Wireless Channel De-allocation Order Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently managing the termination of wireless channels in shared wireless bands, particularly when higher priority entities require the band, as this can disrupt communications for low-priority users and lead to inefficient use of the frequency spectrum.
Innovation Solution
A management resource, utilizing computer processor hardware and software/firmware, controls the orderly and timely termination of wireless channels by prioritizing and scheduling the de-allocation across multiple wireless access points based on data communication loads and channel allocation information, ensuring continuous communications for users.

Engineering Contradiction Analysis
1Productivity
If wireless channels are de-allocated from low-priority users to accommodate higher priority entities, then spectrum usage efficiency is improved, but service continuity for low-priority users deteriorates
Solution Approach 1:
The system performs preliminary actions by proactively identifying channels that will be de-allocated and initiating handoff procedures before the actual de-allocation occurs. This allows low-priority users to be transitioned to alternative channels in advance, maintaining service continuity while enabling the spectrum to be re-allocated to higher priority entities.
Solution Approach 2:
The patent introduces an intermediary mechanism (handoff process) that mediates between the de-allocation requirement and service continuity. The handoff process acts as a bridge, transferring users from de-allocated channels to alternative channels, thereby resolving the conflict between spectrum efficiency and service reliability.
2Speed
If channel de-allocation is performed across multiple wireless access points simultaneously, then spectrum re-allocation speed is improved, but communication disruption worsens
Solution Approach 1:
The system segments the channel de-allocation process across multiple wireless access points, performing handoffs in a coordinated sequence rather than simultaneously. This segmentation allows the overall re-allocation to proceed efficiently while minimizing disruption at any single access point, as users are transferred gradually across the network.
Solution Approach 2:
The patent implements a dynamic handoff approach where the de-allocation process adapts to real-time network conditions and user distributions across access points. This dynamic sequencing optimizes both the speed of re-allocation and the minimization of disruption by adjusting the order and timing of handoffs based on current system state.

AI summary
According to one configuration, an access point control resource receives channel allocation information indicating a change to allocation of channels in a wireless band currently used by multiple wireless access points to communicate with multiple communication devices in a network. The access point control resource uses the channel allocation information to identify a particular wireless channel (such as a de-allocated wireless channel) to be terminated from use by the multiple wireless access points. In accordance with the channel allocation information, when vacating use of the de-allocated channel, the access point control resource controls an order of terminating use of the particular wireless channel by the multiple wireless access points.
