Analysis And Design Of Same SIM Multiple Number Charging System

The elimination of monopolization in telecommunication makes the operators in China compete heavily, while the focus of competition turns from price and resource to management and service. So all operators start pay more attention to operation- system to an advanced position in telecommunication markets.At the same time, vast changes are happening in the international telecommunications market that the percentage of revenue from value-added service in the total revenue is increasing rapidly, especially in China."Same SIM Multiple Number" (SSMN) is a technology used in the telecommunication network, it can provide multiple virtual telephone numbers for one actual number. The service subscribers can use these virtual numbers to communication with others.The charging system is one important component of operation-support system. This paper will introduce the design and implement of the charging system.At the beginning of this paper, the author introduces the background of the system.Next, this paper introduces the SSMN system and the conception of charging, analyses the requirements in detail, designs the function. This paper also gives the design of the charging system, including internal structure, billing of processes, reliability and operation and maintenance management.At last, the author gives a comprehensive summary of implement, and looks forward the charging system.
