MEDIA SESSION PROCESSING METHOD, RELATED DEVICE, AND COMMUNICATIONS SYSTEM

摘要

Embodiments of the present invention disclose a media session processing method, a device, and a system. The method may include: determining, by a first media device, global priorities of media streams corresponding to N media sources, where the N media sources are N media sources that can be provided by the first media device in a media session in which a second media device participates, and one of the N media sources corresponds to at least two media streams used to be simulcast in the session; and when a transmission path between the first media device and the second media device is congested, performing, based on the determined global priorities of the media streams corresponding to the N media sources, congestion control on the media streams corresponding to the N media sources that are sent by the first media device to the second media device.
