Mobility management is a core issue in IP/LEO satellite network related research. The LEO system consists of wide network of moving satellites providing connectivity to any place on the earth. It implies that the system must support numerous wireless connections under high-mobility conditions. Existing mobility management protocols like Mobile IP suppose that two types of identities, indicating a unique name and position in the network, are dynamically bound in each handover. However, in the IP/LEO system, handovers are mainly caused by fast moving satellites, not moving nodes. As a result, quite a few binding update requests are generated during a short period by the moving satellites; this makes mobility management difficult. In this paper, we propose a new mobility management method that separates binding updates from handovers by using geographical location of the nodes. We evaluate the proposed method and show its effectiveness.
