Description of the Related Art Conventionally, mobile communication terminal devices that perform information communication by connecting to a mobile communication network are used by connecting a portable electronic storage device such as an IC card. The portable electronic storage device stores communication setting information related to connection to the mobile communication network in advance, and connection to the mobile communication network is performed using the information. In such a mobile communication terminal device, communication setting information relating to connection to a mobile communication network is not held in the terminal device itself, and a mobile electronic storage device is connected to connect to the mobile communication network. It becomes possible.
[0003]
As a mobile communication network using such a mobile communication terminal device, GSM (Global Systems for Global Standard for European digital mobile communication) is used.
Mobile communications), DCS (Digital Communications Services) 1800, or North American digital mobile phone standard PCS (
Personal Communications Services) 1900 system. These systems use almost the same protocol except that the GSM system is used in the frequency band of 800 MHz, the DCS1800 system is 1800 MHz, and the PCS1900 system is 1900 MHz. For this reason, communication setting information related to the mobile communication network used for these is recorded in an IC card called a SIM (Subscriber Identity Module) card, and the SIM card can be attached to and detached from an interface provided in the mobile communication terminal device. .

FIG. 6 shows an external mechanical configuration and an internal logical configuration of the SIM card, respectively. As shown in FIG. 6A, the outer shape of the SIM card 1 is similar to that of a credit card or the like. An IC chip 3 is embedded in an electrically insulating synthetic resin substrate 2 and is electrically connected to a connection electrode 4 on the surface of the substrate 2. The connection electrode 4 is electrically connected so that the mobile communication terminal device and the IC chip 3 can be accessed in a state where the SIM card 1 is attached to an interface provided in the mobile communication terminal device. I do. In addition, a micro SIM in which the synthetic resin substrate 2 is formed only in a portion including the IC chip 3 and the connection electrode 4 to reduce the size is also used.
[0005]
As shown in FIG. 6B, the IC chip 3 is provided with a storage area 3m, which is divided into a communication area 5 and a user area 6. The communication area 5 stores communication setting information for connecting to the mobile communication network. User setting information is stored in the user area 6 as information that can be freely set by the user from the mobile communication terminal device and information that is updated according to the user's use in the mobile communication network. Is done. As the communication setting information, fixed information that cannot be changed by the user from the mobile communication terminal device, for example, the identification information of the communication carrier, the identification information of the individual contractor, the mobile electronic storage device itself Identification information and the like are stored. In addition, the priority of the communication network to be connected, the information of the communication network forbidden to connect, the mobile communication terminal device can be operated or changed, or the contents are automatically changed by the mobile communication terminal device. Information is also stored. The storage area 3m has a storage capacity of about several kilobytes to several tens of kilobytes as a whole.
[0006]
For example, in the case of the GSM system, IMSI (International Mobile Subscription) for identifying a subscriber and a registered mobile communication network is used as communication setting information.
Identity), GID1 / 2 representing group of cards (Group IDentifier level 1/2), PLMN (Public Land Mobile Network) indicating communication network priority
selector, Forbidden PLMN indicating a communication network that cannot be connected, and the like. The user setting information includes telephone number book, short message service setting information and message, dial history, and the like. These user setting information items are fixed, but the contents can be freely changed by the user. In the case of the GSM system, in the user area 6 of the SIM card 1 are MSISDN (Mobile Station International ISDN Number) which is the telephone number of the own station, and a user telephone number book.
Abbreviated Dialing Number, Last Dialing Number as dial history, Short Message, Short Message Service as Short Message Setting Information
There are Parameters.
[0007]
Since the portable electronic storage device such as the SIM card 1 shown in FIG. 6 stores information in accordance with the GSM standard, items that can be freely set as user setting information are fixed. In addition, the storage capacity is often not sufficient, and therefore a mobile communication terminal device configured to have a user data storage area that can be freely defined on the mobile communication terminal device side is also used. In such a mobile communication terminal device, the user can freely store more user phone number books, address books, short messages, etc. on the mobile communication terminal device side, It is also possible to store telephone numbers for services of telecommunications carriers as a fixed telephone directory.
[0008]
In addition, when a communication additional service provided by a communication carrier or a function newly supported by the communication network is used, the setting information related to the service is not defined as communication setting information or user setting information of the portable electronic storage device In addition, the mobile communication terminal device may have a function of holding the information. For example, in the case of a service for accessing the Internet, setting information such as a domain name server, a user ID, a network password, an e-mail server name, an e-mail address, an access user name to the server, a password, a GSM SIM card Some have a function of holding a telephone number for receiving data communication and facsimile communication that is not held.
[0009]
The mobile communication terminal device needs to be configured to be small and light as a whole. In order to make the mobile communication terminal device easy to use, it is necessary to efficiently store various information as described above. A prior art for storing multipurpose data using an IC card is disclosed in, for example, Japanese Patent No. 2609645 (Japanese Patent Laid-Open No. 1-174766). In this prior art, the memory area of the IC card is divided into a plurality according to the character of the data or usage, and a unique number is assigned to each area for management. Further, a plurality of definition information areas for storing information defining data storage areas are provided so that data can be used for multiple purposes.

Compared to the SIM card 1 or the like, a sufficient storage area can be provided on the mobile communication terminal device side, and the data structure and type can be freely determined. However, each piece of information is treated the same regardless of the communication setting information and user setting information held by the connected portable electronic storage device. For this reason, when using a portable electronic storage device that holds a plurality of different setting information, an e-mail server name, e-mail address, access user name and password for the server, a receiving telephone for data communication and facsimile communication in the GSM system It is necessary to select or re-enter information associated with setting information such as a number from a large amount of information stored in the mobile communication terminal device every time the portable electronic storage device is replaced. is there.
[0011]
In addition, if a history of a telephone number indicating the other party who has made a call through the mobile communication network is stored in the user area 6 in FIG. 6, the redial function can be used. Does not have an area for storing time information. If the specification is such that the telephone number history is stored on the mobile communication terminal side, the telephone number history including sufficient information such as time information can be used. However, when a plurality of users use the same mobile communication terminal device, different telephone number histories cannot be recorded for each user. It is necessary to continue using the same telephone number history or clear the entire telephone number history, and start using it without any history. Further, when data such as a telephone number book or an address book input by the user is stored on the mobile communication terminal device side, a plurality of users have different mobile communication terminal devices for each user. When the portable electronic storage device is mounted and used, it is possible to display all the data input by all users, making it difficult to select necessary data for each user.
