Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
<Embodiment>
<Overview>
FIG. 1 is a system diagram showing a system configuration of a communication system.

  As shown in FIG. 1, the communication system includes a server 100, and the server 100 is connected to a user terminal 200 and a user terminal 300 via a network 500. Here, the user terminal 200 and the user terminal 300 enjoy the same service provided by the server 100. The service includes a function of associating users and registering them as friends.

  Here, it is assumed that the user 200u of the user terminal 200 wants to become a friend after seeing the user 300u of the user terminal 300. Then, the user 200 u inputs the appearance information of the user 300 u to the user terminal 200 and transmits the appearance information to the server 100. At this time, the user terminal 200 transmits the position information of the user terminal 200 together with the appearance information.

  Based on the appearance information received from the user terminal 200, the server 100 searches whether the user corresponding to the appearance information has registered for service. Here, it is assumed that a plurality of users including the user 300u are searched. When the server 100 finds a corresponding user, the server 100 acquires position information (here, the user terminal 300) of the user terminal of the user. Then, it is determined whether or not the position information of the user terminal 300 is within a predetermined range from the position information of the user terminal 200. In addition, for other searched users, it is determined whether or not the position information is within a predetermined range.

  If the server 100 determines that the user terminal is within the predetermined range, the server 100 transmits the user information of the user terminal 300 to the user terminal 200. Thereby, the user terminal 200 can make an association application to the user terminal 300. Here, the association application refers to transmitting an application for associating users to the server in order to facilitate the exchange of messages between users on the service, for example, friend request, friend It is called application or follow-up. Hereinafter, this is referred to as a friend addition request. The server 100 that has received the friend addition request for the user of the user terminal 300 from the user terminal 200 stores the user of the user terminal 200 and the user of the user terminal 300 in association with each other as friends. This makes it possible to register friends without knowing the other party's information on the service.

  In FIG. 1, only two user terminals 200 and 300 are shown for the sake of simplicity of explanation, but even more terminals may exist on the service. Needless to say, it is good.

The position of the user is “(X3, Y3)”, “A13810.jpg” is associated with the appearance photograph, and “B13810.jpg” is associated with the belongings photograph.

  By associating various types of information that can specify the appearance of the user as the user information 400, a desired user can be specified on the service provided by the server 100.

<Operation>
An operation of the communication system according to the present embodiment will be described.

After explaining the exchange between the user terminals 200 and 300 and the server 100 using FIG. 5, the operation of the user terminal will be explained using FIG. 6, and the operation of the server 100 will be explained using FIG.
FIG. 5 is a sequence diagram showing exchanges between the user terminal 200 and the server 100.

  The user terminal 200 includes a user information request including user appearance information input by the user, that is, appearance information of a desired user (here, the user 300 u possessing the user terminal 300) and position information of the user terminal 200. Is transmitted to the server 100 (step S501).

  When receiving the user information request, the server 100 estimates and specifies the user desired by the user 200u of the user terminal 200 based on the appearance information included in the user information request (step S502).

The server 100 transmits the information on the user specified in step S502 (information on the user 300u of the user terminal 300) to the user terminal 200 (step S503).
The user terminal 200 that has received the user information from the server 100 displays the received user information (step S504).

The user 200u sees the displayed user information and executes the friend's friend addition input. Then, the user terminal 200 transmits a friend addition request to the server 100 (step S505). Thereby, in the server 100, the user ID of the user terminal 200 and the user ID of the user terminal 300 are associated as friends.
The above is the exchange with the server 100 when the user terminal requests other users' information from the server.
Next, the operation of the user terminal is shown. Here, although described as the operation of the user terminal 200, the operation is also common to the user terminal 300.
FIG. 6 is a flowchart showing the operation of the user terminal 200.
The user 200u performs an input requesting the information of the user 300u from the input unit 210 (step S601).

The user 200u inputs the appearance information of the user 300u using the input unit 210 in the user terminal 200. Thereby, the user terminal 200 acquires the appearance information of the user desired by the user 200u (step S602).
Next, the position information acquisition unit 253 of the user terminal 200 acquires the position information of the own device using GPS (step S603).

The information processing unit 251 of the user terminal 200 transmits a user information request including the appearance information acquired in step S602 and the position information acquired in step S603 to the server 100 via the communication unit 220 (step S604). .
The communication unit 220 receives information transmitted from the server 100 in response to a user information request transmitted by the user terminal 200.

If the received information is the requested user information (YES in step S605), the received user information is displayed. Then, in accordance with the received user information, the user 200u inputs a friend addition request to the input unit 210. In response to the input, the information processing unit 251 of the user terminal 200 transmits a user friend addition request indicated by the user information to the server 100 (step S606).
Thereby, in the server 100, the user 200u and the user 300u are associated as friends.
The above is the operation of the user terminal 200 showing the method of adding friends when the user information on the service is not known.
Finally, the operation of the server 100 is shown.
FIG. 7 is a flowchart showing the operation of the server 100.

  As shown in FIG. 7, the communication unit 110 of the server 100 sends a user information request including position information indicating the current location of the user terminal and user appearance information related to user information desired by the user of the user terminal. Receive (step S701). The communication unit 110 transmits the received user information request to the estimation unit 131.

  The estimation unit 131 extracts appearance information included in the transmitted user information request. In addition, the estimation unit 131 accesses user information 400 stored in the storage unit 120. Then, the estimation unit 131 searches the user information 400 to determine whether there is a user who has information that matches the extracted appearance information (step S702). Here, when the appearance information includes a plurality of pieces of information, the estimation unit 131 searches for a user that matches all of them.

  If a matching user can be searched (YES in step S703), the estimation unit 131 transmits information about the searched user to the position information acquisition unit 132. Then, the position information acquisition unit 132 acquires the position information of the user terminal possessed by the transmitted user (step S704). Specifically, the position information acquisition unit 132 requests and acquires the position information directly from the user terminal when the transmitted user permits the search of the position information, and when the user does not permit the position information search. The position information registered in the user information 400 is acquired. Then, the position information acquisition unit 132 transmits the acquired position information to the specifying unit 133. In addition, although it is set as the structure which sets beforehand whether the request | requirement of the positional information from the server 100 is permitted here, this is the server 100 to the user terminal of the user which the estimation part 131 estimated at this timing. It is good also as a structure which transmits the information which asks permission of acquisition of position information, and acquires permission from a user.

  When the position information of the user estimated by the estimation unit 131 is transmitted from the position information acquisition unit 132, the specifying unit 133 determines whether there is a user within a predetermined range from the position information of the user terminal that transmitted the user information request. Determine whether. Specifically, the specifying unit 133 calculates the distance between the transmitted position information and the position information of the user terminal that transmitted the user information request. Then, it is determined whether or not the distance is within a predetermined distance (step S705).

  If there is information transmitted within the predetermined range (YES in step S705), the specifying unit 133 specifies a user corresponding to the position information determined to exist within the predetermined range (step S706). ). The identification unit 133 transmits the identified user information to the notification unit 134.

  When the user information is transmitted, the notification unit 134 transmits the transmitted user information to the user terminal that transmitted the user information request via the communication unit 110 (step S707), and the process ends.

When the estimation unit 131 cannot search for a user who matches the appearance information (NO in step S703), or when the specifying unit 133 determines that there is no position information transmitted within the predetermined range from the position information of the user terminal. (NO in step S705), the notification unit 134 transmits information indicating “not applicable” to the user terminal that transmitted the user information request via the communication unit 110 (step S708), and the process ends.
The above is the operation of the server 100 related to friend addition.
<Summary>

  According to the communication system according to the present embodiment, it is possible to provide information about a desired user by transmitting its own position information and the appearance information of the other party to the server. Therefore, even if the user does not recognize the information of the other party on the service, the friend registration with the other party or communication can be performed.

<Modification>
Although one embodiment of the invention according to the present invention has been described in the above embodiment, it goes without saying that the idea according to the present invention is not limited thereto. Hereinafter, various modifications included as the idea of the present invention will be described.

  (1) In the embodiment described above, the user terminal 200 is configured to be able to acquire user information that matches the transmitted appearance information from the server 100. Here, before transmitting user information to the user terminal 200, the server 100 may request permission from the user corresponding to the user information.

  That is, after the specifying unit 133 specifies the user information, the user information of the user who owns the user terminal 200 is transmitted to the user terminal corresponding to the specified user information (the user terminal 300 in the above embodiment), The user of the user terminal 200 is notified that the user information of the user of the user terminal 300 is desired. The user of the user terminal 300 who sees the notification responds with permission or rejection to it. When the response of permission is obtained, the server 100 transmits the user information of the user terminal 300 to the user terminal 200, and when the response of rejection is obtained, the server 100 notifies the user terminal 200 that the information is not applicable. To do.

  Alternatively, in the server 100, flag information indicating whether or not each user may be a search target shown in the above embodiment is registered in advance, and the flag may be a search target. The server 100 may transmit user information to the user terminal 200 when indicating good.

  (2) In the above-described embodiment, the estimation unit 131 specifies a user who has information that matches all transmitted appearance information. However, this is not the case.

For example, when there are a plurality of transmitted appearance information, the estimation unit 131 may search whether there is a user who matches a certain amount or more of the appearance information. For example, when there are five pieces of appearance information as the appearance information, the estimation unit 131 may search for a user that matches at least four of them.
This makes it easy to search for a user desired by the user terminal that has transmitted the user information request.

  (3) Although not specifically described in the above embodiment, a data format for transmitting appearance information may be determined in advance, and the user may input appearance information according to the format and transmit it to the server. Alternatively, the server 100 may provide a GUI (Graphical User Interface) for the input to the user terminal, and a plurality of pieces of information about the appearance are prepared at the user terminal, and the selection may be input from among them. . Alternatively, when the appearance information is transmitted as text from the user terminal to the server 100, when the server 100 has a so-called morphological analysis capability, the text is analyzed and information corresponding to the appearance information is extracted.
