Edge Components

Main components of our edge

MME(Mobility Management Entity)

  • Authentication and Security: MME handles user authentication and security key management in a mobile network, ensuring secure connections.
  • Mobility Handling: It manages mobility-related functions, such as tracking and paging of mobile devices as they move through the network.
  • Bearer Management: MME is responsible for creating, modifying, and releasing bearers for user data traffic.
  • Fault Tolerance: Redundancy and failover capabilities are often built-in to ensure network reliability.

UPF (User Plane Function)

  • Data Forwarding: UPF handles the forwarding of user data packets, ensuring efficient routing and low-latency communication.
  • Edge Computing: UPF can support edge computing capabilities, allowing the processing of data closer to the end-user for reduced latency.
  • Scalability: UPF can scale horizontally to handle increased data traffic loads.
  • Quality of Service (QoS): It supports QoS mechanisms to prioritize and manage different types of traffic, essential for services like video streaming and real-time communication.

SPGW-C(Serving Gateway Control Plane)

  • Control Plane Functions: SPGW-C manages control plane signaling for user data sessions.
  • Session Management: It establishes and releases data sessions for mobile users, ensuring seamless connectivity.
  • Policy Enforcement: SPGW-C enforces network policies and performs session-specific functions, such as IP address allocation.
  • High Availability: Redundancy and high availability features are often included for network reliability.

HSS(Home Subscriber Server)

  • The HSS is the central database that contains information about all the network operator's subscribers.
  • Subscriber related information held by the HSS includes user identification, security, location and subscription profile.
  • It stores subscriber information (such as service profiles, authentication ciphering, subscription state, device details, user's physical location, and more), performs user authentication and authorization
