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.
