METHOD FOR TRANSMITTING MULTICAST DATA BASED ON PROXY MOBILE IPV6

摘要

PURPOSE: A method for transmitting multicast data based on proxy mobile IPv6 are provided to exchange a multicast router and a multicast membership inquiry/report message through a MLD(Multicast Listener Discovery) forwarding proxy function, thereby improving efficiency of resource. CONSTITUTION: An AR(Access Router) receives a multicast membership inquiry message from a multicast MR(Multicast Router)(S210). The access router transmits the multicast membership inquiry message to a MN(Mobile Node). The access router receives multicast membership report message corresponding to the multicast membership inquiry(S220). The access router transmits the multicast membership report message to the multicast router. The access router transmits a multicast data from the multicast router to a mobile terminal(S230).
