1. A method performed by a visited session management function (V-SMF) supporting an edge computing service for a roaming user equipment (UE) in a wireless communication system, the method comprising:
receiving a first request message for protocol data unit (PDU) session establishment of the roaming UE from an access and mobility management function (AMF), wherein the first request message includes:
a first indication indicating that session breakout (SBO) of a home routed (HR) roaming session in a visited network is supportable, and
a session management policy indication for supporting the edge computing service through HR roaming;
selecting a visited policy control function (V-PCF) providing an SBO policy for supporting the edge computing service for the HR roaming session according to the first request message; and
transmitting a second request message requesting the edge computing service through the HR roaming session to the V-PCF, wherein the second request message includes an indication requesting an SBO policy for the HR roaming session.
