Abstract

This paper is to propose a seamless connection control (SCC) scheme for service interworking between cdma2000 and WLAN by a method in which a terminal drives handover. We need a method to provide a service continuity without disconnect in spite of changes of access node according to mobility of terminal between different kinds of networks. This method requires a capability to change the connection of channel maintaining a state of data transmission. Our goal aims to develop a method to maintain a state of data transmission and a seamless changes of transmission channel by controlling channel change by mobile if signal satisfies critical condition having measured the strength of radio signal at mobile. Having applied mobile controlled soft handover that developed by using a system consisting of cdma2000, WLAN, and LAN to and compared it with existing hard handover method, we are going to present results thereof.
