  • Optimizing access to universal integrated circuit card (UICC) files in a user equipment (UE)
    Patent number: 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.

  • OPTIMIZING ACCESS TO UNIVERSAL INTEGRATED CIRCUIT CARD (UICC) FILES IN A USER EQUIPMENT (UE)
    Publication number: 20180307415
    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.

  • Optimizing access to universal integrated circuit card (UICC) files in a user equipment (UE)
    Patent number: 10013164
    Abstract: A method and a User Equipment (UE) are provided for optimizing access to Universal Integrated Circuit Card (UICC) files in the UE. The method includes storing, by the UE, at least one File Control Parameter (FCP) file corresponding to a plurality of Elementary Files (EFs); and sending, by the UE, a command directly to the UICC, based on the at least one FCP file. The command includes one of a READ command and an UPDATE command.
