Embodiments of the present invention disclose a method for implementing communication between different networks, where the method includes: receiving a multicast data obtaining request supporting a first network protocol, and determining multicast data identity information (MDID) of multicast data that needs to be obtained; obtaining, according to the MDID, in a multicast manner and from a network device supporting a second network protocol, the multicast data that needs to be obtained, and buffering the multicast data that needs to be obtained; establishing, for the multicast data that needs to be obtained, a multicast group supporting the first network protocol; and sending the multicast data that needs to be obtained by a user apparatus to the user apparatus which joins the multicast group supporting the first network protocol. The method of the present invention is simple, and is easy to be deployed and managed, and address mapping binding and protocol conversion based on a user apparatus do not need to be performed, and additional ALG support is not needed. |
