sdap layer in 5g

The 5G (Fifth Generation) mobile network architecture is designed to provide significantly faster data speeds, lower latency, and improved connectivity compared to previous generations (4G/LTE). The architecture is defined by the 3rd Generation Partnership Project (3GPP). The key components of the 5G architecture include:

1. User Equipment (UE): This refers to the end-user devices, such as smartphones, tablets, or IoT devices.
2. Radio Access Network (RAN): This includes the radio base stations, antennas, and other components that facilitate communication between the UE and the core network. In 5G, the RAN is divided into the gNB (Next-Generation NodeB) and ng-eNB (Next Generation evolved NodeB).
3. Core Network (CN): The core network is responsible for managing and directing communication within the overall network. It includes various network functions, and the key components in the 5G core network are:a. AMF (Access and Mobility Management Function): Manages access and mobility-related functions for the UE.b. SMF (Session Management Function): Handles session-related information and is responsible for setting up and releasing data sessions.c. UPF (User Plane Function): Manages the user plane data, responsible for packet forwarding, and performs tasks such as traffic policing and shaping.d. UDM (Unified Data Management): Handles subscriber data management, including authentication and authorization.e. AUSF (Authentication Server Function): Responsible for authentication.f. NSSF (Network Slice Selection Function): Manages network slicing, which allows the creation of virtual networks tailored to specific services or requirements.g. NEF (Network Exposure Function): Provides exposure of network capabilities to external applications.
