Abstract
Embodiments of the present invention provide a state transition control method, a multipoint control server, and a videoconferencing system. The method includes: receiving, by a multipoint control server, a conference reservation message, where the conference reservation message carries start time and end time of a reserved conference and an identity of a site centralized control device at a site participating in the reserved conference; and sending a state transition command to the site centralized control device according to the start time and the identity or according to the end time and the identity. In the embodiments of the present invention, through centralized control, in a non-conference state, external devices in a videoconferencing system enter a power-off state, and in a conference state, devices in the videoconferencing system are recovered to a normal working state, thereby improving user experience and reducing power consumption of the videoconferencing system.
