The registration permission/inhibition determination unit 26 is realized by, for example, the CPU 201 and the like, and based on the social graph created by the graph creation unit 25, selects users among the user IDs included in the received friend relationship registration request who update the friendship relationship as friends. Determine ID. That is, if the user ID of the user name "suzuki" is included in the social graph with the user name "satoh" at the distance N or less, the registration possibility determination unit 26 determines that the user name "satoh" and " suzuki" as a friend and update the friendship relationship. On the other hand, if the user ID of the user name "suzuki" is not included in the social graph, the registration availability determination unit 26 determines that the user names "satoh" and "suzuki" are not friends. For example, if the distance N is 2 or 3, this means making friends with users who have "friends in common" or making users with "friends of friends in common" friends.

The friend relationship database 27 is realized by, for example, the storage device 204, and stores a friend relationship table in which users registered as friends of the user are managed for each user ID. Here, the friend relationship database 27 will be described with reference to FIG. FIG. 10 is a diagram showing an example of a friend relation database.

As shown in FIG. 10, the friend relationship database 27 has data items such as user IDs and user names of users who are friends (have a friend relationship) with the user of this user ID for each user ID. In the example of FIG. 10, the user with the user ID "uid001" (user name "satoh") is the user with the user ID "uid005" (user name "sasaki") or the user with the user ID "uid007" (user ID "nakamura"). ) and others are shown to be friends. In this way, the friend relationship database 27 stores a friend relationship table in which users registered as friends (that is, users who have a friend relationship) are managed for each user.

<Details of processing>
Next, the details of the processing of the service providing system 1 according to this embodiment will be described.

≪Search processing≫
As in the first embodiment, the user of the mobile terminal 10A (user ID "uid001", user name "satoh") searches for other mobile terminals 10 within a predetermined range around the own mobile terminal 10A. The processing to be performed will be described with reference to FIG. 11 . FIG. 11 is a flowchart of an example of search processing according to the second embodiment.

In step S1101, the user of the mobile terminal 10A performs an operation to search for other mobile terminals 10 within a predetermined range (for example, several centimeters to several tens of meters) around the mobile terminal 10A. Then, the input unit 12 of the mobile terminal 10</b>A accepts the operation and requests the search processing unit 13 to search for another mobile terminal 10 . Then, the search processing unit 13 of the mobile terminal 10A transmits the response request information within a predetermined range around the mobile terminal 10A for a predetermined time (for example, one second to several seconds).

On the other hand, the search processing unit 13 of another mobile terminal 10 that has received the response request information from the mobile terminal 10A transmits response information to the received response request information to the mobile terminal 10A or the server device 20 . Here, the transmitted response information includes the user ID, user name, etc. of the user of the mobile terminal 10 that transmitted the response information. When receiving the response information from the mobile terminal 10, the server device 20 transmits a list of user IDs, user names, and the like included in the received response information to the mobile terminal 10A, which is the source of the response request information. Also, when the server device 20 receives the response information, the response information may not include the user name. At this time, the server device 20 may acquire the user name corresponding to the user ID included in the received response information from a predetermined storage area.

Here, hereinafter, as in the first embodiment, it is assumed that the mobile terminal 10A receives the user IDs and user names of the mobile terminals 10B, 10C, 10D, and the like.

In step S1102, the search processing unit 13 of the mobile terminal 10A determines whether or not there is another mobile terminal 10 within a predetermined surrounding range. That is, the search processing unit 13 of the mobile terminal 10A determines whether or not the user ID, user name, etc. of the other mobile terminal 10 have been received. If the search processing unit 13 of the mobile terminal 10A does not receive the user ID, user name, etc. of the other mobile terminal 10, the process proceeds to step S1103.

In step S1103, the display unit 14 of the mobile terminal 10A causes the display device 106 or the like to display a message or the like indicating that there is no other mobile terminal 10 within a predetermined range around the mobile terminal 10A. This allows the user of the mobile terminal 10A to know that there are no other users around him.

As described above, the mobile terminal 10 according to the present embodiment uses short-range wireless communication such as BLE to search for other mobile terminals 10 in the vicinity. That is, unlike the first embodiment, the list of search results is not displayed. This is because, as will be described later in detail, by appropriately setting the distance N, a user who has a "common friend" or a user who has a "common friend's friend" is registered as a friend. . However, also in the present embodiment, a list of search results may be displayed in the same manner as in the first embodiment so that a user who wishes to register as a friend can be selected.

≪Friendship registration process≫
Next, processing performed after the search processing described above will be described with reference to FIG. FIG. 12 is a sequence diagram of an example of a friend relationship registration process according to the second embodiment.

In step S<b>1201 , the registration request unit 15</b>A of the mobile terminal 10</b>A transmits a friend relationship registration request to the server device 20 . Here, the friend relationship registration request includes the user ID and user name of the user of the mobile terminal 10A, the user ID and user name of the other mobile terminal 10 received in step S1101 of FIG. 11, and the like. That is, in this embodiment, the user ID "uid001" and the user name "satoh", the user ID "uid002" and the user ID "suzuki", the user ID "uid003" and the user name "tanaka" are included in the friend relationship registration request. , and user ID “uid004” and user name “yamada”.

In step S1202, upon receiving the friend relationship registration request, the graph creating unit 25 of the server apparatus 20 creates a social graph with a preset distance N or less for each of the user IDs included in the friend relationship registration request. do.

Here, FIG. 13 shows a social graph centered on the user ID "uid001" and having a distance of N=3 or less from the center. FIG. 13 is a diagram illustrating an example of a social graph; The social graph shown in FIG. 13 is composed of nodes of user IDs with the number of links of 3 or less (that is, the distance of 3 or less) centering on the user ID “uid001”. The graph creating unit 25 creates such a social graph for each of the user IDs included in the friend relationship registration request based on the distance N set in advance. That is, in the present embodiment, the graph creating unit 25 creates a social graph based on the preset distance N for each of the user IDs "uid001", "uid002", "uid003", and "uid004". Note that the distance N may be set to the same value for all users, or may be set to a different value for each user. Also, the user of the mobile terminal 10 may be able to set the distance N to a desired value by himself/herself.

In step S1203, for each user ID included in the friend relationship registration request, the registration availability determination unit 26 of the server apparatus 20 determines whether or not to register the friend relationship with the other user IDs included in the friend relationship registration request. determine whether

Specifically, the social graph of the user ID "uid001" created in step S1202 includes the other user IDs "uid002", "uid003", and "uid004" included in the friend relationship registration request. determine whether or not Then, the registration permission/inhibition determination unit 26 determines to register a friend relationship with another user ID included in the social graph of the user ID “uid001”. For example, in the example shown in FIG. 13, the user IDs "uid002" and "uid004" are included in the social graph of the user ID "uid001". Therefore, in this case, the registration availability determination unit 26 determines to register the user IDs "uid001" and "uid002" and the user IDs "uid001" and "uid004" as friends. On the other hand, the registration availability determination unit 26 determines that the user IDs "uid001" and "uid003" are not to be registered as friends.

Similarly, the registration permission/inhibition determination unit 26 determines whether or not the user IDs "uid003" and "uid004" are included in the social graph of the user ID "uid002". Similarly, the registration propriety determination unit 26 determines whether or not the user ID "uid004" is included in the social graph of the user ID "uid003".

In this way, the registration permission/inhibition determination unit 26 determines whether or not the social graph of one user included in the friend relationship registration request includes another user included in the registration request. In other words, the registration permission/inhibition determination unit 26 determines whether or not the distance between the one user included in the friend relationship registration request and the other user included in the registration request is equal to or less than the preset value N. do. Then, it is determined that users whose distance is N or less are registered as friends.

In step S1204, the registration processing unit 22A of the server device 20 updates the friend relation table of the user ID determined to be registered as a friend relation in the above step S1203 of the friend relation database 27. FIG.

For example, if it is determined in step S1203 that the user IDs "uid001" and "uid002" are to be registered as friendships, the registration processing unit 22A adds Add a record with user ID "uid002". Similarly, the registration processing unit 22 adds a record of the user ID “uid001” to the table of the user ID “uid002” of the friend relation database 27 . As a result, the user with the user ID "uid001" and the user with the user ID "uid002" become friends and can exchange messages with each other.

In step S1204, if the user IDs determined to be registered as friends in step S1203 are already friends (if friendships are registered), nothing should be done.

In step S1205-1, the registration processing unit 22A of the server device 20 transmits the results of the friendship registration in step S1204 to the mobile terminals 10B to 10D. Similarly, in step S1205-2, the registration processing unit 22A of the server device 20 transmits the result of the friendship registration in step S1204 to the mobile terminal 10A. In this way, the registration processing unit 22A transmits the result of the friendship registration to the mobile terminal 10 of each user ID included in the friendship registration request. Here, for example, the user ID of the user who became friends with the user of the mobile terminal 10 of the transmission destination (that is, the user whose friendship was registered) is included in the friend relationship registration result transmitted by the registration processing unit 22A. and user name. Thereby, the user of the portable terminal 10 can know other users who have become friends with him/herself.

As described above, when the server device 20 according to the present embodiment receives a friend relationship registration request including a plurality of user IDs from the mobile terminal 10, the social graph of each user ID is calculated based on the distance N set in advance. to create Then, the server device 20 according to the present embodiment mutually registers a plurality of users as friends based on the created social graph. As a result, in the service providing system 1 according to the present embodiment, it is possible to register friendship relationships with each of a plurality of users at once.

In this embodiment, it is determined whether or not to mutually register the user IDs included in the friend relationship registration request as a friend relationship, but the present invention is not limited to this. For example, it may be determined whether to register the user of the mobile terminal 10A and the users of the mobile terminals 10B to 10D as friends (in this case, for example, the user of the mobile terminal 10B and the mobile terminals 10B and 10D may be registered as friends). Do not be friends with 10C users).

Also, in the present embodiment, a case has been described in which multiple users are mutually registered as friends, but the present invention is not limited to this, and a group relationship including multiple users may be registered based on a social graph. That is, in step S1201 of FIG. 12, the mobile terminal 10 may transmit a group-related registration request including user IDs and user names of a plurality of users forming a group to the server device 20 . In this case, the server device 20 creates a group including the user of the mobile terminal 10 that transmitted the registration request and the users included in the social graph within the distance N of this user, among the plurality of users included in the registration request. Register the relationship.

It should be noted that the present invention is not limited to the specifically disclosed embodiments above, but is capable of various modifications and alterations without departing from the scope of the claims.
