Description

The system and method for preventing infectious diseases using small cells

The present invention relates to a system and method for preventing infectious diseases using small cells.

The recent global spread of COVID-19 is a global concern. As of June 30, 2020, the total number of confirmed cases worldwide has exceeded 10 million, surpassing the number of infected with H1N1 flu 11 years ago. The provisional fatality rate of COVID-19 is about 5%, which is about 25 times higher than the 0.2% fatality rate of the H1N1 influenza epidemic in 2009. It first occurred in Wuhan, Hubei Province, China on December 1, 2019, and began to spread outside China in earnest from January 2020, and rapidly spread to most countries on the planet except for some countries and regions and all continents except Antarctica by the end of March. became The World Health Organization (WHO) declared an international public health emergency on January 31, 2020, raised the global risk of COVID-19 to 'very high' on February 28, and the COVID-19 pandemic on March 11. to declare a pandemic. It is a very important issue to determine the period of explosive spread of this rapidly spreading fatal disease and whether it has reached a stable stage.

As for the movement route of the confirmed person infected with the disease recognized by the Korea Centers for Disease Control and Prevention, information on the place and time passed based on the statement of the confirmed person is unclear, and it is not possible to accurately determine whether the person has been in direct contact with the confirmed person or suspected person. Fear among people about infection is increasing.

Moreover, public opinion about human rights violations is increasing with respect to information provided by the Korea Centers for Disease Control and Prevention and local governments about the path and personal identity of confirmed patients. Along with the controversy over infringement, there is a conflict with the people's right to know in terms of their right to live.

In addition, due to the proximity or contact of a person with a confirmed disease, the burden on me, my family, co-workers, and the community is increasing, and damage is occurring due to exposure to the disease.

Although various patent technologies for infection prevention have been disclosed in the prior art, in the case of Patent Publication 10-2017-0021692, the inconvenience that an individual has to have a separate creation, registration, and transmission procedure, there is no response system for the nth infection, and , this inconvenience can lead to the same inconvenience as the current QR code access method or telephone method, and imperfection of quarantine. There is a problem that the invention itself does not work if the necessary application is not executed, and registered patent 10-2166627 uses LBS (Location-Based Technology) of the telecommunication company to identify the location information by time of the confirmed patient and track the suspected contact within a certain radius. However, in the case of the above registered patent, location tracking through GPS cannot be received (location tracking impossible) inside a building or underground, and the network method has poor accuracy (the range is too wide), and multiple methods are mixed. Although the above hybrid method has the effect of improving some of the shortcomings, there are still limitations, and considering the reality that more than 90% of the route of transmission and spread of infectious diseases is due to indoor infection, whether or not to enter a specific facility There is a problem that there is no specific technology for the part that can be judged and tracked.

Since the above-described small cell is merely a known technology, a more detailed description thereof will be omitted.

More specifically, as shown in FIG. 1 , the infectious disease prevention system 100 using a small cell according to an embodiment of the present invention includes a mobile communication terminal 10 , a small cell 20 and a quarantine agency server 50 . may include

Each of the components 10 , 20 , 30 , 40 and 50 is connected through a network. Here, the network refers to a connection structure in which information exchange is possible between each node, such as a plurality of terminals and servers. Examples of such networks include RF, 3rd Generation Partnership Project (3GPP) network, Long Term Evolution (LTE). Network, 5th Generation Partnership Project (5GPP) network, World Interoperability for Microwave Access (WIMAX) network, Internet, Local Area Network (LAN), Wireless Local Area Network (Wireless LAN), Wide Area Network (WAN), PAN (Personal Area Network), Bluetooth (Bluetooth) network, NFC network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. include, but are not limited thereto.

In the following, the term at least one is defined as a term including the singular and the plural, and even if the at least one term does not exist, each element may exist in the singular or plural, and may mean the singular or plural. it will be self-evident In addition, whether each component is provided in singular or plural may be changeable depending on the embodiment.

The mobile communication terminal 10 is connected to the wireless communication network of the small cell 20 installed in the collective facility, and provides terminal identification information.

The mobile communication terminal 10 provides pandemic infected person information and pandemic infection rules provided by the quarantine agency server 50 through the macrocell mobile communication network managed by three mobile communication companies, for example, SKT, KT, LGU+ communication company servers. , safety level (risk level) for confirmed infection and/or contact with suspected infection, multi-facility access certificate, self-isolation subject, vaccination, diagnosis, quarantine evasion, etc. It may be a terminal that receives a message including indication information.

In addition, the mobile communication terminal 10 is a wireless communication device that ensures portability and mobility, PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone ), a smart pad, a tablet PC, and the like, may include all kinds of handheld-based wireless communication devices.

Next, the small cell 20 is a device installed in an assembly facility to provide a wireless communication service to adjacent mobile communication terminals, and supports a small cell wireless network having a narrower coverage than a macro cell.

It can operate within the coverage of the macro cell 30 and provides a wireless communication service to mobile communication terminals connected to the small cell.

Here, the small cell 20 is a multi-group facility, for example, a femtocell, a picocell, depending on the size and characteristics of a facility where two or more people gather (shopping malls, residential buildings, public transportation means) and outdoor dense space multi-group facilities. (Picocell) and microcell (Microcell), etc. are mixed and installed.

Next, the macro cell 30 communicates with the small cell 20 .

On the other hand, the communication status of the macro cell 30 communicating with the small cell 20 installed in the multi-set facility is managed by each communication company server, and the communication company server monitors the state of the wireless communication service of the small cell, and If it is determined that the state of the wireless communication service is unstable, it is possible to control to attempt relaying with other small cell base stations nearby.

2, the quarantine agency server 50 uses the identification information of a plurality of mobile communication terminals collected from the small cell provided by the communication company server that manages the macro base station to track the location and movement of the mobile communication terminal, and a pen Users of mobile communication terminals overlapping the location movement and small cell coverage by time of a confirmed person with a pandemic infectious disease are classified as suspected of being infected with the confirmed person, and information on the movement of the classified suspect is provided.

That is, when a confirmed case occurs, the quarantine agency server 50 receives information on the movement route of the confirmed person for a certain period (eg, 14 days) from the date of confirmation from the server of the telecommunication company joined by the confirmed person, and the confirmed person from other telecommunication companies It receives information of contacts and suspected contacts who have movement information that matches or overlaps with the moved movement information, classifies the contact and suspected contact as suspected infection, and provides the classified movement information of the suspected infection.

In other words, the quarantine agency server 50 may simultaneously extract the first to the n-th contacts who have been in contact with the confirmed person.

In addition, the quarantine management server 50 is a mobile communication terminal located within the coverage of the small cell, such as whether the infected person has been in contact, proximity to contact, subject to self-quarantine, whether or not to vaccinate, whether to diagnose, whether to evade quarantine, etc. At least one level of safety (risk level) may be configured to transmit an authentication mark including classification information classified into a plurality of levels.

In addition, when a confirmed person occurs, the quarantine management server analyzes the location and movement of the confirmed person by time for a certain period (eg, 14 days) that is subtracted from the confirmation date of the confirmed person.

In addition, the quarantine management server 50 collects through a small cell in a place that overlaps with the location and movement lines of the confirmed patients by time for the predetermined period (eg - 14 days). The stored information is transmitted from each telecommunication company server, and the date and time at which the confirmed person is located in the assembly unit location, and the location and movement line moved within the assembly unit location are provided.

In addition, the quarantine management server 50 transmits a safety level certificate for authenticating whether or not the user is infected when the mobile communication terminal enters the multi-group facility.

In addition, the quarantine management server 50 analyzes the conversion ratio of the communication on/off state of the mobile communication terminal by region and facility for a certain period of time, and there is a statistically significant difference in the conversion rate of the communication on/off state in the nationwide unit. Transmits information on necessary quarantine measures for a facility or area in which it is located to on/off mobile communication terminals and quarantine-related organizations.

More specifically, the quarantine agency server 50 includes an information collection unit 51, a location path analysis unit 52, a safety level analysis unit 53, a quarantine rule guide sending unit 54, and a safety level certificate issuing unit ( 55) may be included.

The information collection unit 51 collects personal identification information and location information of the mobile communication terminal 10 communicating with the small cell built in each communication company server.

In addition, the information collection unit 51 may collect infectious disease confirmed patient information or diagnosis results from a medical institution server. In addition, it is possible to collect the information of the subject to be vaccinated and the vaccinated persons from the server of the medical institution.

Next, the location route analysis unit 52 analyzes the location movement information of the person confirmed with the infectious disease based on the location information that the person confirmed with the pandemic has moved for a certain period of time (eg, -14 days) from the date of confirmation.

In addition, the location route analysis unit 52 analyzes the location route of the communication subscriber of each telecommunication company having a movement line overlapping the location movement line of the infectious disease confirmed person based on the location movement information of the confirmed infectious disease person.

In this case, communication subscribers of each telecommunication company having a location path that matches or overlaps with the location path of the confirmed person is classified as a suspected infectious disease (eg, primary contact) in the quarantine target classification unit to be described later. In the same process, communication subscribers of each telecommunication company who have a location path that matches or overlaps with the location path of the primary contact is classified as a suspected infectious disease (e.g., a secondary contact) in the quarantine target classification unit to be described later. Analyze the location path of the nth contact through

Meanwhile, the location path analysis unit 52 estimates the contact distance between the mobile communication terminals based on the 1:1 signal exchange distance with the small cell at the same time and the same place.

The contact distance is provided to a safety level analysis unit to be described later to calculate the safety level of users classified by the quarantine target classification unit. The description of the above-described safety level calculation will be described in more detail in the description of the safety level analysis unit.

On the other hand, the location route analysis unit 52 derives the movement route and location information of the confirmed person by time through time-series analysis from the location information for each time period during the past certain period, referring to FIG. 9 . Furthermore, the location path analysis unit 52 determines the contact suspect and non-target through time series analysis and data mining of a plurality of mobile communication subscriber information searched within a certain radius in the same time zone as the movement route and location information for each time period of the infected person. Then, the information of the suspected contact is derived, and the contact time and contact location information from the derived information of the suspected contact is stored after improving the accuracy through deep learning. Therefore, the location path analysis unit 52 includes an algorithm for time-series analysis, an algorithm for determination for data mining, and an algorithm for performing deep learning.

In addition, the location path analysis unit 52 can analyze the location movement of the Nth infected person generated from the infected target based on the communication record information of the mobile communication terminal that exchanged signals with the small cell base station collected from each communication company server. .

For example, the location route analysis unit 52 can analyze by setting the location movement line of the infected contact (the N-th contact) who is negative among the infected contacts overlapping the location movement line of the confirmed infected person as the tracking range of the infected person ( see Fig. 10).

In addition, the location path analysis unit 52 may perform the inspection by tracing enlarged to the Nth order, and when a negative determination is made for a contact of a specific order, the tracking inspection may not be performed any more.

Next, the quarantine target classification unit 53 classifies the quarantine target based on the information collected by the information collection unit 51 and the location information analyzed by the location path analysis unit 52 .

The quarantine target is classified as an infection risk.

The confirmed case of the infectious disease is judged by the information of the inspector who is positively determined by the medical institution, the suspected infection is classified based on whether it overlaps with the location of the confirmed infected person, and the contact is classified based on the location and movement of the suspected infection. do.

Next, the safety analysis unit 54 determines the location movement line overlapping the location movement line of the confirmed patient who exchanged signals with the small cell in the same place for a certain range of time, the signal exchange distance with the small cell (contact proximity), and the user's Analyze the risk of suspected infections and contacts of infected people based on whether or not they are vaccinated.

The quarantine rule guide sending unit 54 provides quarantine rule information according to the user's safety level analyzed by the safety level analysis unit 54 .

For example, in the case of the infection or suspected contact, quarantine rule information including quarantine rule information at the time of self-quarantine, warning information on departure from the self-quarantine area, and information on an adjacent screening clinic is provided.

In addition, the quarantine rule guide sending unit 54 provides communication connection status to quarantine-related institutions and quarantine evasion suspects based on the communication connection status of the mobile communication terminals of a plurality of suspects (confirmed, suspected, and contacted) by region. It is possible to transmit necessary measures according to the suspicion of quarantine evasion due to the change of (ON.Off).

Next, the safety level certificate issuing unit 54 may be configured to issue a mobile safety level certificate to communication subscribers subscribed to each communication operator (see FIG. 6 ).

The mobile safety level certificate sets a level based on the safety level status for each user of the safety level analysis unit 54 .

The mobile safety level certificate is a certificate used when entering and exiting a multi-group facility, and may be a certificate for confirming the user's infection safety level in the multi-group facility.

The mobile safety level certificate is information that classifies the infection safety level of the terminal owner by color grade. For example, the color grade is classified into green, red, pink and yellow, green is safe, red is infection, and pink is Suspected infection or self-isolation required status, yellow may be information for identifying whether there are more than Nth contact from a confirmed person or use of multi-group facilities for the last 2 weeks. The above-described color grade information is only an example, and all methods for identifying or displaying an infection state may be applied, but the present invention is not limited thereto.

4 is a flowchart illustrating a method for preventing an infectious disease using a small cell according to an embodiment of the present invention.

As shown in FIG. 4 , in the method of preventing an infectious disease using a small cell ( S700 ) according to an embodiment of the present invention, first, a communication network of at least one or more small cells installed in a plurality of multi-set facilities for each communication company server is established ( S710 ). ), the location information of the terminal communicating with the at least one or more small cells is collected for each communication company server (S720).

Next, the quarantine agency server 50 identifies the location of the confirmed infection for a certain period of time (eg -14 days) from the confirmation of infection in small cell base units, and then identifies small cells within a certain period (eg -14 days ). A communication subscriber of each communication company that matches or overlaps with the location information of the cell base unit is classified as a suspected infection contact (S730).

More specifically, referring to FIG. 8, in the S730 process, when an infected person occurs, the location of the infected person for a certain period of time (eg -14 days) is recorded through the small cell unique identification code or IP address as a small cell base unit. After tracing with , it includes the process of extracting suspected contacts within a certain range of time and space in the small cell base unit for a confirmed case, and sequentially extracting the 2nd to Nth contact suspects for the suspected contact for a certain period of time.

After that, the identification mark that changes the safety level for the suspected contact or quarantine evasion suspect that matches or overlaps with the location movement of the confirmed infection through the respective telecommunication company servers from the quarantine agency server and information necessary for diagnosis, self-qualification notification, and quarantine is transmitted (S740).

The S740 process is a mobile safety step in which the quarantine rules and safety (risk) steps are recorded according to the infection risk, such as 1) diagnosis required, 2) self-isolation target, 3) multiple access facility restrictions or self-isolation notification for the extracted suspected contact. It may include the process of transmitting a certificate.

Thereafter, when the diagnosis result for the suspected contact is negative, or in the case of non-infection, such as the release of the self-isolation target, the process of changing and transmitting the corresponding mobile safety level certificate may be included.

In addition, the S740 process may include a process of not transmitting a danger warning message to a third party located in the facility and allowing access when the previously transmitted safety (danger) level is changed to a safety level when entering the multi-group facility.

In addition, in the case of an attempt to enter a multi-group facility, it may include a process of determining whether to allow access by safety (danger) stage and transmitting a danger warning message to a third party located in the facility when entering the facility.

That is, in the S740 process, a preset safety level authentication mark is transmitted to the infected person and the N-th contact of the confirmed infected person for a recent period of time among the quarantine targets possessing a mobile communication terminal, and the N It may include a process of transmitting a mobile safety level certificate including a safety level authentication mark to a contact whose diagnosis result is voiced among car contacts and a target for the contact.

In addition, it may include the step of transmitting a mobile safety level certificate including a risk level authentication mark to a person suspected of contact or a person suspected of infection or self-quarantine who has come in contact with a confirmed infection.

In addition, based on the communication connection status of the mobile communication terminals of a plurality of suspects (confirmed, suspected, and contacted) for each region, according to the change of communication connection status (ON. It may further include the step of transmitting necessary measures for the suspicion of avoidance of quarantine.

On the other hand, the infectious disease prevention method (S700) using a small cell according to an embodiment of the present invention determines the conversion ratio of the communication on/off state of the mobile communication terminal for each region, each base station, and each small cell within a certain period of time during the pandemic prevention period. In order to analyze and block quarantine evasion attempts, it is a process of guiding quarantine-related organizations and suspected quarantine evasion agencies with information on necessary quarantine measures for facilities or regions with statistically significant differences in the conversion rate of communication on/off state at the national level. may further include.

The route tracing target referred to in the present invention targets contacts for a certain period of time (eg -14) from the date the first confirmed patient is confirmed.

In addition, the target of the notification of quarantine rules and the change of the risk mark for each safety stage is when the last contact of the first confirmed patient receives a negative diagnosis result, or when the fact of non-infection is confirmed after self-quarantine for a certain period (eg +14 days) from the point of contact. (Example: Red → Green).

The same process is applied to the Nth contact.
