基于UML的计费网关的设计与实现

Design and implementation of charging gateway based on UML

计费网关是移动通信核心网络中的重要设备。它一般是集中式而且独立的网络设备,其主要负责采集来自各计费节点的计费数据,并且对计费数据进行过滤、合并、分发和传输等各项预处理,计费网关最终将计费数据提交给后续的计费系统进行批价处理。计费网关设备的引入大大简化了移动核心网络的拓扑结构,同时也减轻了计费系统的负载。

Charging gateway is an important device of mobile telecommunication core network, and generally it is a centralized and separate network device, and it is responsible for collecting charging data record from different charging nodes, as well as different pre- process to the received data such as filter, consolidation, distribution and transfer etc. And the charging data will be submitted to the billing system for the final billing. The network topological structure of the mobile telecommunication core network is simplified and the burden of the billing system is decreased.
