🟢SSP - Service Switching Point
SSP - Service Switching Point
A Service Switching Point (SSP) is a component of the Intelligent Network (IN) architecture.
It is an advanced telephone exchange (switch) that detects specific call events and interacts with Service Control Points (SCPs) to process special services based on predefined criteria.
The SSP plays a crucial role in providing enhanced telecommunication services by enabling dynamic call handling and routing.
Functions of SSP
Call Event Detection: The SSP monitors the call setup process and identifies specific triggers that signal the need for specialized processing, such as dialing a toll-free number or requesting a collect call.
Communication with SCPs: When a trigger condition is met, the SSP communicates with Service Control Points to retrieve instructions on how to handle the call. This might involve querying databases or executing service logic stored in SCPs.
Dynamic Call Routing: Based on the instructions received from SCPs, the SSP can modify the call path dynamically. This might include redirecting calls based on user preferences, call types, or time schedules.
Service Logic Execution: The SSP can execute predefined service logic to provide various telecommunications services such as call forwarding, conference calling, or call screening.
Data Collection: Collects and reports data required for billing and analytics purposes, capturing necessary call details to ensure accurate billing and service metrics.
Importance in Telecommunications
SSPs enhance the flexibility and functionality of telecommunication networks by allowing real-time decision-making and service customization.
This adaptability helps in efficiently deploying new services without the need for exhaustive hardware upgrades.
