Solution Overview

Problem

Measurement reporting for false base station detection imposes a significant load and impact on wireless devices, threatening service continuity and increasing power consumption.

Innovation Solution

Network equipment configures different sets of wireless devices to report different measurements, distributing the reporting load across multiple devices, and allows individual devices to autonomously decide whether to apply the reporting configuration based on certain rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If measurement reporting is configured for false base station detection, then false base station detection capability is improved, but power consumption increases and service continuity deteriorates

Engineering Contradiction:

Improvefalse base station detection capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network divides the set of measurements to be reported into multiple subsets, and configures different wireless devices to report different subsets. This segmentation distributes the measurement reporting load across multiple devices, reducing the power consumption and service impact on any single device while maintaining overall detection capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different wireless devices are assigned different measurement reporting configurations based on their local characteristics or network decisions. Each device reports a specific subset of measurements tailored to its configuration, optimizing the balance between detection effectiveness and individual device power consumption.

Inventive Principle:

Principle #3Local quality

2Reliability

If measurement reporting frequency and content are increased for false base station detection, then detection effectiveness is improved, but load on wireless devices increases

Engineering Contradiction:

Improvefalse base station detection effectivenessVSAvoidmeasurement reporting load

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The comprehensive set of measurements required for false base station detection is segmented into multiple subsets. Each wireless device is configured to report only its assigned subset, distributing the reporting complexity and load across multiple devices rather than requiring each device to handle the full measurement set.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each wireless device performs and reports only a partial set of measurements rather than the complete set. This partial action approach reduces the complexity and load on individual devices while the aggregate data from multiple devices provides sufficient information for effective false base station detection.

Inventive Principle:

Principle #16Partial or excessive action
