Abstract:
Services quality management represents on of the key
features of the wireless seamless telecommunications
data solutions dedicated for the Intelligent
Transportation Systems. Private solutions can frequently
guarantee reasonable service quality level, however,
their signal area coverage use to be significantly
limited and the economical parameters of private
solutions are much less desirable than the ones offered
by the public provides. Public providers usually offer
high service penetration in widely spread areas,
nevertheless, these providers typically do not guarantee
even lower level of the data services quality. Widely
spread mobile solutions with reasonable quality level
can be reached by the dynamical selection of the best
possible service from the set of just accessible
wireless services. Implementation is based on the
seamless switching/routing structures managed by results
of those adaptive decision processes. CEN TC204, WG16.1
team has been working on series of documents known as
CALM family of standards. CALM is based on L2 switching
and for decisions the Policy-based Management (PBM)
principles are applied. In contrary to CEN team approach
authors of this paper propose "alternative CALM"
solution based on the L3 routing managed by the decision
processes designed on principles of the adaptive
classifications. This solution belongs to category of
"intelligent routing". Related alternative solution can
be more efficiently implemented if there is available
deep enough understanding of the applied technologies.
Paper presents the first implementations experiences
based on the results of the laboratory studies of three
most widely spread data wireless services.
