JPS6010847A - Packing system in message transmission - Google Patents

Abstract

PURPOSE:To improve the data transmission efficiency by transmitting quickly data after the data is formed into a block through the indication of a user even if the data stored in a block is small. CONSTITUTION:When the user desires to transmit messages M1-Mn while the message are formed into blocks, the user gives an indication to a message transmitter 11. In this case, an N representing the midway of packing is designated to the messages M1-Mn-1 and an L representing the last of the packing is designated to the message Mn. The message transmitter 11 receiving the designation stores the message up to the messages M1-Mn-1 in a transmission buffer 13, and the messages M1-Mn are not formed into blocks and not transmitted until the message Mn is received.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a message transmission system, and more particularly to a system in which the user controls message blocking to improve data transmission efficiency during transmission.

(2) Prior Art and Problems Conventionally, as a message transmission method, multiple messages stored in a transmitting device are collectively transferred as one block. It had the disadvantage of poor transmission efficiency because it transmitted blocks of small amounts of data.

(3) Purpose of the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, and even when a small amount of data is stored in a block, it can be divided into blocks according to a user's instruction and transmitted quickly, thereby increasing transmission efficiency. And so.

(4) Structure of the Invention The object of the invention is to provide a message transmitting device that blocks a message and transmits the message, including a blocking instruction means for a user to instruct the message to be blocked, and a message stored in a transmission buffer based on information instructed by the blocking instruction means. This is achieved by a backing method for message transmission, which is characterized by providing means for transmitting messages in blocks.

(5) Examples of the invention The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a message transmitting device according to an embodiment of the present invention. In the figure, 11 is a message transmitting device, 12 is a data transmitting section, 13 is a transmission bag 7, and 14 is a message storage section. , 15 is a message input section. FIG. 2 is a flowchart showing one embodiment of the present invention and a soaking process.

Now, the user sends message J + M2,...
If you want to send a Mnn love block, you instruct the message transmitting device 11 to do so, but specifying that multiple messages are to be blocked in this way is called backing. For messages from M to Mn-1, 'N' (n
ot 1st), and for Mn, 'L' (last
). .

The message transmitting device 11 that received this designation is M.

Messages from to Mn-14 are stored in the Qj transmission buffer 13, and when Mn is received, V' is converted to pro7 from Ml to Mn and transmitted.

However, if the sending pan 7 buffer 131 is full by the time Mn is received, the messages received up to that point are transferred.

The above is limited to a single user, and is almost the same as blocking for input/output with normal external storage (for example, DA 8D).However, in the case of a communication system, the difference is that the data that is divided into two blocks is generally This means that it consists of messages from multiple users. Therefore, messages written using the backing method of the present invention are temporarily stored in the message storage section 14. The message thus stored is captured in the transmission buffer 13 of the data transmission section 12 and transmitted.

The message storage section 11 functions as a buffer between the user and the data transmission section 12. In other words, even if the data transmitter 12 is busy and cannot actually send a message immediately, the user can still input the message regardless.

Now, how the message transmitter 12 performs ノ(・nocking) will be explained below with reference to FIG.

The operation of the backing method in the data transmitter 12 is as follows.

■ Check to see if meso-sage storage unit 14 stores meso-sage, and if it is, go to ■.

nothing. If the message exceeds the sending buffer 13 (overflow), the messages stored up to that point in the sending buffer 13 are sent all at once without being captured.

Return to ■ ■ (If there is no message) Check to see if there is one that has specified 'L' (last) among the messages that have just been imported into the sending buffer 13. [(Including cases where no messages have been imported) Go to ■.

(Some messages specify I L l) Transfer all messages stored up to that point in the sending buffer 13 all at once.

Return to ■.

■ (If there is no message with IL+ specified) Wait for the message to arrive at the message storage unit 14, and return to ■ when it arrives. The above is an explanation of the backing method. The operations are ■, ■, and ■.

That is, 1w, basically l )l + / + L I
Regardless of the specification, as long as there are messages in the message storage section 14, messages will be captured until the transmission buffer 13 is full. However, the message storage section 14
Even if there are no messages, the number of transmissions can be reduced by waiting until there is a request for bulk transfer (specifying Zunawara L L l) from the user and loading as many messages as possible into the transmission buffer 13. , the overhead during transmission can be reduced.

Another important point is not to wait until the sending buffer 13 becomes full.

That is, even if there is no message in the message storage unit 14, if there is a message specified by the ILI in the transmission buffer 13, the message is transmitted. Therefore, there is no possibility that a message that should have been sent is not yet sent, resulting in a drop in processing efficiency.

(6) As described in detail, according to the present invention, more messages can be received by the message transmitting device V than in the conventional method, and transmission can be controlled according to user instructions, so data transmission efficiency can be improved. can be achieved.
