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 network device comprising:
a memory that stores executable instructions; and a processor, coupled to the memory, that facilitates execution of the executable instructions to perform operations, comprising: receiving, by a reception component of the network device, information related to a set of radio pairs associated with a set of wireless base station pairs, wherein the set of radio pairs comprises a first pair of radios and a second pair of radios; determining, by an assessment component of the network device, that the first pair of radios and the second pair of radios have a common radio of the set of radio pairs; and determining, by the assessment component of the network device, that a suspect radio of the set of radio pairs has an unstable radio oscillator based on eliminating other radios of the set of radio pairs that are determined to be stable when not paired with the suspect radio and are determined to be unstable when paired with the suspect radio.
