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. Within the scope of the present document, the UICC refers here to an ICC which
supports at least one application in order to access a network. This application is called here Network Access
The ICC is considered as a platform, which is either based on TS 102 221
or TS 102 600
, here called
"3G platform", or 3GPP TS 51.011
, here called "2G platform".
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.
