Terminal device capable to operate at a dual power feeding mode for supporting a dual-mode configuration having two different wireless communication modules
First Claim
1. 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, andwherein 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.

Abstract
An apparatus and method for controlling a terminal having two modules connected to a network at power feeding in dual modes. A first power supply feeds main electric power via a main current limiting unit to a first controller and a second controller. The first controller controls a first wireless communication unit using the main electric power and changes a connection state with a first network by checking a connection state of a sub-electric power and determining whether connection with a second network is accessible in accordance with a request for the connection with the second network. A second controller controls a second wireless communication unit for connection to the second network using the main electric power.

9. A method of controlling a terminal comprising at least two modules connected to a network in a dual power feeding mode, the method comprising:
-
determining whether main electric power is being fed from an electronic device; connecting to a first network in response to a request for connection thereto when the main electric power is being fed from the electronic device; determining whether connection to a second network is accessible when a request for connection with the second network is generated during the connection to the first network; and changing a connection state with the first network according to whether the sub-electric power is being fed from the electronic device when the connection with the second network is accessible, wherein a current of the main electric power or the sub-electric power fed from the electronic device is limited to a level where the function of the external electronic device is not restricted, and wherein when an insufficient amount of main electric power is being fed for operation, the terminal utilizes the dual power feeding mode of the electronic device to perform a handover and data communication in accordance with a received signal strength indicator (RSSI) of the network to which the user belongs. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
