Solution Overview

Problem

In wireless communication systems, measurement reports from terminals are often not transmitted to the network due to power management or other reasons, leading to suboptimal network performance and degraded service quality, as the network lacks essential data for optimization and mobility management.

Innovation Solution

A method where terminals store suppressed measurement reports and aggregate them during allowed reporting periods, transmitting aggregated results to the network, which includes configuring measurement identities, reporting configurations, and using DRX operations to manage power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If terminals suppress measurement report transmission due to power management, then terminal power consumption is reduced, but network performance and service quality deteriorate due to lack of measurement data

Engineering Contradiction:
Improveterminal power consumptionVSAvoidnetwork performance
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The terminal performs measurements and stores measurement results in advance during periods when reporting is suppressed, so that when reporting is allowed, the accumulated measurements can be transmitted together. This preliminary accumulation of data resolves the contradiction by preparing information beforehand without requiring continuous transmission, thus saving power while ensuring network performance is not degraded.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The measurement result buffer acts as an intermediary storage mechanism between the measurement function and the reporting function. It temporarily holds measurement results that cannot be transmitted immediately, allowing the system to decouple the measurement process from the reporting process. This intermediary buffer enables power management to suppress reporting while preserving measurement data for later transmission, resolving the contradiction between power saving and network performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If terminals frequently transmit measurement reports to the network, then network optimization and mobility management improve, but terminal power consumption increases

Engineering Contradiction:
Improvenetwork optimizationVSAvoidterminal power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous or frequent measurement report transmission, the system implements periodic reporting where measurements are accumulated over multiple periods and transmitted at designated reporting opportunities. This periodic action reduces the frequency of transmission events, thereby lowering terminal power consumption while still providing the network with sufficient measurement data for optimization and mobility management decisions.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Multiple individual measurement results that would otherwise be transmitted separately are merged and combined into a single aggregated report. By combining multiple measurements into one transmission event, the terminal reduces the number of separate transmission operations, thereby reducing power consumption while delivering comprehensive measurement data to the network for effective optimization.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If terminals store multiple measurement results for later aggregation, then transmission efficiency improves and power consumption reduces, but terminal memory usage increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidterminal memory usage
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system changes the parameter of measurement data representation by filtering, selecting, or compressing which measurement results are stored in the buffer. Instead of storing all raw measurement data, the terminal applies parameter changes such as storing only relevant measurements, aggregated statistics, or filtered results that meet certain criteria. This reduces the quantity of data requiring storage while maintaining transmission efficiency and enabling effective aggregation when reporting occurs.

Principle #35Parameter changes
