Control system, control method, and radio network controller preferably used for the system and method

摘要

It is an object of the present invention to provide a control system capable of maintaining communication quality, decreasing transmission delay, and simultaneously connecting with numerous mobile stations (40) in a mobile packet communication system. The control system of the present invention controls the information rate of a shared channel (DSCH) in a mobile packet communication system for time division multiplexing and transmitting data signals addressed to a plurality of mobile stations (40) through a shared channel (DSCH) and transmitting control signals addressed to the mobile stations through dedicated channels (A-DPCHs). The control system is provided with a dedicated channel number monitoring unit (25) for monitoring a change in the number of dedicated channels (number of simultaneously connected A-DPCHs) and an information rate controlling unit (24) for controlling the information rate of the shared channel (DSCH) according to the detection result when a change in the number of dedicated channels (number of simultaneously connected A-DPCHs) is detected.
