Patent number: 11785492Abstract: An anomaly detection and analysis system generates analysis or summary of the anomalies detected from key performance indicators (KPIs). The system receives anomaly data reporting anomalies detected in key performance indicator (KPI) data. The system classifies the reported anomalies into a plurality of anomaly items, wherein anomalies from KPI data that share a set of features are assigned to one anomaly item. The system computes a ranking score for each anomaly item by assigning predefined weights for different anomaly types that are present in the anomaly item. The system sorts a list of anomaly items from the plurality of anomaly items into a sorted list of anomaly items according to the ranking scores computed for the plurality of anomaly items. The system sends the sorted list of anomaly items to a user device for presentation.Type: GrantFiled: November 29, 2021Date of Patent: October 10, 2023Assignee: T-Mobile USA, Inc.Inventors: Prem Kumar Bodiga, Ariz Jacinto, Chuong Phan, Amer Hamdan, Dung Tan Dang, Sangwoo Han, Zunyan Xiong

Patent number: 11599673Abstract: Techniques for identifying certain types of network activity are disclosed, including parsing network traffic to automatically recognize anonymous identifiers. Such techniques may be used to identify and eliminate malicious and/or undesirable network traffic, and to identify topics relevant to a user of a particular network device so that communications to such a user are more likely to relate to a topic of interest to the user.Type: GrantFiled: July 17, 2020Date of Patent: March 7, 2023Assignee: T-Mobile USA, Inc.Inventors: Rami Al-Kabra, Prem Kumar Bodiga, Noah Dahlstrom, Ruchir Sinha, Jonathan Morrow, Aaron Drake, Chuong Phan

Patent number: 11561960Abstract: An anomaly detection and analysis system detects anomalies in time series data from key performance indicators (KPIs). The system decomposes samples of the time series data received during a first time interval into a trend component, a seasonality component, and a randomness component. The system identifies an upper bound and a lower bound based on the trend component, the seasonality component, and a variance of the randomness component. The system reports a sample received after the first time interval as an anomaly when the sample exceeds the upper bound or the lower bound. The system recalculates the trend component, the seasonality component, and the randomness component when more than a threshold percentage of the samples of the time series data received during a second time interval are reported as being anomalous.Type: GrantFiled: August 13, 2019Date of Patent: January 24, 2023Assignee: T-Mobile USA, Inc.Inventors: Ariz Jacinto, Zunyan Xiong, Chuong Phan, Amer Hamdan, Sangwoo Han, Prem Kumar Bodiga, Dung Tan Dang

Patent number: 11537751Abstract: Techniques for identifying certain types of network activity are disclosed, including parsing of a Uniform Resource Locator (URL) to identify a plurality of key-value pairs in a query string of the URL. The plurality of key-value pairs may include one or more potential anonymous identifiers. In an example embodiment, a machine learning algorithm is trained on the URL to determine whether the one or more potential anonymous identifiers are actual anonymous identifiers (i.e., advertising identifiers) that provide advertisers a method to identify a user device without using, for example, a permanent device identifier. In this embodiment, a ranking threshold is used to verify the URL. A verified URL associate the one or more potential anonymous identifiers with the user device as actual anonymous identifiers. Such techniques may be used to identify and eliminate malicious and/or undesirable network traffic.Type: GrantFiled: October 22, 2020Date of Patent: December 27, 2022Assignee: T-Mobile USA, Inc.Inventors: Rami Al-Kabra, Douglas Galagate, Eric Yatskowitz, Chuong Phan, Tatiana Dashevskiy, Prem Kumar Bodiga, Noah Dahlstrom, Ruchir Sinha, Jonathan Morrow, Aaron Drake
