The present document defines the interface between the UICC and the terminal, and mandatory terminal procedures,
specifically for "NAA Card Application Toolkit".
The Card Application Toolkit (CAT) is a set of generic commands and procedures for use by the ICC, irrespective of
the access technology of the network.
NAA can be:
a USIM application, as defined in 3GPP TS 31.102, which can reside only on a 3G platform;
a SIM application, as defined in 3GPP TS 51.011, which can reside either on a 3G or a 2G platform;
a TSIM application, as defined in TS 100 812, which can reside only on a 3G platform;
a ISIM application, as defined in 3GPP TS 31.103, which can reside only on a 3G platform;
a RUIM application, as defined in TIA/IS-820-A, 3GPP2 C.S0023-0, which can reside on a
2G platform; or
other applications residing on a 3G platform or a 2G platform. Specifying the interface is to ensure
interoperability between an ICC and a terminal independently of the respective manufacturers and operators.
The present document specifies as well mechanisms in order to expand the generic set of commands and procedures by
access technology specific ones.
