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.
Claims20
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;
- detecting, based on the first plurality of signals, that a 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;
- and
- determining a second location of the communication device based on the second plurality of signals.
A non-transitory, 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:
- transmitting a first plurality of signals via a unicast transport technology;
- 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;
- and
- determining a second location of the communication device based on the second plurality of signals, wherein the determining a second location comprises receiving from the communication device a computed location of the communication device, applying an error correction to the computed location to generate a corrected location, and transmitting the corrected location to the communication device.
A method, comprising:
- transmitting, by a processing system including a processor, a first plurality of signals via a unicast transport technology;
- detecting, based on the first plurality of signals, that a 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;
- determining a second location of the communication device based on the second plurality of signals;
- and
- responsive to receiving of error correction data from at least one reference node of a network, transmitting, by the processing system, 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.
