• Increase of Call Processing Performance by factor 5
• Enough Performance for more than 1 million subscriber MSC => enough
capacity until 2010
• Evolution of proven CP concept: same superior quality and well known
3. Benefits of PowerCP3. Benefits of PowerCP
28 Introduction to Siemens Mobile Networks
• Seamless integration into existing platform due to compatible interfaces -
only partial HW replacement necessary
• One APS supports PowerCP (CP113E) and CP113C without further
modifications
• Solutions of other providers are based on complete new HW: this requires
severe SW modifications and a new stabilization phase.
