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.
Claims19
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.
A communication system comprising:
- a user equipment (UE);
- a first node;
- a second node;
- and
- a third node,
- wherein the first node is configured to:
- receive a registration request message transmitted by the UE,
- verify information indicating whether the UE has a subscription for specific service by decrypting the registration request message including the information and a first identifier, and
- send, to the second node, an authentication request message including a second identifier upon successful verification of the information,
- wherein the second node is configured to:
- verify the second identifier, and
- route, to the third node, the authentication request based on a third identifier included in the first identifier, and
- wherein the third node is configured to:
- decrypt the authentication request message, and
- transmit a response for providing the secure connection with the UE.
A method for establishing a secure connection between a user equipment (UE) and a network, the method comprising:
- sending, from the UE to a first node of the network, a registration request including information indicating whether the UE has a subscription for specific service,
- wherein the registration request includes a first identifier, and the first identifier includes the information;
- verifying, by the first node of the network, the registration request;
- sending an authentication request to a second node of the network upon successful verification of the information based on a second identifier which is included in the first identifier,
- wherein the second identifier routes nodes of the network for the specific service, and the authentication request includes the first identifier, UE network access capability and a third identifier, wherein the third identifier identifies a specific serving network;
- verifying, by the second node of the network, the third identifier;
- sending, by the second node of the network, upon successful verification of the third identifier, an authentication data request to a third node of the network based on the second identifier;
- de-concealing the first identifier, by the third node of the network, to verify UE network access restriction information;
- and
- sending, by the third node of the network, upon successful verification of the de-concealed first identifier and the information, an authentication data feedback to the second node of the network including the first identifier and authentication vector for the specific service.
