Detection of faulty radio oscillator or faulty mobile timing measurements

摘要

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.

1. A system comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving information related to base station radio pairs comprising a first base station radio pair that further comprises a first base station radio and a second base station radio, and a second base station radio pair that further comprises a third base station radio; anddetermining a first likelihood that a suspect radio of the base station radio pairs comprises an unstable radio oscillator via elimination of another base station radio of the base station radio pairs that is determined to satisfy a rule related to a second likelihood that the other base station radio is stable when not paired with the suspect radio and is determined to satisfy another rule related to a third likelihood that the other base station radio is unstable when paired with the suspect radio.
