20120188982 | APPARATUS AND METHOD FOR SUPPORTING HANDOFF BETWEEN HETEROGENEOUS NETWORKS IN PORTABLE TERMINAL - A portable terminal is configured to support a handoff between heterogeneous networks. The portable terminal includes a first communication unit, a second communication, a coverage identifying unit, and a switching unit. The first communication unit communicates with a mobile communication network. The second communication unit communicates with a heterogeneous network. The coverage identifying unit identifies entry of the portable terminal into a heterogeneous network area while performing a call connection through the mobile communication network. The switching unit attempts call connection through the heterogeneous network while maintaining the call connection through the mobile communication network when the entry of the portable terminal into the heterogeneous network area is identified. When a response to the call connection through the heterogeneous network is received, the switching unit terminates the call connection through the mobile communication network and maintains the call connection through the heterogeneous network. | 2012-07-26 |
