A network switching processing method and device, the method including sending a switching message of switching from multimode single frequency radio voice call continuity (SRVCC) of a source network to a target network, judging whether a switching test success response message sent by a terminal in the target network is detected, and in the case where the judgement result is yes, determining that the terminal is successfully switched from the SRVCC of the source network to the target network. The method and device solve the problem whereby the verification conducted on the capability for a terminal to support SRVCC switching cannot be realized, thus achieving the effect of conducting valid verification on the SRVCC switching of a terminal.
