Data Sharing Between a Non-RT-RIC and a NEARRT-RIC for Radio Resource Management

According to some embodiments, a method performed by a non-real time radio access network intelligent controller (NonRT-RIC) network node comprises obtaining data for improving radio resource management (RRM) of a radio access network (RAN) and building an A1 interface message comprising one or more enrichment information (EI) elements based on the obtained data. Each of the one or more EI elements comprises an identifier of one or more wireless devices, a type indicator indicating a type of enrichment data included in the EI element, and the enrichment data. The method further comprises transmitting the AI interface message to a near real time radio access network intelligent controller (NearRT-RIC).
