Selective Measurement Report Stopping in Radio Access Networks

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current X2AP specifications in 3GPP TS36.423 do not allow for efficient stopping of specific measurement reports for certain cells and information types, leading to unnecessary stopping of all measurements and increased signaling overhead.

Innovation Solution

The proposed solution involves using a request message with specific fields to selectively stop measurement reports for specific cells and information types, allowing for a subset or all cells and information types to be stopped based on actual requirements, thereby reducing unnecessary signaling and maintaining continuity of relevant reports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the current X2AP specification uses a request message to stop measurement reports, then all measurement reports for all cells are stopped, but this causes unnecessary signaling overhead and loss of relevant measurement data

Engineering Contradiction:

Improvemeasurement report continuityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments the measurement report stopping function by introducing a cell list field in the request message, allowing the network to stop measurements for only specific cells rather than all cells. This segmentation enables selective stopping of measurement reports based on actual needs, preventing unnecessary signaling overhead while maintaining continuity of relevant measurements for other cells.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements partial action by allowing the request message to specify only the subset of cells for which measurement reports should be stopped. Instead of stopping all measurements (excessive action), the system stops only the necessary portion (partial action) for cells that no longer need measurement reporting, thereby reducing signaling overhead while preserving relevant measurement data for other cells.

Inventive Principle:

Principle #16Partial or excessive action

2Ease of operation

If separate request messages are sent to start and stop measurements for different cells, then precise control is achieved, but signaling overhead increases

Engineering Contradiction:

Improvemeasurement control flexibilityVSAvoidsignaling overhead

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent merges the start and stop measurement control functions into a single request message by introducing both a cell list field for stopping and a report characteristics field for starting. This merging allows the network to perform both start and stop operations in one message, maintaining precise control over measurement reports for different cells while significantly reducing signaling overhead compared to sending separate messages for each operation.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present disclosure provides a method of requesting for a measurement report, comprising steps of: setting, in a request message, a first field for indicating an action on measurement to be stop and a second field including cell information for which a stop action on measurement is needed, so as to indicate a reporting eNB to stop measurement reports according to the second field; and transmitting to the reporting eNB the request message for the measurement report. The present disclosure also provides a requesting eNB using the above method, a method of stopping a measurement report by a reporting eNB and a reporting eNB using the above method, as well as a computer readable recording medium comprising computer instructions for executing the above methods.
