    • Handover of a call to a dual-mode phone from cellular to Wi-Fi. When handing over a call mediated by a mobility controller to a dual-mode phone and switching the call from a cellular to a Wi-Fi call, the mobility controller initates a Wi-Fi connection to the dual mode phone. When the Wi-Fi connection is established, and with the cellular connection through the mobility controller still in place, the mobility controller starts a timer with a predetermined value and the dual-mode phone initiates release of the cellular connection. When the timer expires, the mobility controller switches the call from the cellular connection to the Wi-Fi connection.
    • 从蜂窝移动到Wi-Fi的双模手机呼叫切换。 当将由移动性控制器调用的呼叫转移到双模手机并将呼叫从蜂窝电话切换到Wi-Fi呼叫时,移动性控制器启动到双模手机的Wi-Fi连接。 当建立Wi-Fi连接并且通过移动性控制器的蜂窝连接仍然存在时,移动性控制器启动具有预定值的定时器,双模手机启动蜂窝连接的释放。 当定时器到期时,移动控制器将呼叫从蜂窝连接切换到Wi-Fi连接。

    • Improved handling of RTP streams in digital networks. A switching device in a digital network such as a controller, bridge, or access point examines streams flowing through the device. The device monitors the initial UDP packets of a stream until a predetermined number of packets have been monitored. The device monitors and fingerprints the header portion of UDP packets, looking for RTP header bit patterns, ignoring certain RTP packet types, and caching others. This fingerprinting process attempts to match cached packet header information against subsequent packets in the stream to detect RTP streams. If the stream is determined to be an RTP stream, then the RTP type from the packet header is used to tag the stream. In one embodiment, such tags are QoS tags. Tagging may also be based on the control session port used.
    • 改进数字网络中RTP流的处理。 诸如控制器,桥接器或接入点之类的数字网络中的交换设备检查流经设备的流。 该设备监视流的初始UDP分组,直到已经监视预定数量的分组。 该设备监视和指纹UDP数据包的头部,查找RTP头位位模式,忽略某些RTP数据包类型,并缓存其他数据包。 该指纹过程尝试将缓存的分组报头信息与流中的后续分组相匹配,以检测RTP流。 如果流被确定为RTP流,则使用来自分组报头的RTP类型来标记流。 在一个实施例中,这样的标签是QoS标签。 标记也可以基于所使用的控制会话端口。
