Mobile terminal and method of moving network thereof

A mobile terminal comprising:

• a first communication module configured to receive second network-associated information from a first network in an idle state with the first network and to output the received second network-associated information;
• a second communication module configured to set a receive-only mode with respect to a second network, to receive signal strength information of one or more neighbor cells belonging to the second network from the second network using the second network-associated information output from the first communication module, and to output the received signal strength information;
• and
• a controller configured to determine a target cell out of the one or more neighbor cells using the signal strength information output from the second communication module,
• wherein the second communication module moves from the first network to the second network as a data communication network using access information of the target cell included in the second network-associated information, under the control of the controller.

A communication control device comprising:

• a first communication module configured to set a link with a first network, to receive second network-associated information from the first network, and to output the received second network-associated information;
• a second communication module configured to set a receive-only mode with respect to a second network, to receive signal strength information of one or more neighbor cells belonging to the second network from the second network using the second network-associated information output from the first communication module, and to output the received signal strength information;
• and
• a controller configured to control a signal input/output operation between the first and second communication modules and a signal transmission/reception operation between the first communication module and the first network, and the second communication module and the second network, respectively,
• wherein the first communication module receives access information of a target cell from the first network according to transmission of the signal strength information output from the second communication module to the first network, and outputs the received access information of the target cell, and
• the second communication module moves from the first network to the second network as a data communication network using the access information of the target cell output from the first communication module.

A method of moving a network of a mobile terminal, the method comprising:

• receiving second network-associated information including information associated with one or more neighbor cells belonging to a second network from a first network in a link state with the first network;
• setting a receive-only mode with respect to the second network;
• receiving signal strength information of the one or more neighbor cells from the second network using the received second network-associated information, when the receive-only mode is set;
• transmitting the received signal strength information to the first network;
• receiving access information of a target cell out of the one or more neighbor cells from the first network;
• and
• moving from the first network to the second network as a data communication network using the received access information of the target cell.
