Mobility level management for 5G network

5G network architecture is actively discussed in 3GPP SA2 [6] where management of mobility level is one of the key study items. Mobility management of the previous generation defines seamless mobility for the always connected service without packet loss. 5G network designed to support the level of mobility based on the UE demands. This paper explains the mobility level management framework for the connected mode. Different levels of HO are defined. Architecture and control procedure to support multiple HO level is described.
