METHOD AND DEVICE FOR SUPPORTING GENERATION OF DEDICATED PDU SESSION FOR PARTICULAR USER TRAFFIC
Document Type and Number:
WIPO Patent Application WO/2021/242060
Kind Code:
A1
Abstract:
Provided are a method and a device for supporting generation of a dedicated protocol data unit (PDU) session for particular user traffic. A user equipment (UE) operating in a wireless communication system determines whether to establish a dedicated protocol data unit (PDU) session exclusively used for traffic matched to a particular traffic descriptor (TD), on the basis that a route selection descriptor (RSD) associated with the particular TD includes an indicator indicating whether to establish the dedicated PDU session. The UE requests a network to establish the dedicated PDU session on the basis of the determination of dedicated PDU session establishment.
