Abstract: A virtual machine start method and apparatus is presented, where the method includes determining N types of virtualized network function components (VNFCs) according to a first service; obtaining a distribution relationship between the N types of VNFCs and virtual machines, where the distribution relationship indicates a quantity of each type of VNFC distributed in each virtual machine; selecting at least one to-be-started virtual machine from unstarted virtual machines according to the distribution relationship, so that a total quantity of each type of VNFC included in a started virtual machine and the at least one to-be-started virtual machine meets a corresponding preset quantity; and starting the at least one to-be-started virtual machine. In the present disclosure, types and a quantity of VNFCs running on each virtual machine are first obtained.

Abstract: Embodiments of the present invention disclose a voice service handover method and a device, and relate to the communications field, so as to resolve a problem that reliability of a voice service of UE is reduced due to an exception that occurs on a network side of an LTE network. A specific solution is as follows: An MME determines that an exception occurs on a network side of an LTE network, where a voice bearer of target UE is established on the network side of the LTE network; and the MME sends, to an eNodeB, an SRVCC handover request message that carries an identifier of the target UE, so that the eNodeB hands over a voice service of the target UE from the LTE network to a CS network. The present invention is applied in a voice service handover process.
