Dynamic Link Adjustment for VVoIP Call Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice and Video over Internet Protocol (VVoIP) services face challenges in maintaining low latency and high stability of data streams, particularly due to the instability of direct links and increased costs associated with relay links.
Innovation Solution
A method is introduced to assess and adjust call links for users in a network call system by determining whether to use direct or relay links based on their quality, optimizing link configuration to maximize overall call quality while controlling bandwidth and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay links are used to improve call quality stability, then call data stream stability is improved, but system costs increase
Solution Approach 1:
The system dynamically adjusts link configuration based on real-time quality assessment. Users are evaluated using a quality model that considers multiple parameters (packet loss, latency, jitter), and link types (direct vs. relay) are dynamically assigned based on current network conditions and user quality metrics, rather than using a fixed configuration for all users
Solution Approach 2:
Different link configurations are assigned to different users based on their individual quality assessments. High-quality users with good direct links continue using direct links, while low-quality users or those in congested regions are assigned relay links, allowing localized optimization rather than uniform system-wide configuration
2Loss of energy
If direct links are used to reduce costs, then system costs decrease, but call data stream stability deteriorates
Solution Approach 1:
The system implements continuous quality assessment and monitoring of call data streams. Quality metrics are collected and fed back to the link management system, which uses this feedback to make informed decisions about link configuration, ensuring that direct links are only used when quality thresholds are met
Solution Approach 2:
The system performs preliminary quality assessment and link configuration before actual call data transmission begins. Users are evaluated and assigned appropriate link types in advance, preventing quality issues during active calls and reducing the need for emergency relay link activation
3Reliability
If link quality is maximized for all users, then overall call quality improves, but bandwidth consumption increases
Solution Approach 1:
The system applies quality optimization selectively rather than universally. Instead of maximizing link quality for all users (which would consume excessive bandwidth), it applies relay link configuration only to users who fall below quality thresholds or are in congested regions, achieving sufficient quality for the majority while conserving bandwidth

AI summary
A method and apparatus are provided. The method includes obtaining call information of first users currently in network calls in a network call system. Direct link quality and relay link quality corresponding to each first user are obtained according to the call information. Call link are configured for plural second users, where the plural second users are users whose relay link quality is higher than the corresponding direct link quality among the first users.
