<p>When establishing an emergency connection in a wireless network having an authentication server, wherein a user terminal is a non-subscriber to the network, a dialed number is recognized as an emergency number and the terminal sends a start-up message to a radio access point of the network. The terminal receives a first message that requests the identity of the terminal, from the access point in response to the start-up message, and sends a second message, which contains the identity of the terminal and an indication indicating that the terminal is attempting to make an emergency call. An authentication server, determines that the second message contains an indication that the call is an emergency call, and sends an acceptance message to the terminal via the access point wherein a port of the access point is validated to permit the terminal to establish an emergency connection.</p> |
