In recent years, as shown in FIG. 5, a mobile phone (hereinafter simply referred to as a mobile phone) 1 compatible with a SIM (Subscriber Identity Module) card 1 is brought into the cabin 2 a of the automobile 2, and the SIM card 3 is attached to the mobile phone 1. Then, a wireless communication link by Bluetooth (Bluetooth is a registered trademark) is established between the mobile phone 1 and a SIM card compatible automobile telephone (hereinafter simply referred to as an automobile telephone) 4 and authentication by a PIN (Personal IDentification Number) code is performed. If the result is positive, the cellular phone 1 reads the telephone ID (IDentification) stored in the SIM card 3 from the SIM card 3 and transfers it to the automobile phone 4, and the automobile phone 4 is transferred from the cellular phone 1. The thing which transmits using telephone ID is considered. According to this, it is possible to seamlessly shift from a call using the mobile phone 1 to a call using the automobile phone 4.
[0003]
By the way, the case where the mobile phone 1 is owned by another person and the automobile phone 4 is owned by the user is assumed. In this case, even if the other person attaches the other person's SIM card 3 to the mobile phone 1, if the authentication result by the PIN code is positive, the other person's mobile phone 1 moves from the other person's SIM card 3 to the SIM card. 3 is read out and transferred to the user's own car phone 4, and the user's own car phone 4 can make a call using the phone ID transferred from another person's mobile phone 1. As a result, in such a case, the user's own automobile telephone 4 is used by others without permission, and there is a problem that the user feels uncomfortable.
[0004]
The present invention has been made in view of the above-described circumstances, and the purpose of the present invention is to prevent the user's own car phone from being used by others, and the user feels uncomfortable. It is an object of the present invention to provide a telephone system that can avoid this problem.
[0005]
[Means for Solving the Problems]
According to the telephone system described in claim 1, the mobile phone reads the telephone ID stored in the IC card from the IC card, transfers the read telephone ID to the automobile telephone, and the automobile telephone is transferred from the cellular phone. In a telephone system configured to make a call using the transferred telephone ID and make a call using the telephone ID read from the IC card when the IC card is mounted, for identifying an individual A storage medium storing a personal identification ID different from the telephone ID is used, and the same personal identification ID as the personal identification ID stored in the storage medium is stored in the IC card. .
[0006]
Then, when the IC card is attached to the mobile phone , the mobile phone reads the personal identification ID stored in the IC card from the IC card, and the personal identification ID reading means reads from the storage medium to the storage medium. When the stored personal identification ID is read and the authentication result between the personal identification ID read from the IC card by the mobile phone and the personal identification ID read from the storage medium by the personal identification ID reading means is positive, the automobile The telephone is permitted to make a call using the telephone ID transferred from the mobile phone. On the other hand, the personal identification ID read from the IC card by the mobile phone and the personal identification ID reading means read from the storage medium. If the authentication result with the personal identification ID is negative, it is prohibited for the mobile phone to make a call using the telephone ID transferred from the mobile phone. It was configured to be.
[0007]
Therefore, the user stores in the IC card the same personal identification ID as the personal identification ID stored in advance in the storage medium, reads out the personal identification ID stored in the IC card from the mobile phone, and stores it. By causing the personal identification ID reading means to read the personal identification ID stored in the medium, it is possible to make a call using the telephone ID transferred from the mobile phone using the automobile telephone.
[0008]
On the other hand, even if another person tries to use the user's own car phone, if there is no storage medium storing a personal identification ID for identifying the other person, the personal identification ID for identifying the other person is also an IC card. If the ID is not stored, the personal identification ID is not authenticated, and the authentication result of the personal identification ID is rejected. Therefore, another person cannot use the user's own mobile phone. In this way, it is possible to prevent the user's own car phone from being used by another person and to prevent the user from feeling uncomfortable.
[0009]
According to the telephone system described in claim 2, since the storage medium is a driver's license and the personal identification ID is a driver's license number, it is common to carry a driver's license when driving a car. Therefore, by using the driver's license as the storage medium and using the driver's license number as the personal identification ID, it is not necessary to prepare another storage medium for storing the personal identification ID. The proof can be used effectively.

[0019]
When the power is on, the car phone 15 determines whether the SIM card 12 is inserted in the slot (step S1) and establishes a wireless communication link by Bluetooth with the mobile phone 11 It is determined whether the power condition is satisfied (step S2).
[0020]
Now, when the mobile phone 15 is in a position where the mobile phone 1 is close and a condition for establishing a wireless communication link by Bluetooth with the mobile phone 11 is satisfied (“YES” in step S2), A wireless communication link by Bluetooth is established with the mobile phone 11 (step S3). Then, the automobile phone 15 transmits a “PIN code signal” including a PIN (Personal Identification Number) code to the mobile phone 11 (step S4, see P1 in FIG. 4).
[0021]
When the “PIN code signal” is received from the mobile phone 15 (“YES” in step T1), the mobile phone 11 authenticates the PIN code included in the received “PIN code signal” (step S1). T2). If the authentication result is positive (“YES” in step T3), the mobile phone 11 transmits a “PIN code authentication confirmation signal” indicating that the authentication result is positive to the mobile phone 15 (step T4). , See P2 in FIG. 4).

Next, when the “authentication confirmation signal” is received from the mobile phone 11 (“YES” in step S7), the car phone 15 transmits an “authentication data request signal” to the mobile phone 11 to request authentication data. (Step S8, see P5 in FIG. 4).
[0025]
When the “authentication data request signal” is received from the car phone 15 (“YES” in step T9), the mobile phone 11 receives an “authentication data confirmation signal” to notify that the “authentication data request signal” has been received. Is transmitted to the mobile phone 11 (step T10, see P6 in FIG. 4). Then, the cellular phone 11 reads the driver's license number from the SIM card 12 (step T11), encrypts the read driver's license number, and generates driver's license number encrypted data (step T12). Then, a “driver's license number encrypted data signal” including the generated driver's license number encrypted data is transmitted to the automobile telephone 15 (see step T13, P7 in FIG. 4). Here, the authentication data is driving license number encrypted data.
[0026]
Next, the car phone 15 receives the “authentication data confirmation signal” from the mobile phone 11 (“YES” in step S9), and receives the “driver's license number encrypted data signal” from the mobile phone 11 ( "YES" in step S10), the driver's license number encrypted data included in the received "driver's license number encrypted data signal" is decrypted (step S11), and the driver's license number is restored. (Step S12).
[0027]
Here, it is assumed that the user is wearing the IC card driver's license 14 in the IC card reader 22. When the IC card driver's license 14 is attached, the IC card reader 22 reads the driver's license number stored in the IC card driver's license 14 from the IC card driver's license 14 and reads the read operation. The license number is output to the automobile telephone 15, and the automobile telephone 15 inputs the driver's license number from the IC card reader 22 (step S13).
[0028]
Then, the car phone 15 receives the restored driver's license number, that is, the driver's license number stored in the SIM card 12 and the driver's license number input from the IC card reader 22, that is, the IC card driver's license. The driver's license number stored in the certificate 14 is authenticated (step S14). Here, if the authentication result is positive (“YES” in step S15), the automobile telephone 15 transmits a “telephone ID request signal” to the mobile telephone 11 to request a telephone ID (step S16, FIG. 4). Medium P8).
[0029]
When the “telephone ID request signal” is received from the automobile telephone 15 (“YES” in step T14), the mobile phone 11 reads the telephone ID from the SIM card 12 (step T15), and the read telephone ID is read. Encryption processing generates telephone ID encrypted data (step T16), and transmits a "phone ID encrypted data signal" including the generated telephone ID encrypted data to the automobile telephone 15 (step T17, FIG. (See page 9 of 4).
[0030]
Next, when the “phone ID encrypted data signal” is received from the mobile phone 11 (“YES” in step S17), the car phone 15 is included in the received “phone ID encrypted data signal”. The encrypted telephone ID data is decrypted (step S18), and the telephone ID is restored (step S19). Thereafter, the automobile telephone 15 performs a calling process using the restored telephone ID (step S20).
[0031]
When the SIM card 12 is installed in the slot ("YES" in step S1), the car phone 15 does not perform the calling process using the phone ID transferred from the mobile phone 11 thereafter. The telephone ID stored in the SIM card 12 is read from the SIM card 12, and the normal call processing is performed using the read telephone ID (step S21).
[0032]
As described above, according to this embodiment, the driving stored in the IC card driving license 14 is performed using the IC card driving license 14 in which the driving license number for identifying the individual is stored. The same driver license number as the license number is stored in the SIM card 12, and the authentication result of the driver license number read from the IC card driver license 14 and the driver license number read from the SIM card 12 is If it is positive, the mobile telephone 15 is permitted to make a call using the telephone ID transferred from the mobile telephone 11, and in contrast, the driver's license number read from the IC card driver's license 14 and the SIM If the authentication result with the driver's license number read from the card 12 is negative, the car telephone 15 is prohibited from making a call using the telephone ID transferred from the mobile telephone 11. Form was.
[0033]
Therefore, the user stores in the SIM card 12 the same driving license number as the driving license number stored in the IC card driving license 14 in advance, and the driving license number stored in the SIM card 12. Is read by the mobile phone 11 and the driver's license number stored in the IC card driver's license 14 is read by the IC card reader 22. It is possible to make a call using the ID.
[0034]
On the other hand, even if another person tries to use the car phone 15, if the IC card driver's license 14 in which the driver's license number for identifying the other person is not prepared, the driver's license for identifying the other person is also prepared. If the number is not stored in the SIM card 12, authentication of the driver's license number is not performed, and the authentication result of the driver's license number is rejected. Therefore, another person cannot use the car phone 15. . In this way, it is possible to prevent the user's own car phone 15 from being used by another person and to prevent the user from feeling uncomfortable.
[0035]
In this case, the IC card driver's license 14 is used as a storage medium, and the driver's license number is used as a personal identification ID for identifying an individual. Since it is common to carry a certificate, it is not necessary to prepare another storage medium for storing the personal identification ID, and the driver's license can be used effectively.
