Abstract

The invention relates to a method for transmitting emergency calls by means of a mobile device via a speech channel and a data channel, wherein the data channel serves to transmit location information and wherein additionally the location information is transmitted in encoded form, also via the speech channel and wherein the information is then compared for consistency in the service centre.

Claims

1-21. -21. (canceled)

22. A method for transmitting emergency calls by a mobile device, comprising:

transmitting an emergency call via a speech channel and a data channel, including

transmitting location information via the data channel,

transmitting location information in encoded form via the speech channel, and

comparing the location information transmitted via the speech channel with the location information transmitted via the data channel at the receiver.

23. The method according to claim 22, wherein the location information is transmitted in the form of dual tones multiple frequency (DTMF) tones.

24. The method according to claim 22, wherein the location information is transmitted at the start of the connection.

25. The method according to claim 22, wherein the location information is determined by the base station where the mobile terminal device is registered, in order then to transmit the information via the speech channel.

26. The method according to claim 22, wherein the location information is determined by a GPS receiver in active connection with the mobile device.

27. The method according to claim 26, wherein the comparison is made on the basis of a comparison of geographical coordinates.

28. The method according to claim 22, wherein the comparison is made only for location information which arrives within a predetermined interval.

29. The method according to claim 26, wherein the coordinates are allowed to possess a deviation only within a predetermined tolerance.

30. The method according to claim 27, wherein the coordinates are allowed to possess a deviation only within a predetermined tolerance.

31. The method according to claim 28, wherein the coordinates are allowed to possess a deviation only within a predetermined tolerance.

32. A device for transmitting emergency calls comprising:

a means for transmitting information via a speech channel and a data channel, wherein the means for transmitting uses the data channel for transmitting location information, and the means for transmitting is designed and arranged such that the location information is also transmitted in encoded form via the speech channel.

33. The device according to claim 32, wherein the means for transmitting is present and arranged in order to transmit the location information in the form of DTMF tones.

34. The device according to claim 32, wherein the means are designed and arranged such that the location information is transmitted at the start of the connection.

35. The device according to claim 32, wherein the device is a base station at which a mobile terminal device is registered, in order then to transmit the information via the speech channel.

36. The device according to claim 32, wherein the device is a mobile terminal device which has means for detecting the location information.

37. The device according to claim 36, wherein the location information is determined by a GPS receiver which is in active connection with the mobile terminal device.

38. A receiving device for receiving emergency calls, having means and an apparatus in order to receive information via a speech channel and a data channel, wherein the means use the data channel to receive location information, wherein the means are arranged and designed such that the location information can be received and evaluated both via the data channel and via the speech channel.

39. The receiving device according to claim 38, wherein means are present which compare the location information that has been transmitted via the speech channel with the location information that has been transmitted via the data channel.

40. The receiving device according to claim 39, wherein the comparison is made on the basis of the comparison of geographical coordinates.

41. The receiving device according to claim 39, wherein the comparison is made only for location information that has arrived within a predetermined time interval.

42. The receiving device according to claim 38, wherein the comparison is made only for location information that has arrived within a predetermined time interval.

43. The receiving device according to claim 38, wherein the coordinates are allowed to possess a deviation only within a predetermined tolerance.

44. A data carrier for a computer, characterized by the storage of a data structure which when loaded into a computer and executed on the computer, implements a method for transmitting emergency calls by means of a mobile device via a speech channel and a data channel, wherein the data channel serves to transmit location information, wherein the location information is also transmitted in encoded form via the speech channel and wherein the location information that has been transmitted via the speech channel is compared at the receiver with the location information that has been transmitted via the data channel.

45. A computer system, characterized by an apparatus which permits the carrying out of a method for transmitting emergency calls by means of a mobile device via a speech channel and a data channel, wherein the data channel serves to transmit location information, wherein the location information is also transmitted in encoded form via the speech channel and wherein the location information that has been transmitted via the speech channel is compared at the receiver with the location information that has been transmitted via the data channel.
