Abstract

The invention provides a forward supplement channel speed assignment method, a forward supplement channel speed assignment device and a base station. The forward supplement channel speed assignment method comprises the following steps of: determining forward supplement channel (F-SCH) speed to be assigned in the dispatching cycle according to the wireless condition of a terminal and the power load of a load fan of a base station; adjusting the determined F-SCH speed according to the power fluctuation condition of the F-SCH in the last dispatching cycle; and assigning the F-SCH speed of the dispatching cycle according to the adjusted F-SCH speed. In the invention, the speed is assigned for the terminal according to the instantaneous wireless condition of a user and the power condition of the load fan, and extra speed reduction processing is performed on the terminal with serious fluctuation by evaluating the historical power fluctuation condition of the F-SCH of the terminal, so that unreasonable speed assignment caused by instantaneous sampling is avoided, and power overload of the load fan caused by the improvement on the transmission power of the F-SCH is relieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a forward supplementary channel rate assignment method, device and base station. Background technique [0002] The high-speed packet data service provided by the CDMA2000 base station system is carried over the air by SCH (Supplemental Channel, Supplementary Channel), wherein the SCH from the base station to the terminal is F-SCH (Forward-Supplemental Channel, Forward Supplemental Channel). Since the F-SCH requires greater transmission power than the basic channel carrying voice services, the increase in transmission power will cause overload of the radio frequency system. And under the same wireless environment, higher rate F-SCH requires higher transmission power. Therefore, when the F-SCH is established, it is very important to assign an appropriate rate to prevent the overload of the radio frequency system caused by the forward power increase and to stabilize the system pe...
