  The information management apparatus 600 includes a user ID for identifying a user of the mobile device 100 and user attribute information (age, gender, address) associated with the user ID. An information storage unit 610; and an attribute table calculation unit 611 that creates an attribute table in which user attribute information is classified for each attribute based on information stored in the user-specific attribute information storage unit 610. Here, the information related to the user of the mobile device 100 stored in the user-specific attribute information storage unit 610 is, for example, information registered by the user with the service provider company of the motivation 100 when the mobile device 100 is contracted to start use Is used. As shown in FIG. 3, the user-specific attribute information storage unit 610 stores a user-specific attribute table for managing user-specific attribute information (age, sex, address) for each user ID.

  Also, the information management device 600 is received by the information receiving unit 601 that receives information (mobile device information, time information, location information, output trigger information) transmitted from the information communication unit 301 of the RNC 300 and the information receiving unit 601. The attribute specifying unit 602 for specifying to which attribute of the attribute table the user of the mobile device 100 corresponding to the information (mobile device information, time information, position information, output trigger information) and the information receiving unit 601 Of the received information (mobile device information, time information, location information, output trigger information), attributes are excluded using information (time information, location information, output trigger information) excluding mobile device information that can identify the mobile device.

That is, the evaluation result or the prediction result may be displayed and output on a display or the like, may be printed out from a printer or the like, or may be output both in display and printing.

[Processes executed in the user information management system]
Next, details of a procedure for creating an attribute table performed by the attribute table calculation unit 611 will be described with reference to FIG. Here, the attribute table calculation unit 611 creates the attribute table by totaling the user-specific attribute information stored in the user-specific attribute information storage unit 610 for each attribute ID, and the attribute-specific position management table creation unit 603. Is to create a position management table for each attribute for each attribute ID of the attribute table.

  First, the attribute table calculation unit 611 newly creates a blank attribute table (step S1). Specifically, as shown in FIG. 5, a table in which only items of attribute ID, age, gender, address, and number of people are input is created. In step S7, which will be described later, this attribute table is assigned an attribute ID for each age (10's, 20's, 30's, 40's ...), sex (male, female), and address (address in units of street names). The number of persons can be counted for each attribute ID.

  Next, the attribute table calculation unit 611 refers to the attribute information associated with a predetermined user ID in the user-specific attribute table (FIG. 3) stored in the user-specific attribute information storage unit 610 (step S2). . In step S2, immediately after the start of this process, the user attribute information corresponding to the user ID in the top row of the attribute table for each user in FIG. 3 is referred to. When the process proceeds from step S6 described later to step S2 again, the attribute corresponding to the user ID in the next (one lower row) row of the user ID in the user-specific attribute table referred to in the previous processing in step S2 Browse information.

  Next, the attribute table calculation unit 611 determines whether there is an attribute ID corresponding to the attribute information referred to in step S2 in the attribute table (step S3). For example, when referring to the attribute information (age: 31, gender: female, address: Yokohama city) of the user ID = 5 in step S2, the attribute ID corresponding to the user ID = 5 is shown in FIG. Since = 2 exists, it is determined in step S3 that the corresponding attribute ID exists.

  If there is a corresponding attribute ID (step S3: YES), the attribute table calculation unit 611 adds 1 to the number of corresponding attribute IDs in the attribute table (step S4).

  On the other hand, if the corresponding attribute ID does not exist (step S3: NO), the attribute table calculation unit 611 adds a line to the attribute table and assigns the attribute ID, and refers to the added line in step S2. Attribute information (age, sex, address) corresponding to the user attribute information is input and the number of persons is set to 1 (step S7). Next, the attribute-specific position management table creation unit 603 newly creates an attribute-specific position management table corresponding to the attribute ID newly given in step S7 (step S8). Specifically, as shown in FIG. 6, the attribute-specific position management table is a table in which only items of time, position information, and output trigger are input for each attribute ID.

  After adding the number of people in the attribute table (step S4) or creating the location management table for each attribute (step S8), the attribute table calculation unit 611 follows the user ID of the user-specific attribute table referenced in the immediately preceding step S2. Reference is made to the user ID in the row (one lower level) (step S5). The attribute table calculation unit 611 determines whether or not the user ID exists in the next (one lower row) referenced in step S5 (step S6). If the user ID exists (step S6: YES), step S2 is performed. , The attribute information corresponding to the user ID is referred to, and thereafter the above-described processing is repeated. On the other hand, if no user ID exists (step S6: NO), it is assumed that all user IDs in the user-specific attribute table are classified by attribute and input to the attribute table is completed. End the process.

  In this way, from the user-specific attribute information (user-specific attribute table) including the user-specific ID that can specify the user, the user ID that does not specify the user is not included, and the user's An attribute table classified for each attribute can be created.

  Next, the details of the procedure for creating the attribute-specific position management table will be described with reference to FIG. Here, the attribute-specific location management table is obtained by removing information on mobile devices 100 transmitted from the RNC 300 (mobile device information, time information, location information, output opportunity information) from mobile device information that can identify mobile devices. This is input to the attribute-specific position management table created by the creation unit 603.

  First, the information receiving unit 601 of the information management device 600 receives information (mobile device information, time information, position information, output trigger information) related to the mobile device 100 transmitted from the information communication unit 301 of the RNC 300 (step S11). . Here, a user ID is used as mobile device information for identifying a mobile device, and the mobile device and user attribute information are associated with each other. Specifically, as shown in FIG. 8A, the information receiving unit 601 is mobile device information: user ID = 1, time information: 10:00, location information: (X1, Y1), output opportunity information. : Receive information on cross-area registration.

  Next, the attribute specifying unit 602 refers to the user-specific attribute table stored in the user-specific attribute information storage unit 610 and the attribute table calculated by the attribute table calculation unit 611, and is received by the information receiving unit 601. The attribute ID in the attribute table to which the user of the mobile device 100 corresponding to the information belongs is specified (step S12). Specifically, when the attribute table for each user and the attribute table are as shown in FIG. 8B, and the information regarding the mobile device 100 received by the information receiving unit 601 is as shown in FIG. The attribute ID corresponding to the mobile device information (user ID = 1) received by the information receiving unit 601 is attribute ID = 1.

  Next, the attribute-specific position management table creation unit 603 stores information (time information, time information, Position information and output opportunity information). Specifically, when the information related to the mobile device 100 received by the information receiving unit 601 is as shown in FIG. 8A, as shown in FIG. 9, the attribute-specific position management table corresponding to attribute ID = 1. Furthermore, 10:00 as the time information, (X1, Y1) as the position information, and information on the area crossing position registration as the output trigger information is input. The attribute-specific position management table input in step S13 is previously created by the attribute-specific position management table creating unit 603 (FIG. 4: processing in step S8) when creating the attribute table.

  In this way, by creating the attribute-specific position management table, the position information of the mobile device 100 is classified for each user attribute and can be managed. Further, since the attribute-specific position management table is obtained by removing information (user ID) that can specify the mobile device or the user, the user is specified from the information input to the attribute-specific position management table. It is a table that can not.

  Next, a process in which the user information extraction unit 604 extracts user information based on the attribute-based position management table will be described. Here, the user information extraction unit 604 extracts a population distribution for each user attribute and a population flow rate (people flow) for each user attribute from the attribute position management table.

  First, the details of the process in which the user information extraction unit 604 extracts the population distribution by user attribute will be described with reference to FIG. Here, the position information of the mobile device 100 at a desired time is extracted from the position management table by attribute of the desired attribute, and the population distribution at the desired time of the user with the desired attribute is extracted based on the extracted position information. Is. In addition, the user information extraction unit 604 receives an instruction from the user of the user information management system 10 to extract the population distribution at a desired time of a user having a predetermined attribute through an input device (not shown). The process of extracting the population distribution is started.

  When there is an instruction to start the population distribution extraction process, the user information extraction unit 604 refers to the attribute table calculated by the attribute table calculation unit 611, and a desired attribute ID corresponding to the population distribution extraction instruction, The number of people is extracted (step S21). For example, the user information extraction unit 604 is instructed to extract the population distribution of users corresponding to “20's, male, address: Yokosuka City”, and the attribute table calculation unit 611 performs FIG. When the attribute table shown in FIG. 5 is calculated, the user information extraction unit 604 sets the attribute ID = 1 and the number of people: 3 as the attribute ID and the number of people that match the attribute condition of “20s, male, address: Yokosuka”. To extract.

  Next, the user information extraction unit 604 refers to the attribute-specific position management table corresponding to the attribute ID extracted in step S21, and obtains the position information at a desired time instructed when extracting the population distribution as a step. The number of persons extracted in S21 is extracted (step S22). Here, the user information extraction unit 604 extracts position information corresponding to the time information after the desired time instructed when extracting the population distribution for the number of people. Specifically, the attribute ID extracted in step S21 is attribute ID = 1, the number of people: 3, the desired time instructed when extracting the population distribution is 10:00, and the attribute ID = 1 11B, the user information extraction unit 604 determines that the position information (X1, Y1) of the time after 10:00 from the attribute-specific position management table. , ... are extracted.

  Next, the user information extraction unit 604 tabulates the position information extracted in step S22 in a desired area unit (step S23), and outputs, for example, a population distribution map of desired attributes as shown in FIG. The data is output via 605 (step S24). In the population distribution map shown in FIG. 12, the map showing roads and the like is divided into predetermined area units, and the color distribution of each area is changed based on the number of users. Represents.

  As described above, the user information extraction unit 604 uses the attribute-specific position management table that does not include information (user ID) that can identify the user of the mobile device 100 to determine the population distribution of users having a desired attribute. Can be extracted.

  Next, details of a process in which the user information extraction unit 604 extracts a population flow rate by user attribute will be described with reference to FIG. Here, the location information of the mobile device 100 in the desired time zone is extracted from the location management table for each desired attribute, and the population flow rate in the desired time zone of the user having the desired attribute is calculated based on the extracted location information. To extract. Also, the user information extraction unit 604 receives an instruction from the user of the user information management system 10 to extract the population flow rate in a desired time zone of a user with a predetermined attribute through an input device (not shown). Then, the population flow extraction process is started.

  When there is an instruction to start the population flow extraction process, the user information extraction unit 604 refers to the attribute table calculated by the attribute table calculation unit 611, and a desired attribute ID corresponding to the population flow extraction instruction, The number of people is extracted (step S31). For example, the user information extraction unit 604 is instructed to extract the population flow rate of the user corresponding to “20s, male, address: Yokosuka City”, and the attribute table calculation unit 611 performs FIG. When the attribute table shown in FIG. 5 is calculated, the user information extraction unit 604 sets the attribute ID = 1 and the number of people: 3 as the attribute ID and the number of people that match the attribute condition of “20s, male, address: Yokosuka”. To extract.

  Next, the user information extraction unit 604 refers to the attribute-specific position management table corresponding to the attribute ID extracted in step S31, and obtains the position information of the desired time zone instructed when extracting the population flow rate. The number of persons extracted in step S31 is extracted (step S32). Here, the user information extraction unit 604 extracts the position information corresponding to the time information after the start time of the desired time zone instructed when extracting the population flow rate for the number of people extracted in step S31, Furthermore, the position information corresponding to the time information after the end time of the desired time zone is extracted for the number of people extracted in step S31. Specifically, the attribute ID extracted in step S31 is attribute ID = 1, the number of people: 3, and the desired time zone instructed when extracting the population flow rate is 10:00 to 11:00. When the attribute-specific position management table corresponding to attribute ID = 1 is as shown in FIG. 14B, the user information extracting unit 604 uses the attribute-specific position management table to obtain time information after 10:00. Are extracted, and three pieces of position information (X2, Y2),... Corresponding to time information after 11:00 are extracted. .

  Next, the user information extraction unit 604 aggregates the position information of the desired time zone extracted in step S32 in units of desired areas, and extracts the flow rate of the user moving between the areas (step S33). . Specifically, the user information extraction unit 604 aggregates the position information extracted for a predetermined number of people from the start time of the desired time zone in a desired area unit, and extracts the population distribution at the start time of the desired time zone. To do. Next, the user information extraction unit 604 aggregates the position information extracted for a predetermined number of people from the end point of the desired time zone in a desired area unit, and extracts the population distribution at the end point of the desired time zone. The user information extraction unit 604 extracts a population flow rate in a predetermined time zone by calculating a difference between two population distributions of a start point and an end point of a desired time zone.

  The user information extraction unit 604 outputs the extracted result to the output unit 605, for example, as a population flow map with a desired attribute as shown in FIG. 15 (step S34). In the population flow map shown in FIG. 15, a map in which roads and the like are described is divided in predetermined area units, and the movement of the population is represented by using arrows across the areas. In addition, the flow rate of the user is represented by changing the color of the arrow according to the amount of movement of the population.

  As described above, the user information extraction unit 604 uses a desired attribute in a desired time zone using the attribute-specific position management table that does not include information (user ID) that can identify the user of the mobile device 100. The population flow of the person can be extracted. In addition, it is possible to extract the population flow rate of the user of the mobile device 100 more accurately by extracting the movement route of the mobile device 100 using the output trigger information and the location information of “area crossing location registration”. .

  As described above, in the user information management system 10 according to the present embodiment, the information (user ID) that can be used to identify the user of the mobile device 100 created by the attribute-based position management table creation unit 603 is removed. With the attribute-specific position management table, the position information of the mobile device 100 can be managed for each user attribute. Further, an attribute ID corresponding to user information to be extracted is extracted using an attribute table from which information that can identify the user of the mobile device 100 is removed, and an attribute-specific position management table corresponding to the extracted attribute ID is used. Thus, user information such as the population distribution and population flow of the user of the mobile device 100 is extracted. In this way, user information can be extracted using an attribute table and an attribute-specific position management table from which information that can identify a user is removed without using information that can identify the user.

[About action and effect]
Next, the operation and effect of the user information management system 10 of this embodiment will be described.

  The user information management system 10 and the method thereof in this embodiment include an RNC 300 (radio network control device) that performs radio connection control of the mobile device 100 and an information management device 600 that can transmit and receive information to and from the RNC 300. Consists of including. The RNC 300 includes an information communication unit 301 that specifies the location information of the mobile device 100, acquires mobile device information that can specify the mobile device, and transmits the location information and the mobile device information to the information management apparatus 600. The information management apparatus 600 includes a user-specific attribute information storage unit 610 that stores user-specific attribute information including information that can identify a user of the mobile device 100, and a user-specific attribute information storage unit 610. An attribute table calculation unit 611 that classifies user-specific attribute information for each predetermined attribute, calculates an attribute table based on user-specific attribute information excluding information that can identify the user of the mobile device 100, and an information communication unit 301 An information receiving unit 601 that receives position information and mobile device information transmitted from the user, user-specific attribute information stored in the user-specific attribute information storage unit 610, and an attribute table calculated by the attribute table calculation unit 611 Based on the attribute specification unit 60 for specifying to which attribute of the attribute table the user of the mobile device specified by the mobile device information received by the information reception unit 601 belongs. And classifying the position information received by the information receiving unit 601 for each specified attribute based on the attribute specified by the attribute specifying unit 602, and creating an attribute-specific position management table based on the position information A location management table creation unit 603; a user information extraction unit 604 that extracts predetermined user information of the mobile device 100 based on the location management table by attribute created by the location management table creation unit by attribute 603; And an output unit 605 for outputting the extraction result by the person information extraction unit 604.

  In addition, the user information management system 10 and the method thereof according to the present embodiment are configured to include a mobile device 100 and an information management device 600 that can communicate with the mobile device 100. The mobile device 100 includes an information communication unit that acquires location information of the mobile device and transmits the acquired location information and mobile device information that can identify the mobile device to the information management apparatus 600. The information management apparatus 600 includes a user-specific attribute information storage unit 610 that stores user-specific attribute information including information that can identify a user of the mobile device 100, and a user-specific attribute information storage unit 610. From the information communication unit, an attribute table calculation unit 611 that classifies individual attribute information for each predetermined attribute and calculates an attribute table based on user-specific attribute information excluding information that can identify the user of the mobile device 100; An information receiving unit 601 that receives the transmitted location information and mobile device information, user-specific attribute information stored in the user-specific attribute information storage unit 610, and an attribute table calculated by the attribute table calculation unit 611 An attribute specifying unit 602 for specifying to which attribute of the attribute table the user of the mobile device specified by the mobile device information received by the information receiving unit 601 belongs, Based on the attribute specified by the sex specifying unit 602, the position information received by the information receiving unit 601 is classified for each specified attribute, and an attribute-specific position management table is created based on the position information. A table creation unit 603; a user information extraction unit 604 that extracts predetermined user information of the mobile device 100 based on the attribute-specific location management table created by the attribute-specific location management table creation unit 603; and user information And an output unit 605 that outputs an extraction result obtained by the extraction unit 604.

  For this reason, the attribute table calculation unit 611 calculates an attribute table based on user-specific attribute information excluding information that can identify the user of the mobile device 100. The attribute-specific position management table creation unit 603 classifies the position information of the mobile device 100 for each attribute based on the attributes of the user specified using the attribute table, and creates an attribute-specific position management table. The attribute-specific position management table calculated in this way does not include information that can identify the user of the mobile device 100, and the position information of the mobile device 100 without using information that can identify the user. (User information) can be classified and managed for each attribute. Also, by extracting predetermined user information of the mobile device 100 based on the attribute-specific position management table, various statistical information can be extracted without using information that can identify the user.

  In addition, according to the user information extraction unit 604 in the present embodiment, the user is specified by extracting the population distribution for each user attribute of the mobile device based on the position information of the attribute-specific position management table. Population distribution information for each attribute can be extracted without using information.

  Further, according to the user information extraction unit 604 in the present embodiment, the user is specified by extracting the population flow rate by attribute of the user of the mobile device based on the position information in the attribute-specific position management table. It is possible to extract population flow information by attribute without using information.

  The present invention is not limited to the embodiment described above.

  For example, in the above embodiment, the number of users belonging to a predetermined attribute is managed using the attribute table, and the position information of the user belonging to the predetermined attribute is extracted from the attribute-specific position management table based on this number of persons. However, without managing the number of users using the attribute table, the number of position information to be extracted from the attribute-specific position management table (the number of users belonging to the attribute) should be grasped and the position information extracted. You can also. Here, as the location registration signal transmitted from the mobile device 100 to the RNC 300, the location registration signal transmitted when the mobile device 100 moves across the location registration area, and the location registration in the location registration area every 54 minutes. It is assumed that a position registration signal that is a signal for obtaining the above is used. Further, when the mobile device 100 transmits a location registration signal when moving across the location registration area, the mobile device 100 resets the timer of the location registration signal to be transmitted every 54 minutes.

  In this case, for example, when six pieces of position information are input between time 10:00 and time 10:54 as in the attribute-specific position management table shown in FIG. Since the location registration signal is transmitted by crossing the location registration area at 00 and time 10:10, and the mobile devices 100 whose locations are specified are located in Yokosuka and Hokkaido, respectively, the mobile devices 100 are different from each other. (Users are different). In addition, since the location registration signal is transmitted by other periodic location registration and the mobile device 100 whose location is specified is also transmitted within the 54-minute cycle, the mobile devices 100 different from each other. It can be said that there is. Therefore, the mobile device 100 whose position information is specified between time 10:00 and time 10:54 is duplicated (for example, the same mobile device 100 is positioned multiple times between time 10:00 and time 10:54). It can be determined that there are six users of the mobile device 100 belonging to the attribute ID = 1, and six pieces of position information are extracted from the attribute-specific position management table. To do.

  Further, for example, when 6 pieces of position information are input between time 10:00 and time 10:54 as in the attribute-specific position management table shown in FIG. 16B, time 10:00 and time The location registration signal transmitted from the same mobile device 100 is transmitted because the location registration signal is transmitted by crossing the location registration area at 10:10, and the mobile devices 100 whose locations are specified are located in the same Yokosuka respectively. It is highly possible that the signals are signals, and it can be determined that the mobile devices 100 are the same. Thus, if the location registration signal transmitted by straddling the location registration area is an area configuration (adjacent area) considered to be the same mobile device 100 (same person), it is regarded as the same person, If the area configuration is not so, it can be determined that the person is another person. In addition, since the location registration signal is transmitted by other periodic location registration and the mobile device 100 whose location is specified is also transmitted within the 54-minute cycle, the mobile devices 100 different from each other. It can be said that there is. Therefore, the mobile device 100 whose location information has been specified between time 10:00 and time 10:54 can be determined that the location information has been specified by the location registration signal transmitted from the same mobile device 100 across the areas. By excluding the position information at 10:00, it can be determined that there are five users of the mobile device 100 belonging to the attribute ID = 1, and five pieces of position information are extracted from the attribute-specific position management table. . In addition, in the midnight zone when there is very little movement of people (when there is almost no transmission of location registration signals triggered by cross-area location registration, and most of location registration signals triggered by periodic location registration) Information may be used to determine the number of people.

  In this way, it is possible to grasp the number of users belonging to a predetermined attribute by referring to the attribute-specific position management table without grasping the number of users by the attribute table, and corresponds to the grasped number of people. It becomes possible to extract a number of pieces of position information.

  Further, in the above embodiment, the user information extracted by the user information extraction unit 604 extracts the population distribution by attribute and the population flow by attribute, but other user information is extracted. May be.
