The present invention provides a wireless access point control method, a related device, and a system. An activation signal sent by user equipment is received on a radio resource corresponding to a receiving pattern of a first wireless access point, so that the first wireless access point controls itself to leave a power-saving state according to the activation signal. Therefore, the user equipment may directly send the activation signal to the first wireless access point to switch a working state of the first wireless access point from the power-saving state to a normal communication state as soon as possible. In this manner, a power-saving objective of the wireless access point is achieved, and switching of the wireless access point from the power-saving state to the normal communication state as soon as possible can also be accelerated on a basis of achieving power saving of the wireless access point.
