Mobility Management (MM) is one of the main functions in mobile networks. It aims to track the User Equipment's (UEs) and to allow calls, other mobile phone services to be delivered to UEs. For any mobility protocol there are two separate problems to be solved. One is location management (or sometimes called reachability), which keeps track of the positions of a UE in the mobile network. The other one is handover management (or sometimes called session continuity), which makes it possible for a UE to continue its sessions while moving to another cell and changing its access point.
