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： 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部呼叫的呼叫的成本，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： A method, mobile electronic device and system for synchronizing hand-off of a voice media session between a WAN/cellular network and a WLAN network. When a hand-off occurs, the connection with both networks is temporarily maintained and the voice data on both connections compared to determine differences in the delays experienced over both connections. The timing of one or both voice streams is adjusted to synchronize the voice streams, and then the handoff is completed.

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： One illustrative method of providing network broadcast information to a wireless device from a wireless local area network (WLAN) includes the steps of receiving, from one or more available cellular networks or a network database, cellular network broadcast information associated with the one or more available cellular networks; providing the cellular network broadcast information in a generic container message which varies in content and format according to one or more cellular standards associated with the one or more available cellular networks; and causing the generic container message to be regularly broadcasted for receipt and use by a wireless device. In an alternative approach, the steps include regularly broadcasting a network interworking indicator which is indicative of whether cellular network broadcast information is available for receipt from the WLAN; receiving a probe request from a wireless device; and causing the cellular network broadcast information to be sent to the wireless device in the generic container message in response to the probe request from the wireless device, The generic container message may alternatively or additionally include wireless network broadcast information from different types of wireless networks (e.g. Wi-MAX) which are available to the WLAN.
