Summary:An enhanced session establishment procedure is proposed for MTU parameter handling under intersystem change between 5GS and EPS. A PDU session of "Ethernet" or "Unstructured" PDU session type can be transferred to a PDN connection of "non-IP" PDN type, thus the UE can request the non-IP link MTU parameter in the PDU session establishment procedure. A PDN connection of "non-IP" PDN type can be transferred to a PDU session of "Unstructured" PDU session type, thus the UE can request the Unstructured link MTU parameter in the default EPS bearer context activation procedure.
