摘要： For initially establishing a voice call, a first connection leg for the voice call is established between a mobile device operating in a wireless network and a conference room of a conferencing gateway. A second connection leg is established via the conferencing gateway between a processor and a communication device connected in a telephone network. Subsequently, the processor sends a message to the conferencing gateway for transferring the second connection leg from between the processor and the communication device to the conference room and the communication device, for initially establishing the voice call. The conference gateway is configured to combine media streams of connection legs of the voice call.

摘要： 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. During the voice call, a handover of the voice call from the WLAN to a wireless wide area network (WWAN) (e.g. GSM/GPRS) is identified. In response to identifying a handover indication, 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 to the communication device, so that a second connection leg between the communication device and the conference room may be established.

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）。
