Abstract
Systems and methods are provided for determining that the device is not reporting precise location information, based on output from one or more sensors determining that the device is located indoors and determining the altitude of the device. Based on the determination that the device is located indoors, suspending precise location services until it is determined that the device is back outdoors.
Claims20
A method for determining that a device is located indoors, the method comprising:
- determining that the device is not reporting precise location information to a wireless communications network;
- receiving sensor data from the device, the sensor data from one or more sensors associated with the device;
- and
- determining, using the sensor data, that the device is located indoors.
A system for determining a location of a device, the system comprising:
- one or more processors;
- and
- one or more non-transitory computer storage hardware devices storing computer-usable instructions that, when used by the one of more processors, cause the one or more processors to:
- determine that the device is not reporting precise location information to a wireless communications network;
- receive sensor data from the device, the sensor data from one or more sensors associated with the device;
- and
- determine, using the sensor data, that the device is located inside a structure.
One or more non-transitory computer-readable media having computer-usable instructions embodied thereon that, when executed by one or more processors, cause the processors to:
- determine that the device is not receiving precise location information from a wireless communications network;
- send sensor data to the wireless communications network, the sensor data from one or more sensors associated with the device;
- and
- determine, using the sensor data, that the device is located indoors.
