This work introduces a new analytical method for perfor- mance evaluation of wireless packet-oriented networks. Unlike traditional call admission control procedures commonly used for performance evalu- ation of wireless networks, this paper deals with the problem of coupling connection and packet level QoS characteristics by analysis. At connec- tion level we use the Blocked-Calls-Cleared (BCC) model, whereas at packet level we use the Blocked-Call-Interfered (BCI) model which has no immediate feedback from packet level to connection level about lost data. At connection level we use the convolution algorithm which de- fines the feasible state space at packet level. At packet level we take into consideration wireless interference (soft blocking). The traffic is modeled as multi-rate Binomial-Poisson-Pascal (BPP-) traffic at connection level and on-off traffic at packet level. We obtain individual performance mea- sures for each service, both at connection level and at packet level. By case studies we investigate the trade-off between the two levels to meet Grade of Service (GoS) requirements for cellular networks with WCDMA radio interface.
