The Radio Access Network - consists of various types of facilities including small cells, towers, masts and dedicated in-building and home systems that connect mobile users and wireless devices to the main core network. The new 5GS network architecture enables a wider eco-system for service innovation. The list of capabilities goes on, but here are a few others: Is 5G Core and NR SA future proof? Redefine customer experience in real time, Service exposure and traffic steering functionalities introduced in the 5G Core will provide additional tools for service differentiation, Enhanced QoS model that is more flexible and granular than in 4G networks and that will allow multiple services (QoS flows) per PDU Session, Security is improved to secure end-to-end communication with enhanced key handling and a unified authentication model for applications and network users, Service differentiation per geographical area is also increased which is, for instance, useful to control access to FWA services or other localized services. The two gateways in the 4G EPC, S-GW and P-GW, have both been combined and split into control plane and user plane functions, and absorbed into the SMF and the UPF. In many countries the initial frequency bands for 5G are below 6 GHz (in many cases in the 3.3-3.8 GHz bands) and similar frequencies to existing mobile and Wi-Fi networks. New and Emerging technologies such as virtual and augmented reality will be accessible by everyone. The possibility to add new network functionalities, introduce in a highly agile way, scale capacity very quickly and run in-service software upgrades, will make it possible to create and deploy new services in hours. Please sign up for email updates on your favorite topics. When several experts in the telecom industry got together to define the new 5G Core architecture they took on the challenge of creating something to address the needs of not just today, but the future – raising mobile communications to unprecedented levels and making it possible to digitalize entire societies. The Network Slice Selection Function (NSSF) maintains a list of the network slice instances defined by the operator, including their definitions, such as required resources. Additional mobile spectrum above 6 GHz, including the 26-28 GHz bands often referred to as millimeter (mm) Wave, will provide significantly more capacity compared to the current mobile technologies. There are three major categories of use case for 5G: For communities, 5G will enable the connection of billions of devices for our smart cities, smart schools and smart homes, smart and safer vehicles, enhance health care and education, and provide a safer and more efficient place to live. The User Plane Function (UPF) combines the user traffic transport functions previously performed by the S-GW and P-GW in the 4G EPC. 5G network architecture illustrating 5G and 4G working together, with central and local servers providing faster content to users and low latency applications. Businesses will operate and make key decisions driven by data, innovate in agriculture, smart farms and manufacturing, paving the way for cost savings, better customer experience and long term growth. A mobile network has two main components, the ‘Radio Access Network’ and the ‘Core Network’. The 5GC Session Management Function (SMF) provides the session management functionality of the 4G MME and additionally combines some control plane functions of the S-GW and P-GW. How does 5G work? Paul Shepherd is a Senior Consultant for Award Solutions. Some functions have been split into multiple sperate components, while some functions have been combined. Network slicing is a new capability of the 5G network. The overall physical size of the 5G base station antenna is expected to be similar to a 4G base station antenna. Example of a local server in a 5G network providing faster connection and lower response times. 5G Network - Mobile Network Architecture Significant changes in both the Core Network (Core) and Radio Access Network (RAN) are required to deliver low latency. Online Course. Where appropriate, these new network elements are compared to their equivalents in the 4G Evolved Packet Core (EPC). A UE may be configured with a list of subscribed network slices and can request these during the registration procedure. We help companies tackle new technologies by equipping their teams with knowledge and skills. Learn about the architecture for the 5G packet core, including a description of the functions of the network elements. He has successfully developed and delivered emerging technology training to leading service providers worldwide. What will 5G enable? Award Solutions is the trusted training partner to the world's best networks. 5G working with 4G How does 5G deliver continuous connection, greater capacity, and faster speed and response times? Published on: 9/10/2018Author: Paul Shepherd, Senior Consultant, Award Solutions. 4G sector base station and 5G base station with a new multi element massive MIMO antenna array. LTE refers to 'Long Term Evolution', and the architecture of the LTE network is as following, LTE Network Architecture. The new Network Slice Selection Functions (NSSF) will allow an improved isolation and separation of concern between slices, which is a critical requirement for some business segments. The additional spectrum and greater capacity will enable more users, more data and faster connections. As shown in the diagram, the MME functions have essentially been distributed among the AMF, the SMF, and the AUSF. Mobile spectrum showing the radio frequency range from 3-100 GHz with new 5G spectrum above 6GHz. The 4G network architecture was defined to meet the mobile network needs that existed at that time, but today it presents certain limitations. 3G networks had a typical response time of 100 milliseconds, 4G is around 30 milliseconds and 5G will be as low as 1 millisecond. The SMF allocates IP addresses to the UE. The 4G network architecture was defined to meet the mobile network needs that existed at that time, but today it presents certain limitations. But best of all, it’s available now and in the next few years it will transform businesses and societies. The simple answer to this question is: without the 5G Core, advanced 5G use cases such as multiplayer augmented reality gaming, will never materialize. 5G has been designed to meet the very large growth in data and connectivity of today’s modern society, the internet of things with billions of connected devices, and tomorrow’s innovations.
