Abstract
With the advent of
the Internet and the plurality and variety of fancy applications it brought
with it, the demand for more advanced services on cellular phones is
increasingly becoming urgent. Unfortunately, so far the introduction of new
enabling technologies did not succeed in boosting new services. The adoption of
Internet services has shown to be more difficult due to the difference between
the Internet and the mobile telecommunication system. The goal of this paper is
to examine the characteristics of the mobile system and to clarify the
constraints that are imposed on existing mobile services. The paper will also investigate successively
the enabling technologies and the improvements they brought. Most importantly,
the paper will identify their limitations and capture the fundamental
requirements for future mobile service architectures namely openness,
separation of service logic and content, multi-domain services,
personalization, Personal Area Network (PAN)-based services and collaborative services. The paper also explains the analysis of current mobile service
architecture such as voice communication, supplementary services with
intelligent network, enabling services on SIM with SIM application tool kit,
text services with short message service, internet services with WAP and
dynamic applications on mobile phones
with J2ME.
