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
The present invention relates to IPRAN(IP Radio Access Network Carrier, IPization wireless backhaul bearer network) field, particularly relate to transmission method and the system of warning information between the mid-game of a kind of IPRAN equipment.
Background technology
In the various device of optical-fiber network, between dish, the transmission of warning information is indispensable.In IPRAN equipment, there is a large amount of warning information between dish, mutually to transmit, thousands of at least, up to ten thousand at most, and also the quantity of the warning information that need to join of distinct device is also different, sometimes also will adjust according to the demand of operator the quantity of warning information.The transmission method of equipment alarm information was generally in the past: adopt and SDH(Synchronous Digital Hierarchy, synchronous digital hierarchy) the clock signal of system SFP(SDH Frame Pulse of frame synchronization, the marker pulse of SDH frame) location, SFP is that speed is the pulse that 8000HZ, duty ratio are 1/3125, be used to refer to SDH frame frame head, alarm speed is generally 1～25MHz, every kind of warning information takies a hardware line, the business dish of different slots position takies different time-gap, shown in Figure 1.The speed of the transmission method of this warning information is low, time slot allocation easily, transmit reliable and stable, still, the transferable warning information limited amount of every frame, even if clock rate is brought up to 25MHZ, each SFP clock cycle can pass 3125bit at most.
Along with PTN(Packet Transport Network, Packet Transport Network) in the exploitation ， operator test process of equipment, office side requires every circuit dish alarm entry number can reach 4K*3bit at most.Complete so transmission of multitooth alarming information, must find new solution.Conventionally there are two kinds of ways, or increase hardware line, or improve clock rate.If increase hardware line, will carry out correcting to single-deck hardware, workload is large, and the time also has little time, and will increase the line of a lot of roots and backboard terminal, infeasible; If raising clock rate, will bring up to 350MHZ above, the too high reliability that is unfavorable for transmission of speed, and require very harsh to clock phase.Therefore must get rid of these two kinds of conventional solutions, seek additive method and solve.
It is not very high that the system of considering required the whole transmission time, can adopt multi-frame structure, shown in Figure 2, by a plurality of SFP cycle, complete the transmission of a warning information, each SFP cycle is a single frames, frame head comprises corresponding groove position information and sign, so just can, by adjusting the quantity of single frames in multi-frame, realize flexibly the transmission of warning information in enormous quantities.Along with the development of IPRAN equipment, multi-frame quantity is more and more, and multi-frame structure relies on the synchronous implementation of system SFP framing completely, seems unable to do what one wishes, cannot meet the growing test request of each operator.
