name: DRNC
full_form: Drift RNC
context: state and starts to consume radio resources from one cell controlled by the DRNC, MBMS UE Linking in the DRNC is performed via UE dedicated Iur procedures. After that the DRNC shall update the MBMS Service context in the DRNC at every intra-DRNC cell change without the need to receive UE Link from the SRNC. 3. If the UE is in CELL_DCH and CELL_FACH state and there is no dedicated RNL signalling activity ongoing for this UE and UE Linking is performed in the SRNC for an MBMS Service, MBMS UE Linking in the DRNC is performed via the MBMS Attach procedure. 4 If the UE is in CELL_PCH and moves to a cell within the DRNC area for the first time, the MBMS UE Linking in the DRNC is performed. The cell the UE moved to is indicated to the DRNC. After that at every intra-DRNC cell change the DRNC shall update the MBMS Service context in the DRNC without the need to receive UE Link from the SRNC. 5. If the UE is in CELL_PCH and there is no mobility related signalling activity ongoing for this UE
description: The Drift RNC (DRNC) is a network function responsible for managing radio resources and handling MBMS (Multimedia Broadcast Multicast Service) UE linking and de-linking procedures within its controlled cells. It updates the MBMS service context at every intra-DRNC cell change without requiring UE Link from the SRNC.
explanation: The DRNC is classified as a Network Function because it performs essential network control tasks such as managing radio resources, handling user equipment (UE) association and disassociation for MBMS services, and maintaining the service context within its assigned cells.
