Abstract: The evolution of wireless access networks flat IP architecture implies a key-role for IP mobility management in providing the ubiquitous always-on network access services. In particular the connection-oriented transport services requires an optimized routing by gateway relocation during the user’s mobility. This paper proposes distributed co-located mobility and IP anchors in the core network to solve the problem of unnecessary long routes and delay. Session continuity in connection with user mobility also require for a single connection to be capable of using multiple network paths, the proposed architecture applied Multipath TCP (MPTCP) functions for the simultaneous exchange of IP traffic through the transient use of multiple distributed IP anchors. We describe the important call control flows being exchanged across the various network elements of the proposed architecture due to mobility of mobile nodes. It also provides an evaluation of MPTCP enabled IP mobility to show how it can be systematically exploited to gain session continuity.
