Claim:
1. A hitless multi-carrier spectrum migration method, wherein the method comprises: obtaining a spectrum of a secondary carrier and a to-be-migrated carrier in a target carrier group from a network management system, and generating the secondary carrier according to the spectrum of the secondary carrier; sending a migration notification to a peer network device, and performing answer response to a migration notification from the peer network device, wherein the answer response is used to determine that network devices at both ends can perform spectrum migration; sending first migration signaling to the peer network device, wherein the first migration signaling is used to instruct the peer network device to switch a service that is borne on the to-be-migrated carrier in the target carrier group to the secondary carrier; and receiving second migration signaling sent by the peer network device, and migrating, according to the second migration signaling, overhead information and the service that are borne on the to-be-migrated carrier in the target carrier group to the secondary carrier, wherein after the service that is borne on the to-be-migrated carrier is migrated to the secondary carrier, an idle spectrum corresponding to the to-be-migrated carrier and an adjacent idle spectrum form a consecutive idle spectrum area.
