Application Layer Mobility Management Scheme for Wireless Internet

This paper discusses an application layer framework that uses a set of standard IETF protocols for supporting real-time and non-real-time multimedia applications on mobile terminals of next generation wireless [3G/4G] networks. It describes a 3G-IP architecture and brings out the requirements and issues which are essential for supporting roaming users in the wireless Internet in a ubiquitous way. In addition it highlights ways of achieving endto-end mobility by means of signaling instead of using any agent in the middle of the network as often done currently.
