Network Performance Information Packets for Call Quality Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony over packet networks faces challenges in managing call quality due to lack of connection path state awareness, leading to congestion, jitter, and delay issues, as well as difficulties in isolating communication problems across packet networks operated by different carriers.
Innovation Solution
A system and method that utilize performance information packets (PIP packets) to determine network performance information, including real-time and non-real-time bandwidth usage, which are communicated in-band to enable intelligent call management and network diagnostics, allowing for better handling of call processing and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telephony operates over packet networks without connection path state awareness, then network flexibility and adaptability improve, but call quality deteriorates due to congestion, jitter, and delay
Solution Approach 1:
The patent implements feedback mechanisms where network elements monitor and report connection path state information back to calling and called parties. This enables dynamic adjustment of call handling based on real-time network conditions, resolving the contradiction by providing the awareness needed to maintain call quality while preserving packet network flexibility.
Solution Approach 2:
The patent introduces intermediary network elements that act as mediators between the packet network infrastructure and the telephony service. These intermediaries collect, process, and distribute connection path state information, enabling intelligent call management without requiring changes to the underlying packet network architecture.
2Adaptability or versatility
If multiple carriers operate independent packet networks, then network independence and operational autonomy improve, but problem isolation and troubleshooting difficulty increase
Solution Approach 1:
The patent implements universal connection path state awareness mechanisms that work across multiple independent carrier networks. The same monitoring and reporting protocols operate universally across different carriers, enabling consistent problem detection and isolation while preserving each carrier's operational independence.
3Device complexity
If traditional call management is used without network performance data, then system simplicity is maintained, but intelligent call management and resource allocation cannot be achieved
Solution Approach 1:
The patent enables network elements to self-monitor and self-report their connection path state information without requiring complex external monitoring systems. This self-service approach provides the data needed for intelligent call management while minimizing additional system complexity.
