The mobile terminal generates a measurement signaling when services such as attachment, location update, calling and paging occur in a mobile communication network, the positioning system can acquire the measurement signaling in real time, and the measurement signaling is analyzed on line to obtain location information of the mobile terminal, information acquisition time and the like, wherein the information acquisition time can be the time for acquiring the location information of the mobile terminal or the time for acquiring the measurement signaling.
The mobile communication network may be a Global System For mobile communications (GSM) network, a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, a Long Term Evolution (LTE) network, a fifth Generation mobile communication (5Generation, 5G) network, and other existing networks For mobile terminal communication. But also a sixth generation mobile communication network.
Taking a mobile communication network as an LTE network as an example, an access network device in the LTE network is an evolved node B (eNB), and a core network element of the LTE network includes: a Mobility Management Entity (MME), a packet data network gateway (P-GW), a service gateway (S-GW), a Home network Server (HSS), and the like.
The HSS is used for storing user subscription information, including user service information, authentication information, position management information and the like; the MME is responsible for functions of terminal access control, mobility management, session management, network element selection (such as S-GW/P-GW selection) and the like. Therefore, the positioning system can acquire the location information of the mobile terminal through the location tracking signaling in the HSS, the MME or the HSS.
Taking the mobile communication network as a 5G network as an example, the access network device of the 5G network may be a new air interface base station (NRnodeB, gNB), a new generation evolved base station (NG-eNB), a Central Unit (CU), a Distributed Unit (DU) in separate forms, such as a gNB, a transmission point (TRP), a Transmission Point (TP), or other nodes.

The field angle of the camera is approximately conical, and the field angle of the camera is adjusted to be overlapped with the radiation angle of the antenna of the sector, so that the shooting range of the camera is overlapped with the coverage range of the sector.
In the embodiment of the present application, the overlapping of the shooting range of the camera and the coverage range of the sector means: the shooting range of the camera and the coverage range of the sector are partially crossed in space. The main principles of camera deployment are: the shooting range of the camera and the coverage range of the sector are crossed in space to the largest extent possible. By the application, the relevance between the mobile terminal and the object can be found through the monitoring platform.

s101, the monitoring platform obtains information of at least one first mobile terminal from the positioning system according to the first time when the target object enters the target shooting range.
The first mobile terminal is a mobile terminal accessed to the target sector within the first time period, and the mobile terminal accessed to the target sector is a mobile terminal establishing wireless connection with a cell corresponding to the target sector. The target shooting range overlaps with the coverage range of the target sector, and the first time belongs to a first duration. The target shooting range may be composed of shooting ranges of one or more cameras.
When the monitoring platform receives a monitoring request for a target object, the monitoring platform is triggered to acquire information of the first mobile terminal from the positioning system, at the moment, the monitoring platform only has an image of the target object and does not know other information of the target object, wherein the image comprises a picture and/or a video.
Illustratively, the monitoring platform sends a first request message to the positioning system, where the first request message is used to request to acquire information of a mobile terminal that accesses the target sector within a first time period, and the positioning system sends a first response message to the monitoring platform according to the first request message, where the first response message includes information of the at least one first mobile terminal.

And after receiving the first request message, the positioning system determines the starting time and the ending time of the first time according to a preset determination rule and the first time. For example, the first time is moved forward by 10 milliseconds (ms) to obtain a start time of the first duration, and the first time is moved backward by 10ms to obtain an end time of the first duration, or the first time is moved forward by 10ms to obtain a start time of the first duration, and the first time is moved backward by 5ms to obtain an end time of the first duration.
In this system, the positioning system stores a correspondence relationship between the imaging range of the camera and the sector, and the imaging range of the camera having the correspondence relationship overlaps with the coverage of the sector. The correspondence relationship includes the ID of the shooting range and the ID of the sector, and may further include one or more of the following information: position information, orientation, angle of view information, and imaging distance of the camera corresponding to the imaging range, position information of the base station in which the sector is located, radiation angle of the sector, and the like.
The position information of the camera may be longitude and latitude of the position of the camera, or longitude, latitude and altitude information of the position of the camera, and the altitude information may be altitude or floor information. In general, when a camera is installed outdoors, the position information of the camera is longitude and latitude, and when the camera is installed indoors, the position information of the camera includes longitude, latitude, and altitude information. The location information of the base station is the longitude and latitude of the location of the base station.

And after receiving the first request message, the positioning system determines a first time length according to the first time and determines a first mobile terminal according to the first time length and the ID of the target sector.
In another implementation, the first request message includes an ID of the target sector and a first duration.
In the method, the ID and the first duration of the target sector are determined by the monitoring platform, the specific determination method refers to the description of the implementation method, and the positioning system determines the first mobile terminal according to the ID and the first duration of the target sector.
S102, the monitoring platform determines a target mobile terminal related to the target object according to the information of the first mobile terminal.
In the embodiment of the present application, a mobile terminal having a relationship with a target object is referred to as a target mobile terminal. The target mobile terminal associated with the target object may be a mobile terminal carried by the target object, for example, the target object is a specific person, and the target mobile terminal is a mobile phone carried by the specific person. For example, the target object is a box of goods and the target mobile terminal is a tablet computer secured to the box of goods. By applying the embodiment of the application, the relevance between the mobile terminal and the object can be found through the monitoring platform, and after the monitoring platform associates the mobile terminal with the target object, the information of the target object can be obtained according to the information of the mobile terminal.
The monitoring platform associates the target mobile terminal with the object: and the monitoring platform establishes association between the monitoring data of the target object shot by the camera and the information of the target mobile terminal.
In this embodiment, the monitoring platform may determine the target mobile terminal associated with the target object by:
in the first mode, when the number of the first mobile terminals is one, the monitoring platform determines that the first mobile terminal is the target mobile terminal.
Because the target shooting range is overlapped with the coverage range of the target sector, if the camera in the target shooting range shoots the target object at the first time and only one mobile terminal enters the target sector in the first time, the mobile terminal is the mobile terminal carried by the target object, and the monitoring platform associates the mobile terminal with the target object.
For example, the target object is a, and assuming that the object a enters the shooting range of the camera 1 at time t1, the monitoring platform tracks the object a. If the positioning system returns to the monitoring system before and after the time ti (namely the first time duration), only one mobile terminal A accesses the sector 1, wherein the coverage area of the sector 1 is overlapped with the shooting range of the camera 1, the mobile terminal A is proved to be the mobile terminal carried by the object a, and the object a is associated with the mobile terminal A.
And secondly, when the number of the first mobile terminals is multiple, the monitoring platform acquires the state information of the multiple first mobile terminals after the first time period from the positioning system, and determines the target mobile terminal associated with the target object according to the state information of the target object and the state information of the multiple first mobile terminals.
For example, when the monitoring platform determines that the target object leaves the target shooting range at the second time according to the state information of the target object, the monitoring platform determines whether the plurality of first mobile terminals leave the target sector within the second time length according to the state information of the plurality of first mobile terminals, where the second time length is the second time length. And if only one first mobile terminal in the plurality of first mobile terminals leaves the target sector within the second time length, the monitoring platform determines the first mobile terminal leaving the target sector within the second time length as the target mobile terminal.
Or when the monitoring platform determines that the target object is always located in the target shooting range according to the state information of the target object, the monitoring platform judges whether the plurality of first mobile terminals leave the target sector according to the state information of the plurality of first mobile terminals, and if only one first mobile terminal in the plurality of first mobile terminals does not leave the target sector, the monitoring platform determines that the first mobile terminal which does not leave the target sector is the target mobile terminal.
When the target mobile terminal carried by the target object and other mobile terminals leave the target sector and enter another sector at the same time, the method is adopted to continuously search the target mobile terminal associated with the target object, and the like is repeated until the monitoring platform determines the target mobile terminal associated with the target object.
In this embodiment, the monitoring platform obtains information of at least one first mobile terminal from the positioning system according to a first time when the target object enters a target shooting range, where the first mobile terminal is a mobile terminal that accesses a target sector within a first time period, the target shooting range overlaps with a coverage of the target sector, and the first time belongs to the first time period, and the monitoring platform determines the target mobile terminal associated with the target object according to the information of the first mobile terminal. The monitoring platform can quickly and accurately acquire the information of the mobile terminal carried by the tracked target object by combining the position information of the target object, the position information of the mobile terminal and the time information.
Fig. 5 is a flowchart of a monitoring method for a target object according to a second embodiment of the present application, and as shown in fig. 5, the method according to the second embodiment includes the following steps:
s201, when the target object moves in the plurality of shooting ranges, the monitoring platform determines first displacement data of the target object in a preset time length according to pictures shot in the plurality of shooting ranges.
The target object may move in a plurality of shooting ranges with the mobile terminal, each shooting range is composed of shooting ranges of one or more cameras, each shooting range corresponds to a sector, and the shooting ranges with corresponding relations overlap with the coverage of the sectors.
The monitoring platform determines, according to the pictures shot in the multiple shooting ranges, first displacement data of the target object within a preset time length, where the preset time length is different from the first time length in the first embodiment, where the preset time length may be specified by a user through the monitoring platform, for example, if the user wants to query monitoring data of the target object at 8 o 'clock to 9 o' clock in XX month XX in XXXX year, the preset time length is 8 o 'clock to 9 o' clock in XX month XX year in XXXX year.
The first displacement data comprises time when the target object enters each shooting range and time when the target object leaves each shooting range, a first motion track formed by the shooting ranges through which the target object sequentially passes can be obtained according to the time sequence, and the first motion track is formed by the shooting ranges through which the target object passes according to the sequence.

The second displacement data comprises time when the mobile terminal enters each sector and time when the mobile terminal leaves each sector within a preset time length, and a second motion track formed by sectors passed by the mobile terminal in sequence can be obtained according to the time sequence, wherein the second motion track is formed by the sectors passed by the mobile terminal in sequence.
The shooting range of the camera is overlapped with the coverage range of the sector, so that a first motion track of the target object in the preset time is matched with a second motion track of the target mobile terminal in the preset time, and motion track matching means that the shooting range corresponding to the sector through which the second motion track passes is the same as the shooting range through which the first motion track passes, or the sector corresponding to the shooting range through which the first motion track passes is the same as the sector through which the second motion track passes.
When the positioning system determines whether the first displacement data matches the second displacement data, it may first determine whether the first motion trajectory matches the second motion trajectory, and if only the second motion trajectory of one mobile terminal matches the first motion estimate of the target object within a preset time period, determine that the mobile terminal is the target mobile terminal.
If the second motion tracks of the plurality of mobile terminals are matched with the first motion track of the target object within the preset time length, the positioning system can determine the target mobile terminal according to the time when the plurality of mobile terminals enter and leave each sector and the time when the target object enters and leaves each shooting range. And if the similarity between the time when a certain mobile terminal enters and leaves each sector and the time when the target object enters and leaves each shooting range is highest, determining that the mobile terminal is the target mobile terminal.
Optionally, the positioning system may not form the first motion trajectory and the second motion trajectory, replace each shooting range in the first displacement data with a corresponding sector according to a corresponding relationship between the shooting range and the sector, then calculate a correlation between the first displacement data and the second displacement data of each mobile terminal, and use the mobile terminal corresponding to the second displacement data with the highest correlation as the target mobile terminal.

In the method, the positioning system sends the acquired second displacement data of the mobile terminal within the preset time length to the monitoring platform, and the monitoring platform compares the first displacement data with the second displacement data of the at least one mobile terminal to determine the target mobile terminal. The method for determining the target mobile terminal by the monitoring platform is the same as the method for determining the target mobile terminal by the positioning system in the foregoing manner, and details are not repeated here.
Optionally, the first request message further includes information of a plurality of shooting ranges, and correspondingly, the at least one mobile terminal is a mobile terminal in a plurality of sectors corresponding to the plurality of shooting ranges, where each shooting range corresponds to one sector. The first request message carries information of a plurality of shooting ranges, so that the positioning system determines a plurality of sectors corresponding to the plurality of shooting ranges according to the information of the plurality of shooting ranges, and then determines the mobile terminal from the plurality of sectors according to the preset time length. Therefore, the positioning system only returns the second displacement data of the mobile terminals in the plurality of sectors within the preset time length to the monitoring platform, so that the data volume returned by the positioning system to the monitoring platform is reduced, and the resources are saved.
