SSC: Session and Service Continuity Mode SSC is used to support multiple continuity requirements. SSC is associated with PDU session and will not change during the lifespan of a PDU session. It means, if a PDU connection is set to SSC mode-x, then it will not …
SMF : Session Management Function SMF is responsible for setting up the connectivity for the UR towards the Data Networks. It also manages user plane for that connectivity. SMF manages the establishment, modification and release of sessions. It allocates IP address to UE depending on the …
In this chapter we shall have a look at the functions of 5G Core Network elements 1. AMF: Access and Mobility Function AMF is similar to MME in 4G AMF interacts with NG RAN using N2 interface AMF interact with UE over N1 interface for authentication, …
In the last chapter we saw Service Based Architecture. In this chapter we shall see reference point architecture. Image below shows the reference point architecture: Here reference points are like we used to have in previous generations 4G, 3G. The interactions between any two network functions …
5G Core Architecture (5GC) is made possible with the help of new technologies such as: 1. Virtualization 2. Cloud Native 3. Containers 4. Micro-services 5. Automation and Orchestration The above technologies are not new, but has been used in IT/DevOps from many years. Now we have …
Before we start looking into the 5G architecture, let us understand some of the terminologies involved: 5GC: 5G Core Network AMF Function: Access and mobility Management UPF: User Plane Function NG-RAN: Next Generation Radio Access Network gNB : Next generation NodeB ng-eNB: Next generation eNB ENDC: …
This article will give you a brief introduction to 5G Architecture and 5G protocol stack. It is not the end-to-end architecture, but an overview. In the up-coming chapters we shall see the end to end architecture and protocol stack functionality. 5G overall architecture: NG-RAN: gNB …
Control Plane Protocol stack User Plane Protocol Stack: Protocol stack layers: Layer Flow: Function of RRC layer: System Information related messages to AS and NAS Paging, RRC connection establishment, maintenance and Release It is also responsible for security function including key management. In carrier aggregation, …
