Design And Implementation Of Billing Subsystem Of Message Gateway

Under the push of information technique revolution,along with the development of China Mobile's business,as the support system for the telecommunication business,the billing subsystem of message gateway is to also be more and more completed,the business of the system's expand ability itself,the function,stability of the system itself,and its credibility also becomes more and more fall behind the step in ages,even the maintenance expenses of the system year by year increases,therefore,set up a stability of,high performance of,the business expand ability strong of,can support China Mobile's message business's billing subsystem of message gateway is the utmost urgency.In the paper,by comprehensive making use of the software engineering's thoughts and methods,design and realization the correspondence interface of the message gateway and billing center,namely the billing subsystem of message gateway,including the system function module such as common message handling,business processing,system configuration and daily log record etc..the system development platform is based on Linux operating system,adopt MPM and ActiveServer etc.various more popular server progress management framework,to adopting the shared memory technique to store messages,use the queue mechanism etc.,the division of the system function module,have the characteristics of independence,high cohesion and the low coupling,and makes the system logic is quite clear,greatly improves the system portability,the system expansibility,and the system availability.The system greatly shorten the development period by reusing framework,the development and usage of test tools,for example,the emulators,promised development efficiency,lowered development cost.Through the actual apply of the system,proved that this system has clear structure,efficiently,stable and expansive good design,and come to the customer and the need of system,lowered the cost and maintenance expenses of the system,improved universal property of the billing subsystem of message gateway as an supporting system in the telecommunication profession.
