Abstract
Provided is a method of transmitting multicast data based on proxy mobile Internet protocol version 6 (PMIPv6) during handoff. The method includes, when a first access router detects that a mobile node in the region of the first access router moves out of the region, transmitting, at the first access router, a context message informing a second access router adjacent to the first access router of handoff, when the second access router receives the context message, transmitting, at the second access router, a multicast membership report message about the mobile node to a multicast router, and receiving, at the second access router, multicast data from the multicast router and holding the received multicast data.
