A 5G network architecture implementing standardized 3GPP interfaces between RAN, UE, and network functions for coordinated service management and user plane traffic handling.

Patentradars sammanfattning

The invention relates to a 5G core network architecture conforming to 3GPP standards, comprising interconnected network functions including RAN (Radio Access Network), UE (User Equipment), AMF (Access and Mobility Management Function), SMF (Session Management Function), UPF (User Plane Function), and AUSF (Authentication Server Function). The system utilizes standardized reference points (N1-N4, N6, N9) and network service interfaces to enable coordinated control plane and user plane operations. Additional specialized functions including NEF, NRF, NSSF, PCF, and UDM provide network exposure, function discovery, network slice selection, policy control, and subscription management respectively.
