This tutorial provides an overview of Signaling System No. 7 (SS7) network architecture and protocols.
SS7 is a set of telephony signaling protocols that are used to set up most of the world’s public switched telephone network (PSTN) telephone calls.
SS7 primarily sets up and tears down telephone calls, but other functions include number translation, prepaid billing mechanisms, local number portability, short message service (SMS), and a variety of mass-market services.
