This paper discusses the issues needed to be resolved when faced network-oriented RSVP is used in wireless mobile networks

and puts forward a scheme to extend existing RSVP in 3GPP2 framework-based wireless mobile networks. There are three main extensions: the first uses RSVP over IP tunnels to establish end-to-end active reservation

which will provide data flows with guaranteed QoS. The second uses mobility predication and passive reservation to make advanced reservation of wireless resource in a set of cells where mobile node will enter in the near future

and this extension can increase the probability of successfixl handoff. The third employs active handoff to reduce the time used for adjustment of reserved paths

and further improves the probability of seamless commumcatron.
