1. A method performed by a core network entity, the method comprising:
receiving, from a master node (MN), a session modification message for offloading at least one quality of service (QoS) flow of a protocol data unit (PDU) session from the MN to a secondary node (SN), wherein the PDU session comprises a plurality of QoS flows of the PDU session; and
transmitting, to the MN, a response message,
wherein the session modification message includes information of the at least one QoS flow,
wherein the MN is configured with a first layer for mapping between a QoS flow and a data radio bearer (DRB),
wherein the SN is configured with a second layer for mapping between a QoS flow and a DRB, and
wherein the first layer and the second layer are configured for the PDU session for the offloading of the at least one QoS flow of the PDU session between the MN and the SN.
