Abstract
Systems and methods for determining a location of a mobile computing device requesting emergency services are provided. A mobile computing device may receive an indication of a request for emergency services from a user of the mobile computing device. The mobile computing device may receive a first wireless signal from a first device. The wireless signal may include an indication of a first geographic position associated with the first device. The mobile computing device may determine a location associated with the mobile computing device based on the indication of the first geographic position associated with the first device, and may send the determined location to a provider of emergency services.
Claims19
A computer-implemented method, comprising:
- receiving, by a mobile computing device, an indication of a request for emergency services from a user of the mobile computing device;
- responsive to a failure of the mobile computing device to determine a location associated with the mobile computing device within an accuracy threshold based on a GPS signal:
- searching, by the mobile computing device, for a first wireless signal including an indication of a first geographic position associated with the first device;
- receiving, by the mobile computing device, the first wireless signal from the first device, the first wireless signal including an indication of the first geographic position associated with the first device;
- determining, by the mobile computing device, the location associated with the mobile computing device based on the indication of the first geographic position associated with the first device;
- and
- sending, by the mobile computing device, the determined location to a provider of emergency services.
A computer-implemented method, comprising:
- receiving, from a mobile computing device, an indication of a request for emergency services;
- responsive to a failure to determine a location associated with the mobile computing device within an accuracy threshold based on a GPS signal received by the mobile computing device:
- sending, to the mobile computing device, a request for the indication of the first wireless signal including the indication of the first geographic position associated with the first device;
- receiving, from the mobile computing device, an indication of the first wireless signal received by the mobile computing device from the first device, the first wireless signal including an indication of the first geographic position associated with the first device;
- determining the location associated with the mobile computing device based on the indication of the first geographic position associated with the first device;
- and
- sending the determined location to a provider of emergency services.
A system including:
- a device associated with a first geographic position and configured to send a wireless signal including an indication of the first geographic position to mobile computing devices;
- one or more processors;
- and
- a non-transitory program memory communicatively coupled to the one or more processors and storing executable instructions that, when executed by the one or more processors, cause the processors to:
- receive an indication of a request for emergency services associated with a mobile computing device, including an indication of the device;
- responsive to a failure to determine a location associated with the mobile computing device within an accuracy threshold based on a GPS signal received by the mobile computing device:
- send, to the mobile computing device, a request for the indication of the first wireless signal including the indication of the first geographic position associated with the first device;
- determine a location associated with the mobile computing device based on the indication of the geographic position associated with the device;
- and
- send the determined location to a provider of emergency services.
