Abstract	To support network-wide handoff, new and handoff call requests will compete for connection resources in both the mobile and backbone networks. Handoff calls require a higher congestion related performance, i.e., blocking probability, relative to new calls because forced terminations of ongoing calls due to hand-off call blocking are generally more objectionable then new call blocking from the subscriber's perspective. A hybrid scheme has been proposed for handover in ATM-based PCN, which combines queuing and reservation schemes. In the scheme, FIFO and measurement based priority scheme (MBPS) queuing discipline (S. Tekinay and B. Jabbari, 1992) and reserved channel scheme (RCS) (Y.C. Kim et al., 1999) is used. This scheme gives handovers higher priority than queuing or reservation schemes. When reservation is applied on both radio and backbone channels, it leads to significant improvement in quality of service (QoS) parameters. After applying proposed scheme there is a remarkable reduction in forced termination probability (FTP) at the cost of tolerable call blocking probability (CBP)
