N24: Reference point between the PCF in the visited network and the PCF in the home network. The Figure-1 depicts 5G Protocol Stack consisting of both User Plane and Control Plane protocol layers. Assuming 5G-TMSI = 06666666 (hexadecimal), AMF Pointer=12 (hexadecimal), AMF Set = 001 (hexadecimal), AMF Region = 48 (hexadecimal), the username part of the NAI is encoded as: "tmsi06666666.pt12.set001.region48" The NAI for an N5CW device in a PLMN (either HPLMN or VPLMN) with MNC=012 and MCC=345, to … NR and NG-RAN). 5G New Radio (NR) is the global standard for a unified, more capable 5G wireless air interface. The 5G System architecture consists of the following network functions (NF) majority of which constitute the 5GC: Authentication Server Function (AUSF) Core Access and Mobility Management Function (AMF) Data network (DN), e.g. 5G Stand Alone (SA) Up to now you have been studying 5G EN-DC or Non-Stand Alone. N17: Reference point between AMF and 5G-EIR. C Programming Language ORACLE mysql SQL Server Python Linux Commands Android Jetpack Android. The 5G layer-2 include MAC, RLC and PDCP.The 5G layer-3 is RRC layer as shown in 5G protocol stack. The Mobility Management Functions (MME) from 4G, which implements mobility, access and session management has been decomposed into AMF and SMF. In the 5G Core (5GC) network, the Session Management Function (SMF) interacts with the Access and Mobility Function (AMF) to establish, modify, and release PDU sessions through the Nsmf Service-Based Interface. Although, some types of gNB may connect to the 4G EPC instead of 5G Core. Session Management Function (SMF) Services, 5G Tutorial, 5G. AMF and SMF control functions; NSSF, AMF selection and slice … The 5GC NRM definitions support management of 5GC Network Functions, respective interfaces as well as AMF Set and AMF Region. Inter-AMF N2 Handover. Identified in the specifications of 5G NRM requirements (TS 28.540 and TS 28.542), the NRM of 5G network comprises NRM for the 5G core network (5GC) and NRM for 5G radio access network (i.e. The following features are related to this use case: CHF and PCF Integration for Access and Mobility Procedures. 5G RAN UPF AUSF SMF N1 AMF 5G CORE architecture Functional view –service-based representation UDM PCF NEF AF Nausf Namf Nudm Npcf Nsmf Naf Data Network (e.g. The SMF is primarily responsible for interacting with the decoupled data plane, creating updating and removing Protocol Data Unit (PDU) sessions and managing session context with the User Plane Function (UPF).
