Yet, in the existing systems upgrade technique, be to reset by total system to restart mode or " on-line loaded+total system resets and restarts mode " realization basically.Because they have all used to reset and have restarted, so must cause the interruption fully of system business.Although when adopting " on-line loaded+total system resets and restarts mode ", because need not break in service during on-line loaded, thereby having reduced break period, this still can't satisfy the requirement of high reliability communication system.
In actual applications, there is following problem in such scheme: in the communication system upgrading process, can't avoid the service disconnection of system level, destroy the continuity and the consistency of system service, thereby reduce the reliability of this communication system.
Cause the main cause of this situation to be, communication system does not adopt the design framework of dual systems, and the mode of system upgrade still rests on the mode that resets and restart.
In order to address the above problem, the thought of dual systems upgrading is suggested.So-called dual systems is exactly on an original system-based, a back-up system is set again supports, and its intension is: when old system extinction time, new system is parallel to be inserted.Use dual systems; can effectively reduce system risk; real-time, integrality, the consistency of system data and service have been guaranteed to greatest extent; and under the situation of system maintenance and upgrading; can provide and not shut down environment; guarantee professional continuity, avoided the various losses that bring because of the system break operation.These features just a high reliability communication system should possess, yet present dual systems still rests on the agreement the abstract definition of noun, does not propose practicable design.The present invention has remedied the blank in this actual design zone to a certain extent.

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.
Realize a communication system, must design an outstanding system framework, to organize and to carry out the method for various assurance reliabilities with high reliability.As the entity of realizing the aftermentioned smooth upgrading method, the present invention illustrates a Communication System Design framework earlier, and this design framework not only can satisfy the requirement of common communication system Frame Design, two logic system upgrade methods that can also provide.As shown in Figure 1, the Communication System Design framework among the present invention is made up of System Control Center 10, service process subsystem 20, switching subsystem 30, interface subsystem 40 and exchange and interface resource control centre 50.
System Control Center 10 is used for unified control whole system.It has adopted active and standby plate Redundancy Design, when system upgrade, the slave board of System Control Center 10 can independently become the logic control center of a new system, that is to say that this moment, System Control Center 10 can be seen two control centres in logic as: by first logic system control centre of mainboard realization and the second logic system control centre that realizes by slave board.The former is used for old system, and the latter is used for new system.
Switching subsystem 30 is used to provide switching plane,, use for internal system communication, for example traditional switch, asynchronous transfer mode (Asynchronous Transfer Mode is called for short " ATM ") switch, router etc. all belong to wherein a kind of.In addition, what deserves to be explained is that clock system also can be based on switching subsystem 30.
The interface that provides whole communication system external is provided interface subsystem 40, as Ethernet interface, RS232 interface etc.
Exchange is used to control switching subsystem 30 and interface subsystem 40 with interface resource control centre 50.
In the Communication System Design framework, the connection control relation of above-mentioned 5 modules is as follows: System Control Center 10 connects each business unit and exchange and the interface resource control centre 50 that is controlling in the service process subsystem 20; Exchange is connected again with interface resource control centre 50 is controlling switching subsystem 30 and interface subsystem 40.In general, in above-mentioned Communication System Design framework, the design of switching subsystem 30 and interface subsystem 40 is publicization, does not have the upgrading requirement substantially; Upgrading generally is at service process subsystem 20 and System Control Center 10 two parts, for example code upgrade, data configuration upgrading, the change of each several part interface etc.
Following surface analysis Communication System Design framework proposed by the invention can be applied to the principle of smooth upgrade.
Generally speaking, in escalation process, present design framework remains a cover communication system physically, just when the upgrading beginning, slave board is independently become a new System Control Center in logic, make System Control Center 10 be divided into the first logic system control centre and the second logic system control centre, utilize the level and smooth extinction of old system and smoothly enabling of new system then, realize smooth upgrade.After upgrading finished, as mainboard, and the first logic system control centre of original system degradation became slave board with the second logic system control centre of new system.This makes that under the situation of not upgrading communication system still is a cover, does not produce the material redundancy.
As indicated above, because switching subsystem 30 and interface subsystem 40 are publicization parts, thereby there is no the upgrading requirement.Yet, the fixing external physical interface that they provided is the physical connection restriction of smooth upgrade, what therefore the present invention adopted is the upgrading mode of sharing interface subsystem 40, at first under the prerequisite that keeps original physical connection, by increasing the link and the route of interface, share and use original physical to connect, make new-old system to obtain information, seamlessly transit from physical interface.
And System Control Center 10 in the design framework and service process subsystem 20 need independent operation in escalation process.Under the control of the first logic system control centre, old system gradually reduces traffic carrying capacity; Under the control of the second logic system control centre, new system progressively increases traffic carrying capacity.This be one by one business unit from the deletion of old system dynamics, increase process in new system dynamics, code, data structure, the interface of System Control Center 10 and service process subsystem 20 can be independent fully before and after the upgrading, unfettered, this is suitable for upgrade application widely.
Said process is the process of a dual systems control, and this depends on managing independently of exchange and interface resource control centre 50.As long as exchange can be managed switching subsystem 30 and interface subsystem 40 independently with interface resource control centre 50, accept the control of dual systems and can accomplish, be whose control because it can not remembered, only need to carry out.And on the other hand, system mainly realizes by system's active inquiry when obtaining maintenance information; Can report two control system entirely as for information such as alarms.
Utilize the logic dual system to carry out the method for smooth upgrade below in conjunction with the above-mentioned design framework of accompanying drawing 2 explanations:
At first enter step 101, communication system is utilized the active and standby plate Redundancy Design of System Control Center 10, logically is divided into new and old two systems.Specifically, promptly when system upgrade, the slave board of System Control Center 10 independently becomes the second logic system control centre of a new system, with the first logic system control centre of the old system of mainboard, constitutes dual systems.
Then enter step 102, new system increases new link or route, shares exchange, interface resource with old system.As mentioned above, the realization of this step depends on sharing of interface subsystem 40 and managing independently of exchange and interface resource control centre 50.
Enter step 103 then, old system dynamics is deleted certain business unit, and new subsequently system dynamically increases this business unit immediately.A business function comprises a plurality of business unit, when upgrading, can wait until that an old service end in the business unit later on just at this business unit of old system-kill, can not cause the loss of any function like this; If waits for too long even still be untreated old service, also can dynamically be deleted this business unit, can cause the partial loss on the business function this moment, but can not cause system-level service disruption.
Then enter step 104, judge whether whole business unit have switched to new system.If then enter step 105, otherwise return step 103.
In step 105, the slave board of old system upgrades to the mainboard of new system, and the mainboard of old system is downgraded to the slave board of new system, then deletes the link or the route of old system, thereby finishes the upgrading of system.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those skilled 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.
