Softswitch Deployment in
China Mobile
• Step1: Long-distance tandem softswitch
– Replacement to Class-4 trunking switches
• Step2: 3G R4 CS domain
– Replacement to Class-5 circuit-switch MSCs
• Step3: IMS-based NGN
– All IP
– Multimedia
– Access-Irrelevant
Step by step!
Softswitch long-distance tandem
network of China Mobile
• On November 27, 2004, China Mobile completed the cut-off of
the Softswitch network, the ever largest one in the world;
• The network is expected to carry 17951 provincial internetwork traffic across 31 provinces in China, with the total
traffic equivalent to one-third of the traditional provincial
network traffic.
• On the eve of Spring Festival, the traffic is 3 times higher than
the average traffic. In such peak traffic, the network shows
outstanding performance.
• The commercial application of the Softswitch long-distance
tandem network of China Mobile proves the possibility of
building a network with Softswitch technology.

IPI (IP Interworking)
• A GSMA project
• Service layer Interworking for IMS based
IP networks
– Service control
– Service based charging and balancing
• China Mobile is leading IPI trial in Asia
• IPI trial in Europe has completed
Our Proposals
• Further study on IMS-based NGN,
including its application scenarios and
deployment strategy in different countries.
• Push IMS to maturity and commercial use.
• Promote inter-working test of IMS.
Thank You!
