Guangdong Unicom Comprehensive Clearing System Design

The telecommunication market becomes more and more mature; the competition between market players is going to very extreme heat. In this extreme high-pressure market environment, the telecommunication operators cannot just increase their quality and diversification of telecommunication and network services, but also need to continually consummate their Operational Support System. As an essential part of the Operational Support System– Settlement System is carrying a very important functionality.This treatise studies the Guangdong Unicom comprehensive settlement system design. According to the telecommunications system to support the design specifications, detailing the functional requirements and performance needs of comprehensive settlement system, discussed the Design and Implementation of the Comprehensive Settlement System, focusing on the key technology to carry out the comprehensive settlement system.This treatise includes the following elements: Firstly, the detailed analysis of six functions of functional requirements of the comprehensive settlement system including collection, pre-treatment, wholesale price, settlement, vet check, reconciliations. Then introduced the structure system of the comprehensive settlement system. According to the modular characteristics of Comprehensive Settlement System, herein introduces the module division of the system in detail. Lastly, the paper gives an exposition for key technology used in the comprehensive settlement system, particularly the application of Petri mathematical model used in this system.While the comprehensive settlement system is on line, it will be able to improve in supporting the operators in network settlement, Unicom internal network settlement, roaming settlement, etc.. Simplify the work process and improve work efficiency.
