Patent ID: 8408474

Claim:
A Method for speeding up the detection and the activation of the communication protocol used between a terminal and a UICC (Universal-Mobile-Telecommunication-System Integrated Circuit Card) supporting at least one High Speed protocol (HSP), said method characterized by providing the terminal with information about the High Speed Protocol supported by said UICC through the current interface prior to the communication with said UICC through a HSP interface; wherein the detection of the HSP between the terminal and the UICC comprises: the terminal sends to the UICC a Reset signal through the ISO (International Organization for Standardization) interface, in response to said Reset Signal, the UICC sends to the terminal an ATR (Answer To Reset), including information about the HSP supported by the UICC, and the information about the HSP supported by said UICC is transmitted to the terminal within bytes of the ATR unused under ISO/IEC 7816.
