In order to reduce the registration frequency and the handoff latency in LEO satellite IP networks

a VMR-based handoff management scheme was presented.When the handoff happens

the VMR associated with user segment network’s MR decided whether to transfer itself and register with the MR’s home agent by the cost function.The VMR’s data structure

the handoff operation procedure and the cost function model were presented

and the proposed method’s numerical simulation was carried on.The simulation result indicates that the proposed scheme can realize the isolation between the handoff and the registration procedure and be used in the LEO satellite IP networks.
