Telecommunications network troubleshooting systems

Abstract:

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for telecommunications network troubleshooting. In one aspect, a method includes obtaining multiple current observations characterizing current operation of a telecommunications network, the multiple observations including performance monitoring data for the network and quality of service data for the network. One or more prior network states for the network are obtained. A current state of the network is determined, by a machine learning model, based on the current observations and the one or more prior network states. One or more actions are performed based on the current state of the network, including, when the current state of the network is an abnormal state, taking an action that is mapped to the abnormal state.
