Abstract
Systems and methods are presented for using a mobile multi-radio access technology (multi-RAT) device for locating an individual, for example, in a search-and-rescue application. The multi-RAT device may permit the individual's cell phone to attach to the mobile multi-RAT device, and then may use a directional antenna to locate the individual. Various embodiments of such a device are described.
Claims20
A method for facilitating search and rescue operations, comprising:
- producing, at a timing source at a first multi-radio access technology (RAT) base station, a timing signal;
- computing, at a processor at the first multi-RAT base station, a location of the mobile device based on a response received from the mobile device at a first directional antenna coupled to the first multi-RAT base station and based on a direction and a beamwidth of the first directional antenna at a time the response is received;
- performing, at the processor at the first multi-RAT base station, a triangulation operation to compute the location of the mobile device based on the timing signal;
- collecting, at a mini-evolved packet core (EPC), a user identifier of the mobile device;
- authenticating, at the first multi-RAT base station using the mini-EPC, the mobile device with the user identifier at the first multi-RAT base station;
- providing, using a second multi-RAT base station, a backhaul connection to the first multi-RAT base station via a mesh network connection with the first multi-RAT base station;
- and
- scanning, at the first multi-RAT base station, a designated area for mobile devices using the first directional antenna to identify locations of a plurality of mobile devices within the designated area.
A non-transitory computer readable storage medium having computer readable code thereon for facilitating search and rescue operations, the medium including instructions executable by one or more processors to perform operations, comprising:
- producing a timing signal with a timing source at a first multi-radio access technology (RAT) base station for connecting with and providing network access to a mobile device;
- computing a location of the mobile device based on a response received from the mobile device at a first directional antenna and based on a direction and a beamwidth of the first directional antenna at a time the response is received, and performing a triangulation operation to compute the location of the mobile device based on the timing signal;
- collecting a user identifier of the mobile device with a mini-evolved packet core (EPC) authenticating the mobile device with the user identifier at the first multi-RAT base station;
- providing a backhaul connection to the first multi-RAT base station by a second multi-RAT base station via a mesh network connection with the first multi-RAT base station;
- and
- scanning a designated area for mobile devices by the first multi-RAT base station using the first directional antenna to and identifying locations of a plurality of mobile devices within the designated area.
