The radio access network for allowing to construct a system abundant in scalability in a W-CDMA mobile communication system. A RNC in the radio access network is physically separated into a C plane control equipment for controlling signaling and a U plane control equipment for processing user data, where the user data is transferred between a mobile terminal and a host device via only the U plane control equipment and a control signal is terminated by the U plane control equipment and the C plane control equipment. This allows a system abundant in scalability to be constructed, and even in the case of soft handover across the C plane control equipments, also enables the continuous use of the same U plane control equipment, thereby eliminating the conventional connection path for connecting between RNCs and preventing delay due to passing through the RNCs.
