The invention relates to a method for dispatching MCU resource of a video conference system , which applies a dispatching subsystem of a video conference system resource to uniformly manage all the MCU resources within the management scope. The invention includes: a reservation request from a consumer is received; an optional MCU subset is calculated according to an IP resource corresponding to the MCU required by the reservation request and an IP resource consumed by each MCU inside all the MCU resource sets; then the MCU is selected from the optional MCU subset until a verification is passed or all are selected in turn; at last, a result is returned. The method conducts automatic selection within all the MCU resources managed by the system and replaces static MCU distribution with dynamic MCU distribution, thereby not needing any number of a distribution terminal ,realizing automatization and easing management and utilization; furthermore, the MCU with the most IP resources is selected to realize a balance load, and the success rate of resource reservation is guaranteed at a most extent through resource verification, and thus the maximal utilization of MCU hardware investment ofoperator is guaranteed.
