The example video calling service offers a seamless transition of a voice call to a video call in a simplified and efficient process. In an example, a graphical user interface is provided that allows a user to select controls to provide real-time stream of video of a live scene via a rear facing camera to another user during a video call. Other examples describe the merger of individual voice calls into a merged call with the individual calls grouped as a conference call. The examples provide simplified use of a mobile device to transition voice calls to a video call in a cellular carrier's mobile network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voice and video calling over long term evolution-based user interface","description":"A video calling service provides a mobile device user is provided the capability to transition from a voice call to a video call within a calling session in a voice over long term evolution (VoLTE).
