Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone terminal registration method for making a call by registering a user's mobile telephone terminal with a business operator in public mobile communication.

[0002]

2. Description of the Related Art In public mobile communication, a business operator receives a call request from a user's mobile telephone terminal, and after the mobile telephone terminal ends the call, in order to charge the mobile telephone terminal for the usage telephone bill. , The mobile phone terminal needs to be accurately identified. Telephone terminals in general public communication are
A communication line is wired from the relay station for each telephone terminal, and when the receiver of the telephone terminal is picked up, a current flows through the communication line,
It is identified that the telephone terminal is trying to make a call. However, since the mobile terminal wirelessly communicates with the relay station, it is not possible to identify which terminal it is by simply operating the handset of the mobile telephone terminal. Therefore, it is necessary to send some identification signal from the terminal by operating the terminal. On the phone
For the time being, a 10-digit telephone number is assigned. However, if the telephone number is directly used as the identification number,
A suitable 0-digit number is sent to the relay station so that the numbers of others can be used without permission. Therefore, a mobile telephone terminal requires a special identification number.

Under these circumstances, the mobile telephone terminal requires the authentication information and the manufacturing number as the identification number in addition to the telephone number. The authentication information is usually given to each terminal as the one corresponding to the telephone number, and the read-only memory (ROM) of the terminal together with the manufacturing number.
Is written in. When a call is made, that is, when the call button is pressed after inputting the telephone number of the other party into the ten-key pad, the manufacturing number is transmitted to the relay station, and the terminal to make a call is tentatively recognized. From the serial number, the relay station searches the authentication information of the terminal from the correspondence table created in advance, performs the calculation based on the authentication information between the relay station and the terminal, and recognizes the terminal. Is. As a result, there is almost no chance of unauthorized use by impersonating another person's terminal.

[0004]

For these reasons,
In order to use the public mobile communication service, it is necessary to write a telephone number, a manufacturing number and authentication information in the ROM in the terminal. FIG. 12 is a diagram showing a conventional mobile telephone terminal registration method. In the figure, the business operator is the manufacturer 11
The terminal with the serial number written at the time of manufacturing from 1 is purchased and stored. Then, when the application contents are sent from the agent 114 at the request of the user 115, the business operator writes the authentication information and the telephone number in the registration machine at the distribution center 112 (113), and the user 11
5 is to send the terminal. Therefore, after the contractor makes an application, the business operator authenticates the contractor, then writes the phone number and authentication information to the terminal, and the terminal is handed to the contractor. It took a few days to reach the person who purchased it, and it did not meet the needs of customers who wanted to use it immediately after purchasing it.

As a countermeasure against this, as shown in FIG. 11, each business operator installs a registration machine 113 that reads and writes a telephone number and authentication information in some of the agents 114, and sends contractor information to the business operator. When the authentication is successful, a method of sending the telephone number and the authentication information from the registration machine 113 to the terminal via the telephone line has been adopted. By installing a registered machine as an agent, we can respond quickly to customers, accept charges after that, respond to failures, increase sales of accessories due to increased number of customer visits, new visits by customer introduction / word-of-mouth etc. There is a strong demand for the setting of registered machines to increase the number of people. However, if you set up a registration machine at an agent, you may feel uncertain about whether or not a terminal can be duplicated, and if a duplicate is created, it may damage the reputation of the operator. There's a problem.

Therefore, as shown in FIG. 10, a business operator purchases a terminal in which a manufacturing number is written at the time of manufacture from a maker, and a terminal in which authentication information and a telephone number are registered in advance by a registration machine is a part of a reliable agent. A user who wholesales to a store and purchases the terminal from the agent can immediately use the terminal by notifying the business operator. However, in this method, since the telephone number has already been written, the user cannot select the desired telephone number, and only the terminal in stock at the agency can be opened immediately, so the desired terminal can be used immediately. It doesn't meet the customer's need to do it. In addition, if the telephone number is registered and sent to an agent, if the terminal is lost during the distribution process, there is a problem that the telephone number becomes an empty number, which is inconvenient. In addition, it is not possible for an electric home appliance mass retailer or an agent who does not have a registration machine, or an electric home appliance mass retailer or an agent who cannot prepare a terminal in which authentication information and a telephone number are registered in advance, to register immediately. It has been demanded to meet the demands of customers at the stores of such stores. In view of the above-mentioned drawbacks of the prior art, the present invention provides an immediate mobile telephone terminal even if a registration machine is not installed and a terminal in which a telephone number and authentication information are registered in advance cannot be prepared. It is intended to provide a registration method that can be used.

[0007]

Register the telephone number and the authentication information corresponding to the sequence number of the terminal. In addition, when the telephone number selected by the contractor is manually written in the terminal and a writing process for writing a check digit is provided,
By writing the check digit, it is calculated whether the correct telephone number has been input in the terminal, so that the incorrect writing of the telephone number is prevented. Also, if the mobile phone terminal is configured with an erasing process for erasing the sequence number and the manually input write key when the registration is completed, the registration work cannot be performed again, so that the same terminal is erroneously double-registered. Moreover, it is possible to prevent illegal writing of the telephone number. In addition, if it is configured to recognize whether the phone number is correct or incorrect when writing the phone number, or to recognize whether the handwriting key, phone number, check digit, etc. are correct, by displaying it on the display unit of the terminal. Accurate writing can be performed because the number recognition or the transition of the number being written can be confirmed by looking at the display.
