SCCP

The Signaling Connection Control Part (SCCP) enabler provides the connectionless transport of TCAP messages. Both Class 0 (Basic) and Class 1 (Sequenced) connectionless services are provided. SCCP also provides Class 2 (connection oriented) services, which are typically used by Base Station System Application Part, Location Services Extension (BSSAP-LE). In addition, SCCP provides Global Title Translation (GTT) functionality. The SCCP software supports ITU-T, ETSI, ANSI, TTC, and Chinese variants of the protocol, enabling Signalware-based applications to be widely deployed.

Functions:

The SCCP software provides the means to:

• Route TCAP messages from end-to-end
• Translate from Global Title numbers to point code and subsystem numbers
• Establish and release connections

SCCP provides routing services for TCAP on an end-to-end basis, which supplements the point-to-point routing of MTP. In addition, SCCP translates Global Titles to point codes and subsystem numbers, simplifying routing table maintenance within a network. Further, SCCP provides connection-oriented services.

Services:

Services that can be defined using SCCP include:

• 800 Number
• Location

SCCP is ideal for applications such as 800 number services in which an 800 number needs to be translated into a specific point code and subsystem number.

When used in conjunction with BSSAP-LE, SCCP becomes an enabler for location-based services.

When used in conjunction with TCAP, SCCP becomes an enabler for all TCAP enabled services including those provided by CAP, GSM, TIA/EIA-41, and INAP.

Features:

The SCCP software is supported both on Signalware SS7 and Signalware SIGTRAN.

The SCCP software supports the development of distributed applications in a primary/standby mode of operation. The Signalware library supports application registration and restart as well as failover of an application to a standby process on a second computing element within the Signalware cluster.

Signalware supports the following standards:

• ITU-T Q.711-Q.714
• ANSI T1.112.1-112.4
• TTC JT-Q.711-714
• National NO.7 Signaling System Specification - Signaling System Control Part (SCCP) (China) GF010-95
• National NO.7 Signaling System Specification - Transaction Capability (TC) Part (CHINA) GF011-95
• GSM 08.06 for A-Interface support
