  • Video calling method and device based on voice over long-term evolution and video over long-term evolution, and mobile terminal
    Patent number: 9800625
    Abstract: VoLTE based video calling method and device and a mobile terminal are provided. The method includes: receiving a request for VoLTE video calling from a user at a first UE; sending a session request message which carries a first video parameter supported by the first UE to a second UE through an EPS network; receiving a video QoS parameter sent by the EPS network; receiving a session response message sent through the EPS network by the second UE, the session response message carrying a second video parameter provided by the second UE which is determined based on the video QoS parameter and the first video parameter; determining a third video parameter for the first UE based on the video QoS parameter and the second video parameter; and initiating a VoLTE video calling using the third video parameter. Relatively good video calling quality may be obtained in different VoLTE networks.
