Abstract

With the continuous development of satellite communications, satellite communications have gone into the personal communication period, the corresponding location management strategy is particularly important in order to achieve hand-held terminal and personal communication globalization. In this paper, it is studied that the location management strategy for Fuxing low-orbit satellite communication system and proposes a two-layer database structure which includes the central database and the local database, and defines the location update and the location paging process as well as the detailed process design. At the same time, a paging optimization strategy based on the planning sequence algorithm is proposed for the subscriber stations with different speeds. As a result, the algorithm can reduce the paging signaling cost by 8% to 40% or so, to achieve the optimization effect. Finally, the corresponding influencing factors are analyzed according to the simulation results.
