Abstract: Various embodiments disclosed herein provide for a tower outage impact predictor that can determine the service impact on an end user during a cellular tower outage. Radio signal profiling divides an area into grids, and then constructs a radio signal profile for each grid based on user equipment (UE) measurement data for each grid. The number of UEs in each grid is then determined, and then the number of UEs that lose service for a simulated cellular tower outage is determined. Based on the impact analysis, a more resilient backhaul network can be implemented by determining backhaul rehoming changes that optimally home cellular towers to various backhaul network devices.

Abstract: Methods, systems, and products infer performance of a domain name system. Queries to, and responses from, the domain name system are logged and categorized. Each category is associated with a different performance issue related to the domain name system. The number of entries in each category may be used to infer the performance of the domain name system.

Abstract: To efficiently mitigate cell coverage disruptions caused by either unplanned equipment failures or planned outages during maintenance activities, an efficient cell site outage mitigation system is provided to calculate an optimal configuration for neighboring cell site devices before adjusting the cell site configuration settings to cover the coverage gap. The optimal configuration is determined using an offline model learner. Radio frequency propagation models and user demand and distribution models can be used to determine the offline solution. The optimal configuration setting learnt using an offline model is then implemented when an outage is determined to have occurred in the operational field.

Abstract: Example methods disclosed herein to localize anomalies in a communication network include identifying a first set of abnormal nodes in the communication network, and including respective ones of the first set of abnormal nodes having a number of normal direct descendent nodes that is less than a combined number of abnormal direct descendent nodes and indeterminate direct descendent nodes in a set of candidate nodes. Such disclosed example methods also include iteratively selecting ones of the set of candidate nodes to include in a set of root cause abnormal nodes representing sources of the anomalies in the communication network. In such disclosed example methods, the ones of the set of candidate nodes are selected based on sizes of respective subsets of the abnormal nodes from the first set of abnormal nodes covered by the candidate nodes.

Abstract: A processing system may apply a data set comprising utilization metrics of a cells of a cell sector to a throughput prediction model to obtain a first predicted throughput for the cell sector for a designated future time period and for all cells being in an active state. The processing system may generate a first modified data set simulating a first cell being placed in an inactive state, by distributing utilization metrics of the first cell over at least one additional cell, and may apply the first modified data set to the throughput prediction model to obtain a second predicted throughput. The processing system may then determine that the second predicted throughput meets a threshold throughput that is based on the first predicted throughput, and transmit at least one instruction to place the first cell in the inactive state for the designated future time period in response to the determining.
