Abstract

The rapidly growing mobile demands have reinforced the network providers to emphasize on the basic customer needs and the resource management. The two main areas such as capacity management and data service provisions have engulfed the research field. This research paper attempts to cover both these issues in terms of Call Admission Control (CAC). Paper presents an adaptive technique built upon our previous static CAC research. The scheme provides differentiated admission to various delay sensitive (DS) and delay tolerant (DT) traffic streams for both Handover Request (HOR) and New call Request (NCR) according to current load intensity. It is based on an effective pre-emption priority in order to reduce the forced handover failure probability. Service nature and customer behaviour have been considered to lay down the different levels of priorities that were assigned at different stages of CAC Scheme in order to achieve optimal quality of service (QoS) for urban area (metropolitan) cell.
