SS7 & Intelligent Network Fundamentals

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 technologies have captured the attention of millions, many forget or do not realize the importance of SS7.Every call in every Public Switched Telecommunications Network (PSTN) system 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.

The term “Intelligent Network” (IN) pertains to a framework for intelligence in support of Time Division Multiplex (TDM) circuit-switched networks. As opposed to IP-based networks, typified by intelligence at the edge and very flat, democratized communications, IN provides support for carrier-controlled networks with intelligence residing in centralized databases.
