Development Of The Query Software Supporting Download About The Fields Phone Numbers Owing To

With the continuous improvement of performance of mobile phones, mobile value-added services market development trend has been gradually become clear.Mobile value-added services will be a value-added business computer after another important business growth. After fully analyzed the demand and development trend of the mobile phone value-added application's markent and the characters of other cell phone application , with practical develop experience ,the author designed and implemented a SIM card location query system supporting download based on J2ME. The system designed by J2ME because Java have a good transportability and cross-platform-ability,so we can avoid the problem brought by differences in many cell phones or other mobile terminal units. At the same time, it's powerful network communication ability can play an important role in the coming 3G times. Based on the query system, this paper make a correlation theoretical study , and do some experiments and technological development. this paper focus on the host WAP websites, System Architecture design and implement ,etc. the WAP website developed by WML, with the advantage of J2ME integrated with WML. According to the function requirement and the characteristic of MVC mode, the System analyze and design from the implement of MIDP main class,model class, XML parser. At last, the results of actual runs was given by this paper.
