Method and device for supporting uplink scheduling in consideration of transmission delay of tethered device

A method of an access and mobility management function (AMF) entity supporting uplink scheduling of a terminal using a tethered device, the method comprising:

• transmitting, to a session management function (SMF) entity, a protocol data unit (PDU) session-related session management (SM) message including at least one of a tethered device support indication and tethered device jitter information;
• in response to the PDU session-related SM message, receiving, from the SMF entity, N2 SM information including at least one of the tethered device support indication and the tethered device jitter information;
• and
• transmitting, to an access network (AN), the N2 SM information.

A session management function (SMF) entity supporting uplink scheduling of a terminal using a tethered device, the SMF entity comprising:

• a transceiver;
• and
• least one processor coupled to the transceiver and configured to:
• receive, from an access d ty management function entity, a protocol data unit (PDU) session-related session management (SM) message including at least one of a tethered device support indication and tethered device jitter information, and
• in response to the PDU session-related SM message, transmit, to an access network (AN) via the AMF entity, N2 SM information including at least one of the tethered device support indication and the tethered device jitter information.
