Telefónica Facilitates the First Multi-Operator 4G Roaming Experience with Participating Partners from over 15 Countries

Telefónica (NYSE:TEF) (LSE:TDE) will, at this year’s Mobile World Congress, facilitate the first technological multi-operator 4G (LTE) Roaming experiment to offer roaming high-speed data services. Telefónica Spain will open up its 4G/LTE network to a large group of selected operators and technological partners from over 15 countries.

Delegates from those operators - that include the UAE, South Korea, Russia, the United States, Hong Kong, France, Portugal, Saudi Arabia and Italy, among others - as well as the Telefónica operations that already have a commercial LTE service (United Kingdom, Germany, Brazil, Mexico and Colombia) in place will, for the first time, enjoy the experience of roaming high-speed data services, simultaneously and without fissures. One of the most important characteristics of this new technology is that it replicates the same 4G service quality level usually enjoyed in respective countries of origin.

Telefónica´s technical and wholesale teams in Spain have accelerated the deployment of recommendations otherwise still in the final stages of planning by the GSMA/3GPP (in whose standardisation groups Telefónica actively participates) to enable this pilot.

Telefónica as such takes the lead in marking a new technology milestone to demonstrate it is ready to include roaming high-speed LTE services in its current extensive roaming coverage, which includes over 700 operators worldwide.

Telefonica will use the LTE Diameter Exchange service offered by Telefónica Global Solutions to provide this experience. It is a service model designed in partnership with Aicent and in line with an Over IPX Services policy. It represents the largest generation of LTE traffic routing (Diameter) signalling, enabling customers to outsource LTE Roaming interoperability function while at the same time extending LTE international coverage.

In addition, in order to verify availability and quality, several Telefónica units, both local and international, have worked with Keynote SIGOS, the world leader in fraud detection and automatic end-to-end tests to measure user experience in telecommunication networks and services. Throughout the pilot, Telefónica will use the largest existing infrastructure to trial these roaming services. This system provides access to multiple networks in countries around the world, to permanently monitor roaming services and increase customer satisfaction.

Finally, and coinciding with the Congress, additional test probes have been installed at key locations around Barcelona, including the Mobile World Congress venue itself. This enables Telefónica to simulate global traffic across all the locations, before and during the event, in order to guarantee quality of the service to its customers.

SYS-CON Events announced today that the "First Containers & Microservices Conference" will take place June 9-11, 2015, at the Javits Center in New York City. The “Second Containers & Microservices Conference” will take place November 3-5, 2015, at Santa Clara Convention Center, Santa Clara, CA. Containers and microservices have become topics of intense interest throughout the cloud developer and enterprise IT communities.
There is no question that the cloud is where businesses want to host data. Until recently hypervisor virtualization was the most widely used method in cloud computing. Recently virtual containers have been gaining in popularity, and for good reason. In the debate between virtual machines and containers, the latter have been seen as the new kid on the block – and like other emerging technology have had some initial shortcomings. However, the container space has evolved drastically since coming on...
With worldwide spending on cloud services and infrastructure growing by 23% in 2015 to $118B, it is clear that cloud services are here to stay.

In his session at 16th Cloud Expo, Michael Kane, Senior Manager at Dyn, will explore how Internet performance affects your end-user...

While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor.

Spatial teleconferencing introduces the concept of acoustic spatial separation between confe...

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...
The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. Acco...
Gartner predicts that the bulk of new IT spending by 2016 will be for cloud platforms and applications and that nearly half of large enterprises will have cloud deployments by the end of 2017. The benefits of the cloud may be clear for applications that can tolerate brief periods of downtime, but for critical applications like SQL Server, Oracle and SAP, companies need a strategy for HA and DR protection. While traditional SAN-based clusters are not possible in these environments, SANless cluste...
You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, will cover the union between the two topics and why this is important. He will cover an overview of Immutable Infrastructure then show how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He will end the session with some interesting case study examples.
