Methods and systems for intelligent roaming using radio access network intelligent controllers

An open radio access network (“O-RAN”) of a home network that performs intelligent roaming of user equipment (“UE”) of the home network to a visited network, the O-RAN comprising:

• a near-real-time radio access network intelligence controller (“near-RT RIC”) that receives performance reports of each UE in coverage areas of border cell sites of the visited network from a near-RT RIC executing in the visited network;
• a non-real-time radio access network intelligence controller (“non-RT RIC”) that receives performance reports of each UE in coverage areas of edge cell sites of the home network, performance reports of each UE in the coverage areas of border cell sites, home network analytic results from a home network data analytics function executing in the mobile core of the home, and visited network analytic results from a visited network data analytics function executing in the mobile core of the visited network;
• and
• an rApp that pushes UEs, in the coverage areas of the edge cell sites, to roam on the visited network based on the edge performance reports of the home and the visited network, the home network analytic results, and the visited network analytic results.
