Time distance of arrival based mobile device location detection with disturbance scrutiny

A method, comprising:

• receiving, by a system comprising a processor, signal information from a mobile device indicating arrival times of signals received by the mobile device from respective base station devices of a group of base station devices;
• determining, by the system using a closed form hyperbolic curve function, intersection points between hyperbolic curves generated based on the signal information and base station location information identifying respective locations of the base station devices;
• determining, by the system using the closed form hyperbolic curve function, disturbed intersection points between disturbed hyperbolic curves generated based on the signal information as modified based on a deliberate error value;
• determining, by the system, a degree of robustness of respective intersection points of the intersection points based on differences between the respective intersection points and corresponding disturbed intersection points of the disturbed intersection points;
• and
• determining, by the system, a location of the mobile device based on robust intersection points of the intersection points that are associated with at least a defined degree of robustness.

A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• receiving signal information from a mobile device indicating arrival times of signals received by the mobile device from respective base station devices included in a group of base station devices;
• determining, using a closed form function, intersection points between hyperbolic curves generated based on the signal information and base station location information identifying respective locations of the base station devices;
• determining, using the closed form function, disturbed intersection points between disturbed hyperbolic curves generated based on the signal information as modified based on a deliberate error value;
• determining a degree of robustness of respective intersection points of the intersection points based on differences between the respective intersection points and corresponding disturbed intersection points of the disturbed intersection points;
• and
• determining a location of the mobile device based on a robust intersection point of the intersection points based on the robust intersection point being determined to have an acceptable degree of robustness.
