Publisher Summary This chapter reviews the mobile radio access network reference scenarios (MORANS)—used to study the performance of the radio cellular networks related to UMTS and the methodologies for the radio network performance evaluation, including the theoretical connectivity models,. It discusses the techniques for radio network optimization such as the packet scheduling for cellular systems or system capacity maximization through the use of multiple antennas. . In order to perform system simulations, reference values for the main parameters characterizing a WCDMA network, are required. MORANS is used for the identification of such parameters. The parameters are classified in two groups: the parameters whose value can be found in the specification documents, and the parameters with unspecified value requiring optimization. The estimated performance in the downlink of a WCDMA network can be evaluated by means of two dynamic system simulators. The chapter concludes by discussing important RRM procedures, simplified algorithms. Some of them are: call admission control, congestion control, and soft handover procedure.
