1. A method for establishing a connection between a distributed unit (DU) of a network node and a central unit (CU) of the network node, under a service level agreement (SLA) therebetween, the method performed by the DU and comprising:
determining a cell to serve;
sending, by the DU, a message to a radio control function (RCF) of the CU, the message including an identity of the DU and at least a request for the determined cell to serve;
in response to the message, receiving, at the DU from the RCF, an identity of the CU and a cell identity corresponding to the determined cell; and
establishing the connection between the DU and CU based at least on the identity of the DU, the identity of the CU and the identity of the determined cell.
