摘要
为了解决切换信息实时性以及数据库信息查询快捷性的问题,结合卫星星座通信系统的特点,提出了利用切换申请携带实时切换数据,并存入专门设置的切换数据寄存器的思想。解决了依赖位置管理数据库提供的非实时数据信息时,可能带来的反复交互问题,并且避免了相对繁琐的数据库查询过程,达到用很小的信令开销换取明显性能改善的目的。并从代价与效率入手,用仿真的方法验证了这种改进的切换数据登记策略的可行性、实时性与有效性。
In order to supply the real-time handoff information and quick inquiries in satellites constellations communication system, the strategy is put forward that collects the handoff information through the handoff requests and save them in the special handoff register. The strategy solves the possible repeated communication caused by the non-real-time location management database information, avoids the tedious database inquiry process, and brings obvious performance improvement with little cost. Taken into account of the cost and the efficiency, the simulation results demonstrate that the strategy is feasible, real-time and valid.
