1. A method comprising:
transmitting a first PDU session establishment request message for establishment of a PDU session associated with non-3rd Generation Partnership Project (3GPP) access or 3GPP access,
wherein the first PDU session establishment request message includes first report information related to 3GPP Packet Switch (PS) Data Off status of a User Equipment (UE),
wherein the first report information is included in the first PDU session establishment request, regardless of whether the PDU session is associated with the 3GPP access or the non-3GPP access,
wherein the 3GPP PS Data Off status for the first PDU session does not affect data transfer over the non-3GPP access,
wherein the 3GPP PS Data Off prevents traffic via the 3GPP access except for traffic related to 3GPP PS Data Off Exempt services, when the 3GPP PS Data Off is activated; and
transmitting a second PDU session establishment request message for handover of the PDU session between the 3GPP access and the non-3GPP access,
wherein the second PDU session establishment request message is not needed to include a second report information related to the 3GPP PS Data Off status, based on that the 3GPP PS Data Off status of the UE is not changed since a last report information.
