3. Heidelberg, 25 February 1999 MTM’99 Workshop Goals  To investigate terminal development in relation to the introduction of broadband mobile multimedia services  To review the communications and application technologies associated with these “new” terminals

4. Heidelberg, 25 February 1999 MTM’99 Workshop Terminal Requirements 1.The set of general-purpose requirements for UMTS terminals needs extending 2.The resulting set of requirements can be splitted into three classes of features: - Features related to the use of IC cards - Features related to applications - Features related to mobility

5. Heidelberg, 25 February 1999 MTM’99 Workshop Use of IC cards ò Physical and functional interface between the terminal and the IC card ò Mechanisms to download information into the terminal ò Security for downloadable data and applications ò Standardized execution environment for downloadable services (e.g. MExE, SIM Application Toolkit)

6. Heidelberg, 25 February 1999 MTM’99 Workshop Applications ò Identification of the terminal capabilities ò Support of the VHE while roaming ò External standardized functional interface (e.g. API) ò Availability of specific applications ò Capability to interface with specific devices ò Mechanisms to encode/decode video/audio streams ò Synchronization of media streams ò Standardized API to interact with the terminal (e.g. SIM Application Toolkit)

7. Heidelberg, 25 February 1999 MTM’99 Workshop Mobility Requirements ò Registration/deregistration to SP and NO ò Location update ò Connection oriented or connectionless services ò Unalterable equipment identification ò Emergency calls even without a USIM ò Authentication and encryption mechanisms ò Handover ò Different access modes (e.g. DECT, GSM-900, GSM- 1800, GPRS-900, GPRS-1800, UMTS FDD CDMA, UMTS TDD CDMA)

8. Heidelberg, 25 February 1999 MTM’99 Workshop Security Aspects Goals Confidentiality Integrity Availability Legitimacy Accountabilities Solutions Authentication Access priorities Ciphering Different policies Recovery from viruses

9. Heidelberg, 25 February 1999 MTM’99 Workshop Client-Server Framework

10. Heidelberg, 25 February 1999 MTM’99 Workshop HTML Browser WAP Server INTERNET INTRANET WML Browser Web Server DBMS WAP Services

11. Heidelberg, 25 February 1999 MTM’99 Workshop SIM Application Toolkit ò It permits to exploit the computational power and the memory of SIM cards ò SIM cards can start actions that will be executed by the terminal (sending of SMs, call control, menu management, access to local information, etc.) ò Download over the air of data and applications (e.g. via SMS) ò Example of client-server application based on the SIM Application Toolkit: SMS Server Application SMSC Gateway Client Application TCP/IP TCP/IP
