3G and 4G Mobile Network Signaling and Roaming Security

F5 is a leader in signaling security, congestion management, and overload control with a wide range of Diameter, GTP, and SIP signaling solutions.

Signaling and Roaming Security. Diameter, GTP, and SIP Solutions

Service providers need to resolve the challenges that come with massively increased signaling traffic volume for 4G traffic. F5 is a leader in signaling security, congestion management, load balancing, and overload control with a range of Diameter (the 4G successor of SS7), GTP, SIP, and HTTP signaling solutions.

Secure

Ensure signaling security above and beyond GSMA Fraud and Security Group recommendations for Diameter and GTP Security.  

Scalable

A comprehensive range of congestion management and load balancing solutions and other capabilities which maximize signaling scalability.

Available

Increased network availability across the network – for example, by distributing traffic across multiple servers and GTP- based Access Point Name (APN) -based DNS resolutions for traffic management.

The path from 4G to 5G

Service providers need to plan out their signaling migration path from 4G to 5G. Unlimited scalability is critical in a mobile network. They need to manage their 4G control plane traffic and signaling with Diameter session-oriented load balancing technology along with interworking with 5G HTTP/2 signaling.
