Description

Description: TECHNICAL FIELD The present invention relates to a center-end type communication system in which an information center and a plurality of terminal devices are connected via a communication network. When code data such as fax data is broadcasted to multiple terminal devices via a communication network,
The present invention relates to a delivery result notifying method in which a communication network notifies an information center of whether or not code data has been normally delivered to each terminal device.

(Conventional technology) Conventionally, in the case of center-end type communication,
When the code data is transmitted from the information center to a large number of called devices in one communication, the communication network individually notifies the information center of the result of transmission to each called device. as a result,
Since the delivery result is notified to the information center in a concentrated manner, the information center cannot transmit the next code data or the like for a certain period of time. Further, in the communication network, the next communication result cannot be notified until the communication line with the information center becomes idle, so that it is necessary to store the result in the communication network for a long time. Furthermore, when the information center provides a service by borrowing a computer for a certain period of time, there is a restriction that when the service time ends, the communication network cannot notify the transmission result.

FIG. 5 shows a schematic configuration of a center-end type communication system. In FIG. 5, a computer 1 corresponding to an information center
The plurality of terminal devices 3 are connected by a line 4 via a communication network 2. FIG. 6 shows an example of a communication sequence of this type of center-end type communication system. Hereinafter, a conventional delivery result notifying method will be described.

When a call is made from the computer 1 (information center) to the terminal device 3, a call request is made to the communication network 2 by a signal A. A response is returned from the communication network 2 by a signal B. The computer 1 transmits code data to the communication network 2 by a signal C, and a response is returned from the communication network 2 by a signal D. The computer 1 transmits a termination request to the communication network 2 by a signal E, and a response is returned from the communication network 2 by a signal F.
Thus, a series of data transfer sequence is completed.

On the other hand, the communication network 2 transmits the received code data to the terminal device 3 on the receiving side designated by the computer 1 on the transmitting side by a signal C. The terminal device 3 responds to the communication network 2 with a signal I indicating that the code data has been received normally or abnormally. Each time the communication network 2 receives the signal I returned from each terminal device 3 on the receiving side, the communication network 2 individually returns a transmission result (normal or abnormal) of the code data to the computer 1 by the signal G,
The computer 1 responds to the communication network 2 with a signal H.

This is the same in the case of so-called broadcast communication in which the information center (computer 1) transmits coded data to a plurality of receiving side signals (terminal devices 3) in one communication.
Has notified the information center of the result of transmission to each receiving side device individually by the signal G.

Regarding this, the center in the facsimile communication network
A conventional sequence example of end-type facsimile broadcasting will be described with reference to FIG.

Signal CMS from computer 1, which is the information center on the transmitting side
When a broadcast request is made to the facsimile communication network 5 by (broadcast communication request), the facsimile communication network responds with a signal + RSP, and then returns a communicable response with the signal MCA. Facsimile communication network 5 from computer 1
The sequence of a page transmission request by the signal PGT and the sequence of image information transmission by the signal PIX are sequentially advanced, and the communication end is signaled by the signal CED to the facsimile communication network 5.
And ends the communication.

On the other hand, in the facsimile communication network 5, if the image information (PIX) is not normally delivered to the facsimile terminal device 3 on the receiving side, a non-delivery notification is sent by the signal SIM for each of the terminal devices 3 to the computer 1 on the transmitting side. Send notification to Also,
When the request of the delivery result is previously requested from the computer 1 on the transmitting side, the delivery result is notified by the DIM signal for each facsimile terminal device 3 similarly to the signal SIM.

(Problems to be Solved by the Invention) As described above, in the conventional center-end type communication system, the delivery result is individually notified for each receiving side device from the communication network to the information center. There is a problem as follows.

(A) In the case of broadcast communication, the delivery result of each terminal device is sent to the information center at the same time.
The next transmission cannot be made.

(B) If the information center computer interrupts the service before receiving all the delivery results, the delivery result cannot be notified.

(C) Since there is a high possibility that the transmission request and the delivery result notification will collide between the information center and the communication network, the communication efficiency is low.

(D) When the phenomenon (c) occurs, the unit price of transmitting one data increases in order to redo the communication.

(Object of the Invention) An object of the present invention is to provide a center-end type communication system in which an information center and a plurality of terminal devices are connected via a communication network, when a broadcast is requested from the information center to the communication network. It is an object of the present invention to improve the congestion of the communication line between the communication network and the information center and the inefficiency of communication, which the conventional delivery result notification method has.

(Structure of the Invention) In order to achieve the above object, the present invention provides a broadcast request signal transmitted by a transmission side device, which is provided with a field indicating a destination (delivery result notification destination) for notifying a delivery result,
At the time of broadcasting, the communication center transmits a broadcast request signal to the communication network by designating a delivery result notification destination in the field, and receives the broadcast request signal from the information center, A delivery result notification destination of the field in the broadcast request signal is stored, a broadcast is delivered to a plurality of terminal devices in accordance with the broadcast request signal, and a delivery result to all the terminal devices is received. The editing is performed, and the edited result is collectively notified to the stored delivery result notification destination.

(Effects of the Invention) As described above, according to the present invention, a center / information center and a plurality of terminal devices are connected via a communication network.
In an end-type communication system, at the time of broadcasting, a destination for notifying a delivery result is designated in a predetermined field in a broadcast request signal transmitted by the information center. In the communication network, the delivery designated by the information center is designated. By storing the destination for notifying the result and performing the broadcast according to the broadcast request signal, all the delivery results (delivery, non-delivery) are edited and notified to the designated destination in a lump. Even when broadcasting from an information center to a large number of terminal devices, congestion of the communication line between the communication network and the information center can be avoided, and the information center can improve communication efficiency by waiting for receiving a delivery result notification. Processing can be performed without considering the decline of the delivery, and the delivery result can be reliably sent to any specified destination.
Moreover, the notification can be made in a form that is easy to process.
