Centralized Network Performance Tables for Packet Call Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony systems over packet networks face challenges in managing call quality due to lack of connection path state awareness, leading to issues with congestion, jitter, and delay, as well as difficulties in isolating communication problems across packet networks, especially in converged networks carrying real-time and non-real-time traffic.
Innovation Solution
Centralizing network performance information to enable call control managers to monitor bearer path and link status in real-time, using performance information packets (PIP packets) to collect and manage network performance data across node segments, allowing for better call handling and quality management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If packet networks are used to carry telephony traffic, then network flexibility and convergence of services are improved, but call quality management deteriorates due to lack of connection path state awareness
Solution Approach 1:
The patent implements feedback mechanisms where network performance information is continuously collected from node segments and fed back to call control managers. This enables dynamic adjustment of call characteristics based on actual network conditions, resolving the contradiction by providing the missing connection path state awareness in packet networks.
Solution Approach 2:
The patent introduces performance information packets (PIPs) as intermediaries that carry network performance data between network nodes and call control managers. These PIP packets serve as the mediator that bridges the gap between packet network operations and call quality management, enabling reliable call quality control while maintaining network convergence.
2Reliability
If centralized monitoring of network performance is implemented, then call quality management is improved, but system complexity increases
Solution Approach 1:
The patent enables network nodes to automatically generate and send performance information packets without requiring complex centralized collection mechanisms. Each node self-monitors its performance and contributes data to the centralized table, reducing the complexity of the monitoring system while maintaining reliable call quality management.
Solution Approach 2:
The centralized performance information table serves multiple functions: it stores network performance data, enables call routing decisions, supports quality management, and provides a basis for proactive adjustments. This multi-functionality reduces the need for separate systems for each function, thereby reducing overall system complexity.

AI summary
A system for centrally controlling packet network communications may include an input/output (I/O) unit configured to communicate data packets over a packet network with multiple network communications devices, a processing unit in communication with the I/O unit and configured to communicate with the network communications devices via respective node segments, and a memory in communication with the processing unit and configured to store a table. The processing unit may be configured to receive and store network performance information of node segments generated by the network communications devices. The network performance information may be stored in the table in association with indicia representative of the node segments, respectively. The processing unit may further be configured to control network communications by the network communications devices over the node segments based on the network performance information stored in the table.
