Embodiment
Core concept of the present invention is: by phase-split network user's call information, find out because the wireless environment call drop record that causes of poor quality, determine the zone at the preceding place of conversation loss according to the pilot tone in the Active Set before the conversation loss in the call information, cause the zone of conversation loss to carry out statistical analysis to these owing to the wireless environment difference again, thereby orient the weak overlay area of wireless environment difference.
Based on above-mentioned thought, as shown in Figure 1, adopt following technical scheme in the embodiment of the invention:
Step 1, all users' call information in the record wireless network comprises at least in this call information that terminal discharges the pilot tone of preceding Active Set, pilot frequency intensity and calls out release cause;
Record comprises that normal talking record and call drop are recorded in interior all-calls information herein, can screen out the call drop record according to calling out release cause from call information.Alternatively, can also be included in last four handover informations of terminal in the communication process in this call information, comprise the pilot tone and the pilot frequency intensity of terminal Active Set, Candidate Set in the handover information.
Step 2 is classified to the wireless network user call information of record, finds out because the call drop record that wireless environment poor signal quality (being poor signal quality) causes;
Wherein, just can determine in conjunction with pilot frequency intensity whether call drop is because due to the wireless environment poor signal quality again according to calling out release cause.
Step 3, terminal discharges the pilot tone of preceding Active Set in the call drop record of determining to find, and determines the sub-district at the preceding place of customer call call drop again according to the pilot tone of Active Set;
Step 4, at determined sub-district, carry out statistical analysis according to the pilot frequency intensity of this sub-district in Active Set before the terminal call drop, and find weak overlay area in the network according to statistics, and wireless environment situation that should the zone, promptly the wireless signal of which sub-district emission, the power that each sub-district transmits etc. can both be received in this zone.
Wherein, the concrete steps of adding up according to pilot frequency intensity are as follows:
1, to each time because the wireless environment difference causes the record of call drop, according to the pilot frequency intensity ordering of sub-district in the Active Set before the call drop, the contribution of calling being kept according to the pilot tone power, the sub-district that pilot frequency intensity is strong comes the front, and the weak sub-district of pilot frequency intensity comes the back;
2, according to the cell combination after the ordering, the combination that the number of dropped calls of adding up every kind of combination, number of dropped calls are many more, the sub-district that this combination relates to is big more to weak covering call drop influence.For example cause the record of call drop to be added up to 100 wireless environment differences, (A, B) combination of the call drop of two sub-districts accounts for 80 times altogether, so just can determine that the borderline region wireless environment of A, two cell coverage areas of B is poor, exists the weak possibility that covers very big.
Weak overlay area described herein is meant the zone that wireless environment is poor, the general easy terminal call drop in communication process that causes in weak overlay area.It should be noted that weak covering might not all be because due to signal do not cover, the phase mutual interference before each cell signal also caused weak covering easily.
Above-mentioned statistics is assessed, just can confirm further that weak overlay area is owing to the weak covering that weak covering, radio-frequency power that weak covering, pilot pollution that the isolated island station causes cause cause, the reasons such as weak covering that indoor turning causes, and provides strong support to the radio signal quality of optimizing weak overlay area.
For example to 100 times since the call drop record that the wireless environment quality problems cause add up, if there is and has only the call drop record of A sub-district to exceed predetermined threshold (for example above 80 times) in the Active Set, can infer that so this zone is that the isolated island station covers, because the border of this sub-district does not have other sub-district to cover, when causing terminal to move to the border of this sub-district, because poor signal quality causes call drop.
If to 100 times since the call drop record that the wireless environment quality problems cause add up, a plurality of call drop cell combination appear in statistics, and the shared ratio of each combination is not again very big, for example, cell combination (A, B), (B, C) and (A, C) shared ratio quite (promptly about equally), can infer that so this zone is the pilot pollution district, this zone is covered by a plurality of sub-districts, but the signal of each coverage cell is all more weak again in this zone, cause terminal in communication process because signal quality problem call drop.
If to 100 times since the call drop record that the wireless environment quality problems cause add up, in the statistics, there is strong pilot tone (even if it is generally acknowledged that pilot frequency intensity is greater than-strong the pilot tone of 13db) before the call drop in the Active Set, but Active Set does not have strong pilot tone during call drop, can infer so in this zone (cell coverage area when referring to discharge in the Active Set) to have elevator or indoor turning.Wherein, owing to preserved repeatedly handover information in the call drop record, each handover information all has Active Set pilot tone and pilot frequency intensity, and Active Set is meant the Active Set in the last handover information during described call drop; Active Set before the described call drop is meant the Active Set in the last handover information handover information of preserving in the call drop record before.
Cause the processing mode of weak covering problem also different for a variety of causes, for the weak covering that the isolated island station produces, the transmitting power or the consideration that need to improve the base station add the station; For the weak covering that pilot pollution causes, need to adjust the coverage of peripheral base station, guarantee that there is one to two strong pilot tone in this zone; For elevator or indoor corner region, for example the user is in that to enter the elevator front signal relatively good, enters behind the elevator because the elevator shielding, and signal quality declines fast, causes call drop, then can consider to increase indoor covering.
As shown in Figure 2, the device of weak overlay area comprises in the fixer network of the embodiment of the invention: call information logging modle and statistical analysis module, wherein,
The call information logging modle is used for, and writes down the call information of all users in the wireless network and sends to statistical analysis module, wherein, comprises at least in the call information that user terminal discharges the pilot tone of preceding Active Set, pilot frequency intensity and calls out release cause;

Further, statistical analysis module is used for, and determines in the following way in the call information because the wireless environment call drop record that causes of poor quality:
Therefrom screen out the call drop record according to the calling release cause in the call information;
Determine that in conjunction with pilot frequency intensity the call drop record that is screened out is to cause owing to wireless environment is of poor quality.
