电信网计费系统安全问题研究

Research on Security of Telecommunication Accounting System

在电信网络不断演进与融合的背景下,计费系统的安全问题越来越突出。为此,根据计费系统的结构和功能,分析了计费系统安全涉及的内容。并针对计费系统的特点,依据国际电信联盟提出的技术标准,提炼出一套安全保障措施。最后对计费系统的安全性研究进行了展望。

Accounting system is one of the most important parts of telecommunication network. With the development of the telecommunication network, many new technologies are applying in the system. And with many outside entities have to communicate with accounting system, the interface between them has become more and more complicated. The vulnerability of the accounting system is turning out markedly. In this background, this paper is going to study the security concerns in the accounting system. And according to the standards of ITU （International Telecommunication Union）, general methods have been summarized to solve these security problems.
