Link and network layer requirements for mobility support in CDMA wireless systems

Code division multiple access (CDMA) is an interference limited multiple access technology. The signal-to-interference (SIR) ratio, in the form of E-b/I-o, is an important parameter in CDMA systems and has a profound effect on the system capacity and utilization. They in turn affect the network level QoS in terms of new call blocking probability and forced termination probability. A relationship between the link layer E-b/I-o specification and the network layer QoS parameters in the presence of user mobility is established. Numerical results which display the linkages between the link layer and network layer QoS parameters are presented and discussed.
