Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for transmitting messages, particularly a message transmission system called an advanced information manager, in which one or a series of message data to be sent is previously transmitted to, for example, a center. In a message transmission method that stores messages on the system and sends them to the true destination as needed, the concept of a logical destination is introduced, and message data is transmitted according to the attributes of the logical destination using a so-called drop-off method. The present invention relates to a message transmission system in which it is possible to arbitrarily select between transmission and redundant transmission of message data.

In the message transmission method called Advanced Information Manager (AIM) mentioned above, message data transmission using the so-called drop-off method has conventionally been adopted.
It has not been possible to arbitrarily select between transmission using the above-mentioned dropout method and message data transmission using the so-called redundant transmission method, as required. In addition,
Message data transmission using the above-mentioned de-transmission method is as follows:
In general, when a certain message is sent, it can be considered that the transmission is completed regardless of whether the transmission result is normal or abnormal, and message data sending using the redundant sending method is generally the same as the one described above. It may be considered that the transmission is completed only when the transmission result is normal and the post-processing in the sending device is completed normally.

On the other hand, in the above-mentioned message transmission method called advanced information manager, when message data is stored, a logical or virtual logical destination is simply specified, and the message data is not actually sent. A method of transmitting data by specifying the true destination, that is, a workstation (also called a physical destination) at the point when the data is sent, has been considered (Japanese Patent Application No. 108401-1983).
(Refer to No. - Message Exchange System Control Method).

In the method for providing logical destinations, the present invention divides the logical destination into a logical destination (referred to as a standard type logical destination) that performs sending using the above-mentioned dropout method and a logical destination that performs sending using the redundant sending method (completion type logical destination). The purpose of this invention is to make it possible to arbitrarily select between transmission using the dropout method and transmission using the redundant transmission method. Therefore, the message transmission method of the present invention is
A system and a terminal system are provided, one or a series of message data to which a logical destination is assigned is stored as a transmission queue on a center system, and the logical destination and a work station on the terminal system are A message transmission method for sending said one or a series of message data to said work station based on a logical destination ON command indicating said one or more standard type a logical destination correspondence section, one or more completion type logical destination correspondence sections, a logical destination table corresponding to each logical destination correspondence section, and one or more logical destination correspondence sections stored as a sending queue in each logical destination correspondence section. A serial number management file for a series of message data is created, and the one or series of message data is stored in one of the standard logical destination correspondence sections.
or one of the completion type logical destination corresponding parts by a command, and in sending the message data in response to the logical destination on command; , one or a series of message data connected to the standard type logical destination corresponding section is assigned a serial number and sent out sequentially, and during that time, if there is a sending failure for any one or more message data, Even if the message data that can be sent is sent next, the transmission is completed by sending the next message data that can be sent, and one or a series of message data connected to the completion type logical destination corresponding section is assigned a serial number or Send sequentially without attaching message data, and if a sending failure occurs in any one message data during that time, wait until the sending failure is removed, send messages after that message sequentially, and complete sending. The present invention is characterized in that the manner in which the message is sent can be selected by the operator. This will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram illustrating an embodiment of the present invention, FIG. 2 is an explanatory diagram illustrating processing at a message accumulation stage, and FIG. 3 is an explanatory diagram illustrating an embodiment of processing at a message sending stage according to the present invention. An explanatory diagram for explanation is shown.

In FIG. 1, 1 is the center system, 2-
0, 2-1, . . . are terminal systems, 3-0 to 3-P are standard logical destination corresponding units, and 4-0
to 4-q are completion-type logical destination correspondence units, respectively, and 5 is a logical destination table that stores which logical destination correspondence unit 3-0 to 4-q a given logical destination is associated with. , 3-0A to 3-0D are message data connected to one standard type logical destination correspondence unit 3-0 and stored as a sending queue, and 4-0K.
4-0N are message data, which are connected to one completion type logical destination correspondence unit 4-0 and stored as a sending queue, and 6 is a serial number management file, each of which corresponds to each standard type. Message data 3-0A to 3-0D, etc. connected to logical destination correspondence units 3-0 to 3-p are assigned transmission serial numbers and managed. 7 is a serial number management file, each of which has a serial number management file. 8-0, 8 that assigns a transmission sequence number to the message data 4-0K to 4-0N, etc. connected to each completion type logical destination corresponding unit 4-0 to 4-q, and manages the message data 4-0 to 4-q;
-1, . . . and 9-0, 9-1, . . . represent work stations, respectively.

For example, if the terminal system 2-1 or center system 1 wants to transmit message data A, O, C, etc. to the terminal system 2-0,
For example, from the work station 9-0 or from an input device (not shown) in the center system 1, an instruction is given as to whether the message data is to be sent in the skip mode or the redundant mode, and a logical destination is assigned. Issue. This state is shown in FIG. 2, where the stack processing unit (not shown) in the center system 1 is one of the standard type logical destination corresponding units 3 in the vacant state when using the above-mentioned drop-off method. For example, by selecting 3-0, the corresponding message data is stored in the sending queue as data 3-0A, 3-0B,
3-0C, 3-0D, . . . , and write the logical destination of the data connected to the corresponding section 3-0 on the logical destination table 5. In addition, in the case of the above redundant sending method, one of the completion type logical destination correspondence units 4 in an empty state, for example 4-0, is selected and the message data is sent to the sending queue with data 4-0K,
4-0L, 4-0M, 4-0N, . . . , and write the logical destination of the data connected to the corresponding section 4-0 on the logical destination table 5.

In this state, for example, the terminal system 2-0
When it becomes possible to receive the logical destination on the terminal system 2-0, for example from the work station 8-0 or from the center system 1.
Give a command (LD-ON command). The command includes the logical destination Y of the message to be sent, for example "LD-ON, LD=Y, WS=X".
and the work/work that should actually send the message.
Station 8-0 (physical destination=X) is designated.

This state is shown in Figure 3 as "LD-ON command input"
It is shown as. Based on the above command, the logical destination table 5 is indexed, and it is determined which logical destination corresponding part the message to which the logical destination is assigned is connected, and for example, it is connected to the standard type logical destination corresponding part 3-0. If so, it is known that the transmission is by the withdrawal method. Then, it reads the contents of the read LD file (RLDF), which is not shown, and determines at which address in the data set (MSF) on the main memory the first data of the message data, for example, data 3-0A, is stored. Knowing this, read the data 3-0A. Also reads the contents of the serial number management file 6 and data 3-
A serial number is assigned to 0A, and the data is sequentially sent to the work station 8-0. For example, if it is connected to the completion-type logical destination correspondence unit 4-0, it knows that the sending is by the redundant sending method. Then, read the contents of the read LD file (RLDF) in the same way as above, find out in which data set (MSF) the first data 4-0K of the message data is stored, and read the data 4-0K. read. Also reads the contents of the serial number management file 7 and data 4-0.
A serial number is assigned to K, and the data is sequentially sent to the work station 8-0.

If the sending is by the drop-off method, that is, if it is sent from the standard type logical destination correspondence unit 3-0, etc., the sending of the message data 3-0A ends normally, as shown in FIG. Read LD File (RLDF) mentioned above without waiting for
The contents of the message data 3-0B are updated to the storage address of the next message data 3-0B, the contents of the above-mentioned serial number management file 6 are incremented by 1, and the process waits for transmission completion. When the transmission is completed, irrespective of whether it has ended normally or not, the transmission is completed and the next message data 3-0B is immediately sent.

Further, if the transmission is by the redundant transmission method, that is, if it is transmitted from the completion type logical destination correspondence section 4-0, etc., the process immediately enters the waiting state for transmission completion, as shown in FIG. When the transmission is completed, confirm that it has completed normally, and transfer the contents of the read LD file (RLDF) mentioned above to the next message data 4.
-0L is updated to the storage address, and the content of the above-mentioned serial number management file 7 is incremented by 1, indicating that it has been sent, and the next message data 4-0L is sent. Of course, in this case, if the message data 4-0K is not transmitted normally, it is necessary to wait until the message data returns to normal.

As explained above, according to the present invention, message data to be sent is either connected to the standard type logical destination correspondence section 3-i or completed type logical destination correspondence section 4-j.
It is possible to arbitrarily select whether to connect to the sender or the redundant sender. For this reason, for example, when transmitting using the drop-off method, if it is determined that certain message data cannot be received due to a failure, an operator on the receiving side generally intervenes and issues a retransmission request. However, if you specify the redundant sending method, this problem will disappear. Furthermore, when sending by the redundant sending method, the sending of the entire message may be delayed, but if the skipping method is specified, this problem will disappear.
