DAPS Handover:
Elementary Procedure:
XnAP protocol consists of Elementary Procedures (EPs). An XnAP Elementary Procedure is a unit of interaction between two NG-RAN nodes. An EP consists of an initiating message and possibly a response message. Two kinds of EPs are used:
-
Class 1: Elementary Procedures with response (success or failure),
-
Class 2: Elementary Procedures without response.
F1-terminating IAB-donor:
Immediate Handover:
Used in the context of Conditional Handover, to refer to a handover that is executed immediately after the UE receives the Handover Command.
