  1. Terminal and Application Aspects of the Evolution of Broadband Mobile Services EURESCOM P809 Mobility in the Broadband Environment based on IN Evolution Giuseppe Plagenza Tel: +39 011 2286476 Fax: +39 011 2286190 E-mail: Giuseppe.Plagenza@cselt.it

  2. 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

  3. 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

  4. 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)

  5. 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)

  6. 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)

  7. Security Aspects Goals Confidentiality Integrity Availability Legitimacy Accountabilities Solutions Authentication Access priorities Ciphering Different policies Recovery from viruses

  8. Client-Server Framework

  9. HTMLBrowser WAP Server Web Server DBMS WAP Services WMLBrowser INTERNET INTRANET

  10. Server Application Gateway Client Application SMSC 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 SIM Application Toolkit: TCP/IP TCP/IP SMS
