Abstract

This invention provides a wireless communication system wherein a network to which a mobile station should be handed over can be selected, using parametric data collected from network components other than the mobile station. Time taken for a handover between different types of network systems is reduced. The wireless communication system of the present invention comprises a mobile station equipped with multiple wireless interfaces, a server connected to a fixed network, and multiple access points. The mobile station determines available wireless interfaces and sends notification of the available interfaces' identifiers to the server. The server collects managerial data from network components and selects a wireless interface, based on the notification from the mobile station and the managerial data. The mobile station registers its locations in visiting networks corresponding to multiple available wireless interfaces with the server. The server retains the registrations of mobile station locations for the above wireless interfaces.
