Abstract

A method allows a user to transmit emergency messages to a selected communication network, in particular a WiMax network, even without valid registration.

Claims

1. A method for forwarding emergency messages from a terminal in a communication network with an access network, comprising:

using a network access identifier to identify the emergency messages from the terminal;

recognizing the emergency messages as such at the access network on the basis of the network access identifier; and

forwarding the emergency messages from the access network to an emergency connectivity services network, wherein

the network access identifier has a character string for identifying the terminal and a character string for addressing the emergency connectivity services network,

the network access identifier includes characters for identification of a user profile,

the access network and/or the emergency connectivity services network identify the user profile on the basis of the network access identifier, and

the user profile is used to set parameters for a communication link between the terminal and the emergency connectivity services network.

2. The method as claimed in claim 1, wherein

the communication network is a Worldwide Interoperability for Microwave Access (WiMAX) radio network.

3. The method as claimed in claim 1, wherein

the terminal is not registered in the communication network, and

an authentication server of the access network recognizes the emergency message on the basis of the network access identifier and registers the terminal in the communication network.

4. The method as claimed in claim 1, wherein

the terminal is not registered in the communication network,

the access network recognizes the emergency messages on the basis of the network access identifier and forwards the emergency messages to an authentication server of an emergency connectivity services network,

the authentication server of the emergency connectivity services network registers the terminal in the communication network.

5. The method as claimed in claim 1, wherein

the terminal is registered in the communication network, and

the access network recognizes the emergency messages on the basis of the network access identifier and forwards the emergency messages to the emergency connectivity services network.

6. The method as claimed in claim 1, wherein

the terminal is not registered in the communication network, and

the access network authenticates and/or authorizes the terminal on the basis of a device authentication.

7. The method as claimed in claim 1, wherein

the emergency connectivity services network and the access network both have an authentication server,

the access network and/or the authentication server of the access network registers with the emergency connectivity services network, and

the authentication server of the emergency connectivity services network accepts emergency messages if the access network and/or the authentication server of the access network is authorized.

8. A system for forwarding emergency messages from a terminal in a communication network, with the emergency messages of the terminal being identified by a network access identifier, comprising:

an access network which recognizes the emergency messages as such on the basis of the network access identifier; and

an emergency connectivity services network, to which recognized emergency messages are forwarded from the access network, wherein

the network access identifier has a character string for identifying the terminal and a character string for addressing the emergency connectivity services network,

the network access identifier includes characters for identification of a user profile,

the access network and/or the emergency connectivity services network identify the user profile on the basis of the network access identifier, and

the user profile is used to set parameters for a communication link between the terminal and the emergency connectivity services network.

9. A mobile terminal comprising:

means for recognizing a message as an emergency message;

means for identifying the emergency message as such with a network access identifier; and

a transmitter to transmit the emergency message and the network access identifier to an emergency connectivity services through an access network, wherein

the network access identifier has a character string for identifying the mobile terminal,

the network access identifier includes characters for identification of a user profile,

the access network and/or the emergency connectivity services network identify the user profile on the basis of the network access identifier, and

the user profile is used to set parameters for a communication link between the terminal and the emergency connectivity services network.
