3gpp 5gc
The 3rd Generation Partnership Project (3GPP) is a collaboration between telecommunications standards organizations that develops standards for mobile communication technologies, including 3G, 4G, and 5G. 5GC refers to the 5th generation core network, which is a key component of the 5G architecture.
Here's a technical explanation of 3GPP 5GC:
1. Overview:
- Core Network (CN): The 5GC is a part of the mobile network's core infrastructure that provides connectivity and services to users. It is designed to support the enhanced capabilities of 5G compared to previous generations.
2. Key Components:
- AMF (Access and Mobility Management Function):
- Responsible for managing the access and mobility of devices within the 5G network.
- Handles initial registration and mobility procedures.
- SMF (Session Management Function):
- Manages user data sessions and connects to the data network.
- Responsible for setting up, modifying, and releasing data sessions.
- UPF (User Plane Function):
- Handles user data routing and forwarding.
- Plays a crucial role in ensuring low-latency communication for user applications.
- AUSF (Authentication Server Function):
- Responsible for user authentication and authorization.
- Ensures the security and integrity of user communications.
- NSSF (Network Slice Selection Function):
- Manages network slices, which are virtualized, isolated portions of the network optimized for specific use cases or applications.
- UDM (Unified Data Management):
- Manages user-related data, subscription information, and authentication credentials.
