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 | Service delivery interface (message format and semanteme) across plane keeps compatible |
| 3 | Resource control interface (message format and semanteme) across plane keeps compatible |
| 4 | It is compatible that internal communication protocol using between internal system node keeps |
In Fig. 2, the monoplane in left side refers to the old plane before upgrading, redundant node by backup is downloaded new version software, this redundant node and Maintenance Point communicate, after startup, by Maintenance Point, be that it creates a new plane, in follow-up picture and text, also useful legacy version plane and redaction plane are described the virtual plane being comprised of working cell, node before and after upgrading, and its core concept is the same.
System uses the master control node of a redundancy and from controlling node, the progressively upgrading by working cell, progressively completes whole escalation process, and main controlled node is finally upgraded.As shown in Figure 2, first system uses the redundancy master control node 0 of starting and upgrading to communicate with original master control node 1 information interaction that keeps distribution of services and resource management.Then 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 controlling node and a plurality of resource node), as shown in Figure 3, and the master control node 1 of finally upgrading again.The process of each working cell upgrading be first allow redundancy from controlling that node is upgraded and the same logical resource from control node of configuration and working cell to be upgraded, next is that locking is waited for from controlling idle (the new business of not reallocating of node traffic from controlling node, but still carry out resource control until related resource node remove), when idle from control node traffic, lock the resource node under it, wait for when these resource nodes are idle, upgrade these resource nodes and control its be registered to redundancy upgraded from controlling node, new for controlling the node interrelated logic resource that automatically comes into force, finally upgrade this working cell from controlling node, enter next circulation.All from controlling node and resource node and upgrade, upgrading master control node, this master control node can be used as the backup of new control node and carries out work, also can wait for upgrading use next time.
Wherein, first just can provide the processing of business from controlling node 0 upgrading, with guarantee working cell that locking is next to be upgraded when controlling node, business can be distributed to it and process, now for the resource of this working cell, control or by former, from controlling node, completed.
If there is problem in system certain node in the process of upgrading, equally can be the in the situation that of the non-interrupting service level and smooth rollback of system so, the course of work is the same, because new and old edition plane is symmetrical completely, the mode that also can adopt new and old edition plane to coexist maintains the normal operation of system.
In above-mentioned description, redundancy master control node and redundancy are all same address from controlling node upgrading front and back, but in fact, redundancy master control node and redundancy from control node do not carry out software redaction download and upgrade before with legacy version in master control node to be upgraded and to be upgraded from controlling node, be the same, carried out software in redaction download and upgrade after function upgrading, in following description, be called and act on behalf of master control node and agency from controlling node.On the other hand, node to be upgraded in working face is registered to before new plane, act on behalf of master control node and agency and can copy master control node to be upgraded and to be upgraded from controlling the static configuration data node in old plane from controlling node starts, the process of switching is exactly master control node to be upgraded in synchronous old plane and to be upgraded from controlling the process of the dynamic configuration data node.
The method for upgrading system that the embodiment of the present invention one provides, comprises the following steps:
Step s110, act on behalf of master control node and agency creates a new plane from controlling node.
Step s120, describedly act on behalf of master control node and agency and copy master control node to be upgraded old plane and to be upgraded from controlling the static configuration data of node from controlling node, with corresponding master control node to be upgraded in described old plane and to be upgraded mutual from controlling the mutual forwarding service of node and managing resource.
In above-mentioned steps s110～s120, describedly act on behalf of master control node and agency and form from controlling node and downloading and upgrade new version software upgrading from the redundancy master control node controlling node and back up in described old plane and redundancy, and describedly act on behalf of master control node and agency from the resource management of controlling node by the master control node to be upgraded of described old plane with to be upgradedly complete from control node.
Step s130, described to be upgraded in described old plane of master control node of acting on behalf of switch dynamic configuration data from controlling node and resource node to be upgraded are all registered to described new plane, take over traffic assignments and resource that the master control node to be upgraded in described old plane carries out in described new plane mutual; The master control node to be upgraded of then upgrading in described old plane.
In this step, to be upgraded in described old plane is all registered to described new plane and comprises the following steps from controlling node and resource node to be upgraded:
Step s131, lock to be upgraded from controlling node.
Step s132, described to be upgraded from controlling node during the free time, locks described to be upgraded from controlling the resource node to be upgraded of node control.
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 is completed is registered to described agency in new plane from controlling node, described agency is from controlling the node logical resource that automatically comes into force.
Step s134, described to be upgradedly upgrade complete from controlling node of upgrading, be registered to and act on behalf of master control node, usings as next to be upgraded from the agency who controls node from control node.
In the foregoing description, the distribution of business and resource are relatively independent alternately, and wherein copying with the switching (or being called synchronous) of dynamic configuration data of static data belongs to resource management, and the distribution of business refers to the link that selection is carried out etc.
The embodiment of the present invention adopts biplanar mode to upgrade to system, be that to be upgraded in described old plane is all registered to described new plane and adopts biplane mode to upgrade from controlling node and resource node to be upgraded, comprise: described master control node to be upgraded, to be upgraded from controlling the old plane at node, resource node to be upgraded place and describedly acting on behalf of the new plane that master control node, agency create from controlling node.Wherein said new plane and described old plane are full symmetrics, specifically comprise:
It is compatible that the service delivery interface of described new plane and described old plane keeps;
It is compatible that the resource management interface of described new plane and described old plane keeps;
It is compatible that inter-node communication agreement in described new plane and described old plane keeps.
And act on behalf of master control node and Maintenance Point in the master control node in described new plane and described old plane keep compatible on upgrading control interface.The interruption of this Maintenance Point itself and business is irrelevant, and escalation process is independently to carry out, and new plane and old plane are played to certain effect of contraction, also can by signaling manipulation to node lock, switch, the processing such as registration.
So-called compatibility refer between new plane and old plane, and can communicate by letter mutually between the internal node in 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 the interruption of business as much as possible.Automatic rollback during acting on behalf of master control node and/or agency and break down in escalation process from controlling node to be upgraded node and/or described old plane in above-mentioned new plane, and normally carry out business.
The method for upgrading system that the embodiment of the present invention two provides, in some system architecture, master control node to be upgraded in described old plane and to be upgraded from control node be fused into one local while controlling node, redundancy of described new plane backup is local to be controlled the backup local that node escalates in escalation process in advance and controls node.Comprise the following steps:
Step s210, the local node of controlling of agency create a new plane.
Step s220, the local node of controlling of described agency copy the to be upgraded local static configuration data of controlling node in old plane, control the mutual forwarding service of node and manage resource mutual with this locality to be upgraded in described old plane.
In above-mentioned steps s210～s220, described agency is local to be controlled the local node of controlling of redundancy that node backs up in described old plane and downloads and upgrade new version software upgrading and form, and the local resource management of controlling node of described agency is completed by the to be upgraded local control node of described old plane.
The local control after the resource node to be upgraded of node in described old plane is all registered to described new plane of step s230, described agency switched dynamic configuration data, and taking over to be upgraded local in described old plane, to control traffic assignments and resource that node carries out in described new plane mutual; The to be upgraded local node of controlling of then upgrading in described old plane.
In this step, the resource node to be upgraded in described old plane is all registered to described new plane and comprises the following steps:
Step s231, lock the local node of controlling to be upgraded.
Step s232, the described local node of controlling to be upgraded, during the free time, lock the described local resource node to be upgraded of controlling node control to be upgraded.
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 is completed is registered to the local node of controlling of described agency in new plane, described agency is local controls the node logical resource that automatically comes into force.
In like manner, the present embodiment two is all to adopt biplanar mode to upgrade to system with embodiment mono-, repeats no more.In like manner, automatic rollback when the local node to be upgraded of controlling in node and/or described old plane of agency in described new plane breaks down in escalation process, normally carries out business.。
Certainly, this escalation process of system has well solved the smooth upgrade of system; Does is present problem how to realize the function that the node of system locks, reshuffles, starts? only the semanteme for these functions of node is physically unclear, therefore, need to understand that the logic function of node could really realize these functions.This needs the logical model of system.The logical model of general Telecommunication Network Element equipment is as Fig. 4:
Intercom system is relatively independent in logic functional module, complete the communication task between other logic modules, scheme requires intercom system effective in whole escalation process, otherwise cannot carry out intercommunication, therefore the upgrading of intercom system is subject to certain constraint, keeps the compatibility of communication protocol between 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 the smallest object of Operation and Maintenance as fault detect, software download etc. by controlling software encapsulation.
Physical resource is the basic configuration unit of composition system physics realization, and if Node Board, stube cable etc. is all physical resource, in this programme, node is physical resource, is also the operand of escalation process.
Logical device is abstract to physical equipment by controlling that software encapsulation realizes, be the least unit of control system inside to physical equipment allocation manager, operate in the encoding and decoding speech logical device that the upper encoding and decoding process software of certain DSP may provide Liao100 road 64K as one.
The basic object that the Telecommunication Network Element device interior business realizing of logical resource need to be managed, is realized by the logical device of a plurality of difference in functionalitys conventionally, and the establishment of logical resource is by configuring completing of suitable logical device.As speech business carrying need to be passed through interface E1 equipment, inner exchanging equipment and encoding and decoding speech equipment etc.
Business Processing realizes by state machine, by the processing of the Signalling exchange finishing service with terminal or other network elements, and the normally control to local resource of result that signaling is processed.
In system upgrade process, node completes that it locks, reshuffles, the logic function module of its deployment is depended in the details behavior of start-up performance completely (being Business Processing, logical resource management, logical device management), and these functions need to be distributed to these logic function modules and realize.Following form has shown the distribution condition of these functional requirements:
For different module physics, dispose top case difference to some extent in internal control details, following example is described according to these different situations respectively.
The embodiment of the present invention three provides a kind of method for upgrading system, embodiment mono-is applied in concrete system architecture scene, system is used half to concentrate half decentralized control (master control node with from controlling node when physically separated) or centralized control when controlling node and physically unifying (master control node with from) completely, there is a master control node and from controlling the redundancy of node, under normal circumstances, master control node can be realized with active/standby mode, from controlling node, can work with N+1 backup mode, under 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 before upgrading, this agent node is redundancy master control node, and in system upgrade process, as acting on behalf of master control node, follow-up Fig. 6 to Fig. 8 is also same processing, repeats no more.
In the present embodiment, logical resource management is realized as global logic resource management and local logical resource is controlled, and Business Processing is realized as traffic assignments and business is carried out.Global logic resource management and traffic assignments are deployed in master control node, and local logical resource is controlled and business execution is deployed in from controlling node.
Escalation process is described:
The upgrading of Maintenance Point is independently carried out, and traffic affecting does not carry out, and before and after upgrading, between necessary maintenance and master control node, maintenance interface is compatible.
The upgrading of resource node has influence on corresponding logical resource control module, by contacting of lock event, registration process deletion or foundation and logical resource control module.
From controlling the upgrading of node, have influence on corresponding global logic resource and service distribution module, by contacting 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 being updated redaction from controlling the interface of node no matter, because master control node is center, plural master control node cannot independently be worked, therefore, in the process of upgrading, adopt agency mechanism: the service distribution module in two planes is processed by the signaling of Maintenance Point and two plane compatibles, mutually the distribution of forwarding service; The master control node of redaction plane is transmitted to early version master control node processing the association requests of resource management, and starts isochronous resources configuration data.When other the node except legacy version master control node has all been upgraded and joined after new plane, in legacy version plane, only had master control node, and now this master control node is in fact only that redaction master control node is served (before this, this master control node both with the mutual forwarding service of master control node of redaction plane, manage again the subordinate's of legacy version plane node to be upgraded), now can lock the master control node of legacy version, legacy version is controlled node notice redaction master control node and is switched to normal operating conditions, redaction master control synchronisation of nodes completes the data that need, redaction master control node stop Agent Status, and start autonomous processing traffic assignments and global resource management work.
Upgrading order principle is followed: master control node (agency)+from controlling 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 working cell number.
The embodiment of the present invention four provides a kind of method for upgrading system, in like manner, embodiment bis-is applied in concrete system architecture scene, system is used full control mode of disperseing, can be understood as and there is no master control node, also can be understood as by a plurality of this locality control nodes that physically disperse and form master control node.At least there is a redundant node in the local node (being original master and slave control node) of controlling, each local resource node of controlling node and control thereof forms a working cell.As shown in Figure 7:
In the present embodiment, logical resource management is realized as global logic resource management and local logical resource is controlled, wherein global logic resource management is comprised of the resource interactive module of a lot of this locality again, Business Processing is realized as traffic assignments and business is carried out, 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 dispersed and are deployed in the local node of controlling, and local logical resource is controlled and business execution is deployed in local control on node equally.
Escalation process is described:
The upgrading of Maintenance Point is independently carried out, and traffic affecting does not carry out, and before and after upgrading, between necessary maintenance and master control node, maintenance interface is compatible.
The upgrading of resource node has influence on corresponding logical resource control module, by contacting of lock event, registration process deletion or foundation and logical resource control module.
If local, controlling node needs upgrading, is progressively upgrade-system of unit so according to working cell, and escalation process needs special processing, uses a kind of mechanism that is called compatible locum, and principle as shown in Figure 8.
When a working cell of upgrading, this locality control node of a redundancy has been upgraded and has started successfully, becomes a local node of controlling of agency.In redaction plane, this standbyly local controlled service interworking module on node and can control with this locality of the legacy version of this working cell the distribution (according to certain algorithm) of the mutual forwarding service of node; This locality of redaction plane is controlled node the association requests of resource management is transmitted to the local node processing of controlling of early version, and starts isochronous resources data.The resource node of other in working cell except local control node has all been upgraded and has joined after new plane, in legacy version plane, only had local control node, and now this node is only the service of the local control of redaction node, node is controlled in this locality that now can lock the legacy version of this working cell, the local local node of controlling of Node Events notice redaction of controlling of legacy version switches, redaction master control node is suspended operation and is upgraded all synchrodatas, data stop Agent Status after synchronously completing, and start autonomous processing traffic assignments and global resource interworking.
Upgrading order principle is followed: local node (the agency)+working cell 1[of control controls node in resource node+this locality]+... node is controlled in+working cell n[resource node+this locality]+Maintenance Point, n is working cell number.
The embodiment of the present 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 controlling the new plane of node 200 establishments and the old plane at node to be upgraded place, to be upgraded from controlling node 400, resource node 500 to be upgraded); Wherein,
