Abstract: The present disclosure provides a method and a device by which a terminal is safely provisioned, from a PS, with credentials of an SO-SNPN to receive service when a non-public network is used in a wireless communication system. The method performed by a terminal in a wireless communication system may comprise the operations of: acquiring configuration information including a certificate of the terminal and a CA certificate associated with a certificate of a provisioning server; confirming that provisioning using a control plane is performed; generating a temporary key pair on the basis of the confirmation; and acquiring credentials of an SO-SNPN on the control plane on the basis of the configuration information and the temporary key pair.

Abstract: A method and device for applying a different security policy, per service traffic, to a protocol data unit (PDU) session in a wireless communication system. The method comprises receiving, by a session management function (SMF) managing a session for a user equipment (UE), first configuration information about a first user plane security policy of the UE from a unified data management (UDM) managing subscription information about the UE, receiving, by the SMF, second configuration information about a second user plane security policy to be applied to a specific service data flow from a policy and control function (PCF) managing a policy and charging control (PCC) rule, and determining a user plane security policy to be applied to the UE based on one selected from the first user plane security policy and the second user plane security policy according to priority.

Abstract: The disclosure relates to a 5th Generation (5G) or pre-5G communication system for supporting a higher data transfer rate than a 4th generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments of the disclosure, a method for operating an Access and Mobility Management Function (AMF) node in a wireless communication system is provided. The method includes receiving an N2 Multimedia Broadcast Service (MBS) Protocol Data Unit (PDU) session setup request message for establishing an MBS session from a Session Management Function (SMF) node, transmitting the N2 MBS PDU session setup request message to a base station, receiving an N2 MBS PDU session setup response message from the base station, and transmitting the N2 MBS PDU session setup response message to the SMF node.
