5G facilitates the development of new business models in all industries. Even now, network slicing will play a critical role in enabling service providers can offer innovative products and services to access new markets and develop their companies. Network slicing is the process of layering numerous virtual networking on the pinnacle of a common network domain, which is a collection of network connections and computational resources. Cloud computing services and Slicing networks allow network operators to enhance network resource utilization and wide scope.

What is network slicing?#

Network slicing is the carriers' best response for building and managing a network that matches and surpasses the evolving needs of a diverse set of users. A sliced network is created by transforming it into a collection of logical networks built on top of shared infrastructure. Each conceptual network is developed to match a specific business function and includes all of the necessary network resources that are configured and linked end-to-end.

Cloud computing services and Network Slicing#

Cloud computing services along with Network Slicing enable new services by combining network and cloud technologies. Cloud Network Slicing is the process of creating discrete end-to-end and on-demand networking abstractions that comprise both Cloud computing services and network services that can be managed, maintained and coordinated separately. Technological advances that potentially benefit from cloud network slicing include critical communications, V2X, Massive IoT, and eMBB (enhanced Mobile Broadband). Distinct services have different needs, such as extremely high throughput, high connection density, or ultra-low latency. According to the established SLA, these must be able to accommodate services with different features.

In Content Delivery Network#

Content delivery network slicing was developed to handle large amounts of content and long-distance transmissions. Content delivery network slicing as a Service (CDNaaS) technology can build virtual machines (VMs) across a network of data centres and give consumers a customised slice of the content delivery network slicing. Caches, transcoders, and streamers deployed in multiple VMs let CDNaaS manage a large number of movies. To produce an efficient slice of Content delivery networks, however, an ideal arrangement of VMs with appropriate flavours for the various pictures is necessary.

5G Edge Network Slicing#

Distinguishable offerings with assured quality of service to varied clients are enabled by 5G Edge network slicing across the shared network infrastructure. It is an end-to-end solution that operates across the Radio Access Network (RAN), the transport layer, the Core network, and the enterprise cloud.

5G service types#

The following 5G service types are the high-level types of network slice architecture which employ slicing for differentiated traffic handling:

Enhanced Mobile Broadband- delivers cellular access to data in three ways: too dense groups of users, extremely maneuverable users, and consumers scattered across large regions. It is based on characteristics such as massive networks of numerous entries, multiple-output (MIMO) transmitters and the mixing of bands beginning with standard 4G wavelengths and reaching into the millimetre band [(Kourtis et al., 2020)].

Massive Machine-Type Communications - services designed to serve a wide range of devices in a compact area while generating little data (tens of bytes/sec) and withstanding significant latency (up to 10 seconds on a round trip). Furthermore, the requirements mandate that data transmission and reception consume little energy so that gadgets can have great battery lifetimes

Ultra-reliable low-latency communications - 5G Edge network is used to provide encrypted systems with latencies of 1 millisecond (ms) and great dependability with minimal, or perhaps even nil, transmission errors. Hardware optimization on MIMO antenna arrays, concurrent manipulation of several bandwidths, package encoding and computing methods, and efficient signal handling is used to achieve this.

Advantages#

Slicing, in conjunction with virtual network activities, is the key to "just right" services for service providers. More capacity to modify affordably gives the following benefits to service providers:

• Reduce the obstacles to testing out new service offers to create new income prospects.

• Increase flexibility by allowing additional types of services to be supplied concurrently because they do not require dedicated or specialised hardware.

• Because all of the physical infrastructures are generic, easier scalability is feasible.

• Better return on the investment is also possible since the capacity to continually test new things allows for the most efficient use of resources.

Conclusion#

As the 5G edge network, Cloud computing services and Content delivery network introduces new technology and opens up new business potential in many industries, businesses are searching for creative solutions to fulfil their demands and capitalize on new chances. Enterprise users expect automated business and operational procedures that begin with buying the service and continue through activation, delivery, and decommissioning. They want services to be delivered quickly and securely. Communication service providers may satisfy all of their corporate clients' demands by slicing their networks.

Introduction#

5G has been substantially implemented, and network operators now have a huge opportunity to monetize new products and services for companies and customers. Network slicing is a critical tool for achieving customer service and assured reliability. Ericsson has created the most comprehensive network slicing platform, comprising 5G Radio Access Networks (RAN) slicing, enabling automatic and quick deployment of services of new and creative 5G use scenarios, using an edge strategy (Subedi et al., 2021). Ericsson 5G Radio Access Networks (RAN) Slicing has indeed been released, and telecom companies are enthusiastic about the possibilities of new 5G services. For mobile network operators, using system control to coordinate bespoke network slices in the personal and commercial market sectors can provide considerable income prospects. Ericsson provides unique procedures to ensure that speed and priority are maintained throughout the network slicing process. Not only do they have operational and business support systems (OSS/BSS), central, wireless, and transit systems in their portfolio, but they also have complete services like Network Support and Service Continuity (Debbabi, Jmal and Chaari Fourati, 2021).

What is 5G Radio Access Networks (RAN) Slicing?#

The concept of network slicing is incomplete without the cooperation of communication service providers. It assures that the 5G Radio Access Networks (RAN) Slicing-enabled services are both dependable and effective. Carriers can't ensure slice efficiency or meet service contracts unless they have network support and service continuity. Furthermore, if carriers fail to secure slice performance or meet the service-level agreement, they may face punishment and the dangers of losing clients (Mathew, 2020). Ericsson 5G Radio Access Networks (RAN) Slicing provides service operators with the unique and assured quality they have to make the most of their 5G resources. The novel approach was created to improve end-to-end network slicing capabilities for radio access network managing resources and coordination. As a consequence, it constantly optimizes radio resource allocation and priority throughout multiple slices to ensure service-level commitments are met. This software solution, which is based on Ericsson radio experience and has a flexible and adaptable design, will help service providers to satisfy expanding needs in sectors such as improved broadband access, network services, mission-critical connectivity, and crucial Internet of Things (IoT) (Li et al., 2017).

Ericsson Network Support#

Across complex ecosystems, such as cloud networks, Network Support enables data-driven fault isolation, which is also necessary to efficiently manage the complexity in [5G systems]. To properly manage the complexity of 5G networks, Ericsson Network Support offers data-driven fault isolation. This guarantees that system faults are quickly resolved and that networks are reliable and robust. Software, equipment, and replacement parts are divided into three categories in Network Support. By properly localizing defects and reducing catastrophic occurrences at the solution level, Ericsson can offer quick timeframes and fewer site visits. Ericsson also supports network slicing by handling multi-vendor ecosystem fault separation and resolving complications among domains (Zhang, 2019). Data-driven fault isolation from Ericsson guarantees the quick resolution of connection problems, as well as strong and effective networks, and includes the following innovative capabilities:

• Ericsson Network Support (Software) provides the carrier's software platform requirements across classic, automated, and cloud-based services in extremely sophisticated network settings. It prevents many mishaps by combining powerful data-driven support approaches with strong domain and networking experience.

• Ericsson Hardware Services provides network hardware support. Connected adds advanced technologies to remote activities, allowing for quicker problem identification and treatment. It integrates network data with past patterns to provide service personnel and network management with relevant real-time information. It is feasible to pinpoint errors with greater precision using remote scans and debugging.

• The Spare Components Management solution gives the operator's field engineers access to the parts they need to keep the network up and running (Subedi et al., 2021). Ericsson will use its broad network of logistical hubs and local parts depots to organize, warehouse, and transport the components.

Ericsson Service Continuity#

To accomplish 5G operational readiness, Service Continuity provides AI-powered, proactive assistance, backed by tight cooperation and Always-On service. Advanced analytical automation and reactive anticipatory insights provided by Ericsson Network Intelligence allow Service Continuity services. It focuses on crucial functionality to help customers reach specified business objectives while streamlining processes and ensuring service continuity (Katsalis et al., 2017). It is based on data-driven analysis and worldwide knowledge that is given directly and consists of two services:

• Ericsson Service Continuity for 5G: Enables the clients' networks to take remedial steps forward in time to prevent end-user disruption, allowing them to move from responsive to proactively network services.

• Ericsson Service Continuity for Private Networks is a smart KPI-based support product for Industry 4.0 systems and services that is targeted to the unique use of Private Networks where excellent performance is critical (Mathew, 2020).

Conclusion for 5G Network Slicing

Network slicing will be one of the most important innovations in the 5G network area, transforming the telecommunications sector. The 5G future necessitates a network that can accommodate a diverse variety of equipment and end customers. Communication service providers must act quickly as the massive network-slicing economic potential emerges (Da Silva et al., 2016). However, deciding where to begin or where to engage is difficult. Ericsson's comprehensive portfolio and end-to-end strategy include Network Support and Service Continuity services. Communication service providers across the world would then "walk the talk" for Network Slicing in the 5G age after incorporating them into their network operations plan.
