| Abstract The aim of this paper is to analysis and optimizes the efficiency of the Enhanced Data rates for GSM Evolution (EDGE) Quality of Service (QoS) profilewhich is used for Packet Data Protocol (PDP) context in data transfer over GSM/EDGE networks.Two software tools were used in the practical part: the first one is a Subscriber Management Unit client (SMU/9820) from HUAWEI Technologies Co., Ltd. that is a real time system for mobile network management in HUAWEI Home Location Register (HLR); the second is a DUMETER 5.02, which monitors the network traffic and displays a real time charts. The practical part has been achieved in Asia cell telecommunications Company in three different cities; Mosul, Duhok and Erbil: each one in three levels; the first level is the analysis of available QoS in the network, based on the default profile which depended by the network. However, 24 testing have been recorded; this testing has been repeated for three cities. In second level a hundreds of tests and optimization implemented on tens of QoS and PDP parameters in order to reach better data rate. Final level includes the implementation of the proposed profileswhich resulted from second level. Finally, the proposal profiles improved the performance of the QoS which reflected the gains of 34% in average data rate in the three cities. Keywords: HLR, GSM, QOS, ED | ||
