Solution Overview

Problem

Existing wireless communications systems lack a standardized method for configuring trigger conditions in condition-triggered cell management procedures, such as handover or secondary node management in 5G networks, leading to inefficiencies in mobility management.

Innovation Solution

A method and system for configuring trigger conditions based on an association between configuration information of a trigger condition and multiple trigger events, allowing the terminal device to determine when to initiate a radio resource control procedure for cell management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a trigger condition is configured to be associated with multiple trigger events, then the accuracy and reliability of cell management decisions are improved, but the device complexity and configuration overhead increase

Engineering Contradiction:

Improvecell management decision accuracyVSAvoidtrigger condition configuration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The trigger condition configuration is segmented into multiple independent trigger events (first trigger event, second trigger event, etc.), each with its own configuration information. This allows the system to evaluate multiple conditions separately and combine them logically, improving decision reliability while keeping each individual trigger event configuration manageable and standardized.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the network side configures trigger conditions for autonomous UE initiation, then the productivity and response speed of cell management procedures are improved, but the loss of information and configuration overhead increase

Engineering Contradiction:

Improvecell management procedure efficiencyVSAvoidconfiguration information overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The UE is empowered to autonomously evaluate trigger conditions and initiate cell management procedures based on pre-configured trigger events. The network side only needs to provide the configuration information, while the UE performs the autonomous decision-making, reducing network signaling overhead and improving response speed.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The trigger condition configuration includes specific parameters such as thresholds and event types that can be adjusted to optimize the balance between autonomous decision accuracy and configuration overhead. By carefully selecting and configuring these parameters, the system achieves efficient cell management without excessive information loss.

AI summary

A cell management method, a trigger condition configuration method, a terminal device, and a network-side device are provided. The method includes: receiving configuration information of a trigger condition and configuration information of a trigger event that are sent by a network-side device, where an association relationship exists between the configuration information of the trigger condition and the configuration information of the trigger event, and configuration information of one trigger condition is associated with configuration information of at least two trigger events; determining, based on the configuration information of the at least two trigger events associated with the configuration information of the trigger condition, whether the trigger condition is satisfied; and when the trigger condition is satisfied, initiating a radio resource control RRC procedure for cell management.
