Universal Mobile Telecommunication System (UMTS) is a third generation mobile communication system, designed to support a wide range of applications with different quality of service (QoS) profiles. This 3G system has capability of transporting wideband and high bit rate multimedia services along with traditional cellular telephony services e.g voice, messaging etc. To provide these services with better quality of service and enhance the performance of wireless network, management of radio resources is necessary. To do this, UMTS offer many radio resource management (RRM) strategies. These RRM techniques play important role in providing different services with better quality, keep the end user happy and make the network stable. In our thesis, our main objective is to explore some RRM strategies and understand their practical importance by simulating some RRM algorithms. First we start with UMTS overview and learn some important concept about UMTS architecture. Then we go deep into physical layer of UMTS. After getting strong concept of UMTS radio architecture and procedures, we worked on different RRM techniques and in the end we analyze two power control algorithms to understand and get some practical experience of actual RRM strategies...
