An approach for modeling and simulation of user-perceived quality of services in hybrid (broadcast and telecommunication) networks is presented in this paper. The term "user-perceived quality of service" goes beyond the QoS concepts for packet based end-to-end communication. Rather, the service and the information transmitted by such a service will be modeled at a more abstracts, semantic level. General components of user-perceived QoS will be defined. However, the technical QoS parameters of different part of hybrid networks may contribute to this user-perceived QoS model as well as application specific characteristics, client terminal features or user profiles. A use-case driven modeling methodology is introduced which leads to simulation models applicable to simulation experiments for characterization and optimization of services in hybrid networks from a user's QoS perspective. As an example, user-perseived QoS of a data service in digital TV will be simulatad with OMNeT++.
