INAP - Intelligent Network Application Part


The INAP stands for Intelligent Network Application Part. It allows for the implementation of carrier-grade, signaling infrastructure targeted to the world wide fixed telephony market. It is a signaling protocol between a service switching point (SSP), network media resources and a centralized network database called a service control point (SCP). The SCP consists of operator or 3rd party derived service logic programs and data. Through INAP, operators have gained independence from the software features offered by switch vendors. With intelligent network, operators are able to implement value added services giving them competitive advantages in the market.
Services that can be defined with INAP include:
  • Single number service: one number reaches a local number associated with the service
  • Personal access service: provide end user management of incoming calls
  • Disaster recovery service: define backup call destinations in case of disaster
  • Do not disturb service: call forward
  • Virtual private network short digit extension dialing service
Following are some short descriptions on relevant terms.
Service Switching Point (SSP) is a physical entity in the Intelligent Network that provides the switching functionality. SSP is also the point of subscription for the service user.
Service Control Point (SCP) authenticates information from the service user, processing requests from the SSP and issuing responses.
Intelligent Peripheral (IP) provides resources. These may include customized and concatenated voice announcements, voice recognition, and contains switching matrix to connect users to these resources.
Service Management Point (SMP) performs service management control, service provision control, and service deployment control.
