Abstract: A call method includes: A first CSCF device receives a first communication message including first call signaling, where an originating party/calling party or a terminating party/called party of the first call signaling is roaming-in user equipment of the first CSCF device; and the first CSCF device enables, based on the first communication message, the first call signaling to be routed to an AS in the roaming area of the roaming-in user equipment, where the AS in the roaming area is an AS that is capable of providing a value-added-to-call service for user equipment and that is in a home area of the first CSCF device.

Abstract: In a method, a media delivery server may receive indication information that indicates a man-machine interaction environment of a user corresponding to UE during a call service execution period and that is sent by the UE. Then, the media delivery server may determine, based on the indication information, whether to deliver media content to the UE during the call service execution period. Alternatively, after receiving the indication information, the media delivery server may determine to-be-delivered media content based on the indication information, and deliver the to-be-delivered media content to the UE during the call service execution period. The indication information can reflect the man-machine interaction environment of the user during the call service execution period.

Abstract: A call processing method and call processing device are provided. The method provides a media server that receives an initial call request sent by a calling terminal and forwards the initial call request to a called terminal. The media server receives a success response to the initial call request from the called terminal, and performs video resource negotiation with the called terminal.
The media server sends, based on video resource negotiation with the called terminal, a video stream to the called terminal. In an audio call process between a calling user and a called user, a video stream can be sent to the called user. This improves user experience and improves network capability utilization.
