摘  要
 在電信市場(chǎng)競(jìng)爭(zhēng)的環(huán)境下，計(jì)費(fèi)系統(tǒng)是電信運(yùn)營(yíng)商進(jìn)行市場(chǎng)競(jìng)爭(zhēng)的最重要的核心支撐系統(tǒng)，是電信公司進(jìn)行市場(chǎng)運(yùn)作的神經(jīng)中樞。電信公司都把計(jì)費(fèi)系統(tǒng)的建設(shè)和有效運(yùn)行作為提高服務(wù)質(zhì)量、增強(qiáng)自身競(jìng)爭(zhēng)實(shí)力、刺激業(yè)務(wù)量上升的重要手段。電信為了滿足各種客戶(hù)的需求，提供了很多種的計(jì)費(fèi)方式。但是在新需求的開(kāi)發(fā)過(guò)程中經(jīng)常存在著開(kāi)發(fā)量大、開(kāi)發(fā)周期長(zhǎng)、大量重復(fù)開(kāi)發(fā)等突出問(wèn)題，嚴(yán)重影響著開(kāi)發(fā)的效率和質(zhì)量。通過(guò)組件復(fù)用技術(shù)可以很好的解決上述問(wèn)題。本文從電信計(jì)費(fèi)的業(yè)務(wù)需求方面，設(shè)計(jì)了兩個(gè)基礎(chǔ)組件：
 1.配置文件組件
 讀取和修改xml以及ini格式配置文件中的配置項(xiàng)的值，同時(shí)支持多個(gè)配置文件，并定時(shí)掃描文件是否更新并及時(shí)加載更新。
 2.文件化清單組件
 以文件的方法來(lái)處理清單，采用數(shù)據(jù)文件來(lái)保存清單，采用索引文件來(lái)定位數(shù)據(jù)文件從而找到相應(yīng)的清單，并提供插入，查詢(xún)，更新，刪除等基本接口。
 經(jīng)過(guò)努力，組件已通過(guò)需求、設(shè)計(jì)、開(kāi)發(fā)、測(cè)試等軟件工程的各個(gè)階段，現(xiàn)在已成功發(fā)布。

ABSTRACT
 Because of the competition environment in the telecommunications, the billing system of telecom becomes the most important support systems in the market competition. Telecom regards the billing system as an important way to improve service quality and strengthen its competitiveness. In order to meet the various customer needs, the telecom has provided a lot of billing way. But in the new requirements develop process is often associated with lots of outstanding problems, such as a long development cycle and a large number of repeated codes, which seriously impact on the development of efficiency and quality. It can resolve the above mentioned problems by use the technology of component. Based on the needs of the telecom billing business, this article designs two basic components:
1. Config Component
 Read and modify value of the configuration items in which the file type is xml and ini. As a plus, it can also updates configure items in time when file updated.
2.Documented billing component
 Use a list of files to deal with billing and provide insert, query, update, delete and other basic interface.
 Through the efforts, the system has passed each stage of software engineering such as requirement, design, coding, and test. Now this system already has been released successfully and running well.
 
 
 Key Words：Online charging system,  Components,  Xml and ini Config file,  Documented billing component
