Popis: IP technology will play a key role in beyond 3G systems, which face the great challenge of integration in order to provide seamless service to users anywhere and anytime. Apart from its natural role as a unifier, IP also comprises the main drive for network evolution towards all-IP network infrastructures. In this regard, we exploit IP as an enabler for the evolution of the UMTS packet-switched core network, eliminating its duality at user and transport level. We focus on mobility management in the core network, which is handled by pure IP mechanisms (Mobile IPv6, MIPv6), and on the support of fast handoff across UMTS access networks by means of the IETF’s Fast MIPv6 proposal. Emphasis is put on identifying the proper interaction points between the Fast MIPv6 operation and the UMTS-specific Serving Radio Network Subsystem (SRNS) relocation procedure in order to provide a seamless handoff service to the user while not compromising the network’s performance and scalability.
