The Network Processor • produces network-wide results out of the single- cell-based results
• allows to analyse the radio network BS1 • allows to simulate changes of the network parameter BS2 • allows to simulate changes of the network design BS3 • allows to optimise the radio network • allows to plan the future roll-out phases • produces statistics on the selected results BS3 BS2 BS1 each Service needs an own service-specific Network Processor
