Mobility management is an important aspect in LEO (low earth orbit) systems. In terrestrial wireless networks, the movement of the user triggers location updating and determines the paging scheme, while in LEO satellite systems, the location updating and paging is mainly based on the movement of satellite. Terrestrial location management techniques must be altered to fit the LEO systems. This paper introduces a modified movement-based location updating and paging scheme in LEO networks. In this scheme the meta-cell concept is proposed which includes two spot-beams of one satellite. First the location management scheme based on the architecture with meta-cell location area is presented. Then an analytical model is applied to formulate the cost of location updating and paging for the movement meta-cell based dynamic location updating scheme. The comparison of performance between the meta-cell architecture method and the conventional signal-spot-cell architecture method is provided to demonstrate the cost-effectiveness and robustness of the proposed scheme under various parameters. To reduce the impact of meta-cell architecture on the location paging cost, a forced location updating strategy is presented which is used in the cases that the meta-cell includes the two spot-beams from different satellites.
