Solution Overview

Problem

Current methods fail to effectively detect and address temporary interferences to beams in wireless communication networks, particularly after cell site deployment, due to the temporary nature of physical obstructions, which affects user experience and communication link quality, and existing techniques are costly and inaccurate.

Innovation Solution

A traffic monitoring device that correlates traffic data across various network interfaces to identify and geolocate temporary interferences by monitoring beam measurements and user experiences, enabling real-time detection and mitigation of interference, thereby improving communication quality and conserving processing resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If drive tests and walk tests are used to identify temporary interferences, then detection capability is improved, but cost and time consumption increase significantly

Engineering Contradiction:

Core Design Contradiction:

Difficulty of detecting and measuringVSLoss of time

Solution Approach 1:

The patent uses network monitoring data and UE measurement reports as virtual copies of actual interference conditions, replacing physical drive tests and walk tests. This allows detection of temporary interferences through data analysis rather than manual field testing, significantly reducing time and cost while maintaining detection capability.

Inventive Principle:

Solution Approach 2:

The patent replaces mechanical field testing methods (drive tests, walk tests) with electronic network monitoring and data analysis systems. By substituting physical testing with automated electronic monitoring of beam measurements and traffic data, the system achieves continuous interference detection without the time and resource constraints of manual testing.

AI summary

A device may monitor traffic or a data feed associated with a user equipment (UE). The traffic or the data feed may include a set of parameters related to a temporary interference to a beam of a respective set of beams associated with the UE, a user experience of a user of the UE, or a quality of a communication link between the UE and a base station (BS), of a set of network slices used by the UE, or of a quality of (QoS) profile associated with the UE. The device may perform a first analysis related to identifying the temporary interference, a second analysis related to determining the user experience, or a third analysis related to determining the quality. The device may perform one or more actions related to addressing the temporary interference, the user experience, or the quality.
