Problems solved by technology
SDN technology has been fully developed in the wired network, and some mature technologies can be directly transferred to the wireless communication field. However, due to the huge difference between the wireless channel and the wired channel, the impact of the wireless channel on the SDN controller and the architecture performance has to be considered. Influence, that is, the detection and estimation of inaccurate network status information received by SDN
How to obtain relatively accurate information through SDN, how to achieve the goal of optimizing the wireless communication network system, there is no effective solution so far

The invention provides a wireless communication network performance optimization method based on SDN and an SDN controller. The method comprises the step that inaccurate network state information in a certain area is obtained by the SDN controller, and the obtained network state information is fed back to a receiving unit of the SDN controller by a mobile terminal or a base station through a wireless channel; the SDN controller detects and estimates the obtained inaccurate network state information, operates a system performance optimization algorithm to select an optimal system parameter; and setting information is sent to all base stations or mobile terminals of the system by the optimal system parameter determined by the SDN controller to set parameters. By adopting the method provided by the invention, the quality of service of wireless communication can be improved, a higher signal coverage is provided, the user satisfaction and the overall performance of the system are improved, and thus the purpose of analyzing and optimizing an infrastructure layer is realized.
