Solution Overview

Problem

In communications networks, the VoLTE apparatus experiences high power consumption due to frequent wake-ups within the CDRX period because the maximum packaging interval does not match the CDRX period, leading to inefficient data processing and increased power usage.

Innovation Solution

The VoLTE apparatus configures a maximum packaging interval that is greater than or equal to the CDRX period and a positive integer multiple of the packaging interval, ensuring it matches the CDRX period, thereby reducing power consumption and minimizing data packet loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the maximum packaging interval is configured independently from the CDRX period, then the data packet transmission can be flexible, but the VoLTE apparatus frequently wakes up within the CDRX period increasing power consumption

Engineering Contradiction:
Improvedata packet transmission flexibilityVSAvoidpower consumption of VoLTE apparatus
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the parameter relationship between maximum packaging interval and CDRX period by establishing that the maximum packaging interval must be a positive integer multiple of the CDRX period. This parameter alignment ensures that data packet transmission intervals synchronize with the CDRX wake-up schedule, preventing unnecessary wake-ups and reducing power consumption while maintaining transmission flexibility through the integer multiple relationship.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent ensures continuous efficient operation by aligning the data packet transmission intervals with the CDRX period. When the maximum packaging interval is set as an integer multiple of the CDRX period, the system maintains continuous useful action during wake-up periods without interruption or waste, as data transmission is ready when the apparatus wakes up, eliminating idle wake-ups and maintaining operational continuity.

Inventive Principle:
Principle #20Continuity of useful action

2Use of energy by moving object

If the maximum packaging interval is set to reduce power consumption, then the VoLTE apparatus can sleep longer, but data packet loss may increase due to mismatched intervals

Engineering Contradiction:
Improvepower consumption of VoLTE apparatusVSAvoiddata packet loss
Core Design Contradiction:
Use of energy by moving objectVSLoss of substance

Solution Approach 1:

The patent resolves this contradiction by changing the parameter relationship to ensure the maximum packaging interval is a positive integer multiple of the CDRX period. This ensures that extended sleep periods do not cause packet loss, as the packaging interval aligns perfectly with wake-up cycles, guaranteeing that data is packaged and transmitted exactly when the apparatus wakes up, eliminating both unnecessary wake-ups and data loss.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements a feedback mechanism where the VoLTE apparatus determines the CDRX period configuration information and uses it to dynamically configure the maximum packaging interval. This feedback loop ensures that the packaging interval adapts to the actual CDRX period, maintaining optimal power consumption and preventing packet loss through continuous alignment adjustment based on network conditions.

Inventive Principle:
Principle #23Feedback

3Device complexity

If the maximum packaging interval is configured without considering CDRX period, then the configuration process is simple, but the relationship between data packet interval and CDRX period becomes improper

Engineering Contradiction:
Improveconfiguration process complexityVSAvoidrelationship between data packet interval and CDRX period
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent introduces a clear parameter relationship rule where the maximum packaging interval must be a positive integer multiple of the CDRX period. This simple mathematical relationship provides a straightforward configuration method that maintains stability in the relationship between data packet intervals and CDRX period, eliminating the need for complex configuration processes while ensuring proper synchronization.

Inventive Principle:
Principle #35Parameter changes
