Design And Implementation Of NGMC-Based Online Dealing Platform

The competition of the telecom value-added market is very intense. On one side, content providers are seeking multifunctional, easy customizing system to promote their products. On the other side, consumers are looking for the platform which supports multiple client devices, flexible to operate to choose products and services better. The online dealing platform has been raised under such a premise. The platform can be formed as a B2C business model, it provide dealing services for both PC and mobile users. Logically, it is one part of the NGMC(Next Generation Message Center), which is a marketing name of a product developed by the company which the author works for. NGMC has some independent subsystems, including the dealing platform. The dealing platform includes portal systems(content displaying),dealing system(performing dealing actions) and some business systems for specific business.One key element of this paper is the design of the dealing system. The paper starts form the requirements, discusses why adopting the workflow technology when designing the system. The workflow based dealing engine is also discussed in details, which involves every action point in the dealing flow such as pricing, ordering, confirming, paying, and shipping. It also gives a design of a process instance pool for performance concerns.193 card is a special merchandise of the platform, the card-business system that enables dealing of the card is another key element of the paper. Not like the dealing system itself, which generality and flexibility is the main concern when designing, this system deals with some specific problem, the communication between two systems. The protocol they used is called TELLIN MML, which is not a text-based protocol. This paper discusses the protocol in details, including the MML language, which can be understood by partners' card system . After that, it gives the design and implementation of the system, which has two parts: protocol transforming and communication enabling. Protocol transforming deals with how to transform the message from the dealing system generated command to MML command. And the communication enabling part is simply the java implementation of the TELLIN MML protocol, which enables the communication between the two systems.At last ,this paper discusses some problems the system has by now and the reasons cause them. It also point out the actions can be taken next step.
