ANOMALY DETECTION FOR VIRTUALIZED RANS

To meet the stringent 5G radio access network (RAN) service requirements, layers one and two need to be processed in essentially real time. Thus, prompt anomaly detection is important to prevent negative impacts on customer experience, which is critical for mobile networks to meet the stringent service requirements. However, monitoring networks for anomalies is difficult due at least to (1) the resource constrained edge deployments in which the vRAN resides, (2) the variety of anomaly types and fault locations making anomalies difficult to detect, and (3) the low frequency of anomalies leading to unbalanced data sets for training, among others. The present application addresses these issues by decoupling anomaly detection at the infrastructure layer (servers, NICs, switches, etc.) from anomaly detection at the VNF layer (L1, high-DU, CU). This enables different techniques for identifying anomalies and for reducing the monitoring overhead that is tailored to each layer.

INTENT-DRIVEN NETWORK ANALYTICS FOR PREDICTIVE NETWORK SLICE MANAGEMENT

Described are examples for providing intent based network slice management using a management data analytics function (MDAF) to predict deficiencies. A network management system receives an intent for a network slice constituent. The network management system configures computing resources for the network slice constituent to satisfy the intent based on expected performance of the computing resources. The network management system receives feedback with respect to actual performance of the network slice constituent. The network management system determines, based on analysis of the feedback by a management data analytics function (MDAF), a predicted deficiency of the network slice constituent not being able to satisfy the intent. The network management system modifies the configuration of the computing resources based on the feedback and the predicted deficiency to satisfy the intent.

SYSTEMS AND METHODS FOR IDENTIFYING AND CORRECTING ISSUES ASSOCIATED WITH A WIRELESS NETWORK

A device may receive network data identifying an SINR, an RSSI, congestion, and throughput associated with a RAN, device data identifying latency and packet loss associated with the RAN, and an issue inference confidence score associated with a machine learning model. The device may process the network data, the device data, and the issue inference confidence score, with a model, to determine one or more issues. The device may adjust TTI bundling to generate adjusted TTI bundling, may lower a QCI or a QFI and adjust associated parameters to generate QCI/QFI adjusted parameters, may adjust slice parameters to generate adjusted slice parameters, or may adjust DRX parameters to generate adjusted DRX parameters based on the one or more issues with the RAN. The device may cause the adjusted TTI bundling, the QCI/QFI adjusted parameters, the adjusted slice parameters, or the adjusted DRX parameters to be implemented by the RAN.
