For a better understanding of the present invention, the following will describe in detail the method, apparatus, device and medium for roaming user positioning according to the embodiments of the present invention with reference to the accompanying drawings. It should be noted that these embodiments are not intended to limit the scope of the disclosure of the present invention.

FIG. 1 is a schematic flowchart illustrating a method for locating a roaming user according to an embodiment of the present invention. As shown in FIG. 1 , the method 100 for locating a roaming user in this embodiment may include the following steps:

S110: Receive XDR signaling, where the XDR signaling includes user information and serving cell identification information.

In some embodiments of the present invention, the XDR signaling may refer to the XDR signaling collected from the user plane interface S1-U interface. All the XDR signaling collected on the S1-U interface in a certain geographical area will be stored in the database of the resource management system. For example, all XDR signaling collected on the S1-U interface collected in a certain province will be stored in the same database.

In some embodiments of the present invention, the XDR signaling may also be collected from the control plane interface S1-MME interface.

In some embodiments of the present invention, the user information represents the identity information of the user corresponding to the XDR signaling. For example, when user A uses the service of the communication operator, an XDR signaling is generated, and the XDR signaling corresponds to user A.

In some embodiments, the user information is a Mobile Directory Number (MDN) number and/or an International Mobile Equipment Identity (IMEI) of a mobile communication device carried by the user.

In some embodiments of the present invention, the serving cell refers to the cell to which the user is connected in real time when the XDR signaling is generated. Exemplarily, if user A connects to base station B, an XDR signaling is generated. Then the XDR signaling includes the identification information of base station B.

In some embodiments, the serving cell identification information may be the number of the cell.

S120: Determine whether the user corresponding to the user information is a roaming user.

In some embodiments of the present invention, a roaming user refers to a mobile communication user outside the user's home location.

In some embodiments of the present invention, when the user information includes the MDN number, S120 specifically includes S121 to S123:

S121, extract the HLR identification code from the MDN number.

In S121, the MDN number may also be called a mobile phone number, and the specific structure is as follows: CC+MAC+H0H1H2H3+ABCD.

Among them, CC represents the country code, such as 86; MAC represents the mobile access code, which can distinguish the operator, such as 139; H0H1H2H3 represents the HLR identification code, which can also be called the regional identification code, which can indicate the province to which the user belongs, which is determined by the mobile operator. Uniform allocation, for example, 0010 means that the user belongs to province A; ABCD means the mobile subscriber number, which is allocated by each HLR.

In some embodiments, the province to which the user belongs represents: the province where the user's mobile phone number is registered. For example, if a user registers a mobile phone number in province A, the user belongs to province A.

S122, compare the HLR identification code with the preset local HLR identification code.

In some embodiments, the local HLR identification code is pre-stored in the HLR device or the HSS device. For example, an HLR device in a province will record the HLR ID assigned to that province.

In some embodiments, after the user's HLR identification code is extracted, the local HLR identification code may be extracted from the HLR device or the HSS device to determine whether the local HLR identification code is the same as the user's HLR identification code.

S123, according to the comparison result, determine whether the user is a roaming user.

In some embodiments, if the user's HLR identification code is consistent with the preset local HLR identification code, the user is a local user. If not, the user is a roaming user.

For example, the local HLR identifiers recorded in the local HLR device include: 1111, 1112 and 1122, the user's HLR identifier is 1234, the user's HLR identifier is different from the local HLR identifier, and the user is a roaming user.

In this embodiment, whether the user is a roaming user can be quickly and accurately determined according to the MSN code in the XDR signaling.

S130, if the user is a roaming user, determine the location information of the user based on the serving cell identification information and the preset correspondence between the serving cell identification information and the location information.

In S130, the location information corresponding to the serving cell identification information is determined as the location information of the user.

According to the roaming user positioning method, device, device, and medium in the embodiment of the present invention, the acquired XDR signaling includes serving cell identification information and user information. The corresponding relationship between the serving cell identification information and the preset serving cell identification information and the location information determines the location information of the user. Since the location of the user is determined according to the preset correspondence between the identification information of the serving cell and the location information, the positioning accuracy can be refined to the dimension of the cell, thereby improving the positioning accuracy.

In some embodiments of the present invention, the preset correspondence between the identification information of the serving cell and the location information can be queried in the cell work parameter data cluster.

In some embodiments, the cell engineering parameter data cluster includes the engineering parameter data of a plurality of cells.

Wherein, the work parameter data of each cell includes: the identification information of the cell and the longitude and latitude information of the cell.

At this time, the specific implementation of S130 includes: according to the identification information of the serving cell in the XDR signaling, matching the cell whose identification information is the same as the identification information of the serving cell in the cell working parameter data cluster, determining the cell as the serving cell, and The latitude and longitude information of the cell is determined as the location information of the user.

Exemplarily, the specific implementation form of the cell work parameter data cluster is shown in Table 1. If the identity information of the cell A is the same as the identity information of the serving cell, the corresponding location a may be determined as the location information of the user.

Table 1

Identification information of cell A Identification information of cell B Identification information of cell C position a position b position c

In some embodiments, in addition to this, the working parameter data of each cell may further include one or more of the following working parameter data: the home scenario of the cell, the coverage type of the cell, and the name of the cell.

Wherein, the attribution scene of the cell may be divided according to factors such as the installation scene, signal coverage or usage scene of the cell. For example, the home scene of the cell may include: a street, a station, and the like.

Cell coverage types include: macro base stations installed outdoors and micro base stations installed indoors.

The cell name indicates the Chinese name for the cell. For example, XX hotel base station.

By means of the embodiment of the present invention, after finding the working parameter data of the serving cell in the cell working parameter data cluster, various specific information of the serving cell can be obtained.

In some embodiments of the present invention, in order to further improve the positioning accuracy of the user, the method 100 for positioning the roaming user further includes:

S140, using the user's test report (Measurement Report, MR) data to calibrate the user's location information.

In S140, according to the MR data, the longitude distance and the latitude distance of the user from a certain base station can be obtained. Therefore, after the longitude and latitude coordinates of the base station are obtained, the longitude and latitude coordinates of the user can be obtained by combining the longitude and latitude distances of the user from the base station.

In some embodiments of the present invention, the XDR signaling acquired in S110 includes the XDR recording the longitude and latitude information of the user.

In order to further improve the positioning accuracy for the user, the positioning method 100 for the roaming user further includes S151 and S152:

S151 , based on the OTT positioning algorithm, parse out the longitude and latitude information of the user from the XDR signaling.

In some embodiments, during the process of using the APP on the smart phone, many APPs will acquire the latitude and longitude information of the mobile phone in real time, for example, calling a global positioning system (Global Positioning System, GPS) service, or calling a positioning software development kit (Software Development Kit) Kit, SDK) to initiate a positioning request.

Therefore, XDR signaling containing location information can be obtained from the control plane interface S1-MME interface and/or the user plane interface S1-U interface. And parse out a piece of longitude and latitude information from the acquired XDR signaling as the longitude and latitude information of the user.

S152, using the latitude and longitude information of the user to calibrate the location information of the user.

In S152, since the accuracy of the user's location information obtained through the OTT positioning algorithm is high, the obtained user's latitude and longitude information can be used to replace the user's location information obtained in S130, thereby improving the accuracy of user positioning.

In some embodiments of the present invention, the XDR signaling also records multiple key data that can reflect the user's communication service usage in a certain period of time:

The user's traffic usage, the APP used by the user, and the network-aware Key Quality Indicators (Key Quality Indicators) KQI value, etc. For example, how much traffic was used by the user during the time period from 14:40:50 to 14:41:00.

In the embodiment of the present invention, the specific situation of the user can be analyzed in combination with the working parameter information of the serving cell and the key data recorded in the above-mentioned XDR signaling. The following will be divided into three embodiments for specific description respectively.

In the first embodiment, the XDR signaling further includes the user's traffic usage, and the roaming user positioning method 100 further includes:

Determine the traffic usage of the user in the home scenario of the serving cell.

Exemplarily, the traffic usage of users in different scenarios such as stations and schools can be analyzed.

In this embodiment, by summarizing the method, the user's traffic usage in different attribution scenarios can be analyzed, and the relationship between the user's traffic usage and the change of the attribution scenario can be obtained. In this way, the changes of user service usage in different attribution scenarios can be analyzed more accurately and finely.

It should be noted that the present invention can further distinguish the traffic usage of local users and roaming users.

It should also be noted that, in this embodiment of the present invention, the traffic usage type of the user in different attribution scenarios may be further determined. For example, traffic usage types may include data traffic, call traffic, video traffic, and the like.

In the second embodiment, when the XDR signaling further includes the APP used by the user, the roaming user positioning method 100 further includes:

Determine the APP used by the user in the home scenario of the serving cell.

In this embodiment, the user's preferred APP types in different attribution scenarios can be summarized. For example, in natural scenic spots, users prefer to use map apps. In this way, the user's preference for using the APP in different attribution scenarios can be analyzed more accurately and finely.

It should be noted that the present invention can further distinguish the usage preferences of local users and roaming users on the APP.

In the third embodiment, when the XDR signaling further includes the KQI value, the roaming user positioning method 100 further includes:

Based on the KQI value, the network perceived quality of the user in the home scenario of the serving cell is determined.

In one embodiment, the packet delay duration recorded in the XDR signaling may be selected as the KQI value.

By selecting the packet delay time as the KQI parameter, the network response level between the terminal side and the target server side can be reflected.

In this embodiment, the network perceived quality of the user in different attribution scenarios is determined. The scene with poor network perception quality can be further optimized according to the obtained results.

It should be noted that, in this embodiment of the present invention, the network perceived quality of the roaming user and the local user can be further distinguished.

In some embodiments of the present invention, in order to analyze the tidal situation of the flow of people in the target area (that is, the fluctuation of the flow of people in a certain period of time like tides), the positioning method 100 for a roaming user further includes:

S161 , based on the location information of the users, acquire the number of users in multiple time periods in the target area.

In S161, the target area can be customized according to the needs of the statistician. Specifically, a certain province may be selected, or a certain base station may be selected, or an area corresponding to a certain scenario may be selected. For example, square A can be chosen as the target area.

In some embodiments, taking a certain time period as an example, first, the coordinate range of the target area is determined. Then, count the number of users whose location coordinates are included in the coordinate range in multiple time periods.

Exemplarily, if it is necessary to count the number of users in shopping mall A during the period from 10:00 am to 11:00 am. The coordinate range of shopping mall A can be determined first. If the position coordinates of five users during the period from 10:00 am to 11:00 am are included in the coordinate range of shopping mall A, the number of users in shopping mall A during the period from 10:00 am to 11:00 am is 5.

It should be noted that, in S161, the number of roaming users and the number of local users in multiple time periods in the target area can be further distinguished.

S162: Determine the changing trend of the number of users in multiple time periods in the target area.

Exemplarily, after knowing the number of users of shopping mall A in multiple time periods in a day, the tidal pattern of users of shopping mall A in a day can be analyzed.

In some embodiments, a change graph or change trend of the number of users in multiple time periods in the target area may be made according to the statistical result. It is used to analyze the flow of people and tides in the target area.
