5G Signaling

5G signaling represents a significant evolution in mobile network architecture, introducing new concepts and security measures to address the challenges of next-generation communications.

5G Signaling Overview
Key characteristics of 5G signaling protocols
  • Service-Based Architecture (SBA) with HTTP/2 and JSON
  • Improved key management and hierarchy
  • Enhanced subscriber privacy (SUPI concealment)
  • Network slicing for isolated security domains
  • Unified authentication framework
  • Security Edge Protection Proxy (SEPP) for interconnect security
  • Support for massive IoT and ultra-reliable low latency communications (URLLC)
  • Integration of virtualization and cloud-native technologies
