Method and system for detecting link failure

Abstract

The invention discloses a method and a system used for link failure detection. By a failure detection triggering mechanism, a physical layer of the system or the upper layer link state thereof is used as a criterion; conditions used for deciding whether a circulating test is started or not are carried out according to a certain given standard threshold value; when conditions are complied with, the system automatically loads a positioning circulating test program, failure positioning of the current link is carried out, therefore, the method and the system have extremely good real-time characteristic and completeness, can greatly save the maintenance cost during positioning the link failure, can reduce the manpower investment and time investment, can meet the requirement of the user on real-time characteristic for positioning the failure, and can improve the customer satisfaction.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for link fault detection. Background technique [0002] In the wireless access system of the wireless communication system, the communication link is often subject to various interferences, and the system itself may also have potential fault defects. etc.), it must be able to accurately test the link in real time without affecting the business, and accurately locate the cause (or location) of the failure in the system, so that the system itself and the peripheral equipment of the system (such as external transmission equipment etc.) to improve. [0003] At present, the test technologies used in the wireless access system mainly include the test technology of manual participation and the test technology of timing polling. [0004] In the way of manual participation to start and execute the link quality test and locate the link fault test method, it can be divided in...

AI Technical Summary

Problems solved by technology

[0007] The defect of the manual command test method is that when the communication link fails, the on-site operator is required to be on site in real time, and to a large extent it depends on the operator's rich experience and high skills to correctly judge the current situation. The degree of impact of the failure on the business

Due to the uncertainty of link failures, it is difficult for operators to operate on site in real time

[0008] The defect of the manual external test equipment test method is that, first of all, the fault location test cannot be performed in real time at the time of the fault. Since many faults occur randomly and the duration is not very long, the fault is not necessarily reproduced during the test. , to a large extent, this kind of test loses the meaning of positioning, and then disconnecting the original interface of the system and connecting to an external test device will have a great impact on the system, causing system business interruption, which is generally a last resort only when

[0009]The system regularly starts the test method, and the test will be carried out when the test is not needed, which will cause unnecessary increase in the system flow and cannot be started in time when the failure occurs test

Sometimes the fault lasts for a long time, and sometimes it occurs randomly. For the location of uncertain faults, this timing start test method cannot meet the location requirements.
