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.
Claims13
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 unified data management (UDM) node or an access and mobility management function (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 a relay User Equipment (UE) to perform authentication, comprising:
- receiving a direct communication request message from the Remote a remote UE;
- transmitting a Remote UE report message to a Session Management Function (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.
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 a remote UE;
- transmitting a Remote UE report message to a Session Management Function (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 remote UE.
