| 摘要: |
| 针对无线局域网（WLAN）多址接入的特点以及VoIP业务自身的质量要求，提出了一种设计方法，将上下行数据发送分离，支持实时业务的上下行对等传输，同时通过一种改进的早期随机检测（RED）算法，实现基于语音抖动参数的流量控制，为语音业务提供QoS保证。 |

| () |
| Abstract: |
| According to the multiple access properties of WLAN and the quality requirement of VoIP service,a system structure is presented which separates the uplink and downlink flow to support service with equal dual direction flow.A modified Random Early Detection(RED) algorithm is presented to realize flow control,thus providing QoS support for voice service. |
| Key words: WLAN VolP flow separating RED |
