  • Patent number: 11916751
    Abstract: 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.

  • Patent number: 11882013
    Abstract: 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.

  • Publication number: 20230314325
    Abstract: Arrays of integrated analytical devices and their methods for production 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. The devices allow the highly sensitive discrimination of optical signals using features such as spectra, amplitude, and time resolution, or combinations thereof. The devices include an integrated diffractive beam shaping element that provides for the spatial separation of light emitted from the optical reactions.

  • Patent number: 11696098
    Abstract: 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).

  • Publication number: 20230035224
    Abstract: 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.

  • Patent number: 11546833
    Abstract: 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.
