The rapid growth of 4G network give more wireless services to many users at a time in network. Many services are providing by service providers but it can face many problems in network like traffic congestion, call dropping and call blocking during handover process. In this paper, we are introducing a spectrum allocation in 4G network, which can reserve some amount spectrum from the network resource. By using adaptive CAC is reserved spectrum resource are allocated for handoff calls and new calls during users handover. It used to regulate the traffic, improved QoS, efficient spectrum efficiency and reduce spectrum degradation. The results are shown in numerical result and analytical study that the adaptive call admission control is guarantee the allocation of spectrum is used to regulate the calls by providing efficient QoS in the network resources.
