Abstract
One disclosure of the present specification provides a method for an SMF node to perform authentication. The method may include the steps of: receiving, from a relay UE, a Remote UE report message related to a Remote UE connected to the relay UE; transmitting a request message to a UDM node or an AMF node on the basis of the Remote UE report message including an SUCI of the remote unit; receiving a response message, including an SUPI of the Remote UE, from the UDM node or the AMF node; and transmitting an authentication request message, requesting authentication for the Remote UE, to an authentication server.
Claims15
A method for a Session Management Function (SMF) node to perform authentication, comprising:
- receiving a Remote User Equipment (UE) report message related to a Remote UE connected to a relay UE from the Relay UE;
- transmitting a request message to a UDM node or an AMF node, based on that the Remote UE report message includes a Subscription Concealed Identifier (SUCI) of the Remote UE;
- receiving, from the UDM node or the AMF node, a response message including a Subscription Permanent Identifier (SUPI) of the Remote UE, in response to the request message;
- and
- transmitting an authentication request message requesting authentication for the Remote UE to an authentication server, based on that the Remote UE report message is received,
- wherein the authentication request message includes a SUPI of the Remote UE.
A method for Relay UE to perform authentication,
- receiving a direct communication request message from the Remote UE;
- transmitting a Remote UE report message to the SMF node, based on the direct communication request message being received;
- and
- receiving a message including an authentication result for the Remote UE from the SMF node,
- wherein the direct communication request message includes Remote UE ID information of the Remote UE,
- wherein the Remote UE ID information includes a Subscription Concealed Identifier (SUCI) of the Remote UE,
- wherein the SUCI of the Remote UE is used by the SMF node to obtain a Subscription Permanent Identifier (SUPI) of the Remote UE.
(canceled)
A Relay User Equipment (UE) that performs authentication, the Relay UE comprising:
- at least one processor;
- and
- at least one memory storing instructions and operably electrically connectable with the at least one processor,
- wherein the operations performed based on the execution of the instructions by the at least one processor include:
- receiving a direct communication request message from the Remote UE;
- transmitting a Remote UE report message to the SMF node, based on the direct communication request message being received;
- and
- receiving a message including an authentication result for the Remote UE from the SMF node,
- wherein the direct communication request message includes Remote UE ID information of the Remote UE,
- wherein the Remote UE ID information includes a Subscription Concealed Identifier (SUCI) of the Remote UE,
- wherein the SUCI of the Remote UE is used by the SMF node to obtain a Subscription Permanent Identifier (SUPI) of the Remote UE.
