  By the way, as described below, the above-described conventional technology has problems in terms of cost, establishment of communication, and the like.

  That is, in the case of performing communication via a network, there is a problem that communication cannot be established when a delay or failure occurs in the network, in addition to a problem that a communication fee is charged.

  On the other hand, when communicating directly between mobile communication devices without going through a network, since the mobile communication device is assumed to move, the communicable range cannot catch up with the moving distance, and communication cannot be established. There was a problem. In particular, when communication is performed between vehicles equipped with mobile communication devices, the range of movement of the vehicle is wide, so that the communicable range cannot catch up with the movement distance and communication cannot be established. This is a big problem, and more prominent when performing group communication between a plurality of mobile communication devices.

On the other hand, in the incoming call information added to the data, the mobile communication device of each group member who is the destination of the data Information constant is if it contains all is characterized by comprising a data relay means for stopping the relay of the predetermined data.

According to a second aspect of the present invention, the data relay means receives data received from the mobile communication device related to the other group member, and specifies its own mobile communication device from the destination of the data. It is characterized by deleting information and relaying.

In the invention according to claim 3, the data relay means stops relaying the data when the data received from the mobile communication device related to the other group member is the same as the data already received. It is characterized by doing.

Further, in the invention according to claim 4, the data relay means, when the number of relays of data received from the mobile communication device related to the other group member has reached a predetermined number of relays, The relay is stopped.

According to the present invention, a group list in which each group member is enumerated for a predetermined group is stored, and predetermined data (for example, image data or audio data to be disclosed to each group member) is stored based on this group list. Etc.) without relaying the network to each group member, and when the destination of the predetermined data designates another mobile communication device, the predetermined data is relayed without passing through the network. Therefore, even if the distance between the mobile communication devices is long, data can be relayed to other mobile communication devices, and communication between the mobile communication devices of the group can be reliably established at low cost.

In addition, according to the present invention, since a plurality of data destined for each group member is transmitted, compared to a case where one data addressed to all of the group members is transmitted, an incoming data or Relaying can be performed easily.

In addition, according to the present invention, when transmitting one data addressed to all the members of the group and receiving and relaying the received predetermined data, the incoming information for identifying the mobile communication device of itself is specified. When the destination of the predetermined data is all included in the incoming information added to the data, the transmission of the data is stopped, so that each group member The amount of data relay can be reduced compared to sending a plurality of data destined for a destination, and it is possible to prevent sending unnecessary data (that is, data that has already arrived at all destinations). . In addition, it is possible to reduce the adverse effect on communication traffic caused by unnecessary transmission of data.

Further , according to the present invention, when one piece of data destined for all the members of the group is transmitted and the destination of the received predetermined data is self, the predetermined data is received and the self is sent from the destination. Since it is deleted and sent, the amount of data relay can be reduced compared to sending multiple data addressed to each group member, and when all destinations arrive, the destination disappears and relaying stops. It becomes possible to prevent transmission of unnecessary data. In addition, it is possible to reduce the adverse effect on communication traffic caused by unnecessary transmission of data.

Further , according to the present invention, when the same data as the already relayed data is received, the relay of the data is stopped, so that unnecessary data transmission can be prevented. In addition, it is possible to reduce the adverse effect on communication traffic caused by unnecessary transmission of data.

Further , according to the present invention, when the number of relays of the received data has reached a predetermined number, the transmission of the data is stopped, so that the situation where the relay of data is performed infinitely is a simple processing procedure. Can be prevented. In addition, it is possible to reduce the adverse effect on communication traffic caused by unnecessary transmission of data.

In addition, according to the present invention, a data list enumerating data that can be shared by other group members is stored, and the data list is transmitted to other group members. It is possible to reliably grasp data at low cost.

Further , according to the present invention, another communication device that can communicate with the mobile communication device accepts a member who desires to join a predetermined group, and creates a group list that enumerates the accepted group members. Since the mobile communication device generates and stores the generated group list, other communication devices (for example, a server device installed in a center or the like) without the burden of accepting membership in the group at the mobile communication device. Thus, it becomes possible to form group members.

Further , according to the present invention, a member who desires to join a predetermined group is accepted, a group list that enumerates the accepted group members is generated, and the generated group list is transmitted to the mobile communication device.

[Data Transmission Processing by Mobile Communication Device (Example 1)]
Next, the flow of data transmission processing by the mobile communication device according to the first embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating the flow of data transmission processing by the mobile communication device according to the first embodiment. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when there is an instruction to transmit data (image data or the like) from the user (Yes at Step S401), the transmission processing unit 22a reads the group list from the group list storage unit 21a (Step S402).

  Subsequently, the transmission processing unit 22a reads data for which a transmission instruction has been issued from the data storage unit 21b (step S403). Then, the transmission processing unit 22a generates transmission data for each destination for which a transmission instruction has been received from the user, from the read group list and data (step S404). For example, the transmission processing unit 22a generates transmission data addressed to the group members B and C for each destination.

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Effect of Example 1]
As described above, according to the first embodiment, the mobile communication device stores a group list in which each group member is listed for a predetermined group. Based on the group list, predetermined data (for example, When image data or audio data to be disclosed to each group member is transmitted to each group member via the network, and the destination of the predetermined data designates another mobile communication device Relays the specified data as it is without going through the network, so even if the distance between the mobile communication devices is long, the data is relayed to other mobile communication devices, and communication between the mobile communication devices of the group is performed. It becomes possible to establish reliably at low cost.

  Further, according to the first embodiment, since this mobile communication device transmits a plurality of data addressed to each group member, when transmitting one data addressed to all the group members, In comparison, it is possible to easily receive and relay data.

  The mobile communication device according to the first embodiment has been described so far, but the present invention may be implemented in various different forms other than the above-described embodiments. Therefore, another embodiment included in the present invention will be described below as a second embodiment.

(1) Sending data by adding a group list In the above embodiment, each group member including a transmission source ID (for example, A), a transmission destination ID (for example, B and C), and predetermined data. However, the present invention is not limited to this, and further generates outgoing data to which a group list is added as information for specifying a group. You may make it transmit. Therefore, an outline of the mobile communication device in this case will be described below with reference to FIG. FIG. 6 is a diagram for explaining the outline of the mobile communication device according to the second embodiment.

  When the mobile communication device A transmits predetermined data (for example, image data or audio data) to the other mobile communication devices B and C in the group without going through the network, the transmission source ID (For example, A), transmission destination ID (for example, B or C), and predetermined data, as well as data for outgoing destinations each of the group members B and C to which a group list is added as information for specifying a group Is generated and transmitted for each destination (transmission destination ID) (see (1) and (2) in FIG. 1).

  In this way, since this mobile communication device adds a group list to predetermined data as information for specifying a predetermined group and transmits the information, the mobile communication device that has received such data receives this group when returning data. It is possible to use the list (for example, grasping that the incoming data is sent to the group and replying to each group member).

(2) Information for specifying a group In the above-described embodiment, a case has been described in which data for transmission including a group list is generated and transmitted as information for specifying a group. However, the present invention is not limited to this. Alternatively, transmission data including a group ID as information for specifying a group may be generated and transmitted. Therefore, hereinafter, the mobile communication apparatus in this case will be described with reference to FIG. FIG. 7 is a diagram illustrating a configuration example of a group list according to the second embodiment.

  Specifically, the group list storage unit 21a of the mobile communication device in this case, for example, as shown in FIG. 7, the device ID uniquely assigned to the mobile communication device of each group member. Not only a group list but also a group ID unique to the group is stored together. Then, the transmission processing unit 22a generates transmission data for printing each of the group members including the transmission source ID, the transmission destination ID, predetermined data, and the group ID as information for specifying the group as the destination. To send.

  In this way, since this mobile communication device adds a group ID to predetermined data as information for specifying a predetermined group and transmits the information, the mobile communication device that has received such data receives this group at the time of data return. It is possible to use the ID (for example, grasping that the incoming data is transmitted to the group and returning it to each group member).

(3) Storage of a plurality of group lists In the above embodiment, the case where one group list is stored in the group list storage unit 21a has been described. However, the present invention is not limited to this, and a plurality of group lists are stored. A group list may be stored. Therefore, hereinafter, the mobile communication apparatus in this case will be described with reference to FIG. FIG. 8 is a diagram illustrating information stored in the group list storage unit 21a according to the second embodiment.

  Specifically, the group list storage unit 21a of the mobile communication device in this case uniquely assigns each group member (for example, a device of each group member, for example) as illustrated in FIG. Device IDs) are listed and stored, and a group ID unique to the group is stored. Then, for example, the transmission processing unit 22a accepts a user's transmission instruction and transmits each group member to which a group list selected from a plurality of groups stored in the group list storage unit 21a is added as a destination. Data is generated and sent to each destination. It is also possible to select a group ID instead of a group list from the group list storage unit 21a, and generate and send outgoing data for each group member to which the group ID is added.

  Thus, the mobile communication device stores a group list for each of a plurality of groups, and transmits predetermined data based on a group list selected from the plurality of stored groups. Communication between mobile communication devices in each group can be reliably established at low cost.

(4) Data List Sharing In the above embodiment, a data list that lists data that can be shared by other group members may be stored, and the data list may be transmitted to each group member. Therefore, hereinafter, the mobile communication apparatus in this case will be described with reference to FIG. FIG. 9 is a diagram illustrating data list sharing according to the second embodiment. For example, as illustrated in FIG. 9, the mobile communication devices A, B, and C store data lists (for example, aaa, bbb, ccc) that can be shared by other group members. Then, the mobile communication devices A, B, and C respectively transmit the data list to other mobile communication devices.

  In this way, this mobile communication device stores a data list that lists data that can be shared by other group members, and transmits the data list to other group members. It is possible to reliably grasp data that can be shared at low cost.

  By the way, in the above-described embodiment, the case where the mobile communication apparatus that has received the data always relays the data has been described. However, the present invention is not limited to this, and the received data is in a predetermined case. May be stopped. Therefore, in a third embodiment below, a case where data relay is stopped in a mobile communication device mounted on a vehicle will be described.

If the data ID is not the same as the ID of the data already relayed, the received data is not sent through the network. (See (5) in FIG. 10).

  And the mobile communication apparatus C located in the range which can communicate with the mobile communication apparatus D without via a network receives this data relayed from the mobile communication apparatus B without via a network. Here, the mobile communication device C confirms the transmission destination ID (destination) of the received data, and as a result, if the transmission destination ID does not designate another mobile communication device, the mobile communication device C has received it. The data is received as it is (see (6) in FIG. 10).

[Configuration of Mobile Communication Device (1) (Example 3)]
Next, the configuration (1) of the mobile communication device according to the third embodiment will be described. Note that the mobile communication device according to the third embodiment has basically the same configuration as the mobile communication device shown in FIG. 2, but differs in the points described below.

  That is, the transmission processing unit 22a of the communication control unit 22 receives predetermined data (for example, image data and audio data) from the user via the display 11 and a destination (for example, the mobile communication device B or C) of the predetermined data. ) Is received, based on the group list stored in the group list storage unit 21a and the predetermined data stored in the data storage unit 21b, the transmission source ID (for example, A) and the transmission destination ID (for example, , B or C) and the predetermined data, the data for transmission is generated for each group member to which the data ID for specifying the data for transmission is added.

  Further, the data receiving unit 22c of the communication control unit 22 confirms the transmission destination ID (destination) of the data received from the other mobile communication device, and as a result, the data transmission destination ID is the other mobile communication. If the device is to be designated, a relay command is sent to the data relay unit 22e together with the data so as to relay it without going through the network. However, even if the transmission destination ID designates another mobile communication device, if the ID of the received data is the same as the ID of the already relayed data, the relay is performed to the data relay unit 22a. The relay of the received data is stopped without sending the command.

  Specifically, when the data receiving unit 22c receives data transmitted from another mobile communication device using a function such as Bluetooth or infrared communication, the data receiving unit 22c sets a destination ID (destination) of the data. If the transmission destination ID (destination) of the data designates another mobile communication device as a result of the confirmation, further confirmation of the data ID added to identify the data I do. As a result, when the data ID is the same as the ID of data that has already sent a relay command to the data relay unit 22e, the data reception unit 22c relays to the data relay unit 22e. The relay of the received data is stopped without sending the command.

[Processing of Mobile Communication Device (1) (Example 3)]
Next, the flow of the process (1) of the mobile communication device according to the third embodiment will be described with reference to FIG. FIG. 11 is a flowchart illustrating a flow of the process (1) of the mobile communication device according to the third embodiment. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when the data receiving unit 22c receives data from another mobile communication device without going through the network (Yes in step S1101), the data transmission destination ID (destination) is another mobile communication. It is confirmed whether or not the device is designated (step S1102). If the transmission destination ID of the data specifies another mobile communication device (Yes at step S1102), the data reception unit 22c determines that the data ID of the data has already been transmitted to the data relay unit 22e. It is confirmed whether or not it is the same as the ID of the data that has sent the relay command (step S1103).

  As a result, if the data IDs are the same (Yes at step S1103), the data receiving unit 22c stops relaying data without sending a command to the data relay unit 22e (step S1104). On the other hand, if the data IDs are not the same (No at step S1103), the data receiving unit 22c sends a relay command together with the data to the data relay unit 22e so as to relay the data without going through the network. The data relay unit 22e that received the relay command together with the data relays the data (step S1105).

  Here, returning to the description of step S1102, if the destination ID (destination) of the received data does not specify another mobile communication device (that is, the destination is self) (No in step S1102). The data receiving unit 22c sends an incoming call processing command together with the data to the incoming call processing unit 22d to receive the data as it is, and the incoming call processing unit 22d receiving the incoming call processing command together with the data receives the data as it is. An incoming call is received (step S1106). Further, when the received data ID is the same as the ID of the data that has already undergone the incoming call processing, the data receiving unit 22c does not receive an incoming call without sending an incoming call processing command to the incoming call processing unit 22d. It may be.

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Outline of Mobile Communication Device (2) (Example 3)]
By the way, in the above-described embodiment, the case where the relay of the received data is stopped by the data ID included in the data for transmission generated in the transmission processing unit 22a has been described, but the present invention is limited to this. Instead, data relay may be stopped based on the number of data relays. Therefore, hereinafter, a case will be described in which data relay is stopped depending on the number of data relays in the mobile communication device mounted on the vehicle.

  First, the outline (2) of the mobile communication device according to the third embodiment will be described with reference to FIG. FIG. 12 is a diagram for explaining the outline (2) of the mobile communication device according to the third embodiment. As shown in the figure, the owners of mobile communication devices A, B, and C belong to a predetermined group, and mobile communication devices A, B, and C are group members within the group to which each belongs. Is stored in a group list (for example, (A, B, C)). In addition, the mobile communication device A shown in the figure can communicate with other mobile communication devices B in the group via a network (for example, communication using a function such as Bluetooth or infrared communication). The mobile communication devices C are in a positional relationship that cannot communicate with other mobile communication devices C in the group via the network, and the mobile communication devices B and C and other mobile communication devices D outside the group. Are in a positional relationship in which communication is not possible via a network.

  Then, the mobile communication device A transmits predetermined data (for example, image data and audio data) to the other mobile communication devices B and C in the group without going through the network. Specifically, the mobile communication device A, based on the stored group list and predetermined data, the transmission source ID (for example, A), the transmission destination ID (for example, B and C), the predetermined data, Is generated and transmitted without going through the network (see (1) and (2) in FIG. 12).

  Next, the mobile communication device B located in a range where communication with the mobile communication device A can be performed without going through the network receives these data transmitted from the mobile communication device A without going through the network. Here, the mobile communication device B confirms the transmission destination ID (destination) of the received data, and as a result, when the transmission destination ID does not designate another mobile communication device (that is, the destination is In the case of self), the mobile communication device B receives the data as it is (see (3) in FIG. 12).

  Subsequently, the mobile communication device B confirms the transmission destination ID (destination) of the received data, and if the transmission destination ID designates another mobile communication device, it further specifies a relay ID. By counting, the number of relays of the data is confirmed. Here, the relay ID is an identification symbol such as a device ID that identifies a mobile communication device that relays transmitted data. For example, a mobile communication device that relays data is uniquely assigned to itself. Is added as a relay ID at the time of data relay.

  As a result of the confirmation, if the number of data relays has not reached the predetermined number, the device ID is added to the data as a relay ID and relayed without going through the network (( 4)). On the other hand, when the number of relays of the received data has reached a predetermined number, the relay of the data is stopped.

  Subsequently, the mobile communication device D located in a range in which communication with the mobile communication device B can be performed without going through the network receives this data relayed from the mobile communication device B without going through the network. Here, the mobile communication device D confirms the transmission destination ID (destination) of the received data, and as a result, if the transmission destination ID designates another mobile communication device, By counting the relay ID, the number of relays of the data is confirmed, and when the number of relays of the data has not reached the predetermined number, the received data is relayed as it is (see (5) in FIG. 12). ).

  And the mobile communication apparatus C located in the range which can communicate with the mobile communication apparatus D without via a network receives this data relayed from the mobile communication apparatus B without via a network. Here, the mobile communication device C confirms the transmission destination ID (destination) of the received data, and as a result, when the transmission destination ID does not designate another mobile communication device (that is, the destination is In the case of self), the received data is received as it is (see (6) in FIG. 12).

[Configuration of Mobile Communication Device (2) (Example 3)]
Next, the configuration (2) of the mobile communication device according to the third embodiment will be described. Note that the mobile communication device according to the third embodiment has basically the same configuration as the mobile communication device 20 shown in FIG. 2, but differs in the points described below.

  That is, the data receiving unit 22c of the communication control unit 22 confirms the transmission destination ID (destination) of the data received from the other mobile communication device, and as a result, the data transmission destination ID is the other mobile communication. If the device is to be designated, a relay command is sent to the data relay unit 22e together with the data so as to relay it without going through the network. However, even when the transmission destination ID designates another mobile communication device, when the number of relays of the received data has reached a predetermined number of relays, relay to the data relay unit 22a. The relay of the received data is stopped without sending the command.

  Specifically, when the data receiving unit 22c receives data transmitted from another mobile communication device using a function such as Bluetooth or infrared communication, the data receiving unit 22c sets a destination ID (destination) of the data. As a result, if the transmission destination ID (destination) of the data designates another mobile communication device, the data is further counted by counting the relay ID added to the data. (For example, if there are two relay IDs added to the data, the number of relays is two). As a result of the confirmation, if the number of data relays has reached a predetermined number (for example, 3 times), the data reception unit 22c does not send a relay command to the data relay unit 22e. Stop relaying received data.

  On the contrary, if the number of relays has not reached the predetermined number, the data receiving unit 22c sends a relay command together with the data to relay the received data as it is without going through the network. The data relay unit 22e that has sent to the unit 22e and received a relay instruction together with the data adds its own device ID as a relay ID to the data and relays it without going through the network.

  Note that the confirmation of the number of data relays is not limited to the confirmation by counting the additional number of relay IDs, but the number is incremented every time data is relayed in the mobile communication device, or predetermined every time relaying is performed. This flag may be added, and confirmation may be made by counting the flag.

[Processing of Mobile Communication Device (2) (Example 3)]
Next, the flow of the process (2) of the mobile communication device according to the third embodiment will be described with reference to FIG. FIG. 13 is a flowchart illustrating the flow of the process (2) of the mobile communication device according to the third embodiment. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when the data receiving unit 22c receives data from another mobile communication device without going through the network (Yes in step S1301), the data transmission destination ID (destination) is another mobile communication. It is confirmed whether or not the device is designated (step S1302).

  As a result of the confirmation, when the data transmission destination ID designates another mobile communication device (Yes at step S1302), the data receiving unit 22c is further added to the data. The number of data relays is confirmed by counting the relay ID (for example, if there are two relay IDs added to the data, the number of relays is two). In order to relay the data as it is without going through the network, a relay command is sent to the data relay unit 22e together with the data, and the data relay unit 22e that receives the relay command together with the data further counts the relay ID. Thus, the number of data relays is confirmed (for example, if there are two relay IDs added to the data, the number of relays is two).

  As a result of the confirmation, if the number of data relays has reached a predetermined number (for example, 3 times) (Yes at step S1303), the data reception unit 22c instructs the data relay unit 22e to perform relaying. The relay of the received data is stopped without sending (step S1304). On the contrary, if the number of data relays has not reached the predetermined number of relays (No at step S1303), the data receiving unit 22c relays the received data as it is without going through the network. The data relay unit 22e sends a relay command together with the data to the data relay unit 22e, and receives the relay command together with the data, adds its own device ID as a relay ID to the data and relays it without going through the network. (Step S1305).

  Here, returning to the description of step S1302, if the destination ID (destination) of the received data does not specify another mobile communication device (No at step S1302), the data should be received as it is. The incoming call processing command is sent to the incoming call processing unit 22d together with the data, and the incoming call processing unit 22d receiving the incoming call processing command along with the data receives the data as it is (step S1306). In addition, when the received data is the same as the data that has already undergone the incoming call processing, the data receiving unit 22c does not send an incoming call processing command to the incoming call processing unit 22d and does not receive the incoming call. Good.

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Effect of Example 3]
As described above, according to the third embodiment, when the mobile communication device receives the same data as the relayed data, the mobile communication device stops transmitting the data. Can be prevented.

  Further, according to the third embodiment, the mobile communication device stops transmitting data when the number of times the received data has been relayed has reached a predetermined number of times. Can be prevented by a simple processing procedure.

  By the way, in the above-described embodiment, the case where the data generated for each group member's destination is transmitted has been described. However, the present invention is not limited to this, and one piece of data destined for all the group members. May be generated and transmitted. Therefore, in the following, as a fourth embodiment, a case will be described in which a mobile communication device mounted on a vehicle generates and transmits one data addressed to all group members.

  Since the configuration of the mobile communication device in this case is basically the same as that of the above embodiment, the mobile body different from that described in the above embodiment will be described below with reference to FIGS. The outline, configuration, and processing flow of the communication apparatus will be described in order, and finally the effects of the fourth embodiment will be described. FIG. 14 is a diagram for explaining the outline of the mobile communication device according to the fourth embodiment. FIG. 15 is a flowchart illustrating the flow of data transmission processing of the mobile communication device according to the fourth embodiment. 16 is a flowchart illustrating a flow of data relay processing of the mobile communication device according to the fourth embodiment.

[Outline of Mobile Communication Device (Example 4)]
First, the outline of the mobile communication device according to the fourth embodiment will be described with reference to FIG. As shown in the figure, the owners of mobile communication devices A, B, and C belong to a predetermined group, and mobile communication devices A, B, and C are group members within the group to which each belongs. Is stored in a group list (for example, (A, B, C)). In addition, the mobile communication device A shown in the figure can communicate with other mobile communication devices B in the group via a network (for example, communication using a function such as Bluetooth or infrared communication). The mobile communication devices C are in a positional relationship that cannot communicate with other mobile communication devices C in the group via the network, and the mobile communication devices B and C and other mobile communication devices D outside the group. Are in a positional relationship in which communication is not possible via a network.

  Then, the mobile communication device A transmits predetermined data (for example, image data and audio data) to the other mobile communication devices B and C in the group without going through the network. Specifically, the mobile communication device A, based on the stored group list and predetermined data, the transmission source ID (for example, A), the transmission destination ID (for example, B and C), the predetermined data, One piece of outgoing data that is addressed to all of the group members including the message is generated and sent without going through the network. In other words, the amount of outgoing data is reduced as compared with the case where a plurality of outgoing data for each group member is generated and transmitted.

  The mobile communication device B that is in a positional relationship capable of communicating with the mobile communication device A without going through the network receives the data transmitted from the mobile communication device A without going through the network. Then, the mobile communication device B confirms the destination of the received data, and receives or relays the data.

  Specifically, as a result of confirming the destination of the received data, if the destination includes the own device ID, the mobile communication device B receives and relays the received data. On the other hand, if the destination of the received data does not include itself, only the received data is relayed. That is, in the case shown in FIG. 14, the mobile communication device B receives and relays data, since itself (B) is included in the destination (B / C) of the received data.

  The mobile communication device D in a positional relationship that can communicate with the mobile communication device B without going through the network receives the data relayed from the mobile communication device B without going through the network. Similarly to the above, the mobile communication device D confirms the destination of the received data and performs incoming or relaying of data. That is, in the case shown in FIG. 14, the mobile communication device D does not include itself (B) in the destination (B / C) of the data received from the mobile communication device B without going through the network. Relay without receiving incoming calls.

  The mobile communication device C that is in a positional relationship capable of communicating with the mobile communication device D without going through the network receives the data relayed from the mobile communication device D without going through the network. Similarly to the above, the mobile communication device C confirms the destination of the received data and performs incoming or relaying of data. That is, in the case shown in FIG. 14, the mobile communication device C confirms the destination (B / C) of the data received from the mobile communication device B without going through the network, and the destination includes self (C). So incoming and relaying data.

[Configuration of Mobile Communication Device (Example 4)]
Next, the configuration of the mobile communication device according to the fourth embodiment will be described. Note that the mobile communication device according to the fourth embodiment has basically the same configuration as the mobile communication device shown in FIG. 2, but differs in the points described below.

  That is, the transmission processing unit 22a of the communication control unit 22 receives predetermined data (for example, image data and audio data) from the user via the display 11 and a destination (for example, mobile communication devices B and C) of the predetermined data. ) Is received, based on the group list stored in the group list storage unit 21a and the predetermined data stored in the data storage unit 21b, the transmission source ID (for example, A) and the transmission destination ID (for example, , B, and C) and one data for sending to all the group members including the predetermined data.

  In addition, the data receiving unit 22c of the communication control unit 22 confirms the transmission destination ID (destination) of data received from another mobile communication device, and as a result, the data reception unit 22c itself (for example, the data transmission destination ID) , Device ID) is sent, the data and the incoming processing command are sent to the incoming processing unit 22d and the data and the relay command are sent to the data relay unit 22e in order to receive and relay the data. Send. On the other hand, if the transmission destination ID of the received data does not include itself, a relay command is sent to the data relay unit 22e together with the data in order to relay only the data.

  If the received data is the same as the data that has already sent the incoming call processing command to the incoming call processing unit 22d, the data receiving unit 22c of the communication control unit 22 does not send the incoming call processing command, May not be received.

[Data Transmission Processing of Mobile Communication Device (Example 4)]
Subsequently, a flow of data transmission processing of the mobile communication device according to the fourth embodiment will be described with reference to FIG. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when there is an instruction to transmit data (image data or the like) from the user (Yes at Step S1501), the transmission processing unit 22a reads the group list from the group list storage unit 21a (Step S1502).

  Subsequently, the transmission processing unit 22a reads data for which a transmission instruction has been issued from the data storage unit 21b (step S1503). Then, based on the read group list and data, the transmission processing unit 22a generates one transmission data that is addressed to all the group members who have been instructed to transmit by the user (step S1504). For example, the transmission processing unit 22a generates one transmission data addressed to both the group members B and C and sends a transmission command to the data transmission unit 22b together with the transmission data. The data transmitting unit 22b that has received the transmission command together with the transmission data transmits the transmission data without going through the network (step S1505).

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Data Relay Processing of Mobile Communication Device (Example 4)]
Subsequently, a flow of data relay processing by the mobile communication device according to the fourth embodiment will be described with reference to FIG. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when data is received from another mobile communication device via the network (Yes in step S1601), the data receiving unit 22c includes itself in the transmission destination ID (destination) of the data. (Step S1602).

  As a result of the confirmation, when self is included in the transmission destination ID (destination) of the data (Yes at step S1602), the data receiving unit 22c receives the data and the incoming call in order to receive and relay the data. The processing command is sent to the incoming processing unit 22d, and the data and relay command are sent to the data relay unit 22e. The incoming processing unit 22d that receives the incoming processing command performs incoming of the data and sends the relay command. The received data relay unit 22e relays the data as it is without using a network using a function such as Bluetooth or infrared communication (step S1603).

  Here, returning to the description of step S1602, if self is not included in the destination ID (destination) of the received data (No at step S1602), the data receiving unit 22c only relays the data. In order to do so, a relay command is sent to the data relay unit 22e together with the data, and the data relay unit 22e that receives the relay command uses the function such as Bluetooth or infrared communication to transmit the data to the network. It relays without going through (step S1604).

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Effect of Example 4]
As described above, according to the fourth embodiment, since this mobile communication device transmits one data addressed to all of the group members, data for transmission addressed to each of the group members. The amount of data transmission can be reduced compared to the case where a plurality of data are generated and transmitted respectively.

  By the way, in the above-described embodiment, the case where the mobile communication device that has received data destined for all of the groups always relays the data has been described, but the present invention is not limited to this, In this case, data relay may be stopped. Therefore, in the following, as a fifth embodiment, a case where data relay is controlled in a mobile communication device mounted on a vehicle will be described.

The configuration of the mobile communication device in this case is basically the same as the above embodiment,
Hereinafter, outlines (1) and (2), configurations (1) and (2) of a mobile communication device different from those described in the above embodiment, a flow of processing (FIG. 17 to FIG. 20) 1) and (2) will be described in order, and finally the effect of the fifth embodiment will be described. FIG. 17 is a diagram for explaining the outline (1) of the mobile communication device according to the fifth embodiment, and FIG. 18 is a flowchart showing the flow of the process (1) of the mobile communication device according to the fifth embodiment. FIG. 19 is a diagram for explaining an outline (1) of the mobile communication device according to the fifth embodiment, and FIG. 20 is a flow of processing (2) of the mobile communication device according to the fifth embodiment. It is a flowchart which shows.

[Outline of Mobile Communication Device (1) (Example 5)]
First, the outline | summary (1) of the mobile communication apparatus which concerns on Example 5 is demonstrated using FIG. As shown in the figure, the owners of mobile communication devices A, B, and C belong to a predetermined group, and mobile communication devices A, B, and C are group members within the group to which each belongs. Is stored in a group list (for example, (A, B, C)). In addition, the mobile communication device A shown in the figure can communicate with other mobile communication devices B in the group via a network (for example, communication using a function such as Bluetooth or infrared communication). The mobile communication devices C are in a positional relationship that cannot communicate with other mobile communication devices C in the group via the network, and the mobile communication devices B and C and other mobile communication devices D outside the group. Are in a positional relationship in which communication is not possible via a network.

  Then, the mobile communication device A transmits predetermined data (for example, image data and audio data) to the other mobile communication devices B and C in the group without going through the network. Specifically, the mobile communication device A includes a group including a transmission source ID (for example, A), a transmission destination ID (for example, B and C), and predetermined data based on the stored group list. One transmission data addressed to all members is generated and transmitted without going through the network (see (1) in FIG. 17).

  Next, each mobile communication device that receives the data transmitted from the mobile communication device without going through the network can receive or relay the received data, or stop relaying based on the destination of the received data and the incoming ID. Control. Here, the incoming ID is information for identifying the device that has received the data. For example, the incoming ID is a device ID that is uniquely assigned to each group member device. Added to the received data.

  Here, the above-described control of incoming data reception, relay, or relay stop will be described in detail. When the destination of the received data is all included in the incoming ID, the relay of the received data is stopped. . That is, it is intended to prevent unnecessary data (data received at all destinations) from being relayed. On the other hand, if the destination of the received data is not all included in the incoming call ID, it is further checked whether or not self (device ID) is included in the destination. As a result, when self is included, the received data is received and relayed. On the other hand, if the received data does not include itself as a destination, the received data is relayed as it is.

  That is, in FIG. 17, the mobile communication device B that is in a positional relationship that can communicate with the mobile communication device A without going through the network includes all destinations of data received from the mobile communication device A in the incoming ID. The incoming data does not exist (there is no incoming ID yet) and the destination includes self (device ID), so the received data is received and relayed (see (2) and (3) in FIG. 17). Here, when the mobile communication device B relays the data, the mobile communication device B adds its own device ID (B) as the incoming call ID to the data to be relayed (see (3) in FIG. 17).

  In addition, the mobile communication device D that is in a positional relationship capable of communicating with the mobile communication device B without going through the network does not include all the destinations of the data received from the mobile communication device B in the incoming call ID. Since the device ID is not included in the destination, the received data is relayed as it is ((4) in FIG. 17).

  In addition, in the mobile communication device C that is in a positional relationship capable of communicating with the mobile communication device D without going through the network, the destination of the data received from the mobile communication device D is not included in the incoming call ID. Since the device ID is included in the destination, the received data is received and relayed (see (5) and (6) in FIG. 17). Although not shown in FIG. 17, the mobile communication device that has received the data relayed from the mobile communication device C includes the destination of the received data in the incoming call ID (see FIG. 17). (Refer to (6)), the relay of the received data is stopped.

[Configuration of Mobile Communication Device (1)]
Next, the configuration (1) of the mobile communication device according to the fifth embodiment will be described. The configuration of the mobile communication device according to the fifth embodiment is basically the same as that of the mobile communication device shown in FIG. 2, but differs in the points described below.

  That is, the data reception unit 22c of the communication control unit 22 controls the reception, relay, or relay stop of received data based on the destination (transmission destination ID) of the data received from another mobile communication device and the incoming ID. To do. Specifically, it is confirmed whether or not the destination of the received data is all included in the incoming call ID. If all of the destinations are included, the data receiving unit 22c instructs the data relay unit 22e to perform relaying. Stops relaying received data without sending

  On the other hand, when the destination of the received data is not included in the incoming call ID, the data receiving unit 22c further checks whether or not the destination (device ID) is included in the destination. As a result, when the self is included, the data receiving unit 22c sends the data and the incoming call processing command to the incoming call processing unit 22d to receive and relay the received data, and the data and relay command Is sent to the data relay unit 22e. Received data is received and relayed. In this case, the data relay unit 22e that has received the relay instruction adds its own device ID as the incoming call ID and relays the received data.

  On the contrary, if the destination of the received data does not include itself, the data receiving unit 22c sends the data and a relay instruction to the data relay unit 22e so as to relay the data as it is. . In this case, the data relay unit 22e that receives the relay command relays the received data without adding its own device ID as the incoming ID.

[Processing of Mobile Communication Device (1) (Embodiment 5)]
Subsequently, the flow of the process (1) of the mobile communication device according to the fifth embodiment will be described with reference to FIG. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when data is received from another mobile communication device without going through the network (Yes in step S1801), the data receiving unit 22c includes all destinations of the received data in the incoming ID. It is confirmed whether or not (step S1802). As a result, when the destination of the received data is all included in the incoming ID (Yes at step S1802), the data receiving unit 22c does not send a relay command to the data relay unit 22e, and receives the received data. Is stopped (step S1803).

  On the other hand, when the destination of the received data is not all included in the incoming ID (No at step S1802), the data receiving unit 22c further includes self (device ID) in the destination. It is confirmed whether or not (step S1804). As a result, if the destination of the received data includes itself (Yes at step S1804), the data receiving unit 22c sends the received data and an incoming processing command to the incoming processing unit 22d in order to receive and relay the received data. The data and the relay command are sent to the data relay unit 22e. The incoming processing unit 22d that receives the incoming processing command performs incoming processing of the received data, and the data relay unit 22e that receives the relay command Then, relaying is performed by adding its own device ID to the received data as the incoming ID (step S1805).

  On the other hand, if the destination of the received data does not include itself (No at step S1804), the data receiving unit 22c sends the data and a relay instruction to the data relay unit 22e so as to relay the data as it is. The data relay unit 22e that has received the sending and relay command relays the data as it is (step S1806).

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Effect of Example]
As described above, according to the fifth embodiment, this mobile communication measure transmits one data addressed to all the members of the group, and when receiving and relaying the received predetermined data, When the incoming information for identifying the mobile communication device is added and relayed, and the destination of the predetermined data is all included in the incoming information attached to the data, the data Therefore, it is possible to prevent unnecessary data (that is, data that has already arrived at all destinations) from being transmitted.

  In the fifth embodiment, when the destination of the received data is not included in the incoming ID, and the self (device ID) is included in the destination, the incoming and relaying of data is performed. However, the present invention is not limited to this, and when the received data is received, the destination of the received data is all included in the incoming ID (that is, the self of the received data is In the case of the last callee included in the destination), data reception and relay stop may be performed. This is intended to prevent unnecessary data (that is, data that has already arrived at all destinations) from being relayed.

[Outline of Mobile Communication Device (2) (Example 5)]
By the way, in the above-described embodiment, the case where the incoming data, the relay, or the relay stop of the data is controlled based on the destination of the received data and the incoming ID is described. However, the present invention is not limited to this, and the received data Data relay may be controlled by deleting the destination each time an incoming call is received. Therefore, hereinafter, a case where data relay is controlled in a mobile communication device mounted on a vehicle will be described.

  First, the outline (2) of the mobile communication device according to the fifth embodiment will be described with reference to FIG. As shown in the figure, as shown in the figure, each owner of the mobile communication devices A, B and C belongs to a predetermined group, and each mobile communication device has a group member within the group. An enumerated group list (for example, (A, B, C)) is stored. In addition, the mobile communication device A shown in the figure can communicate with other mobile communication devices B in the group via a network (for example, communication using a function such as Bluetooth or infrared communication). The mobile communication devices C are in a positional relationship that cannot communicate with other mobile communication devices C in the group via the network, and the mobile communication devices B and C and other mobile communication devices D outside the group. Are in a positional relationship in which communication is not possible via a network.

  Then, the mobile communication device A transmits predetermined data (for example, image data and audio data) to the other mobile communication devices B and C in the group without going through the network. Specifically, the mobile communication device A includes a group including a transmission source ID (for example, A), a transmission destination ID (for example, B and C), and predetermined data based on the stored group list. One transmission data addressed to all members is generated and transmitted without going through the network (see (1) in FIG. 18).

  Next, each mobile communication device that receives data transmitted from the mobile communication device without going through the network controls data arrival, relay, and relay stop based on the destination of the received data. Specifically, if the received data includes the self (device ID) in the destination, the data is received and the data is relayed by deleting the self from the destination. On the other hand, if the destination does not include itself, the received data is relayed as it is.

  That is, in FIG. 19, the mobile communication device B that is in a positional relationship that can communicate with the mobile communication device A without going through the network includes itself as the destination of the data received from the mobile communication device A. The received data is received and the data is relayed by deleting itself from the destination (see (2) and (3) in FIG. 19).

  In addition, since the mobile communication device D that is in a positional relationship capable of communicating with the mobile communication device B without going through the network does not include itself in the destination of the data received from the mobile communication device B, the received data is used as it is. Relay ((4) in FIG. 19).

  Also, the mobile communication device C that is in a positional relationship capable of communicating with the mobile communication device D without going through the network receives the received data because the destination of the data received from the mobile communication device D is included in itself. At the same time, it deletes itself from the destination and relays it. In this case, since there is no destination of data to be relayed, only the incoming call is performed and the relay is stopped (see (5) in FIG. 19). That is, it is intended to prevent unnecessary data (that is, data that has already arrived at all destinations) from being relayed.

[Configuration of Mobile Communication Device (2)]
Next, the configuration (2) of the mobile communication device according to the fifth embodiment will be described. The configuration of the mobile communication device according to the fifth embodiment is basically the same as that of the mobile communication device shown in FIG. 2, but differs in the points described below.

  That is, the data receiving unit 22c of the communication control unit 22 confirms the destination of data received from another mobile communication device, and if the destination includes self (device ID), the data is received. In addition, in order to relay, the data and the incoming call processing command are sent to the incoming call processing unit 22d, and the data and the relay command are sent to the data relay unit 22e. In this case, the data relay unit 22e that has received the relay command deletes itself from the destination of the received data and performs the relay. Note that the data relay unit 22e stops relaying the received data when there are no more destinations as a result of deleting the destination of the received data.

  On the other hand, if the destination of data received from another mobile communication device does not include itself (device ID), the data receiving unit 22c sends the data and a relay command to the data relay to relay the received data. Sent to the unit 22e. In this case, the data relay unit 22e that receives the relay command relays the received data as it is.

[Processing of Mobile Communication Device (2) (Example 5)]
Subsequently, the flow of the process (2) of the mobile communication device according to the fifth embodiment will be described with reference to FIG. Note that the processing described below is repeatedly executed during operation of the mobile communication device.

  As shown in the figure, when data is received from another mobile communication device without going through the network (Yes in step S2001), the data receiving unit 22c includes itself (device ID) in the destination of the received data. Whether or not (step S2002).

  As a result, if the destination of the received data includes itself (Yes at step S2002), the data receiving unit 22c sends the data and an incoming processing command to the incoming processing unit 22d in order to receive and relay the data. The data and the relay command are sent to the data relay unit 22e, and the incoming processing unit 22d that receives the incoming processing command performs the incoming processing of the received data and receives the relay command. 22e deletes itself from the destination of the received data and relays it (step S2003). Note that the data relay unit 22e stops relaying the received data when there are no more destinations as a result of deleting the destination of the received data.

  On the other hand, if the destination of the received data does not include itself (No at step S2002), the data receiving unit 22c sends the data and a relay instruction to the data relay unit 22e in order to relay the received data. The data relay unit 22e that has received the sending and relay command relays the received data as it is (step S2004).

  In addition, although demonstrated above as a process by each functional block which the microcomputer which is the communication control part 22 implement | achieves, an actual process is performed by a microcomputer.

[Effect of Example 5]
As described above, according to the fifth embodiment, this mobile communication device transmits one data addressed to all of the group members, and when the received predetermined data address is self, Since the specified data is received and sent by deleting itself from the destination, when all destinations arrive, the destination disappears and the transmission is stopped, and unnecessary data (that is, all destinations already received) is transmitted. Can be prevented.

  By the way, in the above-described embodiment, the center (server device) may accept a member who wants to join a predetermined group. Therefore, in the following sixth embodiment, a case where a person who wants to join a group configured between mobile communication devices mounted on a vehicle is accepted at the center will be described with reference to FIGS. FIG. 21 is a diagram for explaining the outline of acceptance recruitment reception for a group according to the sixth embodiment, and FIG. 22 is a diagram illustrating a display example of a group member recruitment screen according to the sixth embodiment. These are figures which show the example of a display of the application notification which concerns on Example 6, and FIG. 24 is a figure which shows the example of a display of the admission reception notification which concerns on Example 6. FIG.

  As shown in FIG. 21, when there is access to the center (server device) from the mobile communication device C (see (1) in FIG. 21), the center is illustrated in FIG. A recruitment screen for a predetermined group is transmitted (see (2) in FIG. 21). When the user of the mobile communication device C that has received the recruitment screen designates a group that he / she wants to join with an icon (“Apply”) in the recruitment screen, the mobile communication device C, for example, as illustrated in FIG. An application notification is automatically generated, and the application notification is transmitted to the center.

  The center stores a group list (for example, (A / B)) for a group (for example, group DL) that the user of mobile communication device C desires to join. When an application notification is received from the mobile communication device C, a new group list (for example, (A, B, C)) is generated (see (4) in FIG. 21). Then, the newly generated group list is transmitted to the mobile communication devices of the existing group members (A and B), and for the user of the mobile communication device C who is a member who wishes to join, for example, FIG. A membership admission notification and a group list are transmitted as exemplified in (see (5) in FIG. 21).

  In this way, another communication device that can communicate with the mobile communication device accepts a member who wishes to join a predetermined group, generates a group list that enumerates the accepted group members, Since the mobile communication device stores the generated group list, the group member does not need to accept membership in the group at the mobile communication device (for example, a server device installed at the center or the like). Can be formed.

  In the above-described embodiment, the case where the user is always allowed to join the predetermined group has been described. However, the present invention is not limited to this, and the center (server device) allows the user to join the predetermined group. You may make it admit admission after judging whether or not.

  In this way, this mobile communication device determines whether or not admission is accepted for those who wish to join a group, and generates a group list for those who wish to join at the center. Group can be formed.

  Further, in the above embodiment, as information used for determining whether or not to admit a predetermined group, for example, information received from the applicant (for example, a group member who has already formed a group by the applicant) Received from the mobile communication device of the applicant (for example, navigation information such as destination, address, vehicle type, manufacturer of the navigation device, etc.) The membership may be determined at the center using any one or a plurality of information paths (for example, the number of times of relaying information).

  As described above, the mobile communication device includes one or more of information received from the applicant, information acquired from the mobile communication device of the applicant, and a route of information sent from the applicant. Based on the above, it is determined in the center whether or not the admission applicant is permitted to join, so that it becomes possible to select the members who join the group in detail from various viewpoints.

  By the way, in the above-described embodiment, a case has been described in which a center (server device) accepts a member who wants to join a predetermined group. However, the present invention is not limited to this, and the mobile communication device You may make it accept the candidate who joins a group. Therefore, in the following seventh embodiment, a case where a mobile communication device mounted on a vehicle accepts an applicant for joining a group will be described with reference to FIGS. 25 and 26. FIG. 25 is a diagram for explaining an outline of acceptance reception for joining a group according to the seventh embodiment, and FIG. 26 is a diagram illustrating a display example of a group member recruiting screen according to the seventh embodiment.

  As illustrated in FIG. 25, the mobile communication device A transmits a recruitment screen as illustrated in FIG. 26 without using the network (see (1) in FIG. 25). In addition, before transmitting the recruitment screen as data, the mobile communication measure A detects in advance other mobile communication devices that can receive the data to be transmitted, and transmits the detected device as a destination. The owner of the mobile communication device C that has received the recruitment screen inputs, for example, a password previously obtained from a group member who already belongs to the group that wishes to join and enters the recruitment screen at a predetermined location. When an icon in the screen (“Apply”) is designated, the mobile communication device C automatically generates and sends an application message addressed to the mobile communication device A, for example ((2) in FIG. 25). reference).

  The mobile communication device A stores a group list (for example, (A / B)) for a group (for example, a group DL) that the user of the mobile communication device C desires to join. Then, when an application message is received from the mobile communication device C, a new group list (for example, (A, B, C)) is generated (see (3) in FIG. 25). Then, the newly generated group list is transmitted to the mobile communication device of the existing group member (B), and the admission acceptance notification and the group list are transmitted to the mobile communication device C of the applicant for membership. (See (4) in FIG. 25).

  As described above, the mobile communication device accepts a member who wishes to join a predetermined group, generates a group list enumerating the accepted group members, and stores the generated group list. Without waiting for the formation of a group by the center or the like, it becomes possible to accept membership in the group by the mobile communication device and form a group member.

  Further, in the above-described embodiment, a case has been described in which admission to a predetermined group is always permitted. However, the present invention is not limited to this, and whether or not admission to a group is permitted in a mobile communication device. You may make it admit admission after judging.

  In this way, this mobile communication device determines whether or not admission is permitted for those who wish to join a group, and generates a group list for those who wish to join, thus forming a group selected by admission determination. It becomes possible to do.

  Also, in the above embodiment, as information used to determine whether or not admission to a predetermined group is permitted, information received from an applicant for membership (for example, obtained from a group member who has already formed a group. A password unique to the group), information obtained from the mobile communication device of the applicant (for example, navigation information such as destination, address, vehicle type, manufacturer of navigation device), information sent from the applicant Any one or a plurality of routes (for example, the number of times of relaying information) may be used.

  As described above, the mobile communication device includes one or more of information received from the applicant, information acquired from the mobile communication device of the applicant, and a route of information sent from the applicant. Based on the above, it is determined whether or not the admission applicant is permitted to join, so that it becomes possible to select the members who join the group in detail from various viewpoints.

  In the above embodiment, the case has been described in which data generated for recruiting group members (for example, recruitment screens) is voluntarily transmitted from the mobile communication device to accept membership in the group. The invention is not limited to this. For example, information relating to a group (for example, group list, group ID, group name, group purpose, etc.) stored in the storage unit of the mobile communication device is voluntarily You may make it public and accept the membership for the public group.

  In addition to voluntarily publishing information related to the group stored in the storage unit, after receiving a request for publishing information related to the group from another mobile communication device, the information is disclosed to the group. May be accepted. Therefore, in the following, with reference to FIG. 27, the mobile communication device in the case where the information disclosure request relating to the group is received from another mobile communication device and then the information relating to the group is disclosed and the membership to the group is accepted Will be described. FIG. 27 is a diagram for explaining an outline (2) of acceptance of recruitment to a group according to the seventh embodiment.

  For example, as shown in FIG. 27, the mobile communication device A stores information related to a plurality of groups. In addition, the mobile communication device X and the mobile communication device Y have previously detected a device capable of receiving data, and when the mobile communication device A is detected, the mobile communication device A receives information on the group. Request publication. Upon receiving this request, the mobile communication device A transmits information related to the stored group (for example, group list, group ID, group name, group purpose, etc.) to the mobile communication devices X and Y. And make it public. Then, the mobile communication device A accepts the membership request from the mobile communication devices X and Y to the disclosed group.

  In this way, this mobile communication device publishes information related to the group stored in the group list and accepts membership in the published group, thus encouraging membership in the group via the mobile communication device. It becomes possible to do.

  Further, in the above-described embodiment, the case where there is a request for information disclosure related to a group is disclosed to anyone unconditionally. However, the present invention is not limited to this, and predetermined mobile communication You may make it open | release the information which concerns on the other group to which the said mobile body passing apparatus belongs only to the group member of the group to which an apparatus belongs. Therefore, hereinafter, the mobile communication apparatus in this case will be described. FIG. 28 is a diagram for explaining an outline (3) of acceptance of recruitment to a group according to the seventh embodiment.

  For example, as shown in FIG. 28, the mobile communication device B belonging to the groups 1 and 3 stores a group list for the groups 1 and 3. Then, the mobile communication device B, with respect to the group members A and B of the group 1 to which the mobile communication device B belongs, relates to the group 3 that is another group to which the mobile communication device B belongs (for example, a group list or a group ID, group name, group purpose, etc.) are disclosed (see (1) in FIG. 28). On the other hand, when accepting the disclosure of the information related to group 3, mobile communication device A sends a request for membership to the mobile communication device when it wishes to join group 3. Then, the mobile communication device B accepts the desire to join the group 3 from the mobile communication device A (see (2) in FIG. 28).

  In this way, since this mobile communication device discloses information related to other groups to which the mobile device belongs only to the members of the group to which the mobile device belongs, It will only be possible to give other groups an opportunity to join.

  The mobile communication devices according to the first to seventh embodiments have been described so far, but the present invention may be implemented in various different forms other than the above-described embodiments.
