Document Type and Number:
WIPO Patent Application WO/2018/174383
Kind Code:
A1
Abstract:
One disclosure in the present specification provides a session management method performed by a session management function (SMF) node. The session management method may comprise: a step of transmitting, to a user plane function (UPF) node, a request message for discarding traffic buffering, when a notification of the detection of particular traffic associated with a wireless device has been received, and if additional authentication is required for the particular traffic; and a step of transmitting a message for triggering the wireless device to establish a new packet data unit (PDU) session, to an access and mobility management function (AMF) node.
