1. A method, comprising:
establishing a multi-access protocol data unit (MA PDU) session by a user equipment (UE), wherein the UE is registered to a Public Land Mobile Network (PLMN) over both a first access type and a second access type;
transmitting a PDU session establishment request message over the first access type;
receiving a PDU session establishment accept message, wherein the UE considers the MA PDU session is activated and considers the user plane resources are established on the first access based on the PDU session establishment accept message, and wherein the UE starts PDU data transmission over the first access type upon receiving the PDU session establishment accept message; and
starting a timer upon receiving the PDU session establishment accept message, wherein the UE re-initiates a UE-requested PDU session establishment procedure over the second access type when the UE has not received a notification for the second access type upon timer expiry.
