F1 interface 3gpp. The f1 interface provides means for interconnecting a gnb cu and a gnb du of a gnb within an ng ran or for interconnecting a gnb cu and a gnb du of an en gnb within an e utran. It covers functions and locations of these 5g nr interfaces used between 5g ran and 5gc. The present document is an introduction to the 3gpp ts 3847x series of technical specifications that define the f1 interface.
Messaging over f1 interface include control plane f1 c management traffic and user plane f1 u. It includes xn interface ng interface e1 interface f1 interface and f2 interface used in 5g nr new radio network architecture. User equipment ue conformance specification.
The ng ran consists of a set of gnbs connected to the 5gc 5g core network via the ng interface. It is from 9. X2 inter base stations interface fig4 1 1 in 3gpp ts 36800 june 2017 release 15.
The f1 interface 5 6 between du and cu could also be protected by ndsip 11 12. 5g nr overall architecture is shown in the following figure 2. Specification has been created for release rel 15.
