The invention discloses a method to realize the SPC activation/ deactivation by a control plane in the ASON network, which can realize the creation, activation, deactivation and deletion of soft permanent connection SPC based on the control plane CP in the ASON network, the resource is pre-reserved during the creation, the transmission plane is noticed to establish the configuration of cross connection after receiving the activation instruction of the management plane MP, finally the SPC connection is established; before the deletion of SPC, the activation instruction is firstly sent out to notice the transmission place to delete the cross connection, the CP continues to reserve the pre-reserved resource, the pre-reserved resource is released after receiving the deletion instruction and the complete deletion for the SPC connection is finally realized. The invention can facilitate the operation and maintenance of the network by the operation and maintenance people, provide the restoration of the pre-calculation function and effectively improve the survival of the network; and the resource pre-reserved function can ensure the flexibility of the businesses which are provided by the operators.
