IEEE 802.11 Wireless LAN (WLAN) has been enthusiastically adopted in business offices, homes, and other spaces, for both public and private wireless local network connection. The users would like to deploy Voice IP (VoIP) and Video Phone based on Mobile IPv6 Protocol over Wireless LAN network. However, the frequent change in the mobile node's location causes evident signaling overhead, handover latency and packet loss, which in turn leads to the service degradation of real time traffic in Mobile IPv6. In this paper, we propose a scheme based on Wireless LAN by adding a new component called Handover Control Function (HCF) in MIPv6, which records all APs's MAC address, backend ARs' address and network prefix of those AP's. By the means that all Mobile Nodes (MNs) report periodically all AP's MAC address and signal strength information to HCF which MN can probe, HCF decides whether or which AP MN shall associate with and notifies MN about the new AP/AR's information, meanwhile, a bi-cast mechanism shall be applied to further improve handover performance by reducing the packet loss during handover.

“…The Always Best Connected (ABC) concept is considered as the vision behind vertical handover between heterogeneous access technologies (e.g., from UMTS to WLAN) [1] [2] [3] [4]. ABC has always been about multi-interface mobile nodes and multi-access networks in which the simultaneous use of access technologies is foreseen as a key feature of 4G.…”

Network-based Localized Mobility Management (NetLMM) is considered as the future solution for the IP mobility management confined within the access network, as well as a solution for inter-access system handover between 3GPP and non-3GPP. In this paper, we enhance NetLMM to support simultaneous use of radio interfaces in 4G environments consisting of multi-interface mobile nodes and heterogeneous access technologies. All issues on how to manage and to use multiple interfaces simultaneously in NetLMM are identified. We present necessary enhancements for the network attachment and network detachment processes. It is pointed out that IP tunneling is not suitable for simultaneous access in NetLMM. Consequently, a new tunneling method, which is based on Stream Control Transmission Protocol (SCTP) and its extensions, referred to as virtual SCTP tunneling, is proposed. We show that that the new tunneling method is advantageous to both mobile users and network operators with the consideration of two scenarios, load-balancing and wireless bandwidth aggregation. Some simulation results are also provided in this paper as an early estimation of the new tunneling method.
