Measurement Reporting Policy for Consolidated UE RRM Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio resource management (RRM) policies in communication systems lead to inappropriate decisions due to redundant reporting and signaling storms, particularly when user equipment (UE) reports measurement results out of sequence, resulting in unnecessary handovers and inefficient resource allocation.
Innovation Solution
A communication method and apparatus that optimizes measurement policies by introducing a first identity with associated second identities, allowing unified reporting of measurement results within a defined period, and includes criteria for reporting based on specific conditions and thresholds, thereby reducing redundant reporting and improving decision-making by network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the UE reports measurement results immediately when trigger conditions are met, then the network device can respond quickly, but redundant reporting occurs and signaling storms are caused
Solution Approach 1:
The network device configures a measurement period in advance for each measurement identity. The UE uses this pre-configured period to determine when to report, avoiding immediate reporting that causes signaling storms while still enabling timely network response.
Solution Approach 2:
Instead of immediate reporting upon trigger condition met, the UE reports measurement results periodically based on the configured measurement period. This periodic reporting mechanism filters out redundant immediate reports and prevents signaling storms while maintaining effective network device awareness.
2Loss of information
If the UE reports measurement results for all measurement identities, then complete information is provided, but redundant reporting occurs when serving cell does not change
Solution Approach 1:
The patent extracts and reports only the measurement results of non-serving cells when the serving cell does not change. This selective reporting approach maintains information completeness for relevant measurements while eliminating redundant reports of the serving cell, reducing overall signaling overhead.
Solution Approach 2:
Different reporting strategies are applied to different measurement identities based on their local characteristics. The UE determines whether to report based on whether the measurement identity corresponds to a serving cell or a non-serving cell, applying selective reporting quality to each local measurement context.
3Reliability
If multiple measurement identities meet trigger conditions simultaneously, then comprehensive measurement coverage is achieved, but signaling overhead increases
Solution Approach 1:
The patent merges multiple measurement reports into a single consolidated report when multiple measurement identities meet trigger conditions within the same measurement period. This combining approach maintains comprehensive measurement coverage while significantly reducing signaling overhead by transmitting one report instead of multiple separate reports.
Solution Approach 2:
The measurement report structure is designed to be universal, accommodating multiple measurement identities and their results within a single report framework. This multi-functional report format allows the UE to report on multiple measurement contexts simultaneously without proportionally increasing signaling overhead.

AI summary
A communication method and apparatus to optimize a measurement policy are described. The apparatus may receive a measurement configuration sent by a network device. The measurement configuration may include a first identity and a first period of the first identity. The apparatus sends a measurement report to the network device when the first period expires. The measurement report may include the first identity and a measurement result of the first identity. The measurement result of the first identity includes a measurement result of at least one second identity.
