The concept of the Virtual Home Environment (VHE) was introduced in mobile networks focusing on the issues surrounding the support of non-standard services for roaming users. This paper presents a proposal to solve the problem of the dynamic adaptation of multimedia services provided by a telecommunications operator in the context of the VHE concept. The paper discusses how the development of multimedia services can be facilitated in this context, how these services can be provided in a heterogeneous world of networks and terminals and how they can be used in a personalized and adaptable way. The paper defines a solution for the adaptation of multimedia services based on the real-time generation of user interfaces conditioned by the user context. 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.
