Patent number: 8060092Abstract: An apparatus and method for enhanced heterogeneous network handover using a media independent handover scheme is provided. A heterogeneous network handover method of the present invention includes generating, at a mobile node, self-location information, transmitting the self-location information to a management server which manages heterogeneous networks, searching, at the management server, surrounding networks using the self-location information, composing a set of candidate networks including at least one of the surrounding networks, transmitting information on the set of candidate networks to mobile node and deciding, at the mobile node, a target handover network among the candidate networks. Accordingly, latency during handover in a heterogeneous network can be reduced.Type: GrantFiled: June 2, 2008Date of Patent: November 15, 2011Assignee: Samsung Electronics Co., Ltd.Inventor: Jong Yol Kim
