Abstract

A method for accessing an SIM in a composite terminal. The method includes determining, by a Personal Digital Assistant (PDA) module, whether a subscriber identification information request signal occurs; and directly accessing the SIM and reading the subscriber identification information stored in the SIM when the subscriber identification information request signal occurs.

Claims

1. A method for accessing a Subscriber Identification Module (SIM) in a composite terminal comprising:

determining, by a Personal Digital Assistant (PDA) module, whether a subscriber identification information request signal occurs; and

directly accessing the SIM and reading the subscriber identification information stored in the SIM when the subscriber identification information request signal occurs.

2. The method as claimed in claim 1, further comprising:

determining, by the PDA module, whether a user data request signal occurs; and

directly accessing the SIM and reading user data stored in the SIM when the user data request signal occurs.

3. The method as claimed in claim 2, wherein the user data includes a phone book and Short Message Service (SMS) data.

4. A composite terminal comprising:

a Subscriber Identification Module (SIM) for storing information of a subscriber and user data;

a Personal Digital Assistant (PDA) module for directly accessing the SIM and reading the information and the data stored in the SIM; and

an interface for directly connecting the SIM to the PDA module.

5. A method for accessing a Subscriber Identification Module (SIM) in a composite terminal, the method comprising:

determining, by a phone module, whether it is possible to access the SIM when the composite terminal is powered on;

transferring information regarding whether it is possible to access the SIM to a Personal Digital Assistant (PDA) module;

determining, by the PDA module, whether it is possible to access the SIM through the received information; and

directly accessing the SIM and reading information stored in the SIM when it is possible to access the SIM.

6. The method as claimed in claim 5, wherein the information stored in the SIM includes secret identification data, subscriber identification information containing a cell phone number of a subscriber, and user data containing a phone book and Short Message Service (SMS) data.

7. The method as claimed in claim 6, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been detached from, or mounted on, the composite terminal.

8. The method as claimed in claim 6, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been locked.

9. The method as claimed in claims 6, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has an abnormal condition.

10. The method as claimed in claim 5, wherein the SIM is respectively connected to the phone module and the PDA module by hardware.

11. The method as claimed in claim 10, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been detached from, or mounted on, the composite terminal.

12. The method as claimed in claim 10, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been locked.

13. The method as claimed in claims 10, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has an abnormal condition.

14. The method as claimed in claim 5, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been detached from, or mounted on, the composite terminal.

15. The method as claimed in claim 5, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has been locked.

16. The method as claimed in claims 5, wherein the phone module determines whether it is possible to access the SIM according to whether the SIM has an abnormal condition.
