    • Disclosed are techniques for hosting a communication session in a call server between communication devices. The call server functions as a bridge service between the communication devices joining an original communication link between the first communication device and the call server with a second communication link between the second communication device and the call server. The first communication device includes at least two RF transceivers each capable of communicating with the call server over a separate network. The call server receives a signal from the first communication device indicative of the need to handoff the original communication link to an alternate communication link on an alternate network. The call server establishes the alternate communication link with the first communication device on the alternate network and joins it with the second communication link to maintain the communication session between the communication devices.
    • 公开了用于在通信设备之间的呼叫服务器中托管通信会话的技术。 呼叫服务器在通过第二通信设备和呼叫服务器之间的第二通信链路加入第一通信设备和呼叫服务器之间的原始通信链路的通信设备之间起到桥接服务的作用。 第一通信设备包括至少两个RF收发器,每个RF收发器能够通过单独的网络与呼叫服务器进行通信。 呼叫服务器从第一通信设备接收指示需要将原始通信链路切换到备用网络上的备用通信链路的信号。 呼叫服务器与替代网络上的第一通信设备建立备用通信链路,并将其与第二通信链路相连,以保持通信设备之间的通信会话。

    • Examples are disclosed for mediating a voice communication session in which a communications server functions as a bridge service between a hybrid mobile device and a second endpoint. The communications server sends, over a downstream link, and receives, over an upstream link, an Internet Protocol (IP) packet data media stream representing the voice communication session over a WiFi IP data communication link to and from the hybrid mobile device. The communications server is also capable of sending, over a downstream link, and receiving, over an upstream link, a second IP packet data media stream representing the same voice communication session over a cellular IP data communication link to and from the hybrid mobile device. The communications server monitors the quality of service (QoS) of the IP packet data media stream as determined by multiple communication link parameters for the 802.11 WiFi network connection. When the communication link parameters dip below a specified QoS, the communications server interleaves a help packet into the downstream IP packet data media stream instructing the hybrid mobile device to begin streaming the IP packet data media stream representing the voice communication session over the upstream link of the cellular IP data communication link in addition to and in sync with the IP packet data media stream being sent over the upstream link of the WiFi IP data communication link.

    • Examples are disclosed for hosting a communication session between a computer device and a destination communication device in an Internet Protocol (IP) based packet data network. A computer device receives multiple concurrent IP packet data streams each representative of the same content but received over corresponding multiple communication links. The original IP packet data stream comes from the communications server. At least one IP packet data stream representative of the original IP packet data stream traverses a communication link through a second communication device working in tandem with the communications server before arriving at the computer device. The computer device determines a highest quality packet for each corresponding packet in the multiple concurrent IP packet data streams. The computer device then creates a bonded IP packet data stream by selecting the highest quality packet for each time slot from among corresponding time slots of the multiple concurrent IP packet data streams.

    • Techniques are disclosed for evaluating an ongoing VoIP call over a combination of IP data communication network connections for purposes of determining when to hand it off to a circuit-switched cellular network connection. Multiple IP stream call quality values X1(i), X2(i), and Xb(i) are sampled over a time period (N) of (j) samples for an ongoing telephone call and stored. Instantaneous annoyance values a1(j), a2(j), and ab(j) for each of the stored call quality values for each of the IP streams within sampled time period (N) are calculated. Current accumulated annoyance values A1(i), A2(i), and Ab(i) are obtained by summing the instantaneous annoyance values a(j) for each IP network. The combined IP stream accumulated annoyance values Ab(i) is compared to a handoff threshold values Hb(i). A handoff of the telephone call a circuit-switched cellular communication link is initiated when the accumulated annoyance value Ab(i) is greater than the handoff threshold value Hb(i).
