RNA

Technical Explanation

To avoid excessive signaling during mobility, the gNodeB assigns an RNA to the UE in RRC_INACTIVE. The RNA can be defined as a list of individual cells, a single RAN Area ID, or a list of Tracking Area Codes (TACs). As long as the UE moves within its RNA, no signaling is generated.

Key Functions

• Defines boundary within which inactive UEs move without signaling
• Can be configured as cell list, RAN Area ID (RAI), or Tracking Area Codes
• Paging for inactive UEs is scoped across all cells belonging to the RNA
