Abstract

Aspects of the subject disclosure may include, for example, computing a first location of a processing system, receiving first data via a unicast transport technology at a first rate, computing a first corrected location of the processing system in accordance with the first location and the first data, receiving second data via a broadcast transport technology, a multicast transport technology, or a combination thereof, at a second rate that is less than the first rate, and computing a second corrected location of the processing system in accordance with the second data. Other embodiments are disclosed.

First claim

What is claimed is:

1. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
transmitting a first plurality of signals via a unicast transport technology at a first rate of signaling;
detecting, based on the first plurality of signals, that a determined first location of a communication device that receives the first plurality of signals is accurate within a threshold amount;
responsive to the detecting, transmitting a second plurality of signals via a broadcast transport technology, a multicast transport technology, or a combination thereof, at a second rate of signaling, wherein the second rate of signaling is less than the first rate of signaling; and
determining a second location of the communication device based on the second plurality of signals.

2. The device of claim 1 , wherein the determining of the second location of the communication device comprises:
receiving from the communication device a computed location of the communication device as computed by the communication device;
responsive to the receiving, applying an error correction to the computed location to generate a corrected location; and
transmitting the corrected location to the communication device to cause the communication device to present the corrected location.

3. The device of claim 2 , wherein the operations further comprise:
receiving error correction data from at least one reference node of a network,
wherein the applying of the error correction is responsive to the receiving of the error correction data.

4. The device of claim 1 , wherein the transmitting of the first plurality of signals occurs over a data plane of a network.

5. The device of claim 1 , wherein the transmitting of the second plurality of signals occurs over a control plane of a network.

6. The device of claim 1 , wherein the operations further comprise:
receiving error correction data from at least one reference node of a network; and
responsive to the receiving of the error correction data, transmitting the error correction data to the communication device to cause the communication device to apply an error correction to a computed location of the communication device to generate a corrected location of the communication device.

7. The device of claim 6 , wherein the detecting that the determined first location of the communication device is accurate within the threshold amount is in accordance with a magnitude associated with the error correction data.

8. The device of claim 1 , wherein the communication device comprises a mobile communication device, and wherein the second location is different from the determined first location.

9. The device of claim 1 , further comprising:
receiving the first plurality of signals from at least one reference node of a network.

10. The device of claim 9 , wherein the at least one reference node has a fixed position.

11. A machine-readable medium, comprising executable instructions that, when executed by a first processing system including a first processor, facilitate performance of operations, the operations comprising:
receiving a plurality of signals from a plurality of satellites;
responsive to the receiving of the plurality of signals, computing a first location of the first processing system;
receiving first error correction data from a second processing system that includes a second processor via a unicast transport technology at a first rate of signaling;
responsive to the receiving of the first error correction data, applying the first error correction data to the first location to generate a first corrected location of the first processing system; and
subsequent to the receiving of the first error correction data, receiving second error correction data from the second processing system via a broadcast transport technology, a multicast transport technology, or a combination thereof.

12. The machine-readable medium of claim 11 , wherein the operations further comprise:
responsive to the receiving of the second error correction data, applying the second error correction data to the first corrected location of the first processing system to generate a second corrected location of the first processing system.

13. The machine-readable medium of claim 11 , wherein the second error correction data is received at a second rate of signaling that is different from the first rate of signaling.

14. The machine-readable medium of claim 13 , wherein the second rate of signaling is less than the first rate of signaling.

15. The machine-readable medium of claim 11 , wherein the receiving of the first error correction data occurs over a data plane of a network.

16. The machine-readable medium of claim 15 , wherein the receiving of the second error correction data occurs over a control plane of the network.

17. The machine-readable medium of claim 11 , wherein the first processing system includes an output device, and wherein the operations further comprise:
presenting, by the output device, the first corrected location as a first indication of a first position of a motor vehicle communicatively coupled with the first processing system.

18. The machine-readable medium of claim 17 , wherein the output device comprises a display device, a speaker, or a combination thereof, and wherein the presenting of the first corrected location as the first indication of the first position of a motor vehicle comprises presenting the first indication as a graphic on the display device, as an auditory notification over the speaker, or a combination thereof, and wherein the operations further comprise:
presenting, by the output device, a second indication of a second location of the motor vehicle, wherein the second location corresponds to a destination of the motor vehicle; and
presenting, by the output device, directions for operating the motor vehicle to enable an arrival of the motor vehicle at the destination from the first corrected location.

19. A method, comprising:
computing, by a processing system including a processor, a first location of the processing system;
receiving, by the processing system, first data via a unicast transport technology at a first rate;
generating, by the processing system, a first corrected location of the processing system in accordance with the first location and the first data;
receiving, by the processing system, second data via a broadcast transport technology, a multicast transport technology, or a combination thereof, at a second rate that is less than the first rate; and
generating, by the processing system, a second corrected location of the processing system in accordance with the second data.

20. The method of claim 19 , wherein the generating of the second corrected location is further in accordance with the first corrected location, and wherein the method further comprises:
decompressing, decrypting, and decoding, by the processing system, the first data to generate decompressed, decrypted, and decoded first data, wherein the generating of the first corrected location is further in accordance with the decompressed, decrypted, and decoded first data;
generating, by the processing system, a first indication of the first corrected location and a second indication of the second corrected location;
presenting, by the processing system, the first indication on an output device at a first point in time; and
