Handover Procedure

The AMF supports procedures to handover a UE from source NG-RAN to target NG-RAN.

  • Xn Handover—The AMF supports Xn handover, used to handover a UE from source NG-RAN to target NG-RAN using Xn when the AMF is unchanged.

  • N2 Handover—The AMF supports inter-AMF and intra-AMF N2 handovers. These can be triggered due to new radio conditions/load balancing, if there is no Xn connectivity between source and target NG-RAN or due to AMF change.
