Research And Application Of Fusion Technology On WLAN And 3G

With the rapid development of wireless broadband technology, operators through the WLAN and WCDMA technology provide Internet access services for users. WLAN and WCDMA have different characteristics:WCDMA access mode allows the users to achieve business needs anytime and anywhere, but the bandwidth resources are limited; However WLAN technology can be used as the supplementary of fixed network and WCDMA. And it can make networking more flexible and provide high-bandwidth.The paper proposed to achieve the intergration of WLAN and WCDMA by analyzing the WLAN and WCDMA their technical characteristics, development patterns and current status, proposed to achieve the integration of WLAN and WCDMA. Through reading new technologies of broadband wireless access, the writer deeply analyzed the characteristics of WLAN and WCDMA and then proposed a networking scheme based on WLAN and WCDMA wireless broadband access system. The writer combined with his knowledge, involved in the design of Pingdingshan Unicom WCDMA + WLAN project, and organized the corresponding implementation of the project, ultimately proved the correctness of the design.At the same time the paper also investigated the solutions and key technologies of heterogeneous network convergence, the switching strategy and realization method based Qos.
