JPH03181297A - Identification code setting system for communication equipment - Google Patents

Abstract

PURPOSE:To vary an identification code as required by revising a identification code stored in a communication equipment when a key entry signal and a password are coincident. CONSTITUTION:An identification code written in an identification code storage means 2 is read by an instruction from a key entry means 1 to a control means 3 and the control means 3 controls a transmission reception means 5 to implement communication. In the normal operation, an identification code storage means 2 is not rewritten but when a request to change the identification code exists and the signal by the key entry means 1 and the password of the cryptographic storage means 4 are coincident, the identification storage means 2 is rewritten. Thus, the identification code is not rewritten without notifying the content of the cryptographic storage means 4 to lots of unspecified users and a manufacturer familiar with the content of the cryptographic storage means 4 can easily rewrite the identification code.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a setting method for a storage means in which an identification code is stored in advance in order to provide functions such as one-select calling in a communication device having a key input means. [Summary of the Invention] In a communication device that has an identification code and has various functions such as one-select call, there are cases where it is desired to change the identification code as necessary. The present invention allows the identification code to be substantially changed without replacing the dedicated storage means in which the identification code is stored as in the conventional case.

To this end, the present invention separately provides a means for storing a code in the communication device, and configures the communication device system so that when the signal input by key input and the code match, the identification code stored in the communication device can be changed. This is what I did.

[Conventional technology]

Since the identification code must not be easily rewritten while the 9 communication device is being operated, a read-only storage means storing the identification code is used and installed in the device. Therefore, it is necessary to replace the read-only storage means each time the identification code is changed.On the other hand, since the identification code often has different contents for each user,9 the communication device must be adapted to each individual user. Supply side (
This has the disadvantage of increasing the burden on manufacturers (manufacturers).

[Problems and Means to be Solved by the Invention] The prior art has a drawback in that it is necessary to replace the dedicated storage means every time the identification code is changed. According to the present invention, the communication device is provided with a means for storing a separately predetermined code, and when the signal inputted by the key input means matches the stored code.

The system was configured to allow the identification code to be changed.

〔Example〕

FIG. 1 is a block diagram showing the overall configuration of the present invention,
1 is a key input means, 2 is an identification code storage means, 3 is a control means, 4 is a code storage means, and 5 is a transmitting/receiving means. The control means 3 controls the transmitting and receiving means 5 to perform a communication operation.

In normal operation, the identification code storage means 2 is not changed by 1 degree, but when there is a request to change the identification code, when the key input means 1 and the code storage means 4 match,
It is assumed that the identification storage means 2 is rewritten as σ). FIG. 2 shows an example of the key arrangement of the key input means 1. As an example of the setting of the code storage means 4, it is assumed that when five keys in the key input order "C to 0*-C" match, the identification storage means 2σ) is rewritten and started or stopped. [Effects of the Invention] By providing the code storage means 4, it is possible to rewrite the identification code storage means 2 that stores the identification code, and only a specific operator can input the key input means 1 by key operation in a special pattern. Since it can be realized, it cannot be easily rewritten unless the cryptographic storage means 4 is made known to an unspecified number of users who use one device. Conversely, code storage means 4
Device suppliers (manufacturers) who are familiar with the contents of the system have the advantage of being able to easily rewrite the identification code.
