The invention discloses a buffer queue threshold configuring method and device, for dynamically configuring MAC-hs buffer queue threshold in wideband code division multiple access (WCDMA) system, and arranging at least two data waiting delay parameters in buffer queue; obtaining data output velocity V in the buffer queue; and using the product of each waiting delay parameter and data output velocity V to configure the threshold of the current buffer queue. And it also discloses a flow control method and device, after the above threshold is updated, regulating data input bandwidth of the buffer queue and making flow control. According to the data output velocity of the buffer queue, it correspondingly regulates the buffer queue threshold and controls the flow, thus making the data length in the buffer queue being in a proper range, and assuring the buffer queue can provide enough data for aerial interface to transmit, reducing data length in the buffer queue and data processing waiting time. |
