Method and system for cascaded near real-time ran intelligent controllers in a mobile network

A method of servicing E2 nodes in a mobile communication network, the method comprising:

• establishing a parent cascaded near-real time radio access network intelligent controller;
• establishing network communication between the parent cascaded near-real time radio access network intelligent controller to a child cascaded near-real time radio access network intelligent controller via an E2 termination;
• servicing an E2 node through network communication to the child cascaded near-real time radio access network intelligent controller via the E2 termination;
• and
• performing an E2 node function via an E2 agent of the child cascaded near-real time radio access network intelligent controller in response to a request from the parent cascaded near-real time radio access network intelligent controller via the E2 termination.

A cascaded near-real time radio access network intelligent controller comprising:

• an E2 termination allowing communication to an E2 node and another cascaded near-real time radio access intelligent controller through the network;
• a controller executing a radio access network function for the E2 node through the E2 termination;
• and
• an E2 agent component allowing performance of an E2 function by the controller in response to requests from the another cascaded near-real time radio access network intelligent controller via the E2 termination.
