The cell engineering parameter information comprises engineering parameters of a cell, including cell marks, neighbor cell information, transmitting power, coverage area, base station information, antenna parameters (antenna height, longitude and latitude, antenna direction angle, downward inclination angle) and the like. The cell engineering parameter information can be used for quickly framing the mobile network area mapping of the disaster area and the preliminary screening of the terminal.

In some embodiments, the MRO can accurately obtain the GSM neighbor cell confidence of the cell, reduce mismatch and missed neighbor cell, improve the enhanced single wireless voice call continuity (Enhanced Single Radio Voice Call Continuity, eSRVCC for short) handover success rate, and improve the VoLTE network of the user. For example: after the network side starts MRO measurement, according to the MRO analysis field, finding that a neighbor relation is not added between a certain cell and the neighbor network, the neighbor relation can be added as a neighbor relation, and after the neighbor relation is added, the SRVCC switching success rate reaches a higher level.
Minimization of drive tests (minimization of drive-tests, MDT) is a drive test function introduced by the LTE system, a global positioning function is required to be started for acquisition of MDT data by a terminal, and when the terminal starts the positioning function and supports the MDT function, MDT data comprising terminal position information can be reported to a base station. Since the MDT data includes not only the MR data information but also the latitude and longitude information determined by the global positioning function, such as the latitude and longitude of the terminal.

Step S102, determining the space-time track of the terminal based on the candidate data.
In order to improve the calculation speed and reduce the consumption of resources, the space-time trajectory of the terminal is the space-time trajectory of the terminal from a preset time period before the occurrence of a disaster to the current time. For example, a terminal space-time trajectory of the terminal from 2 hours before the occurrence of the disaster to the current time is acquired.
In some embodiments, the construction of the space-time track is performed on the terminal which appears in the disaster area from N hours before the disaster to the current time, and the space-time track of the terminal is obtained. It should be noted that, the embodiment of the present application may also construct a space-time trajectory of a terminal outside the disaster area.
In some embodiments, the spatio-temporal trajectory of the terminal includes one or more of a set of terminals in a specified cell, a start time of a mobile event, a mobile network cell identification, cell latitude and longitude information, terminal latitude and longitude information, a data source, and a position determination result.
The spatio-temporal trajectory of a terminal may be recorded by the following fields:
{msisdn,starttime,cell_id,cell_lon,cell_lon,gps_lon,gp s_lat,data_source,is_in_region}
wherein Msisdn is a telephone number, and after the cell is defined, telephone numbers of terminals which appear in the cell from N hours before the occurrence of the disaster to the current time, wherein the number of the cells can be one or more, and telephone numbers of all terminals which appear in the cell can be used as terminal space-time track data.

For example, the start time is the disaster time pushed forward for 3 hours to the current time. The embodiment of the application does not limit the type of the movement event.
The cell_id is a mobile network cell identifier, and all cells in a disaster area and all cells in a buffer area in the disaster area can be used as cells in a space-time track of a terminal. The cell identity is the identity of a cell, and different cells can be distinguished according to the cell identity.
The buffer area refers to a geographic area which is a certain distance away from the disaster affected area.
In some embodiments, the mobile network cell identity refers to an identity of each mobile network cell within a disaster area and a buffer area, the buffer area referring to an area at a preset distance from the disaster area.

In some embodiments, the terminal latitude and longitude information is latitude and longitude information determined by a satellite positioning system.
The data_source records the source of the data, such as data sources including, but not limited to, MRO, MDT, etc.
The is_in_region is used for giving out whether the time control track is in the disaster area and the buffer area, and can be judged by positioning data firstly when judging, and can be judged by the longitude and latitude of the cell if no positioning data exists.
Step S103, determining a trapped person list based on the space-time track of the terminal.

Secondly, after the disaster occurs, the terminal enters the disaster-stricken area and the buffer area, and the terminal stays in the disaster-stricken area and the buffer area all the time, and the maximum moving position in the disaster-stricken area and the buffer area is smaller than the preset distance. For example, a terminal stays in a disaster area and a buffer area all the time, and the maximum moving position in the area is less than 30 meters.
And the users corresponding to the terminals are listed as a trapped person list.
Step S104, determining the position of the trapped person based on the trapped person list and the space-time track of the terminal.
And on the basis of the space-time track of the terminal, calculating and determining the final position of the trapped person in the trapped person list. For any trapped person, only positioning data is used as a calculation basis, the positioning data are arranged in a time reverse order, a final positioning point is taken, the distance between the point and all the point positions of the preamble is calculated according to time sequence push, if the maximum distance is larger than a preset distance, the latest time point GPS is used as the final position of the user, and meanwhile, the rest points and positions are drawn on a GIS to form a space-time track.
After step S104, the trapped person positioning method further includes:
and outputting the trapped person list, the final positioning position and the positioning corresponding time of the trapped person and the empty track as target rescue data for supporting.
In some embodiments, if necessary, the person can make a call on the premise that the specific positioning position is obtained through the evaluation of the professional rescue personnel, and the trapped state confirmation, the rescue pacifying and the rescue coordination are performed in a manual communication mode.
In some embodiments, the computing model is constructed by using own data obtained from network side data of the operator, and when the positioning information of the trapped person needs to be obtained, the network side data of the operator can be input into the computing model to quickly obtain the positioning information of the trapped person.
The position of the trapped person is determined by the trapped person positioning method, important auxiliary information can be provided for rescuing the trapped person under the natural disaster, and the rescue time of the trapped person is shortened, so that the risk coefficient of the trapped person is reduced.
