摘要： A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality of the transmitted call is acceptable.

摘要： Example methods and apparatus to manage wireless device power consumption are disclosed. In accordance with a disclosed example method a data frame exchange is initiated with an access point of a wireless network. In response to not successfully completing the frame exchange with the access point, the access point is designated as providing the wireless terminal with fringe wireless signal coverage.

摘要： Methods and apparatus for controlling a wireless access point (AP) (e.g. a battery-powered wireless AP) for reduced power consumption are provided. In one illustrative example, the AP is adapted to provide communication access for end stations in one or more activated service intervals of each superframe. During operation, the AP changes the number of activated service intervals that are available to end stations for the communication access, as well as the durations of their active subinterval durations, in accordance with a change in traffic requirements. The AP regularly broadcasts data which indicates the activated service intervals that are made available to the mobile devices. A wireless transceiver of the AP is enabled during each activated service interval made available to the mobile devices, but the AP is placed in a power conservation mode during each deactivated service interval provided in between the activated service intervals. The AP may also be placed in the power conservation mode during inactive subintervals of each activated service interval.

摘要： An Access Point (AP) advertises the availability of notifications, and this advertisement may be received and interpreted by stations (STAs), both by associated STAs and by non-associated STAs. Upon being informed of the availability of the notification message, a STA may be able to identify the notification message by analyzing the advertisement. If the contents of the notification message comprise a control message, the STA may act on the control message in a way that influences the STA's behavior. If the contents of the notification message indicate restrictions imposed by the AP, the STA may determine, in view of the restrictions, not to attempt association with the AP.
