Abstract

Disclosed is a hybrid terminal, which includes a mobile terminal unit for a Global System for Mobile communication (GSM) or a General Packet Radio Service (GPRS), a PDA (Personal Digital Assistant) unit combined with the mobile terminal unit, and a mirror database being connected between the mobile terminal and the PDA, for providing a memory space required for operations of the mobile terminal and the PDA, wherein the PDA includes a database for storing PDA data, reads the PDA data, and stores the read PDA data in the mirror database, wherein the mobile terminal includes a Subscriber Identity Module (SIM) card for storing SIM data, reads the SIM data, and stores the read SIM data in the mirror database.

Claims

1. A hybrid terminal comprising:

a mobile terminal unit for a Global System for Mobile communication (GSM) or a General Packet Radio Service (GPRS);

a PDA (Personal Digital Assistant) unit combined with the mobile terminal unit; and

a mirror database being connected between the mobile terminal and the PDA, for providing a memory space required for operations of the mobile terminal and the PDA,

wherein the PDA includes a database for storing PDA data, reads the PDA data, and stores the read PDA data in the mirror database, and

wherein the mobile terminal unit includes a Subscriber Identity Module (SIM) card for storing SIM data, reads the SIM data, and stores the read SIM data in the mirror database.

2. The hybrid terminal in claim 1, wherein, when a new PDA record to be stored in the database for storing PDA data is generated, the PDA stores the new PDA record in the mirror database and the database for storing PDA data.

3. The hybrid terminal in claim 1, wherein, when a PDA record to be deleted from the database is generated, the PDA deletes a corresponding PDA record stored in the mirror database and the database for storing PDA data.

4. The hybrid terminal in claim 1, wherein, when a new SIM record to be stored in the SIM card is generated, the mobile terminal stores the new SIM record in the mirror database and in the SIM card.

5. The hybrid terminal in claim 1, wherein, when a new SIM record to be deleted from the SIM card is generated, the mobile terminal deletes a corresponding SIM record stored in the mirror database and in the SIM card.

6. The hybrid terminal in claim 1, wherein the data stored in the mirror database includes a copy protection attribute and a hidden attribute.

7. A method for managing a database in a hybrid terminal in which a mobile terminal for Global System for Mobile communication (GSM) or a General Packet Radio Service (GPRS) is combined with a PDA (Personal Digital Assistant), the mobile terminal including a Subscriber Identity Module (SIM) card for storing SIM data, the PDA including a database for storing PDA data, the method comprising the steps of:

generating a mirror database for providing a memory space required for operations of the mobile terminal and the PDA after being connected between the mobile terminal and the PDA;

reading the PDA data and storing the read PDA data in the mirror database; and

reading the SIM data and storing the read SIM data in the mirror database.

8. The method in claim 7, further comprising the step of, when a new PDA record to be stored in the database is generated, storing the new PDA record in the mirror database and the database for storing PDA data.

9. The hybrid terminal in claim 7, further comprising the step of deleting a corresponding PDA record stored in both the mirror database and in the database for storing PDA data, when a PDA record to be deleted from the database is generated.

10. The hybrid terminal in claim 7, further comprising the step of storing the new SIM record in both the mirror database and in the SIM card, when a new SIM record to be stored in the SIM card is generated.

11. The hybrid terminal in claim 7, further comprising the step of deleting a corresponding SIM record stored in the mirror database and in the SIM card, when a new SIM record to be deleted from the SIM card is generated.

12. The hybrid terminal in claim 7, wherein the data stored in the mirror database includes a copy protection attribute and a hidden attribute.
