摘要

電信自由化帶動我國電信產業的蓬勃發展，促使我國近年來的電信服務業者大幅成長，各業者推出的優惠方案及業者與業者之間的拆帳等等各式的計價方式，使得出帳流程日益複雜。而且為了系統效能及計算方式的改進，常常需要進行出帳流程的變動，如何快速因應這些變動則成了重要的課題。
近年來服務導向架構(Service-Oriented Architecture，簡稱SOA)，以其跨網路、跨平台、跨語言的優點，漸漸地成為未來軟體開發的新趨勢。除了上述的優點之外，服務導向架構還具備軟體重用性及可變性，可快速因應日後需求的變動。本論文使用服務導向架構設計與建置ㄧ電信業的出帳系統。利用服務導向架構可快速因應變動的優點來達到出帳流程的需求。
出帳流程需要經過許多作業，包含資料集結、資料載入、計算、輸出等等的步驟，而這些作業複雜且數量眾多，不易重新開發，使用既有的作業必然可減少許多的工作，因此本系統採用整合既有系統上的作業的設計。在本系統中依照系統的需求將整個系統分為「整合既有系統」、「服務整合」、「出帳流程」、「系統監控」及「整合管理介面」這五大功能，並從需求分析、系統設計到實作，終以探討系統所帶來的效益做為總結。

Telecommunication liberalization has prompted a sharp growth in the telecommunication industry and has led to a vigorous growth in the number of service providers in recent years.

The billing process is becoming more and more complex as a result of promotional activities such as special discount offers and the sharing of costs and revenues between service providers.

To improve system performance and pricing formulas, the telecom service providers need to modify billing processes frequently. The issue of making these modifications quickly and efficiently has become an important issue within the industry.

Service-Oriented Architecture (SOA) has become a mainstream software development paradigm in recent years, largely because it can be used across different platforms, is language independent, and has good network interoperability. Additionally, software products developed with SOA are easy to reuse and change.

This thesis introduces the design and implementation of a service-oriented telecom billing system. A typical billing process is composed of several operations, including the aggregation, import, calculation and output of data. It is both difficult and time-consuming to make changes to these processes unless developers can reuse legacy components. This project makes use of legacy components for precisely this reason.

The system required five components: A Legacy Integration Module, A Service Integration Module, A Billing Process, A System Monitor, and an the Integrated Administration User Interface.
