Autenticeringssystem och -förfarande

摘要

The method is for authentication in a communication network. A mobile station and an authentication server give access to services in the network. A user of a mobile station first sends a request for a service or a password in a message from the mobile station. The authentication server controls the location information for the mobile station, and sends a password to the mobile station or grants access to the user as a reply to the request if the location information is accepted by the server.
