Learn More about SS7
Signaling System number Seven (SS7) is a critical component of modern telecommunications systems. SS7 is a communications protocol that provides signaling and control for various network services and capabilities. Being a layered protocol, SS7 provides various protocol levels for connection oriented and connectionless (database) signaling in fixed and mobile networks.
While the Internet, wireless data, and related technology have captured the attention of millions, many forget or do not realize the importance of SS7. Every call in every network is dependent on SS7. Likewise, every mobile phone user is dependent on SS7 to allow inter-network roaming. SS7 is also the “glue” that sticks together circuit switched (traditional) networks with packet switched (IP based) networks.
