User and network matching method under scene of coexistence of multiple wireless networks

The invention discloses a user and network matching method under the scene of coexistence of multiple wireless networks. A user terminal acquires feature information accessed to the wireless networks, then the optimal matching degree between the user terminal and each wireless network is calculated, and finally the optimal matching degree of all the wireless networks is compared and the wireless network of the highest optimal matching degree is selected for accessing. The obvious characteristics of the user and network matching method are that the three elements of user preferences, business requirements and load balance are considered from the perspective of the user to perform user and network matching selection so as to respect the subjective preferences of the user and maximize the user experience; the network resources can be reasonably utilized, the network load can be effectively balanced and congestion can be avoided; and the data rate actually provided by the network is dynamically adjusted according
