Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This is a national stage application of PCT/KR2018/009545 filed on Aug. 20, 2018 which claims priority from Korean Patent Application No. 10-2017-0111407 filed on Aug. 31, 2017, in the Korean Intellectual Property Office, the disclosures of which are hereby incorporated herein in their entirety by reference. 
    
    
     BACKGROUND 
     1. Field 
     The present disclosure relates to preventing the spread of infectious diseases, and more particularly, to an infectious disease proliferation prevention system and method for preventing infectious diseases in some areas from spreading across the world using wireless communication information of mobile terminals possessed by global communication companies in the world. 
     2. Related Art 
     The global challenge is the fast spread of endemic infectious diseases (hereinafter, infectious diseases), for example, Ebola, Middle East respiratory syndrome (MERS) and Zika virus diseases. In 2015, the Republic of Korea had the MERS national disaster. Prior to that, in 2014, there were about 11,000 deaths around the world since the Ebola outbreak. In 2016, Zika viruses have spread to 29 countries in two months, causing losses of about 64 billion dollars in the tourism industry. Additionally, it is foreseen that at least one infectious disease will sweep across the world within 100 years in the future and the probability that at least four infectious diseases will occur is 20% or higher. Additionally, it is foreseen that global average economic losses of 60 billion dollars or more per year will occur due to potential infectious diseases. 
     Meanwhile, infectious diseases in some areas tend to spread across the world rapidly and widely. The reason is as follows: the advent of many low-cost airlines makes it easy to move from place to place all over the world. Additionally, due to income rises, changes in attitude towards life, and emergence of the concept of YOLO or you only live once, the number of people who move abroad for the purpose of trip and business is increasing at a fast pace. In particular, Africa, India and South America were least-visited countries, but as there is an increase in the number of travelers to these areas, fatal infectious diseases in there are more likely to spread across the world. 
     If it fails to prevent infection in infectious disease-affected areas, infectious diseases will spread all over the world, causing tremendous damage. In 2015, MERS was introduced to the Republic of Korea by a patient returning from Saudi Arabia, and then, the patient was not screened at the airport, and after symptoms developed, the first visited hospital failed to prevent infection. As a result, since the MERS outbreak, epidemiology and prevention efforts have been devoted so much, but nevertheless tremendous damage occurred. To prevent the spread of infectious diseases, global efforts are required to manage the infectious diseases. 
     As part of these efforts, most countries force, by law, people returning from infectious disease-affected areas to report their visit to the infectious disease-affected areas. However, to report the visit to infectious disease-affected areas, visitors should know information about the types of the infectious diseases and the infectious disease-affected areas. However, there are many types of infectious diseases, and the infectious disease-affected areas may change over time, so it is difficult to create environments in which visitors can make voluntary reports. Additionally, in case that reporting is not mandatory and is done voluntarily as a personal duty, if damage occurs afterwards, that will be so much. 
     Accordingly, there is a need for global efforts to accurately detect people who have visited infectious disease-affected areas, and provide them with testing services related to the corresponding infectious diseases.

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT 
     The foregoing objects, features, and advantages will become apparent from the following detailed description with reference to the accompanying drawings, and accordingly, those skilled in the art will be able to easily practice the technical aspects of the present disclosure. Furthermore, in the description of the present disclosure, when it is deemed that a certain detailed description of known technology related to the present disclosure may unnecessarily render the key subject matter of the present disclosure ambiguous, the detailed description is omitted herein. Hereinafter, an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. 
     It is possible to monitor travelers&#39; visits to specific countries using airport entry and exit information. Additionally, it is possible to identify travelers&#39; visits to infectious disease-affected countries and areas using credit card payment information from financial companies and reservation information from travel agencies/insurance companies/airlines. It is possible to identify countries and areas information that travelers visited through credit card payment information from credit card companies or bank exchange information in foreign countries. Additionally, it is possible to identify foreign countries and areas that travelers visited using flight and hotel booking information from travel agencies and traveler insurance information. However, in the case of credit cards, it is possible to identify travelers&#39; visits to infectious disease-affected countries only when the travelers use their credit cards in the corresponding countries. It is difficult to manage even lots of medium- and small-sized travel agencies. 
     Many mobile communication subscribers use international roaming services when visiting foreign countries. Some mobile communication subscribers buy and use Subscriber Identity Module (SIM) cards in foreign countries that they visited. Mobile communication companies can detect countries that their subscribers visited while international roaming, but cannot know the detailed information about cities or areas in the corresponding countries. Additionally, when their subscribers buy and use SIM cards in foreign counties, the mobile communication companies cannot even know the countries that the subscribers visited. Meanwhile, no matter whether mobile communication subscribers use international roaming or local SIM cards, the subscribers&#39; mobile terminals use wireless communication services (for example, voice call, video call, text message transmission/reception, wireless Internet) via base stations covering the areas in which the subscribers are currently located. Accordingly, local mobile communication companies that manage the corresponding base stations can detect area information where the mobile terminals are located. Accordingly, cooperation between mobile communication companies in the world makes it possible to detect countries and even areas that mobile communication subscribers visited using wireless communication information of mobile terminals. An embodiment of the present disclosure detects countries that mobile communication subscribers visited and the period of stay using wireless communication information of mobile communication systems. Using the wireless communication information, it is possible to detect countries and areas subscribers visited and the period of stay. When infectious disease outbreak information is applied to it, it is possible to analyze visits to infectious disease-affected countries or areas and infectious disease risks for each person. 
       FIG. 1  is a diagram showing a communication environment of an infectious disease proliferation prevention system according to an embodiment. Referring to  FIG. 1 , the infectious disease proliferation prevention system  10  forms an alliance with a plurality of mobile communication companies in the world to communicate with mobile communication systems  20 : 1 ,  2 ,  3 , . . . , N of the plurality of mobile communication companies. The infectious disease proliferation prevention system  10  stores and manages infectious disease information occurred in the world, and continuously manages infectious disease-affected area visitors extracted based on wireless communication information collected by the mobile communication systems  20  of the plurality of mobile communication companies, to prevent the spread of the infectious diseases across the world. 
     The mobile communication system  20  provides a wireless communication service to a mobile terminal  30  subscribed to the corresponding company, a mobile terminal  30  allowed to roam abroad, or a mobile terminal  30  of a foreign traveler who buys and uses a SIM card in a country that the traveler visited. The mobile communication system  20  may extract information of a mobile terminal  30  having actually visited the infectious disease-affected area by matching the infectious disease information received from the infectious disease proliferation prevention system  10  and a list of mobile terminals suspected to visit infectious disease-affected areas, with the wireless communication information of the mobile terminal  30 , and transmit the extracted information of the mobile terminal  30  to the infectious disease proliferation prevention system  10 . To provide the wireless communication service to the mobile terminal  30 , the mobile communication system  20  periodically detects location information of the mobile terminals  30 , and automatically collects the wireless communication information of the mobile terminal  30  when the mobile terminal  30  is powered on. Here, the wireless communication information may include area information (location information of the mobile terminal) that the user of the mobile terminal  30  visited, the first visit date and the last departure date, and identification information (for example, International Mobile Equipment Identity (IMEI), International Mobile Subscriber Identity (IMSI), Mobile Subscriber Integrated Service Digital Network (MSISDN)) of the mobile terminal. 
     When the mobile terminal  30  subscribed to the corresponding company go abroad and use an international roaming service, the mobile communication system  20  may collect roaming data of the corresponding mobile terminal  30 . For example, when the mobile terminal  30  performs location registration in the foreign visited network (for example, power on when arriving at the country that the mobile terminal  30  visited), the mobile communication system  20  may collect the roaming data of the mobile terminal  30 . The roaming data is information of the visited network, and includes communication company information of the visited network and country information. For example, when the user of the mobile terminal  30  takes a trip to Kenya, Africa and uses an international roaming service, the mobile communication system  20  of the home network to which the mobile terminal  30  has subscribed, for example, Republic of Korea KT, may detect that the visited network that the user of the mobile terminal  30  visited is in Kenya using roaming data. The mobile communication system  20  of the home network cannot collect information about an area that the user of the corresponding mobile terminal  30  visited in Kenya. In contrast, the mobile communication system  20  of the visited network that provides the wireless communication service in Kenya, for example, Safaricom, may collect information (visited area information) about an area that the user of the corresponding mobile terminal  30  visited near a popular restaurant in Nairobi (capital), Kenya, while providing the wireless communication service to the corresponding the mobile terminal  30 . Additionally, the mobile communication system  20  of the home network may analyze countries that the mobile terminal  30  visited through analysis of transmitted/received text message records, or voice or video call records of the mobile terminal  30  in the foreign visited network. 
     The infectious disease proliferation prevention system  10  may provide an infectious disease proliferation prevention service using the wireless communication information of the mobile terminal  30  possessed by the plurality of mobile communication systems  20  without directly collecting the wireless communication information of the mobile terminal  30 . In an embodiment, the mobile communication system  20  may refer to a single network equipment or a set of network equipment that provides a mobile communication service, and performs an operation for infectious disease proliferation prevention by collecting wireless communication information for infectious disease proliferation prevention and communicating with the infectious disease proliferation prevention system  10 . 
     The mobile terminal  30  is a mobile communication terminal, and is a device that can use message services, call services or wireless Internet services by accessing the mobile communication system  20 . When the mobile terminal  30  moves from the home network to the visited network or from the visited network to the home network, the mobile terminal  30  may perform location registration, and the mobile communication system  20  may detect the country at which the mobile terminal  30  is currently located using location information at the time of location registration. The mobile terminal  30  may be used interchangeably with a User Equipment (UE), a Mobile Station (MS), a User Terminal (UT), a Subscriber Station (SS), or the like. 
     A database  40  may store information necessary to provide the infectious disease proliferation prevention service, and provide information requested from the infectious disease proliferation prevention system  10 . According to an embodiment, the database  40  may store a list of mobile communication systems  20 : 1 ,  2 ,  3 , . . . , N by country, infectious disease information occurred in the world updated in real time, and a list of mobile terminals  30  having visited affected areas.

FIG. 6  is a diagram showing the affected area visitor terminal information transmitted to the infectious disease proliferation prevention system  10  by each mobile communication system  20  according to an embodiment. 
     The affected area visitor managing unit  14  may classify the affected area visitor terminal information received from the plurality of mobile communication systems  20  by infectious disease, generate an affected area visitor terminal list by infectious disease and store the affected area visitor terminal lists in the database  40 .  FIG. 7  is a diagram showing a list of all affected area visitor terminals prepared by the infectious disease proliferation prevention system after collecting affected area visitor terminal information received from a plurality of mobile communication systems according to an embodiment. Referring to  FIGS. 6 and 7 , the affected area visitor managing unit  14  may collect the affected area visitor terminal information as shown in  FIG. 6  transmitted to the communication system interconnect unit  13  by the mobile communication systems  1 ,  2 , N, and generate the affected area visitor terminal list by infectious disease as shown in  FIG. 7 . Here, the affected area visitor terminal list may include the items of identification information (for example, IMEI) of the affected area visitor terminal, the name of the infectious disease, the first visit date, the last visit date and the number of days left until the incubation period expires. 
     According to an embodiment, the affected area visitor managing unit  14  may manage infectious disease-affected area visitors through the affected area visitor terminal list by adding, updating and deleting the affected area visitor terminal information received from the plurality of mobile communication systems  20  in a predetermined cycle. 
     When the affected area visitor terminal is transmitted for the first time and thus there is no record stored in the database  40 , the affected area visitor managing unit  14  may add and store the corresponding affected area visitor terminal information to the affected area visitor terminal list. In this instance, when the affected area visitor terminal is added to the affected area visitor terminal list for the first time, the infectious disease informing unit  12  may transmit the fact that the affected area visitor terminal entered the affected area to the affected area visitor terminal. The infectious disease informing unit  12  may transmit an infectious disease related message about the name of the infectious disease occurred in the affected area, symptoms of the corresponding infectious disease and actions to be taken when symptoms develop, to the affected area visitor terminal in the form of an SMS message, an MMS message or a Push message of smartphone Application. 
     When there is a record of the affected area visitor terminal stored in the database  40 , first, the affected area visitor managing unit  14  may identify if the infectious disease name is the same, and when the infectious disease name is the same, may update the affected area visitor terminal list by changing the last visit date to the recently received date, and re-calculating the number of days left until the incubation period expires. In this instance, the infectious disease informing unit  12  may transmit information about the corresponding infectious disease to the affected area visitor terminal in the form of an SMS message or an MMS message within the incubation period. When the infectious disease name is different for the same affected area visitor terminal, the affected area visitor managing unit  14  may determine the exposure to a new infectious disease, generate data together with the name of the infectious disease, and add the data to the affected area visitor terminal list for the corresponding infectious disease. 
     The affected area visitor managing unit  14  may update the affected area visitor terminal list in the predetermined cycle, and when the affected area visitor terminal list is updated, may calculate affected area visitor terminal information in which the incubation period is determined to expire and delete the affected area visitor terminal information from the affected area visitor terminal list. 
       FIG. 7  shows the calculation of affected area visitor terminal information in which the incubation period is determined to expire by the affected area visitor managing unit  14  under the assumption that the current date is Mar. 2, 2017. For example, referring to  FIG. 7 , in the case of the mobile terminal  17 , when a result (for example, Feb. 24, 2017) of adding the last visit date (for example, Feb. 10, 2017) to the incubation period (14 days) in the recently updated affected area visitor terminal list is earlier than the current date (Mar. 2, 2017), the affected area visitor managing unit  14  may determine that the incubation period expired (the number of days left until the incubation period expires=0), and delete the mobile terminal  17  from the affected area visitor terminal list. When the affected area visitor terminal is deleted from the affected area visitor terminal list, the infectious disease informing unit  12  may inform the expiration of the incubation period to the affected area visitor terminal in the form of an SMS message or an MMS message.

     In S 87 , the infectious disease proliferation prevention system  10  may manage the affected area visitor terminal list by adding, updating and deleting the affected area visitor terminal information transmitted from the plurality of mobile communication systems  20  in the predetermined cycle. When the affected area visitor terminal is transmitted for the first time and thus there is no record stored in the database  40 , the infectious disease proliferation prevention system  10  may add and store the corresponding the affected area visitor terminal information to the affected area visitor terminal list. In this instance, when the affected area visitor terminal is added to the affected area visitor terminal list for the first time, the infectious disease proliferation prevention system  10  may transmit the fact that the affected area visitor terminal entered the affected area to the affected area visitor terminal. According to an embodiment, the infectious disease proliferation prevention system  10  may transmit an infectious disease related message about the name of the infectious disease occurred in the affected area, symptoms of the corresponding infectious disease and actions to be taken when symptoms develop to the affected area visitor terminal in the form of an SMS message or an MMS message. Additionally, when there is a record of the affected area visitor terminal stored in the database  40 , first, the infectious disease proliferation prevention system  10  may identify if the infectious disease name is the same, and when the infectious disease name is the same, may update the affected area visitor terminal list by changing the last visit date to the recently received date and re-calculating the number of days left until the incubation period expires. In this instance, the infectious disease proliferation prevention system  10  may transmit information about the corresponding infectious disease to the affected area visitor terminal in the form of an SMS message or an MMS message within the incubation period. When the infectious disease name is different for the same affected area visitor terminal, the infectious disease proliferation prevention system  10  may determine the exposure to a new infectious disease, generate data together with the name of the infectious disease and add the data to the affected area visitor terminal list for the corresponding infectious disease. Additionally, the infectious disease proliferation prevention system  10  may update the affected area visitor terminal list in the predetermined cycle, and when the affected area visitor terminal list is updated, may calculate affected area visitor terminal information in which the incubation period is determined to expire and delete the affected area visitor terminal information from the affected area visitor terminal list. For example,  FIG. 7  shows calculation of affected area visitor terminal information in which the incubation period is determined to expire by the infectious disease proliferation prevention system  10  under the assumption that the current date is Mar. 2, 2017. In the case of the mobile terminal  17  of  FIG. 7 , when a result (for example, Feb. 24, 2017) of adding the final visit date (for example, Feb. 10, 2017) to the incubation period (14 days) in the recently updated affected area visitor terminal list is earlier than the current date (Mar. 2, 2017), the infectious disease proliferation prevention system  10  may determine that the incubation period expired (the number days left until the incubation period expires=0), and delete the mobile terminal  17  from the affected area visitor terminal list.
