Development And Application Of Automatic Stopping And Resetting Service System Of PSTN In CTT Jilin Branch

The competition layout of Teleservice has gradually formed in China.In order to receive the international competition of Telecom OperationIndustry, the business strategy of CTT is gradually changing from serviceorientedto customeroriented.At present, many operators are still adopting the traditional inefficientmanual method, which couldn't accomplish realtimeresetting and will induce more friction between customers and operators especially when thecustomers have paid the default fee.The aim of Automatic Stopping and Resetting Service System is toremedy the condition of manual stopping and resetting service and its lowefficiency , to radically change the handle bottleneck of Billing & AccountSystem and Switching System, to liberate human resource, to raiseefficiency and to resolve unnecessary friction between customers andoperators. From the far sight, the telecom operators can economize theoperating cost and enhance its market competitive power with the help ofAutomatic Stopping and Resetting Service System.Via a lot of investigation , the thesis sums up all kinds of demands ofautomatic stopping and resetting, including realtimestopping and resetting ,nostoppingcustomers handling, centralized management of manualstopping and resetting, jurisdiction management, inquiry and statistics ,operating surveillance and remote maintenance. In addition, the systemmust be compatible to a variety of mainstream equipment interface , andhave faster action speed.The thesis provides a design solution of architecture, data process,business accept and network design. The Automatic Stopping andResetting Service System gets worksheet datum from business and accountsystem via DCN. The stopping and resetting server produce stopping andresetting command via stopping and resetting worksheet. The commandexecution engine sends the formative stopping and resetting command tothe execution software of stopping and resetting command. The executionsoftware seeks the relevant switcher via TCP/IP, and then transmits thecommand to switcher.The thesis describes the software functions of automatic stopping andresetting from the sight of service demands, including downloading the worksheet, loading and executing the stopping and resetting command,configuring the command process, statistics and inquiries , systemmanagement, fault tolerance and interfaces to many outer systems.At last the thesis describes the system's achievement by evaluatingthe hardware platform and revealing the software interface.In the thesis, according to the actual situation of CTT Jilin Branch theauthor optimize d the design of the Automatic Stopping and ResettingService System. Comparing to the other similar software, the system hasfollowing improvements:1. Rational use of the existing equipmentWhile building the system, we do our best to reuse the existinghardware equipments and network resources. Network connection reusedthe existing DCN and switching network. At the same time in order toreduce the number of interfaces to the Billing & Account System, thesystem gets the worksheet datum via existing IP billing server and Billing& Accounting System.2. Supporting the no-stopping customersAmong the telecom customers, there are many key-customers or special customers whose service should never be stopped. The systemprovides two methods to set up the nostoppingcustomers. For existing noremindingcustomers the system will never stop their services. The systempreserves the window to add new nostoppingcustomers.3. Expanding the control right towards establishment unitFollowing the customers'increase and the requirements'change, it isprobably that the control right should be given to the establishment unit.While designing the system we fully consider the users'requirement sothat the system's control manner can be expanded smoothly from provinceunitcenteredto establishment unitcentered.At present the Automatic Stopping and Resetting Service System ismainly aimed at the fixedlinetelecom operators, such as China Telecom,China Netcom, and CTT etc. The system can achieve the batch stopping offixedlineservices, automatic resetting and active stopping and resetting. Itcould be considered to improve the system to make it be applied to morefields including Broadband Services, Intelligent Network Service and soon.
