TEMS session error

[hengbong]

I am facing a strange behavior during TEMS sessions. During data session measurements, "session error" appears a lot.

Matching the output with traces, it appears that MS sends a "PDP Deactivate Request" with cause: regular deactivation. This occurs after attach, HTTP load..etc

Has anyone faced this before ?

It it mentioned in most of the message details of the session error message that the cause is either "Connection timeout" or "session aborted by user", I think the main reason is that the RAN disappeared suddenly leading to session drop.
