移动通信中一种新的位置查询方案及其性能仿真

Performance simulation of a new location searching scheme for mobile communications

移动用户的剧增和移动通信业务的发展,对位置管理提出了更高的要求,因此,在移动通信的结构中,设计一个有效的位置管理方案是十分必要的。回顾了针对PCS网络的4种已经存在的位置查询方案,并提出了一种新的查询方案。仿真结果表明,这种新的位置查询方案在性能上要优于4种旧方案。

The proliferation of mobile users and the development of mobile communication services had spurred higher request for location management. So it was highly desired to design an effective location management scheme in the structure of mobile communication. Four old location searching schemes for PCS were reviewed and a new scheme was proposed. Simulation results show that the proposed scheme performs better than the old four ones.
