  • Publication number: 20220311687
    Abstract: A processing system may generate segments of network infrastructure items deployed in a communication network, each segment comprising network infrastructure items grouped in accordance with segment filters and a segment size sparsity threshold, and identify anomalous segments comprising at least a subset of the segments having anomalies of an anomaly type regarding a performance indicator. The processing system may next determine segments from the subset that are defined by sets of segment filter values that are different for less than a threshold number of segment filters, merge the segments from the subset that are different for less than the threshold number to create at least one aggregate segment, and generate a ranking of the subset having the anomalies of the anomaly type, wherein the ranking includes the at least one aggregate segment. The processing system may then perform at least one action in the communication network responsive to the ranking.

  • Publication number: 20220303227
    Abstract: Facilitating identification of background browsing traffic in browsing history data in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a system can include, based on browsing history traffic observed with respect to a group of user equipment, constructing labeling functions for a group of domains associated with the browsing history traffic, producing a group of labels based on the labeling functions, and transforming the group of labels into a single consolidated label for a first domain. Further, the operations can include, based on a determination that a first numeric value of the single consolidated label is nearer to a first value than a second value, scheduling first traffic for the first domain prior to scheduling traffic for a second domain determined to include the second numeric value that is nearer the second value than the first value.

  • Publication number: 20220264185
    Abstract: Aspects of the subject disclosure may include, for example, a system or method that collects or otherwise accesses information indicating connection patterns such as IP addresses being utilized by communication devices for communication services over a time period, where the communication devices use a same credential of a single account for accessing the communication services. Hubs can be identified according to groups of the communication devices that exhibit a particular sharing pattern such as having used the one or more common IP addresses. A prediction or estimation that the single account is engaging in sharing activity can be made based on an analysis of the hubs, such as based on a number of the hubs. Other embodiments are disclosed.

  • Publication number: 20220109309
    Abstract: A system for suppressing inrush currents is described. The system may include a negative temperature coefficient (NTC) thermistor and a positive temperature coefficient (PTC) thermistor arranged in series between a power source and a battery system to be charged. At a low temperature, while the PTC thermistor provides only minimal resistance to minimize an inrush current, the NTC thermistor provides increased resistance. As the temperature increases, the resistance provided by the PTC thermistor increases as the resistance from the NTC thermistor decreases. The system may be used in conjunction with a battery charging system has at least one current pathway from the power source to the battery system.
