Design And Implementation Of PHS Service System For Customers

PHS's formal title is "Wireless Phone", which is a wireless access in application the market of the operators operate wireless telephone business collectively. It uses micro-cellular technology, client access to wireless local call and provides the use of free movement of the telephone service in the coverage region. PHS can provide a high quality voice service, high-speed wireless data access and colorful messages, E-mail and browse the contents of such value-added service. It is the supplement and extension of fixed telephone. It uses the fixed telephone network, accesses to the network wirelessly and provides a certain range of wireless mobile communication system.PHS business management system as a launch PHS business "the main item" system, includes the production processes, files and number of users and resources with UT Starcom platform for the exchange of communications management, etc. PHS customer service management system is based on mature of TCP/IP, object-oriented software engineering methods, adopts the client-server software solution. Our work uses PowerBuilder development language and Oracle database, designs and implements a completely paperless, highly secure, practical, reliable and efficient integrated system PHS customer service in the Windows operating system platform.Oracle Distributed Database is a large relational database, with openness, portability, distribution and data integration. The relations database has the succinct bright construction of data, used the non- process user language, the data in dependence is high, the data used " Relates " Namely the two-dimensional table organization way, a table may deposit data itself, also may store between the data the relations. A database can be composed of a number of tables, user of the database is to operate on the operating table.Oracle database is applicable to the needs of highly distributed data processing, data confidentiality and security departments, because it can ensure data consistency and integrity.PowerBuilder is the only cross-platform support to the client application development tools. In addition to Windows, it also supports Macintosh and Unix Platforms. PowerBuilder can support all the operating platforms with the implementation of a code of documents P-code. PowerBuilder can provide excellent returns generation, complete online help and rich Internet visit functional characteristics and components.Our work is the Shenyang Communications PHS business computer integrated management system of customer service system, including PHS business services process admissibility function, PHS investigation, PHS fault declaration function, PHS calls inquiries, payment inquiries, charges, inquiries, inquiries by fax functions, PHS payment functions and voice other related functional expansion. The second section focuses on the PHS customer service systems of the physical structure, operation and management of functional design and analysis.In the third chapter, we introduce the whole system and data structure, including small quick single plane table, public opinion detailed list table, long-distance telephone detailed list table, information detailed list table, short note detailed list table, CMODE detailed list table and IDA detailed list table. Each item tabulates separately lists the field name, the field type and the simple explanation, we may act according to the concrete data category to carry on between the database and the exchange.System security is the prevention of accidents and complex system development, research the security theory, methods system. In the fourth chapter we point out clearly that the so-called security system is in the system during the life of the application of system safety engineering and management methods, which can identify the risk sources, and take measures for their control of thesmallest risk, thus allowing the system to the required performance, time and cost within the reach of the best safety.In this paper, the management system uses the large Oracle relational database to ensure system security. It has the following advantages:(1) Truly realized the multithreading, the multi- advancements C/S data processing, this enables the database handling core by the least systems expenses, completes the high strength data processing request by the maximum efficiency.(2) Has strong network and distributed data processing capability, and can support TCP/IP, SPX/IPX, SNA and other 25 different network protocols.(3) Powerful data integrity control. Service Integrity provides control and consistency control, without having to worry about the loss of the relationships between parents and child.(4) Multiple data security. It builds multi-data images in multi-services and maintains their consistency by the database core.(5) System may carry on the different level according to the operator jurisdiction to the database level data locking, to database management and logarithm according to authorized work unification by database administrator true-time operation.In Chapter 5 we introduce the relationship between the PHS customer service subsystem and "1997 Project". To share the "97" data resources, our system includes customer information, order processing, process, order processing, telecommunications business telephone admissibility single, billing information, etc.Finally, we expatiates the PHS system's overall summary of the advantages and disadvantages, summing up the past and current customer service system, and point out future work should focus on how to improve PHS the coverage issue...
