Abstract
The present disclosure provides a User Equipment (UE) comprising a transceiver circuit; and a controller configured to control the transceiver circuit to send, to an Access and mobility Management Function (AMF) of a communication node, an identifier, wherein upon successful authentication of a network access function of the UE in the communication node, the controller is configured to maintain a secure connection with the communication node.
Claims10
A first network node comprising:
- at least one memory storing instructions, and
- at least one processor configured to execute the instructions to:
- receive an authorization request message including a Subscription Concealed Identifier (SUCI) from a second network node;
- convert the SUCI to a Subscription Unique Permanent Identifier (SUPI);
- and
- send, to the second network node, an authentication message including the SUPI and information for performing subscriber authentication for Non-Public Network (NPN).
A first network node comprising:
- at least one memory storing instructions, and
- at least one processor configured to execute the instructions to:
- send an authorization request message including a Subscription Concealed Identifier (SUCI) to a second network node;
- and
- receive, from the second network node, an authentication message including a Subscription Unique Permanent Identifier (SUPI) converted from the SUCI and information for performing subscriber authentication for Non-Public Network (NPN).
A method performed by a first network node comprising:
- receiving an authorization request message including a Subscription Concealed Identifier (SUCI) from a second network node;
- converting the SUCI to a Subscription Unique Permanent Identifier (SUPI);
- and
- sending an authentication message including the SUPI and information for performing subscriber authentication for Non-Public Network (NPN), to the second network node.
A method performed by a first network node comprising:
- sending an authorization request message including a Subscription Concealed Identifier (SUCI) to a first network node;
- and
- receiving, from the first network node, an authentication message including a Subscription Unique Permanent Identifier (SUPI) converted from the SUCI and information for performing subscriber authentication for Non-Public Network (NPN).
A non-transitory computer readable medium having stored thereon a program that causes a computer to execute:
- receiving an authorization request message including a Subscription Concealed Identifier (SUCI) from a network node;
- converting the SUCI to a Subscription Unique Permanent Identifier (SUPI);
- and
- sending, to the network node, an authentication message including the SUPI and information for performing subscriber authentication for Non-Public Network (NPN).
A non-transitory computer readable medium having stored thereon a program that causes a computer to execute:
- sending an authorization request message including a Subscription Concealed Identifier (SUCI) to a network node;
- and
- receiving, from the network node, an authentication message including a Subscription Unique Permanent Identifier (SUPI) converted from the SUCI and information for performing subscriber authentication for Non-Public Network (NPN).
