Title:
DEVICE AND METHOD FOR MANAGING SESSION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/204518
Kind Code:
A1
Abstract:
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transfer rate beyond a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments, a device of user equipment (UE) in a wireless communication system may comprise at least one transceiver and at least one processor operably connected to the at least one transceiver, wherein the at least one processor is configured to: perform data communication on the basis of a first protocol data unit (PDU) session through a first access network; transmit a PDU session establishment request message for generating a second PDU session, to the network entity of a session management function (SMF) through a second access network; receive a PDU session establishment accept message from the network entity of the SMF; and perform data communication on the basis of the first PDU session and the second PDU session according to the PDU session establishment accept message, wherein the first access network comprises one of 3rd generation partnership project (3GPP) access and non-3GPP access, and the second access network comprises the remaining one of the 3GPP access and non-3GPP access.
