  • METHOD FOR SWITCHING BETWEEN A FIRST AND A SECOND LOGICAL UICCS COMPRISED IN A SAME PHYSICAL UICC
    Publication number: 20140031083
    Abstract: A method for switching between first and second logical U ICCs in the same physical U ICC. Each logical UICC has an area for storing overlapped volatile data and an area for storing overlapped persistent data. The physical UICC also has an OS area. When a switch order is received to switch from the first logical UICC to the second logical U ICC. Overlapped volatile data from the OS area is backed up to the area for storing overlapped volatile data of the first logical U ICC. Overlapped persistent data from the OS area is backed up to the area for storing overlapped persistent data of the first logical U ICC. Volatile data from the area for storing overlapped volatile data from the second logical UICC is restored to the OS area. Persistent data from the area for storing overlapped persistent data from the second logical UICC is restored to the OS area.
