Patent ID: 8787307

Claim:
A mobile terminal comprising: a first communication module configured to: set a link with a first network, receive information associated with a second network, and output the received information associated with the second network; a second communication module configured to: set a receive-only mode with respect to the second network when a strength of a signal of the first network is decreased to a predetermined level or lower, receive signal strength information corresponding to one or more neighbor cells in the second network by using the information associated with the second network, and output the received signal strength information; and a controller configured to: control a signal input/output operation between the first and second communication modules, control a first signal transmission/reception operation between the first communication module and the first network, and control a second signal transmission/reception operation between the second communication module and the second network, wherein the first communication module is further configured to: receive a connection release message that includes access information corresponding to a target cell in the first network in response to output of the signal strength information, the target cell determined by using the transmitted signal strength information, and output a network movement command including the access information in response to receiving the connection release message, wherein the second communication module is further configured to select the second network instead of the first network as a data communication network by using the access information, wherein selecting the second network is in response to the network movement command, and wherein the information associated with the second network comprises cell-reselection information including at least a neighbor cell list, a frequency or ID information of each of neighbor cells included in the neighbor cell list, or a frequency bandclass to which each of the neighbor cells included in the neighbor cell list belongs, wherein the first communication module is further configured to: receive primary information associated with the second network, the primary information including information associated with one or more cells included in a primary candidate group among cells in the second network; and receive secondary information associated with the second network, the secondary information including information associated with one or more cells included in a secondary candidate group among the one or more cells included in the primary candidate group, and wherein the second communication module is further configured to receive the signal strength information using the received secondary information.
