Embodiment Construction

[0033] In order to clearly describe the technical solution of the present invention, the communication device configuration information that is the basis of the technical solution of the present invention is firstly introduced as follows:

[0034] The communication equipment involved in the present invention is composed of one FRU or a plurality of interconnected FRUs; for the components of these FRUs, see figure 2 , image 3 , can be a circuit unit capable of completing basic electrical functions, or a combination of these circuit units and FRU. Although these circuit units are the objects that need to be paid attention to when locating faults, in order to quickly replace the faulty parts when a fault occurs and make the communication equipment work in a good state, communication network managers usually pay more attention to those FRU composed of circuit units. These FRUs, that is, physical entities concerned by fault location may be nodes: physical entities concerned by ...

Abstract

This invention relates to a method and a system for fault localization of communication equipment including: obtaining internal test imformation of changeable units at site of equipment, searching forall unit circuits correlated with test information based on the test information and associated matrix describing the communication equipment to further search for the test information associated with the unit circuit in the unit circuit set based on the unit circuit and the associated matrix to set up a localized sub-matrix by the searched unit circuit set and the test information set and judgeand register the unit circuits with abnormal working state and register the corresponding FRU, which associates test or alarming information with the FRU circuit unit to localize faulty FRU automatically to overcome the shortcoming of unabling localizing fault quickly.

Description

technical field [0001] The invention relates to an automatic fault location technology, in particular to a method and system for fault location of communication equipment, belonging to the technical field of communication. Background technique [0002] Component failure, software defects, cable aging, human error and many other factors will cause communication equipment to malfunction during operation, and the communication services provided by communication equipment will also be interrupted or abnormal. When the communication equipment breaks down, the failure should be located as soon as possible, so as to eliminate the failure as soon as possible, restore the normal operation of the communication equipment, and ensure the normal communication services provided by the communication equipment. [0003] The main purpose of fault location is to provide guiding information for troubleshooting. A general requirement is to locate the fault to a field replaceable unit (Field Re...
