Wireless communication that provides voice only is not sufficient to support users' needs. Therefore, it's important for next generation wireless communication to offer this capability through mobile Internet. Mobile IP allows mobile hosts to change their location and reduce data packet loss probability in wireless communication networks. However, mobile IP still has handoff and routing problems. Thus, the cellular IP protocol is proposed for routing IP diagrams to mobile stations and fast handoff control in a limited geographical area. It can cooperate with mobile IP to provide wide area mobility support. We offer a soft-handoff method to improve quality of service and resource switching management to reduce data packet loss for mobile multimedia communication in cellular IP and mobile IP networks.
