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.
Signaling Interworking in the Transition from 4G to 5G
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.

Diameter
Diameter signaling and traffic management is required to meet your growing customers’ demands
F5 offers security with a consolidated Diameter signaling platform that optimizes and protects the signaling network.
Secure
F5 Diameter firewall delivers a high-performance, stateful security solution to guard the diameter protocol against network threats.
Scalable
Enables comprehensive L4–L7 load balancing solutions including smart Diameter session stickiness.
Available
Advanced Diameter load balancing distributes signaling traffic across multiple servers.
GPRS Tunneling Protocol (GTP)
GTP traffic growth is higher than ever
Satisfy data-hungry consumers and maintain high performance by accelerating GTP tunnels and offloading GTP data traffic.
Secure
Protects against GTP security issues such as confidential data disclosures, network overloads, and fraud activities.
Scalable
As data over mobile networks grows, with more network nodes needed, GTP load balancing helps operators scale network traffic handling.
Traffic Optimization with Network Slicing
GTP allows providers to create different SGW-PGW network slices based on granular characteristics in 4G networks.
Improved Roaming with GTP Proxy and APN correction
Allows providers much better control over roaming services offered to mobile virtual network operators.
Session Initiated Protocol (SIP)
SIP solutions as part of a secure system for the IMS network infrastructure
Ensures interoperability of SIP requests and responses throughout the IP infrastructure.
Secure
Provide security for user traffic with a firewall solution with SIP ALG monitoring and SIP control channel validation.
Scalable
Scales to handle millions of subscribers calls simultaneously.
Reliable
Enhances reliability at carrier-grade levels, including session synchronization and full failover capabilities with no connection loss.
