Abstract

A method computer aided dispatching. The present method includes providing a display 510 having a first display segment 530. The first display segment 530 includes a digitized representation of a selected area from a raster map, intelligent area data superimposed upon the selected area to provide intelligence, and a user locatable mark 520. The user locatable mark 520 defines a mobile unit position based upon a first value and a second value. The present method also includes using a dispatch system 811 operably coupled to the display. The dispatch system 811 includes order data from customers. A portion of the order data is transferred from a data acquisition 801, 808 device to the mobile unit 610.

Claims

1. An apparatus comprising:

a plurality of mobile units, the mobile units each including a communication device and a navigation tracking device, the navigational tracking device including a microprocessor operably coupled to a global positioning system (GPS) navigational sensor and a mobile radio modem operably coupled to the microprocessor; and

a computer aided dispatch system, the computer aided dispatch system comprising order data from customers, the order data having a portion being transferred from a data acquisition device coupled to the computer aided dispatch system to the mobile unit communication device.

2. The apparatus of claim 1 wherein the mobile unit communication device transfers information via radio frequencies.

3. The apparatus of claim 1 wherein the mobile unit communication device transfers information via a tool selected from a group comprising a cellular telephone, frequency modulated (FM) carrier means, cellular digital packet data means (CDPD), satellite communication, and a wide area wireless communication network (WAN).

4. The apparatus of claim 1 wherein the mobile unit communication device is an item selected from a group comprising a telephone line, a wide area network, a local area network, and a pager.

5. The apparatus of claim 1 wherein the computer aided dispatch system is further configured to provide a schedule to the mobile unit, the schedule comprising route information and order data.

6. The apparatus of claim 1 wherein the computer aided dispatch system is further configured to provide a route from the computer aided dispatch system, the route comprising street data from a vector text information.

7. The apparatus of claim 6 wherein the vector text information comprises a street name.

8. The apparatus of claim 6 wherein the vector text information comprises a block number.

9. The apparatus of claim 6 wherein the vector text information comprises a major street cross-section.

10. The apparatus of claim 1 wherein information about each of the mobile units is represented by an icon on a display operably coupled to the computer aided dispatch system.

11. The apparatus of claim 1 wherein the computer aided dispatch system includes data related to a position of each one of the mobile units, the position data comprising a first value and a second value, the first value being a latitude position and the second value being a longitude position.

12. The apparatus of claim 11 wherein the navigational tracking device supplies the position data.

13. A computer aided dispatching method comprising:

operating a plurality of mobile units, the mobile units each including a communication device and a navigation tracking device, the navigational tracking device including a microprocessor operably coupled to a global positioning system (GPS) navigational sensor and a mobile radio modem operably coupled to the microprocessor; and

operating a computer aided dispatch system, the computer aided dispatch system comprising order data from customers, the order data having a portion being transferred from a data acquisition device coupled to the computer aided dispatch system to the mobile unit communication device.

14. The method of claim 13 wherein the mobile unit communication device transfers information via radio frequencies.

15. The method of claim 13 wherein the mobile unit communication device transfers information via a tool selected from a group comprising a cellular telephone, frequency modulated (FM) carrier means, cellular digital packet data means (CDPD), satellite communication, and a wide area wireless communication network (WAN).

16. The method of claim 13 wherein the mobile unit communication device is an item selected from a group comprising a telephone line, a wide area network, a local area network, and a pager.

17. The method of claim 13 further comprising providing a schedule from the computer aided dispatch system, the schedule comprising route information and order data.

18. The method of claim 13 further comprising providing a route from the computer aided dispatch system, the route comprising street data from a vector text information.

19. The method of claim 18 wherein the vector text information comprises a street name.

20. The method of claim 18 wherein the vector text information comprises a block number.

21. The method of claim 18 wherein the vector text information comprises a major street cross-section.

22. The method of claim 13 wherein information about each of the mobile units is represented by an icon on a display operably coupled to the computer aided dispatch system.

23. The method of claim 13 further comprising using a two-way messaging device for communicating to one of the plurality of mobile units.

24. The method of claim 13 wherein the computer aided dispatch system includes data related to a position of each one of the mobile units, the position data comprising a first value and a second value, the first value being a latitude position and the second value being a longitude position.

25. The method of claim 24 wherein the navigational tracking device supplies the position data.
