Research And Implication Of Wireless Aplication Based On GPRS And Middleware

Nowadays, Connection to Internet by wireless was go-go discussion subject. By applying various wireless terminal equipment and combining advanced wireless communication technology and popular middleware technology, structuring practical application system was the important aspect of developing software.In the paper, we analyzed the work and manager condition of traffic police and combined PWAS' practice, discussed the mean of item and structure policy.The paper briefed the GPRS network technology of the system. By compared to SMS, HSCSD, indicated the superiority of GPRS. By structure policy, The paper discussed middleware technology on the middleware class, compare, choice and the definition of WebSphere. On the base of discuss, author further indicated detailed the general design, system organization and software, hardware configuration, security and the configuration between database service and web service of PWAS.On the aspect of the security of PWAS, besides to the firewall and data encryption, we applied to VPN. The paper discussed respectively the protocol, identity authentication, encryption technology, data packet construct and the distinction with person network and so on.The paper mainly introduced function, design and implication of the Sub system of information center of PWAS, discussed farther the search of business, the save of violation, the distribution of data, summarized and analyzed the question of design and development, introduced resolution measures.Finally, we summarized of our design and indicated again the advance technology of PWAS system, discussed the enlargement of system after improving the network technology, at last, as the question of work, we provided the further research.
