A system and a method for performing a multicast service are disclosed. In accordance with embodiments of the present invention, an Application Layer Gateway Subsystem set in the network side handles application layer protocol messages communicated between the network side and a UE, and triggers, according to a handling result of the application layer protocol messages, a Multicast Carrier Management Subsystem set in the network side to configure and manage multicast paths in the bearer network, including establishing and deleting the multicast paths. In accordance with the embodiments of the present invention, because the application layer protocol and the multicast management protocol are combined with each other effectively, it is convenient to manage a multicast network, provide an operator with flexible operation management through the application layer protocol, and the security of the multicast service may be guaranteed.
