Systems and methods for inter radio intelligent controller communication

A system for inter radio intelligent controller communication in an open Radio Access Network (O-RAN), the system comprising:

• a network device communicatively coupled to a Near-Real Time Radio Intelligent Controller (Near-RT RIC);
• wherein the network device is further operatively coupled to a plurality of cells in a heterogenous network, the plurality of cells further communicatively coupled to the open radio access network unit (O-RAN), wherein said network device further comprises a processor and a memory, the memory comprises processor-executable instructions corresponding to one or more xAPPs associated with the Near-RT RIC, which on execution, cause the network device to:
• receive, a first set of instructions to split the Near-RT RIC into a plurality of Near-RT RIC modules;
• create a logical interface among the plurality of Near-RT RIC modules;
• and establish a communication pathway among the plurality of Near-RT RIC modules through the logical interface, wherein the communication pathway comprises:
• initiate, by a first Near-RT RIC module, a setup procedure to establish an iNear-RT RIC interface link with a second Near-RT RIC module that is associated with the new neighbour cell's RIC, at the reception of the new neighbour cell's RIC transport layer address;
• send, by the first Near-RT RIC module, a Near-RT RIC setup request message (INear-RT RIC) to the second Near-RT RIC module with a list of supported cells associated with the new neighbour cell;
• acknowledge, by the second Near-RT RIC module, the Near-RT RIC setup request message (iNear-RT RIC);
• update, by the second Near-RT RIC module, the list of supported cells with a received list of cells from the network device;
• respond back, by the first Near-RT RIC module by sending a Near-RT RIC setup response message with the list of supported cells;
• and update, by the first Near-RT RIC module, the list of supported cells with the received list of cells to successfully establish between the link between the first Near-RT RIC module and the second Near-RT RIC module.
