Facilitation of delay error correction in timing-based location systems |
摘要 |
Computation of delay error offset information is facilitated. A method can include receiving measurement information indicative of a location of a mobile device, calibrating the measurement information resulting in calibrated measurement information, comparing the calibrated measurement information and historical calibrated measurement information, and computing a measurement error based, at least, on the comparing, wherein the measurement error includes delay error offset information. |

1. A method, comprising:
comparing, by a system comprising a processor, calibrated measurement information and historical calibrated measurement information, wherein the calibrated measurement information and the historical calibrated measurement information are associated with measurement information indicative of a location of a mobile device; and determining, by the system, a measurement error based on a result of the comparing, wherein the measurement error comprises delay error offset information. |
