Embodiment Construction

[0028] 1 through 7B in this patent document and the various embodiments used to describe the principles of the invention, detailed below, are by way of illustration only and should not be construed in any way as limiting the scope of the invention. Those skilled in the art should understand that the principles of the present invention may be implemented in any suitably modified wireless network.

[0029] In the following, the device and method for completing vertical handover in a multi-network wireless communication system according to the present invention are described. Although the content described below is to perform vertical handover between WLAN and broadband mobile network (eg, IEEE 802.16 system), the present invention can also be used for vertical handover between other networks.

[0030] FIG. 1 is a block diagram of a wireless communication system using a vertical handover scheme according to the present invention.

[0031] As shown in FIG. 1 , the wireless commun...

Abstract

Provided is an apparatus and method for performing a vertical handover in a multi-network wireless communication system. In a method for a vertical handover of a user terminal in a wireless communication system, a vertical handover control module selects a target network for a vertical handover using information about neighboring networks obtained from an information service server through an adaptation module. If the target network is different from a serving network, the vertical handover control module requests collection of target network information to a target network interface communicating with the target network through the adaptation module. The target network interface transmits the target network information collected in response to the information collection request to the vertical handover control module. The vertical handover control module determines a target base station using the collected target network information.
