What is the best choice for

network vs. terminal centric concepts

What is the best choice

for the target backbone network?

circuit switched, packet or mixed

do we gain in terms of quality or do we loose

Is there really a gain for packet traffic with service mix ?


Options are benefits and threatsOptions 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?


Questions Questions & how they are addressed& how they are addressed

Old days are long gonewe never had an explicit research unit likeForschungsinstitut der Telekom

However, we do some own researchWe are happy to conduct a couple of joint studies -national and internationalThere are more questions we can address ourselves


Key Questions:Key Questions:Service creation conceptsService creation concepts

OSA (Open Services Architecture) is created forsystem and vendor independent service design Will OSA fly?What are the pre-requisites for afirm and sound specification of OSA?What else is necessary?What’s about Parlay?Do we get rid ofvendor’s services creation environment?


Integration of central andIntegration of central andde-central services conceptsde-central services concepts

OSA (Open Services Architecture) is created forsystem and vendor independent service design

Java terminals

How we can provide sound and stable serviceswith mixed architectures?

Service modification management?


Security architecture in an open Security architecture in an open service creation & provision service creation & provision environmentenvironment

Services will be created ,provided & operated bythe telecommunication operator,Application Service ProviderInternet Service Provider

How we can provide sound and stable serviceswith mixed service creation, operation and ownership?Service modification management?Charging management?


Multimedia servicesMultimedia servicesStandards for multimedia standards:

MPEG4, H.263+ (Video), mp3, AAC, (Audio), SMIL*,MPEG4-BIFS (Synchronisation - Presentation), ... + 3GPP 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]


Quality of Service (QoS)Quality of Service (QoS)Questions Questions Support of 4 Traffic Classes

ConversationalStreamingInteractiveBackground

QoS Negotiation and Re-negotiationQoS Mechanisms (to be supported across networks)

Label Switching (MPLS) and/orRSVP

Do such concepts hold what they promise?Are they applicable in large networks?QoS via multiple media gateways?
