Cellular Network Traffic Control via Unified KPI Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network-centric performance Key Performance Indicators (KPIs) in cellular networks are poorly correlated with users' experience, necessitating a method to consider user-centric KPIs for optimal network performance and user experience.
Innovation Solution
A method that continuously obtains and processes both network-centric KPIs (NW KPIs) and user-centric KPIs (UE KPIs) from access points and user equipment devices, respectively, to identify areas requiring corrective actions, enabling targeted improvements while maintaining predefined performance thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network-centric KPIs are used to monitor and optimize network performance, then network performance can be maintained within predefined thresholds, but user experience cannot be accurately reflected or improved
Solution Approach 1:
The patent merges network-centric KPIs (NW KPIs) and user-centric KPIs (UE KPIs) into a unified monitoring and optimization framework. The system collects both types of KPIs, correlates them through processing logic, and uses combined insights to identify access points requiring corrective action, thereby resolving the disconnect between network performance metrics and user experience.
Solution Approach 2:
The system establishes a feedback loop where UE KPIs (user experience data) are continuously collected, correlated with NW KPIs, and used to trigger corrective actions on access points. This feedback mechanism ensures that network optimizations are driven by actual user experience rather than solely by network-side metrics.
2Measurement precision
If corrective actions are taken to improve UE KPIs, then user experience is enhanced, but network performance may deviate from predefined thresholds
Solution Approach 1:
The system dynamically adjusts network parameters (such as transmission power, antenna tilt, azimuth) based on correlated NW KPIs and UE KPIs. By changing these parameters in a controlled manner, the system can improve user experience while maintaining network performance within acceptable thresholds through continuous monitoring and adaptive optimization.
Solution Approach 2:
The patent applies localized corrective actions to specific access points identified as requiring improvement. Rather than uniformly adjusting network parameters across the entire network, the system targets specific local areas where UE KPIs indicate poor user experience, thereby improving user experience in critical areas while minimizing impact on overall network performance.
3Productivity
If continuous monitoring of both NW KPIs and UE KPIs is implemented, then comprehensive optimization is achieved, but system complexity increases
Solution Approach 1:
The monitoring and optimization system is segmented into distinct functional components: NW KPI collection module, UE KPI collection module, correlation processing module, and corrective action execution module. This segmentation allows each component to specialize in specific tasks, making the overall complex system more manageable and easier to implement while maintaining comprehensive optimization capabilities.

AI summary
There is provided a method and system to control traffic in a cellular network comprising a plurality of access points (APs) serving a plurality of user equipment devices (UEs). The method comprises: continuously obtaining data informative of NW KPIs derived from network data related to at least part of APs; continuously obtaining data informative of one or more UE KPIs derived from user equipment data related to at least part of the UEs; and processing the one or more NW KPIs together with the one or more UE KPIs to identify AP(s) requiring corrective action. The method can further comprise enabling, with regard to the identified AP(s), desirable corrective actions to improve the UE KPIs related to the identified AP(s) whilst to keep the NW KPIs related to the identified AP(s) as matching one or more predefined thresholds.
