Abstract
In this paper, a method of vertical handover using SIP and Multi-Link Multi-Homing is proposed to select the wireless communication media in heterogeneous wireless network where 3.5G mobile phone system, WiMAX and Wireless LAN coexist. In this paper, when the mobile terminal move across the area of WLAN and WiMAX. Vertical handover is performed according to the network traffic. Proposed method is evaluated by using computer simulations.
