Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conditional cell management is implemented with multiple candidate cells and management commands, then cell management capability is improved, but system complexity increases

Engineering Contradiction:
Improvecell management capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates unnecessary measurement reporting steps from the conditional cell management process. By allowing the terminal to directly perform cell management operations based on pre-configured conditions without intermediate measurement reports, the solution reduces system complexity while preserving the adaptive cell management capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The network side device pre-configures multiple candidate cells and their corresponding management trigger conditions before the terminal needs to perform cell management. This preliminary configuration allows the terminal to autonomously execute cell management operations when conditions are met, reducing real-time processing complexity while maintaining versatile cell management functionality.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If measurement reporting is performed for each candidate cell, then cell selection accuracy is improved, but signaling overhead increases

Engineering Contradiction:
Improvecell selection accuracyVSAvoidsignaling overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent removes the intermediate measurement reporting step from the cell management process. The terminal uses pre-configured measurement objects and trigger conditions to directly determine cell management operations without reporting measurements to the network side device, thereby eliminating signaling overhead while maintaining cell selection accuracy through the pre-configured criteria.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The terminal autonomously performs cell management operations based on pre-configured conditions and measurement objects without requiring network side device intervention for measurement reporting. This self-service approach allows the terminal to independently make cell selection decisions, reducing signaling overhead while maintaining accurate cell selection through the pre-configured measurement criteria.

Inventive Principle:
Principle #25Self-service

3Speed

If continuous measurement and reporting is performed, then cell management responsiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvecell management responsivenessVSAvoidterminal energy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements event-triggered measurement and operation where the terminal performs measurements and cell management operations only when predefined trigger conditions are met, rather than continuously. This periodic action based on condition fulfillment maintains cell management responsiveness by acting immediately when conditions change, while significantly reducing energy consumption by avoiding continuous measurement and reporting cycles.

Inventive Principle:
Principle #19Periodic action

AI summary

A method for cell management, a terminal, and a network-side device are provided. The method for cell management applied to the terminal includes: receiving configuration information sent by the network-side device, where the configuration information includes trigger conditions for triggering a cell management operation and measurement objects; performing a measurement operation corresponding to a target trigger condition on a target measurement object, to obtain a measurement result; if the measurement result satisfies the target trigger condition, performing a management operation on a target cell, where the target measurement object is any one of the measurement objects included in the configuration information, and the target trigger condition is associated with the target measurement object.
