ABSTRACT

Next-generation cellular wireless mobile networks based on code division multipleaccess (CDMA) technology will support different types of data services along with traditional voice service. These data services can be either elastic or inelastic. For inelastic service, the transmission rate is fixed (which is suitable for constant-bit-rate [CBR] applications), while for elastic data service, the transmission rate of the ongoing calls can be adjusted, for example, to serve more users. The call-level quality of service (QoS) for the different types of services is generally measured by new call blocking and handoff call dropping probabilities. Also, the average transmission rate is an important QoS metric for calls under the elastic service class. These performance measures need to be optimized in a CDMA cellular wireless mobile network.
