The Research Of Timer-Charging System For Telegraph Station SPC Exchange

Timer-Charging system for telegraph station SPC exchange is the core part of carrier bill processing and settlement, and its accuracy is relevant to vital interests of the majority of mobile phone users and fixed phone users. At present, because of the monopoly of the telecommunications industry, competitive pressures from the market is relatively small, then the equipment and software updates slowly, at the same time, the lack of third-party testing organization to supervise them effectively results in existence of the phenomenon of billing errors to central office PBX time billing system. How to effectively guarantee the accuracy of their billings has become a technical supervision departments, industry, authorities, telecommunications carriers and the general consumer hot issues of common concern.This paper describes the Timer-Charging system for telegraph station SPC exchange works principle and detection methods, then analyses the billing errors carried out by the system in detailed, and puts forward the objective evaluation of the billing system measurement performance specifications and test methods.This paper made an in-depth study on the working principle and billing methods of the Timer-Charging system for telegraph station SPC exchange. With using the latest testing equipment, modern detection technology, communications technology, it made more scientific, effective and conducive detection methods to implementation, and the uncertainty of measurement results were analyzed. The detection methods studied in this paper can be used not only as reference with the implementation of Timer-Charging system for telegraph station SPC exchange measurement test timing in technical supervision department, but also as the self-examination by the telecommunications operators.
