費率組合在電信業市場上行之有年，但長久以來，電信業一直以傳統的語音服務計費模式套用在所有的服務上，其中通話費的部分則是以通話時間作為計費的基礎，甚至連架構在語音服務上的數據傳輸也是如此。新引進的整合封包無線電服務(General Packet Radio Service, GPRS)在技術本質上與語音服務有很大的差異，因此計費方式也必須作一番變革，以傳輸量作為計費的基礎是較佳的選擇。 　由於GPRS屬於寬頻數據網路，再加上無線電資源的有限性，在傳輸品質上的要求也較高，GPRS在設計時就已經規劃了支援「服務品質(Quality of Service，QoS)」。因此，品質因素也應被列入計費的要項之一。 　本文嘗試提出一個GPRS的計費架構，並找出所有的計費因子，使未來經營GPRS的電信業者的行銷人員及計費系統設計人員有一個依循的準則。而在實例中也的確發現本文所提出的GPRS計費架構，可以應用在現實的計費系統上，提供各式各樣的費率組合。 / Pricing Package was used in telecommunications industry for many years. However, the operators always use the conventional voice service packages to cover the data services. The charge for every call is duration based but it cannot be applied for new introduced technology, e.g. GPRS. The technology of GPRS is quite different with the voice services; the charging model will be different as well. A volume-based charging model is an ideal way. 　GPRS is a broadband mobile data service. According to the limitation of wireless resources, the demand of quality of service is high. GPRS was designed to support QoS (Quality of Service) which can be considered as a charging factor. 　This material tried to propose a GPRS charging architecture and find out all of the charging factors. The marketing people and charging system designers of GPRS operators can create their own pricing packages based on this GPRS charging architecture. In the case study, we found that this GPRS charging architecture can be applied to the real world charging systems and provide kinds of pricing packages.
