Abstract

Apparatus, methods and systems relating to providing vehicular traffic information through a wireless telecommunications network. An exemplary system includes a geographic location system (GLS), a database containing vehicular roadway information, and a vehicular traffic determination node. The GLS is operative to determine the approximate physical location of at least one Mobile Station (MS) in communication with the wireless telecommunications network. The vehicular traffic determination node is operative to i) receive and correlate the approximate physical location of the MS to the vehicular roadway information to generate vehicular traffic information, and ii) communicate the vehicular traffic information to the wireless telecommunications network; the wireless telecommunications network can selectively-transmit or broadcast the vehicular traffic information.

Claims

1. A system for providing vehicular traffic information to a Mobile Station (MS) through a wireless telecommunications network said system comprising:

an event detector, said event detector operative to detect a predefined event associated with said MS. said predefined event being selected from the group consisting of;

the origination of a wireless call by said MS;

the origination of a wireless call to said MS;

the termination of a wireless call by said MS;

the termination of a wireless call to said MS;

the receipt of Short Message Service (SMS) information by said MS; and

a periodic location update of said MS;

a geographic location system (GLS), said GLS operative to determine the approximate physical location of at least one MS upon the receipt of a signal from said event detector, said event detector sending said signal upon the occurrence of said predefined event;

a database containing vehicular roadway information; and

a vehicular traffic determination node coupled to said database, said vehicular traffic determination node operative to;

i) receive and correlate said approximate physical location of said at least one MS to said vehicular roadway information to generate said vehicular traffic information, and

ii) communicate said vehicular traffic information to said wireless telecommunications network.

2. The system recited in claim 1, wherein said GLS utilizes Time Difference of Arrival (TDOA) signaling techniques to determine said approximate physical location.

3. The system recited in claim 1, wherein said GLS utilizes Angle of Arrival (AOA) signaling techniques to determine said approximate physical location.

4. The system recited in claim 1, wherein said GLS comprises a satellite-based Global Positioning System.

5. The system recited in claim 1, wherein said wireless telecommunications network comprises a Public Land Mobile Network (PLMN).

6. The system recited in claim 1, wherein said vehicular roadway information includes data selected from the group consisting of:

physical locations of vehicular roadways;

number of traffic lanes of each said vehicular roadway; and

nominal speed limits of each said vehicular roadway.

7. The system recited in claim 1, wherein said vehicular traffic information includes data selected from the group consisting of:

a physical roadway location of a vehicle associated with said at least one MS;

a maximum speed of a vehicle associated with said at least one MS;

a minimum speed of a vehicle associated with said at least one MS; and

an average speed of a vehicle associated with said at least one MS.

8. A method for providing vehicular traffic information to a Mobile Station (MS) in a wireless telecommunications network, said method comprising the steps of:

determining the approximate physical location of at least one MS using a geographic location system (GLS), wherein said GLS determines said approximate physical location as a function of a predefined event associated with said MS, said predefined event being selected from the group consisting of;

the origination of a wireless call by said MS;

the origination of a wireless call to said MS;

the termination of a wireless call by said MS;

the termination of a wireless call to said MS;

the receipt of Short Message Service (SMS) information by said MS; and

a periodic location update of said MS;

retrieving vehicular roadway information from a database;

correlating said approximate physical location of said at least one MS to said vehicular roadway information to generate said vehicular traffic information; and

, communicating said vehicular traffic information to a MS through said wireless telecommunications network.

9. The method recited in claim 8, wherein said GLS utilizes Time Difference of Arrival (TDOA) signaling techniques to determine said approximate physical location.

10. The method recited in claim 8, wherein said GLS utilizes Angle of Arrival (AOA) signaling techniques to determine said approximate physical location.

11. The method recited in claim 8, wherein said GLS utilizes a satellite-based Global Positioning System to determine said approximate physical location.

12. The method recited in claim 8, wherein said wireless telecommunications network comprises a Public Land Mobile Network (PLMN).

13. The method recited in claim 8, wherein said vehicular roadway information includes data selected from the group consisting of:

physical locations of vehicular roadways;

number of traffic lanes of each said vehicular roadway; and

nominal speed limits of each said vehicular roadway.

14. The method recited in claim 8, wherein said vehicular traffic information includes data selected from the group consisting of:

a physical roadway location of a vehicle associated with said at least one MS;

a maximum speed of a vehicle associated with at said at least one MS;

a minimum speed of a vehicle associated with said at least one MS; and

an average speed of a vehicle associated with said at least one MS.

15. A vehicular traffic determination node for providing vehicular traffic information to a Mobile Station (MS) through a wireless telecommunications network, said vehicular traffic determination node operative to:

i) receive the approximate physical location of at least one MS from a geographic location system (GLS), wherein said GLS determines said approximate physical location as a function of a predefined event associated with said MS, said predefined event being selected from the group consisting of;

the origination of a wireless call by said MS;

the origination of a wireless call to said MS;

the termination of a wireless call by said MS;

the termination of a wireless call to said MS;

the receipt of Short Message Service (SMS) information by said MS; and

a periodic location update of said MS;

ii) correlate said approximate physical location of said at least one MS to vehicular roadway information to generate said vehicular traffic information; and

iii) communicate said vehicular traffic information to said wireless telecommunications network.

16. The vehicular traffic determination node recited in claim 15, wherein said vehicular roadway information includes data selected from the group consisting of:

physical location s of vehicular roadways;

number of traffic lanes of each said vehicular roadway; and

nominal speed limits of each said vehicular roadway.
