Description
With a real physical layer, the BTS detects when the MS is gone. After some time without valid uplink blocks on the SACCH, T200 expires N200+1 times and a related RLL error indication is sent on Abis to the BSC.
When using osmo-bts-virtual, we don't appear to have any such mechanism, leaving channels on the MSC/BSC/BTS open indefinitely even if the related MS is gone.
