Section: Annex C (informative): I-RNTI Reference Profiles
Content: The I-RNTI provides the new NG-RAN node a reference to the UE context in the old NG-RAN node. How the new NG-RAN node is able to resolve the old NG-RAN ID from the I-RNTI is a matter of proper configuration in the old and new NG-RAN node. Table C-1 below provides some typical partitioning of a 40bit I-RNTI, assuming the following content: - UE specific reference: reference to the UE context within a logical NG-RAN node; - NG-RAN node address index: information to identify the NG-RAN node that has allocated the UE specific part; NOTE: RAT-specific information may be introduced in a later release, containing information to identify the RAT of the cell within which the UE was sent to RRC_INACTIVE. This version of the specification only supports intra-RAT mobility of UEs in RRC_INACTIVE. - PLMN-specific information: information supporting network sharing deployments, providing an index to the PLMN ID part of the Global NG-RAN node identifier.
