An Investigation of CAC in UMTS Cellular Networks

  • Author(s) / Creator(s)
  • The successful deployment of UMTS (Universal Mobile Telecommunication System) Cellular Network is heavily dependent on CAC (Call Admission Control) which plays a major role in ensuring QoS (Quality of Service) to be achieved. This report is based on the investigation of CAC (Call Admission Control) including the different parameters of RNC (Radio Network Control) Admission Control such as uplink and downlink loading factors, Scheduling Weights, and some attributes of Node-B (Base Station) like Resource Allocation/Retention Priority. Also evaluates the performance of CAC by using the
    OPNETTM Modeler ver11.5 based on the self made simulation models. And construct the Static Scenario by considering the two QoS traffic classes; streaming and Background. And analyze the relation between offered load and throughput.
