The invention provides a method and a system for realizing a safe bifurcation call session in an IP multimedia system. In the invention, based on Otway Rees key agreement protocol, a key agreement system is provided and is enabled to realize the safe bifurcation call session in the IP multimedia subsystem (IMS). When a called party receives a call, a slave calling key management server (KMS) acquires a media root key K used for deriving media keys; then based on a random number and the media root key K which are derived by each called party, each called party and each calling party can derive a media key respectively by utilizing a media key deviation function (KDF). The media key of each called party is unique and cannot be learned by other terminals, thereby realizing media safety of the bifurcation call session. The invention has simple logic, reduces computing and processing pressure of the calling party, interacts less with a KMS signaling, relieves storage and computation requirements for the KMS, and excellently provides the safety protection for ensuring the bifurcation call session for the IMS.
