Dynamic Channel Allocation Scheme for Handover Calls in Cellular Networks

Abstract

Prioritizing handover calls is an important process in cellular networks. The blocking/dropping calls occurred when there is no free channel is assigned for the subscriber. So, we are going to devise a new scheme for handling the calls among the network. In this paper, the main idea is to maintain an acceptable blocking/dropping trade-off probability for the indoor cells. The proposed solution will show how to change dynamically the number of reserved channels and optimizing it based on the incoming offered traffic type (new or handover calls). The Guard Channel and Non-Prioritized schemes are considered. Finally, the results reveal that call blocking and dropping probabilities performs better while compared with the other existing scheme.
