A Study on an WiBro and WiFi Interworking Architecture design and performance analysis for Service Continuity

WiBro technology provide mobile devices with a transmission speed of more than 1 Mbps even under the condition of high mobility (120 km/h). In a building, however, there is more demand for high bandwidth for various activities, and WiBro services may not be available. In order to guaranteeing a seamless service continuity and high transmission capability for mobile users within a specific establishment that has deployed WiBro network, we should secure an internetworking platform for WiBro and WiFi networks. This paper introduces WiMax forum and 3GPP standards, proposes WiBro-WiFi Interworking (WWI) architecture, its implementation details, and finally verifies validity of the proposal by using OPNet simulations.
