1. A method performed by a session management function (SMF) entity in a mobile communication system, the method comprising:
receiving, from a policy control function (PCF) entity, an application function (AF) influenced traffic steering enforcement control information including data path latency requirement information, wherein the data path latency requirement information comprises a maximum allowed user plane latency; and
performing a protocol data unit (PDU) session anchor-user plane function (PSA-UPF) relocation with a PSA-UPF entity, wherein the PSA-UPF entity has a minimum user plane latency among at least one PSA-UPF entity satisfying the maximum allowed user plane latency.
