ABSTRACT:
An RNC is divided into a plurality of user plane servers (UPSs) for executing the transmission control of user's data and a control plane server (CPS) for executing the transmission control of a control signal for transmitting user's data. A C plane control section for executing the transmission control of the control signal for transmitting the user's data is disposed in the CPS, and similarly a U plane control section for executing the transmission control of the user's data is disposed in each of the UPSs. A logical connection for transmitting control information is interposed between the U plane control section and the C plane control section. Hence, such a system, in which both the function of the C plane control and the function of the U plane control in the radio access controller (RNC) are physically divided into a plurality of devices, provides a simple control system, thereby making it possible to rapidly exchange the control information between the protocol entities.
