SIGTRAN Stack | SS7 Stack | SIGTRAN Protocols

SIGTRAN & SS7 Protocol Suite

Through years of engineering & innovation, Shabd Communications have designed and developed very high performance & reliable SIGTRAN and SS7 protocol suite. We call this Sure Speed Architecture (SSA). We write protocols based on Sure Speed Architecture framework. This ensures that all our products meet high performance demand of the modern telecommunications networks. Some of the key advantages of Sure Speed Architecture are as following:

1) High Performance Design
2) Optimized Memory Utilization
3) Highly efficient Hash Tables enabling fast data access
4) Support for KPI Collection
5) Diagnostics Collection for faster real time troubleshooting
6) Logs for real time execution tracing
7) In built Timers that help in avoiding race conditions
8) Portable error capturing mechanism

We have over 250 customers across the world who are using our protocol stacks to implement their products. To know more about the Sure Speed SS7 & SIGTRAN protocol suite, please contact: This email address is being protected from spambots. You need JavaScript enabled to view it.

SCCP (Signalling Connection Control Part)

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 CL SCCP is Connection-less SCCP and it is based on our high performance Sure Speed architecture. Sure Speed CL 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 CL SCCP integrates well with Sure Speed M3UA for an overall high performance and user-friendly experience. (Sure Speed CL SCCP may also be easily integrated with any MTP-3 or M3UA implementation.)

SIGTRAN M3UA

M3UA (MTP-3 User Adaptation Layer) is a protocol for supporting the transport of SS7 MTP-3 User Signaling (e.g. ISUP or SCCP messages) over IP using the services of the Stream Control Transmission Protocol (SCTP). Also, provision is made for protocol elements that enable a seamless operation of the MTP-3 User peers in the SS7 and IP domains. This protocol would be used between Signaling Gateway (SG) and Media Gateway Controller (MGC) or IP-Resident Database, or between two IP-based applications. It is assumed that SG receives SS7 signaling over a standard SS7 interface using the SS7 message Transfer Part (MTP) to provide transport.

Sure Speed M3UA is a high performance implementation of M3UA protocol (RFC 4666, RFC 3332). It is based on our proprietary Sure Speed framework that ensures a high level of performance for all our protocol implementations.

TCAP (Transaction Capabilities Application Part)

TCAP (Transaction Control Application Part) is an SS7 user part protocol based on ITU-T Q.771-Q.779 specification set. Sure Speed TCAP is based on our proprietary Sure Speed Architecture that provides reliability and high performance design. TCAP layer is used for performing remote operations and to fetch data from remote databases. It takes services of Connection-less SCCP for implementing many value added services and core services like SMS, USSD, GSM services and IN services. TCAP is used by MAP, CAP, INAP and other applications for implementing the signalling logic of modern telecommunication networks. In other words, TCAP is an integral part of modern telecommunication networks.

Sure Speed TCAP supports distributed application development. This means that several instances of TCAP layer can be run on one or more than one systems and traffic can be distributed between them. This helps in building a high capacity system that can provide failsafe design.

GSM MAP (Mobile Application Part)

MAP (Mobile Application Part) is an SS7 user part protocol based on 3GPP TS 29.002 specification. Sure Speed MAP is based on our Sure Speed Architecture that provides reliability and high performance design. MAP layer is used for performing remote operations and to fetch data from remote databases. It takes services of Connection-less SCCP and TCAP for implementing many value added services and core services like SMS, USSD, Equipment Management services (EIR) etc. MAP is an integral part of the mobile networks and used for Value Added Services.

Sure Speed TCAP supports distributed application development. This means that several instances of TCAP layer can be run on one or more than one systems and traffic can be distributed between them. This helps in building a high capacity system that can provide fail safe design.
