processing circuitry; and

a memory coupled to the processing circuitry, the memory storing instructions, when executed, to cause the processing circuitry to:

display a plurality of policies for an interface service of the RAN organized by a plurality of RAN interface policy types, wherein the interface service is an interface service for one of an AI interface, an O1 interface, or an O2 interface;

receive an indication of selection of a conflict resolution strategy for a selected RAN interface policy type of the plurality of RAN interface policy types;

determine whether the interface service of the RAN has a conflict based on the selected conflict resolution strategy for the selected RAN interface policy type;

when the interface service has the conflict and the selected conflict resolution strategy is priority-based overriding, display respective priorities for policy conflict management of a plurality of applications and an indication of at least one of the plurality of applications causing the conflict; and

based on the selected conflict resolution strategy for the selected RAN interface policy type, modify a configuration of the RAN.

2 . The RIC of claim 1 , further comprising:

when the interface service has the conflict, do not accept the selected conflict resolution strategy for the selected RAN interface policy type.

3 . The RIC of claim 1 , wherein the indication of the selection of the conflict resolution strategy is received from a user by a user interface of the RIC.

4 . The RIC of claim 1 , wherein the selected conflict resolution strategy comprises one of allow, first come first served, or priority-based overriding.

5 . The RIC of claim 1 , wherein when the selected conflict resolution strategy is priority-based overriding, the instructions, when executed, further cause the processing circuitry to receive a new priority for at least one of the plurality of applications.

6 . The RIC of claim 1 , wherein the selected RAN interface policy type is associated with a conflict resolution strategy.

7 . The RIC of claim 6 , wherein the selected RAN interface policy type comprises an AI policy type and the selected RAN interface policy type is associated with an A1 type definition.

8 . The RIC of claim 1 , wherein the RAN comprises at least one interface including at least one of the A1 interface, the O1 interface, the O2 interface, or an R1 interface of the RIC.

9 . The RIC of claim 1 , wherein, to determine whether the interface service has the conflict, the instructions further cause the processing circuitry to:

determine, based on a comparison of a first policy of an application with a second policy of one of an application and a different application, whether one or more statements of the first policy contradict one or more statements of the second policy.

10 . The RIC of claim 1 , wherein, to determine whether the interface service has the conflict, the instructions further cause the processing circuitry to:

determine, based on a comparison of a first policy of an application with a second policy of the application or a different application, whether one or more statements of the first policy overlap in scope with one or more statements of the second policy.

11 . The RIC of claim 1 , wherein, to determine whether the interface service has the conflict, the instructions further cause the processing circuitry to:

determine whether one or more statements within a policy of an application exceeds a limit of a target of the policy.

12 . The RIC of claim 11 , wherein the policy comprises a first policy, and wherein the instructions further cause the processing circuitry to:

receive, from a second application, a request for conflict guidance for an implementation of a second policy;

determine whether the second policy has the conflict; and

provide a guidance response to the application based on the determination whether the second policy has the conflict.

13 . The RIC of claim 12 , wherein the guidance response comprises one or more of:

the indication of the conflict and whether the second policy creates the conflict;

one or more recommendations to resolve the conflict; and

the conflict information identifying a cause of the conflict.

14 . The RIC of claim 1 , wherein to determine whether the interface service has the conflict, the instructions further cause the processing circuitry to determine whether the interface service has at least one of a direct conflict, an indirect conflict, or an implicit conflict.

15 . A method comprising:

displaying a plurality of policies for an interface service of a radio access network (RAN) organized by a plurality of RAN interface policy types, wherein the interface service is an interface service for one of an AI interface, an O1 interface, or an O2 interface;

receiving an indication of selection of a conflict resolution strategy for a selected RAN interface policy type of the plurality of RAN interface policy types;

determining whether the interface service of the RAN has a conflict based on the selected conflict resolution strategy for the selected RAN interface policy type;

when the interface service has the conflict and the selected conflict resolution strategy is priority-based overriding, displaying respective priorities of a plurality of applications for policy conflict management and an indication of at least one of the plurality of applications causing the conflict; and

based on the selected conflict resolution strategy for the selected RAN interface policy type, modifying a configuration of the RAN.

16 . The method of claim 15 , further comprising:

when the interface service has the conflict, do not accept the selected conflict resolution strategy for the selected RAN interface policy type.

17 . The method of claim 15 , wherein the indication of the selection of the conflict resolution strategy is received from a user by a user interface of a non-real-time (RT) Radio Access Network Intelligent Controller (RIC).

18 . A non-transitory computer-readable storage media comprising instructions that, when executed, cause one or more processors of a Radio Access Network Intelligent Controller (RIC) for managing non-real time events of a radio access network (RAN) to: display a plurality of policies for an interface service of the RAN organized by a plurality of RAN interface policy types, wherein the interface service is an interface service for one of an AI interface, an 01 interface, or an 02 interface; receive an indication of selection of a conflict resolution strategy for a selected RAN interface policy type of the plurality of RAN interface policy types; determine whether the interface service of the RAN has a conflict based on the selected conflict resolution strategy for the selected RAN interface policy type; when the interface service has the conflict and the selected conflict resolution strategy is priority-based overriding, display respective priorities of a plurality of applications for policy conflict management and an indication of at least one of the plurality of applications causing the conflict; and based on the selected conflict resolution strategy for the selected RAN interface policy type, modify a configuration of the RAN.

19 . The non-transitory computer-readable storage media of claim 18 , wherein the selected RAN interface policy type is associated with a conflict resolution strategy.
