How does our network look like ?
D2 Vodafone has more than 19 Million customers
Our customers generate more than
750 Million SMS/month
We operate an installed basis of > 100 MSCs and
20.000 radio cells
We frequently add MSCs, SMSCs, IN-Systems,
VoiceMail Systems, Voice Response Units........
We launch numerous services per year
We stick to multi-vendor capability
UMTS roll-out plans are in progress

Platforms have been added to create services
• Over the years we have added various platforms for service offerings
 Voicemail
 SMS Service Center
 Various Voice Response Units for service customisation, special information ....
 Pre-Paid Service Platforms
(IN, HotBilling, AoC)
 CellBroadcast Service Center
 WAP Gateway & Server
 Internet Services

Options are benefits and threats
What is the best choice for
service creation and deployment?
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

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?

Page 26
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
Armin Toepfer, MMO, 01/2001
25 - 26 January 2001, Bremen, Germany
Page 27
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?

de-central services concepts
OSA (Open Services Architecture) is created for

How we can provide sound and stable services
with mixed architectures?
Service modification management?

Service modification management?
Charging management?

Multimedia services
Standards 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]

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?
