Solution Overview

Problem

Current network communication systems face challenges in effectively managing jitter, which is caused by network congestion, timing drift, and routing changes, leading to delays, packet loss, and out-of-sequence data issues, particularly in varying application scenarios such as voice and musical singing communications.

Innovation Solution

A method and device that generate trigger information to switch between two jitter control strategies based on different cached data amounts, allowing for adaptive jitter control by selecting either a first control strategy for low-delay voice communication or a second control strategy for enhanced jitter resistance and quality in musical singing scenarios, ensuring communication quality meets specific demands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single jitter control strategy is used, then the system is simple to operate, but it cannot adapt to different application scenarios (voice communication vs. musical singing)

Engineering Contradiction:

Improveadaptability to different application scenariosVSAvoidcomplexity of jitter control system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic jitter control by switching between different control strategies based on application scenarios. The system dynamically adjusts the jitter control parameter (cached data amount) according to whether the scenario is voice communication or musical singing, making the system adaptive without requiring completely separate control systems for each scenario.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the jitter control parameter (cached data amount) based on different application scenarios. For voice communication, a smaller cached data amount is used, while for musical singing, a larger cached data amount is used. This parameter adjustment allows the system to adapt to different scenarios while maintaining a unified control framework.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a larger cached data amount is used, then jitter resistance is improved, but communication delay increases

Engineering Contradiction:

Improvejitter resistanceVSAvoidcommunication delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies different cached data amounts according to local needs of different application scenarios. For voice communication where timeliness is critical, a smaller cached data amount is used to minimize delay. For musical singing where quality is prioritized, a larger cached data amount is used to enhance jitter resistance. This localized optimization resolves the contradiction by matching the caching strategy to the specific requirements of each scenario.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If fixed jitter control is used, then the control logic is simple, but it cannot respond to network condition changes

Engineering Contradiction:

Improvesimplicity of control logicVSAvoidresponse to network condition changes

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent incorporates feedback mechanisms by monitoring application scenario changes and network conditions, then switching between different jitter control strategies accordingly. The system receives feedback about the current scenario (voice or music) and adjusts the cached data amount parameter in response, maintaining simple control logic while achieving adaptive behavior through scenario-based strategy selection.

Inventive Principle:

Principle #23Feedback

AI summary

Embodiments of the application can provide a method, a device, and a terminal for controlling a jitter in network communication, belonging to the technical field of communication. The method includes: generating trigger information, where the trigger information is for triggering switching of a jitter control strategy for the network communication, the jitter control strategy includes a first control strategy based on a first cached data amount and a second control strategy based on a second cached data amount, and the first cached data amount is smaller than the second cached data amount; switching the jitter control strategy to a target control strategy in response to the trigger information; and controlling the jitter in the network communication by using the target control strategy, where the target control strategy is the first control strategy or the second control strategy corresponding to the trigger information.
