Abstract

A system and method for locating a communication device is disclosed, where an emergency call routine is activated. The routine detects whether at least one communications network is existent at the location of the communication device. In case that more than one communication network is existent, determining a priority of the communications networks is performed. In case only one network is existent, a highest priority is assigned to this network. Consequently, an emergency signal is transmitted over the network with the highest priority.

Claims

1. A method for locating a communication device, whereby an emergency call routine is activated, by which the following steps are performed:

Detecting at least one available communications network at the location of the communication device;

In case that more than one communications network is existent, selecting one of the communications networks;

In case that only one communications network is available selecting this communications network;

Sending an emergency signal over the selected network.

2. The method according to claim 1, whereby at least one of the communications network comprises mobile transceiver or transponder stations, by which the emergency signal from the communication device are further transmitted or that function as a transponder for said emergency signal.

3. The method according to claim 1 or 2, whereby a further network is a cellular network.

4. The method according to any of the previous claims, whereby the emergency call routine also comprises the identification of the communication device.

5. The method according to any of the previous claims, whereby also a speech connection is established over one of the existent communications networks.

6. The method according to any of the previous claims, whereby the emergency call routine can be activated remotely.

7. A Communication device for performing a method according to claims 1 to 6.

8. The communication device according to claim 7, comprising at least two radio modules, one of said radio modules being manually or automatically activable.

9. The communication device according to claim 7 or 8, whereby the method according to claims 1 to 6 can be activated by pushing one button on the communication device.

10. The communication device according to any of the claims 7 to 9, whereby the communication device is a cellular phone.

11. Communications System comprising a communication device according to any of the claims 7 to 10.
