Therefore, it’s an important feature of 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 have some defects in handoff and route aspects. Thus, cellular IP protocol is proposed for routing of 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. In this paper, 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 network. Comparing to GSM cellular communication services, the major advantage of third generation wireless communication (3G) are more high speed of communication, providing packet data communication, mobile internet, and mobile multimedia data communication, etc. To approach these objectives, the problems of frequency band and system capacity need to be solved. Moreover, the mechanisms and strategies of the architecture of communication, mobile IP[1][2] and cellular IP[3] management, mobility management…etc need to be designed and find the optimal solutions. The major objective of this paper is to propose multi-tier wireless communication architecture based on cellular IP to support the service requirements of mobile Internet and mobile multimedia communication. Based on this architecture, there are some issues of research will be executed. How to satisfy the users’ requirement for mobile Internet through wireless communication? In the proposed architecture, we decrease the overhead of system management and improve the total effectiveness. We also offer a Soft-handoff method to improve Quality of Service and resource switching management to reduce data packet loss.
