A communication status detection method for boards in communication system

Abstract

The invention provides a method for detecting inter-board communication state, which includes regularly analyzing the communication state of a single board by a main control board in a detection period and determining that the single-board communication state is normal if a single-board confirmation information of a communication detection pack, that adding the number of times that the confirmation information of the communication detection pack is not received, determining the single-board communication state depending on whether the number of times reaches a set upper limit value and determining that the single-board communication state is normal if the upper limit value is reached; and continuously sending the communication detection pack to the single board if the confirmation information of the communication detection pack is not received and the number of the non-response times does not reach the set upper limit value. The invention can reliably and accurately detect the communication state between a main control board and a task single board to obviate detection function failure that might exists due to hardware implementation and communication failure resulting from abnormal single-board communication module in prior art.

Description

technical field [0001] The invention relates to a method for detecting the communication state between a main control board of a communication system equipment and a service single board, and the method provides a mechanism for detecting the communication state between the boards. Background technique [0002] In the communication system equipment, the general background management system transfers information to the service board through the main control board, and the management and monitoring of the service board all depend on the communication between the main control board and the single board. Whether the communication channel is normal. If the communication channel is abnormal, the background management system will lose the management and monitoring of the service board, which may cause service interruption or abnormality of the entire system. [0003] At present, the detection of the communication status of the single board is mostly realized by adding the detection...

But the disadvantages are also obvious: (1) The premise of whether this function can work normally is that the detection line of the backup board is valid. It indicates that the communication of the single board is normal, that is, when the detection line of the standby board detects that the communication is normal, the communication module of the service single board may be abnormal and the communication between the main control board and the service board may not be smooth.
