Below is a list of some use cases that operators can offer using 5G SA In January 2019, China Central Television completed 4K live broadcasting and 360° virtual reality live with 250Mbps uplink data rate in 5G SA Option 2 network[2].

Charging and Billing Architecture for 5G Network. The 5G NR deployment scenarios are based on multiple RATs (Radio Access Technologies) and type of cores (EPC or 5G CN) used for signaling. The 5G Core Network has been designed around services that are invoked using a standard API. Abstract. SA 5G NR is being specified by 3GPP and utilizes the new 5G next-generation core network architecture (5G NGC). A look at a generalized 5G architecture is shown in the figure below. The standalone (SA) mode of 5G NR refers to using 5G cells for both signalling and information transfer. The Snapdragon X55 5G Modem-RF System supports virtually any combination of spectrum bands and/or modes: 5G mmWave and sub-6 GHz, standalone and non-standalone modes, TDD and FDD, spectrum sharing, LTE and legacy modes (3G, 2G). These values achieved by 5G SA architecture allow the system to support new mission-critical use cases that previous mobile generations could not. A solution that combines 3GPP network functions from EPC and 5GC architectures into a common cloud native software platform that supports 5G NR Stand-Alone (SA) and Non-Standalone (NSA), 4G, 3G and 2G accesses technologies. Based on the services requirements elaborated by SA WG1, SA WG2 identifies the main functions and entities of the network, how these entities are linked to each other and the information they exchange. This is designed to enable OEMs to bring blazing fast connected devices to global networks in nearly any form factor. 5G PPP Architecture Working Group View on 5G Architecture Version for public consultation, updated version available on July 1st 2016 Page 9 / 60 telecommunication operators. 5G is the fifth generation wireless technology and also known as the fastest, most reliable and lowest latency technology ever. 5G scenarios in 3GPP NR & NextGenCore (5/6) 7 LTE NR EPC NextGen Core 7) Non-Standalone/”LTE assisted”, NGCN connected 5G architecture options | RAN/SA meeting, June 2016 RP-161266 15.06.2016 LTE NR EPC NextGen Core 7a) Non-Standalone/”LTE assisted”, NGCN connected „1a-like“ Machine-type communication, enabled by 5G, is widely anticipated to become the strategic difference and unique selling point of 5G in the long run. With service providers’ needs and concerns in mind we have developed the dual-mode 5G Core solution. Yet, there are multiple scenarios determining how 5G rollouts will take place, including use of a Stand Alone (SA) or Non-Stand Alone (NSA) architecture. Only the 5G NR terminal needs to be compatible with DSS. This page describes 5G NR deployment scenarios or modes.They are NSA (Non-Standalone), SA (Standalone), Homogeneous, Heterogeneous modes. 5G NR Deployment Scenarios or modes-NSA, SA, Homogeneous, Heterogeneous. A telecommunication operator may also have the role of a service provider as it the case today. There are three physical components: Radio Access Network (RAN). Architecture of 5G As shown in the following image, the system model of 5G is entirely IP based model designed for the wireless and mobile networks. SA 5G NR is expected to be completed in June 2018. SA Working Group 2 (SA2) within the TSG SA studies architecture and main functions of the 5G network system under the study item of Next Generation system (NextGen). The system comprising of a main user terminal and then a number of independent and autonomous radio access technologies. 5G networks will serve as critical infrastructures to facilitate the digitization, automation and connectivity to machines, robots and transport solutions etc. The 5G transformation has reached a critical phase. This is the wireless network part of the network that connects to mobile devices.
