Impact Signal Propagation Parameters to UMTS-LTE Handover

Handover mechanism is to maintain continues connection by migrating users from one to other channel within a base station or different ones. As wireless channel is heavily depending on signal propagation, the propagation parameters are important factors in handover decision. This papermodelsmobile node path through three base stations and analyses the propagation parameters impact on softhandover performance between UMTS and LTE networks. Simulation results on the designed model show that the greater the value of the velocity then the point of sampling that occurs will be less and the number of handover will be greater. Conversely, if the speed is lower than the sampling point that occurs will be more and the number of handover will be smaller. It is found that the speed at 10 m / s is the best speed because the RSCP (Received Signal Code Power), and RSRP(Reference Signal Received Power) signal strength values are -99 dBm and -111 dBm respectively with the number of sampling points being 57 and the number of handing over is 2 times.
