A wireless network handover method, comprising: obtaining, by a handover device, a distance between a terminal and a current access point, to determine a change trend of the distance between the terminal and the current access point; and if the handover device determines, based on a correspondence between the change trend and a neighboring access point of the current access point, a target access point to which the terminal is to be handed over, handing over, by the handover device, the terminal from the current access point to the target access point; after the handover device determines that the terminal accesses the current access point, discontinuously obtaining, by the handover device, a round trip time, RTT, between the terminal and the current access point at a first frequency, and obtaining the distance between the terminal and the current access point based on the RTT; and if the distance between the terminal and the current access point is greater than or equal to a first pre-handover distance threshold, or the distance between the terminal and the current access point is less than or equal to a second pre-handover distance threshold, obtaining, by the handover device, an RTT between the terminal and the current access point at a second frequency, wherein the second frequency is higher than the first frequency, and obtaining the distance between the terminal and the current access point based on the RTT; or if the distance between the terminal and the current access point is greater than or equal to a first handover distance threshold, or the distance between the terminal and the current access point is less than or equal to a second handover distance threshold, stopping, by the handover device, obtaining an RTT between the terminal and the current access point. obtaining, by a handover device, a distance between a terminal and a current access point, to determine a change trend of the distance between the terminal and the current access point; and if the handover device determines, based on a correspondence between the change trend and a neighboring access point of the current access point, a target access point to which the terminal is to be handed over, handing over, by the handover device, the terminal from the current access point to the target access point; after the handover device determines that the terminal accesses the current access point, discontinuously obtaining, by the handover device, a round trip time, RTT, between the terminal and the current access point at a first frequency, and obtaining the distance between the terminal and the current access point based on the RTT; and if the distance between the terminal and the current access point is greater than or equal to a first pre-handover distance threshold, or the distance between the terminal and the current access point is less than or equal to a second pre-handover distance threshold, obtaining, by the handover device, an RTT between the terminal and the current access point at a second frequency, wherein the second frequency is higher than the first frequency, and obtaining the distance between the terminal and the current access point based on the RTT; or if the distance between the terminal and the current access point is greater than or equal to a first handover distance threshold, or the distance between the terminal and the current access point is less than or equal to a second handover distance threshold, stopping, by the handover device, obtaining an RTT between the terminal and the current access point.
