Abstract

In this paper we analyze the performance of a voice handover scheme for Long Term Evolution (LTE) and Universal Mobile Telecommunications System (UMTS) networks. Single Radio Voice Call Continuity (SRVCC) is deemed to be the long-term solution for LTE and UMTS voice handover. The scheme is modeled on handover signal flows. The analysis is done using a Radio Link Control (RLC) Protocol model, a network node queuing model and a remote network model. The simulation of the handover performance was on these three models. The simulation results were analyzed and compared with Third Generation Partnership Project (3GPP) specifications.
