摘要:随着近年来我国电信业的迅猛发展，各项业务量快速增长，新的业务种类和新的服务形式不断推出，而旧的电信业务的计费处理从体制到技术都越来越不能适应形势的需要，甚至在某种程度上已经限制和阻碍了业务的发展。于是就出现了一些电信实时计费系统。

　　　本课题所要研究的模拟软件电信实时计费系统之预处理模块，就是一个基于电信实时计费系统的模拟软件。通过对这一课题的学习和研究，可以将电信计费系统预处理的基本原理、实现流程等通过模拟展现出来，并可作为对新的综合电信实时计费系统软件的一种探索来学习和研究，也可以顺带的了解整个电信实时计费的工作流程，具有一定的现实意义。

　本课题研究的内容由以下几个部分组成：

　系统定时地从交换机上下载新的中兴原始话单，放到对应的目录中去

　对原始话单进行码制转换

　对码制转换后的话单进行格式标准化

　对格式标准化后的话单进行号码规整

　对号码规整后的话单进行话单校验

　将正确的话单放入到正常话单文件中，将错误的话单放入到错误话单中去，并生成日志文件

关键字：码制转换,格式转换,号码规整,话单校验,电信实时计费系统

Abstract:Recent years, With the rapid development of China's telecommunications industry, business volume has achieved rapid growth , new types of business and new service forms have come into born, while the old telecommunications billing processing from the system to the technology are less able to adapt to situation needs, even to some extent it has limited and hampered business development. So some real-time telecommunications billing systems have come into being. 

　　　The simulation software on real-time billing system for telecommunications pre-processing module to be studied of this subject is a telecommunications-based simulation of real-time billing system software. The fundamental principles and realization processes of the pretreatment of telecommunications billing system can be shown through the simulation; in addtion, it can be regarded as a exploration to new comprehensive real-time telecommunications billing systems; what’s more, we can understand the working process of all real-time telecommunications billing, which has certain practical sense.

　The contents of this research project consist of the following components: 

　(1)The system downloads new zhongxin original phone bill from the switchboard at regular time and put it into corresponding directory.

　(2) Do grundkenntnisse uber conversion for the original phone bill.

　(3) Do standard format for the phone bill which has been switched the code system.

　(4) Regular the number of phone bill which has been standardized.

　(5) check out the phone bill which has been number regulared . 

　(6) Put the correct phone bill into a correct phone bill document, the default phone bill into a default phone bill document, and generate log files.
