Description
(1) technical field
The present invention relates to telecommunication network management (Telecommunication Management) method in a kind of telecommunication system, relate to the method for middle succedaneum (Agent) of a kind of telecommunication management network (TMN:Telecommunication Management Network) and manager (Manager) sharing information model (Information Model) in particular.
(2) background technology
TMN, it is telecommunication management network, being standardization department of international telecommunication union telecommunication (International TelecommunicationUnion-Telecommunication Standardization) is the needs of the telecommunication service of the develop rapidly that adapts to the modern telecom network technology and a multitude of names, and the network of a kind of novel managing telecommunications net that proposes.Telecommunication management network and telecommunications network are logically separate, finish the unified operation of numerous telecommunication apparatus, communication network and telecommunication service (Operation), management (Administration) and the function of safeguarding (Maintenance).Since 1985, ITU-T has formulated the international standard of a cover TMN, and (seeing also M.3000:Overview ofTMN Recommendations of ITU-T standard document ITU-T Recommendation) carried out stipulating in the aspects such as definition, architecture, administrative model and function of TMN.
TMN adopts manager and succedaneum's mode to finish management activity based on the system management model of Open System Interconnection (OSI:Open System Interconnection).Manager and succedaneum are a pair of system management entity (Entity) that (ManagementAssociation) got in touch in management of having set up, the manager sends operational order to the succedaneum, (NetworkResources) controls and manages to Internet resources, the succedaneum replys the operational order that the manager sends, the managed network resource is operated, and send circular (Notification) to the manager.A manager can set up management with a plurality of succedaneums and get in touch, and a succedaneum also can set up management with a plurality of managers and get in touch.Manager and succedaneum's role is not what fix, but determines in the management contact of each foundation.In the management of foundation contact, a system management entity or take on administrator role, the person role that perhaps do not act as agent, the then corresponding person of the acting as agent role of another system management entity with its equity (Peer) perhaps takes on administrator role.
In the system management model of OSI, the modeling technique of object-oriented (Object Oriented) in the computer science (Computer Science) has been adopted in the description of Internet resources, and the notion that has proposed managed object (Managed Objects) describes the managed network resource.Managed object is the abstractdesription to the managed network resource: the managed network resource is conceptualized as information source, information source after abstract and then encapsulate (Encapsulation) by managed object, the bulk properties of encapsulation back managed object are not extraneous finding, but provide a management interface (Managed Object Boundary) to external world by managed object, by this management interface managed object is operated, or the inner event of managed object is outwards sent (seeing also iso standard document ISO/IEC 10040:Information Technology-Open Systems Interconnection-Systems Management Overview) with the form of circular.
Might not be corresponding one by one between managed object and the managed network resource, a managed object can only be represented a kind of managed network resource, also can represent the combination of multiple managed network resource.Managed object not only can be represented the physical resource of network, can also represent the logical resource of network.By the set of all managed objects, and the correlation between the managed object, an abstract view that is constituted is called Management Information Model (Management Information Model), or abbreviates information model (Information Model) as.
In order to define the managed network resource effectively, TMN has used the managed object notion in the OSI system management model equally, with the managed network resource abstract be one by one managed object, corresponding, the management of Internet resources also is conceptualized as various operations to managed object.Only after abstract, represent, can operate the managed network resource, thereby can in TMN, adopt abstract, standardized means that communication network is managed by the management interface of managed object with managed object in the managed network resource.
In the international standard of described TMN, defined one group of managed object, constituted a general information model thus, and in all TMN, be suitable for.But, because the diversity of communication network except above-mentioned Common Information Model, also needs the managed network resource at concrete communication network, make up corresponding managed object, above-mentioned Common Information Model is expanded.For described information model after expanding, between a pair of manager and succedaneum who sets up the management contact in TMN, can finish control and management by the management interface of managed object to described Internet resources in order to make described manager; Make described succedaneum correctly reply the operational order that described manager sends, finish the operation to the managed network resource, the succedaneum also must share described managed object and information model with the manager of its opposite end.In described information model shared procedure, the manager of described succedaneum and its opposite end answers the mutual understanding following message:
A. managed object set;
B. the management interface of each managed object;
C. the correlation between the managed object.
According to aforesaid shared information, the abstract view of a managed object set of each self-generating of described succedaneum and manager, promptly described information model.Because the correlation between the described managed object is a kind of inclusion relation (HierarchicalContainment) of hierarchy, and the managed object of each subordinate is merely able to be comprised by unique higher level's managed object, therefore described information model is rendered as a kind of tree-like structure, thereby holds the information model abstract view of the generation management information tree (MIT:Management Information Tree) that is otherwise known as described succedaneum's end and manager.
By described information model shared procedure, the management information tree of described succedaneum and each self-generating of manager should be consistent, and then guarantees that the management activity between described succedaneum and the manager normally carries out.If not, the inconsistent of described management information tree may cause unpredictable mistake in the management activity, makes described manager lose control to described succedaneum, when serious even cause the paralysis of whole TMN.
Therefore, described succedaneum and manager should guarantee that as much as possible the management information tree of its each self-generating is consistent by the shared procedure of information model, and in time find and correct the inconsistency that exists in the described management information tree.But, whether exist in the inconsistent method at the described management information tree of detection at present, normally operational order and the described succedaneum that described manager is sent carries out syntax check to replying of described operational order, for example: check whether the managed object of pointing in the operational order that described manager sends exists in described succedaneum's management information tree; Check whether described succedaneum correctly replys the operational order that described manager sends, by such syntax check, that can find to exist in the described management information tree is obviously inconsistent, but for more hidden inconsistency, be that this class inconsistency only can cause the mistake in the management activity under particular condition, described syntax check method will be difficult to be suitable for.
(3) summary of the invention
The objective of the invention is to propose the method for succedaneum and manager sharing information model among a kind of TMN, can simplify the shared procedure of described information model, reduce that inconsistent possibility appears in management information tree described in the described information model shared procedure, and in time find and correct the inconsistency that exists in the described management information tree.
Above-mentioned goal of the invention is to realize by following method: the method for succedaneum and manager sharing information model in the telecommunication management network is characterized in that the reference format that described succedaneum and described manager use both sides to arrange carries out sharing of information model; The label that comprises described sharing information model in the described reference format; Described succedaneum and described manager compare the information in the described information model label in carrying out the shared process of information model; When comparative result shows information inconsistency in the described information model label, described succedaneum or described manager will describe with the reference format of the synchronous described sharing information model of the opposing party of its opposite end.Described reference format is set up in the initial handshake process that management gets in touch succedaneum and manager and is consulted to determine, perhaps be the reference format that succedaneum and manager both sides give tacit consent to.Comprise the start context information of information model, the rise time information and the cyclic check position information of information model in the label of described information model.Described reference format adopts the form of form or uses the mode of extend markup language or ASN 1 to be described, described succedaneum and described manager and then can describe according to described criteria table or XML, utilize the described management information tree of each self-generating of computer program, comprise described succedaneum and manager institute Sharing Information model version mark in the described management information tree.Described succedaneum and described manager compare the information in the described information model label in the initial handshake process that the foundation management is got in touch.When comparative result shows information inconsistency in the described information model label, described succedaneum or described manager are when describing with the reference format of the synchronous described sharing information model of the opposing party of its opposite end, described succedaneum or described manager all can be used as a main synchronous side, the then corresponding conduct of the opposing party of its opposite end is by a synchronous side, under default situations, described manager is a main synchronous side, and described succedaneum is by a synchronous side.A main synchronous direction is described by the reference format that a synchronous side transmits described sharing information model, or by being described from the reference format that a main synchronous side downloads described sharing information model by a synchronous side.The synchronous root of described quilt regenerates its management information tree according to the reference format description of its described information model that obtains from a main synchronous side.
The reference format of the synchronous described sharing information model of the opposing party of described succedaneum or described manager and its opposite end describe finish after, described succedaneum and described manager compare the information in the described information model label once more.
In the method for succedaneum and manager sharing information model, described telecommunication management network is the supervising the network of 3G (Third Generation) Moblie Radio Access Network in described telecommunication management network.Described 3G (Third Generation) Moblie Radio Access Network is a time-division-synchronous CDMA access system.

Below with reference to accompanying drawing, method of the present invention is further described by specific embodiment.
The communication network that TMN can manage comprises Public Switched Telephony Network (PSTN), public land mobile communications network (PLMN), private voice network, Integrated Service Digital Network, Intelligent Network and TMN self etc.
The third generation (3G) mobile communications network is intended to provide big capacity, two-forty, support multiple business, public land mobile communications network of new generation with whole world unified standard, accordingly, the supervising the network of 3G mobile communications network also is devoted to change in the supervising the network of the second generation (2G) mobile communications network, between different suppliers' supervising the network because of incompatible problem that can not interoperability, realization is to the network equipment of numerous suppliers in the 3G mobile communications network, the communication network of numerous operators and numerous service providers' communication service, the target of using unified standardized method to manage and safeguard, simplify the design of the supervising the network of 3G third generation mobile communication network, reduce the cost of the supervising the network of 3G mobile communications network.
The standardization effort of the supervising the network of 3G mobile communications network adopts the notion of TMN, and same use and management person finishes management activity with succedaneum's mode, uses managed object and information model to describe the managed network resource.And, the standardization effort of the supervising the network of 3G mobile communications network also is devoted to propose common information model, it is independent of each supplier's concrete managed network resources such as the network equipment, has unified standard management interface, realizes general management to various heterogeneous networks equipment with this.
Though the standardization effort of the supervising the network of 3G mobile communications network has adopted the TMN notion, and proposed to make up the target of described common information model, but how to realize interoperability between supervising the network and the supervising the network for how to construct, TMN also furthers investigate.And in the 3G mobile communications network, include numerous network equipments from variant supplier, need to support diversified communication service, the realization of each communication service all will relate to networks of different type equipment usually, therefore in the present standardization effort stage, except the common information model that is proposed, still need at concrete managed network resource, make up corresponding managed object and information model, (see also 3G mobile communications network standard document 3GPP TS 32.101:Telecommunication management in order to contain whole 3G mobile communications network and supervising the network thereof; Principlesand high level requirements).
For example, Time Division-Synchronous Code Division Multiple Access inserts (TD-SCDMA:Time Division-Synchronous Code DivisionMultiple Access) system, it is as a kind of wireless access network in the 3G mobile communications network (Radio Access Network), comprise a plurality of Node B (Node B) and network controller (RNC), as shown in Figure 1.Link by the Iur interface between the heterogeneous networks controller, link by Iub interface between network controller and its Node B of controlling.Time-division-synchronous CDMA access system is that end user device (User Equipment) provides the wireless access service by the Uu interface, and links by Iu interface and core net (CoreNetwork).
The supervising the network of time-division-synchronous CDMA access system is as shown in Figure 2: wherein, operation and maintenance center (OMC:Operation and Maintenance Center) is in the management of setting up respectively with Node B and network controller is got in touch, take on administrator role, the remote centralized management to Node B and network controller is provided; Node B LMT Local Maintenance Terminal (LMT-b:LocalMaintenance Terminal-Node B) is taken on administrator role in getting in touch with the management of Node B foundation, the local management function to Node B is provided; Network controller LMT Local Maintenance Terminal (LMT-r:Local Maintenance Terminal-RNC) is taken on administrator role in getting in touch with the management of network controller foundation, the local management function to network controller is provided; Node B and network controller are in getting in touch with the above-mentioned management of operation and maintenance center and LMT Local Maintenance Terminal foundation, and the person role that all do not act as agent carries out the operational order that above-mentioned manager sends.
In the management operation instruction that Node B is carried out, part instruction relates to the control of network controller to the Node B logical resource, for example network controller is to the channel resource of Node B, the control of local resource, this part instruction is irrelevant with the specific implementation of node b apparatus, is called logical operation and safeguards (Logical O﹠amp; M:Logical Operation and Maintenance).Logical operation and maintenance function belong to network controller to be owned, the category that does not belong to the supervising the network of time-division-synchronous CDMA access system defines (seeing also 3G mobile communications network standard document 3GPP TS 25.433:UTRAN Iub interface NBAP Signaling) by node B application part (the NBAP:Node B Application Part) standard of Iub interface.
In the management operation instruction that Node B is carried out, another part instruction relates to safety management (Security management), configuration management (Configuration Management), performance management (Performance management) and fault management bookkeepings such as (Faultmanagement), is the supervising the network functional category of time-division-synchronous CDMA access system.This part management operation instruction is relevant with the specific implementation of node b apparatus, is called to realize relevant operation and maintenance (Implementation SpecificO﹠amp; Or be called private operations and safeguard (Proprietary O﹠amp M); M).
In time-division-synchronous CDMA access system, described a plurality of Node B and network controller can be provided by the consolidated network equipment supplier, also may come from different network equipment suppliers.In order to finish the Network Management Function of time-division-synchronous CDMA access system, as mentioned above, except described common information model, also need Node B and network controller at the heterogeneous networks equipment supplier, make up corresponding managed object and information model; Accordingly, the succedaneum, as come from heterogeneous networks equipment supplier's Node B and network controller, the manager of palpus and its opposite end, as operation and maintenance center or LMT Local Maintenance Terminal, share described information model, thereby make the manager finish long-range or or local management function by the management interface of managed object.
The method according to this invention, Node B or network controller are as the succedaneum, with share as gerentocratic operation and maintenance center or LMT Local Maintenance Terminal in the process of described information model, the reference format of both sides' agreement will be adopted, managed object is gathered, the management interface of each managed object, and the correlation between the managed object is described.The reference format of described both sides agreement can be set up succedaneum and manager and consult definitely in the initial handshake process (Handshaking) that management gets in touch, and also can be the reference format of giving tacit consent to.Comprise a top object (Top Level ManagedObject), a plurality of device-dependent object (Equipment Related Managed Objects) and a plurality of object relevant (Function Related Managed Objects) in the set of described managed object with function; The management interface of described managed object is made of attribute (Attribute), operation (Operation), behavior (Behavior) and circular (Notification), as shown in Figure 3: the wherein characteristic of the described managed object of attribute representation or feature; The operation that operation expression can be carried out described managed object; The response of described managed object to described operation represented in behavior; The behavior that the described managed object of circular expression is outwards sent its internal event; The inclusion relation of hierarchy is described by parent object (Parent Object) and subobject (Son Object) between the described managed object, as shown in Figure 4; The method according to this invention also further comprises in the described reference format label of described information model comprising following information in the described label:
A. the start context of information model
B. rise time of information model
C. cyclic check position (CRC:Cyclic Redundancy Check)
In order to described succedaneum and manager institute Sharing Information model version are carried out mark.In addition, can also comprise some other optional information as required in the described label.
The reference format of described succedaneum and manager's agreement can use the form of form, also can use extend markup language (XML:Extensible Markup Language) or ASN 1 modes such as (ASN.1:Abstract Syntax Notationone) to be described.Described succedaneum and manager and then can describe according to described criteria table or XML, utilize computer program to generate described management information tree automatically, also will comprise described succedaneum and manager institute Sharing Information model version mark in the described management information tree accordingly.
Because in the process of described succedaneum and manager sharing information model, used the method for the both sides' arranged standard form among the present invention, thereby can reduce the error rate in the described information model shared procedure, reduce described management information tree and inconsistent possibility occurs; Again because described reference format can use form or computer identifiable language to be described, can also simplify the shared procedure of described information model simultaneously.
Utilize the described information model version flag in described succedaneum and the described manager both sides' management information tree,, can in time find the inconsistency that exists in the described management information tree by the described information model version flag of both sides is compared.For example, can set up in the initial handshake process that management gets in touch described succedaneum and manager, by following handshake steps, wherein the handshake information of issuing described succedaneum by described manager comprises following parameter:
A) described manager's sign
B) described gerentocratic password
C) described manager holds the information model version flag in the management information tree
Described succedaneum comprises following parameter to the response of described manager's handshake information:
A. described succedaneum's sign
B. described succedaneum holds the information model version flag in the management information tree
Described succedaneum and described manager institute Sharing Information model version are compared, when both sides' information model version flag is consistent, illustrate that promptly the management information tree of described succedaneum and manager end is consistent; Otherwise, found in time that promptly there is inconsistency in the management information tree of described succedaneum and manager end.
Further, the method according to this invention, when through above-mentioned comparison procedure, when finding that the information model version of described succedaneum and described manager end is inconsistent, described succedaneum or described manager will with the reference format description of the synchronous described sharing information model of the opposing party of its opposite end.Described succedaneum or described manager are when describing with the reference format of the synchronous described sharing information model of the opposing party of its opposite end, and described succedaneum or described manager all can be used as a main synchronous side, and the then corresponding conduct of the opposing party of its opposite end is by a synchronous side; Under default situations, described manager will be a main synchronous side, and described succedaneum then is by a synchronous side; A main synchronous side will describe to the reference format that is transmitted described sharing information model by a synchronous side, perhaps by being described from the reference format that a main synchronous side downloads described sharing information model by a synchronous side; After the reference format that has successfully obtained described sharing information model from a main synchronous side is described, regenerated its management information tree by a synchronous side, and send response message to a main synchronous side; For example, when described manager is a main synchronous side, and a main synchronous side will be when the reference format that is transmitted described sharing information model by a synchronous side be described, and concrete steps are: described manager comprises the message of following parameter to described succedaneum's transmission:
A) described manager's sign
B) described gerentocratic password
C) described manager holds the information model version flag in the management information tree
D) reference format of described manager's client information model is described
After described succedaneum successfully receives above-mentioned message, reference format according to information model described in the above-mentioned message is described, described succedaneum will regenerate its management information tree, and send the response message that comprises following parameter to described manager, and expression is finished synchronously:
A) described succedaneum's sign
B) the information model version flag after described succedaneum holds synchronously
The reference format of the synchronous described sharing information model of the opposing party of described succedaneum or described manager and its opposite end describe finish after, whether described succedaneum and described manager also can compare the information in the described information model label once more, correct synchronously in order to verify.Find out thus, inconsistent for what exist in described succedaneum and the described administrator administers inforamtion tree in the shared procedure of described information model, by the above-mentioned steps among the present invention, also can further in time correct it.
