Emblasoft offers a flexible solution. But its a challenge to recreate real-world network traffic volumes and types. NFs and NF services can communicate directly, referred to as Direct Communication, or indirectly via the SCP, referred to as Indirect Communication. Legacy Core Networks have been deployed using separate hardware for each Network Element. 1699 0 obj What kind of throughput will be required? Source: 3GPP Branch connectivity in a compact, affordable, all-in-one solution, Herding Cats: Leveraging LTE and Preparing for 5G. In the 4G network architecture, User Equipment (UE) like smartphones or cellular devices, connects over the LTE Radio Access Network (E-UTRAN) to the Evolved Packet Core (EPC) and then further to External Networks, like the Internet. The services are specified for the Network Function providing them, instead of each pair providing and consuming Network. Support P-CSCF discovery for IMS services. 0000005721 00000 n In short, Emblasoft ensures the testing of two of the most important interfaces in 4G and 5G networks N3 and S1-U, respectively with the ability to measure and test a wide range of parameters and characteristics from emulated traffic that accurately reflects real-world traffic types and volumes. Greater capacity, fueling a massive amount of IoT devices per square kilometer. each Network Function is a service provider. Stateless data concerns the size and volume of the data, rather than the content itself for example, from IoT sources such as a car uploading data about its journey. Network Repository Function (NRF) is used for service discovering of network functions or simply say it allows every network function to discover the service list offered by other network functions. %%EOF Appearing in the second specification iteration of 5G, or release 16 in 3GPP parlance, the Service Communication Proxy (SCP) was defined within TS23.501 System architecture for the 5G System. We will have SCP description below. To prepare for the 3G sunset, it's important to understand where the industry is going in order to plan your migration. Network Exposure Function (NEF) supports exposure of network functions capabilities in 5G system to external network functions such as 3rd party, Application Functions. It can be dedicated for a network function (e.g. CHarging Function (CHF) is not described in this page, you can find specifications in 3GPP TS 32.240. Digi EX50 is Digis next-generation enterprise-grade 5G Peruse our library of thought leadership and technical content on all things 5G. (Note that 2G and 3G networks are being sunsetto make room for 5G deployment. Service Communication Proxy (SCP) has following functionalities: Message forwarding and routing to destination NF/NF service. centralized location or distributed (remote) location. For autonomous vehicles and intelligent transportation systems (ITS) applications, the devices and connectivity must be optimized for speed. Unified Data Repository (UDR) is another type of storage which stores data belongs to UDM, PCF or NEF and others. This will bring the low latency and ability to connect with massive numbers of IoT devices that are among the primary advantages of 5G. When operating in this mode, a device will first connect to the 4G LTE network, and if 5G is available, the device will be able to use it for additional bandwidth. 0000211860 00000 n The PCF is analogous to the PCRF in EPC architectures. Indirect Communication, lets have a bit more information for this function. User Plane Function (UPF) is responsible for routing and forwarding user plane packets Access Node (gNB) and external data network. Data Network (DN), e.g. Emblasoft can test both types of data at the same time, too. Where will your application be deployed? 0000000016 00000 n Today, 5G networks are actively being deployed, and combined with other technology advances and trends, including the IoT, edge What is 5G? Because high frequencies cannot easily move through obstacles, high-band 5G is short range by nature. Emblasoft can emulate real content through VMI / hardware with high volumes of traffic reflecting the real demands of the network. In this section we will provide a 5G core architecture overview and describe the 5G core components. Also 3rd party applications might be untrusted and NEF can be required. Systems integrators, and those developing and deploying 5G applications for the verticals weve discussed, will find that it is important to consider trade-offs. External exposure can be categorized as Monitoring capability, Provisioning capability, Policy/Charging capability and Analytics reporting capability. The Provisioning capability is for allowing external party to provision of information which can be used for the UE in 5G System. The Service Based architecture represents a move towards a cloud implementation of the Core Network. The NWDAF includes the following functionality: Support data collection from NFs and AFs; Support analytics information provisioning to NFs, AF. These range from 24 GHz to approximately 100 GHz. 0000004286 00000 n Performance of low-band 5G is therefore similar to 4G LTE, and supports use for 5G devices on the market today. The 5G core network supports the Virtualization of software functions to use NFVI in design 5G Networks, including MEC infrastructure. The 5G core network, which enables the advanced functionality of 5G networks, is one of three primary components of the 5G System, also known as 5GS (source). NF services may communicate directly between NF Service consumers and NF Service Producers, or indirectly via an SCP. The Access and Mobility Management Function (AMF) instance serving a piece of User Equipment (UE) is common to all Network Slices that UE is a member of. The UPF has some Deep Packet Inspection (DPI) capabilities and so carries both stateful and stateless traffic. The SCP is not required to make a 5G SBA work but is required to make it work in a highly distributed multi-access edge compute cloud environment. The 5G N3 interface performs the role of conveying user data from the RAN to the User Plane Function, making it possible to create both low- and high-latency services. Required fields are marked *. Some key principles and concept are to: 3GPP specified and presents both versions of 5G system architectures: A reference point representation, shows the interaction exist between network elements by point-to-point reference point. Cellular networks are changing, and some are sunsetting. All network functions register the services they offer with the NRF using service registration procedure, and later they use the NRF as a database to discover the services offered by other Network with service discovery and service authorization procedure. Connect your devices with versatile modules and powerful single-board computers designed for rapid deployment and scalability. The NRF supports service discovery, by receipt of Discovery Requests from NF instances and details which NF instances support specific services. That is why this architecture is also called 5G core Service-Based Architecture (SBA). Network Data Analytics Function (NWDAF) represents operator managed network analytics logical function. 5 Factors to Guide Your Preparation for 5G, 4G LTE (Long Term Evolution) has a long life. The 5G System Architecture contains the following reference points: Authentication Server Function (AUSF) is responsible to handle authentication requests for both, 3GPP access and untrusted non-3GPP access. Session Management Function (SMF) includes the following functionality: Session Management e.g. 0000065372 00000 n to enable flexible and efficient network slicing. Currently, however, the Service-Based Architecture employs a centralized discovery framework that leverages a NF Repository Function (NRF). Network slicing is a fundamental new capability of 5G infrastructures, bringing a high degree of deployment flexibility and efficient resource utilization when deploying diverse network services and applications. The Monitoring capability is for monitoring of specific event for UE in 5G System and making such monitoring events information available for external exposure via the NEF. The naming for service based interface includes network function name with the letter N, e.g. A 5G System (5GS) consists of User Equipment (UE), 5G Base station (gNB), 5G and a 5G Core Network (5GC) as illustrated in following Figure 1. The 5G core uses a cloud-aligned service-based architecture (SBA) to support authentication, security, session management and aggregation of traffic from connected devices, all of which requires the complex interconnection of network functions, as shown in the 5G core diagram. Optimal use cases include 5G cellular telecommunications in the 24- to 39-GHz bands, police radar in the Ka-band (33.4- to 36.0-GHz), scanners in airport security, short-range radar in military vehicles and automated weapons on naval ships to detect and take down missiles. Specialized on Radio Domain and Customer Experience (Cx, Probing solution - SQM, CEM). The S1-U interface, meanwhile, performs a similar role in 4G networks by connecting the eNodeB to the Serving Gateway (SGW) and transmitting user data on to the Packet Gateway and the internet. The NRF maintains a record of available NF instances and their supported services. 1699 36 Based on the service requested by the UE, the AMF selects the respective Session Management Function (SMF) for managing the user session.

The following 5G network topology diagram shows the key components of a 5G core network: Applications that are optimized for mmWave will not operate as expected within buildings and when extended range is required. trailer <>stream Serverless Python Bot Using Azure Function, Filesystem Layouts Supported by Kubernetes, APIM v4.1.0 revoke the token when invoking an API, Kafka Setup in Kubernetes Using Strimzi K8s operatorPart 1, HA Kubernetes RKE2 with Kube-VIP and Rancher. The Network Slice instance selection is triggered by the first AMF that receives a UE registration request, which the retrieves the permitted slices from the Unified Data Management (UDM) element and then requests an appropriate Network Slice Instance of the NSSF. Application Function (AF) is a control plane function within 5G core network, provides application services to the subscriber. Here is my brief bio: 16 years professional experience in telecom industry, with multiple vendors and operators: Vodafone, T-Mobile, Rakuten Mobile, Nokia, Huawei and others. Typical 5G system network architecture consists of Core Network, Access Network and User Equipment, this part is a bit like previous generations which we already have such domains. We already paced to a new era with 5G which is completely different than legacy technologies. The other two components are 5G Access network (5G-AN) and User Equipment (UE). Part 2, Who Will Adopt 5G Technology, and When? 0000004233 00000 n 0000188283 00000 n The Service Based architecture is applicable to the control plane, and Reference Point architecture is used for the user plane of the 5G Core Network. Please contact us at support@cubro.com for any further questions or more details regarding our solution. Not only that, we can also handle both N3 and S1-U at the same time, enabling different generations of technology to be tested in parallel ensuring validation for handovers between the two, for example. only for UDM) or can be shared between multiple network functions. The SCP address may be locally configured in NF Service consumer. 0000005554 00000 n 0000006810 00000 n N2 is the logical reference point between gNB and AMF, whereas N3 is a reference point between gNB and UPF. Each Network Function service exposes its functionality through a Service Based Interface (SBI), which employs a well-defined REST interface using HTTP/2. Each point-to-point interface has specified certain signalling protocols and procedures. 0000008137 00000 n N11 interface between AMF and SMF. The Policy Control Function (PCF) supports a unified policy framework, within the 5G infrastructure, for governing network behavior. The earliest uses of 5G technology will not be exclusively 5G but will appear in applications where connectivity is shared with existing 4G LTE in what is called non-standalone (NSA) mode. <<3438F10002B2B2110A0050560977FD7F>]/Prev 1281622/XRefStm 2215>> a Mobile Network Operator (MNO) can add more user plane functions without adding more control plane and vice versa depending on deployment strategies. Video applications such as medical imaging can ultimately take full advantage of the massive amounts of data that 5G networks can support. The 3GPP defines a Service-Based Architecture (SBA), whereby the control plane functionality and common data repositories of a 5G network are delivered by way of a set of interconnected Network Functions (NFs), each with authorization to access each others services. Enhanced Mobile Broadband (eMBB), Ultra-ReliableLow Latency Communication (URLCC) and Massive Machine Type Communication (mMTC). 0000065301 00000 n 5G System Service Based architecture is illustrated in Figure 4. Network functions may have their own UDSF or it can be common. 0000003696 00000 n The Network Repository Function (NRF) is the main network function in service based architecture and plays a key role. %PDF-1.5 % The User Plane Function (UPF) is the fundamental component of the 5G core infrastructure that enables such low-latency edge computing although it can also sit in the core through the CUPS architecture, which defines the separation of the two data planes. The interface conveys user data from the RAN to the UPF for processing the distance the UPF sits from the edge of the network depends on the latency and performance requirements of the application, for example low-grade IoT data versus a self-driving car. The 5G System architecture shall leverage service-based interactions between Control Plane (CP) Network Functions where identified. Assuming the role of either service consumer or service producer, Network Functions are self-contained, independent and reusable. 0 Enter Control and User Plane Separation (CUPS) and Multi-Access Edge Computing, which brings computing, storage and management closer to the edge of the cloud and nearer to the devices that need it. It handles downlink packet buffering and downlink data notification triggering. But today we will not talk about delivered services by 5G, instead of that we will briefly present the heart of the technology which is 5GC or in other word 5G Core Network. Separate the User Plane (UP) functions from the Control Plane (CP) functions, allowing independent scalability, evolution and flexible deployments e.g. Policy Control Function (PCF) provides policy rules to Control Plane functions (e.g. See how long 2G, 3G and 4G will be available. What Can 5G Do For Business: Enterprise, Industry and Transportation. 5G was designed from the ground up, and network functions are split up by service. The following diagram illustrates the migration over time, as well as Digi's 5G product plans. 1734 0 obj Let's connect on LinkedIn, in a professional networking platform. This representation also includes point-to-point reference points where necessary. The Policy/Charging capability is for handling QoS and charging policy for the UE based on the request from external party. Session Establishment, modify and release, including tunnel maintain between UPF and AN node. each Network Function is a service provider. This band uses spectrum that is available and in use today for 4G LTE, essentially providing an LTE 5g architecture for 5G devices that are ready now. Today 5G Core Networks use cloud-native network functions (CNF). Together with the NRF, the SCP forms the hierarchical 5G Service Mesh. Of course, 5G and the IoT has also opened the competitive market for new applications and entrants, meaning that MNOs need to be able design, test and validate new services and applications quickly and reliably both to remain relevant and to support demanding applications. Storage and retrieval of structured data for exposure. Stateful traffic generally represents real-time services such as RCS messaging, video streaming or conversational video, web browsing, and so on. Its the sort of function that is born of necessity.

The introduction of 5G will transform the role that communications technology plays in society. AMF) within the Control Plane enables other authorized network functions to access their services. For example, here are examples of some of the key considerations: For 5G to deliver its full vision, the network infrastructure needs to evolve as well. This allows the SCP to become the delegated discovery point in a data center, offloading the NRF from the numerous distributed services meshes that would ultimately make-up a network operators infrastructure. 0000007357 00000 n When public LTE or Wi-Fi networks arent available or practical, a dedicated private network may be the answer. Unlike previous generations of mobile networks which were designed for enhanced voice (2G), data messaging and mobile broadband (4G) 5G goes way beyond anything before. 5G is the next generation network technology, promising exponentially higher bandwidth along with lower latency to support the How to Stay Ahead of the 3G Network Sunset. xref 0000002962 00000 n 0000006491 00000 n EPS Session Management Timers Network side, EPS Mobility Management Timers Network side, 5G Technology Overview and New Radio (2018), How to import site database to Actix Analyzer, How to create a customized window in TEMS Investigation, Properties of Layer 3 window in TEMS Investigation, Smart Home solution with Internet of Things. In service-based system architecture each network functions are connected to a bus and connection labeled like: Namf, Nsmf, Nudm etc. The interface naming for the Reference point is given as a number with the letter N like N2, N3 or N4. What is Service Based Architecture for 5G System, In Service based architecture, the set of Network Elements (NEs) are replaced with a set of Network Functions (NFs). Identification of a Network Slice is via the Single Network Slice Selection Assistance Information (S-NSSAI). However, in this case, the processing takes place in the core, so there is a limit to the performance that can be achieved for user applications. The 5G System architecture consists of the following network functions (NF). In 5GS architecture, the 5GC is located at heart and enables the 5G RAN to support 3GPP defined three use cases, i.e. Maintain a constant flow of data between your devices with secure cellular routers and gateways built for networks of various speeds and sizes. 5G will enable ultra-reliable, low-latency applications, and support millions of sensors and devices within the Internet of Things (IoT), which together will bring new use cases to enable smart cities, autonomous vehicles, smart logistics, smart energy, and so on.
