[0064] In related technologies, machine learning methods and deep learning methods can be used to acquire user mobile information, and different methods have different applicable scopes.

[0065] Figure 3 A flowchart illustrating a method for obtaining user mobility information according to an embodiment of the present disclosure is shown. The method steps of this embodiment can be executed by a terminal or a server, or by interaction between a terminal and a server, or by a server cluster; for example, they can be executed by the methods described above. Figure 1 The server 105 in the middle executes, but this disclosure is not limited thereto.

[0066] In step S310, an analysis region is selected within the first range.

[0067] In this step, the terminal or server selects an analysis area within a first range.

[0068] In one embodiment, the first scope can be a nationwide, provincial, or municipal area. The analysis area can be areas that passengers must pass through, such as departure halls, arrival halls, and waiting halls at airports and high-speed rail stations.

[0069] In one embodiment, selecting the analysis region within the first range includes:

[0070] Within the first range, the area that the user must pass through is selected as the analysis area.

[0071] In step S320, base station cells whose coverage overlaps with the analysis area are obtained.

[0072] In this step, the terminal or server acquires base station cells whose coverage overlaps with the analysis area.

[0073] In one embodiment, acquiring base station cells whose coverage overlaps with the analysis area includes:

[0074] The gridded coverage of base station cells in the region where the analysis area is located is obtained based on the measurement report (MR) with AGPS (Assisted Global Positioning System).

[0075] Based on the gridded coverage of the base station cells in the region where the analysis area is located and the analysis area, obtain the base station cells that overlap with the analysis area.

[0076] The region where the analysis area is located can be a suitable area that includes each analysis area, such as the street or community where each analysis area is located.

[0077] In step S330, signaling data of the overlapping base station cells within a first time period is obtained.

[0078] In this step, the terminal or server obtains signaling data for the first time period of the overlapping base station cells.

[0079] In one embodiment, the data may include signaling data (4G: S1MME (interface between base station eNodeB and mobility management entity MME), 5G: N1N2 (N1 is the interface between the core network and the mobile phone, and N2 is the interface between the core network and the base station)) and MR data.

[0080] In step S340, the user's dwell information in each region of the analysis area is obtained based on the signaling data within the first time period.

[0081] In this step, the terminal or server obtains the user's residence information in each region of the analysis area based on the signaling data within the first time period.

[0082] In one embodiment, the residency information includes, for example, start time and residency time.

[0083] In step S350, the user's movement information between different areas in the analysis area is obtained based on the dwell information.

[0084] In this step, the terminal or server obtains the user's movement information between different areas in the analysis area based on the residency information.

[0085] In one embodiment, the mobility information is, for example, a user's mobility information from Beijing Airport to Shanghai Airport on a certain day.

[0086] In one embodiment, the method further includes: cleaning up users with the residency information to remove interfering users from the analysis area.

[0087] In one embodiment, cleaning up users with the residency information to remove interfering users from the analysis area includes:

[0088] Remove interfering users whose resident information exists only in one of the analysis areas.

[0089] In one embodiment, the method further includes:

[0090] Obtain measurement reports, including AGPS, within the second range for the user;

[0091] Based on the user's AGPS measurement report and artificial intelligence prediction device, the latitude and longitude of the user's measurement report without AGPS is predicted.

[0092] The second scope includes, for example, the city, community, or street where the user lives.

[0093] In one embodiment, the method further includes:

[0094] The user's movement trajectory within the second range is obtained based on the actual AGPS and predicted latitude and longitude from the user's measurement report.

[0095] The method of this disclosure will be explained in detail below with specific examples:

[0096] When users use APP (Application) services through mobile terminals, the mobile communication network periodically generates MR (Measurement Report) to assess the quality of the wireless environment. The MR includes information such as TA (Timing Advance), RSRP (Reference Signal Receiving Power), PCI (Physical Cell Identification), and FCN (Frequency Channel Number). About 2% of the MR records contain AGPS positioning information.

[0097] Currently, by utilizing big data and AI (Artificial Intelligence) technologies, the positioning accuracy of mobile networks based on MR can reach 50-100 meters (using AGPS latitude and longitude and features such as TA and RSRP in MR to build a fingerprint (feature) database, and using AI to predict the latitude and longitude of MR records).

[0098] MR data: From its generation to its collection and processing on the big data platform, the current latency is about one hour.

[0099] Signaling data: 4G signaling data (S1MME) is output in 15-minute increments with a collection delay of about 10 minutes; 5G signaling data (N1N2) is output in hourly increments with a collection delay of about 30 minutes.

[0100] Airports and high-speed railways, as transportation hubs, are among the most important scenarios for emergency service support. Statistical analysis of passenger flow in airports and high-speed railways is one of the main research topics for critical security.

[0101] Obtaining passenger data directly is difficult (due to privacy concerns, multiple ticketing channels, numerous airlines, and dynamic rescheduling), making it challenging to track passenger origins and destinations, which poses difficulties for passenger flow statistics and analysis in critical security scenarios.

[0102] This disclosure utilizes user mobile phone signaling data to identify the origin and destination of passengers at major transportation hubs such as airports and high-speed rail stations, enabling multi-dimensional statistical analysis of passenger flow at these hubs. This avoids the drawbacks of traditional methods that rely on mobile phone number location to determine migration direction, supporting enterprises in providing efficient and accurate emergency service support.

[0103] Figure 4 A basic flowchart of an embodiment of the present disclosure is shown.

[0104] This disclosure only extracts signaling data from cells whose coverage area overlaps with the defined hub area. Based on the sequential occurrence of signaling data from user mobile phones in different areas while fully considering regional overlap, it determines the transportation hubs the user has passed through and their travel direction, achieving accurate analysis of passenger flow migration at transportation hubs with minimal data. The main process is as follows:

[0105] (1) Selection and Configuration of Transportation Hub Areas: Select the area to be analyzed (polygon) on the map and define the area scene name. Configure the area type (airport, high-speed rail, etc.), province, city, area ID (Identity Document, unique code), center latitude and longitude, etc. The area may only include departure halls, arrival halls, waiting halls, and other places that passengers must pass through. If there are multiple airports, high-speed rail stations, etc. in the same city, select and define them separately. Different areas can overlap.

[0106] (2) MR latitude and longitude prediction and backfilling: A fingerprint database is constructed using records with AGPS information in massive MR data and features such as TA and RSRP in the records. Based on AI algorithm, the latitude and longitude of other records without AGPS are predicted and backfilled into the MR records.

[0107] (3) Cell coverage calculation: Rasterize the AGPS records in MR (at least one week of data), connect the coverage grids of each base station cell, and generate the coverage outline polygon (i.e., latitude and longitude point set) and cell coverage area of ​​each cell.

[0108] (4) Regional cell list and data collection: Extract cells that intersect with the configured regional range from the cell coverage data of the corresponding province and city, and the data collection department collects data according to the required cell list (currently, the S1MME data collection frequency is 15 minutes).

[0109] (5) List of region and user signaling data association: The data and signaling data of each region are associated (through cell ID) to obtain the list of user signaling data in each region (region ID, region type, encrypted MDN (MDN is an abbreviation for MSISDN, mobile user number: MSISDN: Mobile Subscriber International ISDN Number), signaling occurrence time, cell ID, etc.).

[0110] (6) Data processing: Data is collected within a time range of period (T, e.g., day) + extension period (X, e.g., 6 hours), and then sorted by user and timestamp; for each user, records with adjacent times in the same area are aggregated to obtain aggregated data (user, area ID, type, start time, stay duration, etc.); interference users in the aggregated data are removed (i.e., users who only appear in one area during the statistical period or have time overlap in overlapping areas but no other destination and the two areas are close to each other); the remaining data is used to generate a user area migration data list (MDN, A, B, start time of each segment, stay duration, interval distance) according to user migration intervals. If there are overlapping areas between the start and end points, the start / end point is determined by comprehensively evaluating factors such as distance, time, speed, area type, and stay duration (the other one is discarded).

[0111] (7) Statistical Analysis: User migration statistics (origin and destination) can be performed by region, province, city, etc., to trace user trajectories, or MR precise positioning data can be used to further analyze user travel trajectories. Based on travel history information, it is possible to distinguish between high-speed rail / airplane employees and ordinary passengers, passenger travel modes, stay duration, travel frequency, etc. (user profiling).

[0112] This disclosure extracts only cell signaling data that overlaps with the coverage area and the custom hub area. Based on the order in which signaling data from the user's mobile phone appears in different areas, and taking into full account the factors of regional overlap, it determines the transportation hubs and travel directions that the user passes through, and achieves accurate analysis of passenger flow migration at transportation hubs with as little data as possible.

[0113] The solution disclosed herein may mainly include the following modules:

[0114] (1) Transportation hub area selection and configuration module:

[0115] Select the core area of ​​the transportation hub (a place that passengers must pass through) on the map and configure the relevant parameters. The "Regional Information Configuration Table" mainly includes: Region ID (unique number, which can be in the form of area code plus serial number), Region Name, Region Type (airport, high-speed rail, etc.), Province and City of the Region and Province and City Code, Latitude and Longitude of the Region Center Point, Region Outline (a polygon in WKT format, i.e., the set of latitude and longitude points of the polygon), and Cell ID Set (cells whose coverage area overlaps with the outline of the selected region are filled in this field, in the format: Base Station ID…CellID@Base Station ID…CellID…. There can be shared cells between regions in the same city, that is, two regions overlap, and there are base station cells that can cover both regions at the same time, i.e., overlapping cells). The main data is as follows (only the key fields are listed, other fields are omitted, the same below):

[0118]

[0119] (2) MR latitude and longitude prediction and backfilling module + cell coverage calculation module:

[0120] A fingerprint database is constructed using records with AGPS information in the MR data and features such as TA and RSRP in the records. Based on AI algorithms, the latitude and longitude of other MR records without AGPS information are predicted and backfilled into the MR. The AGPS records in the MR are rasterized (data from at least the most recent week), and the coverage raster of each base station cell is connected to generate the coverage outline polygon of each cell.

[0121] (3) List of regional communities and data collection:

[0122] From the cell coverage data of the corresponding province and city, extract the cells that intersect with the configured area. The data collection department collects relevant signaling data (including 4G and 5G signaling data (S1MME and N1N2) and MR data) according to the required cell list (province, city, cell ID (base station ID + cell ID (CELLID))). The signaling data content includes at least the following information: data date (YYMMDDHH), user number, service occurrence timestamp, cell ID, user number, user's home province, etc.

[0130] The data for that time range is extracted from the "Regional and User Signaling Data Association List" using a statistical period (T, e.g., days) + extension period (X, e.g., 6 hours) pattern for statistical analysis. The extracted data is then sorted by user and timestamp, as shown in the following example:

[0131] Example of a list of regions and user signaling data associations.

[0132]

[0133] For each user, records of adjacent times within the same area are aggregated to obtain "User Travel Trajectory Statistics". Key information includes: date, user number, area ID, area type, start and end times (earliest and latest timestamps in the area), duration of stay (latest timestamp - earliest timestamp, unit: minutes / second), number of records, etc. An example is shown below:

[0134] User travel trajectory statistics

[0135]

[0136] Note: "Interval" is an abbreviation for the area between regions.

[0137] Remove interfering users from the aggregated data (staff members and passersby within the region), i.e., delete users who appear only in one region during the statistical period, or users who appear in two adjacent regions of different types with overlapping data (the two regions are close in distance but different in type, such as a high-speed rail station and an airport), and whose appearance times overlap but have no other records in distant regions. See MDN2 in the table above. The rule for determining proximity is: the distance between the center points of two regions is less than 3 kilometers; anything exceeding 3 kilometers is considered distant. The 3-kilometer threshold is a configurable parameter that can be adjusted according to actual conditions (only a few cities nationwide have high-speed rail stations and airports bordering each other, belonging to this type of overlapping region; in such cases, the center points of each region need to be determined based on the actual region selection area before calculating the distance between overlapping regions).

[0138] Generate a user area migration data list (MDN, departure station A, arrival station B, start time of each segment, duration between stations, distance between stations, mode of transportation, etc.) based on the remaining data according to user migration intervals. Only user data that has migrated within period T is stored. Period X is used to determine whether users have moved within period T. If a user belongs to period X but not period T, they are not saved, and these users are saved in the next period T.

[0139] Special case handling:

[0140] (1) AAB model: If there is an overlapping area at the starting point and no overlapping area at the ending point, then the record with the same type as the starting area is directly matched using the type of the ending area (the record with a different type of area is discarded and does not need to be matched) to generate the user migration record.

[0141] (2) ABB model: If there is an overlapping area at the destination but no overlapping area at the starting point, then the starting point area type is directly matched with the destination area type, the other record with a different area type is discarded, and a migration record is generated.

[0142] (4) AABB model: If there is an overlap between the starting and ending areas, the starting / ending area is determined by comprehensively evaluating factors such as inter-station distance, inter-station duration (the last timestamp of leaving the previous station minus the earliest timestamp of entering the next station, in minutes or seconds), and inter-station speed (inter-station distance / inter-station duration, in kilometers / hours) (discarding the other one). For example, if the inter-station distance exceeds 300 kilometers and the inter-station speed exceeds 400 kilometers / hour, both area types can be regarded as airports; otherwise, they are high-speed rail. Specific parameter thresholds can be configured and adjusted according to the actual situation.

[0143] (5) ABBC model: This model has no overlapping areas at the starting point, overlapping areas in the middle, and no overlapping areas at the ending point. The starting point and ending point have different area types, while the middle point has two area types. In this case, the area type from the starting point to the middle point is used, and the area type from the middle point to the ending point is used. Transfer records between different area types at the middle nodes are added, and the mode of transportation is filled in as "transfer". In this case, three migration records need to be saved, namely AB, BB, and BC.

[0144] The ABAB (BABA) model involves users continuously switching between overlapping areas (A and B belong to the same city, and the distance between areas is less than a threshold). If no subsequent area records are available, the user is considered to be either a worker or a passerby in that overlapping area. If subsequent area records are available, the process can be handled according to the four models mentioned earlier. Records of switching between areas are compressed into two records, one for A and one for B, and then processed according to the subsequent trajectory using models 1-4.

[0145] The generated list of user migration records is shown below (main fields are extracted).

[0146] User migration record list (sample)

[0147]

[0148] (6) Statistical analysis:

[0149] User migration statistics (origin and destination) can be performed by region name, province, city, mode of transportation, etc., to trace user trajectories, or further analyze user travel trajectories using MR precise positioning data. Based on user travel history information, it is possible to distinguish between high-speed rail / airplane crew members and ordinary passengers, passenger travel modes, stay duration, travel frequency, etc. (user profiling).

[0150] A graph database can be used to store user travel trajectories. Nodes include: region name (high-speed rail / airport, attributes include: province, city, area code, etc.) and user number (attributes include: age, gender, province, city, etc.). Directed edges are constructed based on user destinations (edge ​​attributes include time, mode of transportation, stay duration, etc.), and undirected edges are constructed based on high-speed rail lines. This facilitates graph retrieval, tracing user trajectories, and statistical analysis of nodes.

[0151] The main advantages and benefits of this disclosure are:

[0152] Based on the customizable area selection of cells, this method offers strong operability and controllable data scale: Based on the current number of airports and high-speed rail stations (200+ high-speed rail stations, 700+ bullet train stations, and 200+ airports), this method selects cells that can actually cover the selected area (where passengers must pass through). Then, it collects data according to the cell list and updates the cell list regularly based on the addition or change of the area, making the scale of collected and processed data controllable and easy to operate (currently, the group's data center gathers XDR+MR data from all provinces in China and can customize data according to the cell list, with an XDR sampling frequency of 15-minute granularity).

[0153] Accurately identify the origin and destination of passengers in a region: Combining the characteristics of "closed" transportation between regions by high-speed rail and airplanes, the method disclosed in this paper can effectively eliminate interference data, accurately identify the origin and destination of passengers in each region, and further distinguish between ordinary passengers and crew members by combining historical data.

[0154] This publicly available method, based on user mobile phone signaling data, leverages the point-to-point closed-loop transportation characteristics of high-speed rail and airports—where passengers who board the train / plane will inevitably appear at the next station, with no passengers being dropped off midway. This allows for easy elimination of regional staff and transient passengers, enabling precise identification of passenger origins and destinations at major transportation hubs such as airports and high-speed rail stations. It facilitates multi-dimensional statistical analysis of passenger flow at these hubs, as well as user profiling and trajectory tracing. The publicly available method utilizes a controllable data range and scale (over 200 high-speed rail stations nationwide, up to 40 airports, and over 10,000 base stations, equivalent to the scale of a local network), making it highly operable.

[0155] The main technical points are as follows:

[0156] (1) Method for identifying the origin and destination of passengers in the region: Make full use of the characteristics of high-speed rail and air transport, long-distance point-to-point transportation, no passengers getting on or off in the middle (unlike car transport), and accurately determine the origin and destination of passengers by integrating the signaling information of various transportation hubs and according to the time sequence.

[0157] (2) Regional passerby removal method: Based on signaling cell-level data collection, the output frequency is high and fast (and the source end does not need secondary processing, unlike MR data which requires MDN backfilling and latitude and longitude prediction, etc.). Furthermore, due to the point-to-point transportation characteristics, regional passersby will not appear in other areas, which facilitates the removal of interference data.

[0158] (3) Overlapping area arrival and departure identification mechanism: By comprehensively evaluating and analyzing factors such as the type of area the passenger passes through, the distance between sections, and the duration of the section, interference factors are eliminated and the compatibility of the method is enhanced.

[0159] (4) Output data facilitates multidimensional statistical analysis: Saves the arrival and departure information of each user segment, which facilitates multidimensional statistical analysis of passenger migration and regional passenger flow according to region, user, province, city, region type, etc., and can trace user trajectory, etc.
