INTRODUCTION
For many years, mobile network technology - the Global System for Mobile communication (GSM) and Code Division Multiple Access (CDMA) - has been the dominant means of making voice calls when away from home or the office. Today, mobile packet data networks are just starting to be deployed and have yet to be widely adopted. However, there are ambitious hopes for this technology.
World standards bodies, such as the Third Generation Partnership Project (3GPP), have defined the General Packet Radio Service (GPRS) architecture for second generation GSM, and the packet domain architecture for the Third Generation Universal Mobile Telecommunications System (3G UMTS).1 Unlike telephony, which has been enhanced by numerous revenue-generating supplementary services, such as call transfer, voice mail and the Short Message Service (SMS), packet data transmission provides few supplementary services, making it necessary for operators to earn revenue primarily from basic data transport. Although the standard has defined mechanisms for providing supplementary packet services based on intelligent network architecture and the Customized Applications for Mobile network Enhanced Logic (CAMEL) protocol, their functionality remains limited, particularly when it comes to differentiated charging systems.
