The present invention is characterized in that the method comprises the following steps that in the process of an administrator part, a request for communal management information service CMIS is sent to a proxy; in the process of a proxy part, management information bases MIB for network elements are built; when a system is started, proxies at each level load corresponding management information bases MIB for network elements; each proxy information in the system forms a globally uniform management information tree MIT according to the cascade connection relation; the request for communal management information service is analyzed, and a CMIS primitive is carried out on the management information tree. Compared with the prior art, the present invention controls the network element management range of an administrator through the cascade connection relation of the proxies and realizes the transparent operation in the whole system; the present invention reduces the system cost, enhances the work efficiency and the accuracy and saves the expenditure of communication maintenance to a very large extent.
Description
Technical field
The present invention relates to the mobile network management field, especially relate to a kind of implementation method of agency (Agent) colony dynamic cascading in the cdma mobile communication network management system.
Background technology
In the prior art, telecommunications network comprises core net and managerial grid.Wherein, Telecommunication Management Network N (TelecommManagement Net) logically can be divided into five layers, and bottom two-layer is respectively NE management layer and Network Element Layer.Network Element Layer mainly is meant the CDMA network element in the packet-based core networks, as HLR/AUR, MSC/VLR, BTS, BSC etc.In the operation of reality, operator wishes and can realize multiple management to a network element inside the province at NE management layer, for example: can be divided into provincial management, city-level management (or local maintenance center), local (office) management etc., every grade of network element number of being managed and scope are all inequality: provincial, be in charge of the network element of whole province; At the local maintenance center, be in charge of all network elements in this area under one's jurisdiction; In this locality, be responsible for a NE management to this locality.
In the telecommunication management network, message structure adopts " manager/agency " pattern, and " manager " is responsible for the management logic of treatment system; " agency " is responsible for directly and network element is mutual and carry out public administration information service CMIS (the Common Management Information Service) request that the manager sends.Therefore, if " manager " needs certain regional network element of management, just must send request to its " agency " directly or indirectly.
At first, in the prior art, mainly be to adopt the respectively mode of " manager " own cascade of mode that " manager " and the agency of all network elements of this area directly link to each other or employing, satisfy the demand of NE management layer multiple management.But these two kinds of ways all exist following shortcoming:
1. " manager " is difficult to unified: because " manager " is different in the requirement of different levels management, if the network element of " manager " cascade or direct and bottom is mutual, then in maintenance centre at different levels, need carry out certain extraction to information, be difficult to accomplish that identical " manager " can carry out unified management to network element in different levels;
2. networking is single, and structure is dumb, is difficult to realize distributed control: when a public administration information service CMIS request related to a plurality of network element, " manager " need carry out extremely complicated affairs control; For example: provincial NE management center need link to each other with all network elements, when the network element of a province more for a long time, provincial Manager needs communication maintenance costs greatly.
Secondly, in existing standard, though also adopt Cascading Methods, it mainly is the cascade at network management center and NE management layer or higher system level, and what emphasis solved is standard and interoperability, and does not have to solve the problem at the multi-stage cascade of Network Element Layer.
Summary of the invention
Purpose of the present invention is just at the defective that exists in the above-mentioned background technology, propose a kind of telecom network management system cascade and act on behalf of implementation method, employing multi-stage cascade agency, by to the management information of network element and agency's unified Modeling, form telescopic distributed dynamic, multistage Agent structure, so that make up Element management system flexibly, easily at NE management layer.
A kind of telecom network management system cascade proposed by the invention is acted on behalf of implementation method, it is characterized in that this method may further comprise the steps:
Manager's part:
(1) sends public administration information service request CMIS to the agency;
Act on behalf of part:
(2) make up NE management information bank MIB;
(3) when system start-up, agencies at different levels load corresponding net element management information bank MIB;
(4) each proxy information in the system constitutes the unified management information tree MIT of the overall situation with cascade system;
(5) analyze described public administration information service request, management information tree is carried out CMIS primitive;
If management information, is directly carried out the CMIS operation in the corresponding levels;
If management information not in the corresponding levels, just by virtual MO, will ask directly to be forwarded to the Agent of subordinate, till the remote agent that is forwarded to direct managed network element;
(6) after remote agent is received the CMIS request of transmitting, local MO is carried out the CMIS operation, then the result is returned to higher level's agency.
Compared with prior art, the present invention is by the cascade connection of " agency ", control the NE management scope of " manager ", " manager " only needs to insert one of them " agency ", just can manage regional network element, and, can be by unified Modeling to Agent and MIT, the net element information that makes the Manager of different administrative structures can visit each area under one's jurisdiction with unified method, realized the transparent operation in the whole system, reduce system cost, improved operating efficiency and accuracy, saved the communication maintenance costs largely.
Be elaborated below in conjunction with embodiment and with reference to the technical scheme of accompanying drawing to this invention.

Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
The method of proxy cascading proposed by the invention is carried out unified modeling with the information model of network element with the agency.Wherein, the cascade between each " agency " is dynamic.Distributed control is exactly by the cooperation between " agency ", concentrates on solution between " agency ".Therefore the manager only need insert " agency " of different levels, just can manage the network element of different regions, and need not participate in too complicated affairs and other distributed controls.
As shown in Figure 1, message structure schematic diagram for TMN, telecommunication administration is the process of an information processing, X.701 system management model (the System Management Model) definition in advising according to ITU-T, each specific management is used, the effect that all has manager, succedaneum two aspects.In the Manger/Agent architecture, " manager " 101 1 sides, user's request is managed for configuration, and realizes every bookkeeping by transmission public administration information service request (CMIS); " agency " 102 1 sides, Internet resources are managed with inforamtion tree structure MIT, and according to Telecommunication Management Network (TelecommManagement Net) standard and at various NE types, generate management information bank (MIB, ManagementInformation Base), at this, " succedaneum " but resource in the direct control management information bank, promptly network element 103; And these network elements can be provided by network entity MSC/HLR, and are last, reported the operating result of the Action Events that this request starts again to " manager " by incident preceding commentaries on classics discriminator EFD (Event Forwarding Discriminator) by " agency ".
As shown in Figure 2, be the tree schematic diagram of " agency " information, wherein, Manager A 201 realizes promptly can managing regional network element to control and the manipulation of whole M IT in the system by Agent a 202; And the network element that 203 Management Agent j 204 of Manager B and the Agent of subordinate (as Agent m and Agentn) thereof link to each other; Learn that thus one " succedaneum " links to each other with a network element, by distributed cascade, configuration information is set between each " succedaneum ".If several network elements need be managed concentratedly in an area under one's jurisdiction, then all " agencies " in this same area under one's jurisdiction must link to each other with same higher level " agency ".Higher level Agent further tandem constitutes higher level tandem Agent, thereby forms the Agent tree of tree.Higher level " agency " can also can directly manage network element at the corresponding levels by coupled subordinate " agency " indirect control lower level network element.Manager only need link to each other with the top Agent in a certain area just can manage all network elements in this area, and needn't link to each other with each Agent.
Therefore, in multistage networking provided by the present invention, if " manager " when inserting " agency " of different levels, just can manage the interior network element of different regions scope.
As shown in Figure 3, be " agency " the method schematic diagram with MIT (management information tree) unified Modeling, wherein, in order to realize unified visit and the quick indexing to all network elements, the present invention invents a management object MO with " succedaneum ", is called Agent[MO].Agent[MO] according to the cascade connection of its corresponding Agent in Agent tree, generate inforamtion tree; And, use Agent[MO] and replace the root node of information model among the Agent, so, Agent tree and MIT have formed a virtual information model GMIM of global administration (global management information Mode).
Wherein, in order to reduce the coupling of two trees, and the flexibility that strengthens operation, the present invention also becomes above-mentioned modelling the structure of a secondary tree: the first order is the index tree (Agent index tree) of Agent, and the second level is MIT, Agent[MO
n] be mapped to Agent
nInformation model MIT
nOn.
As shown in Figure 4, find the incident schematic diagram with dynamic cascading new " agency " during networking of the present invention automatically, AIT is dynamic change along with the cascade structure of Agent itself, and certainly for simplicity, it also can adopt static configuration.Just as society an of colony, each Agent is safeguarding an information model to Agent tree, realizes certain management function.When increasing a network element, only need to add an Agent at the corresponding level of Agent tree, Manager just can manage this newly-increased network element then.In order to realize the dynamic change of cascade structure, the present invention adopts two kinds of methods--and find automatically and HeartBeat, form a dynamically quick reaction chain.When new Agent added Agent tree, original Agent is the initiate Agent of perception automatically, and set up certain relation with it, revised inner relevant " succedaneum " inforamtion tree simultaneously.Can set up a correct cascade connection between the Agent in order to make, be required to be initial networking strategy of Agent planning, the networking strategy here is meant the incidence relation descriptor between the Agent of the superior and the subordinate, comprise two parts information, a part is the identification number of the immediate superior Agent of Agent: Agent[ID]
f, another part is the identification number set of its direct Agent of subordinate: S{Agent[ID]
c.Above-mentioned two information all are optionally, and change along with the variation of environment at run duration.
1. find automatically: it includes two functional part: response and discovery.When new Agent added Agent tree, the step of finding was as follows automatically:
Incident 401:Discovery (active searching), that is: utilize the direct Agent of subordinate the identification number S set Agent[ID]
cSearch its corresponding Agent of subordinate automatically, and and its set up cascade connection; If this new Agent agrees as its superior agency in subordinate, just write down the id information of higher level Agent automatically, give sure response with Response; If refusal just provides negative response, the discovery incident of higher level Agent is just deleted the index of the Agent of this subordinate from AIT at this moment, and revise initial networking strategy, that is to say, the only corresponding higher level Agent of initiate Agent, but may there be the corresponding Agent of subordinate;
Incident 402:Response (reporting automatically), that is: the new identification number Agent[ID that adds the immediate superior Agent of Agent of utilization]
fInformation spinner trend higher level Agent report the message that adds Agent tree.If higher level Agent receives solicitation message, discovery just increases the index of this Agent in AIT, and revises the networking strategy; If initiate Agent need restart, then add Agent tree with the networking policy information after changing after the operation regular period.
2.HeartBeat: be meant the jumping message of making up one's mind periodically mutually between the Agent that sets up cascade connection, determine whether the other side exists.For fear of the load of too much increase communication, heartbeat message length should be short more good more, and set rational eartbeat interval.When higher level Agent finds that subordinate does not exist at certain time intervals, just revise AIT and networking strategy automatically.When the Agent of subordinate finds that higher level Agent does not exist, will control the reporting of network element data of collections such as alarm, performance.
As shown in Figure 5, be the operational flowchart by the unified visit of cascade Agent MIB provided by the invention, it comprises the two large divisions: manager's operation part and agent operation part, wherein manager's operation part comprises step 501, agent operation partly comprises step 502 to step 509, and the concrete steps of this flow process are as follows:
At first, Manager sends CMIS request, step 501; Agent retrieval agent inforamtion tree AIT, step 502, Agent judges according to the BOI and the Scope of CMIS request, the MIB to the corresponding levels operates step 503; If CMIS is not the MIB request of operating to the corresponding levels, then transmit this CMIS request, step 504 to next stage Agent; If CMIS is to MIB request of operating at the corresponding levels, then carry out the CMIS operation, step 505; After operation is finished, judge that whether Manager is in the corresponding levels, step 506; If Manager is in the corresponding levels, with regard to combined data, step 507; And direct return result, step 508; If not, just the result is returned to higher level Agent, till the Agent that the result is returned to the Manager access, step 509.
Wherein, Manager links to each other with a top Agent in its area under one's jurisdiction, when receiving the management request, according to unified method, structural belt can be distinguished the CMIS request of a DN (Distinguished Name), send the CMIS request to the Agent at the same level with it then, the CMIS primitive that is to use alternately of Manager here and Agent is realized.
In the above-mentioned primitive operation, the MO that four kinds of primitive operations are arranged may be that { MOn}, they are respectively m_get, m_set, m_invoke and m_delete to a S set.S{MOn} may be distributed among the same Agent, also may be distributed among the different Agent.
After the execution in step 503, as base object example BOI (Base Object Instance) when being not root node, then the involved MO of Scope must be in an Agent, and inserting Agent this moment only needs directly CMIS message to be transmitted to the corresponding Agent of subordinate; As BOI during at root node, and Scope relates to the operation of which floor MO under the BOI, and then the CMIS request is forwarded to the Agent of all subordinates respectively.
