Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Currently, an LTE network data acquisition system locates a user by using a UE _ MR user behavior record. Specifically, firstly, the UE reports a Measurement Report (MR) message to the base station through the Uu interface, and the base station outputs the MR message to the data acquisition system according to a specified data format after receiving the MR message; the data acquisition system processes the data to generate a UE-MR user behavior record, wherein the UE-MR user behavior record comprises a measurement result of a neighboring cell in an MR message, and a time Advance (TA, Timing Advance) and an Arrival Angle (AoA, Angle-of-Arrival) obtained by a base station through measurement; the data acquisition system further uses the information to perform positioning calculation to obtain the longitude and latitude corresponding to the UE _ MR user behavior record, and backfills the longitude and latitude into user behavior records of other interface types of the UE so as to represent the geographic position of the user.
The positioning algorithm used by the data acquisition system for positioning calculation can adopt triangular field intensity positioning or TA + AoA positioning. However, if the user MR samples are less, the UE _ MR user behavior record in the cell cannot be found, and then the latitude and longitude of the base station in the engineering parameters (abbreviated as "working parameters") are backfilled in the user behavior records of other interface types for fuzzily representing the geographic location of the user.
However, the calculation accuracy is poor whether the triangular field intensity positioning algorithm or the TA + AoA positioning algorithm is adopted.
Based on this, in various embodiments of the invention: acquiring navigation system information of UE; and preferentially taking the acquired navigation system information as the position information of the UE, and backfilling the position information into user behavior records of various types of interfaces corresponding to the UE.
Example one
The positioning method provided by the embodiment is applied to an LTE data acquisition system, and as shown in fig. 1, the method includes the following steps:
step 101: acquiring navigation system information of UE;
specifically, business data are collected from an S1-U interface;
and performing Deep Packet analysis (DPI) on the collected service data to acquire the navigation system information.
Here, the navigation system information: the information may be Global Positioning System (GPS) information, BeiDou Navigation Satellite System (BDS) information, or the like.
In practical applications, before the step is performed, the method may further include:
obtaining second position information of the UE based on positioning information in the UE measurement report user behavior record;
backfilling the obtained second position information into the UE measurement report user behavior record.
The measurement report user behavior record is a user behavior record generated based on a measurement report message reported by the UE.
Here, the purpose of backfilling the obtained second location information into the UE measurement report user behavior record is:
when navigation system information cannot be obtained subsequently, the second location information may be adopted as location information in a user behavior record of each type of interface of the UE.
In practical applications, the measurement report user behavior record may also be referred to as UE _ MR user behavior record.
Based on the positioning information in the UE measurement report user behavior record, a specific implementation process of obtaining the second position information of the UE may adopt a triangular field intensity positioning method, or may adopt a TA + AoA positioning method, etc.
Step 102: using the acquired navigation system information as first position information of the UE;
step 103: and backfilling the first position information into user behavior records of various types of interfaces corresponding to the UE.
Here, each type of interface backfilled satisfies a preset condition.
Specifically, filling longitude and latitude information corresponding to the service starting time in the user behavior record;
filling longitude and latitude information corresponding to the service ending time in the user behavior record.
In addition, position information source information can be filled in the user behavior record; the location information source information characterizes a source of location information in the user behavior record.
Here, when backfilling with navigation system information, the source information of the filled-in location information is a navigation system (such as GPS or BDS, etc.); when the position information in the UE _ MR user behavior record is used for backfilling, the filled position information source information is UE _ MR; and when the position information of the base station is used for backfilling, the filled position information source information is the engineering parameter.
In practical application, the navigation system information of the UE may not be obtained, and thus the navigation system information cannot be backfilled into the user behavior records of each type of interface as the location information of the UE, so in this case, the user behavior records of each type of interface still need to be backfilled with the location information in the UE _ MR user behavior record.
Based on this, the preset condition characterization backfill user behavior record does not comprise the UE _ MR user behavior record.
When the backfilled interface user behavior record is the S1-U interface user behavior record and the navigation system information is not acquired within a preset time period, acquiring the UE _ MR user behavior record within the preset time period;
backfilling the second position information in the acquired first UE _ MR user behavior record in the preset time period to the S1-U user behavior record; and the first UE _ MR user behavior record is the UE _ MR user behavior record at the moment closest to the end moment of the preset time period.
Here, when the UE _ MR user behavior record is not acquired within the preset time period, the location information of the base station is backfilled into the S1-U user behavior record.
Wherein the location information of the base station can be obtained from network engineering parameters.
The preset time period may be determined as needed.
When the backfilled user behavior records of various interfaces are the user behavior records of other interfaces (such as Uu, X2, S1-MME, S6a, S11, SGs interfaces and the like) except the S1-U interface, navigation system information (first position information) in the user behavior records of the S1-U interface is obtained within a preset time period, and when the navigation system information is obtained, the obtained navigation system information is backfilled into the user behavior records of other interfaces as position information; when first position information in the user behavior record of the S1-U interface is not acquired within the preset time period, acquiring the user behavior record of the UE _ MR within the preset time period;
backfilling third position information in the acquired second UE _ MR user behavior record in the preset time period into user behavior records of various types of interfaces; and the second UE _ MR user behavior record is the UE _ MR user behavior record at the moment closest to the end moment of the preset time period.
Here, when the UE _ MR user behavior record is not acquired within the preset time period, the location information of the base station is backfilled into the user behavior records of each type of interface.
Also, the preset time period used to backfill the user behavior records of other types of interfaces is set as desired.
The positioning method provided by the embodiment of the invention obtains the navigation system information of the UE; and preferentially taking the acquired navigation system information as the position information of the UE, backfilling the navigation system information into user behavior records of various types of interfaces corresponding to the UE, and preferentially using the navigation system information of the UE as the position information of the UE, so that the positioning precision can be improved.
Example two
On the basis of the first embodiment, the present embodiment takes GPS information as an example to describe in detail how to perform the positioning process.
The positioning process of this embodiment, as shown in fig. 2, includes the following steps:
step 200: based on the positioning information in the UE _ MR user behavior record, acquiring the position information of the UE, and backfilling the position information into the UE _ MR user behavior record;
step 201: analyzing the service data collected by the S1-U interface to obtain GPS information, if the GPS information can be obtained, executing step 202, and if the GPS information cannot be obtained, executing step 204;
step 202: backfilling the acquired GPS information into a position information field of the S1-U interface user behavior record, and then executing the step 203;
specifically, in practical applications, as shown in fig. 3, the user behavior record of the S1-U interface includes two pieces of time information, which are the start time of the service and the end time of the service. During backfilling, two groups of GPS information at the closest time are respectively collected corresponding to the two times, and are filled into the S1-U interface user behavior record, that is, the "longitude and latitude corresponding to the start time" and the "longitude and latitude corresponding to the end time" fields, so as to obtain the record format shown in fig. 4.
Step 203: setting a position information source field in the S1-U interface user behavior record as a GPS, and then executing a step 204;
step 204: setting the position information fields in the user behavior record of the S1-U interface to be F, indicating that the GPS information is not acquired, and then executing the step 205;
here, the location information field includes: longitude corresponding to the starting time, latitude corresponding to the starting time, longitude corresponding to the ending time, and latitude corresponding to the ending time.
Step 205: judging whether the position information fields in the S1-U interface user behavior record are all F, if so, executing the step 206, otherwise, executing the step 211;
step 206: searching whether the position information in the UE _ MR user behavior record can be searched in the time window T, if so, executing step 207, otherwise, executing step 209;
step 207: backfilling the position information in the UE _ MR user behavior record at the searched latest moment to a position information field in the S1-U interface user behavior record;
here, the filling manner may refer to fig. 4.
The latest time is the time closest to the end time of the time window T.
Step 208: setting a position information source field in the user behavior record of the S1-U interface as UE _ MR;
step 209: backfilling the position information of the base station to a position information field in the user behavior record of the S1-U interface;
here, the filling manner may refer to fig. 4.
The purpose of this step is to obscure the characterization of the geographical location of the UE.
Step 210: setting a position information source field in the S1-U interface user behavior record as a worker parameter;
step 211: searching whether the GPS information in the S1-U interface user behavior record can be searched in the time window T, if so, executing the step 212, otherwise, executing the step 214;
here, whether the GPS information can be searched can be determined from whether the location information source field is GPS.
Step 212: backfilling the position information (GPS information) in the searched user behavior record of the S1-U interface at the latest moment into the position information field of the user behavior record of other types of interfaces;
here, the latest time is the time closest to the end time of the time window T.
The filling-in manner can refer to fig. 4.
Step 213: setting a position information source field in the user behavior records of other types of interfaces as a GPS;
here, the other type of interface may be a Uu, X2, S1-MME, S6a, S11, SGs interface, or the like.
Step 214: searching whether the position information in the UE _ MR user behavior record can be searched in the time window T, if so, executing step 215, otherwise, executing step 217;
here, the latest time is the time closest to the end time of the time window T.
Step 215: backfilling the position information in the searched UE-MR user behavior record at the latest moment to position information fields in user behavior records of other types of interfaces;
here, the filling manner may refer to fig. 4.
The latest time is the time closest to the end time of the time window T.
Step 216: setting a position information source field in the user behavior record of other types of interfaces as UE _ MR;
step 217: backfilling the position information of the base station to position information fields in user behavior records of other types of interfaces;
here, the purpose of this step is to obscure the characterization of the geographical location of the UE.
Step 218: and setting the position information source field in the user behavior record of the other type of interface as the work parameter.
As can be seen from the above description, in the solution provided by the embodiment of the present invention, first, raw data of the S1-U interface is collected and analyzed to obtain GPS information (including longitude and latitude); when the GPS information is acquired, the GPS information is preferentially taken as a positioning reference of the data acquisition system and is backfilled into user behavior records of various interfaces (except for the Uu interface). Wherein,
in the backfilling process, if the GPS information cannot be obtained within a preset time period (assumed to be T), the position information obtained through the existing UE _ MR user behavior record is used as a positioning reference, and the position information is backfilled into the user behavior records (except the UE _ MR user behavior record) of various types of interfaces.
Of course, if within the range of T, neither GPS information can be found nor location information can be obtained by the existing scheme, the location information of the base station is backfilled into the user behavior records of various types of interfaces.
Meanwhile, because there are three ways to obtain the location information, in order to enable other types of interfaces (except the S1-U interface) to correctly obtain the location information, the source of the location information, such as GPS, UE _ MR, and employee id, is marked in the user behavior record to represent the source of the location information.
According to the scheme provided by the embodiment of the invention, the GPS information is preferentially used as the position information of the UE and is backfilled into the user behavior records of various types of interfaces, so that the positioning precision can be improved.
