MULTIPOINT CONTROL UNIT CASCADED SYSTEM, COMMUNICATIONS METHOD AND DEVICE
First Claim
1. A Multipoint Control Unit (MCU) cascaded system, comprising a plurality of MCUs under the management of a service management center, wherein a cascade manner between the MCUs in the system is a reticulated cascade;
- the MCU is configured to receive information of a conference sent by the service management center;
the MCU is further configured to, according to the information of the conference, schedule the conference, establish link list information about all MCUs that are to attend the conference, and call other MCUs that are to attend the conference to join the conference;
the MCU is further configured to synchronize and obtain conference site information of the conference according to the link list information; and
the MCU is further configured to select, according to the conference site information of the conference, a path to send video and audio data.

Abstract
A Multipoint Control Unit (MCU) cascaded system is provided, which includes a plurality of MCUs under the management of a service management center. The cascade manner between the MCUs in the system is a reticulated cascade. A communications method for an MCU cascaded system, an MCU, and a service management center are also provided. In the embodiments of the present invention, because the connection and networking mode of MCUs in a cascaded system is changed, a transmission path passing the least MCUs can be selected according to a connection situation between the MCUs. Therefore, transmission delay and decrease of video and audio quality due to multiple forwarding by MCUs can be effectively avoided, and thus the media stream transmission time is reduced, and the play quality of the media stream is guaranteed in an overall manner.
