Seamless Handoffs in IP-Based Mobile Communication Networks
- To provide seamless handoffs is an important task of cellular systems. A user of a real-time conversation on a mobile terminal should not notice when moving from one base station to another one. In this paper we address handoff procedures in a scenario where the radio access network is assumed to be IP-based, i.e., IP is used up to the base stations, and the mobile terminal runs a Mobile IP client. First we will motivate the need for differentiation of fast handoffs and seamless handoffs. Then we will survey some previously proposed micro-mobility extensions; thereby we will address the question of what degree of micro-mobility support is needed in the typical structure of a radio access network. The main part of this paper then discusses network-initiated/assisted handoffs in combination with Mobile IP. Here, we aim to bring together ideas of 2G/3G systems and of IP-based approaches.
