Abstract: Transitioning between an audio only circuit switched call and a video call. A client device, which is currently connected to one or more other client devices through an established audio only circuit switched call, receives input from a user to transition from the audio only circuit switched call to the video call. A video call invitation message is transmitted to the other client devices. The client device receives a video call accept message from the other client devices and begins transmitting video captured by its front facing camera to the other client devices. Responsive to receiving at least a video frame from each of the one or more other client devices, the client device transitions from the audio only circuit switched call to the video call. After transitioning to the video call, the circuit switched call is dropped.

Abstract translation: 在仅音频电路交换呼叫和视频呼叫之间转换。 当前通过建立的仅音频电路交换呼叫连接到一个或多个其他客户端设备的客户端设备接收来自用户的输入以从仅音频电路交换呼叫转换到视频呼叫。 视频呼叫邀请消息被发送到其他客户端设备。 客户端设备从其他客户端设备接收视频通话接受消息，并开始将其前置摄像头捕获的视频发送到其他客户端设备。 响应于从一个或多个其他客户端设备中的每一个接收至少一个视频帧，客户端设备从仅音频电路交换呼叫转换到视频呼叫。 转换到视频通话后，电路交换呼叫被丢弃。
