BIG-IP Next Security Edge Protection Proxy

Secure 5G Roaming and Network Interconnection

Standards-based SEPP

To gain the full benefit of a 5G Standalone architecture that goes beyond the capabilities of a 4G network—such as improved 5G Security functionality, Network Slicing, or other IoT focused services—a 5G roaming architecture based on SEPP is needed.

3GPP defines the SEPP function to address 5G roaming signaling across the N32 interface between two different 5G networks that is used for internal roaming or interconnection between public mobile networks or private mobile networks.

N32 Interface Support Support for N32-c and N32-f with TLS encryption
TLS Broker Simplified integration between different TLS versions or clear text connections
Monitoring Feed Providing an unencrypted feed for the TLS secured signaling messages towards monitoring systems

SEPP for roaming

SEPP provides secure end-to-end signaling across the N32 using HTTP/2 for national and international roaming.

N32 Load Balancing Intelligent load balancing of messages across the N32 interface
Authentication and Encryption Authentication and encryption of all HTTP/2 roaming messages

SEPP for 5G network interconnection

SEPP plays a critical role for Private Mobile networks, providing a standards-based secure method for interconnecting a Private 5G network with the Public mobile network, as well as interconnecting Public mobile networks (like for SMS over SBI.)

Control Plane Security Secure signaling for standalone non-public networks
Cloud-Native Cloud-native architecture for dynamic scaling and Edge deployments
