In our thesis, our main objective is to explore some RRM strategies and understand their practical importance by simulating some RRM algorithms. 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….
