This paper presents the architecture and functional model of cooperative radio resource management (Co-RRM) for the efficient integration of different radio access technologies. The cooperative management mechanism and procedure is designed and the policy-based network resource allocation algorithm is introduced to keep mobile users always best connected. In order to optimize the resource utilization, a scheme namely adaptive vertical handover (AVHO) based on the information of available bandwidth passed from Layer 2.5 trigger is proposed. We have implemented the cooperative management scheme on the simulation platform, and investigated the improvement of transmission control protocol (TCP) performance during vertical handover, and demonstrated the enhancement of resource utilization under the control of Co-RRM.
