Resource reservation system and method in wireless network

摘要

A resource reservation system and a method for managing resources under consideration of the mobility of an MN are provided where an old refresh interval for an old resource reservation state is changed in response to handoff. The changed refresh interval propagates through at least one of a path supporting a corresponding session before the handoff and a path newly established due to handoff occurrence. When the handoff is completed, resources are released on a path, which is a part of the path supporting the corresponding session before the handoff and is not used due to the handoff occurrence, based on the changed refresh interval.
