Abstract: A method of reducing tunneling in a wireless packet network. The method includes defining a home access point for a client station, determini ng that the client station is being serviced by an access point different from the home access point, deciding if the client station should change its home access point to the access point from which the client station receives service and initiating a change of the home access point of the client station, if so decided.

Abstract: A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the acces s point that uplink poll-based power save delivery mode will be used (614), an d the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with a response frame at an unspecified time within servic e window, during which time the mobile station maintains the WLAN subsystem power up and ready to receive the response frame. Upon successful receipt of the response frame, the mobile station places the WLAN subsystem back into a low power state.

Abstract translation: 移动台（106）经由用于承载语音或其他时间敏感数据的接入点（102）建立实时通信链路。 移动台的WLAN子系统（204）通常保持在低功率状态。 在发起通信链路时，移动台向接入点发信号通知上行轮询功率节省发送模式将被使用（614），接入点保留资源以确保必要的服务质量。 移动台通过首先加电WLAN子系统（712），获取WLAN信道（407）和发送轮询帧来发起帧事务。 在成功接收到轮询帧后，接入点准备在服务窗口内未指定的时间内用响应帧进行应答，在此期间移动台维持WLAN子系统加电并准备好接收响应帧。 在成功接收到响应帧之后，移动台将WLAN子系统置于低功率状态。
