While modern 4G/LTE networks offer remarkable data rates, their core infrastructure often relies on established protocols: SS7 and SIGTRAN. Initially designed for the PSTN , SS7 provides the vital signaling capability for authorization, subscriber services, and location information, all of which are employed within the 4G/LTE ecosystem. SIGTRAN, in effect , carries SS7 signaling messages over data networks, connecting the traditional SS7 world with the new 4G/LTE framework. Consequently, these seemingly outdated technologies remain integral components, powering the complex operations of modern mobile networks.
LTE Signaling: A Role of Signaling System No. 7 and SIGTRAN
LTE communication depends heavily on established signaling protocols, primarily the Signaling System and SIG . Originally designed for older telephone networks, provides essential functions like session establishment, management, and mobility information transfer . SIGTRAN, bridges this older SS7 infrastructure to the IP world of LTE, allowing the conveyance of control messages via LTE network nodes and public networks. In short , Signaling System No. 7 forms the foundation for many LTE signaling procedures, while Signaling Transport functions as the translator , adapting Signaling System No. 7 messages for LTE’s IP-based architecture .
