That is, each of the mobile terminals 1A, 1B, and 1C may be called a communication state determination device. The mobile transmitting devices 2A, 2B, and 2C are small devices that transmit beacon signals that can be carried by each user. User A, user B, and user C are employees in the same company, for example. It is assumed that the user A and the user B are away from each other and are close to each other. It is assumed that the user C is working at his seat. The seat transmission device 3C is set in the seat of the user C. The mobile terminals 1A, 1B, and 1C are collectively referred to as the mobile terminal 1. The mobile transmitting devices 2A, 2B, and 2C are collectively referred to as the mobile transmitting device 2. The mobile terminal 1 has a function of receiving a beacon signal transmitted from the mobile transmission device 2.

In the example shown in FIG. 1, since the user A and the user B are close to each other, the mobile terminal 1A can receive the beacon signal transmitted from the mobile transmission device 2B (the beacon signal transmitted by the mobile transmission device 2B).

The reception state is a reception continuation period or reception intensity. Significant communication is, for example, a state where users are close to each other and have a conversation. By determining that the users have performed significant communication, the mobile terminal 1 can detect that the relationship between the users is strong or that the relationship between the users is strengthened. Note that each of the mobile terminals 1A, 1B, and 1C is basically in a position where the user holding the mobile terminal can receive the beacon signal from the mobile transmitting device 2 held with the mobile terminal.

FIG. 2 is a second diagram showing an outline of a communication state determination system including the communication state determination device according to the same embodiment.
The example shown in FIG. 2 is different from the example shown in FIG. 1 in that the position of the user C is close to the positions of the user A and the user B who are in close proximity and in significant communication with each other. ing.

In the example shown in FIG. 2, as in the example shown in FIG. 1, since the user A and the user B are close to each other, the mobile terminal 1A can receive the beacon signal transmitted from the mobile transmission device 2B (mobile). It exists within the radio wave range 2B-R of the beacon signal transmitted by the transmitter 2B. Further, in the example shown in FIG. 2, since the user C is seated at a position close to the user A and the user B, the mobile terminal 1A can receive the beacon signal transmitted from the mobile transmission device 2C (mobile transmission).

Further, the mobile terminal 1A is present at a position where the beacon signal transmitted from the seat transmission device 3C can be received (within the radio wave range 3C-R of the beacon signal transmitted by the seat transmission device 3C). The mobile terminal 1A also receives a beacon signal transmitted by the mobile transmission device 2A.

Further, since the user A and the user B are close to each other, the mobile terminal 1B is at a position where the beacon signal transmitted from the mobile transmitting device 2A can be received (transmitted by the mobile transmitting device 2A) as in the example shown in FIG. It exists within the radio wave range 2A-R of the beacon signal. Further, in the example shown in FIG. 2, since the user C is seated at a position close to the user A and the user B, the mobile terminal 1B can receive the beacon signal transmitted from the mobile transmission device 2C (mobile transmission). It exists within the radio wave range 2C-R of the beacon signal transmitted from the device 2C. Furthermore, the mobile terminal 1B is present at a position where the beacon signal transmitted from the seat transmission device 3C can be received (within the radio wave range 3C-R of the beacon signal transmitted by the seat transmission device 3C). The mobile terminal 1B also receives a beacon signal transmitted by the mobile transmission device 2B.

User C is working at his/her own seat near the positions of user A and user B. Therefore, the mobile terminal 1C exists in a position where the beacon signal transmitted from the mobile transmission device 2A can be received (within the radio wave range 2A-R of the beacon signal transmitted by the mobile transmission device 2A). Further, the mobile terminal 1C is present at a position where the beacon signal transmitted from the mobile transmission device 2B can be received (in the radio wave range 2B-R of the beacon signal transmitted by the mobile transmission device 2B). The mobile terminal 1C also receives a beacon signal transmitted from the mobile transmission device 2C or the seat transmission device 3C.

On the other hand, when each of the mobile terminals 1A, 1B, and 1C receives a beacon signal indicating that it is not a place for communication, the user corresponding to the transmitting device of the beacon signal is not in a significant communication state. judge. That is, when each of the mobile terminals 1A, 1B, and 1C receives a beacon signal indicating that it is not a place for communication, the user corresponding to the transmitting device of the beacon signal is significantly different from the user holding the own terminal. It is determined that the user is not the user who has communicated, and is excluded from the communication target.

In the example shown in FIG. 2, the users A, B, and C are close to each other, but the user C may be seated in the seat and may not participate in the conversation. Therefore, it is preferable to exclude the user C among the users A, B, and C from the communication targets. The mobile terminals 1A and 1B detect the identification information of the device that has transmitted the beacon signal based on the beacon signal transmitted from the seat transmission device 3C. When the mobile terminals 1A and 1B determine that the identification information of the detected beacon signal is the identification information indicating that it is not a place to communicate, the portable terminals 1A and 1B correspond to the seat transmission device 3C that is the transmission source of the beacon signal that specifies the identification information. The user C who does is excluded from the communication target. The mobile terminals 1A and 1B determine that the user A and the user B other than the excluded user C are significant communication targets.

It is a computer having a configuration such as (Hard Disk Drive) 56.

FIG. 6 is a first diagram showing a processing flow of the communication state determination system.
Next, the processing flow of the communication state determination system 100 will be described.
The user operates the mobile terminal 1 to perform an application start operation. Then, the CPU of the mobile terminal 1 executes the communication state determination program. As a result, the functions of the communication unit 11, the communication target candidate specifying unit 12, and the communication target information generating unit 13 are configured inside the mobile terminal 1.

The communication target information generation unit 13 waits for reception of a beacon signal (step S101). The beacon signal transmitted from the mobile transmission device 2 or the seat transmission device 3 is a signal transmitted using, for example, the Bluetooth (registered trademark) technology. When the Bluetooth (registered trademark) receiver included in the mobile terminal 1 receives the beacon signal, the communication target information generation unit 13 acquires the information of the signal. The communication target information generation unit 13 acquires the identification information and the type information of the transmission device included in the information of the beacon signal (step S102). Further, the communication target information generation unit 13 acquires the reception strength of the beacon signal from the Bluetooth (registered trademark) receiver of the mobile terminal 1 (step S103). The communication target information generation unit 13 generates a beacon signal reception table in which at least the identification information of the transmission device, the type information, the reception intensity, and the reception time are associated and registered in the storage unit 14 (step S104).

The beacon signal reception table shown in FIG. 7 is an example of a table created by the mobile terminal 1A held by the user A in the example of FIG. 1 in which the user A and the user B are close to each other. 1 A of portable terminals exist in the position which can receive the beacon signal which the portable transmission apparatus 2B (2nd transmission apparatus) which the user B hold|transmits transmits. Therefore, the mobile terminal 1A receives the beacon signal transmitted by the mobile transmitter 2B, generates the beacon signal reception table shown in FIG. 7 based on the beacon signal, and registers the beacon signal reception table in the storage unit 14. Since the mobile terminal 1A also receives the beacon signal transmitted by the mobile transmission device 2A (first transmission device) held by the user A, the transmission device is transmitted based on the reception of the beacon signal transmitted by the mobile transmission device 2A. A beacon signal reception table holding 2A as the identification information of may be generated. Note that a beacon signal reception table corresponding to each transmitting device may be created based on reception of a beacon signal from each of the mobile transmitting device 2 and the seat transmitting device 3 (second transmitting device). The information based on the beacon signals may be collected in one beacon signal table to generate the table. The mobile terminal 1A may stop the process shown in FIG. 6 when the beacon signal transmitted by the mobile transmission device 2A (first transmission device) held by the user A cannot be received.

After executing the communication state determination program, the communication target candidate identification unit 12 starts a process of identifying a communication target candidate (step S105). Specifically, the communication target candidate specifying unit 12 determines whether or not the beacon signal reception table includes the identification information indicating the seat transmitting device 3. When determining that the beacon signal reception table includes the identification information indicating the seat transmitting device 3, the communication target candidate specifying unit 12 specifies the mobile transmitting device 2 corresponding to the seat transmitting device 3. To identify the mobile transmitting device 2 corresponding to the seat transmitting device 3, the mobile terminal 1 stores in advance a correspondence table of the identification information of the mobile transmitting device 2 corresponding to the identification information of the seat transmitting device 3 in the storage unit 14. The mobile transmission device 2 corresponding to the seat transmission device 3 may be specified based on the correspondence relationship. Alternatively, the mobile terminal 1 may transmit the identification information of the seat transmission device 3 to the server device 10 and receive the identification information of the mobile transmission device 2 corresponding to the seat transmission device 3 from the server device 10. The relationship between the mobile transmission device 2 corresponding to the seat transmission device 3 means that the seat transmission device 3 installed or placed in the user's seat shown in FIGS. Means the relationship of the mobile transmitter 2. The communication target candidate identification unit 12 is a list of the IDs of the mobile transmission devices 2 indicated by the received beacon signals, and excludes the IDs of the mobile transmission devices 2 corresponding to the seat transmission devices 3 from the mobile transmission devices 2. Then, the communication target candidate information is generated (step S106). The communication target candidate specifying unit 12 outputs the communication target candidate information to the communication target information generating unit 13.

The communication target information generation unit 13 acquires the beacon signal reception table from the storage unit 14. The beacon signal reception table is information registered in the storage unit 14 generated after the communication state determination program is executed. The communication target information generation unit 13 identifies the mobile transmitter device 2 included in the communication target candidate information, which is repeatedly receiving the beacon signal for a certain reception duration from the beacon signal reception table. In addition, the communication target information generation unit 13 determines the reception intensity of the mobile transmission device 2 that repeatedly receives the beacon signal for a certain reception duration period among the mobile transmission devices 2 included in the communication target candidate information based on the beacon signal reception table. However, it is determined whether the intensity is equal to or higher than a predetermined intensity during that period. The communication target information generation unit 13 keeps receiving the beacon signal for a certain reception continuation period among the mobile transmission devices 2 included in the communication target candidate information, and the mobile transmission having the reception intensity equal to or higher than a predetermined intensity during the period. The device 2 is specified. Then, the communication target information generation unit 13 generates communication target information including the identified ID of the mobile transmission device 2 and the like (step S107).

The generated communication target information has a correspondence relationship between the ID of the mobile terminal 1A and the ID of another mobile transmission device 2 that is the source of the beacon signal repeatedly received by the mobile terminal 1A for a certain reception duration and at a predetermined intensity or more. And the predetermined strength, and a reception duration period in which a beacon signal having the predetermined strength or higher is received may be included. When the mobile terminal 1A receives a beacon signal transmitted from a plurality of other mobile transmitting devices 2 with a predetermined reception duration or more for a predetermined intensity or more, the communication target information includes other mobile transmitting devices 2 A plurality of combinations of the ID, the reception period, and the reception intensity in each reception. The communication target information generation unit 13 calculates the average distance to the other mobile transmission device 2 based on the average value of the reception intensity of the other mobile transmission device 2, and the information of the average distance is used as the information of the other mobile transmission device. It may be included in the communication target information in association with the second identification information. Note that the communication target information generation unit 13 stores in advance the information of the mobile transmission device 2A held by the user A in pair with the mobile terminal 1A which is the own device, and the identification information of the mobile transmission device 2A is the communication target. May be deleted.

The communication target information generation unit 13 instructs the communication unit 11 to transmit the generated communication target information to the server device 10. The communication unit 11 transmits the communication target information to the server device 10 (step S108). The server device 10 receives the communication target information. The server device 10 registers the communication target information in the database provided in the device itself in association with the identification information of the mobile terminal 1A (step S109).

The server device 10 provides a service using the communication target information. At this time, the server device 10 generates image information using the communication target information (step S110). The server device 10 identifies the mobile terminal 1 that is the transmission source of the communication target information used to generate the image information. The server device 10 transmits the generated image information to the specified mobile terminal 1 (step S111). The mobile terminal 1 receives the image information and outputs it on the screen of its own terminal (step S112). The image information may be, for example, a list of users holding other mobile transmitting devices 2 included in the communication target information generated by the mobile terminal 1.
The server device 10 receives the communication target information from the mobile terminal 1 included in the communication state determination system 100, and repeats the same processing. Further, the server device 10 periodically and repeatedly receives communication target information from each mobile terminal 1, and repeats the same processing.

FIG. 8 is a second diagram showing the processing flow of the communication state determination system 100.
In the process flow described with reference to FIG. 6, a part of the process performed by the mobile terminal 1 may be performed by the server.
For example, the mobile terminal 1 generates communication target information. The communication target information may include the identification information of the mobile transmitting device 2 corresponding to the seat transmitting device 3. Then, the server device 10 performs a process of excluding the identification information of the mobile transmission device 2 corresponding to the seat transmission device 3 from the communication target information received from the mobile terminal 1, instead of the process of the mobile terminal 1 described above. You can

In this case, as shown in FIG. 8, the processing up to step S201 to step S204 is the same as the processing up to step S101 to step S104 shown in FIG. That is, the communication target information generation unit 13 waits for reception of the beacon signal (step S201). When the Bluetooth (registered trademark) receiver included in the mobile terminal 1 receives the beacon signal, the communication target information generation unit 13 acquires the information of the signal. The communication target information generation unit 13 acquires the ID of the transmitting device and the type information included in the information of the beacon signal (step S202). Further, the communication target information generation unit 13 acquires the reception intensity of the beacon signal from the Bluetooth (registered trademark) receiver of the mobile terminal 1 (step S203).

Next, the communication target candidate specifying unit 12 generates communication target candidate information indicating a list of identification information of the mobile transmission device 2 and the seat transmission device 3 based on the beacon signal reception table (step S205). The communication target candidate specifying unit 12 outputs the communication target candidate information to the communication target information generating unit 13.

The communication target information generation unit 13 acquires the beacon signal reception table from the storage unit 14. The beacon signal reception table is information registered in the storage unit 14 generated after the communication state determination program is executed. The communication target information generation unit 13 can determine that the mobile communication device 2 or the seat transmission device 3 included in the communication target candidate information is still receiving the beacon signal from the beacon signal reception table for a certain reception duration. The transmitter 2 and the seat transmitter 3 are specified. In addition, the communication target information generation unit 13 continues to repeatedly receive the beacon signal for a certain reception continuation period among the mobile transmission device 2 and the seat transmission device 3 included in the communication target candidate information based on the beacon signal reception table. It is determined whether or not the reception intensity of the mobile transmission device 2 or the seat transmission device 3 that is present is equal to or higher than a predetermined intensity during that period.

The communication target information generation unit 13 calculates each average distance to the other mobile transmission device 2 or the seat transmission device 3 based on the average value of the reception intensity of the other mobile transmission device 2, and the information of each average distance. May be included in the communication target information in association with the IDs of the other mobile transmission device 2 and the seat transmission device 3. In addition, the communication target information generation unit 13 stores in advance the information of the mobile transmission device 2A held by the user A paired with the mobile terminal 1A, which is the own device, and based on the information, obtains the ID of the mobile transmission device 2A. A process of deleting from the communication target may be performed.

The communication target information generation unit 13 instructs the communication unit 11 to transmit the generated communication target information to the server device 10. The communication unit 11 transmits the communication target information to the server device 10 (step S207). The server device 10 receives the communication target information. The server device 10 registers the communication target information in the database provided in its own device in association with the identification information of the mobile terminal 1A (step S208).

Here, the server device 10 performs the same process as the communication target candidate specifying unit 12 included in the mobile terminal 1. The server device 10 provides a service using the communication target information. At this time, the server device 10 performs a process of deleting the ID of the mobile transmitting device 2 corresponding to the seat transmitting device 3 from the received communication target information. Specifically, the server device 10 determines whether the received communication target information includes the ID of the seat transmitting device 3. When the server device 10 determines that the communication target information includes the ID of the seat transmitting device 3, the server device 10 specifies the mobile transmitting device 2 corresponding to the seat transmitting device 3. To specify the mobile transmitting device 2 corresponding to the seat transmitting device 3, the server device 10 stores in advance a correspondence table of the IDs of the mobile transmitting devices 2 corresponding to the IDs of the seat transmitting devices 3 in the storage unit. The mobile transmitting device 2 corresponding to the seat transmitting device 3 may be specified based on the correspondence. In the received communication target information, the server device 10 performs a process of deleting the ID of the mobile transmission device 2 corresponding to the seat transmission device 3 from the list of the IDs of the mobile transmission device 2 indicated by the information (step S209). ).

The server device 10 generates image information using the communication target information in which the identification information of the mobile transmitting device 2 corresponding to the seat transmitting device 3 has been deleted by the process of step S209 (step S210). The server device 10 identifies the mobile terminal 1 that is the transmission source of the communication target information used to generate the image information. The server device 10 transmits the generated image information to the specified mobile terminal 1 (step S211). The mobile terminal 1 receives the image information and outputs it on the screen of its own terminal (step S212). The image information may be, for example, a list of users holding other mobile transmitting devices 2 included in the communication target information generated by the mobile terminal 1.
The server device 10 receives the communication target information from the mobile terminal 1 included in the communication state determination system 100 and repeats the same processing. Further, the server device 10 periodically and repeatedly receives communication target information from each mobile terminal 1, and repeats the same processing.

In the processes of steps S201 to S212 described above, the server device 10 performs a process of excluding the identification information of the mobile transmission device 2 corresponding to the seat transmission device 3 from the communication target information received from the mobile terminal 1. Instead of the processing of the terminal 1. The server device 10 may further perform the process performed by the mobile terminal 1 instead. For example, the beacon signal reception table in step S204 described above may be registered in the database 24 of the server device 10, and the server device 10 may generate communication target candidate information.

According to the above-described process, the mobile terminal 1 holds the beacon signal from the mobile transmitting device 2 held by the user holding the own terminal (first target) together with the own terminal and the other user (other target) holding the beacon signal. The information on the reception state of the beacon signal transmitted from the portable transmission device 2 or the seat transmission device 3 is acquired. Then, the mobile terminal 1 determines, based on the acquired information on the reception state of each beacon signal, the other user who holds the other terminal in a significant communication state with the own user who holds the own terminal. When the mobile terminal 1 receives the beacon signal transmitted from the mobile transmission device 2 held by another user for a predetermined time or longer, the other user is brought into a significant communication state with the own user holding the own terminal. It is determined that the user is another user. Alternatively, when the mobile terminal 1 continuously receives a beacon signal transmitted from the mobile transmission device 2 held by another user with a predetermined strength or more for a predetermined time or more, the mobile terminal 1 refers to another user as the own user holding the own terminal. And a significant communication state is established, and it is determined to be another user. The significant communication state is, for example, a state in which users are close to each other and have a conversation. The mobile terminal 1 can detect that the relationship between the users is strong or strong by determining that the users are in the communication state. Further, according to the processing of the communication state determination system 100 described above, when the mobile terminal 1 receives a beacon signal indicating that it is not a place for communication, the mobile terminal 1 significantly identifies the user corresponding to the transmitting device of the beacon signal. Since it is excluded from the communication targets, it is possible to more accurately specify the relationship between the user who holds the mobile terminal 1 and another user who is in a significant communication state.
