Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] see image 3 As shown, the embodiment of the present invention provides a method for transmitting alarm information between disks in an IPRAN device, comprising the following steps:

[0020] The main control panel sends polling frames, starting from line panel No. 1 to line panel n in turn, where n is a positive integer greater than 1, and each line panel sends a response at the beginning of the next frame when it is called according to the polling command Frame, after the main control panel polls once, all the alarm information collected, including the local alarm information of the main control panel, will be broadcast to the For all circuit boards, see Figure 4 As shown, the custom HDLC protocol frame includes broadcast address, control word, calling address, data and FCS (Frame Check Sequence, frame check field), and the...

Abstract

The invention discloses a transmission method and system of inter-panel alarm information in IPRAN equipment, and relates to the field of IPRAN. The method comprises the steps that a master control panel sends out a poll frame, each circuit panel sends a response frame from the net frame when the corresponding circuit panel is called according to a poll command, when polling is conducted by the master control panel once, all the collected alarm information is broadcasted to all the circuit panels in a mode of a user-defined HDLC protocol frame, the user-defined HDLC protocol frame comprises a broadcast address, a control word, a calling address, data and a frame verifying field, the frame head and the frame tail are automatically recognized through signs, and the number and the lengths of the frames are changed by modifying parameters of a control portion. All the circuit panels receive information of the broadcasted user-defined HDLC protocol frame, and mutual transmission of all the inter-panel alarm information in a system is achieved. Under the precondition that hardware is not changed, free increase and decrease of the amount of the alarm information can be achieved, transmission is reliable, and test requirements of various operators are met.

Description

technical field [0001] The present invention relates to the field of IPRAN (IP Radio Access Network Carrier, IP-based wireless backhaul bearer network), in particular to a method and system for transmitting alarm information between disks in IPRAN equipment. Background technique [0002] Among various devices in the optical network, the transmission of alarm information between disks is indispensable. In IPRAN equipment, there is a large amount of alarm information that needs to be transmitted between disks, ranging from thousands to tens of thousands, and the number of alarm information that needs to be configured for different devices is also different, sometimes according to the needs of operators. Adjust the number of warning messages. In the past, the transmission method of equipment alarm information is generally: using the system clock signal SFP (SDH Frame Pulse, SDH frame indication pulse) synchronized with SDH (Synchronous Digital Hierarchy, synchronous digital se...
