Patent attributes
Systems and methods for providing additional video call transfer functionality are disclosed. The systems and methods can enable a video call between a first user equipment (UE) and a second UE to be transferred to a video call between the second UE and a third UE either a video call or an audio call. The systems and methods can also enable the third UE to accept a transferred video call or to request that the video call be downgraded to an audio call. The systems and methods can incorporate a multimedia resource function (MRF) to connect to the second UE while the transfer is being negotiated and effected. The MRF can provide an audio stream and a video stream to the second UE to provide a “video hold” feature—to prevent the video call from dropping to an audio call automatically or dropping altogether.
