Introduction to 5G Stand Alone
5G StandAlone is a software-defined radio (SDR) technology, which will be a key component of 5G networks and mobile devices. The main aim of 5G StandAlone is to enable quick deployment of various RAN and cellular technologies. 5G StandAlone is a new mobile communication technology that enables 5G communications without the use of an Access Backhaul Network. As it is a global radio-based service that does not require any physical access network (such as an optical fiber or microwave link), 5G Standalone enables coverage and capacity far beyond previous generations of 3GPP specifications. 5G StandAlone is a new mobile communication technology that enables 5G communications without the use of an Access Backhaul Network.

5G StandAlone is the evolution of 3G and 4G technology, adding to it a massive increase in speed and data capacity. 5G StandAlone (SA) will use different frequencies than those used by 4G LTE networks and can be built entirely from scratch, with no dependency on previous generations of LTE networks or infrastructure. 5G SA promises peak gigabit speeds that would be both faster than LTE's peak speeds of one gigabit per second and more affordable for most customers. 5G stand-alone is defined as the ability of a 5G network to function without making use of other mobile technologies like 4G. 5G Standalone is a new form of cellular communication. It is being designed to augment, or even replace, existing networks. When 5G Standalone devices are unconnected to the internet, they can transmit and receive data directly with one another independent of an associated network.
Since most IoT devices are battery-powered, this requirement will help enable more reliable communications and more powerful IoT solutions. 5G standalone is a service, which can be offered in the initial phase of 5G deployment. It offers a user experience that is similar to 4G-LTE services with improved latency and higher peak data rates. 5G StandAlone is a wireless communication technology that builds on the existing 4G LTE standard and offers increased data speeds of up to 20Gbps. It also provides high capacity, scalability, and efficiency that can support industries such as large-scale mobile networks. 5G StandAlone provides the ultimate mobile experience. With a 5G enabled device, users can experience uninterrupted 4K video streaming and seamless downloads at gigabit speeds. The 5G StandAlone is an intelligent edge router. It can aggregate forwarding data plane traffic, control plane signaling, and security context information in one single device. The software environment of this router is built on top of a virtualized Linux operating system that makes it possible to create different partitions on the same hardware platform using containers as a building block (aka "container-based virtualization"). The 5G StandAlone working group develops the requirements and defines a 5G reference architecture. It collaborates with different techniques to develop a standard for 5G in 2020 with speeds up to tens of Gb/s, it is intended to use more spectrum than previous technology generations and provide more meaningful benefits for providing high-speed internet access and autonomous vehicles.
5G SA Call Flow
5G StandAlone Call Flow is a standalone call flow that is used for the communication between a UE and E-UTRAN. This call flow is based on the 3GPP 5G System architecture with baseline technology from Release 15 and subsequent releases. The 5G StandAlone Call Flow describes the sequence of messages which are exchanged between the UE and the network to set up a connection with a target application server. 5G StandAlone is a standalone mode of system operation where 5G NR and 3GPP LTE UE can simultaneously access the same radio resources. The 5G StandAlone (SA) architecture is a new radio access technology (RAT) that can connect to the Internet on its own, with no existing connection. It is designed to provide a mobile broadband experience for 4G and 5G devices, including IoT applications.
In 5G StandAlone, a higher amount of RRM is performed in the eNB, which means that UE needs to report its measurement results only to the eNB. In contrast to RNv2, where eNB and RN are tightly connected, no RN is involved in 5GSa, so the procedures for reporting measurements at different stages of SA protocol are different from networks with RNs. The UE can send 5G SA measurement reports periodically or on-demand. 5G StandAlone (SA) will enable a new business model for telecom operators, in which an operator can use their cellular network to provide internet content services with the help of IP-based connectivity and associated technologies. This article provides a description of 5G StandAlone call flow (SACF).
