High data rates, wider coverage, and improved mobility are all now largely owing to wireless broadband technology, which is now being developed and deployed worldwide. As a means to this end, the 4G network, an amalgamation of several wireless technologies, is planned to allow seamless mobility. 4G networks will also be totally packet-switched systems based on the Internet Protocol (IP). Researchers are working to develop intelligent mobility management solutions that use IP-based technologies to enable global roaming among different access technologies in the 4G-Network. The integration of diverse networks is facilitated by the use of Mobile IPv6. Fast handover is critical for mobile networks, however the original Mobile IPv6 doesn't have this capability. There are a large number of research teams striving to create a consistent protocol that will make it easier for customers to move about freely. In this study, we identify and examine the various concerns and challenges associated to mobility management in 4G-networks.
