Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks face inefficiencies in managing and allocating wireless bandwidth to customer premises equipment, leading to suboptimal service levels and interference issues due to random allocation methods.
Innovation Solution
A tiered service management resource is introduced to oversee the allocation and re-allocation of wireless bandwidth based on customer premises equipment's service tier and spectrum scan results, ensuring optimal bandwidth distribution and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If random allocation methods are used for wireless bandwidth, then allocation simplicity is maintained, but service level optimization and interference management deteriorate
Solution Approach 1:
The patent segments the wireless bandwidth allocation process into two distinct stages: (1) SAS performs initial channel allocation to base stations, and (2) a tiered service management resource performs secondary re-allocation to customer premises equipment. This segmentation allows each stage to focus on specific optimization goals while maintaining overall system coordination.
Solution Approach 2:
The patent introduces a tiered service management resource as an intermediary between the SAS and customer premises equipment. This intermediary receives the SAS-allocated channels and performs intelligent re-allocation based on service tiers and spectrum scan results, acting as a mediator that optimizes bandwidth distribution without requiring direct SAS-CPE communication.
2Device complexity
If uniform bandwidth allocation is provided to all customers, then allocation complexity is reduced, but service differentiation and user experience deteriorate
Solution Approach 1:
The patent applies local quality by providing different bandwidth allocations to different customer premises equipment based on their service tiers. Higher-tier customers receive priority allocation with more reliable channels, while lower-tier customers receive standard allocation. This allows service differentiation without requiring completely separate allocation systems.
Solution Approach 2:
The patent implements dynamic bandwidth re-allocation where the tiered service management resource continuously monitors spectrum conditions and adjusts channel assignments based on real-time needs. This dynamic approach allows the system to adapt to changing service requirements and interference conditions while maintaining a unified allocation framework.
3Device complexity
If conventional SAS allocation is used without re-allocation, then system simplicity is maintained, but interference management and spectrum efficiency deteriorate
Solution Approach 1:
The patent performs preliminary spectrum scans at customer premises locations before finalizing bandwidth allocation. The tiered service management resource uses these scan results to predict potential interference conditions and pre-adjusts channel assignments to avoid problematic frequencies, improving spectrum efficiency before actual deployment.
Solution Approach 2:
The patent implements a feedback mechanism where spectrum scan results from customer premises equipment are fed back to the tiered service management resource. This feedback loop enables continuous optimization of bandwidth allocation based on actual spectrum conditions, allowing the system to adapt and improve spectrum utilization over time.

AI summary
A tiered service management resource providing management of wireless channels in a network environment receives notification of wireless bandwidth such as multiple wireless channels allocated by a spectrum access system (a.k.a., SAS). The spectrum access system allocates the wireless channels for use by a wireless base station in the network environment. Prior to re-allocating the wireless bandwidth (such as a selected wireless channel) to customer premises equipment, the tiered service management resource further receives a communication indicating a wireless spectrum scan performed at a location from which customer premises equipment in the network environment is (being) installed to wirelessly communicate with the wireless base station. Based on an identified fixed wireless service tier (or level) assigned to the customer premises equipment and supplemental information such as the wireless spectrum scan, the tiered service management resource allocates a selected wireless channel from SAS-assigned bandwidth for use by the customer premises equipment.
