<p>A connection transfer method in an automatically switched optical network is provided in the present invention, wherein the node exchanges standard signaling with related nodes to perform the connection transfer. In the method, the transfer state bit field that is used to identify the transfer operation state is set in the connection information, the signaling scene information is carried in said standard signaling, the node performs signaling scene state conversion, and completes the mutual transfer between the permanent connection PC and the soft permanent connection SPC according to the signaling scene information carried in the standard signaling and the value of the current transfer state bit. A connection transfer system in an automatically switched optical network is also provided. The method and system of the present invention ensure that resources will not be mistakenly cancelled when a cancelling signal is received, and further, that a PC is guaranteed after the failure of an SPC transfer to PC or a PC transfer to SPC.</p> |
