Summary: 
To overcome the mobility impact on RSVP, many schemes have been proposed based on Mobile IP regional registration and passive reservation in advance. Although the regional registration and in advance reservation reduce the QoS interruption time, the latter may demand intolerable bandwidth. This letter introduces a novel approach to reduce the QoS interruption time by maximizing the localization of QoS re-establishment in the regional registration environment. The proposed scheme identifies the exact path segment affected by mobility. The QoS interruption time of the proposed scheme is comparable to its low bound without in advance reservation.
