Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flow chart of a method for backfilling user location information according to a preferred embodiment of the present invention is schematically shown, which can be executed on a terminal device, and includes the following steps:
and S10, acquiring the signaling data of the user to be identified in the time period every preset time period.
In this embodiment, the terminal device may be a mobile terminal such as a mobile phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), or a digital broadcast receiver, or may be a fixed terminal such as a digital TV, a desktop computer, or a server. In this embodiment, the whole signaling data on an LTE (Long Term Evolution ) network is collected every preset time period, and the signaling data of a single user in the time period is obtained. For example, every 15 minutes (taking 15 minutes as time granularity), all signaling data (e.g., S1-U signaling data) of a single subscriber (i.e., the subscriber to be identified) can be obtained by judging through the subscriber identity field IMSI (International mobile subscriber identity).
S20, identifying the type of the user according to the signaling data, and detecting whether the type of the user is a static user.
In this embodiment, after the signaling data of the user is collected, the signaling data is analyzed, for example, base station information or cell information occupied by the user in the time period is obtained and analyzed, and it is determined whether the user moves obviously in the time period, if the user moves not obviously in the position, the state of the user is considered as a static behavior in the time period, and is determined as a static user, and if the user moves obviously in the position (for example, the user moves obviously indoors and outdoors), the state of the user is considered as a mobile behavior, and is determined as a non-static user or a mobile user.
And S30, when the type of the user is detected to be a static user, acquiring the position information of the user and backfilling the position information into the wireless information of the user.
In this embodiment, when the user is determined to be a static user, the position of the user in the time period is considered to be unchanged, so that the position information corresponding to all the wireless information generated by the user in the time period is also the same, and then the position information (i.e., latitude and longitude information) reported by the user is obtained and backfilled into the wireless information, where the wireless information is MR (Measurement Report) data, service signaling, and the like.
By the method, different users can be analyzed and judged so as to backfill corresponding position information, whether the users are static users or not is judged, and all wireless information generated by the static users in the time period is backfilled according to the position information corresponding to the static users, so that the quantity of the wireless information backfilled by the longitude and latitude of the users is ensured, the backfilling accuracy of the longitude and latitude of the users is also ensured, and the problem that the backfilling quantity and the backfilling accuracy of the prior art are difficult to coexist is solved.
In another preferred embodiment of the present invention, step S20 specifically includes:
determining the cell type occupied by the user in the time period according to the signaling data;
extracting detailed call ticket data of the user in the time period from the signaling data;
and detecting whether the type of the user is a static user or not according to the cell type and the detailed call ticket data.
In this embodiment, the signaling data includes user identity information, switching location information (e.g., occupied cell information, etc.), user service information, and the like of the user in the time period, so that the cell type occupied by the user can be determined, and the cell type occupied by the user in the time period is determined to be a room-divided cell or a non-room-divided cell, it should be noted that the cell types are divided into two types: in the construction of a base station for mobile communication, indoor construction is generally provided with an indoor coverage base station, and therefore, a cell of the indoor coverage base station is referred to as an indoor sub-cell, and conversely, the cell is referred to as a non-indoor sub-cell.
Then, extract the detailed Call ticket data of the user in the event cycle, i.e. XDR data (X Detail Record), i.e. detailed records of the Call process and the Transaction processing in the mobile communication system, including CDR data (Call Detail Record) and TDR data (Transaction Detail Record), from the signaling data, for example, with a granularity of 15 minutes, obtain all XDR data of the user, i.e.:
unique IMSI15 minutes：SET(XDR1,XDR2,XDR3,XDR4,.......XDRn)
Wherein n is the number of XDR. And judging the XDR data extracted by different algorithms according to the detected cell type, and judging whether the user is a static user, wherein the XDR data comprises user identity information, switching position information (such as cell information, base station information and the like) and other data corresponding to the time period.
In an implementation manner of this embodiment, specifically:
if the cell type occupied by the user is a room division cell, acquiring the base station type of each base station occupied by the user according to a preset base station work participation table and the detailed call ticket data;
calculating the detailed call ticket data ratio of each base station according to the detailed call ticket data, and recording the number of cells which change in the time period;
and detecting whether the type of the user is a static user or not according to the base station type of each base station, the detailed call ticket data ratio and the number of the cells.
Here, XDR data generated for a user occupancy cell is judged by an algorithm. When the cell type occupied by the user is an indoor sub-cell, all base stations occupied by the user in the time period can be obtained from the detailed call ticket data, and meanwhile, the detailed call ticket data is associated with a preset base station work reference table, so that the base station type of each base station occupied by the user can be obtained, wherein the base station work reference table comprises preset base station information, namely a base station identifier (enb id), a base station position (base station specific longitude and latitude), a base station type and the like of each preset base station, so that the detailed call ticket data is associated with the base station work reference table, so that the base station type and the XDR data of each base station occupied by the user can be obtained, for example:
enbid1type is indoor(XDR1,XDR2,XDR3,XDR4,.......XDRn)
enbid2type is outdoor(XDR1,XDR2,XDR3,XDR4,.......XDRn)
And further calculating the detailed call ticket data ratio of each base station occupied by the user. Here, if the user occupies the indoor base station, it indicates that the user is located in a building, and if the user moves the location, the measured neighboring cell also changes greatly, so when the base station occupied by the user is obtained, the change of the main neighboring cell occupied by the user is analyzed, and the number of changed cells (i.e., the number of pci) is recorded, for example:
Σde-weighting(enbid1,enbid2,....enbidn,pci1,pci2,pci3,.....,pcin)
And finally, judging whether the base station occupied by the user, the data occupation ratio and the number of the changed cells meet preset conditions to detect whether the type of the user is a static user.
Specifically, if it is detected that the detailed call ticket data proportion of the only first base station in the base stations is greater than or equal to a preset proportion threshold and the number of the cells is less than or equal to a preset number threshold, it is determined that the type of the user is detected to be a static user; and the base station type of the first base station is an indoor base station.
It can be understood that the ratio threshold, the number threshold, and the like may be set according to an actual situation, for example, if it is detected that the ratio of the detailed call ticket data of only one base station (i.e., the first base station) is greater than or equal to 80% (ratio threshold) and the type of the base station is an indoor base station among all the occupied base stations, and the number of the cells that change at the same time is less than or equal to 6 (number threshold), it is determined that the user is in a static behavior within the time period (15 minutes), that is, a "static user"; otherwise, the behavior type of the user in the time period is a mobile behavior, that is, the mobile user may discard the related data or the location information. For example, 15-minute data of the user is obtained, when there is only one base station M with the type of the indoor base station that satisfies the following two determination conditions, it is determined that the user is a static user in the 15 minutes, and otherwise, the user is a mobile user, where the two determination conditions are as follows:
Σde-weighting(enbid1,enbid2,....enbidn,pci1,pci2,pci3,.....,pcin)<＝6
Further, the step S30 specifically includes:
when the type of the user is detected to be a static user, acquiring first position information of a base station occupied by the user from preset base station engineering data and backfilling the first position information into wireless information of the user;
and acquiring second position information reported by the user in the time period, and supplementing and backfilling the second position information into wireless information of the user.
It should be noted that, when it is detected that the user occupies the indoor sub-cell and the user is a static user, all wireless information generated by the user in the time period is preferably backfilled by using longitude and latitude (first location information) of the indoor sub-cell recorded on preset base station engineering information, and is backfilled by using longitude and latitude information (second location information) reported by the user in the time period, where the preset base station engineering information is engineering information constructed by an indoor coverage base station of a mobile operator, and the longitude and latitude information of the indoor sub-cell is recorded on the engineering information.
In another implementation manner of the embodiment of the present invention, specifically:
if the cell type occupied by the user is a non-indoor cell, acquiring the base station type of each base station occupied by the user and the position data of each base station according to a preset base station work attendance table and the detailed call ticket data;
when the base station types of all the base stations are detected to be outdoor base stations, calculating the base station distance between every two base stations according to the position data of each base station;
recording the number of cells which change in the time period and the signal change of a main cell according to the detailed call ticket data;
and if the detected distance of each base station is smaller than a preset distance threshold, the number of the cells is smaller than or equal to a preset number threshold, and the signal change is smaller than a preset signal threshold, judging that the type of the detected user is a static user.
Here, XDR data generated for a user occupying a non-indoor cell is judged by an algorithm. When the cell type occupied by the user is a non-indoor sub-cell, all base stations occupied by the user in the time period can be obtained from the detailed call ticket data, and meanwhile, the detailed call ticket data is associated with a preset base station work-reference table, so that the base station type of each base station occupied by the user and the position data (longitude and latitude information) of each base station can be obtained, wherein the base station work-reference table comprises preset base station information, namely a base station identifier (enbid) of each preset base station, a base station position (specific longitude and latitude of the base station), a base station type and the like, so that the detailed call ticket data is associated with the base station work-reference table to obtain the longitude and latitude of each base station occupied by the user, and when all the base stations occupied by the user are outdoor base stations, the base station distance between every two base stations is calculated according to the longitude and latitude of each base station, for example:
∪distance between two adjacent plates(enbid1,enbid2,enbid3,.......，enbidn)
Further, when the user moves the location, the measured neighboring cell also changes greatly, so when the base station occupied by the user is acquired, the change of the primary neighboring cell occupied by the user is analyzed, and the number of changed cells (that is, the number of pci) is recorded, for example:
Σde-weighting(enbid1,enbid2,....enbidn,pci1,pci2,pci3,.....,pcin)
Meanwhile, Signal changes of the RSRP (Reference Signal Receiving Power) of the primary cell need to be recorded, for example:
±rsrp(enbid1_rsrp,enbid2_rsrp,enbid3_rsrp,.....enbid4_rsrp)
and finally, judging whether the type of the user is a static user or not by judging whether the type of the base station occupied by the user, the distance of the base station, the number of changed cells and the signal change meet preset conditions or not.
As an example, if it is detected that all base stations occupied by the user are outdoor base stations, the base station distances of all base stations are less than 600 meters (distance threshold), the number of cells with changed neighboring cells is less than or equal to 6 (number threshold), and the RSRP signal change of all main cells is less than 6dBm (signal threshold), it is determined that the user is in a static behavior within the time period (15 minutes), that is, a "static user"; otherwise, the behavior type of the user in the time period is a mobile behavior, that is, the mobile user may discard the related data or the location information. For example, 15-minute data of the user is obtained, when all occupied base stations are indoor base stations and the following three determination conditions are met, it is determined that the user is a static user in the 15 minutes, and otherwise, the user is a mobile user, where the three determination conditions are as follows:
∪distance between two adjacent plates(enbid1,enbid2,enbid3,.......，enbidn)<600 m ═
ΣDe-weighting(enbid1,enbid2,....enbidn,pci1,pci2,pci3,.....,pcin)<＝6
±rsrp(enbid1_rsrp,enbid2_rsrp,enbid3_rsrp,.....enbid4_rsrp)<＝6dBm
Further, the step S30 specifically includes:
and when the type of the user is detected to be a static user, acquiring the position information reported by the user in the time period, and supplementing and backfilling the position information into the wireless information of the user.
Here, it is determined that all wireless information of the non-indoor partition static user is backfilled by mainly using the longitude and latitude reported by the user in the time period, that is, when the user is determined to be a static user, the position of the user in the time period is considered to be unchanged, and therefore, the position information corresponding to all wireless information generated by the user in the time period is also the same, and the position information (i.e., the longitude and latitude information) reported by the user is obtained and backfilled into the wireless information.
By the mode, according to the type of the cell occupied by the user in the time period, the position movement of the user is judged by using different algorithms, and the static user occupying the indoor sub-cell and the static user occupying the non-indoor sub-cell can be accurately identified; and for all wireless information of the users judged to be static, backfilling the longitude and latitude of the base station for the users occupying the indoor sub-cell and backfilling the accurate longitude and latitude reported at the position for the users occupying the non-indoor sub-cell, so that the quantity of the wireless information backfilled by the longitude and latitude of the users is ensured, and the backfilling accuracy of the longitude and latitude of the users is also ensured.
