Filed:

Jul 2, 2010

Appl. No.:

12/830142

Inventors:

Venkataraman Natarajan - Bellevue WA, US
Arun Ananth Bhatji - Bellevue WA, US
Mathew Samuel - Renton WA, US
David Ross Jenkinson - Auburn WA, US

Assignee:

T-MOBILE USA, INC. - Bellevue WA

International Classification:

H04W 72/00

US Classification:

455450

Abstract:

A switching matrix and testing platform may enable controlled testing of various configurations of radio access networks (RANs) at various signal strengths. The switching matrix and testing platform may enable testing of the radio frequency (RF) signals from RANs or telecommunications devices for new and/or predetermined scenarios, such as using different configurations of the RANs at various signal strengths. During a scenario, various operations may be performed on the telecommunications device in communication with the tested RF signals, such as making voice calls, transmitting and receiving data (messages, videos, music, etc.). A performance of the telecommunications device and/or various telecommunication network elements may be analyzed in comparison to other telecommunications device and/or various telecommunication network elements.

Appl. No.:

13/649818

Inventors:

T-Mobile USA, Inc - Bellevue WA, US
Mohamad F. Ezzeddine - Kirkland WA, US
Mathew Samuel - Renton WA, US

Assignee:

T-MOBILE USA, INC - Bellevue WA

International Classification:

G06F 13/12

US Classification:

703 21

Abstract:

Techniques for calculating quality of user experience (QoE) scores for video streams as played on receiving devices are described herein. Prior to calculating a QoE score, a device receives a video of a display screen of a receiving device captured while the receiving device plays a video stream. The device also receives transmission metrics from at least one device engaged in the transmission of the video stream to the receiving device. The device then calculates the QoE score for that received video based at least in part on a reference video, the transmission metrics, and one or more QoE models. Additionally, prior to receiving the video or the transmission metrics, the device may automate the transmission of the reference video as the video stream from a sending device to the receiving device over at least one network emulator, including providing network impairment settings to the network emulator.

Inventors:

- Redmond WA, US
Mathew SAMUEL - Renton WA, US

Assignee:

Airometric Wireless Inc. - Redmond WA

International Classification:

H04W 24/00

US Classification:

455 6714

Abstract:

Services and applications running on devices placed in live wireless environments are tested and reported to determine the relative performance of the device under test. Multiple logs collected from the device under test are combined and transmitted to a remote backend system. The backend system stores and analyzes the combined logs to generate reports containing factual and relative performance information regarding the device during the testing period. The nature of the test, the collected log information, and the report format may all be modified according to the criteria of the requestor.
