Telecom networks are evolving rapidly. With the rise of 5G, IoT, and cloud-native architectures, operators face increasing pressure to maintain high availability, seamless connectivity, and scalable network infrastructures. However, legacy SS7-based systems still play a crucial role in global telecom operations.
That’s where SIGTRAN providers come in. They bridge the gap between legacy and IP-based telecom networks, ensuring that telcos can deliver reliable and scalable services without costly infrastructure overhauls. If you’re new to SIGTRAN and its role in modern telecom, check out this beginner’s guide to SIGTRAN for a detailed overview.
So, how exactly do these solution providers help telcos scale their networks and maintain reliability? Let’s break it down.

Why SIGTRAN Matters for Modern Telcos

Even as telecom networks transition to fully IP-based systems, SS7 signaling is still widely used for critical services such as:
  • Call setup and routing
  • SMS messaging (A2P and P2P)
  • Subscriber authentication and roaming
  • Fraud detection and security monitoring
Traditional SS7 networks rely on TDM (Time-Division Multiplexing) links, which are costly and do not scale efficiently. SIGTRAN (Signaling Transport) enables SS7 messages to be carried over IP networks, providing telcos with a cost-effective, flexible, and scalable signaling solution.

How SIGTRAN Providers Boost Network Reliability and Scalability

  1. Ensuring Seamless Interoperability Across Networks
    2. Modern telecom environments are complex, with operators running a mix of 2G, 3G, 4G, and 5G networks. Ensuring smooth communication across these technologies is critical. SIGTRAN Gateway providers enable interoperability between legacy SS7 systems and next-gen IP networks, ensuring that calls, SMS, and roaming services function seamlessly across different network infrastructures.

  2. Enhancing Global Roaming and Cross-Network Connectivity
    3. International roaming still relies heavily on SS7 signaling for subscriber authentication. Many telcos use SIGTRAN to route signaling messages over IP networks, ensuring:
    • Lower latency for roaming services
    • Improved handling of international voice and SMS traffic
    • Cost-efficient global connectivity
    According to GSMA, more than 50% of international voice roaming traffic still runs on SS7. SIGTRAN enables telcos to modernize their roaming infrastructure while maintaining compatibility with existing networks.

  3. Handling Network Growth and Demand Spikes
    4. With the increasing adoption of 5G and IoT, telecom networks must handle higher volumes of data and signaling traffic. This requires a scalable signaling infrastructure, and SIGTRAN delivers just that.
    SIGTRAN solution providers offer cloud-based solutions that allow telcos to scale their signaling capacity dynamically, ensuring optimal network performance without costly hardware upgrades.
    During peak traffic events such as Black Friday or major sports tournaments, telecom networks experience a surge in call and SMS traffic. SIGTRAN enables telcos to scale up capacity as needed, preventing congestion and service disruptions.

  4. Improving Network Reliability and Redundancy
    5. Network downtime can lead to significant revenue losses and customer dissatisfaction. Reliable telecom services require robust redundancy mechanisms to prevent outages.
    SIGTRAN solution providers enhance reliability through:
    • Load balancing: Distributes signaling traffic efficiently across multiple servers.
    • Failover mechanisms:Automatically reroutes traffic in case of server failures.
    • Geo-redundancy:Ensures backup signaling nodes in different locations, minimizing downtime risks.
    A leading telecom operator in Asia reduced its annual network downtime from six hours to less than ten minutes by implementing SIGTRAN-based redundancy systems.

  5. Enhancing Security Against SS7 Fraud
    6. SS7 networks are vulnerable to attacks such as SMS interception, call spoofing, and location tracking. With SIGTRAN, telcos can implement advanced security measures, including:
    • Encryption and authentication: Prevents unauthorized access to signaling data.
    • Fraud detection and firewalls: Identifies suspicious signaling patterns and blocks potential threats.
    • Geofencing: Protects against unauthorized location tracking.
    A report by Positive Technologies found that 78% of SS7 networks are vulnerable to location-tracking attacks. SIGTRAN firewalls provide an additional layer of security, reducing exposure to such risks.


Choosing the Right SIGTRAN Provider

Not all SIGTRAN providers offer the same level of service. When selecting a SIGTRAN solution for your telecom network, key factors to consider include:
  • Scalability: The ability to handle increasing signaling traffic.
  • Reliability: Availability of geo-redundant architectures and failover mechanisms.
  • Security: Inclusion of firewalls, encryption, and fraud detection tools.
  • Interoperability: Compatibility with legacy SS7 and modern IP-based networks.
