Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a data storage system which is installed in each communication terminal connected to an exchange system and stores data read out and used when this terminal is used. The present invention relates to a data write control method for writing data to a device and rewriting the written data.

(Prior art) In the conventional data writing control method, when writing data to data storage means provided for each terminal via a communication line,
First, a write request signal requesting data writing is transmitted, and the data storage means of the terminal to which the data is to be written prepares for data writing. Since some of the data unique to each terminal is important or requires secrecy, it cannot be disclosed to the general public, so the write request signal includes a password unique to the terminal. Usually, a method is adopted.

(Problems to be Solved by the Invention) In this way, the conventional data write control method transmits a data write request signal with a password possessed by the terminal to the terminal to which data is to be written. Since the terminal is configured to call up the data storage means of the terminal to which data is to be written, it is necessary to change the password frequently from the viewpoint of data confidentiality. As a result, there has been a problem that complications and inconveniences cannot be avoided, such as an increase in the number of errors in memorizing password codes.

An object of the present invention is to solve this problem, simplify the procedure, and provide nine data write control methods.

(Means for Solving the Problems) The data write control system according to the present invention includes a gate means for connecting write data input via a communication line to a data storage means, and a call permission for opening the gate means and allowing the data to pass through. setting means is provided in the terminal, and when a call is received via the communication line, the communication line is connected to the data storage means via the gate means by operating the call permission setting means of the incoming terminal. t-Characteristics.

The data storage means 11 stores data for the ten terminals, and the data is read out and utilized when necessary for the operation of the terminal. The data writing setting means 12 has, for example, a function button for specifying data writing on the terminal. The data input means 13 is, for example, a three-piece keyboard having buttons and an electric key for inputting data into the data storage means 11 while the write setting means 12 specifies data writing. The line connection means 14 has a line interface section 141 that connects the communication line 30 and converts the signal transmission procedure of the line. The call permission setting means 15 instructs the gate means 16 to write the data transmitted via the communication line 30 into the data storage means 11 and to open the gate for a predetermined length of time to allow the data to pass through. The call permission gate means 16 receives the output of the line connection means 14 and the output of the data input means 13 as inputs, and has an input switching section 161 for selecting either one. The output of the input means 13 and the output of the line connection means 14 as specified by the call permission setting means 15 are selected and connected to the data storage means 11, respectively.

The input via the line connection means 14 is connected to the data storage means 11 to receive write data from the data input means of the other party's terminal. If call permission is not specified, write data sent from the other party's terminal will not be accepted.

Further, FIG. 1 shows only the components related to the reception of write data. When transmitting write data via a communication line, the conventional technology for transmitting write data can be used, so the line connection means on the called side only needs to be equipped with functions that match the transmitting means. Means related to transmission will not be illustrated and will not be described.
