US 2014/0004848 A1 · DETECTION OF FAULTY RADIO OSCILLATOR OR FAULTY MOBILE TIMING MEASUREMENTS

Abstract

Detection of a faulty radio oscillator is provided herein. Also provided herein is detection of faulty mobile timing measurements. Timing measurements, as observed by a mobile device, and an identification of primary scrambling codes associated with the timing measurements are captured. The primary scrambling codes match each timing measurement with a particular radio. The mobile device can also report its location information. Radios for which timing measurements have been received are paired. Based on the paired radios and an associated observed time delay derived from the timing measurements, comparisons can be made between paired radios having at least one common radio. Radios exhibiting an expected timing value can be removed from the analysis in order to isolate a radio that has a faulty radio oscillator.

Dependent claims

A system comprising:

at least one memory that stores computer-executable instructions;
at least one processor, communicatively coupled to the at least one memory, that facilitates execution of the computer-executable instructions to at least:
obtain, from a first mobile device, a first set of timing measurements for a first set of radios and a first location of the first mobile device;
obtain, from a second mobile device, a second set of timing measurements for a second set of radios and a second location of the second mobile device;
determine radio pairs from the first set of timing measurements and the second set of timing measurements;
and
evaluate a subset of the radio pairs from the determined radio pairs relative to other radio pairs having a common radio to isolate a radio having a faulty radio oscillator based on respective timing measurements and respective locations of radios of the subset of the radio pairs.
