Method that enables the user of a wireless telephone terminal to establish an emergency connection in a local network, and terminal and server for carrying out this method

An authentication server for setting up an emergency connection for a user of a wireless telephone terminal in a local network, wherein the user is a non-subscriber to local network, comprising a processor configured to, when the user has entered an emergency telephone number:

• receive a message containing identity of a terminal and an indication signifying that it is an emergency call from the access point at the authentication server;
• recognize, in the authentication server, that the message comprises an indication signifying that it is an emergency call;
• and
• send an acceptance message to the terminal;
• wherein an emergency telephone number entered by the user is not transmitted with the message containing the identity information and the indication signifying that it is an emergency call from the access point to the authentication server.

A method for establishing an emergency connection for a calling wireless terminal 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.

An apparatus for establishing an emergency connection for a calling wireless terminal 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:

• a processor configured to recognize 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;
• a receiver configured to receive 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;
• a transmitter configured to transmit 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;
• wherein the receiver is further configured to receive at the calling wireless terminal an acceptance message originated at an authentication server;
• and
• wherein the processor is further configured to establish an emergency connection from the calling wireless terminal to the local network.
