A light-weight, dynamic call admission control for sudden user influx management

Occasional user influx in a cell in a public place like a football stadium congests the network and even leads towards total disruption of services. However, for this temporary high user concentration, the service providers would not be interested in maintaining a huge infrastructure. This demands an efficient, provisional capacity enhancement technique without any additional infrastructure towards increasing service accessibility to maximum number of users. In this paper, an attempt has been made to propose a light weight call admission algorithm for increasing the number of admitted call in this type of constrained scenario. The proposed algorithm is supposed to work satisfactory for a GSM standard telephone network in terms of adaptability, number of admitted customer and the involved cost overhead.
