Abstract: The performance of a cellular network is centered on her ability to perform circuit and packet switch services. Improvements in these services has led to evolution of cellular network up to the 4th generation that is designed for IP and packet service. This paper presents and analyzes mobile phone behaviour and network performance of circuit services using the Circuit Switch Fall Back (CSFB) approach in LTE from various LTE cells. The goals of our study were to extend our understanding of mobile phone behaviour during CSFB by characterizing a cellular network and understand legacy fall-back preference of the mobile phone. LTE enabled mobile phones during circuit switch services falls back more on the UMTS network without much consideration on the radio environment as the UMTS has a mean fall back probability 0.77 and average fall back time of 1.56ms as against the GSM which was 0.23 and 1.86ms. The result shows that it will be difficult for the UE to successfully fall-back from a distance away from the cell and the UE power consumption rate will be very high.
Index Terms: Circuit Switch Fall-Back (CSFB), circuit Switch, Universal Mobile Telecommunication System (UMTS).
