3G mobile communication systems launched after some hardware and software changes on existing systems. After these changes operators have new services for subscribers. In this thesis, our target is to find problems, which faced by subscribers, with field measurements. Along these field measurements there were drop, congestion, and low data rate problems. After analyzing these problems we did some hardware and software changes. In this thesis you will find information about these hardware and software changes and the result graphs, which contains comparison for before and after these changes. These results verified by verification tests, if needed the problems re-analyzed and tried to optimize the system.
