在CDMA2000系統的研發過程中，發現了運行在CDMA2000核心網絡上的位置管理技術存在效率問題。該文在CDMA2000系統業務模型的基礎上，提出了一種優化技術，這種優化技術無需改變當前核心網絡的體系結構，但能大大提高用戶位置管理的效率，而且在現存的已初具規模的CDMA2000系統中，很容易通過軟件改造實現。

Abstract Location management scheme is very important in mobile communication system. During developing the CDMA2000 system, it is found that location management scheme of CDMA2000 core network works inefficiently. In this paper, an optimized scheme is proposed based on the service model of the current CDMA2000 system. Not changing the system structure of CDMA2000, this optimized scheme can work efficiently. At the same time, this scheme can be easily realized only via software alteration in the current CDMA2000 system.
