1. A method, performed by a distributed unit (DU) for a radio access network (RAN) node in a 5G communication network defining one or more cells, of signaling public warning system (PWS) success indication, the method comprising:
receiving, from a central unit (CU) via an F1 interface with the DU, a write-replace warning message to trigger warning alert delivery by broadcasting, from a radio unit (RU) via an air interface, a system information block (SIB) including a warning message;
generating a PWS success indication message for the CU to inform the CU regarding successful delivery of the warning message over the air interface; and
in response to the RU completing broadcasting of the SIB successfully across the one or more cells, triggering delivery to the CU of the PWS success indication message over the F1 interface.
