In this paper, a access architecture for joint radio resource management (JRRM), hierarchical architecture, is given after analyzing advantage and disadvantage of the existing architectures, which is consider as one of architectures the future heterogeneous radio networks most possibly uses .Then a novel scheme is proposed based on this hierarchical architecture and the work flow of it is discussed in detail. The innovation of this scheme is that dynamic spectrum management (DSM) is integrated into the existing JRRM schemes based on predicting traffic in every radio access technologypsilas(RAT) cells. In order to evaluate performance, a new concept, spectrum utility, is used which reflects degree and efficiency of resources utilization. Compared with the JRRM without DSM, this scheme can improve spectrum utility and reduce blocking rate.
