Abstract
A method, medium, and system for reserving resources in a mobile network. A mobile node reports a start of a handover to a present access router if the handover of the mobile node occurs, and the previous access router transmits specified session information to a candidate access router that has a possibility handling the mobile node's handover. A candidate crossover router, which performs a resource reservation work on a new path and a resource release on the previous path, is searched, and a localized resource reservation is established by exchanging a specified resource reservation message before the handover is completed if the candidate crossover router is determined. Accordingly, duplication of resources can be prevented, and a prompt resource reservation can be achieved during the handover.
