Carrier wave migration method and device

The invention discloses a carrier wave migration method and device. The method comprises the steps that a carrier wave migration management module sends indication information to a source protocol stack, and the source protocol stack is instructed to carry out carrier wave migration preparing; when the carrier wave migration management module receives response information returned by the source protocol stack, a management server is informed and carries out carrier wave migration; the carrier wave migration management module receives carrier wave migration completing information sent by the management server; and the carrier wave migration management module sends informing information to a target server, the target server is informed of the fact that carrier wave migration is completed, and therefore carrier wave migration is achieved.
