Automated detection and mitigation of intra- and interdomain conflicts in open radio access networks

A system comprising:

• a non-real-time radio access network intelligent controller (non-RT RIC) of a radio access network (RAN);
• and
• a plurality of near-real-time RAN intelligent controllers (near-RT RICs) of the RAN, the non-RT RIC controls one or more operations of the near-RT RICs;
• wherein:
• the non-RT RIC generates a policy for a near-RT RIC from the plurality of near-RT RICs by analyzing an activity log of a plurality of xApps being executed by the near-RT RIC;
• in response to receiving a request from an xApp from the plurality of xApps to update a parameter of the RAN:
• the near-RT RIC updates the parameter based on the policy allowing the xApp to update the parameter;
• and
• the near-RT RIC maintains the parameter unchanged based on the policy restricting the xApp from updating the parameter.

A computer program product comprising a memory device with computer-executable instructions therein, the computer-executable instructions when executed by a processing unit perform a method comprising:

• generating, by a non-Real-Time RAN Intelligent Controller (non-RT RIC) of a radio access network (RAN), a policy for a near-Real-Time RAN Intelligent Controller (near-RT RIC) by analyzing an activity log of a plurality of xApps, which are being executed by the near-RT RIC;
• and
• sending, by the non-RT RIC the policy to the near-RT RIC to cause the near-RT RIC, in response to receiving a request from an xApp from the plurality of xApps to update a parameter of the RAN:
• update the parameter based on the policy allowing the xApp to update the parameter;
• and
• maintain the parameter unchanged based on the policy restricting the xApp to update the parameter.
