The SS7 Protocol and SIG Transmit : A Foundation for 4G
While today's 4G/LTE networks offer impressive data rates, their underlying infrastructure often relies on older protocols: SS7 and SIGTRAN. Originally designed for the PSTN , SS7 provides the vital signaling support for read more verification , network mobility , and positional information, all of which are leveraged within the 4G/LTE ecosystem. SIGTRAN, in effect , transports SS7 signaling messages over data networks, linking the conventional SS7 world with the current 4G/LTE framework. Consequently, these seemingly outdated technologies remain crucial components, powering the sophisticated operations of modern mobile networks.
4G Signaling: The Role of The Signaling System and SIGTRAN
LTE transmission relies heavily on established signaling protocols, notably the Signaling System and SIGTRAN . Originally designed for older telephone networks, offers important functions like call establishment, management, and roaming information transfer . Signaling Transport, bridges this existing SS7 infrastructure to the data world of LTE, facilitating the conveyance of information messages between LTE network components and external telecommunications . In short , the Signaling System forms the core for many LTE management procedures, while Signaling Transport functions as the intermediary, converting the Signaling System messages for LTE’s packet-based structure .
