Abstract
The present invention discloses a method and apparatus for identifying handover requirement by a Radio access network (RAN) controller in open RAN (O-RAN) environment. The O-RAN environment has a virtualized network architecture having at least one RAN controller that is able to control, via an E2 node, a plurality of user equipments (UEs) positioned in a serving cell, a cell covering a location for serving a UE, the serving cell is adjacent to a plurality of neighbour cells. The method includes parallel execution of the operations performed by the RAN controller for each serving cell and each of the neighbor cell and updating CIOs in stepwise i.e., gradually with repeated comparing of the serving cell load parameter with each of the plurality of neighbour cell load parameters and updating the serving cell handover parameter and the plurality of neighbour cell handover parameters based on the comparison.
