Research On The CNC's PHS Computer Business And Billing System

In order to seek the new economical growth spot, the Shenyang CNC decided to introduce and develop the PHS (Personal Handy-phone System) service in the first half year of 2003.Therefore, the company requested the computer network department develop "the PHS computer business and billing system of Shenyang CNC".This topic mainly studies the system design and the construction process of "the PHS computer business and billing system of Shenyang CNC ". Based on this study, the Shenyang CNC can improve this system in Shenyang city, thus obtains the advantageous status in telecommunication market competition and provides the experience to other telecommunication business.This system takes the enterprise management as a foundation, packs such subsystems as business system, data acquisition system, billing system, earning inquiry system through the analysis and localization of PHS service, also the enterprise flow reconstruction, subsequently obtains the business, costs and inquiry function of PHS service. It plays the powerful support role in PHS service operation, therefore will be the important part of telecommunication synthesis management system in the future.This system mainly applies the computer and network technology, uses the small machine of ALPHA4000 and ES45, HP TRU64UNIX5.1A operating system and ORACLE 9I large-scale relational database, also takes the network security technology such as TCP/IP agreement as a foundation, so it has the high level of performance, stability and security.While reconstructing the service flow, this system has used the open client/server environment, the graphical user interface (GUI), Centre for Advanced Studies in Environment (CASE) and the object-oriented technology (OOT) to guarantee the system's high usability and extension impossibility. In the design and application course of this system, the future development demand, the user individuality service demand and the fees policy flexibility has been considered. According to its function need, operation platform and development environment, this system has been divided into several subsystems, such as business system, data acquisition system, costs billing system, earning inquiry system and so on. This system can guarantee the relative independence of all the subsystems in the certain connection situation on the basis of present business management pattern, but unifies the standard application data in overall, therefore other application systems can share its data. Its programming has used modular design thought, therefore enabled this system to have a more remarkable flexibility and extension impossibility.In the implementation process of "the PHS computer business and billing system of Shenyang CNC ", the software engineering implementation standard has been utilized to guarantee effectively the implementation and construction of entire project.This system has the advanced design idea, and construct complete independently to save a large cost for Shenyang CNC. Such a large-scale system needs at least six million Yuan of constructions expenses if request other company to design and develop. Moreover, this system's hardware equipment only invested 6.2265 million Yuan, has also saved nearly 700 thousand Yuan for system integrations expense. Take the Dalian CNC as the example, its system was constructed by Beijing Yiyang company, the system capacity is only about Shenyang'2/3, but the hardware equipment invested 4 million Yuan, and the software system construction invested 3.1 million Yuan, simultaneously Dalian CNC pays hundreds of thousands of Yuan for annual maintenance costs.The implementation of "the PHS computer business and billing system of Shenyang CNC " obtained the affirmation and the high praise of Liaoning computer network project and software evaluation center, the Shenyang science and technology appraisal experts as well as the CNC company. In 2003, the CNC of Dalian, Dandong and other cities came to Shenyang to inspect and study this system one after another, all expressed the approval to it.After applied since June 2003, each target of this system has achieved the design request. In the PHS service promotion of company in 2003, the daily user management peak amount was to achieve 9600, fully proved the handling ability and usability of this system. Due to usage of the advanced design idea, within more than one year of on-line operation, this system satisfied the users'individuality service need,the fees policy flexibility, and system' s extension impossibility. This system played a important strut role to the PHS service development , has had a remarkable economic and social efficiency.At present, this system is used throughout the Shenyang local network, and obtains the full affirmation of CNC Group company and Liaoning CNC. CNC Group company wants to promote this system to other provinces and cities. Although this system serves the PHS service presently, it contains business system, billing system, these two system apply in many domains. Thus if "Shenyang communication PHS service computer business and billing system" we developed makes partial revisions, it can apply to many other domains. The application prospect is extremely optimistic.In July 2004, Shenyang Science and Technology bureau managed and convened the Appraisal meeting of "the PHS computer business and billing system of Shenyang CNC"which was developed by Shenyang CNC. Appraisal committee earnestly listened to the development report, fitness report, technical novel report,examination report and user utility report. After the full discussion, committee consistently thought:1. The documents material provided is integral and standard, conforms to the requirement of technical achievement appraisal;2. this system divides into several subsystems, such as business system, data acquisition system, costs billing system, earning inquiry system and so on , according to the PHS service characteristics, and has met the present need of PHS service. Through one year's operation, the system's quality is confirmed stable and reliable, each technical specification has achieved the design goal;3. This system uses the C/S pattern,TRU64UNIX5.1A operating system, ORACLE9 database and VC++ to develop the multi- advancement and multi-thread PHS handling ,uses the integration technology and SAN memory technology to develop the system mass memory and the system on-line hot backup, uses MSIP agreement to develop the docking between the system and UTSTAR COM software platform;4. This system had fully considered the future development demand, the user individuality service demand and the fees policy flexibility in the course of design and implementation, and guarantee the system'extension impossibility.In summary, this system has extremely vital role to the PHS service development, has had the remarkable economic efficiency and social efficiency, each technical application achieves the domestic leading level in the PHS business management aspect.
