Automatically Optimization Technique Using A DNCL To Avoid Dropped Calls In Cellular Network

Abstract: Dropped calls can be avoided in cellular networks by an Automatically Optimization algorithm. An optimization technique have been generated using a DNCL (Dynamic Neighbor cell listing), which uses an automatically optimization algorithm to avoid call drop in cellular networks. In cellular networks the Dynamic Neighbor cell list (DNCL) has an important impact on the number of dropped calls and is traditionally optimized manually with the help of planning tools. We have used a method which automatically optimizes DNCL, which consists of a self configuration phase for initialization, followed by a self-optimization phase which further refines the DNCL based on measurements provided by mobile stations during the network operation. The proposed method performance is evaluated for different user speeds and different DNCL sizes. Besides, the convergence speed of the proposed self-optimization method is evaluated. It is shown that automatically optimization method reached a stable maximum performance about 99% of success rate when about 6000 measurements are reported by mobile stations.
