Solution Overview

Problem

Current wireless communication systems face challenges in reducing the impact of measurement processes on user equipment (UE) performance while ensuring timely provision of measurement results to the network side, particularly due to unnecessary measurements and call setup delays caused by blind RAT relocation indications and frequent measurement reporting.

Innovation Solution

A measurement control method and device configuration where the UE receives measurement indication information from the network side, determining whether to perform measurements based on load-related or service-related indications, and only conducts pertinent measurements, reducing frequency and impact on performance by setting measurement periods and report criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE performs IRAT measurement before sending RRC connection request message, then the RAT relocation indication is no longer blind, but the call setup delay is extended

Engineering Contradiction:

ImproveRAT relocation accuracyVSAvoidcall setup delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The UE performs IRAT measurement in advance before sending the RRC connection request message, so that measurement results are ready when needed for potential RAT relocation decisions by the network side

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The UE performs measurement unconditionally before each call setup, even though not all call setups will result in RAT relocation, ensuring measurement data is available when needed

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If the UE performs measurement and reporting each time before sending RRC connection request message, then the network side has measurement data for relocation decision, but unnecessary measurements and reports are made

Engineering Contradiction:

Improvemeasurement data availabilityVSAvoidunnecessary measurement and report tasks

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The network side sends measurement indication information to the UE to trigger measurements only when relocation is actually needed, creating a feedback-based measurement control mechanism

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The UE autonomously determines whether to perform measurement based on receiving measurement indication information from the network side, eliminating unnecessary measurements

Inventive Principle:

Principle #25Self-service

3Extent of automation

If the UE performs additional measurements for automatic network configuration and optimization, then the network side obtains measurement data for optimization, but the UE performance is further impacted

Engineering Contradiction:

Improvenetwork configuration and optimizationVSAvoidUE performance

Core Design Contradiction:

Extent of automationVSProductivity

Solution Approach 1:

The network side controls additional measurements for optimization purposes by sending measurement indication information, allowing automated network configuration while minimizing UE burden

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The UE performs additional measurements only when triggered by network indication, providing necessary data for network optimization without continuously impacting UE performance

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A measurement control method is disclosed. A user equipment (UE) receives measurement indication information from a network and initiated by the network. The measurement indication information includes an identification of an area of a current cell where the UE is located. The UE determines whether the identified area is within a preferred area of the UE. The UE performs a measurement process if the identified area is not within a preferred area of the UE.
