Description
Technical field
The present invention relates to the method for alarm synchronization between a kind of AM/BAM, belong to alarm management technical field in the telecommunication management network.
Background technology
In telecommunication management network (TMN) field, field of network management comprises five functional: 1, configuration management; 2, alarm management; 3, performance management; 4, safety management; 5, accounting management.At present standard communications protocol commonly used is divided into two kinds of Simple Network Management Protocol (Simple NetworkManagement Protocol:Snmp) and CMIPs (Common ManagementInformation Protocol:CMIP) in the network management system, especially Snmp agreement, short with its construction cycle, agreement realizes simple advantage, has become the de facto standard agreement of network management gradually.
The Snmp protocol network managing system adopts the Manager/Agent framework, and wherein background net management is as Manager, and the foreground network element is as Agent, and background net management and foreground network element adopt the Snmp agreement to communicate.Each foreground network element all has an independent IP address, sends and receive Snmp message with User Datagram Protoco (UDP) (User DatagramProtocol:UDP) host-host protocol.The foreground network element sends network element alarming or alarm recovery message to background net management by the Trap message that defines in the Snmp agreement, after background net management receives Trap message, after the binding parameters such as the Alarm Sequence Number that parsing wherein comprises, alarm type, this alarm is recorded in the alarm pond on backstage and instant playback in the current alarm list interface, the O﹠M personnel can bring in the running status of monitoring foreground network element by the client of background net management system.But because UDP message is connectionless, it is unreliable transmission, and do not shake hands and acknowledge message between the AM/BAM, the foreground network element only is responsible for Trap is sent to background net management, but and do not know whether background net management receives Trap message, background net management is the Trap message that send on passive reception foreground, therefore under the situation of network environment more complicated, sometimes the alarm information that can occur between the AM/BAM is asynchronous, but for the network maintenance staff, it is very important synchronously that the alarm between the AM/BAM webmaster keeps.
For example:,, on background net management, just can't see this alarm like this because the complicated network structure has been lost once in a while if certain bar alarm information is in sending to the background net management process.Equally, if certain bar alarm recovery message has been lost in process of transmitting, corresponding alarm just can not recover always on the background net management platform so.
Problem for the alarm synchronization that solves AM/BAM, Chinese patent publication number 1486018, the invention and created name that open day is on March 31st, 2004 is " a kind of alarm consistency relatively reaches restoration methods ", disclose and a kind ofly effectively the activity fault warning information of webmaster side and network element side has been kept consistent method, this method is achieved in that (1) webmaster obtains all current active fault warning information of network element side from network element, compares one by one with all activity fault warning information of itself storing; (2) will change the recovery warning information into the state of all inconsistent webmaster side of all current active fault warning information of network element side current active fault warning information, on webmaster, recover corresponding activity fault warning.Though this method has realized the unanimity of AM/BAM alarm, but background net management need arrive the foreground and obtain all alarms, compares which alarm then in this locality and loses, and which alarm clearing is lost, thereby the background net management amount of calculation is bigger, and the Trap message total amount between AM/BAM is also excessive.
Summary of the invention
The technical problem to be solved in the present invention is the method for the AM/BAM alarm synchronization of a kind of Snmp protocol network managing system of proposing at the present situation of above-mentioned prior art, this method makes the background net management amount of calculation reduce, Trap message total amount between AM/BAM also reduces, and guarantees AM/BAM warning information unanimity.
The present invention adopts following technical scheme to realize:
(1) background net management obtains the unique identification of the current active alarm of wanting synchronous foreground network element in this locality, is organized into alarm synchronization message and sends to corresponding foreground network element;
(2) the foreground network element receives described alarm synchronization message, obtain comprising alarm identifier, and and the alarm identifier of the current active alarm of network element this locality, foreground relatively;
(3) if one or more signs of this foreground network element current active alarm not in the alarm identifier that the background net management that described foreground network element obtains sends, then send the corresponding alarm information of these signs to background net management, if the one or more alarm identifiers that do not exist the background net management of acquisition to send in the alarm identifier of foreground network element current active alarm promptly send the corresponding alarm recovery message of these signs to background net management.
Described alarm synchronization message is the form that is organized into the Simple Network Management Protocol bag.
Compared with prior art, adopt method of the present invention can reduce the amount of calculation of background net management, reduce the Trap message total amount between the AM/BAM, guarantee that the AM/BAM alarm is consistent, be convenient to the network O﹠M personnel and obtain network operation state timely and accurately.

Embodiment
Be that an embodiment is further introduced the present invention with broadband wireless access (BWA) system below, but not as a limitation of the invention.
BWA (BWA) is the broadband access means that telecom operators provide two-forty, big capacity, high reliability, full duplex with the signal load mode of point-to-multipoint, has realized the broadband wireless access of user terminal to backbone network.The BWA network management system is a subsystem of BWA system.In the present embodiment, the BWA network management system is the standard client/server configuration, background data base adopts Microsoft SQL Server, the Operation and Maintenance personnel use graphic user interface (GUI) terminal by BWA NM server visit SQL Server database, pass through the Snmp protocol communication between NM server and the network element system.
The general frame with reference to AM/BAM alarm management shown in Figure 1, in embodiments of the present invention, the warning information of background net management all leaves in the alarm pond, backstage, and background net management has started an alarm receiver specially, by alarm information or the alarm recovery message of its reception from the foreground network element, these message are handled, obtain an alarm object or alarm clearing object, and then in alarm pond, backstage, increase an alarm according to the interface that alarm pond in backstage provides, it is in full accord with the flow process that receives alarm of being sent by the foreground network element in the processing synchronizing process or alarm recovery message that the perhaps identical alarm of deletion from backstage alarm pond, this alarm receiver receive the flow process of handling the alarm that normally reported by the foreground network element or alarm recovery message.
With reference to shown in Figure 2, in order to satisfy the coherence request of AM/BAM alarm, the BWA network management system adopts following steps usually:
Step 101: background net management starts a plurality of alarm synchronization threads, is responsible for the alarm synchronization function of part foreground network element respectively, and the purpose that starts a plurality of threads is in order to improve treatment effeciency and to reduce timing length, and timed sending can guarantee that synch command automatically performs;
Step 102: this thread of interface accessing that each alarm synchronization thread provides by alarm pond, backstage is responsible for the Alarm Sequence Number of all movable alarms of synchronous foreground network element, and the Alarm Sequence Number that obtains is formed Snmp Set according to the form of consulting wrap, according to interface management database (MIB) file of AM/BAM, issue alarm synchronization message to corresponding foreground network element;
The step that the Alarm Sequence Number that obtains is formed Snmp Set bag according to the form of consulting is:
(a1) byte arrays of definition, its length is: 2 * (alarm sum+1), and two of this byte arrays fronts are defined as the alarm sum;
(b1) each Alarm Sequence Number that obtains from backstage alarm pond is converted to 2 bytes (for example being converted to upper byte with 257 is 1, and low byte also is 1), be connected on the byte or the double byte after the previous conversion of alarm sum after;
(c1) repeat (b1) cyclic transformation Alarm Sequence Number one by one, to all converting;
(d1) this byte arrays is converted to character string type.
Step 103: after the foreground network element is received the alarm synchronization message of sending on the backstage, resolve all Alarm Sequence Number that wherein comprise according to the message format of consulting;
Resolving is:
(a2) convert the character string in the alarm synchronization message that receives to byte arrays;
(b2) all Alarm Sequence Number are obtained in circulation one by one;
Step 104: the Alarm Sequence Number tabulation that the foreground network element is tabulated the Alarm Sequence Number that obtains and foreground network element current active is alarmed in the pond compares, if there is not certain serial number in the network element current active alarm pond, foreground in the Alarm Sequence Number that the foreground network element obtains, then send corresponding alarm information to background net management, if the Alarm Sequence Number that does not exist the foreground network element to obtain in the foreground network element current active alarm pond promptly sends corresponding alarm recovery message to background net management.
This step realizes by two sub-steps that adopt following ectonexine nested loop structure:
(a3) setting outer circulation variable is the Alarm Sequence Number in the network element current alarm pond, foreground, and interior cyclic variable is the Alarm Sequence Number that background net management sends; In outer circulation, obtain the Alarm Sequence Number in certain network element alarming pond, bar foreground successively, in interior circulation, if in the Alarm Sequence Number in this network element current alarm pond, foreground and the backstage Alarm Sequence Number is identical, then these two Alarm Sequence Number are deleted from tabulation separately and (in follow-up circulation, just do not had the variables corresponding value, to reduce the cycle-index of back, thereby improve the processing speed of foreground network element), and withdraw from interior circulation, again next bar alarm is handled in outer circulation; If do not find identical Alarm Sequence Number, the foreground network element is sent out the alarm information of this foreground Alarm Sequence Number of correspondence to background net management so.
(b3) setting the outer circulation variable is the Alarm Sequence Number that background net management sends, and interior cyclic variable is the Alarm Sequence Number in the network element current alarm pond, foreground; In outer circulation, obtain the Alarm Sequence Number that a backstage sends, in interior circulation, if in the Alarm Sequence Number in this backstage Alarm Sequence Number and the network element current alarm pond, foreground is identical, then these two Alarm Sequence Number are deleted from tabulation separately, and withdraw from interior circulation, again next bar alarm is handled in outer circulation; If do not find identical Alarm Sequence Number, so the foreground network element send out one to alarm recovery message that should the backstage Alarm Sequence Number to background net management.
In the present embodiment, the foreground network element can also by different bound values distinguish alarm information and alarm recovery message be normally report or alarm synchronization message, accept situation thereby can make things convenient for the user to understand ALM.
