AI Technical Summary

Technical Problem

In WLAN networks, there is severe co-channel interference among densely deployed access points (APs). Existing channel allocation schemes based on path loss are affected by factors such as radio frequency signals and buildings, resulting in inaccurate neighbor relationships and failing to effectively reduce interference.

Method used

By combining the physical topology and path loss topology of APs, a more accurate neighbor relationship can be obtained. Channel allocation can be performed using the allocable channel set to ensure that neighboring APs use different channels and reduce co-channel interference.

Benefits of technology

It enables more accurate allocation of suitable channels to APs under limited channel resources, reduces co-channel interference, improves channel allocation efficiency, and reduces collisions.

Abstract

This application discloses a channel allocation method and related apparatus, relating to the field of communication technology. The channel allocation apparatus acquires the physical topology and path loss topology of multiple access points (APs) in a target area. The path loss topology represents the path loss between any two APs in the target area, and the physical topology represents the physical location or distance relationship between any two APs in the target area. The channel allocation apparatus determines a target topology based on the physical topology, path loss topology, and a set of allocable channels. The target topology represents the neighbor relationships between the multiple APs. The channel allocation apparatus allocates channels to the multiple APs based on the set of allocable channels and the target topology. The physical topology more accurately reflects the neighbor relationships between APs, and allocating channels to APs based on the physical topology can reduce co-channel interference between APs.
