Abstract
— Mobile applications for multimedia services such as video conferencing, file downloading and web browsing etc. over the network have high demands in terms of available network resources and Quality of Service (QoS) performances. The importance of QoS provisioning has become one of the central issues of 3G mobile network design and analysis. Now a day’s, tere is a need to achieve mobility and continuous service is achieved by supporting handover from one cell to another. It is regularly initiate either by crossing a cell boundary or by deterioration in quality of the signal in the current channel. Handover is a key concept to achieving mobility. Handover stands for event which is start when user equipment moving to another base station and leave the previous base station. It makes possible for a user to travel from one cell to another, with no interrupt is known as seamless connection. In this paper, implementation of soft handover is made using OPNET MODELER.5 user equipment perform soft handover in logical network under soft limits of soft handover criteria. The performance of soft handover is test under characteristics of GPRS attach delay, CBR delay (sec), active cell size, cell added to the set and cell removed from the set.
