Abstract: Embodiments of the present invention provide an air-ground communication control method. The method is applied to a hierarchical network that includes a ground network and at least one aerial network, and the method includes: receiving, by a ground platform, location information of a high-altitude platform sent by the high-altitude platform, where the ground platform is located in the ground network, the high-altitude platform is located in the aerial network, and a beam of the high-altitude platform covers the ground platform; determining a beam direction according to location information of the ground platform and the location information of the high-altitude platform; and sending beam width information to the high-altitude platform in the beam direction, where the beam width information is used to adjust an interval of sending the location information of the high-altitude platform.

Abstract: This application provides a collaborative node-based positioning method, a to-be-positioned node, and a collaborative node. The method includes: obtaining a collaborative positioning node list corresponding to each collaborative node that can directly communicate with the to-be-positioned node; selecting, according to the collaborative positioning node list corresponding to each collaborative node, a collaborative node corresponding to a collaborative positioning node list in which a quantity of collaborative nodes being the same as that in a target list corresponding to the to-be-positioned node is largest; and performing positioning on the to-be-positioned node by using an anchor node and each monitoring node, where the anchor node is the selected collaborative node, and each monitoring node is each of same collaborative nodes between the collaborative positioning node list corresponding to the anchor node and the target list.
