首都移动通信事业的飞速发展,使得北京移动通信公司原有的脱机计费模式和主机终端式营业网络已不能满足需要,因此北京移动组建了新的计费及营业综合业务网。新的综合业务网是由分布于三元桥计费中心、八个交换机房、十几个营业厅的局域网以及连接其间的主用及备用的广域网链路组成,全网包括了多种型号的小型机、网络服务器和 PC,运行着HP-UX、Windows NT、Windows 98等操作系统,还包括路由器、交换机、集线器等网络设备,使用了 Ethernet、DDN、X.25等网络协议。整个网络节点分散,结构复杂,并且对于网络传输的实时性、存储数据的完整性、业务主机的运行状况等都有着很高的要求。北京移动的计费及营业综合系统的硬件平台采用了惠普公司的 HP 9000系列服务器(包括2台 V2200,2台 N4000,
The rapid development of mobile communications in Beijing has made Beijing Mobile’s original off-line billing model and host terminal-type business network unable to meet the demand.

The entire network nodes are scattered and complex in structure, and have high requirements for the real-time transmission of the network, the integrity of the stored data and the operation status of the service host. Beijing Mobile’s billing and business integrated hardware platform uses a Hewlett-Packard’s HP 9000 series of servers (including two V2200, two N4000,
