Abstract

<P>PROBLEM TO BE SOLVED: To provide the relatively secure and useful place of information exchange in relatively simple system constitution. <P>SOLUTION: A plurality of terminals notify a server of location information at an instruction from a user or periodically. The server stores the location information and time information by associating them with each other for each user. In response to a request accompanied with the designation of the location and time of which the user has notified the server from the user, the server provides the same place of information exchange to the user who has made a request within the same location range and time range. For example, a user A who has been present in a certain location on a certain date notifies the server of the location, and performs registration(marking). Afterwards, the place of the information exchange with users B and X who have been present near the location in almost the same time on the same date, and have performed such similar marking, is provided on a network. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an information exchange service providing method, a communication system, and a server on a communication network for users of mobile terminals.

  Conventionally, navigation systems for vehicles and pedestrians are known as systems that use user position information. In addition, a technique has been proposed in which location information and time information of a user are transmitted to an information providing server, and the information providing server searches for recommended information (for example, a group of restaurants) based on the information and provides the user with the information (patent). Reference 1).

  Furthermore, the current location information of the registered user and personal information (age, gender, occupation, etc.) are stored in the server in association with each other, and other users who are in the vicinity of the current location information are received from the search requester. A service has also been proposed in which search is performed with conditions and information on a corresponding user is provided (Patent Document 2). For example, this can provide an opportunity for strangers who happen to be in the theme park to meet by chance.

On the other hand, in general, as a place of community using the Internet, a bulletin board (BBS) where any participant can write information, and an individual publishing any information such as a diary to obtain comments of others There are known user-participation-type information sharing places, such as a blog (Weblog) that allows users to participate, and social networks that are allowed to participate by introducing friends. Although these are different in form, each enables an individual to exchange information with others on a communication network.

  By the way, for example, when you encounter an unusual event on the go, you want to exchange information with a stranger who experienced the same event as a common topic after returning home There seem to be many people with desires.

  As described above, as a means of exchange with strangers, there is a service described in Patent Document 2, but exchange with a partner obtained as a result of search is performed via telephone or e-mail. , Mainly for meeting. Therefore, it is not suitable for the purpose of exchanging information between a plurality of unspecified persons on a common topic. The search is based on the real-time position at the current time point, and does not correspond to a search at a specific point in the past.

  In addition, on bulletin boards, blogs, social networks, etc., there may be times when other people who happened to see an event that they encountered at a certain point in the vicinity of the event may speak about the event. It is extremely difficult to find it from the site and the vast amount of information. On the other hand, even if you make a statement from yourself, you can hardly expect that someone who is in contact with the same event will see it by chance. Furthermore, a service that provides a community place on a network is usually accessible to an unspecified number of people, and is not necessarily a secure community. On the other hand, the system configuration is complicated in order to add user access restrictions, restrictions on disclosure information for users, and the like.

  The present invention has been made in such a background, and an object of the present invention is to provide an information exchange service providing method and communication system capable of providing a relatively secure and useful information exchange place with a relatively simple system configuration. , And to provide a server.

  An information exchange service providing method according to the present invention is an information exchange service providing method in which a server on a communication network provides an information exchange place where a plurality of users each having a mobile terminal can participate. A position within the same position range in response to a step of receiving position information of the user and storing it as marking information together with time information, and a request from the user with designation of the position and time of the user. Provides the same information exchange for users who make requests with specified time within the time range, and provides a different information exchange for requests with different location ranges and time ranges. And a step of performing.

  The server stores the information of the position where the user was actually from the plurality of users together with the time information at that time, and makes a request with the designation of the position within the same position range and the time within the time range. Provide users with the same information exchange. This provides a place for information exchange that is accessible only among those who share the same position range and time range.

  The communication system according to the present invention is a communication system realized by a portable terminal with a position detection function and a server that performs data communication between the portable terminal. In this system, each of the plurality of mobile terminals transmits at least position information of its own position as marking information to the server in accordance with an instruction from the user or periodically. The server receives at least the position information from each portable terminal, and stores the position information together with time information in association with the user. In addition, the server provides a site where the user of any mobile terminal can write remark information in association with the position and time marked by the user, and the other user has marked from another user on the site. In response to a search request specifying a position or time, search for the remark information of the user who performed marking corresponding to the position and time, present the remark information to the other user, On the other hand, writing comments is allowed.

  When the mobile terminal transmits to the server in real time, the time information may be confirmed by the mobile terminal and sent to the server, or the server may add the time information when receiving the location information.

  The server may include a map data storage unit and provide map data to a user when receiving a search request from the mobile terminal.

  More specifically, the server receives a search request from the other user, and a position within the vicinity position range of the position marked by the other user and a time range near the time associated with the position. The remark information of the user who performed marking for the time within is searched.

  The mobile terminal may sequentially accumulate the marking position and time, and may transmit a plurality of sets of positions and times accumulated at a predetermined time point to the server.

  A server according to the present invention is a server that performs data communication with a mobile terminal with a position detection function, and means for receiving at least position information as marking information from each of a plurality of mobile terminals, and each user of the mobile terminal Means for storing the positional information in association with time information, and means for providing a site where the server can write remark information associated with the position and time at which the user of any portable terminal performed marking In response to a search request specifying a position or time marked by the other user from another user on the site, search for remark information corresponding to the position and time, and send the remark to the other user. And a search means for presenting information.

  According to the present invention, a place where information is exchanged between users who share the same position range and time range using the two parameters of the position where the user was actually in the past and its time as search conditions. Can be provided. Such users are likely to share a common topic even if they are strangers, and are provided with useful communication opportunities.

  The system of the present invention handles personal information, but by providing access restriction that the user is actually at a certain time, a relatively secure information exchange place can be constructed with a relatively simple system configuration. . In other words, in order to participate in individual information exchange venues, the user must actually be in a certain place at a certain time, so the information seeker also needs to disclose self-information in a sense. It is possible to suppress acts such as fishing information for abuse. (A healthy open community can be built.)

  Furthermore, by making the storage of the history of time information and position information as a fixed period, it can be used for such purposes as providing a temporary information exchange place by sharing time and position.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. First, the configuration of the communication system of the present invention will be described, and then basic operations and specific operation examples will be described.

  FIG. 1 shows a schematic configuration of a communication system according to the present invention. This system includes a plurality of mobile terminals 11a and 11b having a data communication function and a position detection function, and a server 18 that communicates with the mobile terminals 11 (generically referred to as 11a and 11b). In this specification, the portable terminal device is referred to as a portable terminal or simply a terminal. The terminal 11 is connected to a mobile phone network (which may include a packet communication network) 15 via a base station 13. The cellular phone network 15 is connected to a communication network 17 such as the Internet via a gateway 16. The server 18 is connected to this communication network 17. The server 18 may be connected not to the communication network 17 but to the mobile phone network 15 side.

  The server 18 has a web server function, and stores and manages various data and exchanges information with the terminal 11. In this example, the server 18 includes a user data storage unit 21 that stores registered user information, a message data storage unit 22 that stores data of messages (threads and comments) described later, a marking data storage unit 23 that stores marking data, And it has the memory | storage part 20 containing the map data memory | storage part 24 etc. which stored map data.

  FIG. 2 is a block diagram illustrating an outline of the hardware configuration of the terminal 11. The terminal 11 includes an antenna 201, a transmission / reception processing unit 203, a modulation / demodulation processing unit 205, a data processing unit 207, a D / A converter 209, a speaker 210, an A / D converter 211, and a microphone 212 as elements unique to the mobile phone. Is provided. The terminal 11 also includes a controller 225 including a CPU, a ROM, and the like that control these elements, a memory 227 that is used as a work area and a temporary storage area for data by the controller 225, a liquid crystal display device that functions as a user interface, and the like. Display unit 220, an operation unit 223 corresponding to various operation keys, a clock unit 228 that performs time management (generation of date and time information, etc.), and a GPS reception unit 229 as position information detection means. The position information may be detected by a method using the position information of a base station of a mobile phone (including PHS) regardless of GPS. In this case, the position detection itself is performed outside the terminal. However, since the terminal requests the detection and receives the result, it is assumed that the terminal also has a position detection function in this case.

  FIG. 3 shows an outline of the hardware configuration of the server 18. The CPU 310 controls each part of the server by program control. The CPU 310 also includes a clock unit that performs time management (generation of date information, etc.). The memory 311 stores programs and data executed by the CPU 310. The memory 311 is connected to the CPU 310 via the bus 330. An input device 314 such as a keyboard, a display device 315 such as a CRT and a liquid crystal display, and an external storage device 316 such as a hard disk device are connected to the bus 330 via an interface 313. The external storage device 316 provides storage devices for various data storage units of the server 18. The bus 330 is connected to the communication network 17 via the communication unit 320.

  Next, exemplary contents of various data storage units used in the server 18 in the present embodiment will be described.

  FIG. 4 is a diagram showing an example of the contents of the user data storage unit 21. FIG. 4 (a) is a user management table 40 for registering information on users who use the service of the present invention in advance, and FIG. An image such as a photograph is shown. The user management table 40 includes a “user ID” that is user identification information for identifying individual users on the system, and a “user name” (may be a real name or a nickname) as a user name that can be easily recognized among users. , "Password" for each user to log in to a site on the Internet that provides this service, "image" consisting of a file name such as a photo image of each user, and "mail" as contact information for each user Register "Address". In addition, other personal information such as a telephone number may be included. However, passwords, images, email addresses, etc. are not essential registration information for this service. Although not shown in the figure, flag information may be provided that allows the user to set whether or not disclosure is permitted for each item of personal information.

  FIG. 5 is an explanatory diagram of the marking data stored in the marking data storage unit 23, and FIGS. 5A and 5B show different configuration examples. FIG. 5A is a diagram in which position information of each user is recorded as marking data 50a at periodic time intervals for each unit time (for example, 30 minutes). This corresponds to a case where each user terminal automatically detects its current position every unit time and reports it to the server 18 as its current position information. In the present specification, to register a pair of a certain date and time and the current position of the user (terminal) at that time by notifying the server is called marking. Marking may be performed automatically, manually according to a user instruction, or mixed. The automatic marking cycle may be different at each terminal. For example, the user may be able to variably set the cycle. In such a case, the marking data 50a in FIG. 5A may be missing specific user marking data depending on the date and time. Further, even when marking is performed for all users at the same cycle, marking data may be lost due to radio wave conditions such as terminal power-off or out of service area at that time. Furthermore, when the resolution of the time reported by the terminal is finer than the time interval collected by the server, the server may add the marking data to the time zone to which the time belongs.

  The marking data 50a in FIG. 5A is tabulated based on the date and time, but the marking data 50b in FIG. 5B is tabulated based on the user.

  Although not shown, it is also possible to aggregate marking data based on a combination of date and position. This records the user who performed the marking for each combination of date and time and position. The format of the marking data may be any of the above formats.

  The server does not need to permanently store the marking data, and may periodically delete past data. In other words, by making the storage of the history of time information and location information for a limited time, the community place provided by this service becomes a one-time, one-time-use, one-time-use, time-and-location share, and thereafter, users can mutually share each other. Because it becomes impossible to trace the information, it can be used with confidence.

  FIG. 6 is a diagram illustrating an example of the contents of the utterance data storage unit 22. FIG. 6A shows an utterance management table 60 for managing the identification information (thread ID) of existing threads and the identification information (comment ID) of existing comments for the date and time marked by the user for each user. Yes. FIG. 6B shows entity data of threads and comments. Although position information is always associated with each time, since the position information is always uniquely specified, only time information is used in this table. (For multiple markings of a user, the marking can be uniquely identified by the date and time, but the marking cannot be uniquely identified by the location.) There may be no thread for one marking, but the comment has a thread Can only exist. The number of comments is not necessarily one.

  Next, a basic operation example of the terminal and the server in the present embodiment will be described with reference to a flowchart.

  The main function of the terminal in this embodiment is marking processing. As described above, this can be manual or automatic. The system configuration may be manual only, automatic only, or a mixture of both.

  FIG. 7 shows an example of a procedure for manual marking processing of the terminal. The user of the terminal gives a marking instruction by performing a predetermined operation on the operation unit 223 (FIG. 2). Upon receiving this instruction (S11), the terminal operates the GPS receiving unit 229 to confirm the current position (S12). Further, the current date and time are confirmed by the clock unit 228 (S13). The confirmed current position and current date and time are transmitted to the server together with the user ID as position information and time information (marking data) (14).

  Here, an example is shown in which information is transmitted to the server at the time of marking. However, marking data may be stored locally in the terminal and transmitted to the server at a predetermined time. For example, marking data can be stored in the terminal within a certain period (for example, several hours to several tens of hours or one day), and the marking data accumulated during that period can be transmitted at once. It is.

  FIG. 8 shows an example of the procedure of the marking process (2) of the terminal in which automatic and manual are mixed. In this case, the terminal selects an automatic marking mode state (on / off) that determines whether or not automatic marking is performed in advance by the user. Further, as described above, the user may be able to variably set the automatic marking cycle, whether to report to the server in real time or collectively.

  When the automatic marking mode is on, the terminal determines whether the set period has arrived according to the timer function of the clock unit 228 (S22). If it is determined that the set cycle has arrived, the current position is confirmed (S24), and the current date and time are confirmed (S25).

  Even if the automatic marking mode is off in step S21, if there is a marking instruction by a user operation (S23), the process proceeds to step S24.

  The confirmed current position and current date and time are transmitted to the server together with the user ID as position information and time information (S26).

  In the case of FIG. 8 as well, reporting of marking data to the server can be performed in a batch process.

  Although not shown in the drawing, only automatic marking processing may be possible. The flowchart in this case is obtained by removing step 23 in FIG.

  FIG. 9 is a flowchart showing an example of the processing procedure of the server in the present embodiment. The main functions of the server in this embodiment include a user registration function, a marking reception function, a search function, a thread creation reception function, a thread read reception function, a comment write reception function, and the like.

  When the request received from the terminal by the server is a user registration request (S31), the user is registered in the user management table 40 as described in FIG. 4 (S32). If the request is a marking request, the received position information and time information are stored as a set in correspondence with the user specified by the user ID (S34). When the marking data is reported in real time, the date and time when the location information is received by the server may be used as the time information corresponding to the location information, instead of sending the time information from the terminal.

  When the request is a search request for speech (participation request) (S36), a search screen is presented to the user (S35). Web data such as a search screen is stored in advance in the external storage device 316 (FIG. 3), and is processed / edited as necessary. A search condition (for example, time information) by the user is received on the search screen (S37). A search process is executed according to the search conditions (S38). Next, the obtained search result is transmitted to the terminal (S39). This corresponds to opening a community corresponding to the time information marked by the user. In the community display screen, the corresponding user is specified, and if a thread is created, the title is displayed.

  When a thread creation request is received from the user in the opened community (S40), the user's thread creation is supported, and the created thread is received and stored in the thread data storage unit 22 (S41).

  When a thread read request specifying a specific thread is received from the user in the opened community (S42), the thread is transmitted to the terminal (and a comment if there is a corresponding comment) (S43).

  When there is a comment writing request from the user for this thread (S44), the comment writing is supported, and the created comment is received and stored in the comment data storage unit 22 (S45).

  Hereinafter, a specific operation example in the present embodiment will be described.

  As shown in FIG. 10, it is assumed that a plurality of users A, B, C, and X are in a positional relationship as illustrated at a certain date and time (or within a time range). In response to a search request from a certain user, for example, user A, a search is performed based on a position marked at a certain date and time (a position where the user was actually there). At this time, the presence / absence of another user who is at almost the same date and time in the position range 71A within a predetermined distance centered on the position where the user A was located is checked, not the exact same position. In the example of the figure, such other users are user B and user X. If user B is used as a reference, the other users in the position range 71B are user A and user C. Each user can enjoy the community for each set of date and position marked by the user. For this community, a thread of another user belonging to the same community is searched, and if it exists, the title of the thread is displayed (described later in FIG. 13).

  FIG. 11 shows an example of a series of time-series operations for marking and searching for the users A and B having the terminals A and B shown in FIG. Here, the case where each user performs marking manually is shown. User A performs markings a1, a2, and a3 at time points T1, T3, and T5. On the other hand, user B performs markings b1, b2, and b3 at time points T2, T4, and T5. In this example, each marking data is transmitted to the server in real time and stored in the server. The position of the user A at the time points T1, T3, and T5 is positions P1, P3, and P4, respectively. The positions of the user B at the time points T2, T4, and T5 are positions P2, P4, and P4, respectively. (User B is not moving during the period from time T4 to time T5.) Assume that at time T6, user B designates time T5 or position P4 and makes a search request for speech. In response to this, the server returns the search result to the terminal B. Assume that user B creates a thread there. Assume that at time T7, the user A designates the time T5 or the position P4 (marking a3) that he / she has marked, and makes a search search request. On the other hand, the server searches for and extracts the presence of another user who performed marking in the vicinity of the marking data. In this example, the user B who has performed the marking b3 within the range near the time T5 and the position P4 (in this example, the same date and time by chance) is extracted. The server detects that user B is writing a thread for this marking b3, and returns a search result including the title of this thread together with user B information to terminal A. User A reads the comment of user B's thread and writes a comment.

  FIG. 12 shows an example of a user interface at the time of speech search in the terminal. In this example, a date setting area 81 and a map display area 82 are provided on the screen. When the user designates the date and time on the terminal side, the corresponding position (if any) is determined, and the server searches for map data including this position and returns it to the terminal. A circular cursor 83 surrounding the position where the user was at that date and time is displayed. Since the date and time that can be actually specified is only the date and time when the user performed marking, the desired date and time may be selected by switching the marked date and time intermittently.

  In this example, a moving locus 84 is shown by connecting a series of positions marked by the user with a line. The cursor 83 may change the position by sequentially tracking the future side or the past side from that point in time according to the operation of the cursor key by the user, for example, so that a desired position can be selected. In that case, the date and time corresponding to the position may be searched, and the display of the date and time setting area 81 may be changed in conjunction. In this case, if there is a marking at the same position on the adjacent date and time, only the date and time may change due to the cursor operation.

  The display of the movement locus 84 is suitable when, for example, marking is performed periodically within a predetermined time (for example, one day). If the marking time points are separated for a certain time or longer due to manual marking or the like, the movement trajectory 84 is likely to be inaccurate, and the display thereof may be suppressed. Or you may make it suppress the display of the movement locus | trajectory 84, when the distance between the positions of adjacent marking is more than fixed.

  Since the marking data is stored in the server, it can be obtained from the server, but a copy thereof may be stored locally in the terminal as cache data.

  The search for the utterance is performed in accordance with the date and time and position selected in this way. This search is preferably done with a certain width in time and position. FIG. 13 shows a display example of a community (broadly defined community described later) corresponding to a certain time and position of the user B. This screen displays the number of users 91 who were nearby at that time, user images 92 and user names 93 as list information of those users, the number 94 of threads created in this community, and “create thread” "Button 95 is displayed. The example of FIG. 13 shows an example in which another user who performed marking at the same time exists in the vicinity but no one has created a thread yet. User B can create a thread by himself / herself by the instruction of the “create thread” button 95. The “Create Thread” button 95 is not actually a button shape, but is called a button because of its function for convenience. A link is set for this button, and a transition is made to a predetermined screen for thread creation (described later in FIG. 16).

  The user's contact information (for example, an e-mail address or a telephone number) is linked to the user name 93 or the image 92, and such contact information is displayed when instructed by a user operation. An e-mail creation screen for the user may be displayed.

  FIG. 14 shows an example of the result of user A searching for a statement with the same date and time information as the date and time of the example of FIG. In this case, there are two users (user B and user X) who are close to user A, and each of them creates a thread. That is, when another user included in the search result generates a community (including a community in a narrow sense to be described later) including himself / herself, information (thread title) written by the other user is displayed. . As can be seen from the drawing, titles 96 of these threads and a “read / write” button 97 are displayed on each screen. “Write” means writing a comment after reading the thread.

  Unlike the example of FIG. 13, if there is no thread even if the corresponding user exists as a result of the search, only the information “no corresponding thread” is displayed without displaying the user name 93 or the image 92. May be returned to the terminal.

  FIG. 15 shows a screen including a thread display area 100 and a writing area 107 that is displayed when the “read / write” button 97 of the first thread “Take a resident's card” in FIG. 14 is instructed. ing. The example of FIG. 15 shows an example in which the user B starts (creates) a thread and the user X who has read the thread enters a comment. As shown in the figure, a comment for one thread is displayed in association with the content of the thread's utterance (here, continued below). A comment that has been newly written in the “Write” field and has been written in accordance with an instruction of the “Write” button 109 is displayed continuously below the existing comment.

  In the example of FIG. 15, the “write” field of the comment is opened in advance, but may be opened after the user gives a write instruction.

  In the present embodiment, the information of other users can be understood to some extent even on the screen of FIG. 14, and this can be regarded as a community in a broad sense. However, it can be said that the thread display screen of FIG. 15 is a typical community (a community in a narrow sense) in terms of an information exchange place regarding a specific topic. In the community, information such as comments written by the user is shared with the users who are in the vicinity in time and position.

  FIG. 16 shows a thread creation screen 110 opened in response to an instruction of the “create thread” button 98 of FIG. This screen has a title input field 111, a comment input field 112, and a “Create” button 113. When creating a thread, the user inputs an arbitrary title in the title input field 111, writes an arbitrary comment in the comment input field 112, and then instructs the “Create” button 113 to complete the thread creation. The thread created in this way is displayed on the corresponding community screen (FIG. 14 and the like).

  In the present embodiment, the relationship is thread generator = community owner. Therefore, one thread is not included in a plurality of communities (in a narrow sense), and a community is generated for each thread. Therefore, selecting a thread selects a community.

  Access to a specific community is only possible if you are also marking yourself in the time and location neighborhood of the marking of the user who created the community, and if not, or if you are marking Access to the community is not granted if it is not close in time or location. (If the action history stored on the server is deleted, access to the community related to the deleted marking becomes impossible after such deletion is performed.)

  Therefore, this system cannot be used with the intention that a user who deviates from the access condition searches for an action history of another user.

  In addition to enjoying conversations on a common topic, the present invention can be used to encounter unusual events (accidents, incidents, happenings, etc.), participate in events, and listen to things that are of interest. Sometimes, marking can be done for the time being, and it can be used to search for detailed information and truth later, or to exchange opinions. For example, information sharing at events such as live events, happenings such as the emergence of rare animals, exchange of opinions about seasonal products that were sold specially, etc. can be considered. Or, if you lost something, you can follow your route to find out if someone has the information. In some cases, extremely important sighting information regarding a specific case may be obtained.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, the map search server provided with the map data storage unit and the server that handles the comment data are combined in the same server, but may be separate servers provided in different sites.

  The size of each of the time range and the position range may be specified or selected by the user.

  A mobile phone has been described as an example of the mobile terminal, but any mobile terminal can be used as long as it has a data communication function and a position detection function. The terminal that performs the marking may be different from the terminal that performs the search request. In this case, the terminal that makes the search request does not need to be portable and does not need to have a position detection function.

  The system configuration examples shown in FIGS. 1 to 3, the data configuration examples shown in FIGS. 4 to 6, the flowcharts shown in FIGS. 7 to 9, and the screen examples shown in FIGS. However, the present invention is not limited to them.

  When position information is recorded in correspondence with time as one's own action history, it is also possible to record (input) and manage not only the time and position but also events and memos associated with the time as the marking information.
