Abstract (EN): The current heterogeneous world of networks and terminals combined with the generalized mobility of users pose telecommunications operators and service providers the challenge of dynamically adapt the services they provide. This paper presents a proposal to solve the problem of the adaptation of multimedia services in mobile contexts. The paper combines context-awareness techniques with user interface modeling and description to dynamically adapt telecommunications services to user resources, in terms of terminal and network conditions. The solution is mainly characterized by the approach used for resolving the existing dependencies among user interface variables, which is based on the constraints theory, and by the mechanism for acquiring the user context information, which uses the Parlay/OSA interfaces. The experiments and tests carried out with these techniques demonstrate a general Improvement of the adaptation of multimedia services in mobile environments, in comparison to systems that do not dynamically integrate the user context information in the adaptation process. © 2008 Academy Publisher.
