INTER-CORE TRANSPORT AUDIO QUALITY TESTING REMOTE FROM TESTING SITE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015536 titled 'INTER-CORE TRANSPORT AUDIO QUALITY TESTING REMOTE FROM TESTING SITE

Simplified Explanation

The patent application describes a technology for testing the audio quality of a transport segment between two core networks. It involves the use of virtual test agents (VTAs) and mobility management engines (MMEs) to route calls and evaluate audio quality over the transport segment.

  • A first VTA selects an MME corresponding to an enodeb served by a first core network for routing a second call.
  • The second call is made from the first VTA to a second VTA at a second core network over a transport segment under test.
  • The first VTA makes a first call to a tester appliance and then makes a second call to the second VTA for audio evaluation.
  • The first and second calls are bridged by the first VTA to relay audio during the test of subjective audio quality.

Potential applications of this technology:

  • Testing and evaluating audio quality in telecommunications networks.
  • Assessing the performance of transport segments between core networks.
  • Quality assurance and troubleshooting in audio communication systems.

Problems solved by this technology:

  • Provides a method for objectively testing and evaluating audio quality over transport segments.
  • Enables efficient routing of calls between core networks for audio evaluation.
  • Facilitates the identification and resolution of audio quality issues in telecommunications networks.

Benefits of this technology:

  • Allows for accurate assessment of audio quality in real-world network conditions.
  • Provides a standardized and automated approach to audio quality testing.
  • Helps improve the overall user experience in audio communication systems.


Original Abstract Submitted

the technology includes a method, computer medium, and system for testing audio quality of a transport segment between two core networks. a first virtual test agent (vta) selects a mobility management engine (mme) corresponding to an enodeb served by a first core network for routing a second call, through a serving gateway (sgw) assigned by the mme for audio communication with a tester terminus. the second call is made from the first vta to a second vta at a second core network over a transport-segment-under-test that connects the first and second core networks, so that a tester can evaluate audio quality over the transport-segment-under-test. the first vta makes a first call to a tester appliance, makes a second call, over the transport-segment-under-test, to the second vta implementing audio evaluation, by signaling the mme, and bridges the first and second calls by relaying audio during a test of subjective audio quality.
