Abstract: A communication method is capable of preventing an occurrence a change of a route for an underway communication between a mobile node and a correspondent node in a communication network and restraining an unnecessary packet from being forwarded to the correspondent node from the mobile node. The communication method is executed among the mobile node having a home address assigned in a first network and a temporary address assigned in a second network, an agent device surrogating a communication using the home address in the first network and a correspondent terminal communicating with the mobile node through the agent device. When the mobile node moves to the second network, the mobile node transmits information containing the temporary address to the correspondent node, and the correspondent node receives the information containing the temporary address and transmits the information to the temporary address of the mobile node.
