Patent ID: 8612778

Claim:
An apparatus for controlling a terminal comprising at least two modules connected to a network in a dual power feeding mode, the apparatus comprising: a first power supply for feeding main electric power to units of the terminal; a main current limiting unit coupled to said first power supply for limiting a current of the main electric power; a first controller coupled to the first power supply for controlling a first wireless communication unit using the main electric power fed from an electronic, determining whether connection with a second network is accessible in accordance with a request for connection with the second network, and changing a connection state with a first network according to whether sub-electric power is being fed from the electronic device when the connection with the second network is accessible; and a second controller coupled to the first power supply for controlling a second wireless communication unit for connection with the second network using the main electric power fed from the first power supply, wherein when an insufficient amount of main electric power is being fed for operation, the terminal utilizes the dual power feeding mode of the apparatus to perform a handover and data communication in accordance with a received signal strength indicator (RSSI) of a particular network to which the user belongs, and wherein the main current limiting unit limits the current of the main electric power or the sub-electric power fed from the electronic device, to the first controller and the second controller, to a level where the function of the external electronic device is not restricted.
