Open source is well established in the IT world, and it's coming to telecom

Why it makes sense to open-source ECOMP

From its inception, AT&T’s ECOMP platform for NFV automation has attracted attention because the project has been led by a service provider rather than a vendor or a standardization body. The recent decision to convert ECOMP to an open source project and irrevocably hand the majority of its code to the Linux Foundation has put it back in the spotlight. Well-established in the IT world, the open source model remains something of an alien concept in telecoms. You could say that its ethos of free licensing, open collaboration and fast-paced development is diametrically opposed to our industry, which is built […]  More >>

Elementary, my dear Watson

Early VoLTE rollouts presented a number of challenges for service providers, including VoLTE call drops due to timeout. This particular issue appeared to be IMS related, but the Core/IMS team could not identify its root cause. IMS had just been deployed, so the inability to pinpoint exactly where the issue lay was attributed to lack of knowledge. The mystery was solved after considering data from the radio access network (RAN). It then became evident that the VoLTE call timeout was a RAN issue, caused by noncontiguous radio coverage when users moved between cells. To resolve the matter, the RAN and […]  More >>
End in mind

Start with the end in mind

The need to better manage how end users experience network performance It is rush hour on a rainy Wednesday morning. The metro station is heaving with commuters. The departure board shows the next train leaving at 08.09, but it is already 08.16. No, time travel has not been invented yet. The train is late, and the board has not been updated with the expected time of train departure. The reason for the delay is unknown. It could be a signaling failure, a train fault, leaves on the line, or even track congestion.Whichever the reason, the commuters’ experience of the metro […]  More >>

Confused by 5G news headlines? Why you are not alone

Do you like abstract paintings? Such paintings are inherently open to interpretation. Different people perceive different things, and most uninitiated observers may just see a ‘messy’ picture. But there is logic and design behind – at least some – abstract paintings. This is the case with 5G too. Following vague news and misleading announcements, 5G currently resembles an abstract painting. But the ambiguous or ‘messy’ 5G picture can become clearer if we look into 5 key areas of confusion. The trials blur The tsunami of news about 5G trials has mainly focused on the 5G new radio (NR). With standardization […]  More >>

What 5G is about: an alternative view

How much do you know about 5G? Have you been following the relentless flow of 5G news? If you were to choose 5 words to describe 5G, which ones would you pick? It would be interesting to see what you think 5G is about. But what if we were to ask those who have absolutely no knowledge of 5G and would play such a word game without any preconception, just for fun? As discussed with 2 friends who needed to entertain a group of primary school children at a party, the following game could potentially be exciting: Use a one-page […]  More >>

Network Testing Challenges: NFV and SDN

Compressing testing cycles and improving service quality – no longer mutually exclusive Network functions virtualization (NFV) and software-defined networking (SDN) are enabling technologies to increase the flexibility and speed to deploy new services at a fraction of the cost of physical networks. Looking ahead to 5G and the proliferation of Internet of Things (IoT) use cases, virtualization and dynamic service chaining will become essential for managing the scale and customization that will be required to connect 25B objects the industry is anticipating. In a recent report from Coleman-Parkes Research for Amdocs, about half of the 80 service providers surveyed view […]  More >>

VoLTE: No easy path – but worth it

It might not be as hard work as trekking across the Andes, but while there is no easy path to rolling out Voice over LTE (VoLTE), the rewards can be amazing. Careful preparation is essential and by planning well and optimizing the network for a VoLTE launch, service providers can provide the ultimate user experience in voice services. But failure to plan a VoLTE launch properly and prepare the network to be ‘VoLTE ready’, will result in poor service quality and a bad customer experience. Customers will have high expectations for the new digital voice service after many years of […]  More >>

Network Testing: Having the right tools at the right time

Regardless of the subject, change is good – but there’s a downside. Every change brings an equal and opposite toolset that is needed to manage that change. OK, Newton might be rolling in his grave, but the point is that new technologies usually bring added costs to testing-deploy cycles, in both engineering resources and new tools, whether it be in-house, commercial or open toolsets. Given the rapid pace of disruption, it’s not surprising that tools – or the lack thereof – are a hot topic for network testing teams. In a recent survey, conducted by Coleman-Parkes on behalf of Amdocs, […]  More >>

Overcoming the VoLTE challenges

Making the transition from circuit switched voice to Voice over LTE (VoLTE) for mobile voice services is yet another key step forward in the long evolution of the telephone. For well over 120 years, voice services have been the mainstay for service providers and the technology has evolved from analogue to digital, and from fixed line to mobile. For each step the advantages and rewards have been many. VoLTE presents the next step change in mobile voice services by offering customers HD voice and faster call setup times, with the additional benefit of bandwidth saving for the service provider. But […]  More >>

Network Testing: Busting the 9-week barrier

Network Functions Virtualization (NFV) and software-defined networking (SDN) promise to save service providers millions in hardware costs and shave weeks off the time to deliver and scale network services. Unfortunately those are forward-looking advantages that have little impact on today’s project schedules or the time and effort it takes new services to go from testing to production-ready. According to a recent survey conducted by Coleman-Parkes Research on behalf of Amdocs, getting the test-deploy cycle below nine weeks is the new benchmark! But it’s proving frustratingly elusive for engineering teams trying to balance intense market pressures to deliver broader coverage, faster […]  More >>
