Description

  INDUSTRIAL APPLICABILITY The present invention is suitable for introducing users with close proximity to an activity range using an identification name such as an SSID (Service Set IDentifier) of an access point device to a computer communication network such as a wireless LAN arranged in a city. The present invention relates to an introduction system, a server device, an introduction method, a service method, and a program that implements these on a computer.

  Conventionally, a service for connecting to the Internet via an access point device to a computer communication network such as a wireless LAN that can be used by the public in a city has been provided. One or a plurality of identifiers called SSIDs (sometimes called ESSIDs (Extended SSIDs)) are assigned to access points of a wireless LAN, and the terminal device refers to the SSIDs so that the terminal device can communicate with a plurality of access points. By selecting one of the points, exchanging necessary authentication and information with the access point, and performing an association process for registering the terminal device in the access point, the terminal device can access the Internet via the access point. It becomes possible to access.

  The technology using such a wireless LAN access point is disclosed in Patent Documents 1 and 2 listed later.

  Here, the technique disclosed in Patent Document 1 is intended to manage the location of a wireless LAN terminal device in real time, and each access point notifies the location management server that an association with each terminal device has been established. The location management server records the location of the access point as the current location of the user based on the notified MAC address of the terminal device.

  By using such a service, it is possible to know the location of other users who are presently nearby, and to introduce the users.

  On the other hand, the technique disclosed in Patent Document 2 adds a distribution information based on text information to a radio wave beacon from an access point and transmits it to a terminal device that has not established a connection with the access point. It is possible to distribute information while suppressing wireless band use.

  However, depending on the type of service provided, it may not be desirable from the viewpoint of privacy to grasp the location of the terminal device in real time.

  On the other hand, even if it is not necessary to be near in real time, such as when an announcement is made to invite people who are active in the same area on a public bulletin board, they want to be able to introduce users to each other There is also a request.

  Furthermore, while providing unexpected encounters to users like bottle mail, there is also a desire to deepen user interaction by introducing users who are relatively close to their places of activity.

  The present invention solves the problems as described above, and introduces users who are close to each other in the activity range by using an identification name such as SSID of an access point device to a computer communication network such as a wireless LAN arranged in the city. It is an object of the present invention to provide an introduction system, a server device, an introduction method, a service method, and a program that realizes these on a computer.

  In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

  An introduction system according to a first aspect of the present invention includes a plurality of terminal devices and a server device, and each of the plurality of terminal devices includes a detection unit, a history storage unit, a history transmission unit, an information reception unit, The server device includes an information display unit, and includes a route storage unit, a history reception unit, an extraction unit, an information transmission unit, and an update unit.

  Here, as a terminal device, a game device or various computers having a wireless LAN communication function capable of detecting a beacon output from an access point device to a computer communication network installed indoors or outdoors is applied. Is typical.

  On the other hand, when the server device is connected to the Internet and is connected to the Internet via an access point device that can use the terminal device, it is typically possible to communicate with each other.

  In each of the plurality of terminal devices, the detection unit detects the identification name of the access point device to the computer communication network.

  Since an access point device to a computer communication network such as a wireless LAN periodically emits a beacon, the SSID or MAC (Media Access Control) address of the access point device included in the beacon is used as an identification name. Is typical. It is technically possible for a third party who does not have a contract with the wireless LAN service provider to receive the beacon and examine the contents of the packet.

  On the other hand, the history storage unit of the terminal device stores a history of detected identification names.

  The simplest form of the history is a list of detected identifiers in time order, but a list of pairs of detected times and detected identifiers, or detected time zones. Various modes such as a list of pairs with identification names can be adopted.

  Furthermore, the history transmission unit of the terminal device transmits history information specifying the history of the stored identification name to the server device when communication with the server device is enabled via the access point device of the detected identification name. To do.

  In general, an access point device for a computer communication network cannot be used for connection to the Internet unless it is used at home or has a contract with a service provider. When such a condition is satisfied and the terminal device can communicate with the server device, the history transmission unit transmits the history of the identification names stored so far to the server device.

  At this time, if the transmission is successful, the history of the identification name may be deleted immediately, or may be deleted after a certain period of time, and the history storage area has a certain amount of free space. It may be deleted if it falls below.

  On the other hand, the history of the identification name of the access point device to the computer communication network is stored in the route storage unit of the server device as the route traveled by the terminal device.

  That is, information for identifying a terminal device or a user thereof is associated with a history of access point device identification names, typically a route traveled by the terminal device represented by a sequence of identification names. Remembered.

  As information for identifying the terminal device, the MAC address of the network interface card that controls the communication function of the terminal device to the computer communication network, the serial number of the terminal device, the user name for using the service, and the like are used. be able to.

  Furthermore, the history receiving unit of the server device receives history information transmitted from any of the plurality of terminal devices.

  Typically, history information is transmitted to the server device via the Internet via an access point device from the terminal device to the computer communication network. The history information includes the history of the identification name detected by the terminal device as described above, but may include other information as will be described later.

  Furthermore, when any of the stored routes is similar to the history of the identification name specified in the received history information, the extraction unit of the server device extracts the terminal device that has moved along the similar route.

  As described above, the “stored route” is typically a history of identification names detected when another terminal device moves. Therefore, a typical case where the “stored route” and the “history of the identification name specified in the received history information” are similar to each other includes an identification name common to both It is. In this case, in the real world, the movement paths of both terminal devices cross each other. In addition, various aspects can be assumed for the concept of “similarity” as described later.

  And the information transmission part of a server apparatus transmits the relevant information which concerns on the extracted terminal device to the terminal device which transmitted the log | history of the said identification name.

  When a terminal device that has previously traveled a route similar to the travel route of the terminal device that has transmitted the history information is extracted, related information related to the extracted terminal device is transmitted to the terminal device that has transmitted the history information. The terminal device is “introduced”.

  Here, as the related information, as described later, the extracted terminal device user can be “a message written to another unspecified user moving in the same area”.

  Then, the update unit of the server device stores the history of the identification name specified in the received history information as a route traveled by the terminal device that transmitted the history information in the route storage unit, thereby Update.

  Through this process, the route of the terminal device that has transmitted the history of the identification name is registered, and thereafter, the route is subject to determination of similarity of movement routes of other terminal devices.

  The history of the identification name stored in the path storage unit may be deleted after a certain period of time, or may be deleted when related information is transmitted for the history, or the path If the free space in the storage area of the storage unit falls below a certain amount, it may be deleted.

  On the other hand, each information receiving part of a some terminal device receives the relevant information transmitted from a server apparatus, when communication with a server apparatus becomes possible via the access point apparatus of the detected identification name.

  Note that the related information cannot always be received, and the related information may not be transmitted from the server device when there is no other terminal device that has moved along a similar route.

  Further, the information display unit of the terminal device displays the received related information.

  As described above, when the related information is displayed, other terminal devices are introduced. If the related information is “a message written to another unspecified user moving in the same area”, the message will be displayed on the screen, and users who have a common topic Therefore, it is thought that user interaction will deepen further.

  According to the present invention, users who move in the same area can be introduced to each other, but when both users are in the vicinity in the real world, they are not introduced immediately, but when both users return home, It is possible to provide an introduction system in which unexpected troubles between users can be suppressed and privacy is taken into consideration.

  In the introduction system of the present invention, each of the plurality of terminal devices further includes an input receiving unit, and can be configured as follows.

  That is, the input reception unit of the terminal device receives a message input from the user.

  Typically, the message is “a message written to an unspecified other user moving in the same area” as described above.

  On the other hand, the history transmission unit of the terminal device further specifies a message for which input has been accepted, in the history information.

  Therefore, the history information transmitted to the server device includes the message in addition to the identification name history of the access point device.

  Furthermore, the update unit of the server device associates the message specified in the history information with the route traveled by the terminal device that transmitted the history information, and further stores the message in the route storage unit. A message associated with the similar route is specified as the related information related to the terminal device.

  By performing such processing, “a message written to another unspecified user moving in the same area” arrives at “a user who moved in the area”.

  According to the present invention, a message from a certain user to an unspecified user can be transmitted based on the fact that both users have moved in the same area, and messages similar to a bulletin board or bottle mail can be exchanged. Become.

  In the introduction system of the present invention, the history transmission unit of the terminal device further designates, in the history information, the time when each of the identification names is detected and the time when the message is accepted for input.

  Therefore, information on these times is also transmitted to the server device.

  The update unit of the server device divides the history of the identification name specified in the received history information every time the time when the identification name is detected exceeds a predetermined division threshold, and the divided identification name Is stored as a route traveled by the terminal device.

  For example, when “10 minutes” is adopted as the division threshold, if the time required for movement between access point devices exceeds 10 minutes, it is considered that the route is another route. The division threshold may be a fixed value, or may be adaptively changed with reference to history information transmitted from the terminal device.

  On the other hand, the update unit of the server device, when the time when the message is accepted is included in the time of the beginning and the end of the history of the divided identification name, the update unit of the divided identification name Store in association with any of the histories.

  Based on the time, it is determined in which route of the plurality of divided routes the message was input.

  According to the present invention, when the wireless communication becomes impossible, for example, by using transportation such as a train or a bus, or entering an underground mall or a building, it is considered that the movement route is divided there. By this, it becomes possible to divide the user's activity range into appropriate groups.

  In the introduction system of the present invention, the input reception unit of the terminal device can be configured to receive the input of the message while the identification name of the access point device is detected.

  In the present invention, whether or not to operate in the same area is determined based on the access point device, so that a message can be input only when the user is in the vicinity of the access point device.

  According to the present invention, by limiting the conditions under which a message can be input, the user is notified that the access point device exists in the vicinity and that exchanges with other users can occur based on the location. can do.

  In the introduction system of the present invention, the server device further includes a time storage unit, and can be configured as follows.

  That is, the estimated time required for movement between the identification names is stored in the time storage unit of the server device, and the update unit of the server device is included in the history of each of the divided identification names. Based on the time interval at which the adjacent identification names are detected, the estimated time required for the movement between the adjacent identification names stored in the time storage unit is further updated.

  If the user detects another access point device after detecting one access point device, the time required for movement between the two access point devices is determined by the detection time interval.

  Since various moving means are considered and the moving speed differs depending on the user, if the estimated value of the time required for moving between both access point devices is already stored in the time storage unit, the current moving time The estimated time required for the movement is typically obtained by overwriting or taking a weighted average with the current movement time.

  In addition, “time required for movement between the same access point devices” is “0”.

  On the other hand, the extraction unit, for each of the stored routes, between each of the identification names included in the route and each of the identification names included in the history of the identification name specified in the received history information The estimated time required for the movement is acquired from the time storage unit, and when the acquired estimated time is equal to or less than a predetermined similarity threshold, the route, the history of the identification name specified in the received history information, Are similar.

  That is, if the estimated time required for movement between access point devices included in the two movement paths is equal to or less than the similarity threshold, the same area is included even if the movement points of both users do not include the same access point apparatus. Is considered to have moved.

  The present invention is one of the preferred embodiments related to path similarity, and according to the present invention, even if the same access point device is not included in the user's moving path, users who have moved in areas close to each other are introduced. Will be able to.

  A server device according to another aspect of the present invention is a server device in the introduction system.

This is because the information processing apparatus 100 and a general computer are not greatly different in configuration and function. As described above, in the present application, a general computer and the information processing apparatus 100 will be described in the same manner.

  The information processing apparatus 100 described above corresponds to a so-called consumer game apparatus. However, as long as the apparatus has a function of communicating with a computer communication network, the terminal apparatus and server apparatus of the present invention can be realized. it can. Therefore, the present invention can be realized on various computers such as a mobile phone, a portable game device, a karaoke apparatus, and a general business computer.

  For example, a general computer, like the information processing apparatus 100, includes an image processing unit that includes a CPU, RAM, ROM, DVD-ROM drive, and NIC and has simpler functions than the information processing apparatus 100. In addition to having a hard disk as an external storage device, a flexible disk, a magneto-optical disk, a magnetic tape, and the like can be used. Further, not the controller 105 but a keyboard or a mouse is used as an input device.

The history storage unit 302 stores the history of the detected SSID. Further, the history transmission unit 303 transmits the history to the server device 202.

  The information receiving unit 304 receives various types of information from the server device 202, and the information display unit 305 displays the received information to the user.

  Under the control of the CPU 101 of the information processing apparatus 100, the NIC 109 that performs communication via the wireless LAN functions as the detection unit 301, and a storage medium such as the RAM 103 and the nonvolatile memory functions as the history storage unit 302, and the CPU 101 cooperates with NIC 109 to function as a history transmission unit 303 and an information reception unit 304. Under the control of the CPU 101, an image processing unit 107 and a monitor such as a liquid crystal display connected to the information processing unit It functions as the display unit 305.

  Furthermore, an input device that functions as the controller 105 such as a keyboard, a mouse, and a touch screen functions as the input receiving unit 306 and receives input of various messages from the user. The message input here is transmitted to the server device 202 as a part of the history, and further transmitted from the server device 202 to another terminal device 205.

  If this message is included in the information received by the information receiving unit 304, the information display unit 305 displays the message.

  FIG. 4 is a flowchart showing a control flow of terminal processing executed by the terminal device 205 according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

When the terminal process is started, the CPU 101 initializes a storage area such as the RAM 103 and the nonvolatile memory (step S401). Specifically, at the time of this initialization, the following processing is performed.
(1) Initialization of the history storage unit 302. When the history storage unit 302 is configured by the RAM 103, the storage area of the history storage unit 302 is cleared. When the history storage unit 302 is configured by a non-volatile memory, the storage content of the history storage unit 302 is checked for inconsistencies using a checksum or the like. If there is a mismatch, the stored contents are cleared. To do.
(2) Initialization of a message storage area for storing a message input by the user. When the message storage area is constituted by the RAM 103, it is cleared. When the message storage area is configured by a non-volatile memory, it is checked whether there is any inconsistency in the stored contents using a checksum or the like. If there is inconsistency, the stored contents are cleared.
(3) Various other initialization processes for the terminal device 205 to operate.

  Next, the CPU 101 controls the NIC 109 to determine whether or not a wireless beacon transmitted from the wireless LAN access point device 203 can be detected (step S402).

  When a wireless beacon cannot be detected (step S402; No), other various processes are executed as appropriate (step S403), and the process returns to step S402. Here, the various processes are typically arbitrary processes that are executed in a coroutine manner. For example, a process for displaying on the screen that a wireless beacon cannot be detected, or a process for waiting for a certain period of time. Etc. can be adopted.

  When the wireless beacon can be detected (step S402; Yes), the CPU 101 examines the detected wireless beacon and obtains the identification name of the access point of the wireless LAN that has emitted the wireless beacon (step S404). . Accordingly, the CPU 101 functions as the detection unit 301 in cooperation with the NIC 109.

  As described above, since the access point device 203 of the wireless LAN periodically emits a beacon, it is typical to use the SSID or MAC address of the access point device included in the beacon as an identification name. . It is technically possible for a third party who does not have a contract with the wireless LAN service provider to receive the beacon and examine the contents of the packet.

  Then, the CPU 101 inquires of the user whether or not to register a message (step S405). This message is a message destined for “any other user whose activity is in the neighborhood of the place where the user is currently located”. If no message is registered (step S405; No), the process proceeds to step S408.

  The inquiry is displayed on a monitor such as a liquid crystal display controlled by the image processing unit 107, and a user input is performed by operating various buttons, switches, and a touch panel of the controller 105.

  When there is an input for registration from the user (step S405; Yes), the CPU 101 controls the image processing unit 107 and the controller 105, the touch panel, the keyboard, the mouse, and the like, and allows the user to input a message. An input is accepted (step S406). Accordingly, these devices function as the input receiving unit 306.

  The message is a message addressed to "any other user whose activity is in the neighborhood of the user's current location". In addition to text messages, images drawn using the touch panel are used. It is also possible to do.

  Next, the CPU 101 stores the message input in step S406 in a message storage area composed of the RAM 103 and the nonvolatile memory in association with the current time (step S407). This storage is implemented in the form of an array or a queue. If there is no free space in the message storage area, the inquiry in step S405 may be skipped and the process may proceed to step S408, or the old message may be deleted.

  Then, the CPU 101 associates the identification name obtained in step S404 with the current time, and stores it in the history storage unit 302 configured by the RAM 103 or nonvolatile memory (step S408). The history storage unit 302 is typically implemented in the form of an array or a queue and is recorded whenever it is detected, but as long as the identification name of the same access point device 203 is detected, this is the case. This information may be compressed and information representing the detected time zone may be stored, or may be stored in the history storage unit 302 only when the detected identification name changes.

  Next, the CPU 101 controls the NIC 109 based on the information specified in the detected radio wave beacon, tries to associate the terminal device 205 with the access point device 203, and determines whether or not the connection to the Internet 204 is possible. (Step S409). If the association fails (step S409; No), the process proceeds to step S415.

  As described above, the association processing in the wireless LAN refers to the exchange of various information necessary for wireless communication and authentication between the terminal device 205 and the access point device 203 to manage the terminal device 205. This is a process of performing various registrations to be performed at 203.

  When the association is successful and the terminal device 205 is connectable to the Internet 204 (step S409; Yes), the terminal device 205 can communicate with the server device 202, so the CPU 101 stores it in the history storage unit 302. The message stored in the message storage area is added to the recorded history information and transmitted to the server device 202 via the NIC 109 (step S410). Therefore, the CPU 101 functions as the history transmission unit 303 in cooperation with the NIC 109.

  At this time, the serial number of the terminal device 205, the MAC address of the NIC 109, the user name using the terminal device 205, and the like are also transmitted to the server device 202 as the history information transmission source.

  In the present embodiment, the CPU 101 clears the history storage unit 302 and the message storage area (step S411). The clear timing may be erased after a certain period of time, or may be erased when the free space in the history storage area falls below a certain amount.

  Next, the CPU 101 checks whether the related information of the other terminal device 205 is transmitted from the server device 202 to itself (step S412). If not, the CPU 101 proceeds to step S415, and if it is transmitted ( Step S412; Yes), this is received (step S413). Therefore, the NIC 109 functions as the information receiving unit 304 under the control of the CPU 101.

  Here, the related information received from the server device 202 is typically a message input by another user in step S406 in the terminal processing in the other terminal device 205.

  Then, the other terminal device 205 is determined by the server device 202 to have moved along a route similar to the terminal device 205. Therefore, when there is no such other terminal device 205, the related information may not be received from the server device 202.

  Next, the CPU 101 controls the image processing unit 107 to display the received related information on a monitor such as a liquid crystal display (step S414). Therefore, the CPU 101 and the image processing unit 107 work together to function as the information display unit 305.

  In the present embodiment, since the related information is “a message written to another unspecified user moving in the same area”, the user of the terminal device 205 can use another terminal having a common topic. Since the introduction of the user of the device 205 is received, it is considered that the user's exchange is further deepened.

  Thereafter, other processes are appropriately executed (step S415), and the process returns to step S402. As processing executed in step S415, based on the related information displayed in step S414 or related information received in the past, a message not associated with the location of the access point device 203 is transmitted to another user. Processing can be considered.

  In the above-described embodiment, the related information is “a message written to another unspecified user moving in the same area”, but when the user is in the vicinity of the access point device 203, the input reception unit 306 Instead of the user entering a message via the user, the user registers his personal information, for example, information such as nickname, gender, hobby, age, etc., as related information, A simple form of notifying the time zone when the user has moved in the area is also conceivable.

  This is because it is considered that interesting information can be obtained for the user even if the existence of other users whose life is in a similar area can only be confirmed.

  In this case, it is effective for designating one of the users and individually sending a message similar to the e-mail in terms of user interaction. In this case, it is typical that a message is input by the input receiving unit 306, but the input of a message addressed to a specific individual is not limited to the vicinity of the access point device 203, It is desirable to be able to do it when the user desires.

(Configuration of server device)
FIG. 5 is a schematic diagram showing a schematic configuration of the server apparatus 202 according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  As shown in the figure, the server device 202 includes a path storage unit 501, a history reception unit 502, an extraction unit 503, an information transmission unit 504, and an update unit 505.

  Here, the history receiving unit 502 receives the SSID history transmitted by the terminal device 205 and messages accompanying the SSID, and the update unit 505 stores these history and messages in the path storage unit 501 as necessary. Then, the extraction unit 503 extracts messages and the like accompanying the history of the other terminal devices 205 that have moved along the route similar to the received SSID history from the route storage unit 501, and the information transmission unit 504 A message or the like is transmitted to the terminal device 205.

  Typically, the path storage unit 501 is realized by a hard disk or the like of the information processing apparatus 100. The CPU 101 and the NIC 109 work together to function as the history reception unit 502 and the information transmission unit 504, and the CPU 101 is a hard disk or the like. And function as an extraction unit 503 and an update unit 505. Details will be described below.

Here, the following information is associated and stored in the route storage unit 501 by the following service processing.
(1) Information for identifying a transmission source such as a manufacturing number, a MAC address, and a user name of the terminal device 205 that has transmitted history information.
(2) Information on the travel route. That is, a pair of the identification name of the access point device 203 detected by the terminal device 205 and the time when the identification name is detected.
(3) A message input at the terminal device 205 and a time when the message is input. Corresponding to one of the travel route information of (2) above.
(4) Estimated time required to move between identification names of the access point device 203. Logically, it is expressed as a matrix (two-dimensional array), but the matrix is a symmetric matrix, and the movement time is “unknown” between most of the identifiers. It is considered that the elements that can estimate the time become a sparse matrix limited to a part.
(5) A moving time division threshold for determining that the access point devices 203 are sufficiently separated from each other.
(6) A similarity threshold for travel time for determining that the access point devices 203 are sufficiently close to each other.

  The information (1) to (3) may be deleted after a certain period of time, or may be deleted when related information is transmitted for the history, or the path storage unit 501. If the free space in the storage area falls below a certain amount, the oldest one may be deleted.

  The information (4) may be deleted when the history information from the terminal device 205 regarding the movement between certain identification names is not transmitted for a certain period of time. If the free space in the storage area falls below a certain amount, it may be deleted.

  Further, the information of the above (5) and (6) may be determined as an appropriate constant, or may be adaptively updated according to the history information transmitted from the terminal device 205 as will be described later. good.

  FIG. 6 is a flowchart showing a control flow of a service method executed by the server apparatus 202 according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  First, the CPU 101 of the information processing apparatus 100 that implements the server apparatus 202 controls the NIC 109 to check whether a communication packet has arrived from the Internet 204 (step S601). If the communication packet has not arrived (step S601; No), other appropriate processing is typically executed in a coroutine manner (step S603), and the process returns to step S601.

  When the communication packet has arrived (step S601; Yes), the communication packet that has arrived is received (step S604), and it is checked whether the communication packet is history information transmitted from any of the terminal devices 205. (Step S605). If it is history information (step S605; Yes), the process proceeds to step S607. If it is not history information (step S605; No), processing corresponding to the type of the communication packet is executed (step S606), and the process returns to step S601.

  Therefore, the CPU 101 and the NIC 109 work together to function as the history receiving unit 502.

If it is determined in step S605 that the received communication packet is history information, the CPU 101 determines (1) the identification name of the access point device 203 and the detected time in the received history information. (2) Message By examining the time information entered and comparing the division threshold with the detection time, the user is divided into movement routes that are considered to have moved at a common sense speed, and the message is divided into the divided movement routes. Assigned to either one (step S607).

  FIG. 7 is an explanatory diagram showing how the identification name, message, and time information included in the history information are divided into movement route information. Hereinafter, a description will be given with reference to FIG.

  In this figure, the information included in the history information 701 is expressed in time series. On the time axis 702, the detected identification name 703 (represented by a circle in this figure) and the input message 704 are displayed. (Represented by square marks in this figure).

  If the interval between the identification names 703 adjacent on the time axis 702 is larger than the division threshold value 706, wireless communication is not possible at that time by using transportation such as a train or a bus or entering an underground mall or a building. It is considered impossible. Therefore, the movement route is divided there.

  When such division is performed, the movement route represents an activity range in which the user moves typically by low-speed movement means such as walking or bicycle. The divided movement route 705 is also a sequence of the identification name 703 in the order of detection time.

  In the terminal device 205 described above, the message 704 is input after the identification name 703 of a certain access point device 203 is detected, and when the input of the message 704 is completed, it is associated with the time at that time, and then detected. The time at that time is associated with the identification name 703. Therefore, each message 704 is typically included in the movement route 705 including the identification name 703 arranged immediately after that on the time axis.

  When one or more travel routes 705 are obtained in this way, for each of them, a travel route similar to the obtained travel route 705 is extracted from the travel routes already stored in the route storage unit 501. (Step S608).

As conditions for determining whether or not the movement routes are similar, the following can be selected as appropriate.
(1) When both moving routes include the same identification name 703. In the real world, the movement paths of both terminal devices 205 intersect.
(2) A case where the movement time between the identification names 703 included in both movement routes (so-called one-hop movement time) is equal to or less than a predetermined similarity threshold. In the real world, the movement paths of both terminal devices 205 do not intersect, but are close.
(3) Extending the above (2), the travel time (so-called n hops) when it is considered that the identifiers 703 included in both travel routes have moved to a predetermined number of other identifiers 703. ) Is less than or equal to a predetermined similarity threshold.
(4) In addition to the above (1) to (3), the time when both movement paths are detected is within a certain time. For example, a condition such as “move within one week” or “within one month” is added.

  In an aspect in which the estimated time required to move between the identification names of the access point devices 203 is not stored in the path storage unit 501, the above condition (1) is adopted, but the estimated time is the path storage unit 501. In the mode stored in (1), which of the above (1) to (3) is adopted can be appropriately changed depending on the use and the performance of the information processing apparatus 100 that implements the server apparatus 202.

  Next, information for identifying the other terminal device 205 that has moved along the movement route, such as the manufacturing number, MAC address, and user name of the terminal device 205 associated with the movement route extracted from the route storage unit 501 is extracted (step S1). S609). Further, if there is a message associated with the extracted movement route, the message is also extracted (step S610).

  Therefore, the CPU 101 functions as the extraction unit 503 in cooperation with a hard disk or the like.

  Then, the CPU 101 collects the information extracted in steps S609 and S610, and collects the information that has moved on the movement route 705 obtained in step S607 as related information of the other terminal device 205 that has moved on a similar route. The data is transmitted to the device 205 via the NIC 109 (step S611).

  Therefore, the CPU 101 functions as the information transmission unit 504 in cooperation with the NIC 109.

  Next, the CPU 101 correlates the movement path 705 obtained in step S607 and the message 704 associated with the movement path 705 with information for identifying the terminal device 205, and a path realized by a hard disk or the like. It is additionally stored in the storage unit 501 and updated (step S612), and the process returns to step S601. Therefore, the CPU 101 functions as the update unit 505 in cooperation with a hard disk or the like.

  Further, at this time, the division threshold or the similarity threshold may be updated.

For example, the following values can be adopted as the division threshold.
(1) A constant multiple of the average time interval of the identification name 703. The constant is a value greater than 1.
(2) A value obtained by adding a predetermined constant to the average of the time intervals of the identification name 703. The constant is a positive value such as “5 minutes”, “10 minutes”, “30 minutes”, or the like.

  When these values are adopted, the “average of time intervals so far” of the identification name 703 can be calculated backward from the value of the division threshold value stored in the current path storage unit 501.

  Therefore, in each of the movement paths 705 obtained in step S607, the time intervals of the adjacent identification names 703 are acquired, and the average of the acquired time intervals and the average of the time intervals so far are (weighted). On average, the latest estimate of travel time between adjacent access point devices 203 in the real world can be obtained.

  If this estimated value is the average of the time intervals of the identification name 703, a new division threshold can be obtained by the above calculation.

The new similarity threshold may be the above-mentioned “latest estimated value of the travel time between the access point devices 203”, or a constant and a calculation method may be defined similarly to the division threshold.
“Estimated value” ≦ “similarity threshold” ≦ “division threshold”
It is desirable to determine each constant so that the above relationship is established.
