I have developed a tool that can be used to dimension the base station / Node B for a multi-service scenario. It is possible dimension a case with simultaneous traffic of:
Voice
Circuit data 64 kbps
Circuit data 128 kbps
Packet data 64 kpbs
Packet data 384 kbps
The service share a common pool a channel elements. Blocking rate and throughput/delay targets are considered by the tool.
