METHOD FOR AUTHENTICATION OF A MOBILE NODE TO A WIRELESS ACCESS NETWORK

摘要

Method for authentication and/or authorization of a mobile node to a wireless access network, whereby the mobile node, the air interface and the wireless access network comprise a service network for providing services to a user of the mobile node, to provide an authentication and authorization mechanism for temporary subscriptions, which is reliable and easy to implement, and which takes into account current user location, i.e. mobility, whereby a self-­authenticating token for temporary subscription is generated by a code generation server external to the service network, authentication/authorization information is derived from the token by the mobile node, and the mobile node utilizes the authentication/authorization information to authenticate and/or authorize itself to an authentication/authorization server located in the service network.
