Abstract [en]

Nowadays a very important aspect of telecommunication is quality of services. 3G networks offer all of the customers’ best quality for each type of information including voice/video and data transmission. One of the vast discussion in this area is increasing the throughput and prevent the congestion in rush traffic hours in the network. Congestion occurs when transfer rate in the network is lower than requested rate by application. Congestion leads to cell loss and dropped cells should be retransferred to recover the data which is double job and affect the throughput and even can affect the quality of the services. Time sensitive information (voice/video) requires no data loss and they employ Forward Error Correction (FEC) codes to recover the data. The number of the FEC codes should be kept small to prevent the overload in the network. In this paper I will show that just simple FEC is not enough when network interworks with Asynchronous Transfer Mode (ATM). A powerful buffer management gives higher throughput and in that condition block loss rates reduces. In addition, effective utilization of IuB interfaces that link the Radio Network Controller (RNC) and Base Station (BS) has another effect on throughput. Different service categories are used to transform different type of information. In this paper we have also introduced all kind of information types offered by 3G networks and further analyzed the weakness of the existing transmission phase in 3G networks.
