"Extended Abstract Developing an IP-based mobility management scheme for next (3G and 4G) generation cellular environments is important to enable seamless integration with conventional IP-based data networks. By performing the location management functionality at the IP layer one can make the management scheme independent of the underlying link layer as well as (largely proprietary) physical layer technologies. This ensures that a uniform mobility management scheme can be deployed and maintained, even if the underlying layers are progressively upgraded. There are two key features that distinguish 3G/4G cellular architectures from currently deployed schemes:"
