Primary Access Node Control for Secondary Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks do not efficiently optimize the number of secondary access nodes serving user equipment based on error rates and backhaul throughput, leading to suboptimal data exchange performance.
Innovation Solution
A primary access node determines a target number of secondary access nodes based on error rates and backhaul throughput, selects a qualifying set with adequate received signal strength, and forms a serving set to optimize data exchange with user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of secondary access nodes is increased to improve data exchange performance, then reliability is improved, but device complexity and backhaul resource consumption increase
Solution Approach 1:
The patent implements dynamic adjustment of the number of secondary access nodes based on real-time error rates and backhaul throughput measurements. The primary access node continuously monitors these parameters and adjusts the serving set size accordingly, transitioning from a static to a dynamic configuration that adapts to changing network conditions.
Solution Approach 2:
The system establishes a feedback loop where the primary access node measures error rates and backhaul throughput, uses these measurements to determine the optimal number of secondary access nodes, and adjusts the serving set accordingly. This closed-loop control enables the system to self-optimize based on actual performance metrics.
2Reliability
If more secondary access nodes are used to improve data exchange reliability, then error correction capability is improved, but backhaul throughput efficiency deteriorates
Solution Approach 1:
The patent changes the operating parameters of the system by adjusting the number of secondary access nodes in the serving set based on measured error rates and backhaul throughput. This parameter adjustment optimizes the balance between error correction capability and backhaul efficiency by selecting the appropriate number of nodes for current network conditions.
Solution Approach 2:
The system dynamically adjusts the configuration of secondary access nodes based on real-time network conditions. When error rates are high, more nodes are activated to improve reliability; when backhaul throughput is constrained, fewer nodes are used to preserve efficiency. This dynamic behavior resolves the contradiction between the two opposing requirements.
3Productivity
If the number of secondary access nodes is optimized based on error rates and backhaul throughput, then productivity is improved, but device complexity and control complexity increase
Solution Approach 1:
The primary access node autonomously performs measurements of error rates and backhaul throughput, calculates the optimal number of secondary access nodes, and adjusts the serving set without external intervention. This self-service capability simplifies overall system control while achieving optimized productivity through local decision-making.
Solution Approach 2:
The system uses feedback from performance measurements to automatically adjust the number of secondary access nodes. The primary access node monitors error rates and backhaul throughput, processes this information to determine the optimal configuration, and implements adjustments accordingly, creating a self-regulating system that improves productivity without requiring complex external control.

AI summary
In a wireless communication network, a primary access node controls the amount of secondary access nodes that serve User Equipment (UE). The primary access node exchanges data with the UE, corrects errors, and determines an error rate. The primary access node exchanges the data over backhaul links and determines backhaul throughput. The primary access node determines a target number of the secondary access nodes based on the error rate and the backhaul throughput. The primary access node identifies a qualifying set of the secondary access nodes that have adequate received signal strength. The primary access node selects a serving set having the target number of secondary access nodes from the qualifying set. The primary access node indicates the UE to the serving set and indicates the serving set to the UE. The serving set of the secondary access nodes exchange data with the UE.
