Description

  The present invention relates to a communication system in which people who participate in the same event such as travel can communicate with each other using a communication network such as the Internet.

  With the spread of the Internet in recent years, many systems have been devised that combine events held in real space and communication networks such as the Internet.

  For example, when an event is a trip, a travel agency opens a website on the Internet for travel, and the user uses the website to make reservations for transportation facilities, lodging, etc. and collect information on the travel destination. In addition to being able to make plans, it is also possible to view travel plans from a travel destination through a terminal connected to a communication network, and in addition, a system with a database that can store route guidance and travel records while traveling is also disclosed. (For example, Patent Document 1).

  However, the system of Patent Document 1 is a system devised for the purpose of supporting a travel plan and a trip itself, that is, an event held in a real space, and is an event held in a real space. It is not a system developed for communication between participants.

  With the recent diversification of hobbies and preferences, there are increasing cases of individuals participating in events without participating in events. For example, in the case of travel, there is an increasing number of individuals traveling without participating in a package tour planned by a travel agency, and a system that enables communication between persons having the same travel purpose is required.

As a system in which people who have actually seen, heard and experienced the same thing in the real world exchange opinions in real time, for example, in Patent Document 2, based on information that senses a limited space in the real world, A system for constructing a virtual communication space in which people in the space exchange opinions and opinions in real time is disclosed.
JP 2003-150680 A WO00 / 076154

However, in the system disclosed in Patent Document 2, indeed, but in practice each other hear and see-experienced person to the same thing in the real world can be realized a system in which mutually exchange ideas in real time, described below problems is there.

  The first problem is that since a means for constructing a virtual communication space is required, a means for constructing a virtual communication space is required every time a virtual communication space is constructed.

  In Patent Document 2, a virtual communication space is constructed by a communication medium that provides a communication channel that enables communication in a limited space in the real world, and means for realizing the communication medium every time a virtual communication space is constructed. I need it. For example, when the communication medium is wireless communication, the virtual communication providing means for constructing the virtual communication space has a wireless communication antenna, and an area that can be transmitted and received by the wireless communication antenna is the virtual communication space. Therefore, when constructing a plurality of virtual communication spaces, it is necessary to provide a plurality of virtual communication providing means equipped with wireless communication antennas.

  In order to construct a plurality of virtual communication spaces, the provision of a plurality of virtual communication providing means has a problem of increasing the cost of constructing a system. For example, when the virtual communication space is realized by wireless communication and the virtual communication space is widened, the wireless communication antenna has a high output and cannot be easily set.

  The second problem is that since the virtual communication space is realized by communication media, it is not easy to change the size of the virtual communication space once set, and it is not easy to set the virtual communication space in detail. Disappear.

  For example, when the virtual communication space is realized by wireless communication, changing the size of the virtual communication space adjusts the output of the wireless communication antenna. The work of adjusting the output of the wireless communication antenna is not only difficult, but when the output of the wireless communication antenna is increased, the size of the virtual communication space may not be increased to a desired size due to limitations of the Radio Law.

  Therefore, in view of the above-mentioned problems, the present invention does not require special communication media, and those who participate in an event held in a real space such as a trip and have the same purpose hold the event. It is an object of the present invention to provide a communication system, an event server, and a method capable of performing communication within an area.

It verifies that there is an event participant 90 in an area where the event is held in real space.

In FIG. 5, the event area has a circular shape 142, but the event area may have any shape such as an ellipse, a quadrangle, or a triangle. In the embodiment , the event geographic information database 124 stores information necessary for calculating the shape of the event area. However, the geographic information for identifying the event area is stored in the event geographic information database 124. May be. For example, if the event area has a quadrangular shape, the event server 120 can identify the quadrangular event area without calculating it by storing the latitude and longitude of the four corners of the quadrilateral in the event geographic information database 124.

Here, the community formation unit 127 that is provided to the event server 120 will be described procedure for forming the events of the community. The procedure for forming a community includes an event application process in which an event participant accesses the event server 120 and applies for participation in the event, and a community formation process in which the event server 120 forms a community.

(Event application process)
First, an event application process will be described in which a person who wishes to participate in an event applies for participation in the event, and acquires the right information 111 which means that the right to participate in the event is acquired from the event server 120. FIG. 6 is a flowchart showing the procedure of the event application process. The first step of the event application process is a step of accessing the event server 120 using the mobile phone 110 possessed by a person who applies for participation in the event (hereinafter referred to as an event applicant) (step S100).

  When the event server 120 is accessed from the mobile phone 110 to signify an event, the event server 120 uses the information stored in the event information database 121 to create event list information. Is provided to the mobile phone 110 (step S110).

Event applicant is, for example, by referring to the information about the event, sign up to participate in the event you want. When applying for participation in an event, the event applicant's personal information (eg name and home phone number), the mobile phone number of the mobile phone held by the event applicant, and the participation fee if an event fee is set for the event Information such as information (for example, credit card number) necessary for the billing process is transmitted to the event server 120, and the event server 120 temporarily stores the transmitted information in the event server 120 (step S120).

  The event server 120 confirms the information transmitted from the event applicant and temporarily stores it when necessary information is available (if there is a billing process, after performing the billing process). Information about the event applicant (for example, personal information of the event applicant) is registered in the event registrant database 123 as personal information 123a or the like (step S130). The event applicant becomes an event participant by being registered in the event registrant database 123.

  When the event server 120 registers an event applicant in the event registrant database 123, the event server 120 uses the right information 111, which is information for authenticating the event applicant, and the authentication information 123b as information for authenticating the right information 111. Generate. The generated right information 111 is transmitted to the mobile phone 110, and the transmitted right information 111 is stored in the storage unit 115 of the mobile phone 110. The generated authentication information 123b is stored in the event registrant database 123 together with information transmitted from the event applicant (step S140).

In the above example, the mobile phone 110 accesses the event server 120 and applies for participation in the event. However, if the mobile phone 110 supports an external memory (for example, a memory card), the event applicant It is also possible to apply for an event by accessing the event server 120 from a personal computer possessed by the personal computer. In this case, the event applicant stores the right information 111 transmitted from the event server 120 in the external memory , and inserts the external memory into the mobile phone 110 when participating in the event. Further, the event applicant may apply for participation in the event using a personal computer, and the right information 111 may be transmitted to the mobile phone 110 possessed by the event applicant .

(Community formation process)
The community formation process is a process of virtually forming a community between event participants participating in the same event, and community participants belonging to the same community can communicate with each other using the communication means 130. . FIG. 7 is a flowchart showing the procedure of the community formation process.

  The first step of the community formation process is a step in which an event participant accesses the event server 120 using the mobile phone 110 and desires to participate in the community. When wishing to participate in the community, the mobile phone 110 acquires the current location information using the location detection means 112, and the acquired current location information and the right information 111 stored in the storage unit 115 of the mobile phone Is transmitted to at least the event server 120 (step S200).

  When there is an access from the mobile phone 110 that wishes to participate in the community, the event server 120 identifies information (event number 111a, event name 111b, and period information 111c) included in the right information 111 transmitted from the mobile phone 110. ) Matches the information (event number 122a, event name 122b, and period information 122c) stored in the event information database 121 (step S210).

Next, the right information authenticating means 126 provided in the community forming means 127 acquires the authentication information 123b corresponding to the event participant number 111d included in the right information 111 from the event registrant database 123 (step S220). When the event server 120 acquires the authentication information 123b, the event server 120 authenticates the famous information 111e of the right information 111 transmitted from the mobile phone 110 using the acquired authentication information 123b (step S230). If authentication is successful, processing is continued . If authentication fails, processing is stopped.

  Next, the community forming unit 127 confirms that the date and time when access was made from the mobile phone 110 is included in the period indicated by the period information 122c corresponding to the event number acquired from the event information 122 (step S240). If the date and time accessed from the mobile phone 110 is included in the period indicated by the period information 122c, the process is continued, and if not included, the process is stopped.

Next, the community forming unit 127 acquires event geographic information 125 corresponding to the acquired event number from the event geographic information database 124, and calculates an event area. In the embodiment , a circular event area is calculated using the event geographic information 125 acquired from the event geographic information database 124 (step S250).

When the event area is calculated, the community forming unit 127 confirms that the position information transmitted from the mobile phone 110 is included in the calculated event area (step S260). If the position information is included in the calculated event area, the process is continued. If the position information is not included in the calculated event area, the process is stopped.

In the next step, the community formation means 127 permits an event participant who has access to participate in the community to join the community, and the community formation means 127 adds the event participant to the community list 128 and The location information transmitted from the telephone 110 is stored as community participant location information 129 (step S270).

  Thus, in order to participate in the event community, the validity of the right information 111 is verified, and it is necessary to be in the event area in the real space during the event holding period. The event participants registered in the community become community participants, and can communicate with other community participants belonging to the same community by the communication means 130.

  In addition, when there is access from other mobile phones 110 to participate in the event community, or after a certain period of time has elapsed after the community tea list 128 is created or updated, the event server 120 displays all of the events described in the community list 128. The location information of the community participant is acquired from the mobile phone 110, and the community list 128 is updated by repeating the steps after step S250.

As shown in FIG. 2, the community forming unit 127 of the event server 120 stores the communication condition 131 transmitted from the community participant in order to extract the community participant who can communicate with the community participant who desires communication. The community forming means 127 customizes the community list 128 based on the communication condition 131 of the community participant and transmits it to the community participant .

Here, the communication condition 131 is a condition for restricting the partner with whom the community participant communicates, and includes a distance condition that depends on the distance to the communication partner and a profile condition that depends on the profile of the communication partner. It is out.

  The communication means 130 provided in the event server 120 is a community Peer-to-peer (P2P, Person to P) between mobile phones 110 owned by participants erson) means for exchanging peer-to-peer text information. Or a means for making a real-time voice call using the Internet 182 is suitable. The Community participants are listed in the customized community list 128. By selecting other community participants in the browser 113 of the mobile phone 110 , You can exchange peer-to-peer messages with selected community participants The

Further, the browser 113 provided in the mobile phone 110, communication condition setting means 113a which can set the communication conditions 13 1 optionally event participants is provided. Communication condition setting means 113a is implemented by an application stored in the storage unit 11 1a of the mobile phone 110.

As shown in FIG. 2, when an event participant wishes to join the community, set the communication conditions 131 by using the communication condition setting means 113a provided in the browser 113, an event server from the mobile telephone 110 A communication condition 131 is transmitted to 120 . The community forming unit 127 provided in the event server 120 verifies the event participant and then stores the transmitted communication condition 131 in association with the communication participant. The community formation unit 127, and customized based on communication conditions 131 that is transmitted to the community list 128, transmits a community list 128 customized to the community participant.

Since the community list 128 transmitted to the community participant is customized by the communication condition 131 of the community participant, the community participant communicates only with other community participants that meet the set communication condition 131. be able to.

(Customize community list based on distance conditions)
From here, customization of the community list 128 based on the distance condition will be described. The distance condition of the communication condition 131 is a condition in which the community participant limits the communication partner based on the distance from the current position of the community participant. For example, you may want to communicate only with other community participants who are within a certain distance from the community participant, or you do not want to communicate with other community participants who are within a certain distance from the community participant. means.

The customization of the community list 128 based on the distance condition is performed in two steps. The first procedure, based on the distance condition of the community participant that sends a community list 128, is a procedure for extracting a community participant community forming means 127 matches the distance condition from the community list 128 which is stored .

The community participant sets the distance condition and transmits the set distance condition to the event server 120 . Provided in the event the server 120 community forming unit 127, and a location information of the community participant to send position information and community list 128 community participants are stored in the community formation unit 127, the same as the community participants calculates the distance to the other community participants belonging to the community, by comparing the distance conditions, community forming means 127 community participant extracts the person to perform the communication from the community list 128.

In the second procedure, it is determined whether the community participant sending the community list 128 is suitable for the distance condition of the community participant extracted in the first procedure, and the non-conforming distance condition is set. This is a procedure for deleting community participants from the community participants extracted in the first procedure.

By confirming the distance condition of the community participant who transmits the community list 128 in the first procedure described above, and confirming the distance condition of the community participant extracted in the first procedure in the second procedure. The persons who communicate with each other satisfy the distance conditions.

  FIG. 8 is a diagram for explaining the first procedure described above. FIG. 8A is a diagram showing an event area and the positions of community participants in the event area. In FIG. 8A, a point 241 indicated in the event area 240 indicates the current position of the community participant A, and in the event area 240, two communities of community participants B and C in addition to the community participant A are included. Suppose there are participants. Point 242 is the current location of community participant B, and point 243 is the current location of community participant C. In FIG. 8A, it is assumed that the community participant A defines a distance condition for communicating with other community participants in the circular shape 241a having the radius R.

FIG. 8B is a diagram for explaining the community list 128 in the state of FIG. In the state of FIG. 8A, the community list 128 stored in the community forming unit 127 is FIG. 8B. When the community formation means 127 transmits the community list 128 to the community participant A, the community formation means 127 uses the community participant location information 129 stored in the community formation means 127 to use the community participant A and other community participants. And the other community participants that match the distance condition of the community participant A are extracted from the community list 128 . Community list 128 extracted another community participant that matches the distance condition of the community participant A from community list 128 is shown in FIG 8 (c). As shown in FIG. 8C, according to the distance condition of the community participant A, the community participant who can communicate with the community participant A has a radius R from the current position (point 241) of the community participant A. Only the community participant B in the circular shape 241a.

FIG. 8D shows an example in which the distance condition of the community participant A is set to be outside the circular shape 241a having the radius R. In FIG. 8A, since the only other community participant outside the circular shape 241a having the radius R from the position of the community participant A is the community participant C at the point 243, the distance condition of the community participant A is satisfied. Accordingly, the community participant who can communicate with the community participant A is the community participant C.

  FIG. 9 is a diagram for explaining the second procedure described above. FIG. 9A illustrates the distance conditions of the community participants B and C in addition to FIG. 8A. 9A, the distance condition of the community participant A is outside the circular shape 241a with the radius R, the distance condition of the community participant B is outside the circular shape 242a with the radius R1, and the distance condition of the community participant C is the radius condition. The outside of the circle 243a of R2 is set.

  FIG. 9B is a diagram showing a situation in which community participants are extracted according to the first procedure based on the distance conditions of the community participants A, B, and C, respectively. In FIG. 9B, “◯” indicates the extracted community participant, and “×” indicates the community participant that has not been extracted. For example, based on the distance condition of the community participant A, as described above, the community participant extracted in the first procedure is only the community participant C.

  In the second procedure, it is confirmed whether the community participant A matches the distance condition of the community participant C. As can be seen from FIG. 9B, since the community participant A meets the distance condition of the community participant C, the community participant described in the community list 128 transmitted to the community participant A is Only community participant C.

Considering the community list 128 to be sent to the community participant B, as can be seen from FIG. 9B, the community participation extracted in the first procedure based on the distance condition of the community participant B. Are community participant A and community participant C. However, in the second procedure, since the community participant B does not meet the distance condition of the community participant A, the community participant A is deleted from the community list 128 transmitted to the community participant B. In the community participant C, since the community participant B meets the distance condition of the community participant C, the community participant C is described in the community list 128 transmitted to the community participant B.

(Customize community list based on profile conditions)
From here, customization of the community list based on profile conditions set by community participants will be described. The profile condition is a condition for restricting the communication partner based on the profile such as the age or sex of the community participant.

The communication partner is extracted by comparing the personal information item of the event participant stored in the event registrant database 123 with the profile condition. In the customization of the community list 128 based on the profile condition of the community participant, similarly to the customization of the community list 128 based on the distance condition, community participants that match the profile condition of the community participant who sends the community list 128 are extracted. After confirming whether the community participant who transmits the community list 128 matches the extracted profile condition of the community participant, the customized community list 128 is transmitted.

FIG. 10 is a diagram for explaining customization of the community list 128 based on profile conditions. FIG. 10A is a diagram showing an example of items of personal information of event participants stored in the event registrant database 123 . As shown in FIG. 10A, the event registrant database 123 stores the age and gender of event participants as items of personal information. The personal information shown in FIG. 10A is the personal information of each of the community participants A to C in FIG. 9A.

  FIG. 10B is a diagram showing the profile conditions of the community participants A to C, respectively. In the profile condition shown in FIG. 10B, a request for each item of personal information of a communication partner is described. For example, the item regarding the age of the profile condition of the community participant A is “Free”, which means that no restriction is set regarding the age. Moreover, the item regarding the gender of the profile condition is “female”, and regarding the gender, it means that “female” is requested as a communication partner. When extracting community participants based on profile conditions, each item of the profile conditions is extracted by AND (AND logic). That is, community participants having personal information that matches all the items of age and gender in the profile condition are extracted.

  FIG. 10C is a diagram for explaining a situation in which community participants are extracted based on the profile conditions of the community participants A to C, respectively. In FIG. 10C, “◯” indicates the extracted community participant, and “×” indicates the community participant that is not extracted. For example, based on the profile condition of community participant A, the age and sex of community participant B are extracted because they match the profile condition of community participant A. The age of community participant C matches the profile condition of community participant A, but the gender is not extracted because it does not match the profile condition of community participant A.

  The operation of customizing the community list based on the profile condition will be described using the community participant C as an example. First, community participants are extracted based on the profile conditions of community participant C. As shown in FIG. 10 (c), community participants that match the profile condition of community participant C are community participants A and B. Next, it is confirmed whether or not the community participant C matches the extracted request profile of the community participant. As shown in FIG. 10 (c), community participant C does not meet the profile condition of community participant A, and community participant C meets the profile condition of community participant B. Community participant B is the only community participant described in the community list customized based on the profile conditions to be transmitted to person C.

In this way, by customizing the community list according to the communication conditions set by the community participants, it is possible to communicate only with the community participants that match the communication conditions of the community participants. For example, in FIG. 9, only the community participant C matches the distance condition of the community participant A, but in FIG. 10, the community participant C does not meet the profile condition of the community participant A. . Therefore, in FIG. 9A, no community participant meets all the communication conditions 131 (distance condition, profile condition) of the community participant A. Further, the only community participant that matches all the communication conditions (distance condition, profile condition) of the community participant C is the community participant B.

In addition, when there is a condition that depends on the passage of time in the communication condition 131 , the community forming means 127 updates the created community list 128 at regular intervals and customizes it based on the communication condition 131 of each community participant. A community list 128 is sent to each community participant.

For example, when the distance condition is set in the communication condition 131 , the location information of the community participant changes with the passage of time. Therefore, when the community list 128 is updated, the community forming unit 127 will participate in the community at the time of the update. based on the position information of the user, calculates the distance between the community participant to customize community list 128 is updated based on the communication conditions 131 Fukumaru community participant community list 128 is updated is set, to send a community list that is customized to each of the community over the participants. The community participant can perform a peer-to-peer message exchange with the selected community participant by selecting another community participant described in the customized community list 128 with the browser 113 of the mobile phone 110. it can.

From here, the community formation means 127 of the event server 120 is communicated. A procedure for customizing the application list 128 will be described. Figure 11 shows communication Explains the procedure for customizing the communication list 128 based on the communication condition 131 It is a flowchart for clarifying.

The first step in the procedure for customizing the community list 128 is a step in which the communication condition 131 is transmitted from the community participant (step S300).

The next step is a step of extracting other community participants that match the communication condition 131 transmitted from the community participant who transmits the community list 128 (step S310). In this step, the distance to other community participants is calculated based on at least the distance condition of the communication condition 131, and community participants whose calculated distance matches the distance condition are extracted. Step S310 is the first procedure in the customization of the community list 128 described above.

The next step is a step of confirming whether the community participant who transmits the community list 128 matches the communication condition 131 of the community participant extracted in step S310 (step S320). If the distance condition of the communication condition 131 is followed, the community participant who has set the distance condition that does not match the distance calculated in step S310 is deleted from the community participants extracted in step S310. Step S320 is the second procedure in customizing the community list 128 .

The next step is a step of transmitting the community list 128 describing only the community participants extracted in step S310 and not deleted in step S320 (step S330). The community participant can perform a peer-to-peer message exchange with the selected community participant by selecting another community participant described in the customized community list 128 using the browser 113 of the mobile phone 110. it can.
