A service may not be confined to an operator's network, and may originate from outside the network domain. One key component of 5G radio access is an innovative air interface called New Radio (NR), which is designed primarily for new spectrum bands. Per the recent collaboration, the 5G data and voice calls were made on Ericsson’s 5G infrastructure and harnessed the next-gen technology of Oppo … Such a system can sense data, analyze it, make decisions, and control actuation – providing surveillance, for example, or implementing distributed feedback control and monitoring critical components, and so on. New business models are being created with a focus on distributed cloud services and programmability of networks toward the edge. A generic use case, the massive number of geographically dispersed devices falls under the mMTC service. Most of these devices are characterized by low cost/ complexity (half duplex, low power, single antenna), long battery life (more than 10 years) and have significantly improved coverage (a 15-20dB better link margin than LTE). We also cover the Ericsson framework for cloud-native design and operations. Ericsson and O2 are also upgrading the existing 2G/3G/4G sites, and developing an innovation cluster as part of a trial platform to evaluate future mobile architecture, technology and systems. The great majority indicated they intend to make significant changes to their businesses in order to take maximum advantage of 5G when it arrives. 5G at the "G" - Ericsson and Telstra trial 5G at Melbourne Cricket Ground. Rogers today announced that it has begun deploying its 5G core network, powered by Ericsson, in Toronto, Ottawa, Montreal and Vancouver to support future 5G … Network management of entities in 5G systems will be able to automate and orchestrate a range of lifecycle management processes, and will be capable of coordinating complex dynamic systems of applications, cloud, transport and access resources. Please see below for more information on 3GPP 5GC which is part of Release 16 and as yet has not been submitted to … The Swiss operator recently carried out live 5G SA voice and data calls using Voice over New Radio (VoNR) and carrier aggregation along with Ericsson Spectrum Sharing. Since this is a multi-year journey that will require several changes to the network architecture as well as tools for automation and management processes, it’s important to get started sooner than later. It is an incremental process, enhancing the current network in a step-by-step fashion. Option 2: An alternative deployment option is to deploy CNFs over a bare metal infrastructure to leverage the full benefits of cloud native transformation. Network applications such as Evolved Packet Core (EPC), voice over LTE (VoLTE), and future 5G core network functions will be cloud enabled: that is, they will have the ability to execute in the SDN/NFV cloud environment. Architecture of 5G. Security and privacy in 5G networks will be characterized by new trust and service delivery models, an evolved threat landscape, and increased privacy concerns. Several layers of the CaaS use open source software which will demand at least quarterly upgrades . The traffic running on these VNFs is typically around 30 percent, ranging from 10 to 50 percent depending on type of VNF. In the telecom environment, it’s not usual for the software vendor to both develop and operate the application; rather, the vendor delivers software to multiple service providers that operate the application. For that reason, 5G systems will be built in the form of programmable platforms that provide functionality on an "as-a-service" basis. 2, 2016, etr-5G-core-vision.pdf, [9] Peter Öhlén et al., "FLEXIBILITY IN 5G TRANSPORT NETWORKS," Ericsson Technology Review, vol. NFV is about virtualizing network functions (by implementing them in software) and the functions that can run on a range of standard hardware. The technique of network slicing allows for the definition of multiple logical networks (or slices) on top of the same physical infrastructure. To conclude, the evolution to 5G standalone will require a cloud-native infrastructure. Virtual and augmented reality enable users to interact with one another as if they are in the same location. This creates an obvious opportunity to generate value from distributed storage and cloud computing towards specific clients and services as well. T-Mobile and Ericsson have worked together to design, build and expand the T-Mobile 5G nationwide network since early in 2018.. Figure 2 illustrates that all applications, including many network applications, are run on top of a cloud with exception of dedicated functions in the access nodes. The second is virtual reality, and will use the 5G eMBB service. The uptake among leaders is increasing quickly. Shopping malls can allow delivery of personalized shopping experiences. [7] International Telecommunications Union Radiocommunication Sector (ITU R), "Framework and overall objectives of the future development of IMT for 2020 and beyond," Recommendation ITU-R M.2083, September 2015, [8] Lars Frid et al., "A vision of the 5G Core," Ericsson Technology Review, vol. At the Ericsson Blog, we provide insight to make complex ideas on technology, innovation and business simple. Deutsche Telekom’s US subsidiary, T-Mobile, has signed a five-year, 5G roll-out contract Ericsson. The 5G transformation has already started with NB-IoT, NFV and management automation, for example. Wireless connectivity is at the center of this technological revolution. A concept known as RAN transport interaction (RTI) introduces coordination between the radio, transport and packet core layers of an operator's mobile network, providing network-wide optimization and service assurance. Compared with previous generations of wireless communications technology, including 4G, the rationale for 5G development is to expand the broadband capability of mobile networks, and to provide specific capabilities not only for consumers but also for various industries and society at large, hence unleashing the potential of the Internet of Things (IoT). Ericsson has adopted a framework of five principles that should be followed when designing cloud-native telecoms applications: Platform agnostic. Advanced antenna technology. Additional key technology components for the 5G radio access solution include: These technology components will not only apply to the new technology part of the 5G wireless access systems but also, to a large extent, to the evolution of LTE. T-Mobile’s 5G buildout also includes 5G standalone architecture, voice over new radio, new radio carrier aggregation, network slicing and multi-user massive MIMO. Others are building larger horizontal telecom clouds, which are able to run multiple VNFs from multiple vendors. A VDC is a collection of virtual machines, virtual network connectivity and associated storage that regards the infrastructure applications as a data center. 5G has broadened this scope to offer a broad range of wireless services delivered to the end user across multiple access platforms and multi-layer networks. The main benefits are: More efficient use of the hardware and a simpler architecture which gives better application performance and is easier to manage. Fig. The resources allocated to a slice can be a mix of centrally located and distributed resources. The four main areas impacted by its adoption are: These four aspects do not exist in isolation. T-Mobile’s 5G buildout also includes 5G Standalone (SA) architecture, voice over new radio (VoNR), New Radio (NR) carrier aggregation, network slicing, and multi-user massive MIMO. The Cisco cloud-to-client approach unifies multivendor mobile solutions into an open, cloud-native architecture so you can deploy services your customers want, when and where they need them. These properties are required to enable new business models that can rapidly generate new revenue … State-optimized design. Regulatory emergency services etc. Exploration of the corresponding business cases – in sectors such as agriculture, automotive, construction, energy, finance, health, manufacturing, media, retail and transport – is therefore critical to ensure that 5G standards ultimately meet the needs of the targeted customer base. Under the deal, Ericsson will expand and enhance T-Mobile’s 5G coverage by supplying equipment, software, and related services from its Ericsson Radio System portfolio, including active and passive antennas, deploy low-band for improved indoor and outdoor coverage. In industry and academia it is generally understood that the success of 5G will depend on a diversity of spectrum assets which span low, medium and high spectrum bands. In particular, a software configurable purpose built architecture [9], [10] and [11] with flexible deployment alternatives will be needed to provide the required overall cost efficiency. To illustrate the flexibility of the 5G system architecture, the realization of three use cases will be considered, each corresponding to a different 5G service. The CNA /CNF needs to work on any service provider CaaS and should only require “vanilla Kubernetes” with no additional plug-ins. (CaaS) platform on top of the exiting VIM (see Figure 4). Ericsson says its Cloud Packet Core (part of the company’s Cloud Core portfolio) helps service providers to smoothly migrate to 5G Core (5GC) stand-alone architecture.. Author’s Note:. complemented by Massive MIMO capacity over mid-bands and high-bands. The move to 5G New Radio (NR) standalone (SA) is necessary to support new advanced 5G services. Automated procedures will be required to cope with this.Fig 2. A network slice is built to address a desired behavior from the network. Network slicing can be used for several purposes: a complete private network, a copy of a public network to test a new service, or a dedicated network for a specific service. New business opportunities are opening up – both for those that have traditionally participated in the value chain, such as telecom operators, and for newcomers from other industries. Thereafter, a newly created slice can be locally managed by the slice owner who will perceive the network slice as his or her own network complete with transport nodes, processing and storage. SK Telecom has selected Ericsson to deliver a Cloud Packet Core for its 5G network. Ericsson highlighted that its technology will help T-Mobile US develop and implement 5G use cases and improve 5G spectral efficiency. This has resulted in six connectivity options for a UE, as shown in Figure … One way to simplify provisioning and control of an application across a VDC will be to define a network slice as a virtual network and let the owner of the slice manage it themselves, within constraints placed by the network provider. The 5G SA architecture will enable new opportunities for innovation for use cases such as augmented- and virtual reality (AR/VR), smart factories, and connected vehicles. It will scale linearly if the infrastructure provides needed resources like CPU, memory, storage and networking. This will allow to optimize the access to applications in terms of capacity and latency, assuming service applications are distributed as well. It is important to note that even though new radio access technologies such as NR will require a new radio bearer, NR and LTE will be fully integrated from a system perspective so NR can both be added as a stand-alone system – for industry applications, for example – or as a natural evolution of the existing wide area LTE networks. Service providers also face two big growth challenges in this journey: how to be more efficient and lower the operational and capital expenditure costs in the whole network when data traffic keeps growing, and how to deal with the increasing network complexity in 5G. While higher network and device complexity is more readily acceptable in critical communication, mMTC will have to address cyber-security assurance with low-complexity devices. A fundamental principle of a cloud-native application is to decompose software into smaller, more manageable pieces, known asaka micro services. Fig 1.
