Idle Mode Performance Degradation Reporting in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems face inefficiencies in reporting performance degradation from wireless devices, particularly in idle mode, leading to unnecessary signaling and resource overload when multiple devices report the same issues, which can hinder timely auto-healing and increase latency.
Innovation Solution
A network node and wireless device configuration that enables real-time reporting of performance degradation in idle mode, with restrictions based on rules such as network load, location, and event type, to prevent redundant reporting and optimize resource usage, allowing the network to focus on critical issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If wireless devices in idle mode report performance degradation events in real time, then the network can detect and respond to performance issues faster, but unnecessary signaling and resource overload occur when multiple devices report the same issues
Solution Approach 1:
Multiple wireless devices merge their performance degradation reports into a single representative report. When multiple devices experience the same performance degradation event, they coordinate to send only one report to the network node, thereby maintaining fast detection capability while significantly reducing signaling load and resource consumption.
Solution Approach 2:
The reporting mechanism serves multiple functions: it enables fast detection of performance degradation, reduces signaling overhead through coordination, and provides the network with aggregated information about network conditions. This multi-functional approach resolves the contradiction by making the reporting system adaptable to different network states.
2Quantity of substance
If wireless devices log performance degradation events for later reporting, then signaling load is reduced, but the network cannot respond to performance issues in real time
Solution Approach 1:
The reporting mechanism dynamically adapts between real-time reporting and logged reporting based on network conditions and event characteristics. When performance degradation events are critical and frequent, the system enables real-time reporting to ensure fast response. When events are less critical or signaling load is high, the system switches to logged reporting with later transmission, thereby optimizing the balance between response time and signaling load.
3Loss of information
If the network accepts all performance degradation reports from wireless devices, then complete information is obtained, but processing overload occurs at the network node
Solution Approach 1:
The system extracts and processes only representative performance degradation reports at the network node. By identifying and handling a single representative report for each unique performance degradation event, the network node avoids processing duplicate information from multiple devices, thereby maintaining information completeness while significantly reducing processing load.
