Abstract
A method includes transferring a general query message to managers of a mobility control server in response to receiving, from a router, the general query message for detecting a mobile node that requested to receive multicast data; storing, in a multicast mapping table, an address of the mobile node that requested to receive the multicast data when a membership report message of the mobile node is received from at least one of the managers and transferring the membership report message to the router; and forming a tunnel between the router and a manager that transfers the membership report message.
