Fig. 1 shows a kind of process signal of the cell positioning method of communication network handover failure in the embodiment of the present invention
Figure.As shown in Figure 1, the cell positioning method mainly may comprise steps of:
Step S11: the measurement report sample data MRO that the UE of predetermined period is reported is obtained.
Step S12: parsing MRO, obtain a communication information record corresponding to each MR in MRO.
It, can be logical by one corresponding to each MR in parsing MRO, the MRO got in the embodiment of the present invention
Letter information records, the net of evolved universal terrestrial radio access network cell ID ECI, user terminal in every communication information record
Network node unique identification MmeUeS1apId, time stamp T imeStamp, LTE serving cell Reference Signal Received Power
The adjacent area MR.LteScRSRP and GSM carrier received signal intensity indicates MR.GsmNcellCarrierRSSI.
Wherein, ECI is evolved universal terrestrial radio access network cell ID, which can be unique identification one small
Area, ECI are usually to be made of Base Station Identification ENBID and cell ID CellID, and value is usually ENBID × 256+
CellID。
MmeUeS1apId be system distribution, be used for MME one UE of unique identification, i.e. MmeUeS1apId in S1 interface
To identify a business of a UE.Therefore, it is based on MmeUeS1apId, can determine that a UE exists in acquired MRO
The record of the communication information corresponding to all MR reported in communication service.
The MR.LteScRSRP field indicates the signal strength for the current service cell that UE is received.In practical applications,
The MR.LteScRSRP carried in the MR that UE is reported is not the actual signal intensity value of the signal strength, but actual signal
Intensity value adds 140dBm.
The MR.GsmNcellCarrierRSSI field indicates defined neighboring BS relationship and the adjacent area undefined neighboring BS relationship GSM
Carrier received signal intensity instruction, likewise, in practical applications, being carried in the MR that UE is reported
MR.GsmNcellCarrierRSSI is also not actual signal intensity value, adds 110dB for actual signal intensity.
In existing net, when service condition is in communications status, according to the setting period, (now net is traditionally arranged to be UE for meeting
5120ms) MR, the relevant information measured with reporting terminal periodically are sent to base station.Therefore, the period can be set by obtaining
The MR that interior UE is reported obtains the MRO in setting period.It is understood that the duration of the predetermined period can be according to actually answering
With being set, for example, can be set to 1 day, the period is longer, and the MR data got are also more, is based on MR data
ESRVCC handover failure cell localization it is also more accurate.

The information such as TimeStamp, RSRP and RSSI.Fig. 2 and Fig. 3 show in a specific example, the parsing result for showing MRO is shown
It is intended to, as seen from Figure 3, MR report cycle, that is, UE in this example reports the actual interval of a MR for 5120ms, in figure
" id " is ECI, and a line corresponding to " object MmeCode " corresponding one parses obtained communication information record,
The corresponding specific detailed letter for being somebody's turn to do record corresponding to " object MmeCode " of expanding data below " object MmeCode "
Breath.As can be seen from Figure, by parsing the available each MR of MR0 corresponding to MmeUeS1apId, TimeStamp, ECI,
MR.LteScRSRP and MR.GsmNcellCarrierRSSI.Same MmeUeS1apId corresponds to same UE.
By it can be seen from Fig. 2 and Fig. 3 in every communication information record RSRP and RSSI generally can all have it is multiple, can
With according to the selection rule of pre-configuration, choosing one of MR.LteScRSRP and MR.GsmNcellCarrierRSSI conduct should
The MR.LteScRSRP and MR.GsmNcellCarrierRSSI of communication information record.For example, the communication information can be recorded
The MR.LteScRSRP value that any value of multiple MR.LteScRSRP is recorded as this, will be in a communication information record
Value in multiple MR.GsmNcellCarrierRSSI as the MR.GsmNcellCarrierRSSI of this record.
By being described above it is found that since MR.LteScRSRP can be used for characterizing LTE network signal strength,
MR.GsmNcellCarrierRSSI can be used for characterizing GSM network signal strength, therefore, can be longer at one section by obtaining
The MR all to converse that the i.e. interior whole UE of above-mentioned predetermined period occurs in time, the communication information that can be obtained by parsing MR
Record, evaluates the LTE network coverage condition and GSM network coverage condition under LTE cell.

It is understood that the first setting range and the second setting range are accordingly to be adjusted according to actual needs
Whole.In an alternate embodiment of the present invention, the first setting range can be 0 to 97dBm, the second setting range can be 0 to
63dB.At this point, if a communication information record MR.LteScRSRP not 0 between 97dBm, which is recorded
It is determined as exception record, can rejects.If the MR.GsmNcellCarrierRSSI of communication information record is not 0 to 63dB
In range, it is determined that the communication information is recorded as exception record, needs to abandon this record.
In an alternate embodiment of the present invention, the cell of eSRVCC handover failure is gone out according to communication information record location, comprising:
According to ECI, all communication informations record is divided, obtains the corresponding all communication information records of same ECI；
The number for determining the corresponding weak covering sampled point of each same MmeUeS1apId in same ECI, will be in same ECI
The number of the corresponding weak covering sampled point of all same MmeUeS1apId is added, and obtains the corresponding weak total sampling of covering of each ECI

Wherein, the number of weak covering sampled point is to meet the quantity of the record pair of first condition, and record is to being timestamp phase
Adjacent two communication informations record, first condition are as follows:
The time difference of two communication informations record of record pair is equal to the first setting value, and records two communication informations of centering
Record in record there are MR.LteScRSRP less than the second setting value；
The number for determining the corresponding sampled point that declines fastly of same MmeUeS1apId in same ECI, will be each same in same ECI
The number of the corresponding sampled point that declines fastly of one MmeUeS1apId is added, and obtains total number of sampling points K that declines fastly corresponding to each ECI；
Wherein, the number of total sampled point of declining fastly is while meeting the quantity of first condition and second condition recorded pair, the
Two conditions are as follows:
In two communications records of record pair, the RSSI's of the later record of timestamp records earlier with timestamp
The difference of RSSI is less than third setting value；
According to R corresponding to each ECI and K, the cell of eSRVCC handover failure is determined.
It is understood that above-mentioned first setting value, the second setting value and third setting value can be according to actual needs
It is configured.In an alternate embodiment of the present invention, above-mentioned first setting value can be 5020ms with value, and the second setting value can be with
Value is 25dBm (being equivalent to -115dBm), and third setting value can be with value for -12dB.
In the embodiment of the present invention, according to the R and K of each ECI, the cell of eSRVCC handover failure is determined, comprising: if
The R and K of ECI meets third condition, it is determined that cell corresponding to ECI is the cell of eSRVCC handover failure, third condition are as follows:
K is greater than the 4th setting value, and the accounting W that declines fastly, greater than the 5th setting value, W is the ratio of K and R.
Likewise, the 4th setting value and the 5th setting value in above-mentioned third condition can be set according to actual needs
It is fixed.The thresholding value list that the cell that declines fastly is positioned in a specific example of the invention is shown in watch 1, the number that declines fastly in figure corresponds to
Decline sampled point fastly.As can be seen from Table 1, the 4th setting value in this example in third condition can be with value for 50, the 5th setting
Value can be with value for 6%.
Table 1
According to above-mentioned third condition, the cell for the eSRVCC handover failure determined is properly termed as the cell that declines fastly, identifies LTE
The cell of fast-fading can occur for signal, by above it is found that the cell that declines fastly is generally present in the fields such as typical parking lot or tunnel
Jing Zhong.In practical applications, position whether cell corresponding to ECI is that can arrange according to network configuration information when declining cell fastly
Except communication information record corresponding to the high-speed rail cell in acquired communication information record.
Note in the embodiment of the present invention, in two communication information records of record centering there are RSRP less than the second setting value
