Method and device for providing split computing service in wireless communications system

A session management function (SMF) in a wireless communication system supporting split computing, the SMF comprising:

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• receive, via a first network entity from an application server, quality of service (QoS) related information to be applied to a user equipment (UE) for the split computing, the first network entity being either a policy control function (PCF) or a user data management (UDM), and
• transmit, to the UE via a network, the QoS related information for the split computing in a session establishment procedure for the UE.

A user equipment (UE) in a wireless communication system supporting split computing, the UE comprising:

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• transmit, to a session management function (SMF) via a network, a protocol data unit (PDU) session establishment request message including a PDU session ID, and
• receive, via the network from the SMF, a PDU session establishment response message including quality of service (QoS) related information to be applied to the UE for the split computing.
