The probability of each cause parameter；Wherein, described paging black hole event Producing reason parameter includes: PCH
Channel resource is not enough, SDCCH channel resource is not enough and wireless coverage cause parameter.
Specifically, the process that paging does not responds can be decomposed into following Four processes:
Process1: paging command (paging Command) process, this process is that BSC order BTS exists
In its community, paging is called.The failure cause of this process is that paging channel resource deficiency (is designated as
CAUSE1).If in ABIS interface signaling data, the last BTS before the event time of paging black hole
Send CCCH load indication message instruction paging channel resource to BSC not enough, be then paging resource
The paging that anxiety causes is not responded.The number of times COUNT1 that statistics CAUSE1 occurs.
Process2:BTS paging is called, called access BTS process.
This procedure failure reason is wireless coverage reason (being designated as CAUSE2).The failure of this process signaling by
In being not reflected in ABIS interface signaling process, therefore its number of times cannot be added up.
Process3:SDCCH channel sets up process, if SDCCH channel sets up unsuccessfully (Channel
Activation Negative ACKnowledge message indicates) and set up failure cause and be: Radio link
The number of times of failure or Radio interface failure, then be the paging black hole non-wireless coverage of business reasons
Reason causes (being designated as CAUSE2)；
If there is Channel Required message and Immediate assignment reject message occurs
Signaling process then paging black hole business reasons is that SDCCH channel is not enough (CAUSE3).It is right to add up respectively
The number of times COUNT3 answered.
Process4: set up instruction process.
SDCCH arrives the process between Paging Response message after setting up, and this procedure failure is also
It is that wireless coverage reason causes (being designated as CAUSE2).
Wherein, after above-mentioned analysis, wireless coverage reason COUNT2=total degree-(COUNT1+
COUNT3), wherein, COUNT1 is the number of times that paging channel resource is not enough, and COUNT3 is SDCCH
The number of times that channel is not enough.
Called subscriber's flow process by the analysis to ABIS signaling test data, and can be carried out by the i.e. present invention
Statistics such that it is able to accurately obtain the probability weight of each reason that paging black hole produces.
Step 607: obtain the proportion of each cause parameter in wireless coverage cause parameter, including:
After the state event location of paging black hole, thus, each paging black hole, user place community of not responding
Network event just can determine, and the signaling process that so this network event is corresponding can be obtained by, and enters
One step obtains the measurement report message in signaling process.
Wherein, specifically, the measurement report message of described ABIS interface includes: user terminal measurement
Descending level and quality, BTS measure upper line level and quality.
Wherein, in order to paging black hole cause parameter is precisely located out, need to set a relative threshold,
And utilize this relative threshold entry value each with the measurement in measurement report to compare, thus it is accurately positioned out black
The a variety of causes in hole, specifically, refer to descending level in wireless coverage cause parameter, downlink quality,
Upper line level and up execution ratio in total wireless coverage cause parameter.
Such as, downlink electrical Plain is because the paging black hole ratio=downlink electrical Plain produced is because of weight/(descending level
Reason weight+downlink quality reason weight+downlink quality reason weight+up cause for quality weight).
In one embodiment, above-mentioned relative threshold is set to: downlink electrical jib door is limited to-85dBm, descending matter
Amount level threshold is 6, and up level threshold is-100dBm, and up quality threshold is 6.
Step 608: position the possibility that in a paging black hole event, every kind of reason accounts in community, paging black hole
Property proportion, specifically includes:
Obtain the weight of the generation paging black hole each reason of event and each in generation wireless network covering reason
Plant the weight of cause parameter；
Every kind of cause parameter is obtained in a paging black hole event in community, paging black hole according to above-mentioned information
The probability proportion accounted for, according to the result obtained in above-mentioned steps, such as, in step 606, it obtains
The weight of the paging black hole each cause parameter of event gone out is as follows:
PCH channel resource deficiency reason proportion COUNT1:EVENT_W1=CAUSE1/ no-response paging number of times；
SDCCH channel resource deficiency reason proportion COUNT3:EVENT_W3=CAUSE3/ no-response paging number of times；
Wireless coverage reason proportion COUNT2:EVENT_W2=1-EVENT_W1-EVENT_W3.
In step 608, its weight of each reason in wireless coverage reason obtained is as follows:
Downlink electrical Plain is because of weight: EVENT_W2-1=EVENT_W2*DL_LEVEL_COUNT/SUM；
Downlink quality reason weight: EVENT_W2-2=EVENT_W2*DL_RXQUAL_COUNT/SUM；
Upper line level reason weight: EVENT_W2-3=EVENT_W2*UL_LEVEL_COUNT/SUM；
Up cause for quality weight: EVENT_W2-4=EVENT_W2*UL_RXQUAL_COUNT/SUM.
Wherein, described DL_LEVEL_COUNT: descending level is less than thresholding measurement report number of times；
DL_RXQUAL_COUNT: descending level is less than thresholding measurement report number of times；
UL_LEVEL_COUNT: upper line level is less than thresholding measurement report number of times；
UL_RXQUAL_COUNT: upper line level is less than thresholding measurement report number of times；
And SUM=DL_LEVEL_COUNT+DL_RXQUAL_COUNT+UL_LEVEL_COUNT+
UL_RXQUAL_COUNT。
Step 609: the probability proportion of every kind of cause parameter in the event of statistics all of black hole, community, black hole；
The distribution situation of paging black hole producing cause parameter in community, black hole is obtained according to above-mentioned statistics.
According to above-described embodiment, dividing of the paging black hole producing cause parameter of some community finally given
Cloth situation is as follows:
