IE "endc-ReleaseandAdd-r15" false or true


What does IE “endc-ReleaseandAdd-r15” indicates?

What if the value is false and what if the value is true?

If set true:

nr-Config-r15 - this contains:
endc-ReleaseAndAdd-r15 - this indicates whether the existing EN-DC configuration should be released before the new configuration is added.

If the full NR configurations of the SCG shall be released, the nr-Config is set to release, whereas if a new NR configurations shall be included in the same message, the nr-Config is set to setup, and the endc-ReleaseAndAdd flag is set to true. Either way, the procedures will trigger the same UE behaviour, namely perform the EN-DC release specified in TS 38.331.
