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.
