COMMON RADIO RESOURCE MANAGEMENT APPARATUS FOR HANDOVER BETWEEN HETEROGENEOUS NETWORK, LOCAL RADIO RESOURCE MANAGEMENT APPARATUS FOR HANDOVER BETWEEN HETEROGENEOUS NETWORK AND HANDOVER METHOD BY MANAGING COMMON RADIO RESOURCE MANAGEMENT OVER HETEROGENEOUS NETWORK ENVIRONMENT

摘要

PURPOSE: A common radio resource management apparatus for handover between heterogeneous networks, a local radio resource management apparatus for handover between heterogeneous networks, and a handover method by managing common radio resource management over a heterogeneous network environment are provided to efficiently supply the services of various service qualities to a mobile terminal by supporting the handover between heterogeneous networks through integrated wireless resource management. CONSTITUTION: A network state information management unit(110) receives network state information non-dependent on a network from heterogeneous networks. A mobile terminal information management unit(120) receives mobile terminal information non-dependent on the network from each network of heterogeneous networks. Based on the state information of the nondependent network and the information of the non-dependent mobile terminal, a network selection unit(130) selects the network for handover.
