Abstract: A channel allocation method and a related apparatus are disclosed. The method is for reducing a quantity of access points whose channels are to be switched and reducing an amount of calculation for channel switching. The method includes: obtaining interference degrees of a plurality of access points; and performing partial channel allocation based on the interference degrees. The partial channel allocation includes: retaining an operating channel of an access point in a first access point set, and reallocating an operating channel to an access point in a second access point set. The first access point set includes an access point whose interference degree is lower than a target degree in the plurality of access points, and the second access point set includes an access point whose interference degree reaches the target degree in the plurality of access points.

Abstract: An obstacle recognition method and apparatus, and a related device are provided. The method includes: obtaining an actual path loss value between a first AP and a second AP, path loss value pairs between a terminal and a plurality of AP pairs, and path loss values of the plurality of AP pairs; obtaining, based on the path loss value pairs between the terminal and the plurality of AP pairs, an AP pair similar to an AP pair formed by the first AP and the second AP; obtaining a second path loss value between the first AP and the second AP based on a path loss value of the similar AP pair; and comparing the second path loss value between the first AP and the second AP with the actual path loss value, to determine whether an obstacle exists between the first AP and the second AP.
