A method for implementing a multimedia RBT service includes: receiving, by an calling MSC server, a call request from a calling party; performing a first media capability negotiation between a calling party and an MRS, after detecting a response of a called party; and instructing the MRS to play a multimedia RBT to the calling party according to a result of the first media capability negotiation. A system for implementing the multimedia RBT includes: an MSC server and an MRS. In accordance with embodiments of the invention, a multimedia RBT service may be implemented in the 3G network, thereby enabling an original audio RBT service in a hybrid 3/2G network and the 3G network to coexist with the multimedia RBT service, and ensuring the normal use of an RBT service.
