Abstract
A QoS setup method comprises the steps of a mobile node MN recognizing a first QoS setup request when an opposite correspondent node CN makes the first QoS setup request for its route to the home address HoA of the mobile node MN, the mobile node MN making a second QoS setup request, and establishing the second QoS setup for a route between the home address HoA and Care-of Address CoA of the mobile node MN. This method makes it possible to carry out QoS setup for a section to a moved-to place of a mobile node MN in response to a QoS setup request from an opposite correspondent node CN, even if the correspondent node CN and mobile node do not have a function of route optimization.
