Detailed ways

Features and exemplary embodiments of various aspects of the invention are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the invention. The present invention is in no way limited to any specific configurations and algorithms set forth below, but covers any modification, substitution and improvement of elements, components and algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the present invention.

FIG. 1 shows a schematic flowchart of a cell location method for a communication network handover failure in an embodiment of the present invention. As shown in Figure 1, the cell positioning method may mainly include the following steps:

Step S11: Obtain measurement report sample data MRO reported by the UE in a preset period.

Step S12: Analyze the MRO to obtain a communication information record corresponding to each MR in the MRO.

In the embodiment of the present invention, a communication information record corresponding to each MR in the acquired MRO can be obtained by parsing the MRO. In each communication information record, the Evolved Universal Terrestrial Radio Access Network cell identifier ECI and the network node of the user terminal are obtained. Unique identifier MmeUeS1apId, timestamp TimeStamp, LTE serving cell reference signal received power MR.LteScRSRP and GSM neighbor cell carrier received signal strength indication MR.GsmNcellCarrierRSSI.

Among them, ECI is an Evolved Universal Terrestrial Radio Access Network cell identifier, which can uniquely identify a cell. ECI is usually composed of base station identifier ENBID and cell identifier CellID, and the value is usually ENBID×256+CellID.

MmeUeS1apId is allocated by the system and is used by the MME to uniquely identify a UE in the S1 interface, that is, MmeUeS1apId is used to identify a service of a UE. Therefore, based on MmeUeS1apId, it is possible to determine the communication information records corresponding to all MRs reported by a UE in one communication service in the acquired MRO.

MR.LteScRSRP This field indicates the signal strength of the current serving cell received by the UE. In practical applications, the MR.LteScRSRP carried in the MR reported by the UE is not the actual signal strength value of the signal strength, but the actual signal strength value plus 140dBm.

MR.GsmNcellCarrierRSSI This field indicates the received signal strength indication of the GSM adjacent cell carrier with defined neighbor relationship and undefined neighbor relationship. Similarly, in practical applications, the MR.GsmNcellCarrierRSSI carried in the MR reported by the UE is not the actual signal strength. value, add 110dB to the actual signal strength.

In the existing network, when the UE is in the service state, that is, in the communication state, it will periodically send MR to the base station according to the set period (generally set to 5120ms in the existing network) to report the relevant information measured by the terminal. Therefore, the MRO of the set period can be obtained by acquiring the MR reported by the UE within the set period. It can be understood that the duration of the preset period can be set according to actual application needs. For example, it can be set to 1 day. The longer the period is, the more MR data is acquired, and the eSRVCC switching based on MR data fails. Cell positioning is also more accurate.

The sample data MRO of the measurement report is studied. By analyzing the MRO, information such as ECI, MmeUeS1apId, TimeStamp, RSRP and RSSI can be obtained at the same time. Figure 2 and Figure 3 show a specific example, showing a schematic diagram of the analysis result of the MRO. It can be seen from Figure 3 that the MR reporting period in this example, that is, the actual interval for the UE to report an MR once is 5120 ms. id" is ECI, a line corresponding to "object MmeCode" corresponds to a communication information record obtained by parsing, and the expanded data under "object MmeCode" corresponds to the specific details of the record corresponding to "object MmeCode". As can be seen from the figure, MmeUeS1apId, TimeStamp, ECI, MR.LteScRSRP and MR.GsmNcellCarrierRSSI corresponding to each MR can be obtained by analyzing MR0. The same MmeUeS1apId corresponds to the same UE.

As can be seen from Figure 2 and Figure 3, there are generally multiple RSRPs and RSSIs in each communication information record, and one of the MR.LteScRSRP and MR.GsmNcellCarrierRSSI can be selected as the communication information according to the pre-configured selection rules. Recorded MR.LteScRSRP and MR.GsmNcellCarrierRSSI. For example, any value of multiple MR.LteScRSRPs in the communication information record can be used as the MR.LteScRSRP value of the record, and the value of MR.GsmNcellCarrierRSSI of the record in the multiple MR.GsmNcellCarrierRSSIs in a communication information record can be used as the record. value.

As can be seen from the foregoing description, since MR.LteScRSRP can be used to characterize the signal strength of the LTE network, and MR.GsmNcellCarrierRSSI can be used to characterize the signal strength of the GSM network, it can be obtained by obtaining all UE occurrences within a relatively long period of time, that is, within the above preset period. The MR of all calls can be analyzed by analyzing the communication information records obtained by the MR to evaluate the LTE network coverage and GSM network coverage in the LTE cell.

Step S13: Locate the cell where the eSRVCC handover fails according to all the communication information records.

In the embodiment of the present invention, the cell where the eSRVCC handover fails is a fast-fading cell or a double-weak cell, where the fast-fading cell refers to a cell where the LTE signal will rapidly fade, which generally occurs in application scenarios such as parking lots and tunnels. . Double weak cells refer to cells with weak LTE network signals and GSM network signal cells.

In order to improve the accuracy of the location of the cell where the eSRVCC handover fails, in this embodiment of the present invention, before locating the cell where the eSRVCC handover fails according to all communication information records, the method further includes: deleting the acquired abnormal communication information record, the abnormal communication information The records include records whose MR.LteScRSRP exceeds the first set range and MR.GsmNcellCarrierRSSI which exceeds the second set range.

It can be understood that, both the first setting range and the second setting range can be adjusted according to actual needs. In an optional embodiment of the present invention, the first setting range may be 0 to 97 dBm, and the second setting range may be 0 to 63 dB. At this time, if the MR.LteScRSRP of a communication information record is not between 0 and 97dBm, the communication information record is determined as an abnormal record and can be eliminated. If the MR.GsmNcellCarrierRSSI of a communication information record is not within the range of 0 to 63 dB, it is determined that the communication information record is an abnormal record, and the record needs to be discarded.

In an optional embodiment of the present invention, locating the cell where the eSRVCC handover fails according to the communication information record includes:

According to ECI, divide all communication information records to obtain all communication information records corresponding to the same ECI;

Determine the number of weak coverage sampling points corresponding to each same MmeUeS1apId in the same ECI, and add the number of weak coverage sampling points corresponding to all the same MmeUeS1apId in the same ECI to obtain the total number of weak coverage sampling points corresponding to each ECI R;

The number of weak coverage sampling points is the number of record pairs that satisfy the first condition, and the record pairs are two communication information records with adjacent time stamps. The first condition is:

The time difference between the two communication information records of the record pair is equal to the first set value, and there is a record in which MR.LteScRSRP is less than the second set value in the two communication information records of the record pair;

Determine the number of fast fading sampling points corresponding to the same MmeUeS1apId in the same ECI, and add the number of fast fading sampling points corresponding to each same MmeUeS1apId in the same ECI to obtain the total number of fast fading sampling points corresponding to each ECI K;

Among them, the number of fast decay total sampling points is the number of record pairs that satisfy the first condition and the second condition at the same time, and the second condition is:

In the two communication records of the record pair, the difference between the RSSI of the record with a later timestamp and the RSSI of the record with an earlier timestamp is less than the third set value;

According to R and K corresponding to each ECI, determine the cell where the eSRVCC handover fails.

It can be understood that, the above-mentioned first set value, second set value and third set value can all be set according to actual needs. In an optional embodiment of the present invention, the first setting value may be 5020ms, the second setting value may be 25dBm (equivalent to -115dBm), and the third setting value may be -12dB .

In the embodiment of the present invention, determining the cell where the eSRVCC handover fails according to the R and K of each ECI, including: if the R and K of the ECI satisfy the third condition, determining that the cell corresponding to the ECI is the cell where the eSRVCC handover fails, The third condition is:

K is greater than the fourth set value, and the fast decay ratio W is greater than the fifth set value, where W is the ratio of K to R.

Similarly, both the fourth set value and the fifth set value in the above-mentioned third condition can be set according to actual needs. Table 1 shows a list of threshold values for locating fast-fading cells in a specific example of the present invention, and the fast-fading times in the figure correspond to fast-fading sampling points. As can be seen from Table 1, in this example, the fourth setting value in the third condition may take a value of 50, and the fifth setting value may take a value of 6%.

Table 1

According to the above third condition, the determined eSRVCC handover failed cell can be called a fast-fading cell, which identifies a cell where the LTE signal will rapidly fade. As can be seen from the foregoing, fast-fading cells generally appear in typical parking lots or tunnels and other scenarios. In practical applications, when locating whether the cell corresponding to the ECI is a fast-fading cell, the communication information record corresponding to the high-speed rail cell in the acquired communication information record can be excluded according to the network configuration information.

In the embodiment of the present invention, there are records whose RSRP is less than the second set value in the two communication information records in the record pair, preferably, the RSRP of the communication information record with an earlier timestamp in the two communication information records in the record pair is smaller than the second set value. Value.

In the embodiment of the present invention, based on the MR data, the evaluation of the fast fading situation at the cell level of the whole network is realized. Since the cell with eSRVCC handover failure is finally located, after analyzing the MRO to obtain a communication information record corresponding to each MR in each MRO, all the communication information records can be recorded according to the ECI first. Divide to obtain all the communication information records corresponding to the same ECI, and store all the communication information records of the same ECI in a data table, and determine the cell corresponding to the ECI based on all the communication information records corresponding to each ECI. Whether it is the cell where the eSRVCC handover fails.

As shown in Table 2, it corresponds to the communication information record table of the cell with ECI of 4355451. The RSSI of the communication information record in Table 2 is not shown), and each row corresponds to one communication information record. For example, the communication information record corresponding to the second line, the record is that the EC ID is 4355451, the MmeUeS1apId is 19776, the TimeStamp is 15:16:59.520 on May 18, 2016, and the MR.LteScRSRP is 26dBm (relative value, actual value 26dBm-140dBm) a communication information record.

Table 2

In practical applications, for the efficiency of data processing, for all communication information records in the same table (corresponding to the same ECI), these records can be sorted according to MmeUeS1apId. For the sorted records corresponding to the same MmeUeS1apId in the same ECI, Sorting can be performed in ascending order based on time sequence, so as to obtain the result that the communication information records of the same MmeUeS1apId of the same cell are arranged in chronological order. The communication information record table shown in Table 2 is the sorted result. For the UE corresponding to the MmeUeS1apId of 19776, there are 5 communication information records in total, and the time sequence is shown in column C.

For the communication information recording table shown in Table 2, the first setting value is 5120ms, the second setting value is 25dBm, and the third setting value is -12dB. That is, in the communication records corresponding to the same MmeUeS1apId, the time stamps are adjacent to each other (that is, after the communication information records are sorted according to the time stamps, the time stamps corresponding to the adjacent two records are adjacent time stamps), the time stamps are adjacent to each other. The MR.LteScRSRP of the earlier record is denoted as RS _N , the timestamp of the record with an earlier timestamp is T _N , the MR.LteScRSRP of the record with a later timestamp is denoted as RS _N-1 , and the timestamp of the later record is T N _N-1 . The steps to determine R and K of an ECI can be as follows:

First, the number of weak coverage sampling points and the number of fast fading sampling points corresponding to each MR.LteScRSRP are determined respectively. The method of determining the number of weak coverage sampling points and the number of fast fading sampling points corresponding to an MR.LteScRSRP may include:

The values of the two adjacent rows in column B (field: MmeUeS1apId) are equal, that is, the communication information record of the same UE. At this time, if RS _N <25dBm and T _N -T _N-1 ≤5120ms, the weak coverage of the MmeUeS1apId The number of sampling points is incremented by 1. When RS _N < 25dBm and T _N -T _N-1 ≤5120ms, if R _N -R _N-1 <-12dB, it indicates the sampling point signal of the UE at this time point The strength is 12dB weaker than the signal strength of the last sampling point with an interval of 5120ms (the empirical value of fast fading of the signal), which is equivalent to a fast fading event at this time, and the number of fast fading sampling points corresponding to the MR.LteScRSRP is increased by 1.

After calculating the number of weak coverage sampling points and the number of fast fading sampling points corresponding to each MR.LteScRSRP of the same ECI, the number of weak coverage sampling points corresponding to all MR.LteScRSRP can be added to obtain the For the R corresponding to the ECI, add the number of fast-fading sampling points corresponding to all MR.LteScRSRP to obtain the K corresponding to the ECI, calculate the K and R corresponding to the ECI, and based on K and R, you can calculate the W=K/R corresponding to the ECI. At this time, it can be determined whether the cell corresponding to the ECI is a fast-fading cell according to the calculated K, R, and W and the above-mentioned third condition. In the above manner, it can be determined which cells corresponding to the ECIs among the ECIs involved in the acquired MRO of the preset period are fast-fading cells.

Specifically, for the communication information records in the ECI communication information record table of 4355451 shown in Table 2, corresponding to the same ECI, the initial values of R and K are both 0. For the communication information records shown in Table 1, A 4355451 in row 3 of column = 4355451 in row 2, the difference between row 3 of column C and row 2 of column C is 5120ms, 19776 of row 3 of column B = 19776 of row 2 and the value of row 3 of column D<25dBm , then the R value of the ECI is +1, at this time R=1, and the difference between the value of 12dBm in the third row of column D and the value of 26dBm in the second row of column D is -14dBm, which is less than -12dBm, so the K value +1 , and K=1 at this time.

In the embodiment of the present invention, the cell where the eSRVCC handover fails is located according to the communication information record, including:

Count the number of records Z of all communication information records corresponding to each ECI;

The number of double weak sampling points S corresponding to each ECI is counted, and the double weak sampling points are the number of communication information records that meet the fourth condition. The fourth condition is:

RSRP is less than the sixth set value, and RSSI is less than the seventh set value;

According to Z and S corresponding to each ECI, determine the cell where the eSRVCC handover fails.

In the embodiment of the present invention, according to Z and S corresponding to each ECI, determine the cell where the eSRVCC handover fails, including:

If the S and Q corresponding to the ECI satisfy the fifth condition, the cell corresponding to the ECI is determined to be the cell where the eSRVCC handover fails, and the fifth condition is:

S is greater than the eighth set value, and the double weak ratio Q is greater than the ninth set value, where Q is the ratio of S to Z.

According to the above fifth condition, the determined cell where the eSRVCC handover fails may be referred to as a double-weak cell, indicating a cell with weak LTE signals and GSM signals.

It can be understood that the above-mentioned sixth setting value, seventh setting value, eighth setting value and ninth setting value can also be adjusted according to the actual situation of the existing network. By adjusting different setting values, Adjust accordingly to determine the severity of eSRVCC failure scenarios. In a specific example of the present invention, the sixth setting value may be 25dBm, and the seventh setting value may be 15dBm.

Table 1 shows a list of threshold values for locating double-weak cells in a specific example of the present invention, and the number of double-weak cells in the figure corresponds to the number of double-weak sampling points. It can be seen from Table 3 that the eighth setting value in the fifth condition may be 500, and the ninth setting value may be 10%.

Fifth condition number of times Proportional limit Double Weak Judgment Double Weak Times>500 Double weak proportion>10%

Through the method of the embodiment of the present invention, the cell with eSRVCC handover failure (a cell with a high probability of eSRVCC handover failure) can be quickly and accurately determined, and it can be further identified whether the cell with eSRVCC handover failure is a dual-weak cell or a fast-fading cell community. The solution of the embodiment of the present invention, based on MRO big data information, can comprehensively evaluate the double weak and fast fading degree of each cell in the whole network, overcome the one-sidedness and limitation of traditional analysis through drive test data, and provide targeted network optimization. It provides a strong basis, and the positioning results are clear to the optimizer, which better meets the needs of practical applications.

In practical applications, according to actual needs, the targeted handover threshold can be optimized. For example, in the LTE fast fading scene cell, the start-up test and handover threshold can be increased), so as to generate eSRVCC to GSM cell as soon as possible, and avoid entering the fast fading scene and cause eSRVCC Switchover failed. It can be understood that the specific values of the above-mentioned setting values in this embodiment of the present invention may be set and adjusted according to empirical values, so as to limit the strictness of determining the location of the eSRVCC failure scenario.
