ABSTRACT



Cellular technologies are continuously growing and for that 3G mobile technology has been implemented i.e. Universal telecommunication Mobile System (UMTS). In UMTS, services are categorized into four UMTS client application classes. The main issue is achieving mobility in implementing the 3G protocol. The soft handover supports the continuous service although a user equipment start moving from one's base station to the another base station or even from one's cell to the another cell and supports the seamless handover. In this paper the soft handover scenario is implemented using OPNET 14.5. Their performance evaluation is done by compare with two scenarios in it, one of with low traffic & one with high traffic load, and performing the random trajectory on them, one with 4 UE and another one with 9 UE. Performing the simulation and conclusion are compiled on an interval of 4 min. Various parameters of the soft handover are considered here as total number of cells added & removed, ATM load, total throughput (pkts/sec), active cell count, end to end delay (sec)
