Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided is a method of solving a problem in which PDU session creation is rejected due to an NSAC in a wireless communication system according to an embodiment of the disclosure through alternative S-NSSAI.
Claims12
A method performed by a terminal in a wireless communication system, the method comprising:
- transmitting, to an access and mobility management function (AMF), a message for requesting an establishment of a protocol data unit (PDU) session associated with a network slice;
- and
- performing the establishment of the PDU session with a session management function (SMF),
- wherein in case that the network slice is to be replaced with an alternative network slice, information on the alternative network slice is received from the SMF, and
- wherein the alternative network slice is selected from at least one allowed network slice.

A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, to an access and mobility management function (AMF) via the transceiver, a message for requesting an establishment of a protocol data unit (PDU) session associated with a network slice, and
- perform the establishment of the PDU session with a session management function (SMF)
- wherein in case that the network slice is to be replaced with an alternative network slice, information on the alternative network slice is received from the SMF, and
- wherein the alternative network slice is selected from at least one allowed network slice.
