Study on UICC/USIM enhancements
The present report identifies use cases and potential requirements for new USIM services with a focus on:
- Instances where the USIM is used inside terminals with specialised functionalities (e.g. radio modems, 3G Notebook terminals);
- Possible enhancements to facilitate USIM-UICC support for new services;
• Possible enhancements to facilitate an improved user experience when interacting with the UE; and
- Evolution from the USAT towards multimedia USIM toolkit support.
The present report covers only use cases and services that cannot be fully implemented and easily realised using the existing standards, but instead require some enhancement of the present UICC/USIM requirements. Alternative technical solutions (i.e. non USIM-based solutions) are also introduced and referenced for use cases in order to provide a more complete picture of how they might best be realised.
