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
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
Heidelberg, 25 February 1999
MTM’99 Workshop
Use of IC cards
Physical and functional interface between the terminal and the IC card
Mechanisms to download information into the terminal Security for downloadable data and applications Standardized execution environment for downloadable services (e.g. MExE, SIM Application Toolkit)
Heidelberg, 25 February 1999
MTM’99 Workshop
Applications
Identification of the terminal capabilities Support of the VHE while roaming External standardized functional interface (e.g. API) Availability of specific applications Capability to interface with specific devices Mechanisms to encode/decode video/audio streams Synchronization of media streams Standardized API to interact with the terminal (e.g.
SIM Application Toolkit)

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

SIM Application Toolkit
It permits to exploit the computational power and the memory of SIM cards
SIM cards can start actions that will be executed by the terminal (sending of SMs, call control,
menu management, access to local information, etc.) Download over the air of data and applications (e.g.
via SMS) Example of client-server application based on the
