E2 service model abstraction

A method, comprising:

• receiving, by a near real-time radio access network intelligent controller of a system comprising at least one processor, respective indications of supported service models and key performance indicators from respective network nodes of a group of network nodes in a radio access network;
• receiving, by the by the near real-time radio access network intelligent controller, a request from an application of the near real-time radio access network intelligent controller for a key performance indicator;
• subscribing, by the near real-time radio access network intelligent controller, to a network node of the group of network nodes for the key performance indicator, wherein the network node supports a service model that is unsupported by the application and that is supported by the near real-time radio access network intelligent controller;
• and
• returning, by the near real-time radio access network intelligent controller, the key performance indicator to the application.

A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a near real-time radio access network intelligent controller of a system comprising at least one processor to perform operations, comprising:

• receiving respective indications of supported service models and key performance indicators from respective network nodes of a group of network nodes;
• receiving a request from an application of the near real-time radio access network intelligent controller for a key performance indicator;
• subscribing to a network node of the group of network nodes for the key performance indicator;
• and
• returning the key performance indicator to the application.
