1 is a configuration diagram of a system for visiting roaming-based infectious disease visiting station according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating a network for detecting subscriber entry according to an embodiment of the present invention.

Referring to FIG. 1, the subscriber station 10 uses an outbound roaming service that accesses an overseas network (VLMN) 20 in order to use the Internet. Overseas network 20 authenticates subscribers by interworking with HSS (Home Subscriber Server) of home network (Home Public Land Mobile Network, HPLMN) 30, and roaming service and text guide (roaming guidance, etc.) by interworking with home network 30 ).

When the subscriber station 10 accesses, the overseas network 20 transmits the connected subscriber information and the corresponding country information (ie, visited country information) to the home network 30. Therefore, the home network 30 can know the subscriber information and the visited country information connected to the overseas network 20.

The subscriber information is information for identifying a subscriber. For example, the subscriber information may be subscriber terminal information such as an International Mobile Subscriber Identity (IMSI) or a Mobile Station Integrated Service Digital Network (MSISDN), but the overseas network 20 and the home network ( It may be determined in various ways according to the overseas roaming agreement in 30). The country information is information that can identify a country. For example, the country information may be a mobile country code (MMC) and a mobile network code (MMC), which are country-communicator code combinations. It can be determined variously according to the international roaming interworking agreement.

The overseas roaming-based infectious disease visiting station detection history detection system (hereinafter, simply referred to as a 'visit history detection system') 100 interworks with the home network 30, the subscriber passport management server 110, and the disease management server of the overseas visiting subscriber. (Simply referred to as a 'disease management server') 130, and an infectious disease onset visit notification device 150.

In addition, the visit history detection system 100 extracts the access information of the entry registration base station 200 and the subscriber terminal 10 to which the subscriber terminal 10 enters upon arrival and delivers it to the disease management server 130. Subscriber entry notification device 300 may further include.

The entry registration base station 200 is a base station installed so that a terminal possessed by an entrant accesses and registers a location in the home network 30. Through this, the entry base station 200 can confirm entry of a subscriber having an entrant terminal. The immigration registration base station 200 may be installed in a specific section of a moving line passing by an entrant at an airport or a port, and may be installed, for example, at a quarantine station, an immigration desk, a baggage claim area, or the like installed at an airport / port. The entry registration base station 200 may be installed in a space through which an entrant passes, and particularly, may be installed in a shielded space that blocks a signal of an external base station or reduces signal strength.

The entry registration base station 200 may be a macro base station or a femto base station. The entry registration base station 200 may be constructed with a tracking area (TA) different from the neighboring base stations. The entry registration base station 200 may have a stronger signal strength than the neighboring base stations. The subscriber entry notification device 300 may be referred to as a mobile edge cloud (MEC) server.

In the following, the visit history detection system 100 will be described in detail.

The subscriber passport management server 110 maps and manages subscriber information and passport information. The subscriber information may include a telephone number or terminal identification information. Passport information may include passport number, name, photo and the like. For example, the subscriber passport management server 110 may store terminal identification information such as MSISDN in correspondence with subscriber passport information, but subscriber information corresponding to passport information may vary in accordance with the linkage protocol with the disease management server 130. Can be decided. Meanwhile, passport information mapped to subscriber information may be stored in the disease management server 130.

The disease management server 130 manages infectious disease infecting station information.

The disease management server 130 receives subscriber information and visited country information of terminals connected to the overseas network from the overseas roaming service control device of the home network 30. Through this, the disease management server 130 manages the overseas visit history for each subscriber. The overseas roaming service control device may be, for example, a Roaming Service Control Point (RSCP) that controls voice use and text transmission or a Network Service Control Point (NSCP) that controls data use. It can be changed in various ways according to the network design. The disease management server 130 will be described in detail with reference to FIG. 3 in a manner of receiving subscriber information and visited country information connected to an overseas network from an overseas roaming service control device of the home network 30.

The disease management server 130 receives a subscriber entry notification from the subscriber entry notification device 300 including the subscriber information that has entered the country from abroad. Then, the disease management server 130 extracts the visited country information of the subscriber included in the subscriber entry notification from the subscriber's overseas visit history. The disease management server 130 compares the extracted visited country information with the infectious disease infecting country information, and determines whether the subscriber visited the infectious disease developing country. The disease management server 130 transmits the determination result to the infectious disease disease station visit notification device 150. The determination result may include information such as visit to the infectious disease infectious country, non-visit, no information in the disease management server. If the overseas roaming service is not used, it may be determined that there is no information in the disease management server.

The disease management server 130 may transmit only the subscriber information visiting the infectious disease infecting country to the visit notification device 150, or may transmit all subscribers whether the infectious disease developing country visits to the visit notification device 150. At this time, the disease management server 130 may acquire the passport information of the subscriber in conjunction with the subscriber passport management server 110, and may transmit the presence or absence of the visit to the infectious disease infectious country visit notification device 150 for each passport information.

The infectious disease endemic station visit notification device 150 outputs notification information for confirming an entry person who visited the infectious disease endemic station on the basis of passport information at a quarantine station, an immigration desk or an airport / port. The administrator may check in real time the notification information of the entrant output on the screen of the infectious disease infectious country visit notification device 150, and determine in real time whether the relevant resident visited the infectious disease generating country. The notification information may include any one of an infectious disease visiting country, non-visiting, no information in the disease management server, and may display an image extracted based on the passport number on the screen to increase an alarm effect.

The infectious disease infectious country visit notification device 150 knows whether the infectious disease infectious country visits according to passport information from the disease management server 130, and thus, the infectious disease infecting country visitor through the passport number of the entrant who passes the immigration examination or the face recognition of the entrant. You can check. The infectious disease infectious station visit notification device 150 may display the presence or absence of the infectious disease infectious country visit at the time of immigration check in conjunction with the computing device of the immigration screening unit, and the infectious disease infecting station of the immigrant immediately after passing through the quarantine station in conjunction with the computing device of the quarantine unit. The presence or absence of a visit can be displayed, and in conjunction with the mobile device of the quarantine staff, the visitor can display the presence or absence of an infectious disease-infected country.

As such, the disease management server 130 may determine whether the subscriber visits the infectious disease-infected country in real time when the subscriber enters the immigration registration base station 200 to which the subscriber terminal 10 enters, and the subscriber terminal ( It is possible by the subscriber entry notification device 300 to extract the access information of the 10) and deliver it to the disease management server (130).

1 and 2, at least one entry registration base station 200 is installed at a specific location that can be connected to the terminal 10 of the entrant within the airport / port, for example, around the quarantine station (coverage is (Including quarantine).

Referring to FIG. 2A, the entry registration base station 200 transmits the access information of the terminal 10 to the mobile management entity (MME) 31 of the home network 30. At this time, the subscriber entry notification device 300 is located between the entry registration base station 200 and the MME 31, detects the signaling message transmitted from the entry registration base station 200 to the MME 31, and the subscriber information from the signaling message Can be extracted. Here, the subscriber entry notification device 300 may be designed in various locations according to a method for detecting a signaling message transmitted from the entry registration base station 200 to the MME 31.

The subscriber entry notification device 300 transmits the subscriber entry notification including the subscriber information entered into the country from abroad to the disease management server 130, and queries the visited country of the entrant. The subscriber entry notification device 300 may transmit a signaling message including subscriber information to the disease management server 130. The subscriber entry notification device 300 may obtain a signaling message transmitted from the entry registration base station 200 to the MME 31 in a deep packet inspection (DPI) manner. The signaling message is a message for confirming subscriber information connected to the entry registration base station 200. For example, the signaling message may be an initial attach message or a TA update request message. The subscriber entry notification device 300 separately configured for the entry notification may detect the subscriber entry on a standard basis and notify the disease management server 130 without modification of the communication protocol between the base station and the MME.

On the other hand, the entry registration base station 200 is assigned a tracking area (TA) that does not overlap with the surrounding base station. The entry registration base station 200 may be installed inside a quarantine station that can shield signals from neighboring base stations.

Assuming that the entry registration base station 200 is installed in the vicinity of the quarantine (which may be inside the quarantine, in the case of a shielded quarantine), subscriber entry may be detected as follows.

First, when a subscriber turns on the subscriber station 10 in the vicinity of the quarantine station, the subscriber station 10 first accesses an immigration registration base station 200 installed near the quarantine station. In this case, the entry registration base station 200 transmits the first access message to the MME 31, and the subscriber entry notification device 300 intercepts the first access message transmitted from the entry registration base station 200 to the MME 31 in the middle. Can be obtained.

Meanwhile, the subscriber station 10 may be turned on before the subscriber passes the quarantine band. In this case, in the LTE network, each base station is assigned a unique Tracking Area Identifier (TAI) value, and binds a plurality of base stations to form a tracking area (TA). The terminal performs a handover between base stations belonging to the TA list, and, when accessing the base station outside the TA list, transmits a TA update request message, which is a location registration message, to the MME 31 to receive a new TA list.

Accordingly, when the subscriber station 10 is turned on before the subscriber passes the quarantine station, the subscriber station 10 receives the TA list, and thus, when the subscriber station 10 accesses the entry registration base station 200, the subscriber station 10 receives the TA update message. The MME 31 must know that the subscriber station 10 is connected to the entry registration base station 200 in the MME 31 to force the transmission. For this purpose, the tracking area of the entry registration base station 200 is allocated so as not to overlap with the surrounding base stations. The entry registration base station 200 may be set stronger than the neighboring base station signal or may be installed inside the search station that may shield the signal of the neighboring base station. The shielded space may be implemented as a gate passage through which an entrant passes, as shown in FIG. When the entrant enters the shielded space, the entry registration base station 200 is installed inside the shielded space (for example, the ceiling), and signals of the base stations installed outside the shielded space may be blocked or signal strength may be weakly reached.

Specifically, when the tracking area of the entry registration base station 200 is allocated so as not to overlap with the surrounding base station, the subscriber station 10 enters the coverage of the vicinity of the search station or the entry registration base station 200, the first received TA list In step 2, the TA update request message is transmitted to the MME 31 to access the entry registration base station 200. Through such a mandatory TA update procedure, the subscriber entry notification device 300 may intermittently obtain a TA update request message transmitted from the entry registration base station 200 to the MME 31.

Referring to FIG. 3, the subscriber station 10 accesses an overseas network base station 21 of an overseas network (VPLMN) 20 in order to use the Internet or the like abroad. The overseas network base station 21 transmits the access information of the subscriber station 10 to the overseas network MME 22. The overseas network MME 22 interworks with a home subscriber server (HSS) 33 via a gateway location register (GLR) 32 of the home network 30 for subscriber authentication. The overseas network 20 is linked to the roaming service controller (RSCP) 34 and the network service controller (NSCP) 35, which is a roaming service control device of the home network 30, to the subscriber station 10, such as various prepaid roaming services. Provides texting services such as service and roaming guidance. When the roaming announcement message determined by the roaming service controller (RSCP) 34 is a short message service (SMS) message, the SMS message is transmitted by the short message service center (SMSC) 36 to the subscriber station 10.

After the signaling processing of the overseas network 20 and the home network 30, the data of the subscriber station 10 is transmitted to the overseas network base station 21, the overseas network S-GW (Serving Gateway) 23, and the home network P-GW (Packet). and a packet data network such as the Internet via a data network gateway (37).

As such, the roaming service controller (RSCP) 34 and the network service controller (NSCP) 35 of the home network 30 are connected to the overseas network 20 to the subscriber station 10 connected to the overseas network 20. Provide roaming services. In order to provide such a roaming service, at least one of the roaming service controller (RSCP) 34 and the network service controller (NSCP) 35 is connected to the subscriber information (for example, IMSI, MSISDN, etc.) receiving the roaming service; Visiting country information (MCC, MNC) is received from the foreign network 20. Therefore, at least one of the roaming service controller (RSCP) 34 and the network service controller (NSCP) 35 can know the country information visited by the subscriber, so that the subscriber information and the visited country information are transmitted to the disease management server 130. do.

The disease management server 130 receives the subscriber information and the visited country information received from the roaming service controller (RSCP) 34 or the network service controller (NSCP) 35 of the home network 30, and receives foreign visited country information for each subscriber. Manage by overseas visit history.

Referring to FIG. 4, the disease management server 130 operated by at least one processor may include an overseas visit history management unit 131 for each subscriber, an infectious disease developing station information management unit 133, and an visiting subscriber infecting disease infecting station visit confirmation unit ( 135, and a notification unit 137.

The overseas visit history management unit 131 for each subscriber receives the subscriber information and the visited country information received from the roaming service controller (RSCP) 34 or the network service controller (NSCP) 35 of the home network 30, Manage visited country information with overseas visit history.

The infectious disease infecting station information management unit 133 manages the infectious disease developing station information.

The infectious disease infectious country visit confirmation unit 135 of the entry subscriber receives the entered subscriber information from the subscriber entry notification device 300. The infectious disease infectious country visit confirmation unit 135 of the entry subscriber searches for the overseas visit history corresponding to the entered subscriber information in the overseas visit history management unit 131 for each subscriber to determine whether the subscriber visits the infectious disease infecting country.

The notification unit 137 works with the subscriber passport management server 110 to obtain passport information corresponding to the subscriber information. Alternatively, the notification unit 137 may store passport information corresponding to the subscriber information. The notification unit 137 transmits the presence or absence of the visit of the infectious disease infectious country to the infectious disease infectious country visit notification device 150 together with the passport information of the subscriber.

On the other hand, when the subscriber station 10 is turned on to the coverage of the entry registration base station 200, the subscriber station 10 accesses the entry registration base station 200 and transmits the initial access message or TA update request message The disease management server 130 may transmit the infectious disease infectious country visit information of the entrant from the subscriber entry notification device 300 to the infectious disease infectious country visit notification device 150. However, when the power of the subscriber station 10 is turned off in the coverage of the entry registration base station 200, the subscriber entry notification device 300 cannot confirm the entry of the subscriber station (10). Therefore, the disease management server 130 or a separate device periodically monitors whether the subscriber who has overseas visit history accesses the home network 30. If it is determined that the subscriber has entered the country, the disease management server 130 or the separate device may check whether the subscriber visits the infectious disease infectious country, and transmit the subscriber information visiting the infectious disease infectious country to a designated notification device (not shown). .

Referring to FIG. 5, the subscriber station 10 accesses the overseas network 20 in order to use the Internet in a foreign country (S110). The HSS 33 of the home network 30 authenticates the subscriber station 10 in association with the overseas network 20.

The home network 30 provides a roaming service to the subscriber station 10 in cooperation with the overseas network 20 (S120). At this time, the overseas roaming service control device of the home network 30, in order to provide a roaming service to the subscriber terminal 10, subscriber information of the subscriber terminal 10 from the foreign network 20 (for example, IMSI, MSISDN, etc.) And country of visit information (MCC, MNC). The overseas roaming service control device may be, for example, a roaming service controller (RSCP) 34 or a network service controller (NSCP) 35.

The overseas roaming

service control apparatus

34 or 35 transmits the subscriber information and the visited country information of the subscriber terminal 10 provided with the roaming service to the disease management server 130 (S130).

The disease management server 130 receives the subscriber information and the visited country information from the overseas roaming

service control apparatuses

34 and 35, and manages the overseas visited country information for each subscriber as an overseas visit history (S140).

Referring to FIG. 6, the subscriber entry notification device 300 obtains a message transmitted from the entry registration base station 200 to the MME 31 (S210). The message may be an initial access message or a TA update request message of the subscriber station 10. When the subscriber station 10 powered on enters the coverage of the entry registration base station 200, the entry registration base station 200 may be connected to the entry registration base station 200 to register the location of the subscriber station 10. The installation location, TA assignment different from the neighbor base station, and signal strength stronger than the neighbor base station are considered.

The subscriber entry notification device 300 extracts the subscriber information entered from the acquired message (S220). The subscriber information may be IMSI, MSISDN, or the like, which is a form of subscriber information managed by the disease management server 130.
