Abstract
The invention discloses a dynamic channel configuration control method. When user equipment (UE) needs to update dynamic channel configuration control (DCCC) parameters, if the residual percentage of uplink code resources corresponding to the type of the UE in a service cell of the UE is larger than a preset cell residual code resource percentage threshold value, a radio network controller (RNC) configures the DCCC parameters according to a transmission-speed-quick-increasing-slow-decreasing strategy, and otherwise, the RNC configures the DCCC parameters according to a transmission-speed-slow-increasing-quick-decreasing strategy. When the UE is an R4 user, the corresponding uplink code resources are R4 uplink code resources, when the UE is a high-speed (HS) user, the corresponding uplink code resources are high-speed downlink packet accessing (HSDPA) uplink code resources. Speed adjusting parameters can be matched with a current network load state, accordingly, network performance can be improved, and user experience can be enhanced.
