The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transitioning a video call between networks","description":"A method for transitioning a video call is provided.
