SCP
The Service Control Point (SCP) is the core component of the traditional
intelligent
It provides the following functions:
1)
2)
Send call control instructions to the related SSP to control its next action.
Implement the intelligent calls.
II. Network control layer
The network control layer implements call control. It uses softswitch as core
technology to implement basic real-time call control and connection control.
As shown in Figure 1-1, the SoftX3000 SoftSwitch is the core device in the NGN. It
implements the following functions:
1) Call control
2) Media gateway access control
3) Resource allocation
4) Protocol processing
5) Routing
6) Authentication
7) Charging
8) Provides basic voice services, mobile services, multimedia services, and APIs.
III. Core switching layer
The core switching layer adopts the packet technology. It is composed of the devices
like routers and layer-3 switches in the backbone network and the metropolitan area
network (MAN). It provides subscribers with a unified and integrated transmission
platform with high reliability, quality of service (QoS) assurance and a large capacity.
