Abstract

PURPOSE:To execute efficiently the retrieval of a text by giving a transmission/ reception serial number to reception/transmission information at each terminal device every time a text is received and transmitted so as to store the result to a transmission/reception mapping file. CONSTITUTION:When a text reception proceeding program 51 receives a text from a line 1, it is stored in a text storage file 61 and the text is stored in a text reception information section 631 of a transmission n/reception mapping file 63 while being added with a reception terminal number and a reception serial number. Then a text transmission program 52 extracts a text from a text storage file 61 and transmits it to a destination terminal device. When the transmission is finished, a transmission, end processing program 53 is started and the text is stored in a retransmission index file 62 and a transmission information section 632 of the transmission/reception mapping file 63 while a transmission terminal number is added. Thus, when a text retrieval command from a terminal device comes, the mapping file 63 is retrieved by using the terminal number as a key so as to extract transmission/reception information immediately.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a message exchange system, and in particular, a method for efficiently determining whether the message exchange system has correctly transmitted a message received from a sending terminal to a destination terminal. Concerning a searchable message search method.

BACKGROUND OF THE INVENTION In recent years, with the remarkable development of computer and communication technology and the progress of the information society, there has been an increasing demand for a new type of communication network that organically combines computers and communication.

This is called a value-added communication network (so-called VAN), and provides users with various application services in addition to conventional transmission services.

One such service is a message search service, which provides a means to check whether the message sent by the user is correct and has reached its destination.

Conventionally, such services were provided only to network operators, but because they were not often used, there was currently no need for efficient searches.

However, in recent years, the number of users requesting such services has increased, and since these services target an unspecified number of users, a technique for efficiently conducting message searches has become necessary.

[Conventional technology]

Figure 3 is a block diagram showing an example of the configuration of a general message exchange system, Figure 4 is a diagram schematically showing the flow of message exchange processing, and Figure 5 is a diagram showing a retransmission index file. FIG. 3 is a diagram showing the format of one entry (block).

In FIG. 3, 1 is a line, and 2 is a line corresponding section.

3 is a line scanning section, 4 is an exchange control section, and 5 is a storage device.

6 is a file memory.

First, by initial program loading (IPL) executed when the power is turned on, a program necessary for message exchange processing, such as the message reception processing program 51. Message transmission processing program 52. Transmission completion processing program 5
3 etc. are loaded from the file memory 6 to the storage device 5.

When the loading is completed, the exchange control unit 4 executes the above program to control the line scanning unit 3 to scan each line corresponding unit 2 and to transmit and receive messages from each line 1 in a time-sharing manner. state. The operation of message exchange processing according to the conventional method will be explained below with reference to FIG.

In the state where a message can be sent and received from vA1 each time, the message reception processing program 51 edits the received message into a format that can be stored in the message accumulation file 61, stores it in the message accumulation file 61, and at the same time A control block related to the message is input into the queue 54 provided in the specific area No. 5. [Figure 4 ■
Reference] Next, the message transmission processing program 52 sends the message to the queue 54.
The control block is read from the control block, and the message corresponding to the control block is stored in the message storage file 61 of the file memory 6.
After editing it into a format that can be transmitted to the destination line, the data is sent to the destination via the line corresponding section 2 selected by the line scanning section 3 under the control of the exchange control section 4. [See FIG. 4 (■)] The above two processes are executed in a time-sharing manner (so-called multitasking).

When the transmission of the message is completed, the transmission completion processing program 5
3 is started, and the program writes one entry (block) of message reception information and message transmission information into the retransmission index file 62 provided in the file memory 6.
The file is edited and stored in the format shown in FIG. [See Figure 4 ■] In this case, the transmission/reception information is stored in the retransmission index file 62 having a certain area every time transmission is completed, and when the area of the retransmission index file 62 becomes full, the data is stored in the retransmission index file 62 using the so-called round tropin method. Since the data is stored repeatedly in an overpainting format, returning to the start address, old information is sequentially erased.

[Problem that the invention seeks to solve]

Therefore, in the conventional system, only the message reception information and message transmission information corresponding to the message that has actually been sent to the destination are retransmitted in a predetermined area in the format shown in Figure 5 above. Since the correspondence between the message sent by the user and the message actually sent to the destination cannot be uniquely determined, a message search command is input from the user terminal to retrieve the corresponding message. When searching the index file 62 for retransmission according to the "receiving terminal number", "receiving terminal serial number", "reception date, hour, minute", etc. indicated by the parameters of the command, the above "receiving terminal number" + "receiving terminal serial number" It is necessary to search sequentially from the start address of the file using the key as the key, and it takes a lot of time to search, and if it has not been sent to the recipient yet, it is not registered in the file, so it is not always possible to search. In the worst case, it is necessary to dump the index file 62 for retransmission and search manually, which requires a huge amount of man-hours and there is a risk of search errors. there were.

In view of the above-mentioned conventional drawbacks, the present invention provides a search file that is not supported at the user end, and also ensures that there is a one-to-one correspondence between the message sent by the user and the message sent to the destination, so that the message is immediately correct. The purpose of this is to provide a method that allows you to obtain the information necessary to know whether or not the message has been sent to the other party.

[Means for solving problems]

The purpose of this is to provide a means to store the received message in a message storage file when a message is received from one line, and to retrieve the message from the message storage file and send it to the other party when sending a message to another line. In a message exchange system having a means for storing transmission information in a retransmission index file at the time of transmission, means for storing the received message in a message accumulation file and at the same time storing the reception information in a transmission/reception mapping file; At the time of completion, a means is provided to store the transmission information in the index file for retransmission and at the same time to store it in the transmission/reception mapping file, and by searching the transmission/reception mapping file using the terminal number as a key, This can be achieved by the message search method of the present invention, which is capable of recognizing transmitted and received information related to messages.

[Effect]

That is, according to the present invention, a transmission/reception mapping file is provided which is not supported by the user end and which secures an area for storing transmission/reception information for each reception sequence number of a message. The message reception information and the message transmission information are stored independently for each block corresponding to the terminal number and the reception sequence number of the message at each point in time from when the transmission to the destination is completed. Therefore, when a message search command is received from a user, by looking at the entry in the above sending/receiving mapping file that corresponds to the terminal number and receiving serial number, the sending/receiving information can be retrieved immediately. This has the effect that it can be carried out efficiently.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 schematically shows the operation when message exchange processing is executed by implementing the present invention, and Fig. 2 shows one of the transmission/reception mapping files necessary for implementing the present invention. This shows an example of a formant for an entry.

In Figures 1 and 2, the same symbol 1 as in Figures 4 and 5.
Names, etc. indicate the same object.

When implementing the present invention and performing message exchange processing,
The overall operation is the same as that of the conventional method explained in FIG. 3, so a description thereof will be omitted, and here, the explanation will focus on the operation for the transmission/reception muffing file, which is the main focus of the present invention.

In the present invention, a transmission/reception mapping file 63 is provided in the file memory 6 shown in FIG. 3, which has a certain number of entry (block) areas corresponding to the number of serial numbers, in the format shown in FIG. 2, corresponding to each terminal. It is being

First, in FIG. 1, when the message reception processing program 51 running in the exchange control unit 4 receives a message from the line 1, it collects the message in a format that can be stored in the message storage file 61 and stores it in the file. At the same time, the message reception information 9 is stored in the message reception information section 631 of the transmission/reception mapping file 63.
For example, the receiving terminal number, receiving terminal serial number, etc. are stored. At this time, when the receiving serial number is updated, it is stored in the entry corresponding to the receiving serial number among a group of entries corresponding to the same receiving terminal number. (Refer to "■") ■Next, the message transmission processing program 52 retrieves the control block to be processed from the KEY 54 and sends the message corresponding to the control block using the same procedure as in the conventional method.
Retrieve the message from the message accumulation file 61 and send it to the other party's terminal 1.
Edit it into a format that can be sent to the recipient, and send it to the recipient.

■When the transmission of the message described above is completed, the transmission completion processing program 53 is started, and at the same time, the program stores the transmission information, such as the transmission terminal number, transmission terminal serial number, etc., in the retransmission index file 62 using the same procedure as in the conventional method. , the same transmission information as above is also stored in the message transmission information section 632 of the transmission/reception MA/7 pin file 63.

At this time, when the transmission serial number is updated, it is stored in another entry corresponding to the above-mentioned reception serial number among a group of entries corresponding to the same receiving terminal number. (See ■') In this way, the sending/receiving mapping file 63 provided in the file memory 6 is stored in the message receiving information section 631 and the maximum expansion corresponding to each terminal connected to this message exchange system. Areas in the message transmission information section 632 for the number of destinations (usually 16.32, etc.) are reserved for the number of serial numbers, and when the message reception information section 631 receives a message from the terminal, it stores the message transmission information. The feature of the section 632 is that transmission and reception information is stored in correspondence with the serial number at the time when the transmission of the message is actually completed for each destination.

Therefore, when a message has been received from the terminal but has not yet been transmitted, the message transmission information section 632 remains blank.

However, if the number of messages sent from one terminal exceeds the number of serial numbers on the sending/receiving mapping file secured in advance, the messages will be returned to the starting address and stored using the so-called round tropin method. In this case, old information remains in the area, and new transmission information is overwritten and stored.

By providing such a transmission/reception mapping file 63, when a message search is requested from a user terminal using a "telegram search" command, the exchange control unit 4 stores the transmission/reception mapping file 63 using, for example, the receiving terminal number. , by searching using the receiving terminal serial number 1 etc. as a key,
Transmission and reception information regarding the message sent by the terminal at that time can be immediately retrieved.

index file for retransmission 62. The message storage file storage address stored in the start address of each entry in the transmission/reception mapping file 63 is used when accessing the message storage file and retrieving the message.

〔Effect of the invention〕

As described above in detail, the message search method of the present invention provides a sending/receiving muffing file that is not supported by the user end and has an area for storing sending and receiving information for each receiving sequence number of the message. At each point in time, when the message is received and when the sending of the message to the other party is completed, the message is received for each professional terminal that corresponds to the receiving terminal number and the receiving sequence number of the message. Since the information and message transmission information are stored independently, when a message search command is received from the user, by looking at the entry in the transmission/reception mapping file that corresponds to the terminal number and reception sequence number, Transmitted and received information can be retrieved immediately, and message searches can be performed efficiently.
