Description

If the SIG-BVC on the SGSN side for some reason is not completing the BVC-RESET procedure, we end up sending BVC-RESET for the PTP-BVC, triggered by the PTP BVC-RESET on the PCU side.

I'm not sure if
  • the PCU-side BVC-RESET shouldn't even complete if we don't manage to BVC-RESET the SGSN side, or
  • we should simply delay transmitting the PTP BVC-RESET until the SIG BVC-RESET happened on the SGSN side.

The latter seems more well-defined particularly in the situation with multiple SGSNs around.
