Abstract

PURPOSE:To realize the telegraphic message transmission control system in which the length of the telegraphic message is divided to be a prescribed value or below and sent, the line occupancy rate is reduced to enhance the immediacy. CONSTITUTION:An initial telegraphic message collated from a terminal equipment is received to generate one document (step 1), the initial telegraphic message is compared with a predetermined allowable text length, the telegraphic message up to the allowable length is sent, and the telegraphic message in excess of the allowable length is divided as a usual intermediate log record and stored (step 2). When the telegraphic message subject to collation has a remain after the transmission, a point intermediate log record and a shop dependent telegraphic message management record are stored, a succeeding telegraphic presence flag is set and then the processing is terminated (step 3). Second and succeeding collation is implemented by allowing the terminal equipment to recognize the flag and the remaining telegraphic message is sent.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message transmission control system, and more particularly to a message transmission control system that reduces line occupancy when transmitting long messages.

0002

[Prior Art] Conventional message transmission control systems, when transmitting long messages such as online inquiry transactions, send all messages using one data link. is now occupying the line. For example, if a 5000 BYTE message was sent over a 2400 BPS line, it would take approximately 16 seconds to complete the transmission of the entire message.

0003

[Problems to be Solved by the Invention] In the conventional message transmission control method described above, the line is occupied by a specific terminal for approximately 16 seconds until the transmission of all messages is completed, resulting in a long wait for inquiries from other terminals. There is a problem in that the service is not immediately available.

[0004] An object of the present invention is to provide a message transmission control system that can construct a system in which the length of the message is divided into parts equal to or less than a certain value, thereby reducing line occupancy and increasing immediacy. be.

[0005]

[Means for Solving the Problems] The message transmission control method of the present invention is such that when the message length of the first message received from a terminal exceeds a predetermined allowable message length, the first message that received the inquiry is changed to an acceptable message. The message is divided into a plurality of messages in units of length, and the plurality of messages are sent one by one each time there is an inquiry from the terminal.

[0006] The message transmission control system of the present invention includes a ledger creating means for receiving an initial message inquired from a terminal and creating one ledger, and comparing the first message with a predetermined allowable message length to determine the acceptable message length. It has a transmission means for transmitting a message up to the length of the message, and a division storage means for dividing and storing the part exceeding the allowable message length as an intermediate total record, and the division storage means divides and stores the part exceeding the allowable message length as an intermediate total record, The configuration is such that the intermediate total record that has been divided and stored by the storage means is read and the corresponding message is transmitted using the transmission means.

[0007]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The gist of the present invention is to divide the conventional method of transmitting the entire message in one transaction into a plurality of transactions, and to transmit messages for each range of allowable message length. FIG. 3 is a record structure diagram for holding output messages over multiple transactions in order to implement the present invention. Normally, a message that exceeds the allowable message length range is stored in the normal intermediate summary record shown in Figure 3 (D), and only when a heading part exists in the message, it is stored in the headline intermediate summary record shown in Figure 3 (C). Store. Then, both records are managed by the point intermediate total record shown in FIG. 3(B) by holding the database keys of both records. Furthermore, the point interim tally record shown in FIG. 3(B) is managed by the store-specific message management record shown in FIG. 3(A) holding the database key of the point interim tally record shown in FIG. 3(B). . Further, the distance to which the message has been transmitted is managed by the passing points in the intermediate point total record shown in FIG. 3(B).

Next, the operation will be explained.

FIG. 1 is a flowchart illustrating the operation of receiving a first message according to an embodiment of the present invention.

If the inquiry from the terminal is the first message, first, in step 1, a data image for one form is created. Next, in step 2, messages exceeding the allowable message length are stored in the "normal intermediate tally record", and messages within the allowable range are transferred to the transmission area. Next, in step 3, it is determined whether or not the inquiry has been completed, and only if there is a message that exceeds the allowable range, the "interim point tally record" and "store-specific message management record" are stored, and if there is a follow-up message. Set the flag and end the transaction. FIG. 2 is a flowchart illustrating the operation when the terminal recognizes the flag indicating that there is a continuation message and a second or subsequent inquiry message comes up.

[0012] First, in step 4, the ``store-specific message management record'' and the ``point interim tally record'' are read. Next, in step 5, if there are any remaining created forms, the "normal intermediate total record" is read and transferred to the transmission area. Also, if there are no remaining created forms,
After reading the "heading intermediate summary record" and creating a data image for one form, the same process as step 2 shown in FIG. 1 is performed. Further, in step 6, only when there is a message exceeding the allowable range, the ``point interim tally record'' and the ``store-specific message management record'' are stored, a flag indicating that there is a subsequent message is set, and the transaction is ended. Thereafter, the process returns to step 4 and the same process is repeated until there are no more unsent messages.

According to the present invention, for example, 5000 BYTE
If you send a message using a 2400 BPS line, 1
If the allowable amount of messages to be sent per session is 400 BYTE,
The time that a specific terminal occupies the line at one time is approximately 1.3
seconds.

[0014]

[Effects of the Invention] As explained above, the present invention reduces the line occupancy rate and improves immediacy by dividing the message transmission when the message length exceeds a predetermined allowable message length. It has the effect of being able to build an improved system.
