Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the following will describe the technical solutions in one or more embodiments of this specification in conjunction with the drawings in one or more embodiments of this specification The technical solution is clearly and completely described, and obviously, the described embodiments are only a part of the embodiments in this specification, rather than all the embodiments. Based on one or more embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this document.

The embodiment of the present application provides a method and device for assisted investigation of missing persons based on network slicing and edge data centers. Among them, the method of missing person assistance investigation based on network slicing and edge data centers can be applied to the edge data center side of the 5G network slicing area and executed by the edge data center in the 5G network slicing area. The edge data center in the 5G network slicing area is the edge data center in any 5G network slicing area associated with the missing person, which can include the 5G network corresponding to any location of the missing person’s residence, residence, report, or loss Edge data centers in slicing regions.

Figure 1 is a schematic flow diagram of a missing person assistance method based on network slicing and edge data centers provided by an embodiment of the present application. As shown in Figure 1, the process includes the following steps:

Step S101. Obtain the user terminal identification of the missing person according to the personal information of the missing person; obtain the historical interaction information between the user terminal of the missing person and the communication base station according to the user terminal identification of the missing person;

Step S102: Determine the target historical travel route of the missing person according to the historical interaction information, and determine the personnel information corresponding to the person of the first identity category located on the target historical travel route;

Step S103, according to the missing person's missing location and the search radius corresponding to each search time period, determine the missing person search route corresponding to each search time period, and determine the person information corresponding to the person of the second identity category located on the missing person search route ; Each search time period is a plurality of time periods arranged sequentially since the missing person's disappearance time;

Step S104, determine the person of the first identity category as the first person, and determine the person of the second identity category as the second person, according to the missing person's person information, the person information corresponding to the first person, and the person corresponding to the second person information, and send missing person assistance information to the user terminal of the first person and the user terminal of the second person.

In this embodiment, the missing assistance investigation message is sent to the first person on the target historical travel route and the second person on the search route. Those who assist in the investigation of the news have seen the missing person with a high probability, thereby improving the accuracy of message sending and helping to find the missing person in time.

Before the above step S101, it also includes: obtaining the missing person event data submitted by the user, extracting the missing person's information, the missing person's missing place and the missing person's missing time from the missing person event data; or, for each target person , according to the interactive information between the user terminal of each target person and the communication base station, the corresponding behavior model of each target person is established. If the behavior activity data of the target person does not match the behavior activity model, the target person is determined as a missing person, and the target person The activity time corresponding to the behavioral activity data of the person that does not match the behavioral activity model is determined as the missing person’s missing time, and the activity location corresponding to the target person’s behavioral activity data that does not match the behavioral activity model is determined as the missing person’s missing Place.

The user who submits the missing person event data is the person who reports the missing person after discovering the missing person, for example, the family member, teacher, friend, etc. of the missing person. Missing person incident data can be understood as information provided by the reporting person. The missing person's personal information can include: the missing person's name, address, age, clothing, appearance and daily use phone number, etc. That is to say, after a person goes missing, the name, address, age, clothing, appearance, daily phone number, place and time of disappearance of the missing person can be obtained from the information provided by the informant.

Or, in another method, the easily lost persons with poor self-care ability can be set as the target persons, and the behaviors of these easily missing persons can be modeled in advance by using the personnel information and historical common routes of the easily missing persons. When the behavior and activity information of the missing person does not match the behavior and activity information in the model, the missing person can be judged as a missing person, and the last activity location and activity time corresponding to the unmatched behavior and activity information can be determined as the missing person’s corresponding time. The place and time of disappearance. For example, collect the children's school, the home addresses of relatives in frequented amusement parks and other places in advance, and establish a behavioral activity model based on the collected locations. When the behavioral activities of the child do not conform to the behavioral activities in the model, it can be determined that the child is missing. Determine the last reported activity location and activity time as the corresponding missing location and missing time of the child.

In the above step S101, the user terminal of the missing person may include a mobile phone, a children's phone watch, and the like. The user terminal identifier can be understood as a telephone number. When a missing person occurs, the name and ID number of the missing person can be obtained from the information provided by the reporter. According to the name and ID number of the missing person, the phone number of the missing person can be obtained from the operator's database. . In practical applications, the user terminal will keep interacting with the base station when it is turned on. Therefore, the historical interaction information between the missing person and the communication base station can be obtained from the operator's database according to the phone number of the missing person.

In the above step 102, the target historical travel route of the missing person can be understood as the route that the missing person often walks in daily life, for example: the school route of children, the park route often visited by the elderly. Persons of the first identity category located on the target historical travel route can be understood as persons who regularly appear on common walking routes, for example, merchants on the children's school route, surrounding neighbors, and the like. In order to protect personal privacy, when determining the person of the first identity category, the person whose location information is often distributed on the target historical travel route can be determined as the person of the first identity category, without involving the specific information of the person. The person information corresponding to the person of the first identity category may be the phone number of the person of the first identity category, such as the phone number of a street vendor on a route where the missing person usually walks.

Obtain the historical location information of the user terminal of the missing person from the historical interaction information between the user terminal of the missing person and the base station, and connect the location points that the user terminal has appeared in history to determine the user's usual walking route, and obtain the commonly used route from the database. The people on the route are the mobile phone numbers of people such as business neighbors.

The above step S102 may specifically include: according to the interactive information between the user terminal of the missing person and the communication base station, determine each historical travel route of the missing person within the historical time range; In the travel route, the route with the number of trips greater than the number of times threshold is selected as the target historical travel route.

It is understandable that the above-mentioned historical time range should be set to a relatively long time period. When the time period is relatively short, the impact of chance is greater and cannot accurately reflect the travel situation of the user. Retrieve all the location information of the user within a period of time from the database, use the location information that the user terminal has appeared in each continuous time to form multiple travel routes, and count the number of occurrences of multiple travel routes, when the travel route When the number of occurrences is greater than the set threshold, it indicates that the route is a frequently used route by users. Use frequently used routes as target travel routes.

In the above step 103, the search time period is the time period after the disappearance of the person, 1 hour after the disappearance of the person, and 2 hours after the disappearance of the person can be regarded as a time period. After a person goes missing, the distance between the missing person and the place of disappearance will become farther and farther as time goes by. Therefore, different time periods correspond to different search radii, and the corresponding search ranges are also different. For example, when the missing time of the person is short, that is, when the search time period is short, the corresponding search radius is small, and the corresponding search range is small. When a person is missing for a long time, that is, when the search time period is long, the corresponding search radius is larger and the corresponding search range is larger. Therefore, the search range in each time period is different, and the search routes in different range areas are also different. The corresponding search route can be determined according to the missing point and the search radius. The persons of the second identity category on the search route may be janitors, security guards, vegetable market hawkers, scenic spot staff, etc. on the search route. The personnel information corresponding to the personnel of the second identity category may be the telephone number of the personnel.

The above step 103 can specifically be: for any search time period, according to the missing person's missing location and the search radius corresponding to the search time period, determine the missing person search geographic range corresponding to the search time period; Each preset type of place within the search time period is determined as the missing person search destination corresponding to the search time period; the route between the missing person’s missing place and the missing person search destination corresponding to the search time period is determined, and the route is determined Search routes for the missing persons corresponding to the search time period.

Due to the limited speed of people walking or taking vehicles, within a certain period of time, the search range is limited. For example, when the missing time of a child is 1 hour, consider the worst case where the child is abducted and the trafficker escapes in a car. The search radius can be obtained by multiplying the maximum running speed of the car with the missing time of 1 hour, and the missing place is the center of the circle. The search radius is the area of the circle obtained by the radius, which is the search range. When determining the search range in practical applications, a relatively plentiful amount can be set in advance, so as to avoid missing the chance of finding the missing person due to too small search radius. For example, within 1 hour of being lost, the range within a radius of 5-100 kilometers of the missing point can be determined as the search range; within 2-3 hours of being lost, the range within a radius of 100-300 kilometers of the missing point can be determined as the search range; - Within 5 hours, the range within a radius of 300-600 kilometers from the missing point can be determined as the search range; within 5-12 hours of being lost, the range within a radius of 600-1200 kilometers from the missing point can be determined as the search range.

Traffickers usually go to the nearest train station, bus station, airport, or highway intersection for the convenience of escaping after abducting children. Therefore, each preset type of place can be understood as the above-mentioned traffic transfer stations, and these traffic transfer stations are determined A search destination for missing persons. With the missing location as the center and the traffic transfer station within the search range as the destination, multiple routes can be obtained, and these routes can be used as missing person search routes. Different time periods correspond to different search ranges, and correspondingly determined search routes are also different. For example, within one hour after the disappearance, corresponding to the first search range, the first search range contains a bus station and a high-speed entrance, then the determined search route may include the route from the missing place to the bus station, The route from the missing place to the highway entrance. Within 2 hours after the disappearance, corresponding to the second search range, a new train station is added in the second search range, so the search route will also add a route from the missing place to the train station. Therefore, the search routes for different time periods are different.

In the above step 104, the assisted investigation information of the missing person can be generated according to the information of the missing person, and the assisted investigation information of the missing person is sent to the first person and the second person in the form of SMS or MMS, and the first person and the second person who receive the assisted investigation information The person is located on the historical travel route and search route of the missing person, so the person who receives the missing person's assisted investigation message has a high probability of seeing the missing person, thereby improving the accuracy of the missing person's assisted investigation message and helping to find the missing person in time.

The above step 104 specifically includes: in each search time period, determine the current search time period at the current moment, and determine the personnel information of the second person corresponding to the current search time period; generate missing person assistance information according to the personnel information of the missing person, According to the personnel information corresponding to the first person, determine the user terminal identification of the first person, according to the personnel information of the second person corresponding to the current search time period, determine the user terminal identification of the second person corresponding to the current search time period; The person and the second person corresponding to the current search time period form a person set, in the person set, determine the first target person located in the 5G network slice area that has an association relationship with the missing person, and determine that the target person is located in other 5G network slice areas The second target person; through the edge data center in the 5G network slicing area associated with the missing person, according to the user terminal identification of the first target person, send the missing person assistance investigation information to the first target person; to other 5G network slicing areas The edge data center within the 5G network slice area sends an assisted search command, so that the edge data center in other 5G network slice areas sends missing person assisted search information to the second target person according to the user terminal identifier of the second target person.

The assisted investigation information of the missing person may include the missing person's appearance, gender, clothing, missing time, missing location, etc. The terminal identifier can be a phone number. As mentioned above, when establishing a search route, the search radius is determined according to the missing person's missing time, and the search range is determined according to the search radius. Taking the missing place as the center and the traffic transfer station within the search range as the destination, multiple routes are obtained, and these routes are determined as missing person search routes. The search ranges in different time periods are different, the traffic transfer stations included in the search range are also different, and the determined search routes are also different. When the search route changes, the second person on each route is also different. Therefore, it is necessary to first determine the search time period at the current moment according to the time when the missing person disappeared, confirm the search route according to the search time period, and then obtain the information of the second person who searched for the route. However, no matter how long the missing person has been missing, the historical travel route of the missing person will not change, so the information of the first person on the historical travel route will not change either.

After determining the time period when the missing person disappeared, obtain the phone numbers of the people on the missing person's historical travel route, such as the phone numbers of the surrounding neighbors, the phone numbers of the shop owners along the street, etc., and then obtain the phone numbers of the people on the determined search route , such as the mobile phone number of the gatekeeper and the bus station staff. A person set is composed of the first person on the historical travel route and the second person on the search route. Determine whether the personnel in the personnel set are within the coverage of the edge data center that processes the data, classify the personnel within the coverage of the edge data center that processes the data as the first target personnel, and classify the personnel that do not belong to the coverage of the edge data center that processes the data The insider is determined as the second target person, and the edge data center processing the data sends the missing person's appearance, gender, clothing, missing time, missing location and other information to the first target person through SMS and MMS. The edge data center that processes the data carries the assisted investigation information on the assisted investigation command and sends it to the edge data centers in other 5G network slice areas. The missing time, missing location and other information are sent to the second person.

The above step 104 also includes: using the target historical travel route and the missing person search route corresponding to the current search time period to form a route set; obtaining the response information of the first person and the second person corresponding to the current search time period to the missing person assistance information; Response information, in the route set, determine the first target route with the highest probability of the missing person; and send the missing person assisting search information to the person on the first target route again.

The historical travel route is determined, but each search time period corresponds to a different search route. Therefore, the historical travel route is combined with the search route corresponding to each search time period to obtain multiple routes to form a route set. The response information is the feedback information given by the first person and the second person after receiving the assisting investigation information. The feedback information can be, for example, a person who has seen the suspected missing person, or a person who has never seen the suspected missing person. Make statistics on the feedback information, if the feedback information on a certain route is relatively positive, for example, there are more people on a certain route reporting that they have seen people who are suspected of missing persons, then the route can be confirmed as the probability of missing persons The largest route, that is, the first target route, further sends assisted investigation information to more people on this route, so that the missing assisted investigation information can be received by more people who may have seen the missing person, which helps to find the missing person in time .

The above step 104 also includes: sorting the search time periods according to the time between the search time periods from first to last; if the first target route is determined within the first search time period among the search time periods, Then according to sorting in each search time period, determine the next search time period of the first search time period; The second target route is selected from the missing person search routes corresponding to the search time period, and the missing person assisting search information is sent to the person on the second target route at the current moment or within the next search time period.

After receiving the feedback information, the route of the missing person can be roughly determined. If the above-mentioned first target route is determined in the first search time period in each search time period, the first target route is determined in each search time period according to the ordering. The next search time period of the search time period can be understood as, if the feedback is received within the first hour, the approximate walking route A of the missing person is determined, and A is taken as the first target route. Determine that the next time period corresponding to the first hour is 2-3 hours, and the search radius corresponding to 2-3 hours is 100-300 kilometers, and the traffic transfer station within 100-300 range from the missing place is the destination. Get multiple routes. For example, route B from the place of disappearance to the bus station, or route C from the place of disappearance to the train station. Comparing the determined route A with multiple routes B and C, for example, if route A is in the same direction as route B, it can be determined that the route where the missing person is most likely to appear in the next time is route B, then route B The route can be used as the second target route, and then the assistance information can be sent to the personnel along the B route. Since the personnel along the B route have a higher probability of seeing the missing person in the next time, it is helpful to timely Find the missing person.
