[System for Collecting Visitor Information and the Method thereof for UPIS}

The present invention relates to a method for collecting user entry/exit information for a specific area or specific facility in an urban space, and an information collection system using the same. In more detail, an information collection system that collects use information of urban planning facilities, etc., determines a specific area to the information consumer according to the needs of the information consumer who wants to grasp the user's entry/exit information within the urban space. It is a method of receiving the location history information of the user terminal from the mobile communication company's location information providing server and collecting the entry and exit information of the users for the specific area, such as city parks, plazas, terminals, green areas, sports facilities, etc. In addition to collecting urban planning facility usage information that can be reflected in the establishment of urban planning by measuring the actual use of urban planning facilities, as well as establishing a quarantine zone according to the outbreak of infectious diseases such as COVID-19, The present invention relates to a method and system that enables users to quickly and accurately grasp the status of user access to any facility or area where an infected person has visited or an area requiring special quarantine measures.

The importance of information technology is increasing day by day in the establishment and management of urban planning. Recently, the concept of the Urban Planning Information System (UPIS) has been introduced, and information related to urban planning is systematically managed. It is effectively used for establishment and management. The Urban Planning Information System (UPIS) is a system that supports urban planning decisions by administrative agencies while computerizing urban planning information close to the people's property rights and providing them to the public. To explain in more detail, rational urban planning decisions can be made by providing relevant information by linking and establishing drawing information on areas, districts, zones, etc., and attribute information on cadastral, architecture, and environment in the urban planning space. It refers to the information management system supported. Therefore, the Urban Planning Information Management System (UPIS) builds a database of public announcements or announcements, decision records, figures, images, etc. It is utilized and supports various decisions related to urban planning.

In addition, in cities, infrastructure must be reflected as a physical element necessary for the maintenance of urban residents' life or urban functions. Among these infrastructures, there are urban planning facilities that must be determined by urban planning. Transportation facilities such as ports, airports, parking lots, tracks, and canals, space facilities such as plazas, parks, green areas, amusement parks, and public areas, as well as schools, playgrounds, public buildings, cultural facilities, sports facilities, libraries, research facilities, youth training There are also public/cultural sports facilities such as facilities. These urban planning facilities are facilities that need to be installed, expanded, and managed at an appropriate scale according to the growth or change of the city's population and size, and the lifestyle of urban residents is also dependent on changes in the city, social development, and economic conditions. As it is constantly changing, the usage pattern for urban planning facilities is also constantly changing. Therefore, when establishing and revising urban planning, urban planning that can properly perform urban functions will be possible only when appropriately reflecting these changes. Therefore, the urban planning information management system (UPIS) needs to include the use status of urban planning facilities, and development of an information system that can systematically measure the use of urban facilities and reflect them in urban planning is required.

Meanwhile, due to the impact of COVID-19 (COVID-19), which originated in China at the end of 2019 and spread around the world at a terrifying rate, there have been many changes across society, including human lifestyle. In the digital society, non-face-to-face work, represented by telecommuting and video conferencing, has rapidly shifted to an un-tact consumption culture that favors non-face-to-face consumption. We are going to face-to-face society. In addition to this, the concept of social distancing has been established. In addition, in the event of a confirmed case of an infectious disease, in order to prevent further spread within the city, it is necessary to isolate the area or facility and take quarantine measures, control access to the facility and area, or quickly and accurately identify the person entering the area. As necessary, methods and systems for digitally solving this have been developed and applied.

As a conventional system for this, there is a technology to find people who have visited or visited a specific area using base station information of a mobile phone network, but since it is only searched by information connected to the base station, it can quickly and accurately search for visitors by facility unit or by arbitrary area unit. There has been a problem that it is impossible to find. As an alternative to this, the location of the mobile phone terminal is identified using a triangulation method using the time difference of arrival (TDOA) exchanged with the base stations, and then it is determined whether the mobile phone terminal is located within a specific area or facility. However, it is difficult to make accurate judgments due to the problem of positioning errors and shaded areas inside buildings or underground facilities, and accurate measurement is difficult unless fingerprint data for the entire facility or area are accumulated. There is. In addition, the use of GPS can also be considered, but there has been a problem in that the effectiveness of the GPS is not operated, or an error occurs in an area where GPS signals cannot be received or in a shaded area.

Another object of the present invention is to provide urban information necessary for the use of urban planning facilities and demand forecasting to the urban planning information management system (UPIS) by allowing the use of specific areas or specific facilities to be accurately measured. The purpose of this is to provide timely information necessary for the establishment, change and management of urban planning.

Another object of the present invention is that even if a building or an underground facility exists in a specific area and it is impossible or difficult to measure the current location of user terminals existing in a specific area, whether or not it has entered the specific area The purpose of this is to provide a method to accurately determine whether or not it has advanced to and to provide a system for providing information on using urban planning facilities.

Another object of the present invention is a method capable of accurately determining whether users have entered or not entered a specific area arbitrarily determined according to the needs of an information consumer, rather than determining access to a predetermined area or a fixed facility.

In addition, in addition to the above-described features, in the second step, when the location information providing server is requested to provide the location history information, one of the base stations included in the HLR information during the predetermined time period is selected as a home location. When a user terminal to be determined is generated, it is specified as the terminal to be determined, and for the terminal to be determined, movement information including location information and measurement time while the home location is maintained is collected and converted into the location history information. It is also preferable to use a method for collecting user entry/exit information for a specific area in an urban space, characterized in that it includes, and in addition, each of the n area lines does not overlap with each other. It is also desirable to use the method of collecting user entry and exit information.

In addition, the system for collecting urban planning facility use information according to the present invention includes a location information providing server, an information collecting server, and a setter terminal, and the information collecting server is applied to a specific area in an urban space according to one of the above-described methods. It is desirable to use an urban planning facility usage information collection system that collects information about entering and entering users of Korea.

As described above, according to the present invention, after storing the location information for each of a plurality of area lines surrounding an arbitrary specific area using a setter terminal, a method for determining whether the user terminal crosses the corresponding area lines. Since it judges whether or not to enter a specific area, there is an effect of being able to determine whether all users who have a user terminal and enter or exit a specific area can enter or exit.

In addition, since the present invention can determine whether a user with a user terminal exists in a specific area or has gone out according to whether a plurality of area lines surrounding a specific area have been sequentially crossed. In addition to being able to easily identify the maximum number of simultaneous users or the minimum number of simultaneous users for a specific area, it is also possible to quickly and accurately calculate a specific time zone, date, and day of the week when the number of users is crowded or there are few simultaneous users. There is.

In addition, the present invention is not a method of measuring the current position of all user terminals existing in a specific area, but for user terminals that set area lines outside the boundary line of a specific area and pass through the area lines sequentially for a certain time period. However, it is a method of determining whether the base station has advanced inward or outward by judging according to the passing order, so even if there is an area in which the base station radio wave does not reach, it is possible to judge the existence of all user terminals in a specific area. There is an advantage to be able to.

In addition, since the present invention forms area lines surrounding the specific area with a setter terminal for a specific area and determines whether or not the user terminal enters or exits using the location information of the area lines, a predetermined area or a fixed area There is an advantage of being able to accurately determine whether users have entered or not entered into a specific area arbitrarily determined according to need, as well as determining access to facilities.

The present invention also determines whether a user with a user terminal has passed while exiting a specific area or has passed while entering a specific area, because it is determined based on the passing or not and the passing order of a plurality of area lines. It can have an effect.

In the present invention, since it is possible to determine whether or not the user terminal has passed by using three or more area lines, even if a location measurement error occurs in one area line, it is possible to judge only by measuring the remaining area lines. There is an effect that can minimize the possibility.

In addition, the present invention does not measure the location of all user terminals in the corresponding area and the neighboring area, but by using HLR information surveyed through the setter terminal, it is possible to specify the judgment target terminal and determine only the judgment target terminals. Therefore, when the location information providing server collects location information for a user terminal, it is possible to reduce the load burden, thereby reducing hardware resources such as servers or networks.

The present invention also determines the location of the user terminal by receiving the location history information of the user terminal from the location information providing server of all mobile communication companies, so that even if the mobile communication company to which the user terminal is subscribed is different, all user terminals can enter and exit a specific area. It has the effect of judging information.

In the present invention, it is also possible to measure the entry/exit information for a user terminal carrying a specific area after determining a specific area to determine whether all entry/exit or not, but once the specific area is determined, the previous access There is an advantage of being able to judge the access information for the user terminal that was previously performed and even afterwards.

In the present invention, no matter how wide an arbitrary specific area is, if only an area line surrounding the specific area can be set, it is possible to determine whether or not to access a user terminal accessing the specific area. The purpose of this is to provide a method to accurately determine whether users are entering or not even in a large area such as a plaza or green area, and to provide a system for providing information on using urban planning facilities for this.

In addition, in describing the present invention, when it is determined that a detailed description of the known technology may unnecessarily obscure the subject matter of the present invention, a detailed description thereof is provided as it is already well known in the technical field among known technologies related to the present invention. I will omit it.

The present invention relates to a method and system for determining whether to enter or exit a specific area in an urban space by using a technology for measuring the current location of a mobile phone terminal. As a positioning technology that can determine the current location of a mobile phone terminal, a GPS method using a GPS receiver and a cell method using base station information can be used.In the case of the GPS method, the GPS receiver must always be turned on in the mobile phone terminal to ensure positioning is not possible. Because it is possible, it is not useless if the user turns off the GPS reception function because he is reluctant to expose the location, and there are problems such as that it is possible to always operate an application that provides GPS information. It is possible to track the location of the terminal of the device, but it is impossible to track the location of all unspecified terminals. Therefore, the Cell method is used rather than the GPS method, and the Cell method is a method of determining the location based on the base station of the mobile communication company. However, there is a disadvantage that it is possible only for people who subscribe to the same mobile carrier, and has a large error range of 200m to 1,500m. Nevertheless, the reason Cell method is widely used is because positioning is possible indoors, location determination is possible without adding additional hardware or software to the terminal, and location determination is possible only with base station information regardless of the user's intention. to be.

Specific implementation methods of the Cell method include Cell ID method, Enhanced Cell ID method, and triangulation. The Cell ID method uses the Cell ID assigned to each base station, and the mobile station uses the base station registered as the current Home Location. This is a method of judging by the current location. Therefore, there is a disadvantage in that it is difficult to make precise determination because the error range is as much as the size of the base station cell radius. In addition, the Enhanced Cell ID method is a positioning method that increases accuracy by adding distance information between the base station and the terminal to the Cell ID method. In measuring the distance between the base station and the terminal, the received signal strength (RSS) decreases according to the distance.In urban areas, the distance measurement can be accurately performed due to the diffuse reflection of radio waves caused by obstacles such as buildings. There is a problem that it cannot be done. In addition, triangulation is a method of receiving distance information from a plurality of base stations to a terminal and determining the location of a terminal through it.There are methods such as AOA, TOA, and TDOA, of which AOA (Angle of Arrival) is a user's This is a method in which the angle of arrival of the radio wave coming from the terminal is measured at the base station and positioned. Therefore, there is an advantage in that the location can be determined with only two base stations, but since each base station requires an antenna capable of receiving radio waves from various angles, it is difficult to commercialize the positioning method. In addition, the TOA (Time of Arrival) is a method of positioning by using a signal arrival time with a signal received from two other base stations centering on one base station receiving a signal from the terminal. It is a positioning method that is difficult to commercialize as both the terminal and the base station must have absolute time synchronization. Lastly, there is a Time Difference of Arrival (TDOA), which is a technology that uses a difference in time between a signal from a base station to which a user belongs and a signal from neighboring base stations, and unlike TOA, a reference time is not required. However, time synchronization between APs is necessary, and in the case of passing through a repeater between the base station and the user, the value is held long and may cause an error.

FIG. 1 is a trigonometric method of positioning the current position of a mobile phone terminal 30 by using the arrival time of the radio wave from the base station 50 to the mobile phone terminal 30, such as TDOA (Time Difference of Arrival), among such conventional techniques. This is a diagram for explaining a position measurement error that occurs in the case of a problem. As shown in FIG. 1, when determining the current location of the mobile phone terminal 30a or determining whether the mobile phone terminal 30a is located within a specific area 80, at least two base stations 50a The distance is determined by measuring the arrival time of the radio waves from .When two distances (L1, L2) are measured by the TDOA method from the two base stations (50a, 50b), the distance (L0) between the base stations (50a, 50b) ) Is fixed, so it is possible to specify the point P1 where the mobile phone terminal 30a is located. However, even if another mobile phone terminal 30b exists at a point P2 other than the point P1 where the mobile phone terminal 30a is located, the same two and the same distances (L1, L2) are measured, so the mobile phone terminal at the point P2 (30b) It may also be determined that it exists in the specific region 80. Therefore, in order to accurately determine the location of the mobile phone terminal 30c in the TDOA method, it is possible for the mobile phone terminal to receive radio waves from at least three base stations. As shown in FIG. 1, from the third base station 50c to P1 and P2. Since the distances are different (L3, L3'), even if the distances from the two base stations 50a and 50b to P1 and P2 are the same, P1 and P2 can be identified as different locations by the third base station 50c. It can be.

However, in reality, the mobile phone terminal 30 cannot always receive signals from three or more base stations within an urban space, and there are many places where only two base stations are received, and even receive signals from only one base station. There are also cases where there is no choice but to. In addition, even if the distance is measured using the TDOA method, there are too many cases where the measurement error is severe due to diffuse reflection, interference, attenuation, etc. of radio waves caused by obstacles such as buildings, making accurate positioning difficult in urban areas where buildings are concentrated. Therefore, for accurate location measurement, there is no choice but to use a fingerprinting method in which the signal strength of the mobile phone terminal 30 is measured for all locations, measured for each received signal, stored, and then compared. Not only is it difficult in reality to measure, but even if it is implemented, a location that is measured with the same distance from a location where only one base station signal is received appears as a number of points, so there is not only a positioning error, but also a new or changed base station. When the base station signal reception environment changes due to a new construction of a nearby building, there is a problem in that it has to be dealt with one by one.

The present invention solves these problems and provides a method and system for collecting information on entering and exiting users for a specific area in an urban space. 2 shows a preferred configuration diagram of the urban planning facility use information collection system 10 for collecting user entry and exit information for a specific area in an urban space according to the present invention. It is preferable that the present invention includes an information collection server 100, a location information providing server 200, and a setter terminal 300 as shown in FIG. 2. Here, the location information providing server 200 is a server in which mobile telecommunication companies collect and provide location information for their subscribers. In order to measure all users entering and exiting a specific area, a service is provided in the country or region. It is desirable to have location information provided by all mobile carriers. Therefore, it is preferable that the location information providing server 200 includes each location information providing server 200 serviced by all mobile communication companies.

The location information providing server 200 analyzes the signal of the setter terminal 300 received by the base stations 500 by using one or more of a number of known methods to analyze the difference in arrival time of radio waves, and then the setter terminal ( It is preferable to transmit current location information of 300), that is, distance information measured from each base station 500 to the setter terminal 300 to the information collection server 100 through the communication network 900. And the information collection server 100 stores the location information of the setter terminal 300 transmitted by the location information providing server 200 as line location information while the setter terminal 300 moves along a predetermined line. It is desirable to do it. And the information collection server 100 compares the movement information of the user terminal 400 using the stored line position information of the setter terminal 300, the line that the setter terminal 300 has passed by the user terminal ( 400) crosses and passes.

FIG. 3 illustrates a concept of collecting location information on an area line surrounding a specific area 800 by using the setter terminal 300 in the present invention. Hereinafter, a method of collecting line position information on the area line L surrounding the specific area 800 using the setter terminal 300 will be described with reference to FIG. 3. First, when an arbitrary specific area 800 to identify user entry/exit within the urban space is determined, n different area lines (L1 to Ln) surrounding the specific area 800 are set, and then the setter terminal It is preferable that the person (the setter) carrying the 300 moves sequentially along the n number of area lines L1 to Ln. The setter carrying the setter terminal 300 may move on foot, and if the specific area 800 is wide, it is possible to move by boarding a moving means such as a vehicle. As shown in FIG. 3, each of the n area lines L1 to Ln is preferably not overlapped with each other, and it is more preferable not to overlap with the specific area 800. However, the last n-th area line Ln at the innermost side may be a boundary line of the specific area 800. In addition, it is preferable that the interval between the n area lines (L1 to Ln) have a certain distance or more, which is different from the signal received from the base station 500 when the setter terminal 300 changes the area line. It should be received, but if it is too close, there is a possibility that the setter terminal 300 may receive the same signal even though the area line is different. Most preferably, the separation distance between the area lines is maintained at 5m or more. However, if the geographic situation is difficult, it is possible to make it within 5m.

When the setter terminal 300 moves sequentially along each of the n area lines (L1 to Ln), the real-time position value of the setter terminal 300 measured by each of the base stations 500a, 500b, and 500c, ' The arrival time of the radio wave from the setter terminal 300 to each of the base stations 500a, 500b, and 500c is continuously changed according to the movement of the setter terminal 300, and the changed real-time position value is the location information. It is preferable to measure in the providing server 200 and provide it to the information collecting server 100, and the information collecting server 100 to store this as line position information for the area lines. The real-time location values of the setter terminal 300 based on the base station information measured and transmitted by the location information providing server 200 are stored as the line location information for each of the n area lines L1 to Ln. , With the outermost area line of the n area lines L1 to Ln as the first line L1 and the innermost area line as the nth line Ln, the first line L1 It is preferable to store the first line position information to the nth line position information respectively corresponding to each of the n-th lines Ln.

The location information is an actual measurement value for the distance to the setter terminal 300 measured by the TDOA method in each base station 500, and since diffuse reflection or interference of radio waves occurs due to an obstacle such as a building, the base station 500 ) To the setter terminal 300 may be different from the actual distance (reach time of radio waves). However, even if it is different from the actual distance, it is a unique value actually measured at the corresponding location, and since the user terminal 400 will also be measured with the same value later, even if it has location information different from the actual location, it can be utilized regardless of this. That is, the location information collected by the setter terminal 300 in the present invention is measured as a line fingerprint of each of the n area lines (L1 to Ln), and the same when the user terminal 400 reaches the same position later. It is identified as location information, and it is to check whether the user terminal 400 represents the same value at that location and passes through it, so even if it has a location information value different from the actual location, it is not a value measured as an actual location. In the invention, it can be utilized. Therefore, as shown in FIG. 3, a building is blocked between the setter terminal 300 and the base station 500c, and the radio waves are reflected to arrive (refer to the red arrow), and thus, even if the arrival time is longer, it is stored as it is. This is because, when the price of the user terminal 400 passes through the location later, it is also the same environment, so the same arrival time comes out.

Meanwhile, in addition to this, the information collection server 100 receives real-time changes to the home location register (HLR) of the setter terminal 300 included in the base station information from the location information providing server 200, It is desirable to save it as HLR information after removing. The HLR information is for specifying only the user terminals 400 entering and leaving the specific area 800 among the user terminals 400 to the determination target terminals 400a, the location information providing server 200 When a user terminal 400 having one of the base stations 500 included in the HLR information as a home location occurs, it is specified as the determination target terminal 400a, but while the home location is maintained the same It is desirable to measure only the location information. The present invention checks whether the user terminal 400 has passed the n number of area lines (L1 to Ln) to determine whether it has entered the specific area 800 or has exited from the specific area 800 Therefore, if the setter terminal 300 measures the location information only for the user terminals 400 that have the base stations set as Home Locations as Home Locations while moving on the n number of area lines (L1 to Ln), It is possible to include all user terminals 400 in and out of the specific area 800.

In this way, the information collection server 100 stores first line position information to n-th line position information respectively corresponding to each of the first line to the n-th line provided from the location information providing server 200. And, if real-time changes to the HLR of the setter terminal 300 among the base station information are provided from the location information providing server 200, and the duplicate values are removed and stored as HLR information, the specific area 800 ) Is ready to measure the access status of the user terminal 400.

When the user terminal 400 is ready to measure the entry/exit status of the specific area 800, the information collection server 100, the location information providing server to determine the access status of the user terminal 400 For 200, among the user terminals 400, the determination target terminals 400a having a high probability of entering or leaving the specific region 800 during a certain time period are specified, and during the certain time period. It is desirable to request that the location history information be provided. When the location information providing server 200 is requested to provide the location history information, a user terminal 400 having one of the base stations 500 included in the HLR information as Home Location during the predetermined time period is generated. In this case, this is specified as the determination target terminal 400a, and for the determination target terminal 400a, movement information including location information and measurement time while the home location is maintained is collected and converted into the location history information. It is desirable to include. Here, it is possible to set the time zone temporarily, for example, as a few hours from a specific time on a specific day, but it is also possible to set a specific time zone every day for a certain period of time, 24 hours a day, all week, every Monday, all day, etc. It is also possible to set a time zone or a long time as a section. In addition, it is possible to use the setter terminal 300 to store the location information for the area line L and then for a certain time period, but the information for a certain time period before storing the location information for the area line is Of course it is also possible to analyze it. Therefore, when a person visiting a specific facility or area is found to be a confirmed infectious disease, the facility or area is designated as the specific area 800 to quickly and accurately determine the people who were in the same space during the time period during which the confirmed person visited the specific area 800. It can be done.

The information collection server 100, which receives the location history information for the determination target terminals 400a from the location information providing server 200 for the predetermined time period, transmits the location history information to the first line location information or Compared with each of the n-th line location information, if there is matching location information, the matching location information and the measurement time are stored as pass information for the determination target terminal 400a, wherein the first line to the first line It is preferable to store the first pass information to the nth pass information to correspond to each of the nth lines. In addition, it is preferable to determine whether the terminal 400a to be determined having the first pass information and the n-th pass information has entered or has advanced to the specific area 800.

Here, the method of determining whether or not the determination target terminal 400a has entered the specific region 800 includes first passing information having a measurement time faster than the measurement time of the n-th passing information, The determination target terminal 400a not having the passage information for a predetermined period of time after the measurement time of the n-th passage information is determined to be a user terminal 400 having an entry history to the specific region 800, and the The first pass information having a measurement time that is later than the measurement time of the n pass information, but does not have the pass information for a certain period of time before the measurement time of the n-th pass information, and the measurement time included in the first pass information From then on, it is preferable to determine the user terminal 400 having an advance history from the specific area for the terminal 400a to be determined that does not have the passage information even for a certain period of time.

However, only the determination target terminals 400a having both the first pass information to the n-th pass information are made to determine whether they have entered the specific area 800 or not, and the determination target terminal ( When 400a) records the measurement time in order from the first pass information to the n-th pass information, it is determined that it has entered the specific area, and the determination target terminal 400a In the case of recording the measurement time in order up to one pass information, it is also desirable to judge that it has advanced from the specific area and has gone out.

4, when the user at point A carries the user terminal 400, passes through the area line, enters the specific area and moves to the point B, the user terminal 400 At least in the process of passing the first line, one of the base stations that the setter terminal 300 used as the Home Location in the process of collecting the location information for the area line is also the user terminal 400 as the Home Location. The location information providing server 200 specifies the user terminal 400 passing through the first line as the determination target terminal 400a, and the determination target terminal 400a starts from the first line. When passing through the n-line, the third line, when passing through the point i1, there will be location information that matches the content stored in the location information of the first line. The time will be stored in the first pass information, and in the process of passing through the points i2 and i3, the second pass information and the third pass information will be stored respectively. At this time, the measurement time of the third pass information will be later than the measurement time of the first pass information, and the moment from the moment entering into the specific area 800 through the i3 point until exiting the specific area again for a certain period of time, the Since there is no need to cross the area line (L), there will be no record of the passage information, so the information collection server 100 passes the i3 point and determines the determination target terminal 400a at a time point. It is determined that it has entered the area 800. Here, a certain time may be determined according to the situation of the specific area 800. When the interval between the area lines is short, it is preferable to set it to a few seconds or more, and when the interval between the area lines exceeds 10m, it is set to about several tens of seconds. It is desirable to do. This is to filter out the determination target terminals 400a that have not entered the specific area 800 as a result by reaching the i3 point and then returning to the i2 point.

In addition, after entering into the specific area 800 and staying at point B, for example, the terminal 400a to be determined will not have recorded the passage information after the time of staying. And if the point B to the point C, the third line through the first line in order to go out, when reaching the point o3, point o2, and point o1 in order, the third pass information, the second pass information, and Each of the first pass information will be measured, and at this time, the first pass information having a measurement time that is later than the measurement time of the third pass information will be obtained, and the pass information for a certain period of time before the measurement time of the third pass information. The information collection server 100 does not have the pass information for the predetermined time period from the measurement time included in the first pass information, and thus the specific region for the determination target terminal 400a. It is judged that it advanced from (800) and went out.

Meanwhile, in the present invention, the terminal to be determined having the passage information corresponding to the m-th line between the first line and the n-th line and the terminal to be determined having the n-th passage information entered the specific region. It is preferable to determine whether or not, but does not have the first passing information having a measurement time faster than the measurement time of the n-th passing information, but mth having a measurement time faster than the measurement time of the n-th passing information To determine as the user terminal 400 having a history of entering the specific area with respect to the terminal 400a to be determined that has passage information and does not have the passage information for a certain period of time after the measurement time of the n-th passage information It is preferable to do, and does not have first pass information having a measurement time later than the measurement time of the n-th pass information, but has m-th pass information having a measurement time that is later than the measurement time of the n-th pass information, the For the determination target terminal 400a that does not have the passage information for a certain period of time before the measurement time of the n-th passage information, and does not have the passage information for a certain period of time after the measurement time included in the m-th passage information It is preferable to determine as the user terminal 400 having an advance history from the specific area.

In addition, it is desirable to estimate whether or not the terminal to be determined 400a having the first pass information and the m-th pass information has entered the specific area, which is later than the measurement time of the first pass information. It does not have the n-th passing information having a time, but has the m-th passing information having a measurement time that is later than the measurement time of the first passing information, and the passing information is stored for a certain time after the measurement time of the m-th passing information. It is preferable to estimate that a terminal to be determined that does not have an entry history to the specific area is a user terminal, and does not have the n-th pass information having a measurement time faster than the measurement time of the first pass information. A measurement time included in the first passing information, without having the passing information for a certain period of time before the measurement time of the m-th passing information, having a measurement time faster than the measurement time of the first passing information From then on, it is preferable to estimate that a terminal to be determined that does not have the passage information for a certain period of time is a user terminal having an advance history from the specific area.

In this way, when the number of the area lines is 3 or more and the m-th pass information is used, the first or last area line is formed due to instantaneous radio wave interference in the process of the determination target terminal 400a passing through the area lines. Even when the location information is not included in the location history information at the moment of passage, it is possible to determine whether to enter or exit the specific area 300 with only the remaining area lines. That is, for the determination target terminal 400a that cannot be determined using the first pass information and the n-th pass information because there is no first pass information or the n-th pass information, the m-th pass information is used. It is possible to determine whether to enter or exit the specific region 300. In addition, when three or more area lines (L) are used, even if the measured values at a specific location are different from the actual locations, the measured values measured at the locations passing through each of the three or more area lines (L) are identical. If it is, there is an advantage of being able to judge more accurately. For example, when the determination target terminal 400a crosses three or more area lines L, the location information of each of the three area lines is measured by the setter terminal 300 as a completely wrong value. Even if the values coincide with the values measured when the determination target terminal 400a passes through three area lines, this means that the determination target terminal 400a passes through the three or more area lines (L). This is because it is almost certain in probability. However, if there is one area line, since there may be another location measured by the same value as the location value measured by the setter terminal 300, the determination target terminal crosses the area line L. You won't be sure if it's going to happen or if you're going through another location. However, in the present invention, since it is determined that the determination target terminal 400a crosses the n number of area lines (L), it is possible to accurately measure whether the area line (L) passes. In this case, if n is 2 If it is more than 3, it is possible to judge more accurately in probability. That is, the probability that two coincidentally coincide is much lower than the probability that one coincidentally coincides, and since the probability of three coincidence is even lower, the intersection of the determination target terminal 400a matching n area lines L is The higher n, the higher the reliability. However, when the number of area lines is too large, a lot of effort and time are required to measure the area line L, so that n is most preferably 3.

On the other hand, FIG. 5 shows another embodiment of setting an arbitrary specific region in the present invention. In the present invention, the specific region 800 is defined as a standardized region divided by a square or a straight line as in FIG. 4. In addition to being able to determine whether or not the user terminal 400 is in or out, it is also possible to accurately determine whether or not the user terminal 400 enters or exits a specific area 800 formed of an arbitrary closed curve as shown in FIG. There will be. Accordingly, it is possible to set the specific area 800 along the boundary line of an urban park or a natural park.

In addition, the information collection server 100 receives real-time changes to the HLR of the setter terminal 300 among the base station information from the location information providing server 200 (s160), and removes the duplicate values, and obtains the HLR. It is desirable to store it as information (s170). When the storage of the location information of the first line is terminated, the information collection server 100 requests the setter terminal to move to the next area line (L) and move along the area line (L), and the s110 Repeating the processes from s170 to s170, but performing such a process until the n-th line is reached, the storage of the location information of the first line to the location information of the n-th line surrounding the specific region 800 is completed.
