Seamless mobility across IP networks using Mobile IP
The landscape of today's telecommunications portrays an amazing patchwork of heterogeneous networks, with very few and complex bridges between them. In this context, IP technology has emerged as a natural means of initiating network convergence and the All-IP paradigm has become the implicit assumption for most studies on the next generation architecture design. However, the real added value of such networks from the user's point of view will lie in offering seamless and transparent services through any kind of network. This can only be achieved with a global solution for mobility management and some believe it to be Mobile IP. The purpose of this paper is to describe how the EURESCOM project P1013 FIT-MIP has evaluated the use of Mobile IP acting as a mobility management protocol federating various access network technologies such as PSTN, Wireless LAN or General Packet Radio System. The use of Mobile IP as the enabler for inter-access technology handoffs will be the first step towards providing always-on access to IP applications (e.g., VoIP, VPN, mobile Internet).
