Description

The method of calibration of the network resource uniformity of webmaster and network element and system thereof

Technical field

The present invention relates to the communications field, particularly network management technology.

Background technology

Nearly 2 years, communication network was accepted and practical application by vast user gradually owing to maturation, the downward modulation of price, the reasons such as enhancing of security performance gradually of technology.

But on the other hand, how further to reduce the influence of various factors, remain the present field that needs to make great efforts research telecommunication network service quality.

For instance, because in the wireless network mainly is to carry out data information transmission by microwave signal in air, therefore natural weather situation, building obstacle, and can cause interruption, the decay of wireless network signal, thereby reduce the application enthusiasm of user to radio network technique with the reasons such as mutual interference mutually of other microwave signals.

This shows that more and more emphasizing to be applied as under the leading development trend, for Network Management, especially the management to wireless network has become a great problem of pendulum in face of manufacturer, user.

The purpose of network management is, increase the up duration of network to greatest extent, improve utilance, network performance, service quality, fail safe and the economic benefit of network element, simplify management and Control Network operating cost under multi-modulation scheme, the multi-vendor hybrid network environment, the foundation of the network planning is provided.It comprises functions such as operation, management, maintenance, also comprises the various key technologies and the software and hardware instrument of the normal operation of maintaining network simultaneously.

Comprise network element (Network Element is called for short " NE ") and NE management (Element Management is called for short " EM ") in the telecommunication management network.Wherein, the network resources model of each NE portion good at managing oneself, the network resources model of EM all NE good at managing.

The network resources model of NE and EM is distributed in different places, because a variety of causes, the network resources model of NE and EM may exist inconsistent, and this will cause EM that deviation is appearred in the management of NE.Therefore should be able to check out where both network resources models exist fast inconsistent for EM, so that take measures to eliminate this inconsistent rapidly, guarantees that EM manages normally to NE.

Generally speaking, the consistency alternative of the network resources model of EM and NE is, NE exports to extensible markup language (EXtensible Markup Language to network resources model, be called for short " XML ") file or binary file, NE uploads to EM to the file of deriving, and EM obtains out the network resources model of NE then from file, compare with the self networks resource model, thereby whether consistent, and which object exists inconsistent if drawing network resources model.

But there is following shortcoming in this scheme:

1. efficient is low: EM need read out the attribute one by one of the object one by one of the network resources model of NE, compares with the self networks resource model then, and efficient is low;

2.EM amount of calculation is big: if NE has 500,000 objects, 20 attributes of each object, then EM need carry out 1,000 ten thousand times comparison.EM need carry out verification to all NE of its management, and the verification amount of calculation is very big, can impact other business of EM.

3. the information interaction amount is big: NE exports to XML file or binary file to network resources model, and with 10 bytes of each Property Name of previous example, 4 bytes of each property value are calculated, and it is up to a hundred million that the XML file of derivation has, and NE and EM information interaction amount are very big;

4. promptness is poor: because amount of calculation and the information interaction amount of EM are big, EM can not often carry out network resources model consistency check, so the promptness of consistency check is poor.

The another kind of method of calibration of the network resources model of EM and NE is, NE in a certain order, the property value of all-network resource model is arranged out, with cyclic redundancy check (CRC) (Cyclic RedundancyCheck, be called for short " CRC ") the algorithm computation sequence of attributes, then the CRC check value is issued EM, EM calculates a CRC check value with same method, relatively whether both are consistent, thus the network resources model of EM and NE consistency whether relatively.

But still there is following shortcoming in this scheme:

1. reliability is low: if the network resources model of NE and EM differs bigger, the CRC check value that probably calculates is still the same, thereby draws the illusion of network resources model unanimity;

2. amount of calculation is big: NE and EM need the network resources model serializing separately, and the result to serializing calculates the CRC check value then, so amount of calculation is bigger;

3. can not navigate to which object exists inconsistent: inconsistent if EM compares, and it is inconsistent not know which object exists, and also needs other method to obtain inconsistent object again.

Summary of the invention

In view of this, main purpose of the present invention is to provide the method for calibration and the system thereof of the network resource uniformity of a kind of webmaster and network element, makes that the consistency desired result of network resources model can carry out fast and reliably between webmaster and network element.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

Core of the present invention is, is respectively each resource object by webmaster and network element and generates verification attribute, and increase or upgrade corresponding verification attribute during change at the configuration attribute of resource object.Network element is uploaded to webmaster with each resource object and verification attribute thereof, by the webmaster verification attribute of each respective resources object of this webmaster and this network element relatively one by one, carries out the consistency desired result of Internet resources.

More than core of the present invention has been done simple declaration, be described in detail according to the method for calibration of this principle below the network resource uniformity of first execution mode webmaster of the present invention and network element.

As shown in Figure 1, in step 110, webmaster and network element are respectively each resource object and generate the verification attribute.Specifically, the network resources model of network element generally presents in the mode of management information tree, and as shown in Figure 2, this management information tree is one and contains tree, a node in the corresponding management information tree of each resource object of network element.And the network resources model of webmaster has comprised the network resources model of all network elements, so network element is a subtree of the management information tree of webmaster.If the network element shown in Fig. 2 is radio network controller (Radio Network Controller is called for short " RNC "), then the network resources model of webmaster has comprised the management information tree of network element as shown in Figure 3.This shows, the network resource uniformity verification of webmaster and network element, just whether each is consistent with corresponding resource object in the network resources model of webmaster as the resource object of node in the management information tree of verification network element.

Therefore, in this step, for each resource object, webmaster and network element generate verification attributes according to all configuration attributes of this resource object respectively, and this verification property value is exactly the check value that all configuration attributes of this resource object are calculated with checking algorithm after the serializing in order.Wherein, checking algorithm can be CRC check, parity check or Hamming check.In these checking algorithms, the parity check sum Hamming check generally is used for the fewer situation of byte, and Hamming check has error correction, amount of calculation is bigger, and CRC check is a most widely used verification mode in the network communication, and its amount of calculation is little, and it is simple and reliable, therefore, comparatively speaking, CRC check more is applicable to and generates the verification attribute.If the verification attribute of each resource object all obtains with the CRC algorithm after the serializing in order according to the configuration attribute of this resource object, can realize the reliability of this verification attribute quickly and easily.Certainly, when the configuration attribute of resource object increases or during change, need be according to increasing or after changing configuration attribute upgrades the verification attribute of this resource object, to guarantee the reliability of this verification attribute.Can there be multiple mode to realize serializing in order, for example, can be to configuration attributes all in the resource object by ID generic sequenceization from small to large, also can be by generic sequenceization of configuration attribute names letters or the like.

Then, enter step 120, network element uploads to webmaster with the sign and the verification attribute thereof of each resource object.Specifically, each resource object as node all has object type ID (object type identification number) and object instance ID (object instance identification number) in management information tree, object type ID and object instance ID combination unique identification a resource object.For the consistency desired result of the network resources model that makes webmaster and network element not only can compare inconsistent resource object, can also be after comparing inconsistent resource object, compare the position of inconsistent resource object in tree apace, network element also needs the structural information (comprising that each resource object is with respect to the level in the management information tree) of management information tree and the sign and the verification attribute thereof of this resource object are together uploaded to webmaster.Such as, network element is according to the algorithm traversal management information tree of first root traversal, resource object for same level travels through in proper order according to object type ID, object instance ID, obtain resource object, and the sign and the verification attribute thereof of each resource object uploaded to webmaster according to this order through ordering.Be appreciated that the structural information that has just comprised management information tree among the result to the management information tree traversal.Network element can upload to webmaster with the sign of each resource object and the verification attribute of this resource object by file, such as, network element is saved in the sign of corresponding resource object and the verification attribute of this resource object in the file successively according to the order that the traversal management information tree obtains, and again this document is uploaded to webmaster.If the resource object number in the management information tree of network element is less, also can directly the sign of each resource object and the verification attribute of this resource object be uploaded to webmaster, organize sequence consensus in this message in the tissue of information order and the file mode by message.

Then, enter step 130, webmaster is the verification attribute of more corresponding resource object one by one.Specifically, webmaster obtains resource object through ordering in identical traversal mode, and the relatively sign and the verification attribute thereof of this webmaster and each respective resources object of this network element are successively finished the consistency desired result of Internet resources.At above-mentioned case, webmaster travels through the management information tree of this network element that is comprised in the network resources model of this webmaster equally according to the algorithm of first root traversal, for the resource object of same level according to object type ID, object instance ID travels through in proper order, obtain resource object through ordering, and the sign and the verification attribute thereof of each resource object are preserved into file according to this order, when the file received from the sign of preserving each resource object of this network element and verification attribute thereof, compare this webmaster and the sign of the resource object of this network element and the verification attribute of this resource object successively one by one, finish the consistency desired result of Internet resources.Because the attribute of each resource object is limited, therefore, can guarantee the accuracy of assay by comparing the verification attribute of resource object.And, since in the file relatively except the verification attribute of the sign that comprises each resource object and this resource object, also comprised the structural information of management information tree.Therefore, not only can check out webmaster whether consistent, can also after comparing inconsistent resource object, compare the position of inconsistent resource object in tree apace with the network resources model of network element.

In addition, what deserves to be mentioned is, in the present embodiment, whole checking procedure network element and webmaster are less alternately, and network element only need generate the resource object message file, and webmaster is except that spanned file, also only need carry out file relatively, therefore algorithm is simpler, and inspection process is controlled easily, thus guarantee webmaster can be in time, rapidly, check out whether this webmaster consistent with the network resources model of this network element accurately.

The check system of the network resource uniformity of second execution mode webmaster of the present invention and network element comprises a network element and a webmaster as shown in Figure 4.

In network element, comprise be used to each resource object according to its all configuration attributes generate the verification attributes verification attribute generation module, be used for that configuration attribute at resource object increases or upgrade during change corresponding verification attribute update module, be used to travel through management information tree and obtain through the sign of the resource object of ordering and the spider module of verification attribute, with last transmission module, be used for the sign and the verification attribute of the resource object through sorting of spider module generation in this network element are uploaded to webmaster.

In webmaster, comprise be used to each resource object according to its all configuration attributes generate the verification attributes verification attribute generation module, be used for that configuration attribute at resource object increases or upgrade during change corresponding verification attribute update module, be used for traveling through the management information tree of this network element that network resources model was comprised of this webmaster in the traversal mode identical with network element, obtain through the spider module of the sign of resource object of ordering and verification attribute and be used for successively the relatively comparison module of the verification attribute of each respective resources object of this webmaster and this network element.Because the attribute of each resource object is limited, therefore, can guarantee the accuracy of assay by comparing the verification attribute of resource object.The verification property value is exactly the check value that all configuration attributes of this resource object are calculated with checking algorithm after the serializing in order.Wherein, checking algorithm can be CRC check, parity check or Hamming check.If the verification attribute of each resource object all obtains with the CRC algorithm after the serializing in order according to the configuration attribute of this resource object, can realize the reliability of this verification attribute quickly and easily.

In addition, by the comparison module relatively sign of the resource object of this webmaster and this network element and the verification attribute of this resource object successively, not only can check out webmaster whether consistent with the network resources model of network element, can also after comparing inconsistent resource object, compare the position of inconsistent resource object in tree apace.

Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
