Embodiment
Embodiments of the invention provide a kind of fault detection method of the network equipment, the hardware resource that unusual place, the sub-district network equipment occurs is sorted according to call successful rate, obtain the minimum hardware resource of call successful rate in this network equipment according to ranking results, if the hardware resource that this call successful rate is minimum satisfies the hardware resource alarm conditions of this network equipment, judge that then this hardware resource breaks down.
Because the traffic load that of a sort hardware is born in the communication equipment all is the same, can't distinguish when breaking down.So in an embodiment of the present invention, in order to distinguish these hardware, can be when setting up equipment each the piece veneer in each network equipment, the network equipment and even each module or element all be numbered, when equipment breaks down, can number and specifically navigate to veneer, module or the element that breaks down by these by equipment supplier or equipment operator.Because veneer, module or element use as resource in communication, so in an embodiment of the present invention it is referred to as hardware resource.For example, each piece veneer in the equipment and the DSP in the veneer are all carried out serial number, different numberings just corresponding specific veneer or DSP.These hardware resource numberings in each equipment can be carried out record with specific parameter, with the WCDMA system is example, the numbering of hardware resource in the radio network controller (RNC) is represented with CRNCID, the numbering of hardware resource represents that with NBCCID CRNCID and NBCCID are the parameter in the agreement in the base station (NodeB).In like manner, in other communication systems such as GSM, CDMA, also can be numbered its hardware resource, for example, in cdma system, the numbering of hardware resource among the BSC (base station controller) can be represented with BSCID that the numbering of hardware resource is represented with BTSID among the BTS (base station).Below just illustrate, when realizing, can define relevant parameter according to concrete agreement.
Be example with the WCDMA system below, concrete coding rule be introduced that the coding rule in the other system can the rest may be inferred.
CRNCID different in the WCDMA system are according to different hardware resource unit among the corresponding RNC of coding rule, and when the numbering of hardware resource only was sub-divided into veneer, then CRNCID can be expressed as: CRNCID=veneer ID (8bits);
This moment, CRNCID just represented veneer ID, and for example: when the value of CRNCID is 2, then represent the 2nd veneer in this RNC equipment, the user can be provided with CRNCID as required.
When the numbering to hardware resource is sub-divided into the DSP of each veneer use, then: CRNCID=veneer ID+DSPID;
Take a byte respectively such as veneer ID and DSPID, when veneer ID is 2, DSPID is 1 o'clock, then first DSP on the 2nd veneer in this this RNC equipment of sign expression.
For convenient other module or device in the equipment detected, also can when being set, CRNCID reserve a byte or a plurality of byte, be generally CRNCID in the agreement and reserve 4 bytes, can make up voluntarily as required and define, for example: CRNCID=veneer ID+DSPID+Reserve;
Above-mentioned Reserve is one or more bytes of reservation, can be used for representing the numbering of other devices or module, when RNC detects the CRNCID that breaks down in running, then can navigate to certain the concrete device or the module of CRNCID correspondence.
More than to the just explanation for example of the coding rule of CRNCID, when specific implementation, be not limited to above-mentioned coding rule.
NodeB is similar to the coding rule of CRNCID to coding rule and the RNC of NBCCID, different hardware resource unit among the corresponding NodeB of different NBCCID, and when the numbering to hardware resource only was sub-divided into veneer, NBCCID can be expressed as: NBCCID=veneer ID;
Be up or descending branch the, the then up veneer ID+ of NBCCID=downlink board ID according to the data of handling perhaps with veneer.
When the numbering to hardware resource is sub-divided into the DSP of each veneer use, NBCCID=veneer ID+DSPID;
Be up or descending branch the, the then descending DSPID of the up veneer ID+ of NBCCID=up DSPID+ downlink board ID+ according to the data of handling perhaps with veneer.
Also can when CRNCID is set, reserve a byte or two bytes, be used for other module or device of equipment detected, reserved byte be represented with Reserve, for example: NBCCID=veneer ID+DSPID+Reserve herein;
It is up or descending branches according to the data of handling perhaps with veneer, hardware resource numbering to uplink and downlink is reserved one or more bytes respectively, the byte that the upstream hardware resource number is reserved is represented with Up_Reserve, the byte that descending hardware resource numbering is reserved is represented with Down_Reserve, also can be defined the byte-sized of Up_Reserve and Down_Reserve in actual applications as required voluntarily.Be sub-divided into the DSP that each veneer uses with numbering and be example, then the descending DSPID+Down_Reserve of the up veneer ID+ of NBCCID=up DSPID+Up_Reserve+ downlink board ID+ hardware resource.
Each numbering can be provided with according to demand with how many position or how many byte representations among the NBCCID.
Since in each system to the numbering of hardware resource all similarly, so introduce for convenience, below we will be called base station IDs to the numbering unification of hardware resource in the base station, numbering unification to hardware resource in base station controller or the radio network controller is called base station controller ID, the numbering of veneer is veneer ID, and the numbering of DSP is called DSPID etc.Fig. 1 is the flow chart that a pair of hardware resource of the embodiment of the invention carries out fault detect, and in the present embodiment, being sub-divided into veneer with the numbering to hardware resource is example, and concrete steps are as follows:
Step 101: when default time period or preset period arrival, judge whether the sub-district occurs unusually.
Judge herein whether the sub-district occurs a variety of methods are arranged unusually, for example judge that whether the cutting off rate of sub-district satisfies default cutting off rate alarm conditions, if satisfy default cutting off rate alarm conditions then to judge that the sub-district occurs unusual.Cutting off rate alarm conditions herein can be provided with according to the concrete condition of sub-district by operator or equipment manufacturers, such as CS (Circuit Switch with the sub-district, circuit commutative field) cutting off rate is set to alarm conditions greater than A% or PS (Packet Switch, packet-switched domain) cutting off rate greater than B%; For not only support circuit-switched territory but also support the system of packet-switched domain, the CS cutting off rate of sub-district is set to alarm conditions greater than A% and PS cutting off rate greater than B%; Perhaps the difference with cutting off rate between the different districts of same base station reaches more than the C%, and perhaps the cutting off rate of this sub-district is set to alarm conditions with comparing for the previous period to have raise more than the D%.Or whether the position turnover rate of judging the sub-district is less than default threshold value, if it is unusual to judge that then the sub-district occurs.In like manner, whether some other traffic statistics index as the sub-district unusual basis for estimation can also be appearred.Whether satisfy the sub-district alarm conditions with the sub-district cutting off rate among Fig. 1 and judge whether the sub-district occurs unusually.
In addition, because the embodiment of the invention is the problem that the hardware that specifically breaks down occurs how detecting when unusual in the sub-district in order to solve, so how to judge that it is not the emphasis of the embodiment of the invention unusually that the sub-district occurs, promptly remove step 101, do not influence the realization of embodiment of the invention method.
In this step,, then according to actual needs, perhaps finish this detection, perhaps next sub-district execution in step 101 is detected if it is unusual to judge that the sub-district does not occur.If it is unusual to judge that the sub-district occurs, then execution in step 102.
Step 102: the hardware resource under the same base station that unusual place, sub-district occurs is sorted according to call successful rate.
Since in equipment running process, the situation of the site number of base station controller records per call (SiteID), cell id (CellID), base station IDs, base station controller ID and access success or failure, and preserve.So when alarm appears in certain sub-district, can find the base station of this sub-district correspondence according to the site number of sub-district correspondence easily, the call case of this base station all has corresponding record in base station controller, and each bar record is that base station IDs is corresponding with its hardware resource numbering all.
For example: when the numbering to hardware resource refine to veneer, coding rule according to above-mentioned introduction, then base station IDs is veneer ID, base station IDs is sorted according to call successful rate herein, then is equivalent to the call successful rate that veneer under the unusual same base station, place, sub-district occurs is sorted.Above-mentioned ordering is also unrestricted, can be from high to low, and also can be from low to high.
Step 103: according to ranking results, find the minimum hardware resource of call successful rate in the base station, judge whether the call successful rate of this hardware resource satisfies the BTS hardware alarm conditions.
BTS hardware alarm conditions herein can be provided with according to demand by the user, for example: the difference of the call successful rate of the hardware resource that hardware resource that call successful rate is minimum and call successful rate are the highest is set to the BTS hardware alarm conditions, if the hardware resource that the minimum hardware resource of call successful rate and call successful rate are the highest is compared, when its call successful rate difference is higher than default threshold value, perhaps, the call successful rate of hardware resource is lower than default threshold value, judges that then the call successful rate of this hardware resource satisfies the BTS hardware alarm conditions.
In this step,, then according to actual needs, perhaps finish this detection, perhaps next sub-district execution in step 101 is detected if do not satisfy alarm conditions.If satisfy alarm conditions, then execution in step 104.
Step 104: to base station controller report and alarm information.
Comprise ID number of the hardware resource that call successful rate is minimum in the above-mentioned warning information, for example veneer ID, DSPID etc. are veneer ID in the present embodiment.To base station controller report and alarm information, can point out user's obturation or replacing to satisfy pre-conditioned hardware resource.
Under the another kind of scene,, then can also further detect the hardware resource in the base station controller if in step 103, do not find out the hardware resource that satisfies the BTS hardware alarm conditions.If promptly the hardware resource that the hardware resource that call successful rate is minimum in the step 103 and call successful rate are the highest is compared, when its call successful rate difference is lower than default threshold value, perhaps the call successful rate of this hardware resource is higher than predetermined threshold value, and the hardware resource that then enters in the step 105 pair base station controller detects.
Step 105: base station controller sorts according to call successful rate to the hardware resource of base station controller.
For example, when the numbering to the hardware resource of base station controller refine to veneer, coding rule according to above-mentioned introduction, base station controller ID is veneer ID, hardware resource to base station controller sorts according to call successful rate, then is equivalent to the veneer in this base station controller is sorted by call successful rate.This ordering and unrestricted can be from high to low, also can be from low to high.
Step 106: find the minimum hardware resource of call successful rate in the base station controller according to ranking results, whether the call successful rate of judging this hardware resource satisfies base station controller hardware alarm condition, and if satisfied execution in step 104 to base station controller report and alarm information; Otherwise, finish this and detect, perhaps according to the needs of actual conditions, change step 101 pair next sub-district over to and detect.
Base station controller hardware alarm condition herein can be provided with according to demand, for example: the difference of the call successful rate of the hardware resource that hardware resource that call successful rate is minimum and call successful rate are the highest is set to base station controller hardware alarm condition, if the hardware resource that the minimum hardware resource of call successful rate and call successful rate are the highest is compared, when its call successful rate difference is higher than default threshold value, then, point out user's obturation or change the minimum hardware resource of this call successful rate to base station controller report and alarm information.
Comprise ID number of the hardware resource that call successful rate is minimum in the above-mentioned warning information, for example, veneer ID or DSPID etc.Because each hardware resource all has its corresponding ID number, so can find the hardware resource that breaks down soon according to ID number of hardware resource in the warning information.
Because the hardware resource that has in the base station is used for up call, what have is used for downlink call, so when the hardware resource fault of base stations detected, all detect respectively usually according to upstream hardware resource and descending hardware resource, based on this prerequisite, the present invention proposes second embodiment, as shown in Figure 2, the part that second embodiment is different with first embodiment only is the detection mode of the hardware resource of base station not quite alike, therefore identical with first embodiment part no longer describes in detail in the present embodiment, with upstream hardware resource in the first base stations detected, the order that descending hardware resource is detected in the back is an example, and the flow process to embodiment two is elaborated below.
Step 201: with step 101, when default time period or preset period arrival, base station controller judges whether the sub-district occurs unusually; If, execution in step 202A then; If not, then finish this and detect, perhaps according to the needs of actual conditions, execution in step 201 begins next sub-district is detected.
In addition, because the embodiment of the invention is the problem that the hardware that specifically breaks down occurs how detecting when unusual in the sub-district in order to solve, so how to judge that it is not the emphasis of the embodiment of the invention unusually that the sub-district occurs, promptly remove step 201, do not influence the realization of embodiment of the invention method.
Step 202A: base station controller sorts according to call successful rate to the base station IDs of upstream hardware resource correspondence under the same base station that unusual place, sub-district occurs.
Step 202B: find the upstream hardware resource that call successful rate is minimum in the base station according to ranking results, whether the call successful rate of judging this upstream hardware resource satisfies base station upstream hardware resource alarm condition, if satisfy alarm conditions then to base station controller report and alarm information, otherwise, change step 203A over to.
Step 203A: base station controller sorts according to call successful rate to the base station IDs of the descending hardware resource correspondence of same base station that unusual place, sub-district occurs.
Step 203B: find the minimum descending hardware resource of call successful rate in the base station according to ranking results, whether the call successful rate of judging this descending hardware resource satisfies base station down hardware resource alarm conditions, if satisfy then execution in step 204, otherwise, finish this detection, perhaps, change step 201 pair next sub-district over to and detect according to the needs of actual conditions.
Step 204: to base station controller report and alarm information.
If in step 203B, do not find out the hardware resource that satisfies alarm conditions, then can also further detect the hardware resource in the base station controller, promptly change step 205 over to.
Step 205: base station controller sorts according to call successful rate to base station controller ID.
Step 206: whether the call successful rate of judging the hardware resource that call successful rate is minimum in the base station controller satisfies base station controller hardware alarm condition, if satisfy base station controller hardware alarm condition then to base station controller report and alarm information, otherwise, finish this detection, perhaps, change step 201 pair next sub-district over to and detect according to the needs of actual conditions.
Comprise ID number of the hardware resource that call successful rate is minimum in the above-mentioned warning information, for example, veneer ID or DSPID etc.Because each hardware resource all has its corresponding ID number, so can find the hardware resource that breaks down soon according to ID number of hardware resource in the warning information.Thereby realized when network equipment operation appearance is unusual, can finding the hardware that specifically breaks down rapidly, improved the efficient of fault location, reduced operation cost.
When in the present embodiment the hardware resource of base station being detected, be according to detecting the order that the upstream hardware resource detects descending hardware resource more earlier, and when practical application, also can detect the upstream hardware resource again according to detecting descending hardware resource earlier, its flow process is similar to the flow process of describing among the embodiment two, so be not described in detail in this.
