Method for testing audio quality regardless of tester location
The patent application (Publication Number: US20240015245A1) describes a method for testing transport audio quality regardless of the tester's location. The method involves a virtual test agent (VTA) selecting a Mobility Management Engine (MME) corresponding to an eNodeB in a core network-served physical location. The VTA routes a second call through a Serving Gateway (SGW) assigned by the MME for audio communication with a tester terminus over the transport segment being tested. This allows the tester to evaluate audio quality by bridging the first and second calls, ensuring that relayed audio in the second call continues over the transport segment under test without being rerouted by core network components.
Furthermore, the patent application includes claims related to the tester appliance being remote from the VTA and the transport segment, the tester terminus interacting with the tester appliance, and the tester being a person conducting the audio quality test. The method also covers scenarios where the relayed audio is generated by either the person or a computer program and evaluated at the tester terminus. Additionally, the application extends to non-transitory computer-readable storage mediums and systems implementing the method, emphasizing the flexibility and effectiveness of the proposed approach in testing transport audio quality regardless of the tester's location.
