The vision of ubiquitous and continuous communications for a mobile user entails several emerging mobility types, which pose new requirements, for location management. In this paper, we present an integrated approach for advanced location management towards supporting all kinds of mobility types. After a justification of our approach, we describe our architectural considerations on a uniform network architecture accommodating various mobility scenarios. We propose integrated mobility servers for Mobile IP and SIP (session initiation protocol) to take advantage of their complementary features in supporting mobility. We also discuss the two major tasks of location management: location updates and paging using optimised signalling to reduce overheads and delay.
