Abstract
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.

4. A wireless terminal enabling its user to establish an emergency connection in a wireless local network, wherein the user is a non-subscriber to the local network, comprising a processor configured to:
-
recognize a number as an emergency number when the user has entered an emergency telephone number, and send a start-up message from the terminal to a radio access point of the network; receive from the access point of the network a response message requesting the identity of the terminal; send from the terminal to the access point a message containing the identity of the terminal and an indication signifying that the start-up message is for an emergency call; receive an acceptance message via the access point, wherein the acceptance message facilitates validating a port of the access point in order to enable the terminal to establish an emergency connection across the local network; and send to the access point a message requesting establishment of an emergency connection over the local network. - View Dependent Claims (5, 6, 7)

14. A method for use at a calling wireless terminal to enable the calling wireless terminal to establish an emergency connection in a local network when the calling wireless terminal is not subscribed to the local network, the method comprising, when an emergency telephone number is indicated at the calling wireless terminal as a called destination:
-
recognizing the number as an emergency number at the calling wireless terminal, and, in response to such recognition, sending a start-up message from the calling wireless terminal toward a radio access point of the network; receiving at the calling wireless terminal a message requesting the identity of the calling wireless terminal, said message requesting the identity of the calling wireless terminal having been originated at the radio access point and having been sent toward the calling wireless terminal in response to the start-up message; sending from the calling wireless terminal toward the radio access point of the network, in response to receipt of the message requesting the identity of the calling wireless terminal, a message which includes the identity of the terminal and an indication signifying that the message including the identity of the calling wireless terminal is for an emergency call; receiving at the calling wireless terminal an acceptance message originated at an authentication server; and establishing an emergency connection from the calling wireless terminal and to the local network. - View Dependent Claims (15)

16. A method enabling a calling wireless terminal to establish an emergency connection in a local network including an authentication server, wherein the calling wireless terminal is not subscribed to the local network, the method comprising, when an emergency telephone number is specified as a called destination:
-
receiving, at the authentication server, a message which includes the identity of the calling wireless terminal and an indication signifying that the message including the identity of the calling wireless terminal relates to an emergency call, the message including the identity of the calling wireless; transmitting from the authentication server an acceptance message, the acceptance message indicating that the authentication server has determined that the message including the identity of the calling wireless terminal relates to an emergency call. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. An apparatus for use in a calling wireless terminal to enable the calling wireless terminal to establish an emergency connection in a local network when the calling wireless terminal is not subscribed to the local network and when an emergency telephone number is indicated at the calling wireless terminal as a called destination, the apparatus comprising:
-
means for recognizing the number as an emergency number at the calling wireless terminal, and, in response to such recognition, sending a start-up message from the calling wireless terminal toward a radio access point of the network; means for receiving at the calling wireless terminal a message requesting the identity of the calling wireless terminal, said message requesting the identity of the calling wireless terminal having been originated at the radio access point and having been sent toward the calling wireless terminal in response to the start-up message; means for sending from the calling wireless terminal toward the radio access point of the network, in response to receipt of the message requesting the identity of the calling wireless terminal, a message which includes the identity of the terminal and an indication signifying that the message including the identity of the calling wireless terminal is for an emergency call; means for receiving at the calling wireless terminal an acceptance message originated at an authentication server; and means for establishing an emergency connection from the calling wireless terminal to the local network.
