ITU-T Q.1228 (09/1997)

عربي | 中文 | English | Español | Français | Русский
Interface Recommendation for intelligent network Capability Set 2
Recommendation Q.1228 defines the Intelligent Network (IN) Application Protocol (INAP) for IN Capability Set 2 (IN CS-2). This Recommendation defines the INAP for IN CS-2 based upon the IN CS-1 refined (CS-1R) Q.1218 specification (1995) and the general rules for INAP provided in Recommendation Q.1208, consistent with the scope of IN CS-2 defined in Recommendation Q.1221.Recommendation Q.1228 provides:
• general extensions to the CS-1R INAP in support of IN CS-2 target services including: SCF initiated trigger management, GVNS service support, explicit ISDN supplementary service feature interaction support, service compatibility checks, general User to Service Interaction (UTSI), Specialized Resource Function (SRF) script processing, enhanced security, extended BCSM support, message store and forward, SCF/SDF extensions in support of distributed data management;
• protocol support for Call Party Handling capabilities based, in part, on future study items identified in CS-1R;
• protocol support for the Service Control Function (SCF) to SCF and Service Data Function (SDF) to SDF functional relationships to support distributed service logic execution and distributed data functions;
• protocol support for the Call Unrelated Service Function (CUSF) to Service Control Function (SCF) to support non-call related interactions between users and the SCF;
• additional details on services assumed from lower layers and generic interface security;
• validated SDLs for SSF-related procedure handling based upon Z.100 object-oriented Specification and Description language.Within the Q.122x Recommendation series, Recommendation Q.1228 describes the protocol realizing the Q.1224 distribution of Q.1223 Global Functional Plane functionality in a service and vendor/implementation independent manner, as constrained by the capabilities of the embedded base of evolvable network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations, as described in Recommendation Q.1225, and to evolve IN from IN CS-2 to some future CS-N.
