On-line malfunction detecting system, device and method

Abstract

The example of the invention provides a system, a device and a method for checking on-line faults, the system comprises a first checkout gear of a sending end and a second checkout gear of a receiving end, wherein the method comprises obtaining a checking valueV1 through using the first checkout gear to check and calculate data when in check and inserting the checking value which is obtained by calculation into the data and sending to the receiving end, obtaining a checking value V2 through using the second checkout gear to check and calculate the data which is received by the receiving end, obtaining a checking value VI' which is received by the receiving end and is from the sending end, comparing the checking value V2 and the checking value VI', judging the data which is received is correct if the checking value V2 is same with the checking value VI', and otherwise judging the data which is received is wrong. A scheme for checking the on-line faults, which is provided by the exampleof the invention supports on-line checks, a detecting instrument does not need adopting additionally, and superjacent bed protocol support does not need, which is convenient for realizing and does not affect the business processing performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication fault detection system, device and method. Background technique [0002] In the communication network, it is often necessary to detect the transmission network in order to confirm the performance of the transmission network and locate transmission faults. The detection method can be physical layer detection or link layer / high layer packet detection. [0003] For example, between the base station controller (GBSC, GSM Base Station Controller) and the base station transceiver (GBTS, GSM Base Transceiver Station) in the Global System For Mobile Communication (GSM) through the E1 interface line transmission, When the quality of communication between GBSC and GBTS is degraded, even interrupted or unstable, the existing technology adopts an offline detection scheme based on detection instruments, such as figure 1 As shown, one side (eg GBSC side) is connected to ...

Problems solved by technology

[0007] Using this scheme for detection requires data packets to have a check digit, which requires high-level protocol support; for data packets without a check digit, this method cannot be used; At the same time, the high-level protocol needs to be processed by the service processor. If too many error detection functions are added, it may affect the service processing performance; if the link chip / physical layer (PHY, Physical Layer) chip in GBSC and GBTS does not correct the When an error is detected in the data packet, it is impossible to determine whether it is a service processor error, a link processing error or a transmission line error, which is not convenient for fault location
