Autobiography
Andrej Štern is a post-graduate student
at the Faculty of, Ljubljana Universiy, where he graduated
from telecommunications in 1999 and in 2003 received
his Master's degree. He is employed in the Laboratory
for Telecommunications at the Faculty of Electrical Engineering,
where he is researching a development of mobile communications
with the emphasis on technologies, services and contents
of the future. His spheres of interest also comprise
a development of applications, electronic systems and
Internet usage. Within his pedagogical activities, he
is passing on his knowledge and experiences to younger
generations and appears as the author of several articles.
Matej Eljon graduated in 1999 at the Faculty of Electrical
Engineering in Ljubljana and in 2003 received his Master's
degree. He had joined the Laboratory for Telecommunications
early in his studying and begun to participate actively
at research and project work. His pedagogical, research
and developmental work is connected with planning and realising
telecommunication services, computer telephony applications
and interactive video services within e-learning. His other
spheres of interest are mobile communications and bandwidth
networks. He is the author of several articles related
to the mentioned research areas.
Subject
Convergence of Service
and Universal Communication
Today, twelve years after introducing the first analogue
system of cellular telephony in Slovenia, telecommunications
are present everywhere. The presence of mobile phones,
palms and portable computers with telecommunication expansions
had exceeded all the limits. Many people can't imagine
a life without all these electronic devices anymore.
With packaged upgrade of circle streamed commutated cellular
networks, the mobile terminal with its WAP services acquired
the mentioned internet contents and services, which are
becoming multimedial with their new varieties. These
image, sound and data contents demand slightly bigger
bandwidth, which Slovenia will be able to attain with
the third generation network UMTS not until the end of
the year. Transmitting speeds up to 384 kbit/s are usually
enough for the video transmission of low dissolution,
but for a bit less mobile and much faster browsing the
wireless network LAN is being established in the coverage
areas set in the city centres, shopping centres, airports
and some educational institutions.
Technology behind the users terminals and on the side
of the service provider is of no interest to public.
They are encountering sound, data and communicational
services when using modern mobile services. In many cases
these services are becoming mixed with others, until
recently separated areas and this way they are creating
convergent services.
First of the mobile services to be introduced combines
speech transmission with information supported systems
of speech services. Technologies, meant for developers
as well as services, which are the product of cooperation
between several providers, will be mentioned. The next
topic will present data services, with the emphasis on
expansion of the WAP protocol usage, WAP being the basic
network for Java applications. The possibilities of adjusting
contents to many different data clients will also be
discussed. Further, we will present communication services
that became interesting above all with the appearance
of message capturing framework and their mediation to
external service providers' web servers.
As the typical example of convergence, we will mention
the cooperation of television house, mobile operator
and Laboratory for Telecommunications of the Faculty
of Electric Engineering in Ljubljana.
Special complex of combining different technologies
and services can also mean universal messaging. This
is actually about capturing various contents and presenting
them through different speech and data channels. When
discussing universal messaging we will present the needed
technologies and implementation of some services that
will in the future enable to read or send e-mails through
speech interface in Slovenia as well. |
