Integrated mobility control mechanism in next generation network

This paper presents a seamless handover mechanism. First, we proposed a host based layer 2 handover mechanism. The proposed algorithm is based on the API defined in MIH (Media Independent Handover) standard. By distributing the key intelligence to the mobile terminal, control overhead in the network side can be reduced. The principle of our mechanism is to put intelligence in the mobile terminal while the transport and control function of the network remains simple. For the HO support in the wide area, we also proposed HO mechanism that uses L2, L3, and application level handover capability. The integrated HO algorithm is based on the host based L2 HO algorithm. By using the mobility server as the pre-authorization controller, we can achieve fast handover.
