Introducing a hybrid Fast and Hierarchical MIPv6 scheme in a UMTS-IP converged architecture

Abstract

IP technology will play a key role in beyond 3G systems, which face the great challenge of integration so as to provide seamless services 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, and on the support of fast handoff across UMTS access networks by means of a hybrid Fast and Hierarchical Mobile IPv6 (F/HMIPv6) proposal. Emphasis is also put on identifying the proper points of interaction between the F/HMIPv6 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.

DMAP-FR: Dynamic Mobility Anchor Points for Mobility, Service and Failure Recovery Management in Mobile IPv6 Systems

“…The number of subnets covered by a MAP domain is static in HMIPv6. This concept can be applied at multiple levels in a hierarchical manner [12,14] and can be combined with the use of fast handover (IETF RFC 5568) [5,8] utilizing forwarding pointers between the current and next subnets in a hybrid manner.…”

DMAP: integrated mobility and service management in mobile IPv6 systems

“…The mobility rate with which subnets are crossed by MNs can be high, causing a high signaling overhead for the MN to inform HA and CNs of the CoA address change. There have been approaches [2,7,10,12,13] proposed to mitigate this high volume of network signaling cost, including, most noticeably, IETF work-in-progress MIP Regional Registration (MIP-RR) [4], Hierarchical MIPv6 [10] and IDMP [7]. MIP-RR uses a Gateway Foreign Agent (GFA) to provide a regional CoA, which acts as a proxy for regional movement management to keep track of the MN's current CoA as long as the MN moves within a region, thereby reducing the network signaling cost when the MN moves within a region.…”

MAPs in HMIPv6 are statically configured and shared by all MNs in the system.…”
