Patent number: 11917456Abstract: Systems and methods described herein use group segmentation of applications (referred to herein as “slicing classes”), based on common service requirements, to allow carriers to assign UE traffic to network slices. A UE stores slicing class definitions for use with UE Route Selection Policies (URSP). Each of the slicing class definitions include network quality of service (QoS) characteristics that are applicable to network traffic for multiple software applications. The UE maps the software applications to corresponding slicing class identifiers associated with the slicing class definitions. The UE also stores URSP rules for associating a slicing class identifier with a network slice identifier. A UE operating system sends, to a modem, one of the slicing class identifiers for an application that is requesting attachment to a wireless network. The modem sends a registration request with a selected network slice identifier based on the received slicing class identifier and the URSP rules.Type: GrantFiled: May 4, 2022Date of Patent: February 27, 2024Assignee: Verizon Patent and Licensing Inc.Inventors: Deepa Jagannatha, Bharadwaj Vemuri, Kartik P.

Patent number: 11696355Abstract: Systems and methods described herein improve a customer experience for non-standalone cellular networks by displaying a secondary cell group (SCG) network icon after data activity ends while a user device likely remains in SCG coverage. When connected to the SCG, the user device detects inactivity on the connection and initiates a first timer, based on the detecting, while continuing to present an SCG-related icon. If the first timer expires while the user device is in an idle state, the user device initiates a second timer, while continuing to present the SCG-related icon. If the user device detects an active connection before expiration of the second timer, the user device initiates a third timer while continuing to present the SCG-related icon. If the user device fails to detect a connection to the SCG before expiration of the third timer, a master cell group (MCG)-related icon is displayed.Type: GrantFiled: June 2, 2022Date of Patent: July 4, 2023Assignee: Verizon Patent and Licensing Inc.Inventors: Michael Haberman, Michael A.
