Intelligent Network (IN) architecture in telecommunications refers to a framework that allows the integration of advanced and intelligent services into the traditional telecommunication network. The purpose of the Intelligent Network is to enable the creation, provision, and management of value-added services in a flexible and programmable manner. This architecture allows service providers to deploy and control services independently from the underlying network infrastructure.
Key Aspects of Intelligent Network Architecture in Telecom:
- Separation of Service Logic and Switching Equipment:
- One fundamental principle of Intelligent Network architecture is the separation of service logic from the switching equipment. This separation enables service providers to introduce and modify services without making changes to the core network elements.
- Service Control Points (SCPs):
- The Intelligent Network includes Service Control Points (SCPs), which are dedicated databases or servers responsible for storing the service logic and control information. SCPs act as intelligent service controllers that execute service logic based on predefined rules.
- Service Switching Points (SSPs):
- Service Switching Points (SSPs) are network elements responsible for the actual call handling and switching functions. They interact with SCPs to obtain the necessary service logic and instructions for processing calls. SSPs are typically located in the central office or switching centers.
- Intelligent Peripherals (IPs):
- Intelligent Peripherals (IPs) are specialized devices or components that provide additional functionality to the Intelligent Network. They can include elements like voice response units, announcement servers, or media gateways, enhancing the capabilities of intelligent services.
- Service Creation Environment (SCE):
- The Service Creation Environment (SCE) is a set of tools and interfaces that allow service providers to design, create, and modify intelligent services. It provides a platform for developers to define service logic and specify how services should interact with the network.
- Common Channel Signaling (CCS):
- Intelligent Network architecture often utilizes Common Channel Signaling (CCS) protocols, such as Signaling System No. 7 (SS7), for communication between network elements. This signaling approach separates signaling information from voice or data traffic, facilitating the exchange of control messages between SSPs and SCPs.
- Dynamic Service Invocation:
- Intelligent Network supports dynamic service invocation, allowing services to be invoked or modified in real-time based on the specific conditions of a call. This flexibility enables the implementation of personalized and context-aware services.
- Flexibility and Scalability:
- IN architecture is designed to be flexible and scalable, allowing service providers to introduce new services without significant changes to the existing network infrastructure. This adaptability is crucial for keeping pace with evolving consumer demands and technological advancements.
- Network Management and Billing Integration:
- The Intelligent Network integrates with network management systems and billing platforms to ensure efficient operation and monetization of services. Network operators can monitor, analyze, and optimize the performance of intelligent services while accurately billing subscribers.
- Support for Advanced Services:
- Intelligent Network architecture supports a wide range of advanced services, including call forwarding, call waiting, voice messaging, and interactive voice response (IVR) systems. It serves as a foundation for deploying innovative and revenue-generating services.
- Evolution to Next-Generation Networks:
- The concepts and principles of Intelligent Network architecture have influenced the evolution to next-generation networks, including IP-based networks and the introduction of services in converged and multimedia environments.
In summary, Intelligent Network architecture in telecommunications provides a framework for integrating and delivering advanced, value-added services in a flexible and programmable manner. The separation of service logic from network infrastructure, along with the use of SCPs, SSPs, IPs, and a Service Creation Environment, allows for dynamic service invocation and the efficient deployment of innovative services.
