Patent number: 11916751Abstract: Examples for analyzing the usage of virtualized network instances within a communication network, are described. In an example, a usage monitoring service may receive a data change notification from a unified data repository. The data change notification is generated by the unified data repository in response to a data modification in subscriber data of a virtualized network instance. In an example, the data modification retrieved from the generated data change notification is utilized to obtain usage indication information for the virtualized network instance.Type: GrantFiled: October 11, 2022Date of Patent: February 27, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Alain Guigui, Sebastien Klahr, Ravi Saxena

Patent number: 11882013Abstract: Example implementations relate to changing a status of a device responsive to detecting an anomaly. A traffic pattern of a device may be monitored across a network. It may be determined that the monitored traffic pattern deviates from an expected traffic pattern of the group of devices by a threshold. Responsive to determining that the devices deviates from the expected traffic pattern, packet data transmitted by the device may be inspected. It may be determined that the inspected packet data transmitted by the device is anomalous. The status of the device may be changed responsive to determining that the packet data transmitted by the device is anomalous.Type: GrantFiled: October 2, 2021Date of Patent: January 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: John O'Connell, Ravi Saxena, Bo Wang

Patent number: 11696098Abstract: Systems and methods define an enhanced charging function (CHF) in a communication network by creating a type of slice analysis functionality. For example, the system can access slice information from multiple Policy Control Functions (PCFs) and determine analytics for multiple slices associated with a subscriber user/device or group of subscriber users/devices. Using the enhanced CHF, the system can trigger slice level decisions at a higher level of the hierarchy based on information being aggregated for family devices/plans, category, quota, usage, or other groupings at the CHF instead of just at the individual slice level (e.g., similar to standard PCF functionality).Type: GrantFiled: March 4, 2021Date of Patent: July 4, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Ravi Saxena, Bo Wang

Publication number: 20230035224Abstract: Arrays of integrated analytical devices are provided. The arrays are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. In particular, the arrays provide increased efficiency of optical collection and decreased background signal as the lateral dimensions of the unit cell of devices within the array are decreased, for example as they are decreased to 2 ?m, or even less.Type: ApplicationFiled: May 4, 2022Publication date: February 2, 2023Inventors: Hans CALLEBAUT, Mark MCDONALD, Arghavan ARJMAND, Annette GROT, Mathieu FOQUET, Ravi SAXENA, Michael Tzu RU

Patent number: 11546833Abstract: 5G introduces the concept of network slices. Although the 5G standard contemplates some form of slice access control, it is premised on subscriber identity-based checks. Because subscriber identities are associated with/maintained via subscriber identity module (SIM) cards, and because SIM cards can be swapped from one device (user equipment) to another, slice access control based on subscriber identities can fail to prevent unauthorized device access. Systems and methods are provided for enhanced slice access control vis-à-vis an enhanced access and mobility management (AMF), and equipment identity register (EIR) functions. In some embodiments, a localized EIR function can reduce latency/messaging overhead.Type: GrantFiled: March 18, 2021Date of Patent: January 3, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Ravi Saxena, John O'Connell
