Abstract
A handover method and apparatus for a mobile terminal using location information in a network of heterogeneous systems are provided. The handover method uses service area map information provided by a location service server in a mobile communication network in which at least one or more heterogeneous wireless network systems are connected through a predetermined network and, includes: receiving service area map information transmitted from the location service server; the mobile terminal determining whether or not the location of the mobile terminal is within the service area map; and if it is determined that the mobile terminal is within the service area map, the wireless terminal selecting an accessible wireless network system and then activating a unit for communicating with a base station of the selected wireless network system. According to the method, a battery consumption problem that occurs by activating all modems when a wireless terminal, which is connected to a predetermined mobile communication system in an environment where a plurality of heterogeneous systems are overlapping each other, is searching for candidate systems in order to perform handover to a heterogeneou…
