A Call Admission Control Scheme for Cellular Network to Handle Sudden Influx in a Confined Area

Abstract

Call Admission Control (CAC) is a typical problem in cellular network and needs more attention for up-gradation of the existing ones. The challenge is to allow more calls without disturbing the quality of service through efficient bandwidth distribution amongst cells. Several statistical approaches are used to guess the channel requirements in near future and re-distribute the bandwidths in each cell accordingly. But all these proposed method fails, if there is a sudden influx of user’s concentration in a confined area and that is happening frequently in a real scenario like in an auditorium or in a football ground. The intention of a service provider is to increase the number of allowable calls that are not being permitted by the existing schemes and thus demands a new mechanism to adapt this unpredictable situation. In this paper, a policy is proposed to manage huge data traffic within a confined area network with higher user concentration. Here the users are being prioritized based on some proposed metrics and the scheme is allowing more calls according to the priority of the competing users. The proposed concept is being implemented and also compared with an existing widely accepted scheme. The offered solution is expected to perform better than the existing CAC schemes for the above mentioned situation.
