Abstract
The one disclosure of the present specification proposes a method for managing session. The method may be performed by a session management function, SMF, node and comprise: generating a packet data unit, PDU, session for a user equipment, UE; receiving, from an access and mobility management function, AMF, node, information about the UE; and determining, based on the information, whether to transmit an indication for notifying a user plane function, UPF, node to discard a downlink data for the PDU session of the UE. The determination may be dependent on whether the PDU session corresponds to a first service provided to the UE.

A method for operating a session management function (SMF) node in a wireless communications network that includes an access and mobility management function (AMF) node, the method performed by the SMF node and comprising:
- while a packet data unit (PDU) session for a user equipment (UE) is established in the SMF node, receiving, from the AMF node, information about a location change of the UE out of a first local area data network (LADN) of the established PDU session;
- and
- discarding data associated with the established PDU session while maintaining the established PDU session.
A device operating as a session management function (SMF) node in a wireless communications network that includes an access and mobility management function (AMF) node, the device comprising:
- a memory;
- a transceiver;
- and
- a processor operatively connected to the transceiver and the memory, the transceiver configured for:
- while a packet data unit (PDU) session for a user equipment (UE) is established in the SMF node, receiving, from the AMF node, information about a location change of the UE out of a first local area data network (LADN) of the established PDU session;
- and
- discarding data associated with the established PDU session while maintaining the established PDU session.
