First Claim
Patent Images
1. A method of subscriber identity module/universal subscriber identity module (SIM/USIM) personalizing a user equipment, comprising:
- acquiring an integrated circuit card identity (ICCID) of a specific smartcard;
storing the ICCID of the specific smartcard in the user equipment as feature data;
accessing an integrated circuit card identity elementary file (EFICCID) of a currently inserted smartcard of the user equipment during a booting process; and
the user equipment entering a normal mode when determining that the integrated circuit card identity elementary file matches the feature data.

Abstract
When SIM/USIM personalizing a user equipment, a unique ICCID, which is not protected by PIN, of a specific smartcard is used as feature data. Even in a PIN-locked status, the user equipment may directly access an integrated circuit card identity elementary file of a currently inserted smartcard and then determine whether the currently inserted smartcard is the specific smartcard without waiting for the PIN-unlock process to complete. Therefore, the present method of performing SIM/USIM personalization does not influence the efficiency of the booting process.
