Wireless communication method, terminal, base station and wireless communication system

The invention provides a wireless communication method, and further provides a corresponding terminal, a corresponding base station and a wireless communication system. The wireless communication method comprises the following steps that at least one piece of network-side real-time state information is acquired from a wireless mobile communication network by the terminal, and whether the network-side real-time state information meets preset network-side state conditions or not is judged to acquire a first corresponding judgment result; or a network judgment result generated by the wireless mobile communication network according to the network-side real-time state information is acquired by the terminal; whether scanning operation of a wireless local area network (WLAN) can be executed or is permitted to be executed or not and/or whether a wireless local area network module in the terminal needs opening or not is determined by the terminal according to the network judgment result or the first judgment result. Due to the adoption of the technical scheme, whether scanning of the WLAN can be executed by the terminal or not can be determined according to the actual situations of the terminal side or the actual situations of the network side to reduce terminal power consumption as much as possible.
