Patent number: 11995978Abstract: Emergency alert systems and methods for disabled and/or differently abled persons are disclosed. Upon receiving an alert message, the system translates the alert message to an audio message (text to speech) when the text to speech feature is enabled. In some implementations, the system waits fora threshold period of time (e.g., 30 seconds) to receive a user acknowledgment of the alert message, and translates the alert message to an audio message if no acknowledgment is received within this time. The user acknowledgment can be received via a selection of an option (e.g., by clicking an “OK” button) and/or via an audio option (e.g., by saying “Ok, received”) when the text to speech feature is enabled. The system then outputs (e.g., reads out loud) the translated message so that the disabled or differently abled persons can be informed of the emergency situation. After outputting the translated message, the system can further wait for a user acknowledgment of the translated audio message.Type: GrantFiled: July 28, 2021Date of Patent: May 28, 2024Assignee: T-Mobile USA, Inc.Inventor: Wei-Ming Lan

Patent number: 11997554Abstract: System and methods for smart cell selection and reselection are described. A mobile device may attempt to camp on a cell in a tracking area that has advertised a particular frequency band. If the mobile device is unable to recognize an information element identifying a different subset of the advertised frequency band than that supported by the mobile device, the mobile device will store a record of the tracking area and the advertised frequency band and compare future cell information broadcasts to the entry, avoiding attempts to operate within cells in the same tracking area advertising the same frequency. In this way the mobile device conserves resources by avoiding actions in incompatible cells and avoids storing information about many cells by only storing the tracking area information.Type: GrantFiled: March 30, 2022Date of Patent: May 28, 2024Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Egil Gronstad, Alan Denis MacDonald, Scott Francis Migaldi, John Humbert, Brett L.

Patent number: 11985573Abstract: Methods and systems for reporting zero usage for immediate trigger types are discussed herein. According to an implementation a communication session is established between a user equipment (UE) and the 5G network to provide service/content requested by the UE. A session management function (SMF) may receives a message from the UE to report the usage of one or more data units granted to the UE. The message indicates that an event occurs during a zero-usage time period. The SMF determines whether the event triggers a charging condition. When the event triggers a charging condition that needs to be reported immediately, the SMF sends a charging data request to a charging function (CHF) to report the event, regardless the one or more data units have zero-usage.Type: GrantFiled: September 29, 2021Date of Patent: May 14, 2024Assignee: T-Mobile USA, Inc.Inventor: Robert L.
