Abstract


This research work is regarding the simulation based analysis of handover issues affecting the UMTS network performance. The mobility is provided by handover to user which is the major subject matter of wireless communication and handover provides the interpretability between different network technologies. However handover is an issue that is focused here, to know the parameters which cause to degrade the UMTS network performance. A radio link disconnection problem occurs when a User Equipment moves from one cell to another. In this study, the interactive and conversational traffic parameters are analyzed by simulation. To accomplish the task of simulation and analysis, OPNET Modeler 14.5 and Matlab are used. It is established through results that Soft handover is better than hard handover because soft handover reduces near far effect; it maintains the connection during handover.
