Network Intelligence-as-a-Service in A.I.-Native Telecommunication Systems
A system and method for modelling, generating intelligence of and optimization of interdependent network entities in a wireless telecom network with a computer using machine learning that includes receiving network entity-specific data relating to a network function and imputing missing values in the received network entity-specific data. Groups of interdependent network entities are associated with each other to generate aggregated data to determine an impact each interdependent network entity has on the group and for predicting Key Performance Indicators (KPIs) of the interdependent network entities based on the aggregated data. From this information, optimizations to improve the KPIs are generated and tested, where control actions are implemented based on the outcome of the tested optimizations.
