Изследване на мрежовите функции и референтната архитектура на 5G мобилни системи
A Survey of Network Functions and Reference Architecture of 5G Mobile Systems

Summary/Abstract: The 5G system architecture is designed to be service-based, enabling flexible and efficient service delivery to meet the diverse requirements of different customers, applications and industries. It is based on a set of network functions that are distributed in different locations and interconnected by high-speed, low-latency links. The 5G Reference Architecture is a standardized and modular architecture that defines the core network functions and interfaces required for 5G networks. It is designed to support a wide range of use cases, including enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine-Type Communication (mMTC). A number of key components and functions are included in the 5G reference architecture, such as User Equipment (UE), Access and Mobility Management Function (AMF), Session Management Function (SMF), Policy Control Function (PCF), unified data management (UDM), Network Exposure Function (NEF) and User Plane Function (UPF). These features work together to ensure end-to-end connectivity and service delivery in 5G networks. The 5G architecture is a well-designed and standardized architecture that provides a flexible, scalable and interoperable framework for the development and deployment of 5G services and applications.
