Abstract :
We describe the roaming service with mobile IP between public WLAN and cdma2000 1× Ev-Do design, and implemented. In terms of network configuration, the coverage of public WLAN network is overlapped with that of Ev-Do network. In this configuration, mobile terminal will decide the access system among the available systems. We propose the roaming method based on measuring the power of WLAN signal in hybrid network environments, and implement it. In order to confirm the effectiveness of our roaming method, we apply our proposed method to seamless roaming with VOD service and evaluate performance of data transmission.
