Next-Gen Signaling Starts with SS7/Sigtran

Experience zero signaling problems in your network with ComCode’s high-performance and tested SS7/Sigtran Stack.

Behind every phone call you make or SMS you send, there’s a signal transmitting in the background, which is SS7/Sigtran. It is something that users may not be able to see, but it’s the element that runs the global telecom networks. SS7 was first standardized in 1980, but its development started way before to replace manual signaling. At ComCode, we combine the strength of SS7 with the capacity of Sigtran to help operators build modern signaling systems. If you’re an MNO, MVNO, or enterprise carrier, our stack can keep your network fast.

What is the SS7/Sigtran Stack?

The SS7 (Signaling System No. 7) stack is a set of protocols employed to establish and tear down telephone calls, manage mobile roaming, send SMS messages, and perform number translation and billing. It was originally designed for circuit-switched networks. Over time, the demand to abandon expensive, hardware-based signaling gave rise to Sigtran—a modern extension that allows SS7 messages to travel over IP networks.

This progress means telecom operators can now carry legacy signaling protocols using internet-based systems without losing speed, quality, or security. When combined, the SS7 and Sigtran protocols form a stack that enables high-volume, real-time communication across global networks for both legacy systems and futuristic telecom services.

The Pillars of SS7/SIGTRAN Performance

The SS7/SIGTRAN stack is made of several components, and without them, it is impossible to transmit a signal on a network.
  • MTP (Message Transfer Part): This component is responsible for the transfer of signaling messages. It does error checking, message routing, and delivery confirmation. 
  • SCCP (Signaling Connection Control Part): SCCP adds advanced routing functions to SS7 to support more complicated services, such as mobile user location updates and toll-free number services. 
  • TCAP (Transaction Capabilities Application Part): TCAP is designated for managing the exchange of transaction-related messages, such as prepaid balance checks, mobile authentication, and mobile number portability. 
  • MAP (Mobile Application Part): MAP is used in mobile networks to provide services like SMS delivery and roaming. It manages communication between mobile devices and network elements.
  • ISUP (ISDN User Part): ISUP is used for call setup, tear-down, and management in telecommunication systems. It helps establish and manage voice calls between different telecom providers.

Breaking Down the Process of SS7/SIGTRAN Stack

To fully understand the SS7/SIGTRAN stack, it’s important to know how it works. The SS7/SIGTRAN stack combines multiple layers of communication protocols, each with a distinct role.
  • SS7 Layer: In the older SS7 architecture, this layer is in charge of call setup, SMS routing, billing, and other main telecom services. It ensures that messages are routed through the network.
  • SIGTRAN Layer: SIGTRAN encapsulates SS7 messages and transmits them over modern IP networks using protocols like SCTP and M3UA. This layer checks whether SS7 signaling is compatible with the IP systems or not.
  • SCTP (Stream Control Transmission Protocol): This protocol facilitates message transfer. It also has error-handling features for telecom networks.
  • MTP3: The Message Transfer Part 3 (MTP3) layer is credited for routing signaling messages across the network to the right destination.
Together, these layers handle the routing, error detection, and communication between different telecom entities like switches, gateways, and user devices.
