Oriented to heterogeneity in every sense, next generation wireless networks are aimed to fulfil constantly increasing users' prospects. Relying on the all-IP paradigm, expectations suppose ubiquitous wireless access in heterogeneous networks. When efforts are made to make such an aspiration a reality, the main challenging issue raised is the need to seamlessly provide the user with an adequate Quality of Service (QoS) level. This paper gives detailed description of end-to-edge QoS approach in a heterogeneous wireless access network adopted in AROMA project and addresses the most important issues and observations that occurred during the implementation of such a solution in a real-time testbed. The paper gives some qualitative results on possibilities to implement coordinated interdomain QoS management by QoS mechanisms independently developed for radio and core network domains. Additionally, it gives an insight into real-time possibilities to track QoS provision across multiple domains revealing real-time behaviour before, during and after the system reconfiguration.
