Hi,

Pix you are right it depends how the vendor calls it.
But as far as I know:
Congestion = time when all resources are occupied (no free TCH available)
Blocking = rejected (blocked) attempts over all attempts in %.
Also there is different formulas for TCH blocking. For example in subscriber perceived TCH Blocking all successful directed retries to another cell are removed from the nominator.
