Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present specification, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the drawings in one or more embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

The embodiment of the application provides a missing person collaborative search method and device based on a network slice and an edge data center. The missing person collaborative search method based on the network slice and the edge data center can be applied to the edge data center side of the 5G network slice area and is executed by the edge data center of the 5G network slice area. The edge data center of the 5G network slicing area is an edge data center of any 5G network slicing area related to the missing person, and can comprise an edge data center of the 5G network slicing area corresponding to any place of a family opening place, a residence place, a report place or a missing place of the missing person.

Fig. 1 is a schematic flowchart of a method for collaborating missing persons based on a network slice and an edge data center according to an embodiment of the present application, where as shown in fig. 1, the process includes the following steps:

s101, acquiring a user terminal identification of the missing person according to the person information of the missing person; acquiring historical interaction information of a user terminal of a missing person and a communication base station according to a user terminal identification of the missing person;

step S102, determining a target historical travel route of a missing person according to historical interaction information, and determining person information corresponding to a person of a first identity category on the target historical travel route;

step S103, determining a search route of the missing person corresponding to each search time period according to the missing position of the missing person and the search radius corresponding to each search time period, and determining person information corresponding to the person of the second identity type on the search route of the missing person; each searching time period is a plurality of time periods which are sequentially arranged from the missing time of the missing person;

and S104, determining the person with the first identity type as a first person, determining the person with the second identity type as a second person, and sending the missing person collaborating information to the user terminal of the first person and the user terminal of the second person according to the person information of the missing person, the person information corresponding to the first person and the person information corresponding to the second person.

In this embodiment, the missing collaborative information is sent to the first person on the target historical travel route and the second person on the search route, and since the person receiving the missing collaborative information is located on the historical travel route and the search route of the missing person, the person receiving the missing collaborative information is likely to see the missing person, so that the accuracy of message sending is improved, and timely discovery of the missing person is facilitated.

Before the step S101, the method further includes: acquiring event data of the missing person submitted by a user, and extracting the person information of the missing person, the missing place of the missing person and the missing time of the missing person from the event data of the missing person; or for each target person, establishing a behavior activity model corresponding to each target person according to the interaction information between the user terminal of each target person and the communication base station, if the behavior activity data of the target person is not matched with the behavior activity model, determining the target person as a missing person, determining the activity time corresponding to the behavior activity data of the target person, which is not matched with the behavior activity model, as the missing time of the missing person, and determining the activity place corresponding to the behavior activity data of the target person, which is not matched with the behavior activity model, as the missing place of the missing person.

The user submitting the missing person event data is a person who found a case after the person is missing, and may be, for example, a family, a teacher, a friend, or the like of the missing person. Missing person event data may be understood as information provided by the person reporting the case. The person information of the missing person may include: the missing person's name, address, age, wear, appearance, and telephone number for daily use, etc. That is, after the person is missing, the name, address, age, wear, appearance, telephone number for daily use, missing place, missing time, and the like of the missing person can be acquired from the information provided by the person on note.

Or, in another method, a person with poor self-care ability and easy to lose may be defined as a target person, the behavior activity of the person with easy to lose may be modeled in advance by using the person information of the person with easy to lose and a historical common route, when the behavior activity information of the person with easy to lose does not match the behavior activity information in the model, the person with easy to lose may be defined as a missing person, and the last activity location and the activity time corresponding to the mismatching behavior activity information may be defined as the missing location and the missing time corresponding to the missing person. For example, places such as schools, home addresses and the like of children and frequent amusement park relatives are collected in advance, a behavior activity model is established according to the collected places, when the behavior activity of the children does not accord with the behavior activity in the model, the children are judged to be missing, and the finally reported activity place and activity time are determined as the missing place and the missing time corresponding to the children.

In the step S101, the user terminal of the missing person may include a mobile phone, a child phone watch, and the like. The user terminal identification may be understood as a telephone number. When the missing phenomenon of the personnel occurs, the name, the identification number and the like of the missing personnel can be obtained from the information provided by the counter, and the telephone number of the missing personnel can be obtained from the database of the operator according to the information of the name, the identification number and the like of the missing personnel. In practical application, the user terminal keeps interacting with the base station in a power-on state, so that historical interaction information of the missing person and the communication base station can be obtained from an operator database according to the telephone number of the missing person.

In the step 102, the target historical travel route of the missing person may be understood as a route where the missing person frequently walks in daily life, for example: the school route for children and the park route for the old. Persons in the first category of identity on the target historical travel route may be understood as persons who are stationary on common travel routes, e.g., merchants on the child's school route, neighbors, etc. In order to protect the privacy of individuals, when determining persons of the first identity category, persons whose location information is often distributed on the target historical travel route may be determined as the persons of the first identity category without involving specific information of the persons. The person information corresponding to the person of the first identity category may be a telephone number of the person of the first identity category, such as a telephone number of a street vendor on a route where the missing person often walks.

Historical position information of a user terminal of a missing person is obtained from historical interaction information of the user terminal of the missing person and a base station, a frequently-used walking route of the user can be determined by connecting position points of the user terminal appearing in the history, and mobile phone numbers of people on the frequently-used route, namely people such as neighbor of a merchant and the like, are obtained from a database.

The step S102 may specifically include: determining each historical travel route of the missing person within a historical time range according to the interactive information between the user terminal of the missing person and the communication base station; and selecting the route with the travel times larger than the time threshold value from the historical travel routes as a target historical travel route according to the travel times corresponding to the historical travel routes.

It can be understood that the history time range should be set to a longer time period, and when the time period is shorter, the influence of the contingency is greater, and the travel situation of the user cannot be accurately reflected. The method comprises the steps of calling all position information of a user in a time period from a database, forming a plurality of travel routes by utilizing the position information of the user terminal appearing in each period of continuous time, counting the appearing times of the travel routes, and when the appearing times of the travel routes are larger than a set threshold value, indicating that the travel routes are routes frequently used by the user. And taking the common route as a target travel route.

In step 103, the search time period is a time period after the person is lost, and both 1 hour after the person is lost and 2 hours after the person is lost can be regarded as one time period. After the person is lost, the distance from the lost person to the lost place is further and further along with the time, so that the corresponding search radius is different in different time periods, and the corresponding search range is also different. For example, when the missing time of the person is short, that is, the search time period is short, the corresponding search radius is small, and the corresponding search range is small. When the missing time of the person is long, namely the searching time period is long, the corresponding searching radius is larger, and the corresponding searching range is larger. Therefore, the search range differs for each time period, and the search route differs in different range areas. And determining a corresponding search route according to the missing point and the search radius of the person. The second identity category of people on the search route may be, for example, house vickers, security guards, vendor in the vegetable farm, scenic spot workers, etc. on the search route. The person information corresponding to the second identity category of persons may be a telephone number of the person.

The step 103 may specifically be: aiming at any one searching time period, determining a searching geographical range of the missing person corresponding to the searching time period according to the missing place of the missing person and the searching radius corresponding to the searching time period; searching each preset type of place in the geographic range by the missing person, and determining the place as a searching destination of the missing person corresponding to the searching time period; and determining a route between the missing point of the missing person and the missing person searching destination corresponding to the searching time period, and determining the route as the missing person searching route corresponding to the searching time period.

Due to the limited speed of a person walking or riding a vehicle, the search range is limited over a period of time. When the missing time of the child is 1 hour, the worst case is considered, the child is turned away, and people and pedestrain the automobile to escape, the search radius can be obtained by multiplying the maximum running speed of the automobile by the missing time of 1 hour, and the area of a circle obtained by taking the missing place as the center of the circle and the search radius as the radius is the search range. When the search range is determined in practical application, a more surplus amount can be preset, and the condition that the chance of finding a missing person is lost due to too small search radius is avoided. For example, within 1 hour of the loss, the range within the radius of 5-100 kilometers of the lost point can be determined as the search range, within 2-3 hours of the loss, the range within the radius of 100-300 kilometers of the lost point can be determined as the search range, within 4-5 hours of the loss, the range within the radius of 300-600 kilometers of the lost point can be determined as the search range, within 5-12 hours of the loss, the range within the radius of 600-1200 kilometers of the lost point can be determined as the search range.

For convenience of escape, a person dealer usually goes to a nearby train station, bus station, airport, or highway intersection for a person walking a child, and thus each predetermined type of place can be understood as the above-mentioned transit stations, and the transit stations are determined as search destinations of a missing person. And obtaining a plurality of routes by taking the missing point as the center of a circle and the traffic transfer station in the searching range as the destination, wherein the routes can be used as the searching routes of the missing person. The search ranges corresponding to different time periods are different, and the search routes correspondingly determined are also different. For example, in a time period of 1 hour after the missing, corresponding to a first search range including a bus stop and a high-speed entrance, the determined search route may include a route from the missing point to the bus stop and a route from the missing point to the high-speed entrance. And in a time period of 2 hours after the missing, corresponding to a second searching range, a railway station is additionally arranged in the second searching range, and then the searching route is also additionally provided with a route from the missing place to the railway station. Therefore, the search route is different for different time periods.

In the step 104, the collaborating information of the missing person can be generated according to the information of the missing person, the collaborating information of the missing person is sent to the first person and the second person in the form of short messages and multimedia messages, and the first person and the second person receiving the collaborating information are located on the historical travel route and the searching route of the missing person, so that the person receiving the missing collaborating information sees the missing person with high probability, the sending accuracy of the missing collaborating information is improved, and the missing person can be found in time.

The step 104 specifically includes: in each search time period, determining the current search time period in which the current moment is positioned, and determining the personnel information of the second personnel corresponding to the current search time period; generating the cooperative checking information of the missing person according to the person information of the missing person, determining the user terminal identification of the first person according to the person information corresponding to the first person, and determining the user terminal identification of the second person corresponding to the current search time period according to the person information of the second person corresponding to the current search time period; forming a personnel set by utilizing the first personnel and second personnel corresponding to the current search time period, determining first target personnel located in a 5G network slice region having an association relationship with the missing personnel in the personnel set, and determining second target personnel located in other 5G network slice regions; sending the cooperative investigation information of the missing person to the first target person through an edge data center of a 5G network slice region having an association relation with the missing person according to the user terminal identification of the first target person; and sending a collaborating instruction to the edge data centers in other 5G network slice regions, so that the edge data centers in other 5G network slice regions send the collaborating information of the missing person to the second target person according to the user terminal identification of the second target person.

The information of the missing person can be the appearance characteristics, sex, dressing, missing time, missing place, etc. of the missing person. The terminal identification may be a telephone number. In the aforementioned description, when the search route is established, the search radius is determined according to the missing time of the missing person, and the search range is determined according to the search radius. And then, taking the missing place as the center of a circle and taking the traffic transfer station in the searching range as a destination to obtain a plurality of routes, and determining the routes as the searching routes of the missing person. The search ranges in different time periods are different, the traffic transfer stations contained in the search ranges are also different, and the determined search routes are also different. When the search route changes, the second person on each route also differs. Therefore, it is necessary to determine the search time period of the current time according to the time when the missing person is missing, determine the search route according to the search time period, and then acquire the information of the second person searching the route. However, no matter how long the missing person is missing, the historical travel route of the missing person is not changed, and therefore the first person information on the historical travel route is not changed.

After determining the time period of the missing person, acquiring the telephone numbers of the persons on the historical travel route of the missing person, such as the telephone numbers of the surrounding neighbors and the telephone numbers of the business employers along the street, and then acquiring the telephone numbers of the persons on the determined search route, such as the grandfather at the gate and the mobile phone numbers of the staff at the bus station. And combining the first person on the historical travel route and the second person on the search route into a person set. Judging whether the personnel in the personnel set are in the coverage range of the edge data center for processing data, dividing the personnel in the coverage range of the edge data center for processing data into first target personnel, determining the personnel in the coverage range of the edge data center not for processing data as second target personnel, and sending the information of the appearance characteristics, the gender, the dressing, the missing time, the missing place and the like of the missing personnel to the first target personnel by the edge data center for processing data in a short message and multimedia message mode. And the edge data center for processing data carries the collaborating information on the collaborating instruction and sends the collaborating information to edge data centers of other 5G network slicing areas, and the edge data centers in the other 5G network slicing areas send the information of the appearance characteristics, the gender, the dressing, the missing time, the missing place and the like of the missing person to a second person.

The step 104 further includes: searching routes by using the target historical travel route and the missing person corresponding to the current searching time period to form a route set; acquiring response information of the first person and the second person corresponding to the current searching time period to the cooperative search information of the missing person; according to the response information, determining a first target route with the maximum missing person existence probability in the route set; and sending the missing person collaborating information to the person on the first target route again.

The historical travel route is determined, but the search route corresponding to each search time period is different, so the historical travel route is combined with the search route corresponding to each search time period to obtain a plurality of routes, and a route set is formed. The response information is feedback information made by the first person and the second person after receiving the collaborating information, and the feedback information may be, for example: a person who has seen a suspected missing person, or a person who has never seen a suspected missing person. And counting the feedback information, if the feedback information on a certain route is positive, for example, more people on a certain route feedback the people who see suspected missing people, the route can be confirmed as the route with the highest probability of existence of the missing people, namely the first target route, and the investigation information is further sent to more people on the route, so that the missing investigation information can be received by more people who are likely to see the missing people, and timely discovery of the missing people is facilitated.

The step 104 further includes: sequencing the search time periods according to the sequence of the time between the search time periods from first to last; if the first target route is determined to be obtained in the first search time period in each search time period, determining the next search time period of the first search time period in each search time period according to the sequence; and selecting a second target route from the various missing person search routes corresponding to the next search time period according to the position relation between the various missing person search routes corresponding to the next search time period and the first target route, and sending the missing person collaborative search information to the persons on the second target route at the current moment or in the next search time period.

When the feedback information is received, the route of the missing person can be roughly determined, and if the first target route is determined in the first search time period in each search time period, the next search time period of the first search time period is determined in each search time period according to the ranking, it can be understood that if the feedback is received in the 1 st hour, the rough walking route a of the missing person is determined, and the first target route is taken as a. And determining the next time period corresponding to the first hour as 2-3 hours, acquiring the search radius corresponding to 2-3 hours as 100-300 kilometers, and taking the traffic transfer station within the range of 100-300 away from the missing place as a destination to obtain a plurality of routes. For example, a B route from the missing place to a bus stop, or a C route from the missing place to a train stop. The determined route A is compared with a plurality of routes B and C, for example, if the directions of the route A and the route B are consistent, it can be determined that the route which is most likely to appear by a missing person at the next time is the route B, the route B can be used as a second target route, and then the staff on the route B can be sent with the collaborating information.
