The fundamental idea with Edge Computing is to allow services and applications to be hosted and executed “close” to the subscriber/user/client. Edge Computing in general results in lower end-to-end latencies and lower load in transport networks.

The Edge Computing in 5G course describes various ways and technologies to implement and/or facilitate Edge Computing in the 5G System. Both 3GPP and ETSI (European Telecommunication Standardization Institute) have done standardization work aiming at implementing, facilitating and/or integrating Edge Computing in the 5G System. The course accounts for these standardization efforts and their relationship to each other.

Important note: The course is not about the possible edge applications themselves, e.g. V2X, AR/VR or manufacturing. The course is about how the 5G System can support these applications being deployed at the edge of the network.

Note: The course is under development and the content may be subject to change.

Course Outline

5G System – a Short Repetition
  • Short repetition of the 5G architecture, Network Functions (NFs), Data Networks (DNs), PDU Sessions etc
  • Application Server (AS) vs Application Function
  • PDU Session Anchor (PSA) and Data Network Access Identifier (DNAI)
The Service Based Architecture
  • Communication between NFs in the Service Based Architecture
  • Service Based Interfaces (SBI) and APIs
  • NF Services and Service Operations
  • NF Service Consumer vs NF Service Producer
PDU Session Establishment and Modification
  • Procedures at PDU Session Establishment and Modification
  • Role of UL CL (Uplink Classifier) or BP (Branching Point)
  • Reasons for modification
  • Session and Service Continuity (SSC) Modes
  • NF Services provided by SMF (Session Management Function)
Network Exposure and AF Influence on Traffic Routing
  • Role of the Network Exposure Function (NEF)
  • NF Services provided by NEF and AF
  • Information exchange between NEF and AF
  • The N33 reference point
  • Central vs Local part of Data Network
