Wireless AP Channel Allocation by Interference Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale wireless local area networks, managing channel allocation for a large number of access points is computationally intensive and inefficient, particularly when the number of access points needs to be adjusted, leading to excessive interference and disruption.
Innovation Solution
A channel allocation method that assesses interference degrees of access points and performs partial channel allocation, retaining channels for access points with low interference and reallocating channels for those with high interference, using dynamic channel allocation technologies like Cisco or Aruba, while considering channel inheritance to minimize channel switching.

Engineering Contradiction Analysis
1Reliability
If channel allocation is performed for all access points when the quantity of access points changes, then the channel allocation can be optimized, but the computational burden increases significantly
Solution Approach 1:
The patent segments the access point set into a first access point set (whose channels are retained) and a second access point set (whose channels are reallocated). This segmentation allows the system to perform channel allocation optimization selectively rather than for all access points, thereby reducing computational burden while maintaining allocation optimization where needed.
Solution Approach 2:
The patent applies partial channel allocation by performing channel reallocation only for the second access point set (those whose interference degree reaches the target degree) rather than for all access points. This partial action reduces the computational burden significantly while still achieving the necessary optimization for the most critical access points.
2Object-affected harmful factors
If channels are reallocated for all access points, then interference can be reduced, but the number of channel switches increases
Solution Approach 1:
The patent segments access points into two groups: the first access point set whose channels are retained (avoiding unnecessary switches) and the second access point set whose channels are reallocated (to reduce interference). This segmentation ensures that channel switches occur only when necessary, reducing the overall number of switches while still addressing interference problems.
Solution Approach 2:
The patent applies different channel allocation strategies to different parts of the access point population. Access points with lower interference degrees retain their current channels, while only those whose interference degrees reach the target degree undergo reallocation. This local differentiation reduces unnecessary channel switches while effectively addressing interference in problematic areas.
3Device complexity
If partial channel allocation is performed, then the computational burden is reduced, but the channel allocation optimization may be insufficient
Solution Approach 1:
The patent uses interference degree as a feedback metric to determine which access points require channel reallocation. By continuously monitoring interference degrees and comparing them against a target degree threshold, the system can dynamically identify which access points need optimization, ensuring that partial channel allocation still achieves sufficient overall optimization while reducing computational burden.
Solution Approach 2:
The patent changes the parameter of channel allocation scope from 'all access points' to 'access points whose interference degree reaches target degree'. This parameter change allows the system to adjust the level of optimization based on actual interference conditions, achieving sufficient optimization where needed while reducing unnecessary computations for access points that are already performing well.

AI summary
A channel allocation method and a related apparatus are disclosed. The method is for reducing a quantity of access points with to-be-switched channels 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 with an interference degree lower than a target degree in the plurality of access points, and the second access point set includes an access point with an interference degree reaching the target degree in the plurality of access points.
