Mobile Service - Definition
• “A radiocommunication service between mobile and land
stations, or between mobile stations.” – traditional, short
• “Radiocommunications services between ships, aircraft,
road vehicles, or hand-held terminal stations for use while
in motion or between such stations and fixed points on
land.” – official, by WTO
• “Any service that can be operated on a mobile device,
such as both voice and data services, for example,
roaming, SMS and MMS, video streaming, location-based
services, etc.” – technically oriented

Mobile Services vs. Web
Services
• Many Web Services and APIs were originally developed
with server to server or server to browser in mind, not
mobile applications
• Mobile platforms have their own set of challenges given:
–
–
–
–
–
–
Bandwidth
Memory and CPU Availability
Storage Capacity
Connectivity Options and Issues
Security
User Interaction and Display

Web Service
Making Mobile Services
Widespread
Mobile services have not (yet) reached the success of Web
• If mobile services are to repeat the success of the Web they
have to be:
• simple to use,
• simple to find,
• simple to trust,
• simple to create/set up.
• These are the design goals of numerous projects, such as
“SMS: Simple Mobile Services”, OPUCE, m:Ciudad.

IMS Concept
What is IMS?
• IP Multimedia Subsystem (IMS) is a Service Delivery
Architecture
• Standardized architecture to provide Internet
Protocol (IP)-based mobile and fixed multimedia
services
• IMS architecture has evolved over the past few years
• Today, IMS could allow operators who own different
types of networks with varying architectures to offer
the same services to all of their customers

RFID Technology –
Introduction
• Radio Frequency Identification - means to
efficiently and quickly auto-identify
objects, people, etc.
• Real-time tracking of inventory in the
supply chain
• RFID tag – tiny computer chip with very
small antenna – passive/active
• The chip contain Electronic product code
(EPC) – uniquely identify the object
• The antenna transmits EPC to RFID
reader – within a certain RF range,
without requiring line-of-site
www.sti-innsbruck.at
16
RFID Technology - Properties
• Advantages:
–
–
–
–
–
rough conditions,
long read ranges,
portable databases,
multiple tag read/write,
tracking items in real-time
• Results:
–
–
–
–
–
quick scanning of products in large bulks,
automated supply chain management
significant savings
accuracy of shipment sent and received,
check on product theft, counterfeiting, product recall, ...
www.sti-innsbruck.at
17
Mobile RFID technology
• Vision of automatic identification and ubiquitous
computing – „Internet of things“
– highly connected network
– dispersed devices, objects, items can communicate
each other
– real-time information about objects, location,
contents, destination, ambient conditions
– efficient and easy M2M identification, communication
and decision-making
• Handheld portable devices – mobile phones, PDAs –
behaves as RFID readers and tags
– conventional RFID closer to common user

End-User Empowerment in
Converging Service Platforms (1)
• Redefining the role of Telco: from access to service provider
– Enabling new business models (e.g. «prosumers» vs.
consumers)
• Inter-domain aspects: service provisioning, inter-working
Integration with the (Semantic)
Web is inevitable for having a
common large information pool
• Make services intelligent and easier to use (assist users)
Semantically enabled
smart user interfaces

25
End-User Empowerment in
Converging Service Platforms (2)
• Hiding complexity and heterogeneity
– Taking benefit of existing variety of services, networks and
devices
• Opening platform capabilities to 3rd parties
• Support multi-vendor, multi-technology middleware platforms
Ontology technology is built to handle
heterogeneity and variety
• Provide services timely:
accelerate creation &
delivery of services
– Fast service creation
– Reduce time-to-market
for new services

Creation, discovery,
composition of enablers and
services is accelerated on the
basis of shared ontologies &

Example for Policies
www.sti-innsbruck.at
33
Motivation: Why Edit Policies?
End User Perspective
• Personal data and identity managment
– „Who is watching me?“, e.g., choose to whom you
want to reveal your location and presence and to
whom not
• Policy awareness, acceptance/rejection
– „What is going on?“, „Why?“, e.g., learn about
government, finance, legal, business procedures
Organizational Perspective
• Policy management
– „Define, set, communicate, share policies“, e.g.,
conditions of selling a service at a WWW
marketplace

m:Ciudad - Vision
• m:Ciudad, a step forward in Mobile User-generated Content
and Services. A service infrastructure for the mobile platform for:




Instantaneous, on-the-go service creation and
provision. The mobile user as a prosumer:
producer, provider and consumer of services
and their associated contents.
Fixed-mobile service convergence in a wide
sense: one worldwide user-powered content
network.
Efficient context utilization. Automatic /
manual context-aware content generation and
publication.
Discovery, access and mobile-to-mobile
communication in a very distributed, volatile
platform (such as the mobile one, with the
service “not-always-on” paradigm).

Conclusions
Thank you for the attention.
Starbucks comes from America (and there are several ones in
Vienna!).
Many would agree that coffee is better
in Austria than in the US.
Why wait till somebody else empowers
end-users with semantic mobile services in the converging
world?
