Abstract
A multicast communication method is disclosed that includes the steps of: (a) transmitting a position registration request including multicast join request information from a mobile node to a network; (b) receiving the position registration request, performing position registration, and setting session information data for performing a multicast communication in a home agent connected to the network; and (c) encapsulating a multicast packet and forwarding the multicast packet to an optimal forwarding destination on the network to which the mobile node to join the multicast communication is connected based on the session information data in the home agent that has received the multicast packet from the network.
Claims14
A multicast communication method, comprising the steps of:
- (a) transmitting a position registration request including multicast join request information from a mobile node to a network;
- (b) receiving the position registration request, performing position registration, and setting session information data for performing a multicast communication in a home agent connected to the network;
- and
- (c) encapsulating a multicast packet and forwarding the multicast packet to an optimal forwarding destination on the network to which the mobile node to join the multicast communication is connected based on the session information data in the home agent that has received the multicast packet from the network.
A home agent, comprising:
- a position registration part configured to receive a position registration request including multicast join request information transmitted from a mobile node to a network, create position registration information data, and perform position registration;
- a session setup part configured to set session information data for performing a multicast communication from the position registration request including the multicast join request information and the position registration information data;
- and
- a forwarding part configured to encapsulate a multicast packet and forward the multicast packet to an optimal forwarding destination on the network to which the mobile node to join the multicast communication is connected based on the session information data.
A mobile node, comprising:
- a position registration request part configured to set one of multicast join request information and multicast leave request information in a position registration request, and transmit the position registration request to a network.
