Abstract: A video conference scheduling method and apparatus relates to the communications field. A conference reservation reference list can be ultimately obtained by acquiring reservation information of each conference site and quality of service (QoS) description information sent by each conference site and performing statistical analysis on the QoS description information and the reservation information, so that a user can select an optimal reservation scheme from the conference reservation reference list according to a conference site and time that the user wants to reserve, which avoids a problem that a conference cannot be normally held because of a poor network status, realizes effective arrangements for the conference, and improves work efficiency, thereby reducing a waste of conference resources, human resources, and time caused by an unsuccessful conference. The method is applied to video conference scheduling.
