Performance Research Of Value Added Service In Mobile Networks

With the fast development of information technology, internet and mobile communication technology have been backbone industries. Their development is inflecting the way people getting the information and the life people live. Value Added Service has developed fast, SMS, MMS, WAP browser are our familiar Value Added Services.Because of the fast development of mobile networks and wide foreground of mobile Value Added Service, the competition among Telecommunications Operators becomes more furiously, Telecoms Operators pay more attention to improving the qualities of services and exploring new services, so the performance testing of Value Added Service in mobile networks is especially important to meet the requirement of users.For improving the testing system in being, the dissertation designed a performance testing system of Value Added Service in mobile networks to test the performance, and from the issue we can discover the problem of mobile networks and how to improve.The article firstly gives some knowledge of mobile networks and Value Added Service, and then indicates the importance of the test of Value Added Service, secondly it describes GPRS networks and WAP protocols and WAP application based on GPRS particularly. Last but not least it gives a detailed presentation of the design and implement of the test system, especially the design and realization of SMS module, and a summary at the end.During the session of system design and implement the main work in this thesis includes: Firstly I have read a lot of WAP Protocols in WAP Forum (http://www.wapforum.com) and OMA (Open Mobile Alliance),...
