Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described further.
This programme is referred to as incremental bi-plane systems upgrading scheme, and Fig. 2 and Fig. 3 have shown the node upgrading principle of this programme:
The compatibility of this escalation process requires to see the following form:
| Numbering | The compatible requirement of internal system |
| 1 | Maintenance Point compatible with maintenance on upgrading control interface main controlled node |
| 2 | The service delivery interface (message format and semanteme) of striding the plane keeps compatible |
| 3 | The resource control interface (message format and semanteme) of striding the plane keeps compatible |
| 4 | It is compatible that internal communication protocol using between the internal system node keeps |
In Fig. 2, the monoplane in left side refers to the old plane before the upgrading, redundant node by backup is downloaded new version software, this redundant node and Maintenance Point communicate, start the back and create a new plane for it by Maintenance Point, in follow-up picture and text, also useful legacy version plane and redaction plane are come the virtual plane of being made up of working cell, node before and after the upgrading is described, and its core concept is the same.
System uses the master control node of a redundancy and from Control Node, by the progressively upgrading of working cell, progressively finishes whole upgrade process, and main controlled node is upgraded at last.As shown in Figure 2, system at first uses the redundant master control node 0 of starting and upgrading and original master control node 1 to communicate the information interaction that keeps distribution of services and resource management.Progressively upgrade and be registered to new master control node 0 in all working unit of gradually former master control node 1 being controlled (each working cell has from Control Node and a plurality of resource node) then, as shown in Figure 3, and the master control node 1 of upgrading again at last.The process of each working cell upgrading is at first to allow redundant upgrade and the same logical resource from Control Node of configuration and working cell to be upgraded from Control Node, next is that locking is waited for from professional idle (the new business of not reallocating of Control Node from Control Node, but still the control of carrying out resource is removed up to the related resource node), treat from the Control Node business during free time, lock the resource node under it, wait for when these resource nodes are idle, upgrade these resource nodes and control its be registered to redundant upgraded from Control Node, new for the Control Node interrelated logic resource that comes into force automatically, upgrade at last this working cell from Control Node, enter next circulation.All finish from Control Node and resource node upgrading after, upgrading master control node, this master control node can be used as the backup of new Control Node and carries out work, upgrading is used also can to wait for next time.
Wherein, first just can provide professional processing from Control Node 0 upgrading back, with guarantee working cell that locking is next to be upgraded from Control Node the time, business can be distributed to it and handle, still by former from Control Node finished for the resource control of this working cell this moment.
If problem has appearred in system's certain node in the process of upgrading, equally can be under the situation of the non-interrupting service level and smooth rollback of system so, the course of work is the same, because the new and old edition plane is symmetrical fully, the mode that also can adopt the new and old edition plane to coexist is kept the normal operation of system.
In above-mentioned description, redundant master control node all is same address with redundancy before and after the Control Node upgrading, but in fact, redundant master control node with redundant from Control Node before not carrying out software download the redaction and renewal with legacy version in master control node to be upgraded and to be upgraded be the same from Control Node, function upgrading then after having carried out the software download in the redaction and having upgraded is called in following description and acts on behalf of master control node and agency from Control Node.On the other hand, before node to be upgraded in working face is registered to new plane, act on behalf of the master control node and the agency can duplicate master control node to be upgraded and the static configuration data on Control Node to be upgraded the old plane after Control Node starts, the process of switching is exactly the master control node to be upgraded in the synchronous old plane and the process of the dynamic configuration data on Control Node to be upgraded.
The system upgrade method that the embodiment of the invention one provides may further comprise the steps:
Step s110, act on behalf of the master control node and the agency creates a new plane from Control Node.
Step s120, describedly act on behalf of the master control node and the agency duplicates master control node to be upgraded and the static configuration data from Control Node to be upgraded the old plane from Control Node, with corresponding master control node to be upgraded in the described old plane with to be upgradedly transmit professional mutually and to manage resource mutual from Control Node.
In above-mentioned steps s110～s120, described act on behalf of master control node and agency from Control Node by the redundant master control node that backs up the described old plane and redundant download and upgrade the new version software upgrading from Control Node form, and described act on behalf of master control node and agency from the resource management of Control Node by the master control node to be upgraded on described old plane with to be upgradedly finish from Control Node.
Step s130, described master control node to be upgraded in described old plane of acting on behalf of switch dynamic configuration data after Control Node and resource node to be upgraded all are registered to described new plane, it is mutual to take over traffic assignments and resource that the master control node to be upgraded in the described old plane carries out in the described new plane; Upgrade then master control node to be upgraded in the described old plane.
In this step, to be upgraded in the described old plane all is registered to described new plane from Control Node and resource node to be upgraded and may further comprise the steps:
Step s131, the locking to be upgraded from Control Node.
Step s132, describedly to be upgradedly when idle, lock described resource node to be upgraded from Control Node control to be upgraded from Control Node.
Step s133, described resource node to be upgraded are during the free time, the described resource node to be upgraded of upgrading, and the resource node described to be upgraded after upgrading finished is registered to described agency in the new plane from Control Node, and described agency is from the Control Node logical resource that comes into force automatically.
Step s134, upgrading are described to be upgraded from Control Node, and upgrading finishes, be registered to act on behalf of the master control node, with as the next one agency from Control Node to be upgraded from Control Node.
In the foregoing description, professional distribution and resource are relatively independent alternately, and wherein the switching (or being called synchronously) of duplicating with dynamic configuration data of static data belongs to resource management, and the distribution of business promptly refers to select the link carried out etc.
The embodiment of the invention adopts biplanar mode that system is upgraded, be that to be upgraded in the described old plane all is registered to described new plane from Control Node and resource node to be upgraded and adopts the biplane mode to upgrade, comprise: described master control node to be upgraded, to be upgraded from Control Node, resource node to be upgraded place old plane and the described master control node, agency acted on behalf of from new plane that Control Node is created.Wherein said new plane and described old plane are symmetrical fully, specifically comprise:
It is compatible that the service delivery interface on described new plane and described old plane keeps;
It is compatible that the resource management interface on described new plane and described old plane keeps;
It is compatible that inter-node communication agreement in described new plane and the described old plane keeps.
And act on behalf of master control node and Maintenance Point in master control node in the described new plane and the described old plane keep compatible on the upgrading control interface.This Maintenance Point itself is irrelevant with professional interruption, and escalation process is independently to carry out, and certain effect of contraction is played on new plane and old plane, also can by signaling manipulation to node lock, switch, processing such as registration.
So-called compatibility promptly refers between new plane and the old plane, and energy mutual communication between the internal node in the plane, carries out the mutual and distribution of resource, in the escalation process of system, by locking, registration, switch, the incremental node to be upgraded of upgrading one by one reduces professional interruption as much as possible.Automatic rollback during acting on behalf of master control node and/or the node to be upgraded of agency from Control Node and/or described old plane and in escalation process, break down in the above-mentioned new plane, and normal carry out professional.
The system upgrade method that the embodiment of the invention two provides, in some system architecture, master control node to be upgraded in the described old plane and to be upgraded when Control Node is fused into a local Control Node, local Control Node of redundancy of described new plane backup escalates into the backup local Control Node in the escalation process in advance.May further comprise the steps:
Step s210, the local Control Node of agency are created a new plane.
Step s220, the local Control Node of described agency are duplicated the static configuration data of the local Control Node to be upgraded in the old plane, transmit business mutually and manage resource mutual with local Control Node to be upgraded in the described old plane.
In above-mentioned steps s210～s220, the local Control Node of described agency is downloaded by the redundant local Control Node that backs up in the described old plane and is upgraded the new version software upgrading and forms, and the resource management of the local Control Node of described agency is finished by the to be upgraded local Control Node on described old plane.
Switch dynamic configuration data after the resource node to be upgraded of the local Control Node of step s230, described agency in described old plane all is registered to described new plane, it is mutual to take over traffic assignments and resource that the to be upgraded local Control Node in the described old plane carries out in the described new plane; Upgrade then to be upgraded local Control Node in the described old plane.
In this step, the resource node to be upgraded in the described old plane all is registered to described new plane and may further comprise the steps:
Step s231, locking local Control Node to be upgraded.
Step s232, described local Control Node to be upgraded lock the resource node to be upgraded of described local Control Node control to be upgraded during the free time.
Step s233, described resource node to be upgraded are during the free time, the described resource node to be upgraded of upgrading, and the resource node described to be upgraded after upgrading finished is registered to the local Control Node of described agency in the new plane, the local Control Node of the described agency logical resource that comes into force automatically.
In like manner, present embodiment two all is to adopt biplanar mode that system is upgraded with embodiment one, repeats no more.In like manner, the automatic rollback when node to be upgraded in local Control Node of the agency in the described new plane and/or the described old plane breaks down in escalation process, the normal business of carrying out.。
Undoubtedly, this escalation process of system has well solved the smooth upgrade of system; Is present problem the function that how to realize that the node of system locks, reshuffles, starts? only the semanteme for physically these functions of node is unclear, therefore, need understand that the logic function of node could really realize these functions.This needs the logical model of system.Logical model such as Fig. 4 of general Telecommunication Network Element equipment:
Intercom system is relatively independent in logic functional module, finish the communication task between other logic modules, scheme requires intercom system effective in whole upgrade process, otherwise can't carry out intercommunication, therefore the upgrading of intercom system is subjected to certain constraint, promptly keeps the compatibility of communication protocol between the internal node.
Physical equipment is the least unit that system forms physical resource, and as the E1 interface of Node Board, dsp chip etc., physical equipment provides smallest object such as fault detection, the software download etc. of Operation and Maintenance by the Control Software encapsulation.
Physical resource is to form the basic configuration unit that system physical is realized, all is physical resource as Node Board, stube cable etc., and in this programme, node is a physical resource, also is the operand of escalation process.
Logical device is abstract to physical equipment of realizing by Control Software encapsulation, be the least unit of control system inside, operate in certain DSP as one and go up the encoding and decoding speech logical device that the encoding and decoding process software may provide 100 road 64K the physical equipment allocation manager.
The basic object that the Telecommunication Network Element device interior business realizing of logical resource need be managed, common logical device by a plurality of difference in functionalitys realizes that the establishment of logical resource is by disposing finishing of suitable logical device.Need through interface E1 equipment, inner exchanging equipment and encoding and decoding speech equipment etc. as the speech business carrying
Business Processing realizes by state machine, and by finishing professional processing with the Signalling exchange of terminal or other network elements, the result of signaling process is normally to the control of local resource.
Node is finished its details behavior that locks, reshuffles, starts function and is depended on the logic function module of its deployment (being the management of Business Processing, logical resource, logical device management) fully in the system upgrade process, and these functions need be distributed to these logic function modules and realize.Following form has shown the distribution condition of these functional requirements:
| Distribute explanation | Service Processing Module | The logical resource administration module | The logical device administration module |
| Locking | Transfer service is to other Service Processing Modules, and old professional the continuation handled | Except that waiting for that Resources allocation has discharged, stop all service and informing business processing modules | Except that waiting for that Resources allocation has discharged, stop all service and notification logic resource management modules |
| Reshuffle | The new plane that definite needs are registered to | New business processing module that definite needs are registered to or global resource administration module | Definite needs are registered to new logical resource administration module |
| Start | Pass through broadcast registration | Arrive new industry by broadcast registration | By broadcast registration to newly patrolling |
| To new plane | Affair processing module or global resource administration module | Collect resource management module |
Dispose top case difference to some extent on the internal control details for different module physics, following example is described according to these different situations respectively.
The embodiment of the invention three provides a kind of system upgrade method, embodiment one is applied in the concrete system architecture scene, system uses half to concentrate half point loose control mode when Control Node is physically separated (master control node with from) or centralized control when Control Node is physically unified (master control node with from) fully, there is a master control node and from the redundancy of Control Node, under the normal condition, the master control node can be realized with active/standby mode, can work with the N+1 backup mode from Control Node, under the upgrade case, they are as agent node work.As shown in Figure 5, in diagram, this agent node adopts redundant node to represent, in fact this agent node is redundant master control node before the upgrading, and as acting on behalf of the master control node, follow-up Fig. 6 to Fig. 8 also is same processing, repeats no more in the system upgrade process.
In present embodiment, the logical resource management is realized as global logic resource management and the control of local logical resource, and Business Processing is realized as traffic assignments and professional the execution.Global logic resource management and traffic assignments are deployed in the master control node, and local logical resource control and professional the execution are deployed in from Control Node.
Escalation process is described:
The upgrading of Maintenance Point is independently carried out, and traffic affecting does not carry out, maintenance interface compatibility between necessary maintenance and the master control node before and after the upgrading.
The upgrading of resource node has influence on corresponding logical resource control module, by getting in touch of lock event, registration process deletion or foundation and logical resource control module.
Have influence on corresponding global logic resource and service distribution module from the upgrading of Control Node, by getting in touch of lock event, registration process deletion or foundation and global logic resource control module and service distribution module.
The upgrading of master control node needs special processing, uses a kind of mechanism that is called compatible locum, principle as shown in Figure 6:
Master control node and whether redaction, be updated no matter from the interface of Control Node, because the master control node is the center, plural master control node can't independently be worked, therefore, adopt agency mechanism in the process of upgrading: the service distribution module in two planes can be transmitted professional distribution mutually by the signaling process of Maintenance Point and two plane compatibles; The master control node on redaction plane is transmitted to early version master control node processing to the association requests of resource management, and beginning isochronous resources configuration data.When other the node except that legacy version master control node all upgrade finish and join new plane after, had only the master control node in the legacy version plane, and this moment, this master control node in fact only was that redaction master control node is served (before this, this master control node was both transmitted business mutually with the master control node on redaction plane, manage the subordinate's on legacy version plane node to be upgraded again), can lock the master control node of legacy version this moment, legacy version Control Node notice redaction master control node switches to normal operating conditions, redaction master control node is finished the data that need synchronously, redaction master control node stop Agent Status, and autonomous the managing business of beginning distributes and the global resource management work.
Upgrading order principle is followed: master control node (agency)+from Control Node (agency)+working cell 1[resource node+from Control Node]+...+working cell n[resource node+from Control Node]+master control node (master)+Maintenance Point, n is the working cell number.
The embodiment of the invention four provides a kind of system upgrade method, in like manner, embodiment two is applied in the concrete system architecture scene, system uses full control mode of disperseing, can be understood as does not have the master control node, can be understood as by a plurality of local Control Node of physically disperseing to form the master control node yet.There is a redundant node at least in local Control Node (being original master and slave Control Node), and the resource node of each local Control Node and control thereof is formed a working cell.As shown in Figure 7:
In present embodiment, the logical resource management is realized as global logic resource management and the control of local logical resource, wherein the global logic resource management is made up of the resource interactive module of a lot of this locality again, Business Processing is realized as traffic assignments and professional the execution, and wherein traffic assignments is realized as the service interworking module of a lot of this locality.Global logic resource management and traffic assignments are deployed in local Control Node by through part, and local logical resource control and professional the execution are deployed on the local Control Node equally.
Escalation process is described:
The upgrading of Maintenance Point is independently carried out, and traffic affecting does not carry out, maintenance interface compatibility between necessary maintenance and the master control node before and after the upgrading.
The upgrading of resource node has influence on corresponding logical resource control module, by getting in touch of lock event, registration process deletion or foundation and logical resource control module.
If local Control Node needs upgrading, is progressively upgrade-system of unit according to the working cell so, escalation process needs special processing, uses a kind of mechanism that is called compatible locum, and principle as shown in Figure 8.
When upgrading during a working cell, the local Control Node of a redundancy has been upgraded and has been finished and started success, becomes a local Control Node of agency.In the redaction plane on this standby local Control Node the service interworking module can transmit professional distribution (according to certain algorithm) mutually with the local Control Node of the legacy version of this working cell; The local Control Node on redaction plane is transmitted to the local Control Node of early version to the association requests of resource management and handles, and beginning isochronous resources data.When the resource node of other except that local Control Node in the working cell all upgrade finish and join new plane after, legacy version has had only local Control Node in the plane, and this moment, this node only was the local Control Node service of redaction, can lock the local Control Node of the legacy version of this working cell this moment, the local Control Node of the local Control Node event notice of legacy version redaction is switched, redaction master control node is suspended operation and is upgraded all synchrodatas, stop Agent Status after data sync is finished, and autonomous the managing business of beginning distributes and global resource interworking.
Upgrading order principle is followed: local Control Node (agency)+working cell 1[resource node+local Control Node]+...+working cell n[resource node+local Control Node]+Maintenance Point, n is the working cell number.
The embodiment of the invention also provides a kind of system, as shown in Figure 9, comprise: act on behalf of master control node 100 and agency and (comprise master control node 300 to be upgraded from the new plane of Control Node 200 establishments and the old plane at node to be upgraded place, to be upgraded from Control Node 400, resource node 500 to be upgraded); Wherein,
