Effect of softhandover function on effectivity of using radio sources in UMTS
 Plhák, Jan ; Lambertová, Petra (referee) ; Novotný, Vít (advisor)
Bachelor’s thesis is focused on soft handover procedure in the UMTS network and its impact on the function of this network. Soft handover function allows continuous transfer of data flows, when the mobile station is crossing the border between areas which are controlled by different basic stations. This function has also impact on the performance and capacity of the whole network. This thesis describes the features of the UMTS network, soft handover principles, differences between various types of handovers and focuses on the mechanisms of the soft handover in detail. There have been several scenarios of handover procedure created in network simulation software and have been confirmed features of this function, that allows use of the lower transmission powers. On the other hand the soft handover burdens radio resources more than hard handover because of multipath propagation of the signal. To achieve the greatest soft handover gain, parameters of the network have to be set properly.
