With the advent of the third and fourth generation, mobile radio networks are entering a new phase of their evolution. These systems must allow mobile users to access their personalized services and their environment regardless of the network radio access technology and the used terminal type. Current solutions are not sensitive to the context and do not take into account parameters that change with the dynamic component constitution of the mobile environment. In this paper we are interested to the adaptation of services to networks with different radio access technologies while maintaining the requested quality of service and the mobile user context. Simulation results show that the effects of the use of context awareness in the decision of handover can quickly converge to a fixed optimal choice while guaranteeing the free movement of mobile hosts across different networks depending on the required QoS.
