Section: A.34 Monitor of Secondary Node Addition for E-UTRA-NR Dual Connectivity
Content: In the E-UTRA-NR Dual Connectivity scenario, the Secondary Node Addition procedure is initiated by the MN and is used to establish a UE context at the SN to provide radio resources from the SN to the UE. The success or failure of Secondary Node Addition directly impacts the quality level for delivering the service by the networks, and also the feeling of the end user. So the success or failure of Secondary Node Addition needs be monitored, and for the scenarios that the path update is needed during the Secondary Node Addition procedure, the path update related measurements are also needed.
