IIUC you plan to add this in next steps?

TBH, I am not sure how the S1GW should behave in this case. It's not clear whether the `INITIAL CONTEXT SETUP FAILURE` from eNB indicates that all E-RABs requested in the `INITIAL CONTEXT SETUP REQUEST` are rejected implicitly, or does the eNB then send `E-RAB RELEASE INDICATION` explicitly? If the former, then it's a non-trivial task that would require us to maintain some additional FSMs.
