5G? - Answers

The 3GPP defined 5G network architecture enables deployment using NFV and SDN.The 5G Architecture consists of two parts- The 5G Next Generation Radio Access Network (NG-RAN) and 5G Core Network (5GC).The 5G NG-RAN consists of gNB and/or eNBs connected to the 5GC with an open interface. gNB and eNBs in 5G RAN are interconnected through the Xn interface. 5G enabled devices access 5G NG-RAN via the New Radio (NR) access air interface.Some of the key logical Functional nodes in the 5G Core Network are shown here. These are:1.The Access and Mobility Management function (AMF)2.The Session Management Function (SMF)3.The User Plane Function (UPF)4.The Policy and Charging Function (PCF)5.Unified Data Management (UDM)6.The Authentication Server Function (AUSF)
