CASE STUDY
Epsilon Supports BT SigTran Signalling
BACKGROUND
BT, a leading global telecommunications provider, sought to enhance its wholesale mobile roaming service by transitioning from TDM to IP-based signalling. As mobile network operators increasingly adopted IP technology, BT needed a scalable, cost-effective solution to extend its IP signalling infrastructure and support the growing demand for IP-based roaming services. The goal was to offer mobile operators improved global reach, resiliency, and cost-efficiency, ensuring seamless connectivity for roaming services across different regions, including Africa and the Middle East.
EPSILON’S SOLUTION
Epsilon provided BT with a flexible and efficient solution that facilitated the migration from TDM to IP for its Mobile Roam service. Epsilon’s SigTran solution enabled BT to quickly deploy and scale its IP signalling infrastructure, offering mobile operators a reliable, cost-effective way to interconnect and support roaming services globally. With Epsilon’s support, BT could extend its reach and enhance the quality and security of its wholesale roaming services, serving over 900 MNOs in 199 countries and offering seamless roaming capabilities on both inbound and outbound networks.
Frequently Asked Questions
1. How do Signalling Gateways and Media Gateways work together?
The Signalling Gateway (SG) handles SS7–to–IP call signalling, while the Media Gateway (MG) manages the actual voice/media conversion (TDM–to–RTP). They work together to complete a call.
2. What is SigTran, and why is it needed?
SigTran is a set of protocols that transport SS7 signalling over IP. It is needed to transition from TDM networks to IP-based signalling, reducing costs and improving scalability.
3. How does SigTran differ from traditional SS7 over TDM?
Traditional SS7 uses E1/T1 (TDM), while SigTran transports SS7 over IP using SCTP. SigTran offers cost savings, flexibility, and redundancy.
4. Can SigTran work with other signalling protocols like SIP?
Yes, SigTran can work alongside SIP by enabling interoperability between legacy SS7 networks and modern IP-based VoIP solutions like SIP. This allows seamless communication across different network infrastructures, making it easier to integrate traditional telephony systems with next-gen IP networks.
5. What are the redundancy and failover mechanisms in SigTran?
SCTP provides multi-homing (multiple IP paths), and load sharing or failover can be configured across multiple SGs and ASPs.
