To achieve end-to-end quality guarantee in regard to communication with a mobile terminal (node) in a carrier network in which Mobile IP is presupposed, in an IP network, quality guarantee is realized by performing network resource reservation in a resource reservation server receiving a resource reservation request from a node. The resource reservation server receives the resource reservation request, and decides whether the node initiating the resource reservation request is a mobile node. When the above resource reservation request is initiated from the mobile node, resource reservation is performed for the route between the mobile node and the correspondent node via a mobility management server having a home address of the mobile node.
