The integrated architecture of AIN SSP

The service switching point (SSP) is one of the primary elements for advanced intelligent network and an access point to the AIN services. The paper describes the integrated software architecture of AIN SSP based on the TDX-10A exchange that is operated as a toll and tandem switching system by Korea Telecom (KT). This paper also presents AIN structure, the system architecture, the integrated software architecture, and the AIN service performance.
