In cellular networks, call admission control (CAC) has a direct impact on quality of service(QoS) for individual connections which in turn affects overall system efficiency. Traditional reservation based schemes are not efficient for handoff  rates, as the reserved bandwidth may not be utilized effectively in low hand-off rates. Therefore, we propose channel borrowing approach in which new calls can reserve bandwidth depending on its priority. Later, if handoff calls arrives and all the channels are busy, it will pre-empt the service of a borrower call if there exists. In addition the focus is also to reduce the call dropping probability(CDP) and increase the total system capacity and performance; Hence the QoS of the system can significantly be improved especially in high mobility environment.
