Experimental Comparison of UMTS and Beyond Architecture Evolution Scenarios
01 January 2004
Current standardization activities of 3rd Generation Partnership Project (3GPP) Release 6 (R6) working groups show that hierarchical UMTS R3 networks influenced by GSM and ISDN history are changing towards decentralized and distributed network architectures based on IP principles. Equipment manufacturers already submitted various proposals for UMTS R6. Subsequently 3GPP ordered a feasibility study and requested an evaluation of the different architecture proposals with regard to performance. In this paper we present a simulation modeling approach built within OPNET which provides an environment for an easy assessment of different evolution scenarios of the UMTS architecture with regard to signaling performance.
