Wireless Traffic Channel Release via Signal Quality Delta
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, network resources are inefficiently utilized due to assigned air interface traffic channels not being fully utilized by wireless communication devices (WCDs), leading to network overload despite many channels being inactive.
Innovation Solution
A method to selectively release network resources by determining signal quality deltas for each WCD's traffic channels and releasing those with minimal contribution to aggregate signal quality, making resources available for other WCDs, thereby optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air interface traffic channels are exclusively assigned to WCDs, then each WCD has dedicated communication channels, but network resources are wasted when WCDs do not fully utilize their assigned channels
Solution Approach 1:
The patent implements dynamic channel allocation where the number of traffic channels assigned to each WCD is not fixed but adjusts based on real-time signal quality measurements. The system continuously monitors signal quality deltas and modifies channel assignments accordingly, transforming the static exclusive allocation into a dynamic resource management approach that responds to changing network conditions and WCD performance requirements.
Solution Approach 2:
The system changes the parameter of channel assignment by introducing signal quality delta thresholds. When the delta between individual channel signal quality and aggregate signal quality exceeds a threshold, the system modifies the number of channels assigned to the WCD. This parameter-based control mechanism allows the network to optimize resource allocation based on measurable performance metrics rather than fixed assignments.
2Reliability
If multiple traffic channels are assigned to each WCD, then communication quality is improved, but network overload occurs when many channels remain inactive
Solution Approach 1:
The patent implements a feedback mechanism where the network continuously monitors signal quality metrics for each assigned channel and compares individual channel performance against aggregate performance. Based on this feedback loop, the system identifies channels with minimal contribution to overall signal quality and releases them for reallocation. This closed-loop control ensures that channel assignments are continuously optimized to match actual communication needs, preventing both over-provisioning and under-provisioning of resources.
Solution Approach 2:
The system discards (releases) traffic channels that are assigned to WCDs but contribute minimally to aggregate signal quality. These released channels are then recovered and made available for assignment to other WCDs that may benefit from additional capacity. This discarding and recovering process transforms idle or underutilized resources into productive assets, improving overall network resource utilization while maintaining adequate signal quality for active users.
3Reliability
If network resources are devoted to maintaining assigned channels, then channel availability is ensured, but resources are wasted on channels not actively used for communication
Solution Approach 1:
The patent applies preliminary action by proactively releasing channels that are likely to be underutilized before network resources become critically depleted. The system monitors signal quality deltas and releases channels when thresholds are exceeded, preventing the accumulation of unused channel assignments. This proactive resource management ensures that network resources remain available for WCDs that actually need them, rather than being tied up in maintaining excessive channel assignments across the network.
