Description

Carry out the method that resource discharges

Technical field

The present invention relates to the communication technology, carry out the method that resource discharges after particularly breaking down in the communication system.

Background technology

Along with development of science and technology, communication the passed by first generation and the second generation enter period of the third generation.First generation mobile communication system is the cell mobile communication systems of simulation standard, the time be this century middle nineteen seventies to the eighties mid-term; Second generation mobile communication system is a purpose with transporting speech and low-speed data service, therefore is called the narrow-band digital communication system again; Developed into the 3rd mobile communication system at present, target is wideband multimedia communication.Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division MultipleAccess is called for short " WCDMA ") is one of global at present three kinds of main 3G (Third Generation) Moblies (The ThirdGeneration is called for short " 3G ") system.As shown in Figure 1, the WCDMA system is made up of three parts, be core net (Core Net, abbreviation " CN "), universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network, be called for short " UTRAN ") and subscriber equipment (UserEquipment is called for short " U E ") composition.Wherein, the interface definition of CN and UTRAN is the Iu interface, in detail can be with reference to agreement 25.413, and the interface definition of UTRAN and UE is the Uu interface, in detail can be with reference to agreement 25.331.

The structure of UTRAN as shown in Figure 2, it comprises many RNSs (Radio Network Subsystem, be called for short " RNS ") that are connected to CN by the Iu interface.A RNS comprises a radio network controller (Radio Network Controller is called for short " RNC ") and one or more base station (Node B).As shown in Figure 2, Node B is connected on the RNC by Iub interface, can be with reference to agreement 25.433,25.423.Each Node B comprises one or more sub-districts.In UTRAN inside, the RNC among each RNS can pass through Iur interactive interfacing information, and the Iur interface can be the directly continuous of physics between the RNC or pass through suitable transmission network and realize that the regulation of relevant this interface also can be with reference to agreement 25.433,25.423.

Third generation partner program (3rd Generation Partnership Project is called for short " 3GPP ") agreement has all defined the protocol interface message of various flow processs and standard on each open interface.According to this agreement, if catastrophe failure takes place for network side, for example CN breaks down, initiate to reset to RNC, the perhaps veneer exceptional reset of RNC management resource, the calling that causes relating to this kind resource need discharge etc., has the ample resources requirement in the short time to discharge, and this moment, dispose procedure often related to many users and resource.If release may cause interior system loading of short time to reach peak value continuously, thereby causes the stability of a system to descend.

Therefore, the general at present scheme that adopts level and smooth release.The level and smooth mode that affected resource employing is discharged in batches that is meant that discharges for example discharges 20 examples earlier, waits one second and discharges following 20 examples later on again.Avoided the stability of the system that influences because of the instantaneous rising of load of system thus.

In level and smooth release, exemplary message is exactly a reset message, i.e. " RESET ", with the Iu interface is example, description according to 3GPP 25.413 agreements, when fault that the transmission index information loses takes place in CN, as shown in Figure 3, CN will initiate the RESET message of the corresponding domain of Iu interface, and UTRAN receives after " RESET " message, will initiate affected RAB (Radio Access Bearer, abbreviation " RAB ") dispose procedure, will initiate the dispose procedure of the RAB in entire circuit exchange (Circuit Switching is called for short " CS ") territory or whole group exchange (Packet Switching is called for short " PS ") territory like this.For the processing of this class message, can adopt the level and smooth in batches method that discharges.

Yet, though above-mentioned this mode has avoided the stability of system to be affected, may have new calling in the level and smooth gap that discharges of example and insert, might cause the new calling that inserts to be released i.e. " call loss ".

Need to travel through resource in this case.Specifically, promptly the affected resource of the current failure message of mark makes a distinction affected resource and the new resource that inserts.

In actual applications, there is following problem in such scheme: because the often affected example of this class fault is a lot, adopt the traversal mark to realize that the level and smooth mode that discharges can expend the more time, especially all kinds of faults are intersected when taking place, can cause the ergodic process performance low, the dispose procedure low-response, thus the speed that system flow is handled influenced.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of method that resource discharges of carrying out, and makes and further improves the level and smooth speed that discharges, and guarantees the good operation of system.

For achieving the above object, the invention provides a kind of method that resource discharges of carrying out, comprise following steps:

A produces and the corresponding failure sequence number of all kinds of faults of maintenance system, and the failure sequence of every class fault number increases progressively according to the number of times that this fault takes place;

B is the current failure sequence of the example relevant with fault described fault when writing down this example application number;

C is when breaking down in the system and need level and smooth release, the current failure sequence of this type of fault number when relatively causing the corresponding failure sequence number of the level and smooth fault that discharges and example application, if the current failure sequence of the corresponding failure sequence number that causes the level and smooth fault that discharges this type of fault during number more than or equal to the example application, then described example is smoothly discharged, otherwise, described example is not smoothly discharged.

Wherein, in the described steps A, the increment value of described failure sequence number is 1.

In described step C, phylogenetic fault is outside unusual.

In described step C, phylogenetic fault is the internal fault of communication equipment.

By relatively finding, technical scheme difference with the prior art of the present invention is, in the level and smooth release that the system failure causes, write down the corresponding failure sequence number of each fault, and when needs smoothly discharge, judge the surrounding time relation of the current failure sequence number of corresponding failure sequence number this type of fault during cause the level and smooth fault that discharges, thereby distinguish the calling that needs the example that discharges and new access with the example application.

Difference on this technical scheme has brought comparatively significantly beneficial effect, promptly by avoiding traversal

Difference on this technical scheme has brought comparatively significantly beneficial effect, promptly by avoiding traveling through the process of each example, has saved a large amount of time, has improved the speed that system flow is handled.

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.

It may be noted that at first principle of the present invention is to have increased a sequence number, be called " failure sequence number ".And in system's running, produce and safeguard this failure sequence number.Specifically, for a class fault, corresponding failure sequence number is arranged, when this fault took place in system, the failure sequence of this type of fault number just increased by 1.

When the example application relevant with an above-mentioned class fault takes place, the current failure sequence of this a class fault attribute number is as an example preserved being called of this attribute " InstSn ".This attribute can show that this type of fault is which time takes place in the example application.

Above-mentioned failure sequence number has been arranged, being equivalent to has increased a timetable for system and example, this timetable is noted till the example application, and this type of fault of how many times has taken place altogether in the system, and applies for after which time fault takes place for this example under the example application record.

When system breaks down need smoothly discharge the time, the corresponding failure sequence of the moment number of this fault: Sn takes place in system log (SYSLOG).When smoothly discharging each time, all earlier the attribute InstSn in Sn and each example is compared.

Because as mentioned above, for the corresponding sequence number of a class fault, be along with each time increase progressively 1, therefore, when corresponding failure sequence Sn is more than or equal to some example applications when this fault takes place during the current failure sequence InstSn of this type of fault, the application time that this example is described needs the level and smooth fault that discharges early than this, so this example need discharge.On the other hand, when corresponding failure sequence Sn was less than above-mentioned example application when if this fault took place during the current failure sequence InstSn of this type of fault, this application time that shows example is in the back of the level and smooth fault that discharges of these needs, so this example does not need to discharge.

Below with reference to Fig. 4, the level and smooth method for releasing according to the first embodiment of the present invention is described.In the present embodiment, smoothly discharge by outside exception-triggered, specifically, in the WCDMA system, core net issues Iu interface " RESET " message, and this message will cause radio network controller that affected user is smoothly discharged.In the present embodiment, have 2000 users to need to discharge, if smoothly discharge 500 each second, finishing whole dispose procedure needed for 4 seconds.On the other hand, under normal circumstances can insert 20 callings each second, this had 80 and calls out access in level and smooth 4 seconds that discharge.If affected calling is not traveled through, distinguish level and smooth calling that discharges of actual needs and the new calling that inserts, this may cause 80 new calling call drops in 4 seconds.But, smoothly discharge if distinguish then by the traversal mode, need all customer instances of traversal, when the radio network controller duty ratio is higher, 50000 examples are for example arranged, this need mark 2000 affected examples in these examples, as seen need expend the plenty of time.Method according to the level and smooth release of first embodiment of the present invention embodiment comprises following steps:

At first in step 100: whenever breaking down, system produces and safeguards the failure sequence Sn of this fault.In the present invention, for each class fault corresponding failure sequence Sn is arranged all, when this fault took place in system, the failure sequence Sn of this type of fault just increased by 1.Certainly, in other embodiments of the invention, the incremental value of failure sequence Sn can be selected as required.This failure sequence Sn is kept in the system.

After this enter step 200, when the example application relevant with some faults takes place in system, the current failure sequence InstSn of this fault when writing down described example application.Specifically, when the example application relevant with fault took place, system preserved a current failure sequence InstSn attribute as an example of this class fault get off, and this attribute can show that this type of fault is which time takes place in the example application.As mentioned above, current failure sequence InstSn during by failure sequence Sn and example application, can show till the example application, this type of fault of how many times has taken place altogether in the system, and show that the example application applies for after which time fault takes place.

Step 300, when needing level and smooth release owing to fault, the current failure sequence InstSn of system during to the corresponding failure sequence Sn of described fault and each example application compares, if the corresponding failure sequence Sn of described fault is current failure sequence InstSn during more than or equal to the example application, then described example is smoothly discharged, otherwise described example is not smoothly discharged.In this step, because as mentioned above, the failure sequence of each class fault number is that the increase along with frequency increases progressively successively, therefore pass through the comparison of two failure sequence Sn and InstSn, when current failure sequence InstSn during less than the example application of the failure sequence Sn of the fault that causes level and smooth release, the application time that this example is described is later than the fault that this time needs level and smooth release, therefore enters step 400, promptly this example is not discharged.On the other hand, if the failure sequence Sn of fault that causes level and smooth release is current failure sequence InstSn during more than or equal to the example application, therefore this application time that shows example enters step 500 in the front of the level and smooth fault that discharges of these needs, and this example is smoothly discharged.

In the present embodiment, the failure sequence Sn of the fault by in dispose procedure, relatively causing level and smooth release, current failure sequence InstSn during with the example application, the calling of distinguishing the new calling that inserts effectively and originally needing to discharge neither causes call loss also not need traversal.

In second embodiment of the present invention, the level and smooth internal fault that is taken place by general device that discharges causes.Specifically,, all be equipped with a veneer that is exclusively used in management resource, be similar to a resource pool such as RNC, CN and subscriber equipment general communication equipments such as (User Equipment are called for short " UE ").In addition, the distribution of resource is used, and the processing of signaling process is then realized by another kind of veneer.When the veneer of management resource is unusual, cause using in a large number the calling of this veneer resource to be affected, these callings need to discharge.In dispose procedure, can occur with above-mentioned first embodiment in similar problem.Because the kind of resource is a lot, therefore the example quantity that relates to is big, in this case, also is fit to adopt the described failure sequence mode of first embodiment smoothly to discharge.Because flow process with above the same, therefore no longer is repeated in this description herein.

Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
