Technology, operations and management kept under one umbrella so customers don’t need to worry about platforms, operations, analytics, and reporting
Deutsche Telekom Global Carrier has introduced Magenta Security Roaming which it said offers an ecosystem of secure connectivity for all protocols currently used by its customers: 2G, 3G, 4G, 5G non-standalone (NSA) and 5G standalone (SA). For each protocol, corresponding protection layers are in place which work in unison: SS7 Firewall, Diameter Edge Agent (DEA) Firewall, Diameter End-to-End Signalling Security (DESS), phase 1, as well as Security Edge Protection Proxy (SEPP) in several configurations.
The service is available to all the wholesaler’s customers, both its own group national operator companies (NatCos), as well as operators across the globe. The new concept comprehensively addresses operators’ increasing need for low-latency, reliability and security when roaming in today’s interconnected world.
Deutsche Telekom Global Carrier provides all Magenta Security Roaming services with dedicated support and SLAs. The service is designed to help maintain business by increasing the quality of operators’ cyber-defence systems, while reducing cost and complexity, according to the operator. As roaming security will become increasingly heterogenous throughout the world, Magenta Security Roaming offers a way to connect each destination with the top security as required by both operators.
5G SA roaming
For those operators which have already enabled 5G SA roaming, Magenta Security Roaming guarantees that they have options when interconnecting with each other by choosing the security measures they need. Telcos can outsource investment and operation of 5G SA roaming with Magenta Security Roaming’s outsourced SEPP solutions.
They can also opt for hosted SEPP maintenance services, as well as “composite scenarios” that connect individual roaming partners most efficiently. These include Deutsche Telekom Global Carrier’s new Group hosted SEPP for Family & Friends services specifically dedicated to its internal (NatCos) and external operator customers.
Deutsche Telekom Global Carrier claims it is the only carrier to offer DESS, phase 1 for 4G and 5G NSA services, which guarantees end-to-end authentication of signalling messages. “The combination of Diameter Firewall and DESS, phase 1 enables the world’s most secure LTE and 5G NSA exchange between mobile operators,” stated the telco.
“Security in roaming is a major issue in our industry. For the first time, we work with 5G SA as a technology where security is built in, while we still have to protect all the other protocols effectively to ensure roaming security across the board,” said Deutsche Telekom Global Carrier VP voice and mobile solutions Nicholas Nikrouyan.
“Magenta Security Roaming is our answer to this all-or-nothing scenario with highly innovative roaming security services, as well as our world-exclusive offer of DESS, phase 1,” he said. “Our innovative roaming concept allows us to avoid 5G hubbing and move to a world where security is there by design.”
First hosted SEPP 5G SA roaming
Last October, T-Mobile US and Deutsche Telekom Global Carrier completed successful testing of 5G Standalone (5G SA) roaming, utilising the wholesaler’s Security Edge Protection Proxy (SEPP) to complete the world’s first hosted SEPP 5G SA roaming T-Mobile US and Sunrise and a direct SEPP to SEPP interconnect with AIS Thailand.
The program used Deutsche Telekom Global Carrier’s Internet Protocol Exchange (IPX) and Hosted Security Edge Protection Proxy (SEPP) solutions with Sunrise and AIS, successfully completing 5G SA roaming between the US and Switzerland and the US and Thailand.
The telco said 5G SA roaming networks will offer faster speeds, lower latency, and higher capacity compared to non-standalone (NSA) networks. SA roaming is also crucial for supporting massive IoT deployments and critical IoT applications.
