Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is mainly used in the professional upgrading of the system of demand of not interrupting.In this type systematic, the intelligence part of system all is to use Embedded veneer usually, so data and software all are stored on the veneer.Concrete example is exactly that the present invention can be used for upgrading in each device software of communication system.
In order to realize method of the present invention, need the veneer in the system be provided with, and increase controller.As shown in Figure 1.The memory block of veneer is divided into the master and uses the memory block, i.e. primary area, and spare memory area promptly is equipped with the district.In addition, controller is used for carrying out the operation that switch in active and standby district by the Systems Operator.
Controller can be realized by the software that system management platform increases corresponding function.Controller needs the interface that is connected to veneer, by this interface, the operator can send the order of switching the primary area and being equipped with the district to veneer, can realize by the mode of adjusting pointer with the switching that is equipped with the district in the primary area in the veneer, be the start pointer that has the primary area in the controller and be equipped with the district, when needs switched active and standby district, the definite object memory block that only needs initially to make a comment or criticism got final product, from here as can be seen, it is a lot of to have switched the simplified control that covers original software in the operation in active and standby district and the prior art.
In addition, the primary area in the veneer is distinguished and can be exchanged with being equipped with, but at any time, all has only a district to be used for professional operation.Usually, the district that is used to move is called as the primary area, and the district that is not activated is called as and is equipped with the district.
Below in conjunction with accompanying drawing 2, specify concrete enforcement of the present invention.
In step 100, when system need upgrade, the Systems Operator sent order by controller to veneer, and new software and data load are distinguished to being equipped with.In the process of distinguishing loading data and software fully, primary area operate as normal, business do not need to interrupt, and make like this at loading duration total system not to be had any impact.For example in communication system, equipment such as RNC, NodeB, media gateway are when using prior art to upgrade, because these equipment are generally at far-end, the problem of service disconnection can compare significantly, promptly in the escalation process, loading the new software time relatively can be long, therefore have the service disconnection of long period, and if the upgrade method among use the present invention, because new software is in loading procedure, system does not need interrupting service, therefore the upgrading influence that operation brings to system can be reduced to minimum.For the communication facilities of other types, comprise that the upgrading of the communication facilities, optical communication equipment etc. of fixed network can be used method of the present invention.
Then enter step 110, behind the loaded, the Systems Operator issues to veneer by controller switches the order of active and standby district, and activates new primary area software.In the process of switching, system business carries out of short duration interruption.If will switch active and standby district, the Systems Operator need be interrupted the program in original primary area by controller, adjust then program pointer to the corresponding place in new primary area to activate new primary area software, with system restart, all reinitialize, and at this moment system can bring into use new upgrading software and data to carry out work.In the process of switching active and standby district, the dynamic data of previous system operation is all lost, for example for communication system, ongoing conversation all can be interrupted when carrying out the switching of active and standby district, some information of those interrupted conversations are dropped, can the operation of new software not impacted, because these dynamic datas do not need to keep.And the data that new primary area needs are some configuration datas that loaded, and belong to static data, can normally commence business in therefore new primary area.
In step 120, whether the operator needs attention location system in the process of trial run, can normally move.If can normally move, then enter step 130.Otherwise enter step 140.Therefore new upgrading software need try out because stability and various aspects of performance are also uncertain.In the trial run process, being equipped with in the district after the switching kept original software and versions of data, and the primary area is different with the content that is equipped with the district.At this moment being equipped with the district is used for can reruning original early version software in case upgrade when failing.
In step 130, owing to judged that in step 120 system can normally move between trial run period, so the Systems Operator can will distinguish with the primary area synchronous at reasonable time fully.At this moment being equipped with the district can be as a backup in primary area, can be used for taking place in the primary area some when unusual, is directly switch to be equipped with the district and to carry out service operation.The time of trial run decides according to concrete system.After having tested the various performances of new software,, then can judge and upgrade successfully if new version software all can normally move.At this moment can send synchronous active and standby district order by controller by the Systems Operator.After active and standby district was synchronous, the content that is equipped with the district was identical with the primary area.Synchronous active and standby district does not have any impact to the normal operation of system.Being equipped with the district can be as the backup of system software and data, be used for when system's operational process contingency is damaged, can directly enabling backup software and data in the software and the data in primary area, cause damage avoiding, make when contingency primary area data or software damage simultaneously, system business minimizing break period, the influence that can cause the regular traffic operation of system reduces to minimum.
In step 140, owing to judge new upgrading software cisco unity malfunction in trial run in step 120, so the Systems Operator need pass through controller, switches active and standby district once more, return back to again in original software and the data and reruns.The method of switching active and standby district is identical with step 110.In the present invention, when system upgrade is failed, no longer need the time to reload original software,, therefore only need spend the time of switching active and standby district because original software in being equipped with the district, does not have deleted or covers, get final product so that system recovery to normal operating condition.And in the prior art, if the upgrading failure then needs system business is interrupted, reload original software then, therefore, usually when utilizing prior art to upgrade, need return back to original software when being used for upgrading failure for just in case certain hour is reserved in the upgrading failure.Therefore as can be seen, use upgrade method of the present invention, significantly reduced system's rollback and returned the required consumed time of original software, therefore significantly reduced because the time that the software upgrading failure is interrupted system business.Software upgrading is further reduced the influence of system.
Adopt the method in active and standby district to carry out software upgrading and also have an advantage, promptly in escalation process, various configuration informations that can saved system, these configuration informations are very important to the normal operation of system, if new software arrangements is made mistakes, cause system normally to move possibly.Even when using prior art to come system software upgraded, also need to come the configuration information of standby system by certain mode, but, might go out the situation of some important informations of active owing to might not be with original software and data full backup in the prior art.And use method of the present invention owing to do not delete or cover original software and data, therefore complete reservation all configuration informations, further guaranteed the reliability and the security of system software upgrading.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
