Abstract

PURPOSE:To attain smooth data exchange requiring immediacy by operating a message collection program and a message distribution program on a value added network VAN center with priority as required. CONSTITUTION:A data sent from a terminal equipment 1 is received in a VAN center 4 by using a message collection program 5, a user data is checked and when the processing type requires the immediate processing, the message collection program 5 and the message distribution program 8 are synchronized via a program buffer 6 to apply immediate data reception and transmission. Then in the message distribution program 8 the terminal equipment 2 being the final destination is called based on the user data to distribute the data, When the processing type in the message collection program 5 is the storage processing, the message collection program 5 stores a data in a message distribution and collection disk device 7 and the stored data is distributed by the message distribution program 8 in response to the request from the terminal equipment 3.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applied to a value-added network (hereinafter referred to as VAN). In particular, it relates to means for processing data exchanges in real time.

〔overview〕

In a data exchange device in a VAN data exchange system, the present invention enables smooth data exchange that requires immediacy by operating the collection program and distribution program on the VAN center with priority as necessary. This is how it was done.

[Conventional technology]

A conventional data exchange system is a storage type data exchange system that stores data on a VAN center, and a collection program and a distribution program operate asynchronously.

[Problem that the invention seeks to solve]

Data communications in companies include some that require immediate processing and others that can be stored and processed, depending on the business. By the way, conventional storage-type data exchange systems are not suitable for data that requires immediacy because they are stored in a disk device on the VAN center, and if immediacy is required, public lines must be used separately. There are drawbacks. Furthermore, when using public lines, communication speeds and transmission procedures must be unified between the sending and receiving sides.

SUMMARY OF THE INVENTION The present invention aims to eliminate such drawbacks and to provide a data exchange device capable of exchanging data that requires immediacy.

[Means for solving problems]

The present invention provides a first means that is included in a central office that accommodates a plurality of terminals constituting a value-added network, and stores a collection program for receiving data arriving from the terminals at a predetermined operation timing. A data exchange device comprising a storage means for temporarily accumulating data received by the first means and a second means for storing a distribution program for transmitting the data received by the first means to a specified destination at a predetermined operation timing. A recognition means that recognizes the content of the check code included in the data to be sent, synchronizes the operation timing of the collection program with the operation timing of the distribution program, and immediately transfers the stored contents of the first means to the second means. program buffer means for giving;
When giving the data received by the first means to the second means, a determination is made to instruct either to pass the data through the storage means or through the program buffer means depending on the recognition result of the recognition means. It is characterized by comprising an instruction means.

[Effect]

Determines the data processing type and synchronizes the collection and distribution programs for data that requires immediate processing.
Instant data exchange via program buffer.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figure is a block configuration diagram showing the configuration of this embodiment. As shown in the figure, the VAN center 4 has a collection program 5,
A distribution program 8, a program buffer 6 that performs inter-program communication, and a collection and distribution disk device 7 that performs storage processing.
and each terminal 1.2 and 3 is connected to a VAN center 4. That is, this embodiment is included in a VAN center 4 that is a central office that accommodates a plurality of terminals 1.2.3 that constitute a value-added network, and processes data arriving from these terminals 1.2.3 by predetermined operations. A first means for storing the collection program 5 received at a timing, a collection and distribution disk device 7 which is a storage means for temporarily storing the data received by this first means, and a predetermined destination for the data received by this first means. Distribution program 8 to be sent at the operation timing of
Further, as a feature of the present invention, a recognition means (not shown) that recognizes the content of the check code included in the data arriving from the terminal L2.3, and a collection program 5. and a program buffer 6 that synchronizes the operation timing of the distribution program 8 with the operation timing of the distribution program 8 and immediately provides the stored contents of the first means to the second means, and the data received by the first means to the second means. Depending on the recognition result of the recognition means, the data is sent via the storage means or to the program buffer 6.
and judgment instruction means (not shown) for instructing either to go through the.

Next, the operation of this embodiment will be explained.

When transmitting data, the terminal 1 inserts the processing type (immediate or stored) into the user data as a check code, and transmits the data to the VAN center 4. VA
At the N center 4, the transmitted data is received by the collection program 5, and the user data is checked. When the processing type is immediate processing, the collection program 5 and distribution program 8 are synchronized with each other via the program buffer 6, and data is received and transferred immediately. Next, the distribution program 8 calls the final destination terminal 2 based on the user data and distributes the data (data flow shown by dotted line A). Further, if the processing type in the collection program 5 is storage processing, the collection program 5 stores data in the collection and distribution disk device 7, and this stored data is transmitted to the distribution program 8 in response to a request from the terminal 3. distributed (data flow shown by the dotted line).

〔Effect of the invention〕

As explained above, in the present invention, the VAN center determines the type of data processing (immediate or stored) and performs processing according to this determination, so companies can use communication means (VAN or This has the effect of eliminating the need to separate public lines.

Furthermore, since the collection program and the distribution program are synchronized but independent, data can be exchanged even between models using different protocols.
