The present invention discloses a single radio voice call continuity handover method and apparatus. An MME records whether a bearer deletion request message sent by a gateway device is received, and if the MME determines that the bearer deletion request message is received, the MME does not send a bearer deletion instruction message to the gateway device, and does not delete a local voice service bearer resource. Therefore, after the MME performs voice service bearer deletion on an IMS side, the MME does not perform voice service bearer deletion on an EPS side, thereby avoiding a conflict in an SRVCC process. Alternatively, when a reason for session termination is SRVCC handover, a PCRF does not send a re-authentication request message to the gateway device, that is, the gateway device does not perform a voice bearer deletion process on the IMS side, thereby avoiding a conflict in an SRVCC process.
