MDT cell trace specification

do you know about specification MDT celltrace file for Ericsson? Now, I write parser for MDT trace. Huawei spec I found, but Ericsson - no.

About Huawei/Ericsson RAN 2G/3G/4G/5G.

Do they have MDT (Minimization of drivetest) solution?

I know that Nokia has a very good one.

Ericsson also has since 2019.

I see Huawei has a very good one. (Just checked HEDEX).

Yes, Huawei has a good one too.

Hi all, what is the format of MDT( Minimisation of Drive test) file of Huawei?

What extension does it has?
