Network Landscape
• Phase 1: Coexistence of all networks ( the coming ten
years)
– PSTN/NGN/3G coexist;
– Multi-network service convergence to provide integrated access
under “one number” ;
– From the subscriber’s point of view, services are offered by an
integrated multi service network.
• Phase 2: Integrated multi-service network (ultimate
network)
– The ultimate goal of NGN: Deliver combined voice, data, video,
and 3G over a single network.
—— Report on Annual NGN Summit 2004

Success Stories --China Satcom
 Background
 Founded in Dec. 2001, China Satcom is one of China’s six top
operators. It is licensed to provide C4 telecom services. As a new
player for fixed networks, its main resource is satellite
communication network resources.
 After careful technology analysis and validation, Satcom finally
decided on NGN to construct their network.
 Vision
Building brand of first national commercial NGN in China.
Building brand of “unified sky and land” in China.

Benefits
•
Cost savings: both problems of intelligent PSTN and provisioning of NGN
services are addressed;
•
Service experience: implement network-wide service provisioning without
investing in existing LSs;
•
Local CDR: local CDRs are provided by the transit offices. There is no need
to upgrade or reconstruct LSs;
•
Optimized network structure: target structure reducing overall network cost
•
and handling the problem of large numbers of small LSs;
Simplified maintenance and routing of LSs: consequent human power savings,
reduced requirement for LS maintenance technicians, and better support for
centralized maintenance.
