"The present document defines the interface between the R-UIM and the Mobile Equipment (ME)@ and mandatory ME procedures@ specifically for CDMA Card Application Toolkit (CCAT). As stated in [1]@ the UICC refers to an ICC that supports a Network Access Application. All references to UICC in [1] shall be interpreted as a card holding a network access application@ e.g. an R-UIM@ in this document. In the present document@ the term R-UIM is used in a generic way to specifically refer to an ICC holding a CDMA network access application. The present document refers in its majority to which describes the generic aspects of application toolkits within the UICC. CCAT is a set of commands and procedures for use during the network operation phase of CDMA@ in addition to those defined in [13]. Specifying the interface is needed to ensure interoperability between an R-UIM and an ME independently of the respective manufacturers and operators. The present document defines for CDMA technology: - The commands; - The application protocol; - The mandatory requirements on the R-UIM and ME for each procedure. CCAT will allow Service Providers to offer unique services to their subscribers by placing applications they have designed (or third party applications) on the R-UIM that would function on any particular manufacturer's ME that supports the Toolkit features. These requirements are expressed as additions to current release of [1]. The composite CCAT specification is comprised of [1] and this ancillary document. The present document does not specify any aspects related to the administrative management phase. Any internal technical realizations of either the R-UIM or the ME are only specified where these reflect over the interface. The present document does not specify any of the security algorithms@ which may be used. Within the context of the present document@ the term ""terminal"" used in [1] refers to the Mobile Equipment (ME). Within the context of the present document@ the term ""NAA"" used in [1] refers to the CDMA Card Application Toolkit (CCAT)."
