description Disclosed are a voice service switching method and device in single radio voice call continuity (SRVCC), the method comprising: recording, via an MME, whether a bearer deletion request message transmitted by a gateway device was received; if the MME determines that the bearer deletion request message was received, then the MME does not transmit the bearer deletion instruction message to the gateway device, and deletes a local voice service bearer resource, so after the MME deletes a voice service bearer at an IMS side, the MME does not delete a voice service bearer at an EPS side, thus avoiding SRVCC flow path conflict; alternatively, when a session termination reason is SRVCC switching, a PCRF does not transmit a re-authentication request message to the gateway device, that is, the gateway device at the IMS side does not perform a voice bearer deletion process, thus avoiding SRVCC flow path conflict; and alternatively, starting a delay timer on an IMS, and before the delay time expires, the IMS releases an I
