It provides encapsulation per PDU session and carries the marking associated with the QoS flows. The UE then connects to the 5G network while maintaining the connectivity to the 4G network. We will discuss Access Network(AN) and Radio Access Network user and control plane protocol in 5G NR. 5G-NR: Protocol Stack 3GPP has released specification 38.300 V1 this month about NR and NG-RAN Overall Description: Stage 2, This standard comes with the detailed descriptions about 5G NR network and Protocol architecture. From 5GC data plane’s perspective on N3 Interface between the gNB and the UPF, the gNB’s 10.20.31.10/24 and the UPF’s 10.20.31/3.24 are the Underlay IP Addresses that transport the Overlay IP datagram between UE and DN. 5G Protocol Stack. The 5G Core (5GC) also updates the IT protocol stack by using Transmission Control Protocol (TCP) as the transport layer protocol in place of Stream Control Transmission Protocol , HTTP/2 as a substitute for Diameter protocol for application layer security, and an added TLS layer for encrypted communication between all network functions. 5G, 4G, 3GPP-LTE . let's have a look at all the layers which are available in E-UTRAN Protocol Stack. The 5G Architecture Working Group as part of the 5GPPP Initiative is looking at capturing novel trends and key technological enablers for the realization of the 5G architecture. 5G protocol stack Developement & testing solutions. 5G NR Control plane Protocol Stack is shown below : When we closely see both LTE & 5G NR protocol stack, we could see many similarities between LTE protocol stack and 5G-NR protocol stack because LTE protocol stack is being taken as the base for the development 5G-NR. NG User-plane(N3) : This is the protocol stack between gNB and UPF. The stack can be licensed both in binary and source form by Silicon designers and chip vendors. The stack also offers LTE Stack functionality. On above image, we can see overview of LTE Protocol Stack. As whown 5G protocol stack consists of OWA layer, network layer, Open transport layer and application layer. Protocol structure of control plane in between UE & MME is shown below.

This is 5G NR Layer 2 and Layer 3 UE Protocol Stack Compliant to 3GPP Release 15 specification. This figure below shows protocol structure in between UE & P-GW user plane. PDCP layer provides services to the upper layers that are, RRC or SDAP and takes few services and inputs from the RLC layer, MAC layer, and PHY layer. The 5G encapsulation layer supports multiplexing the traffic from different PDU sessions over N9 interface (i.e., an interface between different UPFs). Overview. The core technology enabling use cases lies in the implementation of the protocol stack aspect with major features like scheduling, HARQ, Propagation channel models and New Radio protocol stack. To find 3GPP LTE specification, click at the corresponding protocol in the images below. Each part of the stack has its own responsibility. OWA Layer: OWA layer is the short form of Open Wireless Architecture layer. This is 5G NR Layer 2 and Layer 3 UE Protocol Stack Compliant to 3GPP Release 15 specification. UU User-plane : ... this protocol stack is between gNB and AMF. User-plane protocol stack between UE and UPF [3]. It can operate in both SA and NSA mode.

Protocol Stack on different interfaces . Keysight’s 5G UE emulation solution is the only tool that can perform both radio access network (RAN) and core testing for 5G. The below figure presents a control plane protocol’s stack used to establish signalling IPSec SA. Know more. Above Network functions performed by different 5G Access Network entities. Mymo offers 3GPP LTE Release-9 UE FDD and TDD UE Protocol Stack on Arm hardware . Also helps establishment of user-plane tunnels for UE. This stack helps providing access to UE to core network and transports NAS messages. IIT PATNA. It talks about NAS, RRC, PDCP, RLC, MAC, and Physical layer. According to different service requirements, fiber/optic cable availability and network resource allocations, RAN real time and non-real time resources can be deployed on the site or on the access cloud side. A Research and Development Perspective uniquely focuses on the R&D technical design of 5th-generation (5G) networks. The stack also offers LTE Stack functionality. Details for these parts will be described in related pages, now let’s to understand the concept of the protocol stack with an “office condition” example. The functions of the different protocol layers in LTE stack are explained below. 5G NR DESIGN 5G Tech Solutions Pvt Ltd is Developing cost effective SDR based 5G NR Protocol Stack for both gNB and UE and It focuses on Layer 1, Layer 2 and Layer 3 protocols and features. 5G. 5G NR User and control plane protocol stack architecture. Individual protocols within a suite are often designed with a single purpose in mind. It claimed that the HTTP/2 protocol, used for carrying out vital network functions including the … SDAP is the only new layer introduced in 5G. The toolbox also supports interfacing with portions of the RLC and MAC layers, including transport channels and logical channels.
