(Prior Art) Conventionally, multiple terminal devices have been connected to a central processing unit.
Online message exchange systems for mutually sending and receiving messages are widely used.

By the way, in this system, when a message to be sent to a terminal device that is not operating at night occurs, the message is stored in the central processing unit and sent when the terminal device starts operating. Processing such as discarding the message was performed within the central processing unit.

However, according to the method of transmitting stored messages when the terminal device starts operating, messages that have become unnecessary due to the passage of time are also sent primarily, and extra time is required to send the truly necessary messages. This problem arises.

Furthermore, the method of discarding messages within the central processing unit has the problem that the messages cannot be retrieved even if they are needed later.

(Problems to be Solved by the Invention) The present invention was made in view of the above-mentioned circumstances; it does not take extra time to send out really necessary messages, and the necessary messages can be freely sent later. The purpose of the present invention is to provide an online message exchange system equipped with a message transmission management function that can be used.

[Configuration of the Invention] (Means for Solving the Problems) The online message exchange system of the present invention transmits messages from a central processing unit to a terminal device during a period when one of the terminal devices is not in operation. , the management items are made to correspond to the messages generated during the period, the management items and the messages generated are stored in respective predetermined files, and when the terminal device starts operating, Message transmission management means for transmitting the management item and for extracting a message corresponding to the management item from the predetermined file and transmitting it to the terminal device when a management item is instructed from any terminal device. There is.

(Function) In the online message exchange system of the present invention, when a message to be sent to any terminal device occurs during a period when that terminal device is not in operation, the message transmission management means sends the generated message to the terminal device. This management item and the generated message are respectively stored in predetermined files, and the management item is transmitted when the terminal device starts operating. When a management item is instructed from any terminal device, the message corresponding to the management item is extracted from the predetermined file and sent to that terminal device.
When the terminal device side starts operating, the amount of information sent from the central processing unit side is reduced, and the terminal device side can later freely retrieve generated messages stored in the predetermined file according to instructions from the management items. be able to.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the overall configuration of an embodiment of the system of the present invention.

The system of the present invention has a plurality of terminal devices connected to a central processing unit, similar to the conventional online message exchange system.

The central processing unit C of the system of this embodiment includes a transmission processing section 1 that transmits messages to each terminal device, a message management section 2 that performs management control of message transmission to each terminal device as described later, and a message management section 2 that performs management control of message transmission to each terminal device. The message management section 2 is connected to a storage section 4.

FIG. 2 shows the message management section 2 and storage section 4.
FIG. 2 is a diagram showing a specific configuration of the system.

In the figure, reference numeral 5 denotes a management control unit which, when a message to be sent to any terminal device occurs, determines whether or not to execute the transmission based on the operating state of that terminal device;
7 is a management item processing unit that outputs management items to be described later together with a new message to the transmission processing unit 1 when the terminal device starts operating, and 7 is a storage unit that stores messages corresponding to management items instructed from the terminal device through the reception processing unit 3. 4 is a terminal instruction processing unit extracted from 4; 8 is a correspondence information file that stores correspondence information between messages generated within the system during periods when the terminal device is not in operation and management items that identify them; 9 is a correspondence information file that stores messages This is the message file to be stored.

The operation of the system of this embodiment will be explained below according to each country.

First, when a message to be sent to any terminal device occurs, the management control section 5 of the message management section 2 determines the operating state of the corresponding terminal device, and if it is in operation, the message is sent to the transmission processing section 1. (line LO).

If the corresponding terminal device is not operating, the message is sent to the message file 9 (line Ll
), and the management item that specifies it is stored in the correspondence information file 8, and the message is not transmitted.

Then, when the terminal device starts operating, the management item processing unit 6 extracts the management item that specifies the message to be sent to the corresponding terminal device from the correspondence information file 8 (line L3),
The data is sent to the transmission processing unit 1 (line L4).

The instruction from the terminal device is passed from the reception processing section 3 to the terminal instruction processing section 7 (line L5), and the terminal instruction processing section 7 searches for the management item specified by the terminal device in the correspondence information file 8 (line L6), and sends a message. Extract the message corresponding to the management item from file 9 (line L7)
, is sent to the transmission processing unit 1 (line L8).

Thus, in the system of this embodiment, when a message to be sent to one of the terminal devices occurs during a period when the terminal device is not in operation, the message management unit 2
A management item is associated with the generated message, this management item and the generated message are stored in the storage unit 4, and the management item is transmitted when each terminal device starts operating. When a certain management item is specified, a message corresponding to that management item is extracted from the storage unit 4 and is controlled to be sent to the terminal device. In addition to reducing the amount of information to be transmitted, the terminal device side can later freely retrieve messages that have already been generated and stored in the storage section 4 in accordance with instructions from the management items.

[Effects of the Invention] As explained above, in the online message exchange system of the present invention, the message transmission management means corresponds management items to messages generated during a period when one of the terminal devices is not in operation. The management item and the generated message are each stored in a predetermined file, and the management item is transmitted to the terminal device when the terminal device starts operation, while the management item is transmitted from any terminal device. Since the message corresponding to the management item is extracted from the predetermined file and transmitted to the terminal device, the amount of information transmitted from the central processing unit when the terminal device starts operating is reduced. As a result, it does not take extra time to send the really necessary messages.

The terminal device side can later freely retrieve generated messages stored in a predetermined file according to instructions from the management items.

Furthermore, as a secondary effect, paper can be restricted when the terminal device prints out the message.
