Abstract

Recently, Long-Term Evolution or LTE for 3G has been introduced to improve service provisioning for mobile network subscribers. This service improvement includes improvements in setup delay and data rates in different services. In this paper, one of the existing architectures, proposed for LTE, is evaluated. Then, probable faults in this architecture and their impacts on network services are investigated through a causality graph. This graph is used to calculate service failure probabilities in mobile networks. Also, the impact of failure of one of the serving nodes in the LTE architecture is evaluated through an analytical model. Simulation results support the arguments of the paper.
