intelligent network conceptional model (IN) (INCM)

The conceptual layer model for intelligent networks( IN) standardized by the ITU-T and the European Telecommunications Standards Institute ( ETSI) ETSI, the Intelligent Network Conceptional Model (INCM), consists of four different layers. These four layers include the physical aspects, the function distribution, the global functionality and the service aspects.

The four layers of the IN layer model

The Physical Plane( PP) contains the elements used at this level and their interfaces that implement functional entities. This layer includes the Service Switching Point( SSP), Service Control Point ( SCP), Service Management Point ( SMP), Service Creation Environment Point ( SCEP), Service Management Access Point ( SMAP), Customer Service Control( CSC), and the Intelligent Network Application Protocol ( INAP).

In concept, an intelligent network is centrally organized. The service control points (SCP) act as the control center for the services in the IN. With the support of central databases, they handle the traffic management for the IN connections and the administration of charging and statistical data. In the process, the Service Management Point (SMP) takes over the data for the purpose of configuration and service management. When an IN service is used, the request is detected by the Service Switching Point (SSP) and processed by the SCP point.

The second layer of the IN architecture is where function distribution takes place. Here, the Distributed Functional Plane( DFP) models the distribution of IN functionality across multiple logical entities. Components of the Distributed Functional Plane are the Functional Entity Actions (FEA) and the Service Logic Programs( SLP). The third level on which the intelligent network is represented as a single entity is the Global Functional Plane( GFP). It is used by service designers to integrate services using the Service Independent Building Blocks( SIB).

Thanks to this concept, services can be defined via a simple description using the Service Plane( SP), which is the upper layer of the IN functional layer model. The service plane is service-oriented. The services provided on the SP layer consist of the Service Features( SF), which are service characteristics.
