Abstract
In conventional public networks, a subscriber identity module (SIM) is installed on a mobile station for authenticating users and improving the communication security between mobile stations and the network. This specification proposes an authentication agent (AA) installed on a network and with the SIM of the mobile station installed on the AA. Thus, the mobile station gets authenticated from the AA and then the AA uses the SIM of the mobile station to obtain authentication from the authentication server.
