The emerging and future radio landscape will consist of heterogeneous wireless networks, operating in the framework of diverse cooperative associations of network operators, for accommodation of the demands of users with multimode and/or multihoming enabled terminals. In this context, the optimized spectrum and radio resource utilization will be key factors for the accomplishment of the goals of both users and operators, namely the satisfaction of users' needs and the augmentation of operators' profi ts. The IEEE P1900.4 standardization group is working towards specifying architectures and functions that will enable network-terminal distributed decision making for optimized radio resource usage in such heterogeneous wireless access networks. In alignment with the recently standardized P1900.4 management architecture, in this paper we (a) propose a functional architecture for the management and optimization of spectrum and radio resource utilization in heterogeneous wireless environments, (b) give a thorough description of the information that needs to be conveyed on the external interfaces of the proposed architecture, and (c) set up an experimentation platform and conduct indicative scenarios for both the demonstration and performance assessment of the proposed architecture. The assessment results show satisfactory behavior in terms of induced management signaling loads and time delays, that is equivalent to minimal intervention into the real network operation.
