Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telephony users face unsatisfactory call routing due to the proliferation of user devices and access technologies, leading to inconsistent voice quality and increased network loading, with existing methods failing to effectively select the best media routing path based on real-time media quality.
Innovation Solution
A method involving a call control system that performs media quality tests across multiple media routing paths, including circuit-switched and packet-switched networks, to select the optimal path for call routing based on analyzed data, ensuring better voice quality and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple media routing paths are available for call communication, then adaptability and versatility are improved, but device complexity and difficulty of detecting and measuring increase
Solution Approach 1:
A call control system acts as an intermediary between the user and multiple media routing paths. The system automatically performs media quality tests, analyzes results, and selects the optimal routing path without requiring user intervention or manual configuration, thereby managing complexity while maintaining routing flexibility
Solution Approach 2:
The system implements feedback mechanisms by continuously performing media quality tests on available routing paths and using the test results to dynamically select the best path for call routing, ensuring adaptability while automating the complexity management
2Measurement precision
If media quality test procedures are performed across multiple routing paths, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The call control system performs media quality tests in advance before actual call routing decisions are made. By pre-assessing the quality of multiple routing paths and maintaining this information, the system reduces the time required for routing decisions while ensuring accurate media quality measurement
Solution Approach 2:
The system performs media quality tests on a selective basis rather than continuously monitoring all paths at all times. Testing is triggered by specific events such as call setup requests or periodic intervals, balancing measurement precision with time efficiency
3Productivity
If automatic media quality-based routing selection is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The call control system automatically performs media quality tests, analyzes results, and makes routing decisions without requiring external intervention. The system serves itself by managing the complexity of multiple routing paths through automated quality assessment and selection, improving routing efficiency while encapsulating complexity within the control system

AI summary
A method of routing a call involving a call party in a telecommunications network via a selected media routing path of a plurality of different media routing paths is provided. The media routing paths communicate media data to and/or from at least one communication device associated with the call party. A call control system in the telecommunications network receives data derived from a media quality test procedure for a given media routing path. The media quality test procedure includes media test data being communicated via the given media routing path and the media test data being analysed. The call control system selects a preferred media routing path from the plurality of media routing paths for communicating media data associated with the call to and/or from one or more of the at least one communication devices associated with the call party on the basis of at least the received data.
