Abstract
The claimed system and method describes a root cause analysis system for a radio access network. Some aspects include automatic identification of possible causes for network issues, their ranking, determination of the root (main) cause and execution of related best actions, alerts and reporting in order to automatically identify, mitigate or eliminate the problem.
Claims20
A system for implementing a solution for a possible root cause of a cellular network failure comprising:
- a root cause analysis system for determining an optimal solution to a problem, the root cause analysis system comprising:
- an aggregator which receives and aggregates data on network anomalies from at least one self-organizing network (SON) node, wherein the aggregate data is used to determine root cause data;
- and
- a machine learning processor, which receives network status data that comprises the root cause data, analyzes the network status data to determine a possible root cause, and selects the optimal solution from a plurality of possible solutions based on past problems and previous solutions;
- a central database that stores information on the problem, the possible solutions, and the optimal solution;
- and
- a robot comprising a processor that is in communication with the central database, wherein the processor is physically configured to query the central database for the optimal solution to the problem, and wherein the robot implements the optimal solution by performing an action identified as the optimal solution.
