摘要： A system and method of reducing the WLAN power consumption and limiting battery drain of a mobile communications device is provided. The mechanism continuously monitors for changes in the WLAN and cellular signal strength and modifies the WLAN profile scanning activity accordingly. By monitoring for changes, transitions can be detected which indicate the location of the mobile device (i.e., indoor or outdoor). An increase in cellular signal strength and a decrease in WLAN signal strength indicates the user is transitioning outdoors where WLAN coverage may be limited. To reduce battery power consumption, background scanning is suspended or its frequency significantly lowered. Moving indoors is indicated by a decrease in cellular signal strength and an increase in WLAN signal strength. Background/Connectivity scanning frequency is increased to provide shorter time-to-connect to WLAN Networks for the user within the WLAN coverage area.
摘要翻译：提供了降低WLAN功率消耗并限制移动通信设备的电池消耗的系统和方法。该机制持续监控WLAN和蜂窝信号强度的变化，并相应地修改WLAN配置文件扫描活动。通过监视变化，可以检测到指示移动设备（即室内或室外）的位置的转换。蜂窝信号强度的增加和WLAN信号强度的降低表明用户正在向室外转移WLAN覆盖可能受到限制。为了减少电池功耗，背景扫描被暂停或其频率显着降低。移动室内由蜂窝信号强度的降低和WLAN信号强度的增加来表示。增加背景/连接扫描频率，以便为WLAN覆盖区域内的用户提供更短的时间连接到WLAN网络。

摘要： An emergency locator component for a mobile communication device enables the mobile communication device to obtain location information from other neighbouring mobile devices in the event that the mobile communication device is unable to determine its own location. The mobile communication device employs a short-range radiofrequency transceiver to broadcast a request for location information to the neighbouring mobile devices. A response containing location information may be received from another mobile device equipped with a similar emergency locator component. Accordingly, this technology enables mobile devices to exchange location information by setting up an ad-hoc network. The location information can be included, for example, in an emergency phone call to an emergency services call center.
摘要翻译：用于移动通信设备的紧急定位器组件使得移动通信设备能够在移动通信设备不能确定其自己的位置的情况下从其他相邻移动设备获得位置信息。移动通信设备使用短距离射频收发器向相邻移动设备广播对位置信息的请求。可以从配备有类似的紧急定位器组件的另一移动设备接收包含位置信息的响应。因此，该技术使得移动设备能够通过建立自组织网络来交换位置信息。位置信息可以包括在例如紧急电话呼叫中的应急服务呼叫中心。

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.
摘要翻译：提出了一种用于使VoIP通信的分组大小适应的方法，其通过在分组传输时固有的总网络延迟来实时确定。如果网络延迟相对于VoIP通信的最大允许延迟来说较小，则可以增加每个分组的有效载荷大小以最大化传输呼叫的效率。或者，如果网络延迟较大，则可以减少每个分组的有效载荷大小，以便确保所发送的呼叫的感知质量是可接受的。

摘要： A target access point is selected from the results of a discovery scan so that a mobile station can attempt a connection with the target access point. The mobile station determines whether the target access point belongs to a small office/home office (SOHO)-type wireless local area network (WLAN) deployment or to a corporate/enterprise-type WLAN deployment. The mobile station then configures itself according to the determination of the type of WLAN deployment to which the target access point belongs.

摘要： Techniques for efficient scanning for WLANs based on mobile device velocity are described. In one illustrative example, a mobile device identifies whether its velocity is less than or greater than a threshold value. While it is identified that the velocity of the mobile device is less than the threshold value, the mobile device scans to search for one or more WLANs identified in a first subset of WLAN profiles (e.g. “stationary” WLANs). While it is identified that the velocity of the mobile device is greater than the threshold value, the mobile device scans to search for the one or more WLANs identified in a second subset of WLAN profiles (e.g. “mobile” WLANs). Advantageously, a suitable WLAN may be more efficiently identified with use of a technique which reduces power consumption of the mobile device.

摘要： Techniques for use in controlling an access point mode of operation of a mobile terminal are described. Initially, the mobile terminal operates in the access point mode of operation for communication with one or more other mobile terminals. While operating in the access point mode, the mobile terminal receives, from the one or more other mobile terminals, network information comprising one or more network identifiers which identify one or more wireless networks within coverage of the one or more other mobile terminals. The mobile terminal disables the access point mode of operation in response to identifying that at least one of the received network identifiers corresponds to a predetermined wireless network or predetermined type of wireless network. In one example, the mobile terminal is operative in accordance with IEEE 802.11, the received network identifiers comprise service set identifiers (SSIDs), and the predetermined wireless network is an enterprise network.

摘要： A wireless client device associated with an access point records at which time T after a transmission time of a most recent beacon frame it gained access to the wireless medium for transmission of an uplink packet to the access point. The wireless client device self-schedules target transmission times for one or more future uplink packets, where each of the target transmission times is T after a respective expected transmission time of a beacon frame. Rather than immediately attempting to gain access to the wireless medium when it determines that another uplink packet is ready for transmission, the wireless client device waits until shortly before its next upcoming target transmission time to make the attempt. Implementation in wireless client devices that are attempting to transmit uplink packets to the same access point may prolong the amount of time they can remain in a doze state, potentially reducing their power consumption.
摘要翻译：与接入点相关联的无线客户端设备记录在其最近的信标帧的传输时间之后的时间T，该最近的信标帧获得对无线介质的访问，以将上行链路分组传输到接入点。无线客户端设备自动调度一个或多个未来上行链路分组的目标传输时间，其中每个目标传输时间在信标帧的相应预期传输时间之后为T。无线客户端设备在确定另一个上行链路分组已准备好进行传输时立即尝试获得对无线介质的访问，而不会在其下一个即将到来的目标传输时间之前等待，以进行尝试。在尝试将上行链路分组传输到同一接入点的无线客户端设备中的实现可以延长它们可以保持在打盹状态的时间量，这可能降低其功耗。
