The key operation unit 120 is also used as an input means for the user to input mail data, and a specification means for the user to specify subscriber identification information for making the communication control state active. .

In the mobile phone 10 having the above-described configuration according to the present embodiment, a plurality of different subscriber identification information (IMSI) is stored in the USIM card 122, and the mobile phone such as telephone and mail transmission / reception is used for the subscriber identification information (IMSI). Communication via the communication network 20 can be performed.
Hereinafter, in this embodiment, as an example, user A uses business identification information: IMSI (B) used by the company (corporate B) for work, and user A uses personal information other than work. A case will be described in which personal subscriber identification information: IMSI (A) used in the above is stored in the USIM card 122 of one mobile phone 10 and used.

Table 1 shows the relationship between subscriber identification number, telephone number, e-mail address, storage location, subscriber, user and application for the two subscriber identification information IMSI (A) and IMSI (B). . The subscriber identification information IMSI (A) in which the individual A is in the name of the subscriber is stored in the USIM card 122 attached to the mobile phone 10 and used for personal communication of the user A. Furthermore, the subscriber identification information IMSI (B) in which the corporation B, who is the work place of the individual A, is in the name of the subscriber is also stored in the USIM card 122 and used for business communication of the user A. The telephone number and mail address are uniquely assigned to each subscriber, and are stored in the USIM card 122 and the internal memory 112 for each subscriber identification information IMSI. Further, the USIM card 122 and the internal memory 112 store an authentication algorithm, telephone / address book information, and communication history information in association with the subscriber identification information for each subscriber identification information IMSI.

Next, a main part of a communication processing procedure when communicating using the mobile phone 10 having the above-described configuration will be described. Hereinafter, the following cases 1 to 4 will be described separately.
1. When the power is turned on with the user A's USIM card (A) attached (FIG. 3).
2. When the use of IMSI (B) of corporation B is stopped and the use is switched to using only IMSI (A) of user A (FIG. 4).
3. When the use of the IMSI (A) of the user A is stopped and the use is switched to the use of only the IMSI (B) of the corporation B (FIG. 5).
4). When the USIM card (A) of user A is removed, the USIM card (C) of another user C is inserted, and the power is turned on (FIG. 6).

  FIG. 3 is a sequence diagram showing an example of a communication processing procedure when the power is turned on in a state where the USIM card (A) 122 of the user A is attached to the mobile phone 10 having the above configuration. The communication processing procedure when the mobile phone 10 moves to another location registration management area after the power is turned on is the same communication procedure.

  In FIG. 3, first, when the user A turns on the power of the mobile phone 10 with his / her USIM card (A) attached, a predetermined amount is set between the mobile phone 10 and the base station 210 of the mobile phone communication network 20. The radio link establishment sequence is executed.

Next, the mobile phone 10 displays a screen that prompts the user to input a PIN number as authentication information for reading the business-use IMSI (B) stored in the USIM card (A). When the user operates the key operation unit 120 while viewing this display and inputs a predetermined PIN number, terminal level authentication processing is performed. The control unit 111 of the mobile phone 10 reads the IMSI (B) based on the authentication information input by the user and the PIN number as the verification authentication information stored in association with the IMSI (B). Determine if it is possible. Here, when both PIN numbers match and it is determined that reading is possible, the control unit 111 reads the business IMSI (B) stored in the USIM card (A).
The business-use IMSI (B) stored in the USIM card (A) may be controlled to be read without performing the authentication.

  Next, the mobile phone 10 uses the business-use IMSI (B) read from the USIM card (A) to the location registration / authentication device 240 of the base station in the location registration management area where the mobile phone 10 is located. The location information LAI is notified. Here, when TMSI is already assigned and stored in the mobile phone 10, the TMSI is read and used instead of the IMSI. When the VLR corresponding to the location information LAI received from the mobile phone 10 changes, the location registration / authentication device 240 registers the information on the new VLR in the HLR.

Next, a predetermined authentication / confidential processing sequence is executed between the mobile phone 10 and the location registration / authentication device 240.
The subscriber authentication is performed using a challenge-response method that does not use a password, for example, as follows. First, the location registration / authentication device 240 generates a random number (RAND) based on the IMSI (B) received from the mobile phone 10 and transmits the random number (RAND) to the mobile phone 10. The cellular phone 10 receives the numerical value of the random number (RAND) received from the location registration / authentication device 240, the unique authentication key Ki (B) stored in the USIM card (A) 122 together with the IMSI (B), and predetermined authentication. A cryptographic operation is performed using an algorithm to generate a signed response (SRES). Then, the mobile phone 10 transmits the generated response (SRES) to the location registration / authentication device 240. The location registration / authentication device 240 uses the numerical value of the random number (RAND) transmitted to the mobile phone 10, the unique authentication key Ki (B) corresponding to the IMSI (B), and a predetermined authentication algorithm. The encryption operation is performed in the same manner as in, and a response (SRES) is generated. Then, the location registration / authentication device 240 authenticates the subscriber (corporation B) by comparing the response (SRES) received from the mobile phone 10 with the response (SRES) generated in the device. When this authentication is successful, the location registration / authentication apparatus 240 executes a registration process related to the IMSI (B).
The secret communication is performed as follows, for example. After the authentication is successful and the user communication channel (link) between the mobile phone 10 and the location registration / authentication device 240 is established, the mobile phone 10 and the location registration / authentication device 240 each include the random number (RAND). The secret key Kc (B) used for the secret communication is generated using the above-described numerical value, the unique authentication key Ki (B), and a predetermined algorithm. This secret key Kc (B) is used for encryption of data moving on a wireless link (wireless interface) between the mobile phone 10 and the base station 210. For example, the mobile phone 10 encrypts data to be transmitted (plain text) using the secret key Kc (B) and a predetermined secret algorithm. Then, the location registration / authentication device 240 or the base station 210 decrypts the received encrypted data using the secret key Kc (B) and a predetermined secret algorithm, and returns it to plaintext data.

  Next, in order to ensure anonymity of communication, a sequence for assigning a new TMSI is executed between the mobile phone 10 and the location registration / authentication device 240. First, the location registration / authentication apparatus 240 generates and assigns a new TMSI ′ (B) in association with the IMSI (B) of the corporation B. Then, the location registration / authentication apparatus 240 transmits a new TMSI '(B) to the mobile phone 10 using the above-described secret communication channel. The cellular phone 10 stores the new TMSI ′ (B) received from the location registration / authentication device 240 in a predetermined storage area of the internal memory 112 or the USIM card (A) 122 in association with the IMSI (B). Then, the mobile phone 10 notifies the location registration / authentication apparatus 240 that the assignment of the new TMSI '(B) has been completed.

  Next, the location registration / authentication device 240 transmits to the mobile phone 10 a location registration response notifying that location registration has been completed for the IMSI (B) of the corporation B out of the two subscriber identification information of the mobile phone 10. To do. Then, a link disconnection sequence is executed between the mobile phone 10 and the location registration / authentication device 240.

After the authentication and location registration for the IMSI (B) of the corporation B are completed, authentication and location registration are subsequently executed for the IMSI (A) of the individual A.
First, when the mobile phone 10 detects the installation of the USIM card (A) 122 of the individual A when the power is turned on, the mobile phone 10 reads the personal IMSI (A) stored in the USIM card (A) 122. A screen prompting the user to input a PIN number as authentication information is displayed. When the user operates the key operation unit 120 while viewing this display and inputs a predetermined PIN number, terminal level authentication processing is performed. The control unit 111 of the mobile phone 10 reads the IMSI (A) based on the authentication information input by the user and the PIN number as the verification authentication information stored in association with the IMSI (A). Determine if it is possible. Here, when it is determined that both PIN numbers match and can be read out, the control unit 111 uses the control unit in the USIM card (A) 122 to store the personal information stored in the USIM card (A) 122. Read IMSI (A).

  Next, for the personal IMSI (A), the location registration processing, authentication / confidential processing, and new TMSI (A) allocation processing are executed. Note that the contents of these processes are the same as those in the case of the above-mentioned business-use IMSI (B), and thus description thereof is omitted. However, information such as a key, an algorithm, and TMSI (A) is stored not in the internal memory 112 but in a predetermined storage area in the USIM card (A) 122.

  Next, a link disconnection sequence is executed between the mobile phone 10 and the location registration / authentication device 240. Finally, a radio link disconnection sequence is executed between the mobile phone 10 and the base station 210.

  Through the above communication sequence, the user A can use the telephone function for both the personal telephone number and the business telephone number in the cellular phone communication network 20 of the subscribing telecommunications carrier, E-mails can be sent and received for e-mail addresses and business e-mail addresses.

When making a call or sending an e-mail using the mobile phone 10, the initial setting is such that either the individual A IMSI (A) or the corporation B IMSI (B) is used as the source. Is set. When the user A performs an operation for switching the IMSI, the IMSI used when making a call or sending a mail is changed.
On the other hand, since the location registration is performed for both the IMSI (A) of the individual A and the IMSI (B) of the corporation B, both the IMSI ( Regarding A) and IMSI (B), signals and data can always be received from the mobile phone communication network 20 side.
Here, it is preferable to display the IMSI being used so that the user can always grasp the IMSI used for transmitting / receiving a telephone or mail in the mobile phone 10.

  When a personal telephone or mail is transmitted, a personal telephone / address book stored in the USIM (A) card 122 is used in association with the IMSI (A) of the individual A. On the other hand, when a business telephone or email is transmitted, a business telephone / address book stored in the USIM card (A) 122 or the internal memory 112 is used in association with the IMSI (B) of the corporation B. .

  Further, when sending / receiving a personal telephone or mail, the communication history information is provided in the USIM (A) card 122 or the internal memory 112 provided in association with the IMSI (A) of the individual A. Saved in the business communication history information file.
