Handover Measurement in Mobile Cellular Networks: Analysis and Applications to LTE

This paper deals with the handover measurement in cellular networks. The work is dedicated to network modeling and performance evaluation. The exposition concentrates on temporal evolution of the scanning process with key events: (i) a suitable handover target found, (ii) call drop or service failure, and (iii) scan withdrawal. By observations on the stochastic properties of best signal quality and minimum-duration outage, we determine the probability of the key elements and provide a generalized framework for network design and analysis such as in scanning failure probability and target cell expected quality. Results obtained with LTE have also shown its effectiveness.
