The handoff call blocking probability minimization is an important issue for seamless wireless network operation. Handoff delay minimization is in parallel with this task. Mobile stations with QoS requirements should be able to receive the same service level during and after handoff. This constraint amplifies the handoff latency caused forced termination problem. This research introduces a handoff method, which performs some preparation phase tasks in advance, in wireless networks. With the Expected Visitor List (EVL) deployment at base stations and RSVP, QoS requirements of an incoming mobile station is obtained and examined, and hence overall handoff latency minimization is achieved A virtual QoS provisioning method for call admission control of the mobile is also proposed Performance evaluation with simulation experiments shows that the proposal can be a promising methodology for QoS provisioning in the Next Generation (NG) wireless networks.
