.
