Mobility Based Call Admission Control for CDMA System Supporting Integrated Voice / Data
N. Tamilarasan, P. Dananjayan, K. Jayanthi · 2007
A CAC (call admission control) schemes is effectively regulate the traffic load of a network such that uninterrupted service is provisioned to every admitted user without over penalising the new admission requests. This task can be accomplished by properly managing the available network resource power in an optimum way. In CDMA (code division multiple access) system, capacity is limited but the total interference power at each base station, which dynamically changes with time. Thus, the total power received from the system is a useful indicator of traffic load. In this work, an algorithm is proposed to accurately estimate the updated received power due to new calls based on the periodical measure of the received power. Using the proposed logic, it is possible to maximize the resource utilization and as well guarantee minimum blocking rates.
