“…Both ideas are implemented in the mobile IP protocol (MIP) [3][4][5] by using home agents (HAs) and 'binding updates'. Improved solutions, such as hierarchical mobile IP (HMIP) [6], fast handovers in mobile IP (FMIP) [7], and flow-based fast handover for mobile IPv6 (FFHMIPv6) [8], also exist. However, all MIP-based solutions are inefficient in some way, with one or more of the following problems:…”

In this paper we discuss how we can use the session initiation protocol (SIP) to offer advanced services for mobile users over BT's 21st Century Network (21CN). We provide a brief overview of the advantages of using SIP and describe how SIP can play a vital role in today's and future heterogeneous networks, such as BT's 21CN. We demonstrate some advantages of using SIP for handover in these varied networks and we compare it against using other methods for handover, e.g. mobile IP.With the current and anticipated demand for users with multiple devices, we introduce the benefits of using SIP for personal mobility, including the concept of transferring sessions between a user's many and varied devices.We then consider quality of service issues that present themselves when moving frequently between varied, particularly wireless, networks with varying capabilities and congestion. We describe how we have used codec switching to cope with these adverse conditions, and consider the benefits of shifting the control of this adaptation to the network.This work centres on a custom-built test-bed together with our own real-time SIP-based videoconferencing application with codec switching capability. We present this test-bed, and results based on its use.

“…The handover delay of the original MIP reported in the literature lasts for several 100 milliseconds (ms) to several seconds [7,17,19]. Hsieh et al showed that by combining the extensions, the handover delay can be reduced to around 300 ms [7].…”

SHARE: seamless handover architecture for 3G-WLAN roaming environment

et al. 2007

For the transition from 3G communication systems to 4G communication systems, 3G-WLAN interworking systems can be a reference model for 4G communication systems. In this paper, we identify challenging problems in 3G-WLAN interworking systems and propose a loosely coupled architecture called SHARE. In SHARE, each WLAN hotspot access point (AP) is equipped with a 3G radio transmission module to generate radio signals for control channels of 3G networks in addition to a WLAN radio module. Consequently, base stations of the 3G networks share their control channels with hotspot APs. By monitoring these channels, mobile nodes can easily detect available WLAN hotspots without probe delay for handovers.

“…IETF also proposed MIPv6 for mobile users which have increased in recent years [2]. MIPv6 provides transparency in the routing of packets which are sent from correspondent nodes (CNs) to MN while a MN move from one network to another network (handover) by maintaining its home address [2]- [4]. The mobility in the MIPv6 only provides a good performance in the macro areas or non-real-time communication.…”

“…However, there are undesirable packet losses in the micro areas or realtime applications during handover time. These packet losses cause degradation in Quality of Service (QoS) for various applications such as VoIP [4].…”
