Method and apparatus for ue authentication for remote provisioning

A method for operating a provisioning server (PVS) in a wireless network, the method comprising:

• configuring a restricted packet data unit (PDU) session with a terminal;
• receiving a remote provisioning request message including a subscription permanent identifier (SUPI) from the terminal;
• and
• transmitting a remote provisioning response message to the terminal in response to the remote provisioning request message,
• wherein the remote provisioning response message includes standalone non-public network (SNPN) credentials and subscription data of the terminal in case that remote provisioning for the terminal is approved.

A method for operating a default credentials server (DCS) in a wireless network, the method comprising:

• performing mutual authentication with a provisioning server (PVS);
• receiving an authentication request message including a subscription permanent identifier (SUPI) from the PVS;
• and
• transmitting an authentication response message including an authentication result to the PVS in response to the authentication request message,
• wherein the authentication request message is transmitted based on a remote provisioning request message received from a terminal, and the authentication response message includes standalone non-public network (SNPN) credentials and subscription data of the terminal in case that the authentication result indicates authentication success.
