Detailed Description
in order to make those skilled in the art better understand the technical solution of the present invention, the base station calibration information extracting method and the base station calibration information extracting system of the present invention are further described in detail below with reference to the accompanying drawings and the detailed description.
The embodiment provides a method for refining base station calibration information, which is used for providing reference for base station information calibration, and the method comprises the steps of matching records in a mobile user internet surfing detailed list collected from a core network of an operator with base station basic information, and comparing lac/cellid numbers in the mobile user internet surfing detailed list with lac/cellid numbers in the base station basic information to obtain two indexes of 'no-flow cell (or no-flow cell proportion)' and 'no-home cell (or no-home cell proportion)', wherein the two indexes reflect the accuracy of base station basic list information; through the assessment of the indexes, the basic information of base stations and base stations in provinces, cities and counties can be updated in time, the indexes are used for assessment of branch companies, and the base stations can be calibrated by the indexes, so that the base station information is more accurate.
In general, a base station includes one or more cells, and the current layout of the base station is, for example, an outdoor base station, which generally has one sector every 120 degrees, so that there are 3 sectors under a base station, and one sector corresponds to one or more cells. A cell is a part of a base station or several cells constitute one base station. The basic information of the cell includes lac/cellid numbers, where one lac/cellid corresponds to one cell, which province, which city, which county, which town street, longitude and latitude, area name and address belong to, the number of the base station where the lac/cellid corresponds to, the network type (2G/3G/4G) of the base station, the type of the base station, the coverage scene, and the like, which refer to fig. 2 specifically. These cell basis data have a great role in assisting operators in network planning, network optimization and even market decision-making.
Each base station has lac + cellid as a unique mark, but for a 'physical' cell, the lac + cellid changes when the network is cut and connected. This part of the information should be adjusted manually whenever there is a change; the method comprises the steps that after the base station is changed and the base station is subjected to capacity expansion operation, the information needs to be manually adjusted.
As shown in fig. 1, the method for refining the calibration information of the base station includes:
step S1: and extracting a lac/cellid number list in the basic information of the base station to form a first base station information list.
In this step, two columns of lac/cellid numbers are extracted from the basic information of the base station shown in fig. 2 to form a first base station information list t 1. The first base station information list t1 at least includes the first appearing traffic time and the last appearing traffic time recorded by lac/cellid number.
The cell information list extracted from fig. 2 is shown in table 1, and it is assumed that table 1 includes all cells.
Table 1 first base station information list t1
step S2: and extracting the lac/cellid number list in the Internet surfing detailed list record of the mobile user to form a second base station information list.
with the development of big data storage and processing technology, operators can collect the full amount of internet surfing recording detailed information of mobile users, and the information is collected from Gn ports of core networks of the operators. For example: table 2 shows details of the mobile subscriber surfing records of 2016, 3, 28, and includes: the mobile phone number, the starting time, the duration, the flow size, the access IP/url, the flow type, the service type and other information, and the user complaints and the like can be solved through the information in the internet record detailed list of the mobile user.
In particular, operators have the ability to collect specific information in the internet record details of mobile subscribers. In general, the core network signaling includes a base station identifier, and when acquiring the details of the mobile user internet record, the base station identifier where the user is on the internet is also acquired and stored. That is, the Gn port signaling also contains lac + cellid information of a base station used by the user for surfing the internet, so that the information acquisition can be slightly upgraded and lac/cellid number information can be acquired at the same time.
Table 2 user internet log detail information
suppose table 2 above is all traffic for a 3 month 28 day user to surf the internet. A second base station information list t2 formed by extracting the lac/cellid number list in the internet detail record of the mobile subscriber from table 2 is shown in table 3:
Table 3 second base station information list t2
In this step, lac/cellid numbers are extracted from the basic information of the base station shown in table 2 to form a second base station information list t2 of table 3, which is the base station number used by the user when actually surfing the internet. The second base station information list t2 at least includes the first appearing traffic time and the last appearing traffic time recorded by lac/cellid number. For example, the first record represents: user XXXX1 started to generate traffic under 28729/11 base stations in 2016, 3, 28, 17: 30.
In practical application, the detailed mobile user internet record (for example, day1) in a period of time may be analyzed, lac/cellid numbers in the mobile user internet record are extracted, a set is established, and finally, the second base station information list t2 is formed. The second base station information list t2 generally includes many identical lac/cellid number records, and in order to ensure data reduction, it is preferable to delete many duplicate lac/cellid numbers, and only keep any one of the identical lac/cellid number records, and as long as there is one record, it indicates that the base station exists.
it should be understood here that steps S1 and S2 are two independent information acquisition phases, and both can continuously acquire and store information all day long, with virtually no back-and-forth order.
step S3: and comparing the first base station information list t1 with the second base station information list t2 to screen out a 'cell without flow' and a 'cell without attribution'.
in this step, the base station corresponding to the lac/cellid number record only in the second base station information list t2 but not in the first base station information list t1 is set as a "no-home cell", and the base station corresponding to the lac/cellid number record only in the first base station information list t1 but not in the second base station information list t2 is set as a "no-traffic cell", wherein the base station information of the "no-home cell" and the "no-traffic cell" includes at least the first occurrence traffic time and the last occurrence traffic time of the lac/cellid number record.
Assuming that the set of the first BS information list t1 is A and the set of the second BS information list t2 is B, there are, as shown in FIG. 3:
The intersection A and B of A and B represents lac/cellid number records shared by the first base station information list t1 and the second base station information list t2, namely those base stations which exist in the base station basic information list and can be found in the mobile user internet access record detailed list;
The complementary set of B, C £ B, represents the lac/cellid number records only in the first base station information list t1 but not in the second base station information list t2, i.e., the base stations that appear in the base station basic information table but have no traffic found in the mobile internet record details, and these corresponding base stations are set as "no-traffic cells";
the complement of a, cove, indicates lac/cellid number records only in the second base station information list t2 but not in the first base station information list t1, that is, base stations which do not appear in the base station basic information table but have traffic in the mobile user internet access record details, and these corresponding base stations are set as "non-home cells".
In fact, the "no-flow cell" and the "no-home cell" are both caused by the fact that the basic information of the base station shown in fig. 2 is not updated in time due to the data that is manually maintained and reported step by step, and the "no-flow cell" and the "no-home cell" are generated by comparing the basic information with the base station that appears in the internet detailed list data of the mobile user.
according to the first base station information list t1 in table 1 and the second base station information list t2 in table 3, comparing t1 with t2, if the base station with lac/cellid information in t2 but without lac/cellid information in t1 is a cell without home, and if the base station with lac/cellid information in t1 but without lac/cellid information in t2 is a cell without traffic. Therefore, according to tables 1 and 3, comparing the first base station information list t1 and the second base station information list t2 results in:
The "no-flow cell" is: 28739/11, 28739/21, 28739/31, 15432/31, 15432/41, 15440/11, 15441/11, indicating that these cells are not present in the flow record for day 28/3 month, i.e. no flow for day 28/3 month.
The "cell without home" is: 77777/11 and 88888/11 show that the traffic generated by these cells is found in the user internet traffic record, but no information is registered in the cell information table.
At this point, the table t1 for the analysis of the day after becomes (this step is also equivalent to calibrating the no-traffic cell, i.e. for the cell where traffic occurs, modifying the time of the last occurrence of traffic):
table 42016 year, 3 month, 28 day traffic information
If there is a record in the previous non-home cell table:
as can be seen from the table above, this cell without home is added when analyzing the data of 2016, 1, 15 and the first time traffic appears. For example, the 88888 cell in the table below was newly added when data was analyzed for days 3, 28, 2016. That is, when one of the two non-home cells is found in 2016, 3, 28, the last flow time of the record of the existing non-home cell is updated, and a new record of the non-home cell is added, at this time, the base station management platform automatically modifies the non-home cell table according to the base station information to become:
In practical situations, there are many cases that result in "no-traffic cells", "no-home cells", for example:
If there is a new base station, but no information is entered into the first base station information list t1 shown in table 1, a "cell without home" appears;
if the lac or cellid of a group of base stations changes due to network adjustment, for example, lac1 and cellid1 are changed into lac2 and cellid2, but are not updated in the first base station information list t1 shown in table 1, lac1 and cellid1 will become "no-flow cells", and lac2 and cellid2 will become "no-home cells";
if the base station has been deactivated but not deleted in the first base station information list t1 shown in table 1, it becomes "garbage data", and a "no-traffic cell" occurs.
Step S4: the base stations in the "no home cell" and/or the base stations in the "no traffic cell" are compared with a management list including all base station information for calibrating the base station information.
and collecting a base station range table of lac numbers of provinces, cities and counties, comparing a management list comprising all base station information with base stations in the cell without attribution and base stations in the cell without flow, and calibrating the base station information.
Base station calibration for "no home cell" includes:
the base station information is classified, and the abnormal base station is divided into a 'home abnormal cell' (namely a base station list with abnormal home in a management list of all base station information) and a 'flow abnormal cell' (namely a base station list with abnormal flow in the management list of all base station information, wherein the abnormal flow can be reflected by the last flow time).
for example, a home abnormal base station list X is set, the cells can be correctly identified with their home information (for example, belonging to suzhou or shanghai), but the home information is not correctly entered (for example, the basic information is not entered in the base station management data of suzhou or shanghai), and there are several columns of first-time traffic occurrence time, last-time traffic occurrence time, home province, home city, home county, etc. of the corresponding base station recorded with lac/cellid number in the list X. In this step, "cell without home" obtained by extracting and analyzing the time of the mobile user surfing detailed record display in step S3 as day1 comparison is compared with the base station information in table X one by one:
1) If there is no base station in "no home cell" in table X, then the base station is added to table X, and the first occurring traffic time and the last occurring traffic time are set to day 1. That is, when the non-home cell is found for the first time, the first occurring traffic time and the last occurring traffic time are both the time of first finding traffic (i.e. day1) recorded by extracting the analyzed details of the mobile user's presence. And recording the first occurrence time and the last occurrence time of the traffic for the cell without the home, so as to provide convenience and information for subsequent manual calibration or automatic calibration.
2) If there is a base station in "no home cell" in table X, the latest traffic time of the base station is modified to day 1. That is, when the base station list with the abnormal home location has the cell without the home location, the first time flow occurrence time of the cell does not need to be changed (it is not changed any more later), but the last time flow occurrence time of the cell needs to be changed to the time for displaying the last flow occurrence of the mobile user online detailed list record extracted and analyzed.
For example: analyzing records of 4 months and 11 days yesterday, wherein the last flow time of the cell without attribution in the base station list with the abnormal attribution is 4 months and 11 days; today, the mobile user surfing detailed record of 4 months and 12 days is analyzed, the cell without the home is found, and the last flow time of the cell needs to be modified to 4 months and 12 days.
Another example is: the emergency communication vehicle is moved at a place of 3 months and 22 days due to the fact that a singing is held, the non-attributive cell appears when the record of 3 months and 22 days is analyzed, but the emergency communication vehicle is withdrawn at 3 months and 23 days, and if the information of the base station is not available, the non-attributive cell is mixed with other non-attributive cells. For example, the first occurrence of the traffic time may determine that there is activity that day and the emergency communication vehicle is indeed moved, and by 12 days in 4 months, the last traffic time of the cell without home is still maintained at 22 days in 3 months, which indicates that the cell without home is not already present and the processing and non-processing relationship is not large.
meanwhile, a base station range table P of lac numbers of provinces, cities and districts is collected, and the information of the province, city and district of the base station of the 'attribution abnormal cell' can be determined by inquiring the table P. Therefore, the 'attribution abnormal cell' can be checked downwards step by step, wherein the time of the first occurrence of flow and the time of the last occurrence of flow can assist in positioning the non-attribution base station.
the calibration of the base station to the 'abnormal traffic cell' comprises the following steps: comparing the base station information of the "no-traffic cell" in step S3 with the list of traffic abnormal base stations in the management list of all base station information one by one: and updating the latest traffic time of other base stations except the 'no-traffic cell'.
with the "last traffic time" column in the first base station information list t1, the base station of the "no-traffic cell" in step S3 does not update its last traffic time, and the other base stations update the last traffic time to day 1. Therefore, the proportion of the no-flow base station with the time of 1 day, 2 days and more than 3 days can be examined, and the examination is carried out step by step.
by adopting the method for refining the calibration information of the base station, if the calibration operation is performed once a day, only the information of a certain day needs to be recorded, for example, the data of 3 months and 28 days before the operation of 3 months and 29 days is analyzed.
according to the first base station information list t1, 28739/11 has no traffic in two days of 3 months, 27 days and 3 months, 28 days; 15441/11 no flow from 20 days 3 month to 28 days 3 month; from table 3, it can be seen that 77777/11 no-home cell is generated for 8 days (analysis day from 3 months 21 days to 3 months 29 days), how can you get back? If 15441/11 and 77777/11 are both cells in Suzhou, through the content screened by the table, at this time, the examiner in information management of the Suzhou base station can find a cell with no traffic for many days in time and a cell without attribution for the same number of days, and theoretically, the examiner can solve the problem of inaccurate cell information table by modifying 15441/11 to 77777/11. Of course, how to calibrate the cell management information by using the cell information obtained in the present application is a specific assessment method for management means of each company, and is not limited herein.
normally, the "traffic abnormal cell" is not calibrated, because there is only 3 months and 28 days of traffic possible, and the basic information of the base station is correct. For example, when data of 3 month and 28 days are analyzed on 29 days of 3 months, the last flow of most base stations is 27 days of 3 months, and 28729/11 the base station generates no flow on 3 months and 27 days of 3 months, so the last flow time is still 26 days of 3 months, but after the data of 28 days of 3 months is analyzed, 28729/11 the base station has flow, and then 28729/11 the last flow time is directly changed to 28 days of 3 months.
