A Novel Joint Radio Resource Management with Radio Resource Reallocation in the Composite 3G Scenario

Zhe Ding and Yubin Xu    

Abstract: Joint Radio Resource Management (JRRM) is the envisaged approach to optimize the radio resource usage of the heterogeneous wireless networks. In particular, this study proposes a novel Joint Radio Resource Management framework with the Radio Resource Reallocation function to improve the radio resource efficiency. Radio Resource Reallocation entity is introduced to the JRRM framework which dynamically reallocates the ongoing sessions of different Radio Access Networks to achieve better radio resource utilization. In order to realize Radio Resource Reallocation, we build the system model of the composite 3G scenario and investigate the Radio Resource Reallocation approach based on Integer Programming. Simulation results demonstrate that the proposed JRRM with Radio Resource Reallocation function can improve the radio resource efficiency and perform better than that without Radio Resource Reallocation function.
