For years, SS7 served as the foundation for mobile network signaling, managing call setup and details. However, the migration to Advanced LTE introduced a challenge: how to incorporate this established protocol with the contemporary packet-switched architecture. SIGTRAN emerged as the solution, enabling the transfer of SS7 signaling across 4G/LTE networks, effectively converging these apparently distinct systems to ensure continued service reliability and connectivity.
The Foundation: Grasping The SS7 Protocol and SIGTRAN
To fully grasp this intricate architecture, it’s crucial to delve into its underlying building blocks. Signaling System No. 7 (SS7), originally designed for traditional circuit-switched networks, provides the framework for managing network messages. SIGTRAN, short for Signaling Transport, then connects this signaling system world with the data networks, enabling critical configuration information to be shared between network nodes. Absent this technologies, LTE’s performance would be unworkable or considerably impaired.
