The Design And Application Of The System Of Integrated Services Access Gateway In WAP Business Network

Along with the incredible rise of demands of wireless communication and amount of information, Wireless-Internet that realized the mutual supplement with advantages of two major techniques, Network and Wireless Communication, has been created and applied to the practice. Among the development of the technique of Wireless-Internet, the technique of WAP, which has became the global standard in the field of browsing web pages through the Wireless Network and by the machines of cell phone and other terminal devices, undoubtedly occupies extremely important status.Under the background of this technique's development, the thesis, which consults CDMAlX's WAP business of China Unicom, has put forward a solution which can be used in WAP with the framework of door which is ISAG(Integrated Services Access Gateway), systematic expatiated the structure model and function of Integrated Services Access Gateway and realized WAP business network's ISAG platform. In the proposed solution, which is about ISAG platform, the system can be divided into two modules, one is management and charging and other is SP connection proxy. The formal module in charge of the management of some information, which is about WAP browsing business, such as users, SP and business, etc. Meanwhile, the module can" compute and analyze the results of users' visit and charging as well as provide interfaces between the system and exterior devices, such as Customer's service centre, SMG. The later module which is the channel of control stream and business stream mainly accomplishes the task of building a physical path between the system and SP. In the same time, it can get business' s URL which can be main base of charging according content. The main function of the module in whole WAP browsing business is to collect the fee of URL, authorize of connection SP and users, filtrate website addresses and contexts.On the base of ISAG platform, we develop WAP News platform which canoffer users the business that is about browsing news after connecting the news business to ISAG platform, so as to test the design of Integrated Services Connection Gateway's feasibility and practicability.
