INAP stands for "Intelligent Network Application Part." It is a standardized protocol used in telecommunications networks that enables the communication and exchange of information between different network components and applications.
INAP is a vital part of intelligent network (IN) architecture, which allows advanced services such as call routing, prepaid services, and advanced subscriber management. It facilitates the interaction between service-independent and service-dependent components in the network, ensuring seamless exchange of data.
This protocol serves as an interface between the signaling system and the service control function in the IN. It enables the signaling system to carry information related to call handling, service negotiation, and other service-specific parameters. INAP messages are processed by the service control point (SCP) and trigger specific intelligent network service logic accordingly.
INAP is based on the Common Channel signaling (CCS) protocol and typically operates over Signaling System No. 7 (SS7) networks. It supports a wide range of services, including both voice and data services. By allowing service control functions to be separated from the switch, INAP enables flexible and scalable service creation and deployment.
With the help of INAP, telecommunications networks can offer advanced and personalized services to their subscribers, increasing revenue opportunities and customer satisfaction. It plays a crucial role in the efficient functioning and management of intelligent networks, driving the evolution of modern telecommunications systems.
