Abstract
Cellular operators are facing difficulties in supporting a huge increment in the subscribers due to spectrum and equipment restrictions. Substantial amount of investigation has been reported in the area of increasing call carrying capacity such as Reuse Partitioning and Directed Retry. However, such action increases the size of the network and results to higher installation, maintenance and optimization costs for the cellular operator. In this paper, a cost effective new channel reservation scheme based on subscribers’ average call duration has been reported. A cell has been considered which has very few allocated channels and is also unable to execute load balancing methods such as channel borrowing, call transfer etc. A cell with such restrictions may have higher blocking probability during busy hours, but the results show that the proposed scheme can effectively reduce the overall call-blocking for such cell. The resulted scheme is particularly useful in a cell having heavy traffic with mostly business calls.Reference
