Abstract:LWA(LTE WLAN Aggregation) is a promising technology to diversify the traffic of WLAN for reducing the burden of LTE networks and improving the overall system capacity. After introducing the LWA, and the LWA convergence scenario and the integration architecture, this paper describes the existing offloading architecture, and the technical problems and key technologies of LWA system. In addition, the most important access point control technology and resource allocation technology are analyzed. Finally, further research on the LWA system is given in the paper.
Keywords:Long Term Evolution(LTE)  Wireless Local Area Networks(WLAN)  LTE WLAN Aggregation(LWA)  network aggregation  traffic offload
