Flexible expert system in radio access network

A wireless communication system comprising:

• a plurality of User Equipment (UE);
• a plurality of wireless base stations configured to host Centralized Unit (CU) and Distributed Unit (DU) software;
• a rules engine;
• a first Application Programming Interface (API) wherein the rules engine is programmed with operator defined rules via the first API;
• and
• a second API coupled with the CU and DU software and configured to invoke the rules engine upon an occurrence of one or more defined events, wherein one or more of the operator defined rules is invoked via API calls to execute operator defined rules that match one or more inputs provided by at least one of the CU and DU hosted by at least one of the plurality of base stations.

An apparatus for programming operator defined rules to manage the radio resources of user equipment (UE) in a wireless communication network, the apparatus comprising:

• a memory configured to store a plurality of instructions;
• processor circuitry coupled to the memory and configured to execute the plurality of instructions to:
• receive the operator defined rules as programmable instructions;
• program a rules engine with the received instructions;
• invoke one or more of the operator defined rules via Application Programming Interface (API) calls to execute operator defined rules that match one or more inputs provided by a wireless network function;
• and
• execute actions according to the one or more defined rules that match the one or more inputs.
