Selective Paging Schemes for LEO Satellite Network Based on Dynamic Location Area

摘要：

Location management is one of the key points of movement management in low orbit satellite. Comparing with static location area, dynamic location area can reduce the cost of movement management, which is determined by the characteristic of user movement. In fact, each user only keeps two counters, one is the distance moved and another is the time passed. A location update is performed when this counter exceeds a predefined threshold value. Selective paging strategy is an optimized one which can significantly reduce the paging cost and time delay. In this paper, we propose 3 different selective paging strategies and compare these strategies by analysis and simulation.
