Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to a kind of defining method of fault network element device, device and equipment.
Background technology
In moving communicating field, the Key Performance Indicator (KPI, Key Performance Indicators) measuring various communication network is the important means weighing this communication network quality quality always.Along with the development of the communications industry, whole industry more and more pays close attention to the communication network quality of user awareness for the management of communication network quality, and then proposes communication network Key Quality Indicator (KQI, Key QualityIndicators).But be that KPI index or KQI index all exist a defect, i.e. the average quality being communication network of their reflections, when weighing different communication networks, average quality is extraordinary judgment criteria.But for the technical staff of the intrinsic communication network of maintenance optimization, except the communication network average quality represented in the COMMUNICATION NETWORK PERFORMANCES lifting phase continues to rise, or outside fluctuating widely when significant trouble appears in communication network, stable period is kept at communication network quality, the use value of the average quality of communication network will significantly reduce, especially present communication network, through constantly optimizing, has been in the period that quality is higher and relatively highly stable.
Communication network quality particularly for user awareness manages, average quality is adopted to weigh again, its defect is apparent, such as, for the communication network having 10000 users, wherein the percept of call completed of 9999 users is 100%, and only have the percept of call completed of 1 user to be 0%, if employing average quality, the percept of call completed that will obtain whole network is the average result of 99.99%, on the surface, the average quality of percept of call completed is really very high, but be the user of 0% for that percept of call completed, it is extreme difference that its network is experienced, but but can not be reflected exactly.
For the quality management of calling network, whether whether its percept of call completed up to standard has problems with network is the judge means of two independently network qualities, if whether only adopt average quality to weigh percept of call completed up to standard, can not reflect Problems existing in network truely and accurately, this is for especially obvious the higher and highly stable network of quality.Illustrate at this, as shown in table 1:
Table 1
| Number of call attempts | Connect number of times | Percept of call completed | The frequency of failure | |
| Period 1 | 500000 | 480000 | 96% | 20000 |
| Period 2 | 500000 | 478000 | 95.6% | 22000 |
| Fluctuating range | -0.4% | 10% |
As can be seen here, be the network of 96% for a percept of call completed, when the fluctuating range of percept of call completed is 0.4%, its percept of call completed still keeps a very high quality, but the frequency of failure but adds 2000 times, amplitude of variation also reaches 10%, and only adopts average quality cannot reflect 2000 frequency of failures of increase truely and accurately at all.Comprise
So, for the call quality of network, weigh by means of only percept of call completed in prior art, can only reflect that whether call quality is up to standard from entirety, especially for the network that quality is higher and highly stable, call quality substantially all maintains higher level, thus can be in state up to standard always.But, now cause increase and the fluctuation of call failure number of times due to the fluctuation in network, adopt prior art means to determine exactly.

Further, TCH is distributed into power determining method as the formula (10):
TCH is distributed into power=voice channel and takies number of times (not containing switching)/voice channel number of call attempts (not containing switching) formula (10)
Wherein, TCH is distributed into power mainly for detection of BSC equipment is the success rate that user distributes voice channel.Voice channel number of call attempts can be sent by BSC assigns the number of times of order (Assignment Command) message add up, and voice channel takies appointment that number of times can be received by BSC equipment and completes (Assignment Complete) number and add up.
Further, SDCCH is distributed into power determining method as the formula (11):
SDCCH is distributed into power=SDCCH and distributes number of times/SDCCH distribution number of call attempts formula (11)
Wherein, SDCCH is distributed into power mainly for detection of BSC equipment for before user distributes voice channel, for user distributes the success rate of SDCCH channel.

Wherein, RRC connection establishment success rate is the success rate that user sets up RRC connection mainly for detection of RNC.
Further, RAB (RAB, Radio Access Bearer) is distributed into power determining method as the formula (13):
RAB is distributed into power=(the circuit domain conversation class 12.2K RAB number of circuit domain conversation class narrowband self-adaption multi-speed (AMR, Adaptive Multi-Rate) RAB number+success foundation that success is set up)/(asking the circuit domain conversation class 12.2KRAB number that the circuit domain conversation class arrowband AMR RAB number+request of setting up is set up) formula (13)
Further, RAB be distributed into power be mainly used in check RNC be the success rate that user distributes RAB.The RAB that molecule in formula (13) can be received by RNC has assigned assignmentcomplete(RAB) message number adds up, the RABassignment request(RAB assignment request that denominator can be received by RNC) message number adds up.
S203, determine the desired value fluctuating range of the These parameters that the first network element device is corresponding.
Further, in this step, multiple time period to be compared can be specified, and by the desired value of These parameters corresponding for the first network element device in the time period to be compared being subtracted each other respectively, determine the desired value fluctuating range of the These parameters that the first network element device is corresponding.
S204, from the first network element device, determine that the desired value fluctuating range of corresponding any index is greater than the second network element device of default fluctuating range.
In this step, when in the first network element device, in the desired value of each index above-mentioned of certain the first network element device, when the fluctuating range that there is arbitrary desired value is greater than default fluctuating range, this first network element device is defined as the second network element device.
Further, default fluctuating range can be arranged according to actual needs.
