    Abstract: A device implementing a system for audio-video conferencing using multiple stream identifiers includes a processor configured to receive, from a sending device, indication of a first content stream and a first stream identifier, and indication of a second content stream and a second stream identifier associated. The first content stream and the second content stream correspond to different bit rates of streaming content. The processor is configured to receive, from a receiving device, a request to subscribe to the second content stream, the request including the second stream identifier, and receive, from the sending device, an indication that the second stream identifier has been associated with the first content stream. The processor is configured to forward, to the receiving device, the first content stream based on the request to subscribe to the second content stream and on the indication that the second stream identifier has been associated with the first content stream.

    Abstract: Conducting a real time application between a mobile device and a remote device. A first one or more messages may be transmitted to the remote device to establish a primary channel of communication for the real-time application. The primary channel may use a first radio access technology (RAT), such as WiFi or a cellular RAT. A second one or more messages may be transmitted to the remote device to establish a secondary channel of communication for the real-time application. The secondary channel may use a second RAT that is different from the first RAT. Data of the real-time application may be transmitted over both the primary channel and the secondary channel in a concurrent or redundant fashion.

    Abstract translation: 在移动设备和远程设备之间进行实时应用。 可以将第一个或多个消息发送到远程设备,以建立用于实时应用的主要通信通道。 主信道可以使用诸如WiFi或蜂窝RAT的第一无线电接入技术(RAT)。 可以将第二个一个或多个消息发送到远程设备,以建立用于实时应用的第二通信通道。 辅助信道可以使用与第一RAT不同的第二RAT。 实时应用的数据可以以主要信道和辅助信道以并发或冗余方式传输。

    Abstract: A device implementing cellular communication protocol aware multimedia streaming may include at least one processor configured to establish a link for communicating with another device, wherein the link utilizes at least one of a first cellular communication protocol or a second cellular communication protocol. The at least one processor may be configured to determine a bit rate for a video stream to be provided to the other device based at least in part on whether the link utilizes the first cellular communication protocol or the second cellular communication protocol, wherein a first bit rate is determined when the link utilizes the first cellular communication protocol and a second bit rate is determined when the link utilizes the second cellular communication protocol. The at least one processor may be configured to provide, for transmission over the link to the other electronic device, the video stream at the determined bit rate.
