Abstract

Simple and multipurpose traffic information is made possible by a method for selecting traffic information which is to be sent to a mobile wireless terminal from a traffic information center and which pertains to a geographic area of a road traffic network selected on the mobile wireless terminal side and/or selected based on the position of the mobile wireless terminal. On the basis of selection information representing the selection of a geographic area, map information pertaining to the selected area is selected in the traffic information center from a digital map of a traffic network, which digital map is available in the traffic information center. On the basis of the selection information, traffic status information pertaining to the geographic area of the road traffic network and representing the traffic status on road sections of the road traffic network are selected from the traffic status information available in the traffic information center. Graphic traffic information based on the selected map information and on the selected traffic status information is transmitted by mobile radio to the mobile wireless terminal for joint graphic display.

Claims

1. A method for selecting traffic information which is to be transmitted to a mobile wireless terminal from a traffic information center, communication between the traffic information center and the mobile wireless terminal taking place over a mobile wireless cell, the method comprising

selecting a geographic area of a road traffic network based on at least one of a selection on the mobile wireless terminal side and the local position of the mobile wireless terminal,

determining selection information representing the selected geographic area on the basis of mobile, wireless cell identity of the mobile wireless cell defined by the mobile wireless network operator,

selecting, on the basis of the selection information, map information from a digital map of a road traffic network, the digital map being available in the traffic information center,

selecting, on the basis of the selection information, traffic status information pertaining to the geographic area of the road network and representing the traffic status on road sections of the road traffic network from traffic status information available in the traffic information center, and

transmitting graphic traffic information based on the selected map information and the selected traffic status information by mobile radio to the mobile wireless terminal for joint graphic display.

2. A method as in claim 1 wherein the transmitting of graphic traffic information to said mobile wireless terminal is carried out by WAP.

3. A method as in claim 1 wherein the selection information is selected on the mobile wireless terminal from a selection menu comprising at least one of a plurality of cities and a plurality of highways and a plurality of highway interchanges and driving directions.

4. A method as in claim 1 wherein the selection information is selected on the mobile wireless terminal by indicating at least one of a highway and a highway interchange.

5. A method as in claim 1 further comprising transmitting the selection information from a mobile wireless network op tor to the traffic information center.

6. A method as in claim 5 further comprising transmitting the information representing the geographic area from the mobile wireless terminal by WAP to the mobile wireless network operator before transmitting to the traffic information center.

7. A method as in claim 1 wherein the selection information is selected based on the local position of the mobile wireless terminal, the local position being determined by a GPS module on the mobile wireless position side, the map information being selected based on the local position.

8. A method as in claim 1 wherein the map information and the traffic status information pertain to one of a predetermined area in a city and a vicinity of the local position which is one of determined on the terminal side and determined on the mobile wireless network operator side and entered on the terminal side.

9. A traffic information center for selecting traffic information which is to be transmitted to a mobile wireless terminal based on selection information representing a geographic area of a road traffic network, communication between the traffic information center and the mobile wireless terminal taking place over a mobile wireless cell, said selection information being based on at least one of a selection on the mobile wireless terminal side and the local position of the mobile wireless terminal, said information center comprising

means for determining selection information representing the selected geographic area on the basis of mobile wire cell identification of the mobile wireless cell defined by the mobile wireless network operator,

means for selecting, on the basis of the selection information, map information from a digital map of a road traffic network, the digital map being available in the traffic information center,

means for selecting, on the basis of the selection information, traffic status information pertaining to the geographic area of the road network and representing the traffic status on road sections of the road traffic network from traffic status information available in the traffic information center, and

means for transmitting graphic traffic information based on the selected map information and the selected traffic status information by mobile radio to the mobile wireless terminal for joint graphic display.

10. A terminal as in claim 9 wherein said graphics display device displays maps of important cities including roads, and displays traffic status information by optically altering relevant sections of the roads by at least one of a colored display and a dashed display and a blinking display.

11. A terminal for displaying traffic information, said terminal comprising

a selection device for selecting information representing a geographic area of a road traffic network,

a mobile wireless reception device for receiving map information and traffic information for said geographic area that is transmitted to it by radio using WAP, and

a graphics display device for joint graphic display of said map information and said traffic status information.

12. A terminal as in claim 11 wherein said selection device comprises a GPS module which permits the local position of the terminal to be determined at a traffic information center, whereby map information and traffic status information for the local position can be received at the terminal from the traffic information center.

13. A terminal as in claim 11 wherein said selection device comprises a menu input device including a keypad.
