Abstract
Embodiments described in this disclosure address issues arising due to a current cell having incomplete information about the NR ARFCN for reference point A for all other cells which are included within Last Visited NG-RAN Cell Information. A source NG-RAN CU signals UE History Information to a target NG-RAN CU in a handover message by determining whether the UE History Information includes a previous Last Visited NG-RAN Cell Information entry indicating a Network Type, an NR ARFCN for reference point A, and Cell Type that match those of the current cell associated with the source NG-RAN CU; and adding to the UE History Information a new Last Visited NG-RAN Cell Information entry indicating for the current cell the Network Type, the NR ARFCN for reference point A and the Cell Type.
