Joint Connection and Packet Level Analysis in W-CDMA Radio Interface [chapter]

Vilius Benetis, Larissa Popova, Villy Bæk Iversen
Wireless Systems and Mobility in Next Generation Internet  
We obtain individual performance measures 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.  ...  New-call blocking probabilities, handover-call dropping probabilities, and packet losses are calculated in [5] based on a joint connection and packet-level QoS.  ...
