Method and device for mapping UE routing selection policy in wireless communication system

Abstract

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates, and pertains to an operation method of a user equipment (UE). The operation method comprises the steps of transmitting a registration request message including a traffic category support indication to an access and mobility management function (AMF) via an access node, receiving, from the AMF via the access node, a UE configuration update message including UE route selection policy (URSP) rules determined on the basis of the traffic category support indication and first traffic category mapping information, and determining a protocol data unit (PDU) session for application traffic on the basis of the URSP rules and pre-stored second traffic category mapping information.
