SCCP (Signalling Connection Control Part) is an SS7 user part protocol based on ITU-T Q.711-Q.719 specification set and ANSI T1.112 specification set. SCCP provides connection-less and connection-oriented services to its users (like TCAP, BSSMAP, RANAP etc.). Connection-less services of SCCP is widely used within telecommunications networks for implementing services like SMS, USSD, GSM services and IN services.

Sure Speed SCCP is Connection-less SCCP and it is based on our high performance Sure Speed architecture. Sure Speed SCCP may be used for implementing services within GSM and UMTS networks, connecting to various telecom nodes like HLR, MSC, SMS Center, USSD Center etc. Sure Speed SCCP integrates well with Sure Speed M3UA for an overall high performance and user-friendly experience. (Sure Speed SCCP may also be easily integrated with any MTP-3 or M3UA implementation.)
