Traffic management to reduce cellular network outages

Abstract

A traffic orchestrator reduced cellular network outages via improved traffic management. The orchestrator receives network management logs and call logs from network nodes and uses them, along with key performance indicators (KPIs) for network nodes, traffic patterns, and network topology, to identify nodes that are operating in a degraded manner, or are not fit for traffic. The orchestrator generates and distributes traffic advisories to various network nodes. This rebalances traffic to reduce losses to traffic throughput, such as by rerouting traffic around degraded nodes and nodes that are not fit for traffic. This proactive approach occurs prior to a network node being reported as unavailable to a network repository (e.g., a 5G NRF), and not only enables some of the degraded nodes an opportunity to recover prior to an outage (reducing outages), but also reroutes traffic prior to impending outages, reducing the effect on users when outages.
