Communication system and method
First Claim
1. A method of authenticating a user terminal with an access node providing restricted access to a communication network, comprising:
- the user terminal transmitting a request for an authentication token to a trusted network node via an unrestricted channel on the access node, the request comprising a network identity for a user of the user terminal;
the network node verifying the identity of the user using the network identity, generating an authentication token and transmitting the authentication token to the user terminal via the unrestricted channel;
the user terminal deriving login information from the authentication token and providing the login information to the access node; and
the access node authenticating the login information and removing the restricted access such that the communication network can be accessed by the user terminal.

Abstract
A method of authenticating a user terminal with an access node providing restricted access to a communication network is provided. The method comprises the user terminal transmitting a request for an authentication token to a trusted network node via an unrestricted channel on the access node, the request comprising a network identity for a user of the user terminal. The network node verifies the identity of the user using the network identity, generates an authentication token and transmits the authentication token to the user terminal via the unrestricted channel. The user terminal derives login information from the authentication token and provides the login information to the access node. The access node authenticates the login information and removes the restricted access such that the communication network can be accessed by the user terminal.

16. An authentication system comprising:
-
a communication network; an access node arranged to provide restricted access to the communication network; a trusted network node connected to the communication network; and a user terminal arranged to transmit a request for an authentication token to the trusted network node via an unrestricted channel on the access node, the request comprising a network identity for a user of the user terminal, wherein the network node is arranged to verify the identity of the user using the network identity, generate an authentication token and transmit the authentication token to the user terminal via the unrestricted channel, the user terminal is arranged to derive login information from the authentication token and providing the login information to the access node, and the access node is arranged to authenticate the login information and remove the restricted access such that the communication network can be accessed by the user terminal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
