The present invention relates to the technical field of communications. Disclosed in embodiments of the present invention are a time calibration method, device and system capable of timely calibrating a system time of a virtual machine, thus ensuring that a service dependent on the system time of the virtual machine will not be affected. The specific solution is: receiving, by a VNFM, a live migration notification message transmitted by a VIM after a first virtual machine undergoes a live migration, the live migration notification message comprising an ID of the first virtual machine; querying, by the VNFM according to the ID of the first virtual machine, a corresponding relationship stored in the VNFM between an ID of a virtual machine and an identifier of a service control VNF, and determining a first service control VNF, an identifier of the first service control VNF and the ID of the first virtual machine corresponding to the VNFM; and transmitting the live migration notification message to the first service control VNF, the live migration notification message being configured to instruct the first service control VNF to calibrate a system time of the first virtual machine. The embodiments of the present invention are applied to virtual machine undergoing live migration. |
