Swisscom, Ericsson and AWS collaborate on 5G SA Core for hybrid clouds
Swiss network operator Swisscom have announced a proof-of-concept (PoC) collaboration with Ericsson 5G SA Core running on AWS. The objective is to explore hybrid cloud use cases with AWS, beginning with 5G core applications. The plan is for more applications to then gradually be added as the trial continues. With each cloud strategy (private, public, hybrid, multi) bringing its own drivers and challenges the idea here seems to be enabling the operator to take advantage of the specific characteristics of both hybrid and public cloud.
The PoC reconfirms Swisscom and Ericsson’s view of the potential hybrid cloud has as a complement to existing private cloud infrastructure. Both Swisscom and Ericsson are on a common journey with AWS to explore how use cases can benefit telecom operators.
The PoC will examine use cases that take advantage of the particular characteristics of hybrid and public cloud. In particular, the flexibility and elasticity it can offer to customers which can mean deployment efficiencies for use cases where capacity is not constantly needed. An example of this could be when maintenance activities are undertaken in Swisscom’s private cloud, or when there are traffic peaks, AWS can be used to offload and complement the private cloud.
Swisscom had already been collaborating with AWS on migrating its 5G infrastructure towards standalone 5G. In addition, it has also used the hyperscaler’s public cloud platform for its IT environments. Telco concerns linger [1.] around the use of public cloud in telecoms infrastructure (especially the core networks) for some operators, hybrid cloud is seemingly gaining momentum as a transitional approach.
Note 1. Telco concerns over public cloud:
- In a recent survey by Telecoms.com more than four in five industry respondents feared security concerns over running telco applications in the public cloud, including 37% who find it hard to make the business case for public cloud as private cloud remains vital in addressing security issues. This also means that any efficiency gains are offset by the IT environment and the network running over two cloud types.
- Many in the industry also fear vendor lock-in and lack of orchestration from public cloud providers. Around a third of industry experts from the same survey find it a compelling reason not to embrace and move workloads to the public cloud unless applications can run on all versions of public cloud and are portable among cloud vendors.
- There’s also a lack of interoperability and interconnectedness with public clouds. The services of different public cloud vendors are indeed not interconnected nor interoperable for the same types of workloads. This concern is one of the drivers to avoid public cloud, according to some network operators.

Mark Düsener, Executive Vice President Mobile Network & Services at Swisscom, says: “By bringing the Ericsson 5G Core onto AWS we will substantially change the way our networks will be built and operated. The elasticity of the cloud in combination with a new magnitude in automatization will support us in delivering even better quality more efficiently over time. In order to shape this new concept, we as Swisscom believe strategic and deep partnerships like the ones we have with Ericsson and AWS are the key for success.”
Monica Zethzon, Head of Solution Area Core Networks, Ericsson says: “5G innovation requires deep collaboration to create the foundations necessary for new and evolving use cases. This Proof-of-Concept project with Swisscom and AWS is about opening up the routes to innovation by using hybrid cloud’s flexible combination of private and public cloud resources. It demonstrates that through partnership, we can deliver a hybrid cloud solution which meets strict telecoms industry requirements and security while making best use of HCP agility and cloud economy of scale.”
Fabio Cerone, General Manager AWS Telco EMEA at AWS, says: “With this move, Swisscom is opening the door to cloud native networks, delivering full automation and elasticity at scale, with the ability to innovate faster and make 5G impactful to their customers. We are committed to working closely with partners, such as Ericsson, to explore new use cases and strategies that best support the needs of customers like Swisscom.”
“How to deploy software in different cloud environments – at a high level, it is hard making that work in practice,” said Per Narvinger, the head of Ericsson’s cloud software and services unit. “You have hyperscalers with their offering and groups trying to standardize and people trying to do it their own way. There needs to be harmonization of what is wanted.”

SKT with Global Telcos to Expand Metaverse Platform in US, Europe and Southeast Asia
On February 27 at MWC Barcelona 2023, South Korean network operator SK Telecom (SKT) signed a memorandum of understanding (MOU) with Deutsche Telekom and T-Mobile US to jointly explore opportunities for expanding its metaverse platform ifland into Germany and the U.S.

The three companies will begin to conduct market tests in the U.S. and Germany in the second quarter of this year, with the main goal of the trials being to try “more diverse metaverse services in Europe and the U.S.”
SKT, Deutsche Telekom and T-Mobile US will also produce content tailored to local preferences, and will jointly promote the metaverse offering.
The ifland platform is also set to be made available to more countries in South East Asia, and the telco has agreed a partnership with its Malaysian partner CelcomDigi to boost its ifland user numbers in the country and develop new business models. It will also be made available to all 11 subsidiaries of Axiata operating in the ASEAN (Association of South-east Asian Nations) and South Asian regions, including Malaysia, Indonesia, Sri Lanka, Cambodia, Bangladesh and Nepal.
SKT and Axiata also plan to develop “metaverse platform-related business models” and create business opportunities based on artificial intelligence (AI) to enhance the competitiveness of these models.
By expanding its metaverse service into the Southeast Asian market, where Korean culture such as K-content is gaining popularity, SKT expects to expand ifland’s services and develop new business opportunities.
“As we advance into the global market with our metaverse platform ifland, major telecommunications companies in each country and region play an important role as our partners,” said Ryu Young-sang, CEO of SKT. “Going forward, we will continue to work closely with diverse global companies to expand the scope of our metaverse service.”
“The collaboration between the leading Malaysian telecoms operator serving more than 20 million customers and global ICT leader SKT will set the stage for the nation’s metaverse development, and drive growth and digitalisation within the digital economy,” said Datuk Idham Nawawi, CEO of CelcomDigi. “We look forward to working together on leveraging innovative technologies and practices particularly in virtual spaces to develop and deliver a wider range of innovative solutions for our customers and Malaysian businesses.”
“Axiata is deeply committed to leveraging emerging technologies towards the inclusive advancement of Societies and Economies across Asia,” said Dr Hans Wijayasuriya, CEO of Axiata. “We are proud to partner with SKT and the ifland platform and consider the partnership a significant component of our participation in the metaverse going forward.”
SKT pointed out that each of the three operator partners has more than 100 million customers, giving it a solid foundation on which to expand the international impact of ifland. The company’s CEO, Ryu Young-sang, pointed out that partnering with major telcos “in each country and region” plays a key role in advancing ifland’s influence, so it plans to continue working closely with global companies to broaden the scope of the service.
SKT’s metaverse platform launched in June 2021 and after an initial collaboration with Deutsche Telekom, it aggressively moved to global expansion across North America, Europe, the Middle East and Asia in November 2022.

Cloud RAN with Google Distributed Cloud Edge; Strategy: host network functions of other vendors on Google Cloud
At MWC 2023 Barcelona, Google Cloud announced that they can now run the radio access network (RAN) functions as software on Google Distributed Cloud Edge, providing communications service providers (CSPs- AKA telcos) with a common and agile operating model that extends from the core of the network to the edge, for a high degree of programmability, flexibility, and low operating expenses. CSPs have already embraced open architecture, open-source software, disaggregation, automation, cloud, AI and machine learning, and new operational models, to name a few. The journey started in the last decade with Network Functions Virtualization, primarily with value added services and then deeper with core network applications, and in the past few years, that evolved into a push towards cloud-native. With significant progress in the core, the time for Cloud RAN is now, according to Google. However, whether for industry or region-specific compliance reasons, data sovereignty needs, or latency or local data-processing requirements, most of the network functions deployed in a mobile or wireline network may have to follow a hybrid deployment model where network functions are placed flexibly in a combination of both on-premises and cloud regions. RAN, which is traditionally implemented with proprietary hardware, falls into that camp as well.
In 2021,the company launched Google Distributed Cloud Edge (GDC Edge), an on-premises offering that extends a consistent operating model from our public Google Cloud regions to the customer’s premises. For CSPs, this hybrid approach makes it possible to modernize the network, while enabling easy development, fast innovation, efficient scale and operational efficiency; all while simultaneously helping to reduce technology risk and operational costs. GDC Edge became generally available in 2022.
Google Cloud does not plan to develop its own private wireless networking services to sell to enterprise customers, nor does the company plan to develop its own networking software functions, according to Gabriele Di Piazza, an executive with Google Cloud who spoke at MWC 2023 in Barcelona. Instead, Google Cloud would like to host the networking software functions of other vendors like Ericsson and Mavenir in its cloud. It would also like to resell private networking services from operators and others.
Rather than develop its own cloud native 5G SA core network or other cloud networking software (like Microsoft and AWS are doing), Google Cloud wants to “avoid partner conflict,” Di Piazza said. Google has been building its telecom cloud story around its Anthos platform. That platform is directly competing against the likes of AWS and Microsoft for telecom customers. According to a number of analysts, AWS appears to enjoy an early lead in the telecom industry – but its rivals, like Google, are looking for ways to gain a competitive advantage. One of Google’s competitive arguments is that it doesn’t have aspirations to sell network functions. Therefore, according to Di Piazza, the company can remain a trusted, unbiased partner.

Last year, the executive said that moving to a cloud-native architecture is mandatory, not optional for telcos, adding that telecom operators are facing lots of challenges right now due to declining revenue growth, exploding data consumption and increasing capital requirements for 5G. Cloud-native networks have significant challenges. For example, there is a lack of standardization among the various open-source groups and there’s fragmentation among parts of the cloud-native ecosystem, particularly among OSS vendors, cloud providers and startups.
In recent years, Google, Microsoft, Amazon, Oracle and other cloud computing service providers have been working to develop products and services that are specifically designed to allow telecom network operator’s to run their network functions inside a third-party cloud environment. For example, AT&T and Dish Network are running their 5G SA core networks on Microsoft Azure and AWS, respectively.
Matt Beal, a senior VP of software development for Oracle Communications, said his company offers both a substantial cloud computing service as well as a lengthy list of network functions. He maintains that Oracle is a better partner for telecom network operators because of it. Beal said Oracle has long offered a wide range of networking functions, from policy control to network slice management, that can be run inside its cloud or inside the cloud of other companies. He said that, because Oracle developed those functions itself, the company has more experience in running them in a cloud environment compared with a company that hasn’t done that kind of work. Beal’s inference is that network operators ought to partner with the best and most experienced companies in the market. That position runs directly counter to Google’s competitive stance on the topic. “When you know how these things work in real life … you can optimize your cloud to run these workloads,” he said.
While a number of other telecom network operators have put things like customer support or IT into the cloud, they have been reluctant to release critical network functions like policy control to a cloud service provider.
