Abstract

See full text

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.
