Abstract: A mobile terminal (MT) sets up a wireless ATM radio communication connection (WCC) to an access node (AN) of a wireless ATM radio communication network (WATM). On the communication connection (WCC) a secret communication key (CK) is used which has been agreed upon by the ATM access node (AN) nd the ATM mobile terminal (MT). Once the operating communication connection (WCC) is established, the mobile terminal (MT) can request authentication information (AI) from the security server (SSD) located in the (WATM) system or another network (FN) connected to the access node (AN). If after setting up the communication connection (WCC) the authentication information (AI) is received in a predetermined time period at said access node (AN) , the mobile terminal is authenticated at the access node (AN). Since the communication channel (WCC) is always setup before the authentication procedure, also security functions from other interconnected networks can be accessed and thus a high level of confidentiality as well as security can be maintained. <IMAGE>
