Accenture Mobile Web Watch 2010 – the user demand for 4G services
Markus Beckmann, Accenture, Germany

• Why some subscribers are using mobile services? And why others are not (yet) using them.
• When and where and over which devices are services used today?
• Implications for the market, i.e. what is required to push mobile services further.

LTE Potentialities and Challenges
Matthias Sauder, Vodafone, Germany

• Driving fixed and mobile convergence to cope with the customer needs
• Simplifying the network architecture Introduction of LTE as a new technologie while reducing complexity and cost
• Mastering the backhauling challenge
• Maintaining our best in class network quality during network transformation projects

Messaging in LTE
Dr. Günther Pospischil, mobilkom Austria, Austria

It is widely known that LTE does not provide native support for "legacy services" like circuit switched calls and short message service (SMS). Therefore it is necessary to specify interworking/fallback mechanisms. For voice there is already a lot of attention on options like circuit switched fallback, VOLGA or VoLTE. SMS messaging was addressed later in standardization, therefore several details are still open. Also other messaging possibilities (MMS, Instant Messaging) require further attention. This talk will address the following topics:

• SMS support in LTE - Is transport of "SMS PDUs" via SIP the only option? What are the pros&cons of various approaches?
• Domain selection for SMS (SIP over LTE vs. circuit switched delivery) and interworking aspects.
• Backwards compatibility issues of advanced LTE messaging (RCS, Instant Messaging, eMail, MMS).

Challenges of LTE and EPC Introduction
Dr. Thomas Schwabe, Telefónica o2 Germany, Germany

• LTE - just a new access technology offering a higher bandwidth?
• providing mobile services with an IP based access only
• the end device challenge
• LTE/EPC - an driver for fixed mobile convergence?

VoIP Market Developments from an US Perspective
HP Baumeister, Fraunhofer Digital Media Technologies, USA

In some respect, the US market has some unique conditions, in another, VoIP services are a global phenomena.
Mr. Baumeister will provide an overview of the most relevant US VoIP deployments such as “operator-provided services” (cable-VoIP, Verizon FiOS VoIP, etc.) as well as the various over-the-top (OTT) services such as Apple iChat and FaceTime, GoogleVoice, or the Verizon Wireless/Skype collaboration.

Remaining Challenges with LTE/EPS
Franz Seiser, Deutsche Telekom AG, Germany

• EPS as always-on system vs. IPv4 address exhaustion
• mobility between LTE and legacy
• the smartphone challenge
• EPS roaming and even more challenging: IMS roaming

LTE/EPC Rollout Challenges
Peter Zbären, Swisscom, Switzerland

Once the LTE access and EPC is introduced, the real challenge for an operator will begin.
What kind of products shall be offered beside of Mobile Broadband?
What about Voice-over-LTE?
How to integrate wireline VoIP and wireless VoIP in order to build FMC products?
How to integrate the new LTE technology with already existing legacy domains like Mobile-Softswitch?
What are the steps towards an IMS based target architecture?

Workshop - Session 3, October 15, 2010, 11:45 - 12:30

Intended Questions for Panel Discussion “Standards, Products, and Business Cases for Future Seamless Communication”
Moderator: Prof. Dr. Thomas Magedanz, TU Berlin/Fraunhofer FOKUS, Germany

The main idea of this panel is to discuss where LTE and the EPC technologies stand today and what opportunities the new technology brings and what challenges have to be still mastered:

1. 1. What is the LTE business case?
      Just lower Opex and Capex for "wireless DSL", or Smart Bitpipe (Qos for Apps)?
   2.  Is LTE just Wirelss DSL in rural areas (white Spot coverage)?
2. 1. When will we see LTE in bigger cities? For what?
   2. When will we see what LTE end systems (Samsung Dongle and what´s next)?
3. 1. When will we see Voice over LTE, i.e. CSFB and IMS-based VoLTE?
   2. What will be the relationship between VoLTE and IMS-based RCS?
   3. How important are open APIs over VoLTE and RCS?
   4. Will Skype and Google Voice be faster in the market as real OTT offer?
4. 1. Is LTE/EPC ready for international Roaming? What is missing?
   2. When will we see harmonized mobile and fixed NGN? Is 3GPP taking care for harmonization?
5. 1. Researchers talk about the Future Internet, i.e. post IP. What will be the impacts on the IP-based EPC evolution?
   2. Is LTE/EPC ready for the M2M service market?
6. Thesis: LTE will be toxic for operators, the available bandwidth will pave the road for Google and Co! Will network neutrality finally ruin any LTE/EPC business case?

Mobile Broadband Services - First RCS Experiences from Japan
Bertrand Souville, DOCOMO Communication Laboratories Europe GmbH, Germany

What is necessary to provide our customers with new values in communication services? “Telecom and Web convergence” will be the one promising way to provide it. This talk will address

1. Key technologies to realize it and
2. Examples of “Telecom and Web convergence” services.

M2M Opportunities - Lessons Learned from the US Market
Ronald M. Jubainville, Sprint, UK

The M2M market is predicted to be the next high growth market for the wireless market.  Sprint was one of the leaders in the M2M market with a number of new devices in the market for over four years and now expanding this lead with the first 4G network in the US that was launched now 2 years ago.  The M2M market has presented new challenges with a proliferation of devices and the customer’s expectations for Global connectivity are very different to your standard mobile user.  What can we do different in 4G to address the issues?

Mobile Broadband Bitpipes for OTT Services
Boaz Zilberman, fring, Israel

Having Internet connectivity on the go, powerful mobile devices and ease of application development – we can now reinvent the world in terms of remote automation, wireless control, M2M interactions and information access.
The limiting factors in making all of it blossom faster and more aggressively is the relative high costs of broadband connectivity, especially in roaming situations.
Although broadband services are fast to become a standard capability provided by our mobile carrier, side by side with voice and messaging, the pricing structure of it is not efficient enough to enable true M2M connectivity. OTT services introduced gradually into the market by small niche players, will accelerate the provisioning of seamless broadband access by network operators.

Opportunities for Wholesale and Enterprise Operators
Sebastian Krems, LambdaNet AG, Germany

Since the liberalization of the telecommunication industry we have seen much hype and buzz words. Only a few innovations became blockbusters. Significant price decline pushed many into betting on future revenues on fancy new services. Today we hear new promises from FTTH, LTE and apps to the communication requirements of smart grids.  How can we manage sustainability and what are the opportunities for infrastructure based wholesale and enterprise operators in the new ICT eco system? 

Are head-units in cars not just iPhones of a different kind, waiting to be filled with apps, be those coming from vehicle manufacturers or others? And is not LTE the platform we have been waiting for to provide acceptable bandwidth for downloading and operating these apps in a fast-moving vehicle? Well, probably yes and yes - but how utterly boring and unimaginative! The true power of broadband vehicle connectivity is not to replicate what already exists and is served well with existing devices: one can easily connect an iPhone to the vehicle screen and input controller – and if the phone is intelligent enough to detect its usage in a vehicle environment and reformats everything for safe usage while driving, why bother with creating yet another eco-system just for in-vehicle infotainment?

We have to look beyond such obvious scenarios and analyze what new and previously unattain-able features can be provided with LTE in vehicles - and how they might change the capabilities of the vehicle. Here is one thought along this line: Today's vehicles have a multitude of environ-ment sensors, among them radar and cameras. With sufficient bandwidth at its disposal, one ve-hicle might complement its own sensors with the sensors of another vehicle, resulting in a more comprehensive view of the outside world, in turn resulting in higher ability for adequate driver assistance, if not autonomous driving.

By tying more of these vehicles and sensors together, we get something like Google StreetView, only in real time – and not just with pictures, but with any other data the vehicle collects: tem-perature, rain, fog, traffic, etc. Collecting, aggregating, and distributing this data can be of use inside and outside the vehicle: if you travel 20% faster on a given stretch of road than 80% of all other drivers, that probably tells you something. But – fortunately for everyone in research – such applications show problems in abundance: a mind-boggling volume of data, questions of reliabil-ity and liability, and privacy issues beyond belief. Yet, once solved, the reward will be a whole new experience in driving – or being driven. And those who find these issues too complex can always go and build their vehicle app store...

Monetizing Mobile Connectivity in the Collaborative Economy
Philipp Freudenberger, SAP, Germany

Mobility is a core element of the evolution towards the hyperconnected world. As product companies adopt service-based business models, collaboration becomes increasingly real-time, and requires more sophisticated monetization models. What's IT's contribution to this?
