Patent ID: 10802714

Abstract:
A method for optimizing access to files in Universal Integrated Circuit Card (UICC) for use in User Equipment (UE) is provided. The method includes transmitting, by UE, to UICC, SELECT command to select master file (MF); receiving, by UE, from UICC, file control parameter (FCP) values of MF; transmitting, by UE, to UICC, SELECT command to select elementary file directory (EF-DIR) based on FCP values of MF; receiving, by UE, from UICC, FCP values of EF-DIR; determining, by UE, application available in UICC listed in EF-DIR based on FCP values of EF-DIR; transmitting, by UE, to UICC, SELECT command to select application directory file (ADF); receiving, by UE, from UICC, FCP values of ADF; reading, by UE, an elementary file control parameter (EF_FCP) file by using a short file identifier (SFI) value included in the FCP values of the ADF; and obtaining, by the UE, contents of the EF_FCP file.
