The SS7 Protocol and SIG Transport: A Backbone for The 4G/LTE
While contemporary 4G/LTE networks offer substantial data rates, their underlying infrastructure often relies on established protocols: SS7 and SIGTRAN. Initially designed for the PSTN , SS7 provides the essential signaling functionality for verification , network mobility , and location information, all of which are leveraged within the 4G/LTE ecosystem. SIGTRAN, in effect , transports SS7 signaling messages over packet-switched networks, bridging the conventional SS7 world with the new 4G/LTE architecture . Consequently, these apparently outdated technologies remain integral components, enabling the advanced operations of contemporary mobile networks.
Mobile Signaling: The Role of Signaling System No. 7 and SIG
LTE signaling relies heavily on legacy signaling protocols, mainly Signaling System No. 7 and SIGTRAN . Originally developed for public telephone networks, offers critical functions like call establishment, management, and roaming information exchange . A protocol links this legacy SS7 infrastructure to the packet-switched world of LTE, allowing the movement of signaling messages between LTE network elements and public telecommunications . Essentially , the Signaling System constitutes the basis for many LTE signaling procedures, while Signaling Transport acts as the interpreter , adapting Signaling System No. 7 messages for mobile’s packet-based architecture .
