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.

Abstract: A scalable virtualized network core is provided to allow for incrementally adjusting network resources in response to changing demand, and for improved flexibility in network management and control. The scalable virtualized network core provides a cloud evolved packet core that has virtual machines performing the functions of the individual server elements. As demand for network resources changes, additional virtual machines can be brought online or virtual machines can be terminated to efficiently address the demand. An abstraction agent can be provided to facilitate the physical to logical connections so that to the perspective of elements in a radio access network, no changes have been made. The abstraction agent also facilitates network control and management of the virtual machines.

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: The described technology is generally directed towards cellular communication network sleep management. A central network automation platform can control sleep settings deployed to radio access network nodes that support the cells of the cellular communication network. The network automation platform can collect cell configuration data and can use the cell configuration data to determine sleep settings for sleep-eligible cells. The network automation platform can furthermore monitor performance of the sleep-eligible cells and neighbor cells to determine whether the sleep settings have led to degraded performance.

Abstract: The disclosed technology is directed towards automated configuration enforcement in wireless communication systems, which can be implemented in an audit manager (e.g. an ONAP micro-service) as part of an overall architecture. The audit manager obtains misconfiguration data representing misconfigured configurable parameter data of network elements of a radio access network, and corrective parameter data corresponding to the misconfiguration data. The audit manager issues a reconfiguration action to the network elements, which instructs the network elements to reconfigure their current configurable parameter data based on the corrective parameter data. Following reconfiguration, the audit manager operates to monitor the network elements performance, e.g., to check for performance degradation of a cell site relative to previous performance metrics.
