5G RAN Paging for UE in the RRC Inactive State

› Here I try to depict how a UE in the RRC Inactive state can be paged when the downlink user plane data is arrived at the UFP(User Plane Function) and then the suspended radio connections (DRBs and SRBs) are activated by UE upon receiving RRCResume message from the gNB.
