The invention provides a centralized scheduling method and system, the method comprises the following steps: constructing MBS scheduling tree, and by sending the MSH-CSCF message along the broadcast scheduling scheduling tree tree information; MSS is sent to MBS through the MSH-CSCH request message request slot to transmit data; according to MBS receives the MSH-CSCH request message slot authorization and slot allocation for each MSS, and by sending a MSH-CSCH authorization message will inform each time slot allocation MSS scheduling tree in the MSS; according to the time slot of incoming MSH-CSCF messages and MSH-CSCH authorization message sending data acquisition. The invention is suitable for the time slot scheduling method of wireless Mesh network, and can realize the effective dispatching of resources.
