Abstract
Aspects of the subject disclosure may include, for example, systems and methods for dynamically applying Received Signal Time Difference (RSTD) locating in mobile networks, thereby accurately determining mobile device locations while conserving radio resources. A last known location database is accessed, coordinates are converted into a geographic bin, and base stations are instructed to transmit RSTD signals only when needed, enhancing location accuracy for various applications without constant resource consumption. 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:
- accessing, by a locating service, a last known location database to retrieve a latitude and a longitude associated with a mobile device;
- converting, by the locating service, the latitude and the longitude into a geographic bin;
- identifying, by the locating service, a set of base station radios that provide service in an area associated with the geographic bin;
- instructing, by the locating service, the set of base station radios to transmit Received Signal Time Difference (RSTD) signals;
- and
- instructing, by the locating service, the mobile device to search for the RSTD signals.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- determining a last known location of a mobile device;
- converting the last known location of the mobile device into a geographic bin;
- identifying at least one base station that provides service in an area associated with the geographic bin;
- instructing the at least one base station to transmit Received Signal Time Difference (RSTD) signals;
- and
- instructing the mobile device to search for the RSTD signals.
A method, comprising:
- receiving, by a processing system including a processor, a trigger event to locate a mobile device, wherein the trigger event includes an identifier of the mobile device;
- determining, by the processing system, a last known location of the mobile device;
- converting, by the processing system, the last known location of the mobile device into a geographic bin;
- identifying, by the processing system, at least one base station that provides service in an area associated with the geographic bin;
- instructing, by the processing system, the at least one base station to transmit Received Signal Time Difference (RSTD) signals;
- and
- instructing, by the processing system, the mobile device to search for the RSTD signals.
