摘要： If a handoff by a mobile station currently associated with a particular access point is probable, then the particular access point sends an activation alert to one or more other access points. An access point receiving the activation alert that is in a low-power state enters a higher-power state. An access point receiving the activation alert that is in a higher-power state, remains in that higher-power state.

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： In one illustrative technique, a contention-free period indication is communicated by a wireless access point (AP) (e.g. a battery-powered AP) to a plurality of mobile communication devices within a beacon of a superframe. The contention-free period indication identifies a duration of a contention-free period within which the mobile devices must refrain from communicating through the AP. During each contention period subframe of each superframe, information is communicated to and/or from the mobile devices through a wireless transceiver of the AP. During each power conservation subframe of each superframe, the wireless transceiver is placed into a power conservation mode which is at least part of the contention-free period. Alternatively, or in combination with the wireless transceiver being placed in the power conservation mode, information for the mobile devices may be communicated to and/or from another AP within each relay subframe of each superframe which is at least part of the contention-free period. Advantageously, power consumption may be reduced in the AP and/or a single radio interface may be utilized in the AP for communications. The durations of the power conservation subframe and the other subframes may be variably adjusted to tradeoff power savings with a real-time capacity requirement of the AP.

摘要： Intra-enterprise wireless handset (WH) calls between WHs operating in a wireless local area network (WLAN) are established directly between the WHs via a call connection that is maintained within the LAN without being routed through the cellular network (CN). This eliminates the cost of placing and maintaining calls through the CN for intra-enterprise calls, and also enables use of capabilities that are available in the enterprise telecomm equipment. Upon detection of a trigger condition, if and when it is more likely that a complete vertical handover (VHO) may be needed, the call connection between the WHs in the LAN is replaced by one that is routed through the CN. Thereafter, a VHO may occur (if at all) upon detection of a radio handover condition.
摘要翻译：无线局域网（WLAN）之间的企业间无线手机（WH）呼叫直接通过在LAN内维护的呼叫连接在WH之间建立，而不通过蜂窝网络（CN）进行路由。这消除了通过CN拨打和维护用于企业内呼叫的呼叫的成本，并且还能够使用企业电话设备中可用的功能。在检测到触发条件时，如果可能需要完整的垂直切换（VHO）更可能，LAN中的WH之间的呼叫连接将被通过CN路由的呼叫连接所取代。此后，当检测到无线电切换条件时，可能发生VHO（如果有的话）。

摘要： In one illustrative example, a mobile communication device operating in a wireless local area network (WLAN) of a communication network maintains an inter-enterprise voice call via its WLAN interface (e.g. 802.11/VoIP/SIP) with another communication device in the communication network. Communications of the voice call are maintained solely within the communication network and not routed through a conferencing gateway. During the voice call, a handover of the voice call from the WLAN to a wireless wide area network (WWAN) (e.g. GSM/GPRS) may or may not be required. In response to identifying a handover indication during the voice call, the mobile device causes a request message (e.g. a SIP INVITE message) to be sent over the WWAN to the conferencing gateway for establishing a first connection leg through the WWAN via its WWAN interface with a conference room of the conferencing gateway. The mobile device also causes a re-routing message (e.g. a SIP REFER message) to be sent over the WLAN to the communication device so that a second connection leg between the communication device and the conference room of the conferencing gateway may be established. The first and the second connection legs are connected together in the conference room of the conferencing gateway for the voice call. Advantageously, inter-enterprise voice calls in the communication network need not unnecessarily and unduly burden the conferencing gateway, unless and until a handover of the voice call between the WLAN and the WWAN is required. Variations and other PSTN conferencing gateway techniques are also described.
摘要翻译：在一个说明性示例中，在通信网络的无线局域网（WLAN）中操作的移动通信设备通过其WLAN接口（例如，802.11 / VoIP / SIP）与通信网络中的另一通信设备维护企业间语音呼叫。语音呼叫的通信仅保持在通信网络内，而不通过会议网关路由。在语音呼叫期间，可以或不需要将语音呼叫从WLAN切换到无线广域网（WWAN）（例如GSM / GPRS）。响应于在语音呼叫期间识别切换指示，移动设备使得请求消息（例如，SIP INVITE消息）通过WWAN发送到会议网关，用于经由其WWAN经由其WWAN接口建立第一连接腿，会议网关的会议室。移动设备还引起将重新路由消息（例如，SIP REFER消息）通过WLAN发送到通信设备，使得可以建立通信设备和会议网关的会议室之间的第二连接分支。第一和第二连接腿在会议网关的会议室中连接在一起，用于语音呼叫。有利的是，除非需要WLAN和WWAN之间的语音呼叫切换，否则在通信网络中的企业间语音呼叫不需要不必要地过度地加重会议网关。还描述了变型和其他PSTN会议网关技术。
