APPARATUS FOR CONTROLLING HANDOVER BETWEEN HETEROGENEOUS NETWORKS, METHOD OF PERFORMING HANDOVER BETWEEN HETEROGENEOUS NETWORKS, AND MOBILE ROUTER
First Claim
1. A method of performing handover between heterogeneous networks in a mobile router managing a mobile network, comprising:
- determining whether a handover to a network employing a different method from a network to which the mobile router belongs is required based on information prestored in the mobile router, the network to which the mobile router belongs determined by current location information of the mobile router; and
performing the handover according to the result of the determination.

Abstract
Provided are an apparatus for controlling handover between heterogeneous networks, a method of performing handover between heterogeneous networks in a mobile router, and a mobile router. The method includes determining whether a handover to a network employing a different method from a network to which the mobile router belongs is required based on information prestored in the mobile router, the network to which the mobile router belongs determined by current location information of the mobile router and performing the handover according to the result of the determination. Mobility detection time can be reduced by applying the handover technique between wireless/satellite networks based on link trigger and location to a mobile router moving at high speed. Thus, service interruption can be prevented regardless of movement speed, even in a satellite shadow region such as a station.
