This TS contains the core requirements for a USIM application Toolkit (USAT) which are sufficient to provide a complete service.
The scope of this TS encompasses the USAT functionality in the UE (comprising USIM and ME) and the interaction with the PLMN environment. The USAT Server is not necessarily a separate entity; nodes providing USAT services may also exist within the PLMN. The functionalities of the USAT servers (such as charging aspects, security level classification etc.) are not covered by this TS.
