Design And Implementation Of Roaming Data Exchange System

With all major telecom provider for the whole business operation of the rights and the further industry, especially of 3g licences after the telecom industry in moving aspects of the competition is fierce. more and more. Mobile network move to strengthen the operational capacity, data interchange systems in the implementation of the provinces in the company about data exchange and clearing, roaming user identity and prevent malicious arrear and place for malicious used through illegal means the central role.This article mainly discusses the roaming data exchange system design and implementation. the roaming data exchange system include five parts:roam-in data processing, the local file encoding and upload, process the roam-out data download by group company, decodeing the file download by group company, and data insert into database. The system design calls for high reliability, high testability and high security. The system is concerned about the roam data processing, encoding and decoding. Therefore, Therefore, to the roaming data processing system and the figure for core modules, by roaming data processing, ASN.1 encoding and decoding ASN.1 component of three parts.This article discussed the roaming data exchange systems about data processing, ASN.1 encoding, ASN.l decoding the three main module, Include a summary of the design and detailed design, implement, and testing point and testing methods, etc. Purpose consists in contentment system, you can test the reliability and security required.High reliability:When the local hardware failure, the software in any kind of reliability design technology, the entire system properly;When false operation or illegal operation, the software in any kind of reliability design technology, the system paralysis;For the procedures and data, the use of technology and improve software reliability design on its degree.Testability:System that tests for testing, the system, subsystem tests for testing, can setting the point to test.High security:To prevent piracy and to prevent illegal the user to enter the system uses encryption;To important data and information of encryption;May cause accidental physical harm, significant economic loss of equipment and conditions should be adopted by the security design.This discussion about data interchange systems already in GuangXi telecom the actual application, after 10 months of operation, the system to meet a china telecom company mobile network move about the operation, for security moved the mobile network making contributions.
