A method and device for service transfer in automatically switched optical network are provided in the present invention, and the method includes: when a transfer node receives a transfer indication message, it sends an intercross information verification request to a transmission plane (S101); when the transfer node receives an intercross information verification success message, it performs a time slot resource transfer (S102); the transfer node determines whether it is the destination node of the present service transfer, if yes, an intercross connection transfer is performed directly, or else, after the indication signaling with the intercross connection transfer scene which is sent by the downstream node is received, the intercross connection transfer is performed (S103). The present invention improves the dependability of PC transferring to SPC, and further ensures the transfer dependability through the strict state control and state refresh mechanism. |
