In SA architecture we have 3 implementation options. Option 3: EPC and an LTE eNB acting as master and en-gNB NR acting as secondary. In SBA network can be deployed as fully distributed, fully redundant, stateless, and fully scalable. In this section, I’d like to touch upon the 5G network functions (NFs) related to 5GC. Marcin was a Work Package leader in 5GNOW, a EU-funded research project aiming at radio interface design for 5G. In 4G EPC, S-GW and P-GW functionalities have both been merged and divided into separate control plane and user plane functions in 5GC, SMF and UPF are the elements which perform the same functionalities. The course covers 5G technologies in full depth and breadth and includes topics like software based architecture, Network Slicing, Virtualised Network Core Functions, User Plane splitting, Full layered cybersecurity and 5G applications that will revolutionize the form and operation of mobile network … We can achieve this control plan and user plan separation by implementing NFVI (Network Function Virtualization) and SDN. It offers many functions including network slicing to serve vivid customer requirements. [2] M. Rahnema, M. Dryjanski, “From LTE to LTE-Advanced Pro and 5G”, Artech House, 2017. Service base architecture of 5g core Network will support virtualization deployment. The system comprising of a main user terminal and … 2. 3GPP is a standard body that is defining both a new 5G core network (5GC) and a new radio access technology called 5G “New Radio” (NR). The N26 interface has been introduced to be an inter-CN interface between the Mobility Management Entity (MME) in the LTE core network and 5GS AMF in order to enable interworking between EPC and the NG core. There are several options available to integrate between different generations of access network technology with the core network. 1. M. Rahnema, M. Dryjanski, “From LTE to LTE-Advanced Pro and 5G”, Artech House, 2017. The architecture and detailed design of the 5G new radio The implementation of HTTP/2 on the service-based interfaces of the 5G core The signalling procedures that govern the end-to-end-operation of the system The new features that are introduced in Releases 16 and 17. With such requirements in mind, the 3GPP has kept the basic idea of having a flat architecture, where the Control Plane (CP) functions are separated from the User Plane (UP), in order to make them scaling independent — allowing operators to use this functional split for dimensioning, deploying, and adapting the network to their needs. Option 2: access to 5GC and NR gNB and. But, unlike EPC functions, AMF, SMF, and UPF should be access independent. This representation also includes point-to-point reference points between the NFs where necessary (see lower part of Fig. Responsible for interconnect between RAN and EPC. A key Network Function (NF) of SBA is the Network Repository Function … The 5G System architecture consists of the following main NFs, which constitute the 5GC: Inter-working between 4G and 5G play a very important role in early deployment of a 5G system, which will rely on LTE to be the anchor or underlying system. It is responsible for AMF selection when UE is trying to register from non-trusted access network like WiFi. So basically in existing LTE … 5GC 5G Core 5G-MoNArch 5G Mobile Network Architecture for diverse services, use cases, and applications in 5G and beyond 5G-PICTURE 5G Programmable Infrastructure Converging disaggregated neTwork and compUte Resources 5G PPP 5G Infrastructure Public Private Partnership 5GS 5G … In the SA model, only one radio access technology, either 5G NR or LTE radio cells, and the core networks operate alone. 5G Core Service-Based Architecture (SBA) Service-Based Architecture for core 5G networks is defined in 3GPP Technical Specification (TS) 23.501 — “System Architecture for the 5G … It is used to manage the mobility, security and session of UE. The new 5G core, as defined by 3GPP, utilizes cloud-aligned, service-based architecture (SBA) that spans across all 5G … In the previous section covering 5G CN functions, we used the service-based representation to explain the roles played by the different network functions based on their service.
