Solution Overview

Problem

Existing wireless communication systems face challenges in configuring wireless devices to report cell global identifiers (CGI) without flushing their records of measurements performed on measurement objects, leading to inefficient data reporting and potential delays in handover processes.

Innovation Solution

The proposed solution involves configuring wireless devices to selectively maintain or reset their measurement records based on specific updates to measurement objects, and using explicit control signaling or adding new measurement reporting configurations/identities to prevent record flushing while enabling CGI reporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network node updates the measurement object to configure CGI reporting, then the wireless device can report CGI for the cell, but the measurement records performed on that measurement object are flushed

Engineering Contradiction:

ImproveCGI reporting capabilityVSAvoidmeasurement records

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent segments the measurement configuration into separate components: measurement objects (for measurement records) and measurement reporting configurations (for CGI reporting). This allows independent management of each component, enabling CGI reporting without flushing measurement records. The measurement reporting configuration includes a reporting cell identity and measurement identity, while the measurement object maintains its measurement records separately.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a measurement reporting configuration as an intermediary mechanism between the network node and wireless device for configuring CGI reporting. This intermediary structure allows the network to request CGI reports without directly modifying the measurement objects that contain measurement records, thus preventing record flushing while enabling reporting functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the network node updates the measurement object to enable CGI reporting, then the wireless device reports CGI, but handover processes experience delays due to unnecessary data flushes

Engineering Contradiction:

ImproveCGI reportingVSAvoidhandover processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By separating measurement reporting configuration from measurement object updates, the patent eliminates unnecessary flush operations. The measurement reporting configuration can be updated independently to enable CGI reporting, while measurement objects retain their records without flushing, thereby preventing handover delays.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter structure by introducing a measurement reporting configuration with specific fields (reporting cell identity, measurement identity) that can be modified without affecting the measurement objects. This parameter separation allows CGI reporting to be enabled through configuration changes rather than object updates, avoiding the side effect of flushing measurement records.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the network node uses existing measurement reporting configuration to configure CGI reporting, then the device can report CGI, but the measurement records are lost due to flush operation

Engineering Contradiction:

ImproveCGI reporting configurationVSAvoidmeasurement records

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent creates a distinct measurement reporting configuration structure that is separate from the measurement object. This segmentation allows the network node to configure CGI reporting through the reporting configuration without touching the measurement object, thereby preserving measurement records while enabling easy CGI reporting setup.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses a measurement reporting configuration that copies the measurement identity linkage but adds specific reporting parameters (reporting cell identity, measurement identity) that enable CGI reporting without replicating the measurement object's flush behavior. This copying approach allows reporting functionality to be added without replicating the harmful flush operation.

Inventive Principle:

Principle #26Copying

AI summary

A wireless device (111) is configured to receive, from a network node (101), in a measurement reporting configuration information element (127) of a measurement configuration or a measurement identity information element (129) of a measurement configuration, an indication (128) of for which cell the wireless device (111) (111) is to report a cell global identifier, CGI. In embodiments in which the indication (128) is received in the measurement reporting configuration information element (127), for instance, the wireless device (111) may add a reporting configuration indicated by that information element to a list of reporting configurations at the wireless device (111), e.g., as opposed to updating an existing reporting configuration. Regardless, the wireless device (111) may also be configured to report a CGI for the cell indicated by the received indication (128).
