Abstract

A method for handling a collision of a UE-requested PDU session establishment procedure and a network-requested PDU session modification procedure is proposed. When a PDU SESSION ESTABLISHMENT REQUEST message indicates that the UE-requested PDU session establishment request procedure is to handover an existing PDU session between 5G 3GPP access and 5G non-3GPP access, UE and NW proceed with the UE-requested PDU session establishment procedure and abort the NW-requested PDU session modification procedure. When a PDU SESSION ESTABLISHMENT REQUEST message indicates that the UE-requested PDU session establishment request procedure is to establish user plane resources for an MA PDU session, UE and NW proceed with both the UE-requested PDU session establishment procedure and the NW-requested PDU session modification procedure.
