When the first specific information and the second specific information are received, the communication information is received by requesting the transmitting device to transmit the communication information, and based on the first communication information, the communication information is transmitted to the plurality of receiving devices. and a relay device that performs transmission.

(Industrial Application Field) The present invention relates to a remote polling relay broadcast system, and relates to a remote polling relay broadcast system that can be applied, for example, to communication of image information using a facsimile machine.

[Conventional technology]

Known facsimile machines are capable of transmitting image information of a document, such as text and photographs, to a long distance using a communication line. At present, such facsimile devices are generally widely used as office automation is becoming more widespread, since image communication can be carried out via public telephone lines.

In this popular facsimile machine, as the amount of information to be transmitted increases, there is an increasing demand for efficiency in communication costs and the like.

The functions realized in response to the request are a relay request and a relay redirection request.

FIG. 5 shows a conventional communication method using a relay request or a relay report request. Hereinafter, place names in parentheses such as "Kawasaki" indicate the station equipment at that location.

In the figure, the source is "Kawasaki" 510, and first,
Normally, when sending to "Department IJ413.'Department 2" 415 and rDepartment 3J417 within the department, they are sent individually as shown by the dotted line, but this increases the communication cost and communication time, so it is necessary to send multiple messages at once. “Tokyo” 2, which is close to the destination of
Send to 10. At this time, a request is made to "Tokyo" 210 to send a broadcast, and "Tokyo" 210 is sent to a plurality of destinations. Also, for example, “Osaka” 220, which is a remote location,
If you send a message to ``Yokohama'' 411, please pay the communication fee to iE.
A relay request is sent to ``Yokohama'' 411 for the purpose of ``1''. Additionally, different networks (e.g. external and internal lines, G31M
and G4y4 etc.) "Sendai 1" 433 and "Sendai 2"
When sending to J435, it is impossible to send directly as shown by the dotted line, but first, send a circular to "Sendai" 430, which has access to both networks, and send it to "Sendai" 43.
Send via 0.

The above is the conventional method using relay requests and relay broadcast requests, but since there are still few facsimile machines that have the request function, such devices cannot send the same message to multiple remote parties one by one, unlike in the past. In some cases, information had to be sent, and communication between different types of networks was impossible.

Therefore, as a function to compensate for this situation, a method using polling relay broadcasting has been proposed.

FIG. 6 shows a method using polling relay broadcasting.

In the figure, the relay station 610 polls the "Kawasaki" 4510, receives the data in the "Kawasaki" SLO and information (telephone number) indicating the destination, and
Store in 1. Relay station 610, which has received the data and information indicating its destination, transmits the data to slave stations 631, . . . based on the information indicating the destination. 631□,...,631. ,
Send to.

[Problem to be solved by the invention]

However, this polling relay relay communication also has the following problems.

That is, polling relay broadcasting requires operation by an operator at a relay station, and especially when communicating between different types of networks, communication cannot be performed unless operations are performed at a station connected to both lines. Furthermore, if only the relay station is located far away from other stations, there is a problem in that communication charges become extremely high.

The present invention was created in view of these points, and an object of the present invention is to provide a remote polling relay broadcasting system that allows efficient and economical communication.

[Means to solve the problem]

FIG. 1 is a block diagram of the principle of the remote polling relay relay system according to the present invention.

In the figure, transmitting means 111 transmits communication information.

Each of the plurality of receiving means 113 receives communication information.

The communication activation means 115 transmits first specifying information that specifies the transmitting section 111 as a transmission source and second specifying information that specifies a destination.

When the communication activation means 115 receives the first specific information and the second specific information, the relay means 117 receives the communication information by requesting the transmission means 111 to transmit, and transmits the communication information to the second specific information. Based on the plurality of receiving means 113
Sends communication information to.

Therefore, as a whole, the communication activation means 115 transmits the first specifying information for specifying the source and the second specifying information for specifying the destination to the relay means 117, and the relay means 117 performs the polling relay circular communication based on the information. is configured to do so.

[For production]

The communication activation means 115 transmits to the relay means 117 first specifying information specifying the transmitting means 111 as the sender and second specifying information specifying the destination.

Relay means 117 requests transmission means 111 to transmit, and upon receiving the transmission request, transmission means 111 transmits communication information to relay means 117. Transmission means 11
The relay means 117, which has received the communication information from the relay means 1, transmits the communication information to the plurality of reception means 113 based on the second specific information.

In the present invention, the relay means 117 requests the transmission means 111 to transmit based on the first specific information and the second specific information from the communication activation means 115, and sends a plurality of reception requests based on the second specific information. Since the communication information is transmitted to the means 113, efficient and economical communication can be performed.
