Signaling System 7 and SIG Transport: A Basis for 4G
While modern 4G/LTE networks offer substantial data rates, their underlying infrastructure often relies on older protocols: SS7 and SIGTRAN. First designed for the PSTN , SS7 provides the essential signaling capability for verification , roaming , and geographical information, all of which are utilized within the 4G/LTE ecosystem. SIGTRAN, in turn , transmits SS7 signaling messages over data networks, connecting the conventional SS7 world with the current 4G/LTE framework. Therefore , these apparently outdated technologies remain crucial components, enabling the sophisticated operations of current mobile networks.
Mobile Signaling: A Role of The Signaling System and Signaling Transport
LTE signaling utilizes heavily on legacy signaling protocols, notably Signaling System No. 7 and SIGTRAN . Originally developed for older telephone networks, furnishes important functions like call establishment, management, and roaming information transfer . SIGTRAN, links this older SS7 infrastructure to the IP world of LTE, facilitating the movement of information messages between LTE network elements and public communication . Briefly, Signaling System No. 7 constitutes the foundation for many LTE management procedures, while Signaling Transport functions as the interpreter , converting Signaling System No. 7 messages for mobile’s packet-based architecture .
