Access Node Channel Loading Management via Device Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of wireless devices communicating with an access node increases, managing communication link resources becomes challenging due to high demand for communication services, leading to channel loading thresholds being exceeded, which can result in inefficient resource allocation and service degradation.
Innovation Solution
The system identifies active wireless devices with applications meeting specific criteria, ranks them based on modulation and coding schemes and pending data, and instructs them to switch to a secondary access node channel until the primary channel's loading threshold is met, ensuring optimal resource utilization.

Engineering Contradiction Analysis
1Productivity
If the number of wireless devices communicating with an access node increases, then communication service demand increases, but channel loading exceeds threshold leading to resource allocation inefficiency and service degradation
Solution Approach 1:
The patent segments the channel resources by dividing wireless devices into different groups based on their modulation and coding schemes (MCS). Devices are separated into first group (higher MCS indices) and second group (lower MCS indices), allowing independent management of each segment. This segmentation enables the system to handle increased device count by managing different device types through separate channels or resource allocations, preventing any single channel from becoming overloaded.
Solution Approach 2:
The patent applies local quality by assigning different channel resources to different device groups based on their specific requirements. Higher MCS devices receive allocation on first channels while lower MCS devices use second channels, creating locally optimized resource distribution. This ensures that each device group receives appropriate service quality matched to its capabilities, improving overall system reliability under increased loading conditions.
2Reliability
If wireless devices are ranked and redirected to secondary channels, then primary channel loading is reduced, but device complexity increases due to ranking and redirection management
Solution Approach 1:
The patent implements self-service by enabling wireless devices to autonomously determine their own ranking and channel allocation based on their MCS and pending data characteristics. Devices self-evaluate their requirements and are automatically placed into appropriate groups without requiring complex centralized management. This self-organizing mechanism reduces device management complexity while maintaining effective channel loading control through distributed decision-making.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting channel allocation decisions based on real-time measurements of device characteristics (MCS indices and pending data amounts). The system changes allocation parameters such as which channel a device uses based on current loading conditions and device properties. This dynamic parameter adjustment allows the system to maintain optimal loading distribution without requiring complex static management rules.
3Productivity
If devices with same MCS are further ranked by pending data amount, then channel allocation optimality improves, but measurement and detection complexity increases
Solution Approach 1:
The patent applies partial action by implementing detailed ranking only for devices within the same MCS group that have similar characteristics. Rather than ranking all devices exhaustively, the system performs selective ranking based on pending data amounts only when necessary (i.e., when devices have identical MCS). This partial application of complex ranking logic maintains allocation optimality for critical cases while avoiding the excessive measurement complexity that would arise from comprehensive ranking of all devices.

AI summary
It is determined that a first channel loading of a first access node channel meets a loading threshold. Wireless devices in active communication over the first access node channel are identified, the wireless devices comprising an application running on each wireless device, each application comprising an application requirement which meets an application requirement criteria. The identified wireless devices are ranked into a first order based on a modulation and coding scheme assigned to each wireless device, and are further ranked in a second order within the first order based on an indication of an amount of data pending transmission from each wireless device when two or more wireless devices are assigned the same modulation and coding scheme. Each identified wireless device is instructed to operate on a second access node channel according to the second order, until the first channel loading does not meet the loading threshold.
