无线局域网中用于实时通信的基于上行链路轮询的功率节约传递方法技术

移动台（１０６）经由接入点（１０２）建立实时通信链路，用于运载语音或其他随时间变化的数据。移动台的ＷＬＡＮ子系统（２０４）通常处于低功率状态。当启动通信链路时，移动台通知将使用接入点基于上行链路轮询的功率节约传递模式（６１４），并且接入点保留资源以确保所需的服务质量。移动台通过首先启动ＷＬＡＮ子系统（７１２）、获取ＷＬＡＮ信道（４０７）并发送轮询帧启动第一处理。当成功接收轮询帧时，接入点准备在服务窗口内的未指定时间使用响应帧回复，在该时间期间移动台保持ＷＬＡＮ子系统唤醒并准备接收响应帧。当成功接收响应帧时，移动台将ＷＬＡＮ子系统放置回到低功率状态。

Power saving transmission method based on uplink polling for real-time communication in wireless local area network

The mobile station (106) establishes a real time communication link through the access point (102) for carrying voice or other time varying data. The WLAN subsystem (204) of the mobile station is usually in a low power state. When the communication link is started, the mobile station informs that the access point is based on the power saving transmission mode (614) of the uplink polling, and the access point retains the resources to ensure the required quality of service. The mobile station starts the first processing by starting the WLAN subsystem (712), obtaining the WLAN channel (407) and sending the polling frame. When the polling frame is successfully received, the access point is ready to respond to the frame reply in the service window at an unspecified time, during which time the mobile station maintains the WLAN subsystem and is ready to receive the response frame. When the response frame is successfully received, the mobile station places the WLAN subsystem back into a low power state.
