26 Page 26Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Options are benefits and threats  What are the mechanism for QoS across  several networks?  How we ensure reliability and ability to operate?  How we protect our network from threats?  How we ensure the integrity of services?  How we cater for billing all the services,  in particular for the pre-paid market?

27 Page 27Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Questions & how they are addressed  Old days are long gone  we never had an explicit research unit like  Forschungsinstitut der Telekom  However, we do some own research  We are happy to conduct a couple of joint studies -  national and international  There are more questions we can address ourselves

28 Page 28Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Key Questions: Service creation concepts  OSA (Open Services Architecture) is created for  system and vendor independent service design  Will OSA fly?  What are the pre-requisites for a  firm and sound specification of OSA?  What else is necessary?  What’s about Parlay?  Do we get rid of  vendor’s services creation environment?

29 Page 29Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Integration of central and de-central services concepts  OSA (Open Services Architecture) is created for  system and vendor independent service design  Java terminals  How we can provide sound and stable services  with mixed architectures?  Service modification management?

31 Page 31Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Multimedia services  Standards for multimedia standards: MPEG4, H.263+ (Video), mp3, AAC, (Audio), SMIL*, MPEG4-BIFS (Synchronisation - Presentation), GPP Audio codecs AMR Wideband AMR Quality of Service for multimedia services and applications in the GSM/3G depends on content and careful selection of client - server protocols (e.g. automatic adaptation on the link quality)  Best codecs for services?  Interoperation and link adaptation management? *Synchronised Integration Language [mix many media types like video, graphics, audio, text and vector based animation together andsynchronize them to a timeline]

32 Page 32Armin Toepfer, MMO, 01/ January 2001, Bremen, Germany Quality of Service (QoS) Questions  Support of 4 Traffic Classes  Conversational  Streaming  Interactive  Background  QoS Negotiation and Re-negotiation  QoS Mechanisms (to be supported across networks)  Label Switching (MPLS) and/or  RSVP  Do such concepts hold what they promise?  Are they applicable in large networks?  QoS via multiple media gateways?
