2. Description of the Related Art In recent years, the population of users of the Internet has rapidly increased, and the broadband era, which can be said to be a new stage of Internet usage, is about to enter. In broadband communication, the communication band is remarkably widened, so heavy image data transmission and reception, which was traditionally avoided, becomes active.

[0003]

However, when sending e-mail with heavy image data attached to a plurality of parties, the heavy image data is doubled by the number of the parties to be sent and sent out on the network. become. With this, for example, the capacity of the mail server of the Internet service provider is insufficient. In addition, since a large amount of data that is not necessarily useful to the recipient of the mail is sent out on the network, it may affect the traffic volume of the entire network and cause a bottleneck. Further, in the case of a peer-to-peer communication mode such as a mobile phone, there is a problem that heavy data is sent to the addressee side of the mail even if it is unnecessary, without any choice.

The present invention has been made in view of such a situation, and an object thereof is to provide a transmission management technique for performing smooth communication without flowing useless data on a network.

[0005]

One aspect of the present invention relates to a transmission management system.

A storage unit placed locally on the transmitting side, a conversion unit that converts specific data into simple data including information about the specific data, and a transmission processing unit that transmits at least the simple data before transmitting the specific data And, including.

Here, the specific data refers to image data, moving image data, voice data, attached files, etc., which have a relatively large capacity or communication amount. The sender's local field does not necessarily have to be physically in the same terminal as the terminal that actually sends the message, but may be another device connected to the device by a local network. .

[0007] The simple data has a smaller capacity and a smaller amount of communication than the specific data. The information regarding the specific data may indicate the capacity of the specific data, the communication amount, or the like. Here, the communication amount may be calculated, for example, by the product of the communication band and the communication time. When the specific data is moving image data or audio data, the simple data may include data indicating the time required to reproduce the moving image. Simple data is used when specific data is stored, for example, UR
It may include an address such as L, a reception request signal for specific data, and password-like data that enables access to the specific data.

When the message to be transmitted includes the specific data and other data such as text data, the storage unit may store the entire message. Further, when the message to be transmitted includes other data together with the specific data, the transmission processing unit may transmit only the simple data, but only the specific data portion of the message is replaced with the simple data. , The message after replacement may be transmitted.

The transmission management system instructs the transmission processing unit to transmit the specific data only when the addressee of the message can determine whether or not the recipient of the message can receive the specific data. And an instruction unit. The transmission processing unit may receive the instruction from the instruction unit, read the specific data from the storage unit, and transmit the specific data to the recipient.

The intermediary device may further include a period management unit that refers to the registration unit and determines a period in which the specific data is stored in the storage unit. And the data indicating the period may be transmitted to the sender.

The transmission management system may further include an erasing unit for erasing the specific data from the storage unit after the lapse of the period based on the data indicating the period. The erasing unit may be provided locally at the transmitting side. The transmission management system may further include a notification unit for notifying the destination person of the specific data being deleted from the storage unit.

The simple data may include display data that allows the recipient of the message to recognize that the message contained the specific data, and the transmission processing unit replaces the specific data in the message with the simple data. A message containing simple data may be sent to the recipient. In this case, the recipient who receives the message containing the simple data will be informed that the message originally contained the specific data, so if the recipient wants to acquire the specific data, the recipient does not specify the specific data. You can request to receive data.

The judgment unit may be provided in a local place on the transmitting side. In this case, the determination unit may send the simple data to the recipient and make a determination based on the response. In this way, the transmission processing unit may directly transmit the simple data to the recipient or may transmit the simple data to the intermediary device.

Another aspect of the present invention relates to a transmission management method, which comprises a step of detecting, when transmitting a message via a network, whether or not the message includes specific data, and When the specific data is included, converting the specific data into simple data including information about the specific data and at least storing the specific data in a local place on the transmitting side, and at least the simple data before transmitting the specific data.

1 is a block diagram of a transmission management system according to a first embodiment. Transmission management system 1
0 is a sending terminal 20 on the sender side for sending a message,
It includes a destination terminal 40 on the recipient side of the message, and a mediation server 50 that mediates communication between the transmission terminal 20 and the destination terminal 40. These devices are connected via a network such as the Internet or a mobile phone network. The transmission terminal 20 and the destination terminal 40 are PCs, PDAs, mobile phones, and other arbitrary hardware. The configuration of the transmission management system 10 can be realized in terms of hardware by a CPU, a memory, or other LSI of an arbitrary computer, and in terms of software, it can be realized by a program having a transmission management function loaded in the memory. However, here we are drawing the functional blocks realized by these collaborations. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms by only hardware, only software, or a combination thereof.

The transmission terminal 20 includes a detection unit 22 and a storage unit 2.
4, a conversion unit 26, and a transmission / reception processing unit 28. The transmission / reception processing unit 28 performs various transmission / reception processing. Detection unit 22

6 converts the specific data into simple data, and temporarily stores the message in the storage unit 24. The simple data includes a capacity of specific data, a communication amount, an address where a message is stored, a reception request signal of the message, and the like. The transmission / reception processing unit 28 transmits the simple data to the mediation server 50. On the other hand, when the message does not include the specific data, the transmission / reception processing unit 28 performs a normal transmission process. That is, the transmission / reception processing unit 28 directly transmits the original message to the destination terminal 40.

The intermediary server 50 includes a judgment unit 52 and an instruction unit 5
4 and a registration unit 56. The registration unit 56 receives and registers information regarding whether or not the recipient can receive the specific data in advance. When the determination unit 52 receives the simple data from the transmission terminal 20, the determination unit 52 refers to the simple data and determines whether or not the recipient can receive the specific data. Judgment part 5
2 may be determined by referring to the registration unit 56, or may be determined by checking the reception state of the destination terminal 40 when receiving the simple data.

When the recipient can receive the specific data, the instruction unit 54 instructs the transmission / reception processing unit 28 to transmit the message including the specific data. In this case, the transmission / reception processing unit 28
Sends a message to the recipient.

The intermediary server 50 monitors the reception state of the destination terminal 40 and, when the destination terminal 40 becomes able to receive the specific data, instructs the transmission / reception processing section 28 to transmit a message including the specific data. In response to this, the transmission / reception processing unit 28 transmits a message including the specific data to the recipient. As described above, in the present embodiment, the simple data is used only by the mediation server 50 to determine the reception state of the addressee.

FIG. 2 shows the internal structure of the registration unit 56. The registration unit 56 has a “destination terminal” column 70, a “continuously receivable communication amount” column 72, and a “message unacceptable time with a large communication amount” column 74. For example, when the destination terminal is “A”, the communication amount of data that can be received at any time is “1 MB”. The time during which data with a communication volume larger than 1 MB cannot be received is "14:00 to 18:00 on September 10". Based on the simple data transmitted from the sender, for example, if the communication volume of the specific data is 1 MB or less, the determination unit 52 instructs the transmission processing unit 28 to transmit a message including the specific data to the recipient. do. In addition, when the communication amount of the specific data is larger than 1 MB and the time when the simple data is transmitted from the sender is the unreceivable time, the determination unit 52 notifies the transmission processing unit 28 of the untransmittable data. Here, in the “destination terminal” column 70, the destination terminal “A”,
Although shown as “B”, “C”, etc., these are only schematic representations of the address and identification number of the terminal. Although not shown here, the registration unit 56
May register the type of receivable data, the always receivable communication speed, and the like.

FIG. 3 is a flow chart showing the processing procedure of the transmission management system shown in FIG. When there is a message transmission command in the transmission terminal 20 (S100), the detection unit 22 determines whether or not the message includes specific data (S102). When the message does not include the specific data (No in S102), the transmission / reception processing unit 28 performs a normal transmission process (S104). When the message includes the specific data (Yes in S102), the conversion unit 26 stores the message in the storage unit 24 (S106) and converts the specific data into simple data (S).
108). The transmission / reception processing unit 28 transmits the simple data to the mediation server 50 (S110).

When the mediation server 50 receives the simple data, the judging section 52 judges whether or not the recipient of the message can receive the specific data (S112). When the specific data can be received (Yes in S112), the instruction unit 54 instructs the transmission / reception processing unit 28 to transmit the specific data (S114). When the specific data cannot be received (No in S112), the mediation server 50 monitors whether or not the recipient can receive the specific data, and when the specific data can be received, the mediating server 50 sends the specific data to the transmission terminal 20. Instruct to send.

When the transmission terminal 20 receives the specific data transmission instruction, the transmission / reception processing unit 28 reads the message from the storage unit 24 (S116) and transmits the message to the destination terminal 40 (S118).

In the present embodiment, when the specific data having a large communication volume is transmitted, the specific data is transmitted after confirming the receiving state of the addressee. It is possible to avoid the situation where the data cannot be received.

FIG. 4 is a block diagram of a transmission management system according to the second embodiment of the present invention. Hereinafter, the same configurations as those in FIG. The new configuration in FIG. 4 is that the mediation server 50 further includes a reception unit 58. The reception unit 58 receives a reception request for specific data from the recipient.

In the present embodiment, the simple data includes display data that allows the recipient of the message to recognize that the message contained specific data. When the determination unit 52 determines that the destination terminal 40 cannot receive the specific data, the intermediation server 50 transmits the simple data to the destination terminal 40. When the recipient receives the simple data and displays the simple data, the presence of the specific data can be known from the display data. When the recipient clicks the display portion of the display data, the reception request signal is transmitted to the mediation server 50. When the reception unit 58 receives the reception request signal, the instruction unit 54 instructs the transmission / reception processing unit 28 of the transmission terminal 50 to transmit the specific data. In response to this, the transmission / reception processing unit 28 transmits the specific data to the destination terminal 40. As described above, in the present embodiment, the simple data is used by the mediation server 50 to determine the reception state of the addressee and to request reception of specific data from the addressee.

FIG. 5 is a flow chart showing the processing procedure of the transmission management system shown in FIG. Hereinafter, the same processes as those in FIG. 3 will be assigned the same reference numerals and the description thereof will be appropriately omitted. In the new processing in FIG. 5, after the determination unit 52 determines whether or not the specific data can be received (S112), if the specific data cannot be received (No in S112), the mediation server 50.
Transmits simple data to the destination terminal 40 (S130)
In point. When the destination becomes able to receive the specific data, the destination terminal 40 requests the relay server 50 to receive the specific data (S132). When the reception unit 58 receives the reception request from the destination terminal 40, the instruction unit 54 instructs the transmission terminal 20 to transmit the specific data (S134).

When the transmitting terminal 20 receives an instruction to transmit specific data from the intermediary server 50 (S114 or S
134), the transmission / reception processing unit 28 reads the message from the storage unit 24 (S136).

According to this processing, since the specific data is transmitted to the destination only when the destination desires, useless data can be prevented from being sent out on the network.
In addition, it is possible to prevent undesired transmission of a large amount of communication data that the recipient does not want to acquire.

FIG. 6 is a flow chart showing another example of the processing procedure of the transmission management system shown in FIG. 1 or 4. Hereinafter, the same processes as those in FIGS. 3 and 5 are designated by the same reference numerals, and the description thereof will be appropriately omitted. In the new process in FIG. 6, when the destination person can receive the specific data after the simple data is transmitted to the destination terminal 40 by the mediation server 50 (S130), the destination terminal 40 receives the specific data in the transmitting terminal 20. The point is that the request is made directly (S140). According to this processing, even if the mediation server 50 does not have the reception unit 58, the specific data can be transmitted to the recipient only when the recipient desires.

FIG. 7 is a block diagram of a transmission management system according to the third embodiment of the present invention. Hereinafter, the same configurations as those in FIG. In the new configuration in FIG. 7, the intermediary server 50 has a period management unit 60.

To decide. The period management unit 60 adds data indicating the determined period to the simple data and transmits it to the recipient. At the same time, the period management unit 60 also transmits the data indicating the period to the transmitting terminal 20. Although not shown, the storage unit 24
May have an erasing unit that erases specific data from the storage unit 24, and the erasing unit may store the storage unit 2 based on the data indicating the period.
Delete specific data from 4. As a result, the recipient can know the time when the specific data is stored, that is, the period during which the request for receiving the specific data can be made. On the other hand, the sender can delete the specific data without leaving it in the storage unit 24 forever, and can delete the unnecessary data.

FIG. 8 is a block diagram of a transmission management system according to the fourth embodiment of the present invention. Hereinafter, the same configurations as those in FIG. In the present embodiment, the transmission management system 110 differs from the first to third embodiments in that it does not have a mediation server.

When the message to be transmitted contains the specific data, the transmission / reception processing unit 28 transmits the message in which the specific data is replaced with the simple data to the addressee. The transmission / reception processing unit 28 transmits the specific data when a reception request is received from the recipient.

FIG. 9 is a flow chart showing the processing procedure of the transmission management system shown in FIG. Hereinafter, the same processes as those in FIG. 3 will be assigned the same reference numerals and the description thereof will be appropriately omitted. In the new processing in FIG. 9, after the conversion unit 26 converts the specific data into the simple data (S108), the specific data in the message is replaced with the simple data (S150), and the replaced message is sent to the destination terminal 40. It is at the point of transmitting (S152). If the message includes only specific data, step 150 may be omitted and only simple data may be transmitted to the destination terminal 40 in step 152.

According to the present embodiment, even if the sender intends to send a message including the specific data to the recipient, the specific data is actually stored in the storage unit 24 on the sender side and simplified. Only messages that contain data are sent to the recipient. The recipient can know that the original message contained the specific data, and if he / she wants to acquire the specific data, it sends a specific data reception request to the sender to transmit the specific data from the transmission terminal 20. Can be asked. Therefore, it is possible to prevent the data having a large amount of communication that the recipient does not want to receive from being automatically sent.

The present invention has been described above based on the embodiments. It is understood by those skilled in the art that the embodiments are exemplifications, that various modifications can be made to combinations of respective constituent elements and respective processing processes, and that such modifications are within the scope of the present invention. . Hereinafter, such a modified example will be described.

In the embodiment, the judgment unit 52 in the intermediary terminal 50 judges the reception state of the addressee by referring to the registration unit 56, but the judgment unit 52 cooperates with the program having the schedule function to make the destination. The recipient's reception status may be determined by grasping the schedule of the recipient.

In the embodiment, the transmission / reception processing unit 28 of the transmission terminal 20 transmits the specific data to the addressee when there is a request for receiving the specific data from the intermediary server 50 or the destination terminal 40. Even if the system is used, the communication cost for transmitting the specific data is imposed on the sender side. However, the intermediary server 50 may manage the transfer of data between the transmission terminal 20 and the destination terminal 40, and the communication cost for actively transmitting the specific data may be charged to the sender side.

The processing of the intermediary server 50 described in the embodiment may be performed by the Internet service provider at the same time as the conventional connection service, but a separate service entity that manages communication between the sender and the recipient. You can go.

The technique of the present invention is particularly useful for sending a message including specific data to an unspecified number of recipients. In this case, if the specific data is stored in the sender's public cache server and the server is always connected, the recipient who receives the message can send the reception request signal included in the simple data. Can receive the specific data.

In this case, for example, if the specific data has high confidentiality for business use, it is necessary to set permission to access the specific data, and to access the simple data to the specific data. By incorporating a password-like signal for authenticating, it is possible for only the recipient who receives the simple data to access the specific data.

When the mailer on the addressee side receives the specific data after receiving the message including the simple data, the specific data is replaced again with the simple data, and the original message can be seen on the addressee side. You may do it.

Further, in a videophone using the Internet or wireless, when the videophone is called and the other party is not connected due to communication or the like, the video data is stored in his / her local terminal and is used as simple data. The technique of the present invention can also be used as an answering machine for a videophone by transmitting only the presence of video data to the recipient.

As described above, according to the present invention, it is possible to prevent the processing of flowing data having a large communication amount, which is not always useful, on the network.
