Description

  The present invention relates to an information transfer device, an information transfer system, an information transfer method, and an information transfer control program, and more particularly to an information transfer device, an information transfer system, an information transfer method, and an information transfer capable of reliably transferring information to all transfer destinations. It relates to the control program.

  Generally, by designating a plurality of transmission destination addresses, the same data can be transmitted from a certain communication terminal to a plurality of other communication terminals with a single transmission operation. Thus, transmitting information to a plurality of transmission destinations by one transmission operation is called “broadcast transmission”.

  The broadcast transmission seems to be performed by only one transmission to the user of the communication terminal that is the broadcast transmission source. However, in practice, a predetermined communication control device existing between the broadcast transmission source and the broadcast transmission destination communication terminal sets the transmission destination address for each communication terminal of the transmission destination, and divides it into multiple times individually. Sending information.

  For example, with respect to transmission of e-mail using a mobile phone, a “broadcast mail function” provided by a telecommunications carrier may be used. The broadcast mail function is a function that can send an e-mail to a plurality of destinations by one transmission operation. The broadcast mail function is usually realized by switching addresses for each destination mobile phone by a communication control device on a communication network managed by a communication carrier and transmitting them individually. That is, a communication control server such as a circuit switched network or a packet switched network sets the broadcast transmission destination addresses set in the broadcasted e-mail one by one in the same e-mail. Then, the electronic mail is repeatedly transmitted for each individual destination. Further, a reception response is transmitted from each transmission destination. Therefore, in the broadcast mail, if there are a large number of transmission destinations, radio resources are occupied and there is a possibility of causing congestion and the like. As for the communication fee, for the user, a packet fee may be added corresponding to the number of characters (destination information amount) of the destination address, or a transmission fee proportional to the number of destinations may be required. . Furthermore, the number of transmission destinations that can be broadcast may be limited.

  As described above, broadcast transmission has problems such as an increase in communication charges, occupation of radio resources, and limitation on the number of transmission destinations. Therefore, a technique that can solve such a problem is desired.

  By the way, there is a technique for transferring a call or information from a communication terminal to a communication terminal around the communication terminal (see, for example, Patent Documents 1 and 2). When receiving the emergency information, the portable terminal device of Patent Literature 1 transfers the emergency information to surrounding portable terminal devices. When the mobile communication terminal of Patent Document 2 detects an incoming call, the mobile communication terminal transfers the call to a pre-registered terminal among peripheral mobile communication terminals.

  When the techniques of Patent Documents 1 and 2 are applied, it is possible to transfer the same information to another communication terminal via one communication terminal among a plurality of communication terminals.

  Therefore, when performing broadcast transmission, a method of improving the efficiency of broadcast transmission by transferring information via a certain communication terminal can be considered.

JP 2003-244068 A (page 2-3, FIG. 1) JP 2007-81498 A (page 9, FIG. 9)

  With the technique of Patent Document 1, information can be transferred to a plurality of portable terminals. However, the purpose of the technique of Patent Document 1 is to develop emergency information. Therefore, the object can be achieved if emergency information can be transferred to as many portable terminals as possible. And since it is not necessary to limit the transmission destination of information on the property of information, it is not a problem whether the transfer of the information to a specific portable terminal was completed. Therefore, there is no means for designating the transmission destination.

  Since the technique of Patent Document 1 has the above-described features, a problem occurs when the technique of Patent Document 1 is applied to broadcast transmission. That is, even if information is not transmitted to some of the mobile terminals set as the broadcast transmission destination, the technique of Patent Document 1 does not perform any measures. Therefore, when the broadcast transmission source performs the broadcast transmission, in spite of recognizing that transmission to all the broadcast transmission destinations has been completed, in fact, some of the transmission destinations have information. There may be a problem of not reaching. Therefore, the technique of Patent Document 1 is not suitable for a use in which the information is surely transmitted to all transmission destinations by applying to the broadcast transmission.

  Even using the technique of Patent Document 2, it is possible to transfer information. However, the technique of Patent Document 2 is a technique for having a user of another mobile phone answer instead when the user of the mobile phone that has received the call cannot respond. Therefore, means for registering a group as a plurality of transfer destination candidates is provided. However, the incoming call is actually notified only to one mobile phone selected from the group. Therefore, transfer of the same information to a plurality of communication terminals, such as broadcast transmission, is outside the scope of the technique of Patent Document 2, and cannot be realized with the technique of Patent Document 2.

As described above, the techniques of Patent Documents 1 and 2 cannot be applied to broadcast transmission, or even when applied, there is a problem that information cannot be reliably transmitted to all broadcast transmission destinations. .

(First embodiment)
A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of the information transfer apparatus 100 according to the first embodiment. The information transfer apparatus 100 includes a first communication unit 101, a second communication unit 102, a storage unit 103, and a transfer control unit 104.

  The first communication unit 101 receives first information 111 including information to be transferred (hereinafter referred to as “transfer information”), and outputs transfer information 112. The first information 111 is transmitted from a communication device (not shown) that is a transmission source of the transfer information 112.

  The storage unit 103 stores a preset transfer destination to which the transfer information 112 is to be transferred. Then, the storage unit 103 outputs transfer destination identification information 113 that designates a transfer destination.

  The second communication unit 102 generates second information 114 including transfer information 112. Then, the second communication unit 102 transmits the second information 114 to the transmission destination specified by the transfer destination identification information 113. When there are a plurality of transfer destinations, the second information 114 may be transmitted by designating a plurality of transfer destinations at the same time. Alternatively, one transfer destination may be designated, and the second information 114 may be transmitted sequentially in a plurality of times.

  Then, the second communication unit 102 receives the reception completion notification 115 from the transfer destination, adds the transfer destination identification information, and outputs the transfer completion notification 116. The transfer completion notification 116 indicates a transfer destination for which transfer has been completed among all transfer destinations.

  After the transmission of the second information 114, the transfer control unit 104 determines a transfer destination for which transfer has not been completed. At this time, the transfer control unit 104 refers to the transfer destination identification information 113 in addition to the transfer completion notification 116. Then, when a transfer destination for which transfer has not been completed (hereinafter referred to as “non-delivery transfer destination”) is found, a retransmission request 117 designating identification information of the non-delivery transfer destination is output and sent to the second communication unit 102. Instructs retransmission of the second information.

  The operation of the information transfer apparatus 100 described above can be realized by software processing using a central processing unit (hereinafter referred to as “CPU”, not shown in FIG. 1) built in the information transfer apparatus 100. Is possible. FIG. 2 is a flowchart showing the operation of the information transfer apparatus 100 processed by the CPU.

  First, the CPU receives first information (step S11) and generates second information from the first information (step S12). Then, the CPU reads the transfer destination identification information (step S13) and transmits the second information to the transfer destination (step S14).

  Next, the CPU confirms reception of a reception completion notification from the transfer destination (step S15). When reception of reception completion notifications from all transfer destinations is confirmed, the CPU ends the process. If reception of the reception completion notification is not confirmed, the CPU retransmits the second information to a non-delivery transfer destination that is a transfer destination for which the reception completion notification is not confirmed (step S16). The process of S16 is repeated until reception of reception completion notifications from all transfer destinations is confirmed.

  Instead of repeating retransmission until reception of reception completion notifications from all transfer destinations is confirmed, an appropriate timeout time may be set. That is, if reception of a reception completion notification from the transfer destination is not confirmed even after the timeout time is exceeded, it may be determined that transfer is impossible. In that case, the transfer information transmission source communication device may be notified of the transfer completion or the transfer destination identification information for which transfer has not been completed.

  As described above, the information transfer apparatus according to the present embodiment determines a transfer destination for which information transfer has not been completed, and retransmits the information to the transfer destination. Therefore, there is an effect that information can be reliably transferred to all transfer destinations.

In addition, when the communication method used by the second communication unit 102 is a so-called “short-range wireless communication method”, the occupation of wireless resources is limited to a narrow range. Therefore, even if there are a plurality of information transfer destinations, the influence of radio resource occupation can be reduced as much as possible. The “short-range wireless communication system” here is a wireless LAN (Local Area Network), Bluetooth (registered trademark), ZIGBEE (registered trademark) capable of communication over a communication distance of several meters to several tens of meters. And so on. In general, no communication fee is required when using these short-range wireless communications. Therefore, if the second communication unit 102 transfers the transfer information using short-range wireless communication, the communication fee can be kept low even if the number of transfer destinations is large.

(Second Embodiment)
The transmission source of the transfer information may transmit the transfer information including identification information that designates the information transfer destination. The information transfer apparatus according to the second embodiment receives transfer information including identification information for specifying a transfer destination of information, and transfers the information to the specified transfer destination. FIG. 3 is a block diagram illustrating a configuration of the information transfer apparatus 200 according to the second embodiment. The configuration of the information transfer apparatus 200 is the same as that of the information transfer apparatus 100 of the first embodiment shown in FIG. 1 except for the first communication unit 101 and the storage unit 103.

  In the present embodiment, the first information 111 includes identification information 118 that designates the transfer information transfer destination in addition to the transfer information 112.

  Therefore, the first communication unit 101 extracts the transfer destination identification information 118 from the first information 111 and outputs it to the storage unit 103. The storage unit 103 stores transfer destination identification information 118. The first communication unit 101 outputs the transfer information 112 as in the first embodiment.

  Then, the second communication unit 102 transmits the transfer information 112 according to the transfer destination identification information 113. The other functions of the second communication unit 102, the function of the transfer control unit 104, and the function of each signal input / output by these units are the same as those of the first embodiment, and the description thereof will be omitted.

As described above, the information transfer apparatus according to the present embodiment receives information including identification information that designates a transfer destination, and transfers the information to the designated transfer destination. Therefore, the transmission source can designate the transfer destination for each transfer information and deliver the information to a desired transfer destination.

(Third embodiment)
When the information transfer is completed, the information transmission source may be notified. The information transfer apparatus according to the third embodiment sends a transfer completion notification to the information transmission source. FIG. 4 is a block diagram illustrating a configuration of the information transfer apparatus 300 according to the third embodiment. The information transfer device 300 is obtained by adding a completion notification request 119 from the transfer control unit 104 to the first communication unit 101 to the information transfer device of the first embodiment shown in FIG. Since the functions of the first communication unit 101 and the storage unit 103 and the functions of the signals input and output by these units are the same as those of the first embodiment, the description thereof is omitted.

  The second communication unit 102 uses the transfer completion notification 116 to notify the transfer control unit 104 that information transfer to all transfer destinations has been completed. The completion of the transfer of information to all transfer destinations is determined based on the reception completion notification 115 from the transfer destination and the identification information of all transfer destinations stored in the storage unit 103.

  When the transfer control unit 104 receives a transfer completion notification 116 indicating that the transfer of information to all transfer destinations has been completed from the second communication unit 102, it outputs a completion notification request 119 to the first communication unit 101. To do. The first communication unit 101 transmits a transfer completion notification 120 to the information transmission source.

  As described above, the information transfer apparatus according to the present embodiment notifies the transmission source that the transfer to all transfer destinations has been completed. Therefore, the transmission source can confirm that the information has been transmitted to all the transfer destinations.

Furthermore, the transmission source notified that the transfer to all transfer destinations has been completed can also confirm that all the transfer destinations exist within the communicable range of the second communication unit 102. When the communicable distance of the second communication unit 102 is short, such as when the second communication unit 102 uses a short-range wireless communication method, the transmission source is a communication device that is a transfer destination in the vicinity of the information transfer device 300. Can also be confirmed.

(Fourth embodiment)
Various information may be included in the transfer completion notification for notifying that the transfer of information has been completed. The information transfer apparatus according to the fourth embodiment adds the position information of the information transfer apparatus to the transfer completion notification. FIG. 5 is a block diagram illustrating a configuration of the information transfer apparatus 400 according to the fourth embodiment. The information transfer apparatus 400 is obtained by adding a position measurement unit 105 to the information transfer apparatus of the third embodiment shown in FIG. The functions of the first communication unit 101, the second communication unit 102, the storage unit 103, and the transfer control unit 104, and the functions of the signals that are input and output by these units are the same as those in the third embodiment. Omitted.

The position measurement unit 105 measures the current position of the information transfer apparatus 400 and outputs position information 121. The method for measuring the current position is not particularly limited. For example, GPS (Global Positioning System) or the like can be used as a position measurement method. When the transfer control unit 104 of the information transfer apparatus of this embodiment receives the transfer completion notification 116 from the second communication unit 102, the position information 121, and a completion notification request 119 is output to the first communication unit 101. The first communication unit 101 transmits a transfer completion notification 120 to the information transmission source.

  As described above, the information transfer apparatus according to the present embodiment notifies the transmission source of the transfer completion notification by including the position information. Therefore, the transmission source can simultaneously grasp the current position of the information transfer device in addition to the information being transmitted to all the transfer destinations.

Then, when the communicable distance of the second communication unit 102 is short, such as when the second communication unit 102 uses a short-range wireless communication method, the transmission source is a communication device in the vicinity of the information transfer device 400. It can be seen that Therefore, the transmission source can also check the approximate current position of the transfer destination communication device.

(Fifth embodiment)
As a fifth embodiment of the present invention, an example of an information transfer system including an information transmission device that is a transmission information transmission source and an information transfer device will be described. FIG. 6 is a block diagram illustrating a configuration of an information transfer system according to the fifth embodiment including an information transmission device 500 that is a transmission information transmission source and two information transfer devices 100-0 and 100-1.

  The information transfer apparatuses 100-0 and 100-1 have the same configuration and function as the information transfer apparatus of the first embodiment.

  It is assumed that the information transmission apparatus 500 has transfer information that has both the information transfer apparatuses 100-0 and 100-1 as transfer destinations. Further, both the information transfer apparatuses 100-0 and 100-1 store the identification information of the information transfer apparatus 100-0 and the information transfer apparatus 100-1 as transfer destination identification information in their respective storage units (see FIG. 1). (Not shown).

  At this time, the information transmission apparatus 500 transmits the first information 111 by designating any one of the information transfer apparatuses 100-0 and 100-1. In the present embodiment, the information transmitting apparatus 500 transmits the first information 111 by designating the information transfer apparatus 100-0.

  The information transfer apparatus 100-0 receives the first information 111. At this time, the information transfer apparatus 100-0 stores the transfer information included in the first information 111 because the identification information is included as a transfer destination. Furthermore, since the information transfer device 100-0 includes the identification information of the information transfer device 100-1 as a transfer destination, the second information 114-1 is included in the transfer information and transferred to the information transfer device 100-1. Forward.

  The information transfer apparatus 100-1 receives the second information 114-1, and stores the transfer information included in the second information 114-1, since its own identification information is included as a transfer destination. Although the identification information of the information transfer device 100-0 is also included as a transfer destination, since the transmission source of the second information 114-1 is the information transfer device 100-0, no transfer is performed.

  In the above embodiment, there are two information transfer apparatuses, but the same applies to the case where the number of information transfer apparatuses is two or more as shown in FIG.

  In addition, the information transfer apparatuses 100-0, 100-1, 100-2, and 100-3 handle the first information including the identification information of the transfer destination like the information transfer apparatus 200 of the second embodiment. It is the same even if it can.

As described above, the information transmission apparatus transfers information to a necessary transfer destination only by transmitting information by designating any one of the plurality of information transfer apparatuses. Therefore, there is an effect that information can be developed very easily from the information transmitting apparatus to a plurality of information transferring apparatuses.
(Sixth embodiment)
When there are three or more information transfer apparatuses, the second information function can be added to another information transfer apparatus by using the information transfer apparatus that has completed the transfer of the second information. FIG. 8 shows the configuration of the information transfer system according to the sixth embodiment of the present invention.

  The information transfer system of this embodiment includes an information transmission device 500 and four information transfer devices 100-0, 100-1, 100-2, and 100-3.

  First, the information transmission device 500 transmits the first information 111 including the transfer information to the information transfer device 100-0. The information transfer device 100-0 transfers the second information 114-1 and 114-2 including the transfer information to the information transfer devices 100-1 and 100-2, respectively. At this time, the information transfer apparatus 100-0 receives the reception completion notification from the information transfer apparatus 100-2, but does not receive the reception completion notification from the information transfer apparatus 100-1. For example, there is a problem in the communication state between the information transfer apparatus 100-0 and the information transfer apparatus 100-1, and the information transfer apparatus 100-1 may not receive the second information 114-1.

  In the present embodiment, when the reception completion notification is not received from the information transfer apparatus 100-1, the information transfer apparatus 100-0 transfers the second information 114-1 to the information transfer apparatus 100-2 without attempting to retransmit the second information 114-1. Request re-transmission of information. That is, the information transfer apparatus 100-0 transmits a retransfer request 122 to the information transfer apparatus 100-2.

  The information transfer apparatus 100-2 that has received the retransfer request 122 retransfers the second information 123 including the transfer information included in the second information 114-2 to the information transfer apparatus 100-1.

  In the present embodiment, since the information transfer apparatus 100-1 does not transfer information, it may be a normal information receiving apparatus that does not have an information transfer function.

As described above, in the information transfer system of this embodiment, information is retransferred using the information transfer apparatus that has received the transfer information. Therefore, even when there is a non-delivery transfer destination that cannot be transferred from the information transfer device that first received the transfer information, the information can be transferred to the non-delivery transfer destination using the information transfer device of the transfer destination. There is an effect.

(Seventh embodiment)
Next, as an embodiment assuming a specific system, an example of an information transfer system using a mobile phone will be described. In the information transfer system according to the seventh embodiment, a communication unit that performs communication using a mobile phone line as a first communication unit, and Bluetooth (hereinafter referred to as “BT” "). FIG. 9 is a block diagram showing a configuration of a mobile phone 600 provided in the information transfer system of the seventh embodiment. The mobile phone 600 operates as an information transfer device or a communication device that transmits information.

  A mobile phone 600 according to this embodiment includes an operation unit 601, a display unit 602, a storage unit 603, a timer unit 604, a communication control unit 605, a BT control unit 606, a GPS control unit 607, and a CPU 608.

  The operation unit 601 is an input device such as a numeric keypad for the user of the mobile phone 600 to operate when transmitting information or using other functions. A display unit 602 displays a telephone number and the like. The storage unit 603 stores information input from the operation unit 601 and data necessary for CPU processing performed to realize various functions. The timer unit 604 measures the time required for CPU processing performed to realize various functions, and outputs time information to the CPU as necessary.

  A communication control unit 605 controls transmission and reception of information using a mobile phone network.

  The BT control unit 606 communicates with a mobile phone having a peripheral Bluetooth communication function using the Bluetooth method.

  The GPS control unit 607 receives a radio wave from a GPS satellite and calculates position information indicating the current position of the mobile phone 600 by a predetermined calculation. In response to a request from the CPU, the calculated position information is output to the CPU.

  The CPU 608 controls each of the above blocks and performs overall control of the mobile phone 600. Specifically, the CPU 608 monitors the communication control unit 605 for incoming calls from the mobile phone telephone network. When an incoming call is detected, the type of incoming communication is identified. The types of communication include voice, data communication, short message service (SMS), and the like. If it is an incoming data communication, the CPU 608 determines whether or not the data transmitted by the broadcast transmission (hereinafter referred to as “broadcast data”) is received.

  If the incoming data communication is an incoming call by broadcast transmission (hereinafter referred to as “broadcast incoming call”), the CPU 608 stores the received data in the storage unit 603 as broadcast data. Then, the CPU 608 activates the BT control unit 606 and searches for a peripheral terminal capable of receiving a broadcast by BT (hereinafter, “BT incoming terminal”). In other words, a terminal capable of receiving a broadcast is a terminal capable of receiving broadcast data. The BT receiving terminal is a mobile phone or the like having a BT communication function.

  When a BT incoming terminal is found as a result of the search, the CPU 608 forms a BT network with the mobile phone 600 as a master and the found BT incoming terminal as a slave. Then, the CPU 608 transfers the broadcast data stored in the storage unit 603 to the BT incoming terminal.

  Note that the communication data transmission source communication terminal (hereinafter referred to as “broadcast transmission terminal”) receives the destination information (hereinafter referred to as “broadcast transmission terminal”) of the destination terminal to which the broadcast data is distributed before broadcast transmission. Broadcast transmission destination information ") is registered in advance. When the broadcast transmission terminal broadcasts the broadcast data, the broadcast transmission destination information is attached to the mobile phone 600 and attached. Accordingly, the mobile phone 600 can transfer the broadcast data to the BT receiving terminal with reference to the broadcast transmission destination information.

  The CPU 608 repeats the broadcast data transfer process described above until the transfer to all surrounding BT receiving terminals is completed. The CPU 608 stops the operation of the BT control unit 606 after completing the transfer of the broadcast data to all the BT receiving terminals, and ends the processing.

  The control flow of the CPU 608 will be described with reference to the flowchart of FIG.

  First, the CPU 608 determines whether there is an incoming call at the communication control unit 605 and whether there is a broadcast incoming call (step S100). If there is no incoming call, the process is terminated. Further, even when there is an incoming call, if the incoming call is not a broadcast incoming call, the process may be shifted to normal incoming call processing. Since normal incoming call processing is out of the scope of the present embodiment, the processing flow in FIG. 10 ends.

  If a broadcast incoming call is detected in S100, the BT control unit 606 is activated (step S101). Then, with reference to the broadcast transmission destination information transmitted from the broadcast transmission source terminal, a search is started to check whether there is a BT receiving terminal included in the broadcast transmission destination information around (step S102). In the background, data is received in parallel, and the received broadcast data is stored in the storage unit 603. In S102, when no BT incoming terminal is found in the vicinity, the BT control unit 606 is stopped.

  In S102, when a BT incoming terminal is found in the vicinity, the broadcast data stored in the storage unit 603 is transferred to the found BT incoming terminal via the BT control unit 606. Then, the process of finding the BT receiving terminal and transferring the broadcast data to the found BT receiving terminal until reception completion notification is received from all the BT receiving terminals included in the broadcast destination address information. Repeat (step S103). That is, transfer to all broadcast delivery destination BT receiving terminals and retransmission until reception completion notification is received are repeated.

  When no new BT receiving terminal is found, that is, when the broadcast data transfer process to all BT receiving terminals included in the broadcast transmission destination information is completed, or when no BT receiving terminal is found, BT control is performed. The unit 606 is stopped (step S104).

  Next, the CPU 608 acquires location information of the mobile phone 600 (step S105). Then, the CPU 608 notifies the broadcast transmission terminal of the completion of the transmission of the broadcast data or the discovery of no BT incoming terminal and the acquired location information (step S106).

  Note that all the BT receiving terminals that have completed the transfer may acquire the position information, and together with all the position information, the completion of transmission of the broadcast data may be notified to the broadcast transmission terminal.

  FIG. 11 shows an image of the overall configuration of the information transfer system of the present embodiment. The broadcast source terminal 700 and the mobile phone 600 that is an information transfer device communicate with each other via the mobile phone network 900.
