Abstract

The invention relates to a wireless network switching method and system. The method comprises the following steps: according to simulation models, built in advance, of multiple wireless networks, obtaining network flow track graphs of the wireless networks within a period of time, wherein the network flow track graphs represent network congestion states; predicating network flow of the wireless networks at present according to the network flow track graphs, and obtaining long-range dependence historical network flow; obtaining state parameters of one wireless network that is accessed at present in real time, and determining whether a network switching condition is satisfied according to the state parameters; and if the network switching condition is satisfied, determining one optimized network at present according to the long-range dependence historical network flow and the state parameters, and switching the previous network to the optimized network. The above wireless network switching method and system enable the ping-pong effect and unnecessary switching decisions to be reduced, and enable terminals to access the optimized network quickly, accurately and effectively.
