A method for implementing security of Single Radio Voice Call Continuity (SRVCC) is disclosed in the present invention. The method includes: after SRVCC handover, a calling party performing encrypted media stream interaction with a called party through a public switched telephone network media gateway; and the public switched telephone network media gateway encrypting media streams sent to the called party and decrypting the encrypted media streams sent from the called party; wherein, encryption keys in the public switched telephone network media gateway come from an enhanced mobile switch center. A system for implementing the security of SRVCC is also disclosed in the present invention. With the present invention, a key negotiation mechanism can be provided, which enables a terminal to still be able to perform secure sessions after the SRVCC handover.
