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.
