We propose an efficient mobile multimedia communication protocol, mobile terminal software platform and mobile VoIP application for IP-based convergence networks. The proposed mobile multimedia communication protocol is called as ST-MRSVP (split tunnel based mobile resource reservation protocol) which integrates split tunnel based mobile IP and RSVP. Since mobile multimedia terminal platform should support seamless QoS level, mobile QoS modules for the terminal platform are developed and interworking together by means of internal communication method. A dedicated testbed is composed of a core-network embedding the proposed protocols and wireless LAN-based access networks. We verify functionality and performance of the proposed techniques by using various mobility experiments. As a result, the proposed architecture can reduce the handover delay time with seamless connectivity under 30% comparing with the standard mechanisms and support voice quality as good as CDMA phone
