In radio access network (RAN) 1 of the present invention, the configuration of radio network controller (RNC) 4 is physically separated into control plane controllers (CPE) 41a - 41b for controlling signalling and user plane controllers (UPE) 42a - 42c for controlling user data. User plane controllers 42a - 42c report their own status information (traffic information/used channel bandwidth information/alarm information) to control plane controllers to which they belong, and control plane controllers 41a - 41b manage the status information of the user plane controllers for each of user plane controllers subordinate thereto. <IMAGE> |
