SSCF Service specific co-ordination function

Last updated on 


The Service Specific Coordination Function (SSCF) is a component within the Signaling System 7 (SS7) protocol suite that is used in telecommunication networks for call and service handling. The purpose of the SSCF is to coordinate and manage the delivery of services between network elements.

In SS7, the network is divided into multiple levels known as Signaling Points (SP). Each SP is responsible for specific tasks related to call and service handling. The SSCF operates at the higher levels of the SS7 protocol stack, typically at the level of Signaling Transfer Points (STP) or Service Switching Points (SSP).

The main functions of the SSCF include:

  1. Service Control: The SSCF is responsible for controlling the delivery of services within the network. It receives service requests from the Service Switching Function (SSF) and determines how the request should be processed and routed. It ensures that the requested service is delivered to the appropriate destination.
  2. Message Distribution: The SSCF distributes signaling messages between the various network elements involved in delivering a service. It receives messages from the originating SSP or STP and forwards them to the appropriate destination SSP or STP based on routing information.
  3. Protocol Conversion: The SSCF performs protocol conversion between different signaling protocols used within the network. It translates the signaling messages between the SS7 protocol and other protocols such as ISDN (Integrated Services Digital Network) or IP (Internet Protocol). This enables interoperability between different network elements that may use different signaling protocols.
  4. Service Interaction: The SSCF handles interactions between different services within the network. It ensures that services can interact with each other seamlessly by coordinating the exchange of signaling messages. For example, if a call involves multiple services such as call forwarding and call waiting, the SSCF manages the interactions between these services to provide the desired functionality to the end user.
  5. Service Activation/Deactivation: The SSCF handles the activation and deactivation of services within the network. It receives requests for service activation or deactivation from the SSP or STP and performs the necessary actions to enable or disable the requested service.

Overall, the SSCF plays a crucial role in managing the delivery of services within a telecommunication network. It provides coordination, control, and protocol conversion functions to ensure efficient and reliable service handling. By performing these tasks, the SSCF contributes to the smooth operation of the network and the delivery of high-quality services to end users.
