Hi,
Actually, it was written in the title, but I didn’t notice it before… sorry.
Blocking drop refers to the MS or the MFS being in a frozen state. For example, the MFS is always sending the same DL RLC blocks, even if it was already ack by the MS, or the MS is always ACK the same DL RLC blocks, even though the MFS has sent new blocks.
In simpler words : the MS or the MFS are having some minor s/w issues, so they need to establish a new TBF (that will reset the connection)
