Abstract :
In face of heterogeneous RATs coexisting in next generation communication system, the network selection is related to Cooperative Radio Resource Management (CRRM) and QoS requirements of traffics and users´ preference etc to give the best choice for the users. Based on the proposed MAC layer architecture which set Cooperative RRM manager, in this paper the Differentiated Traffics Relative Band Request (RBR) - based algorithm-DTRA is proposed, which is not only a low complexity, centralized network selection scheme aiming to optimally distribute the end users to the networks of the heterogeneous wireless system in the sense of maximizing the global spectrum efficiency, but also considers the priorities of various traffics to decrease the loss rate of real-time traffics.
