Design and implementation of all IP architecture for beyond 3G system

The paper discusses the key technologies of an all IP architecture for a B3G mobile communication system. The aim is to contribute to the technical innovation of 3G systems by exploiting the potential of an IP-based B3G wireless communication system. The discussion focuses on the realization of an all IP core network. An all IP network architecture, improvement of end-to-end QoS, and flexible service provision are among the major challenges toward the B3G communication system. However, an all IP network architecture is the goal of the evolution of wireless networks on the way to the B3G system. The paper first reviews the development of the 3G core network, and proposes technologies for the all IP architecture for communication between 3G systems and the Internet, such as the assumed all IP network architecture and the design of protocol stacks. The paper describes the architecture of a protocol stack based B3G system, and then elaborates on the functionality of the MPPP, RLC, LLC and MAC layers. Finally, for fully supporting an all IP solution, the paper suggests further research work required based on the IPv6 core network.
