whats the difference between tch blocking and tch blocking?
that’s a very tricky question, let me think.
oh yes, there’s a green apple with a bright mind but a cheap car, hidden in the background of the picture.
OOPS!Sorry.i meant tch blocking and tch congestion.
blocking dives you the non served calls
congestion gives the time when no resource are available (it is possible that nobody needs them so no blocks)
there is a possiblity to have high blocking and low congestion – this means that you have a peak of the attempts.vanderley, this is highly dependent on the indicator formula. in alcatel for example, there is the TCH congestion rate (percentage of rejected TCH attempts / TCH requests), and the system congestion time.
there is no “blocking” per say.
What is the difference between TCH blocking and TCH congestion?
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.i can understand how complicated it must be for operators to work with 2 or 3 different vendors ! Each vendor has their own vocabulary…
How we can define mean holding time.
Erlang per tch seizures (usualy in seconds)
What is the difference between TCH blocking and TCH congestion?
Hi All,,
TCH COngestion Is No resources available for allacation for time “x”.
TCH Blocking is %age attempts made during TCH congestion.
Hoope it may Help..

What is the connection between TCH Blocking Rate and Call Setup Success Rate?
It is true if your Blocking Rate is high, your CSSR must be low?
Hello alll
is that mean the TCH congestion rate (No avaliable Resources “all the resources are busy ) and Blocking rate for another reason (is it assignment failure ??)
we need more explaination PLZ
could you give us an example .what does mean blocking , when it occures ??
thanks
ayat,
blocking rate and congestion rate are the same thing !
it means the subscriber requests for a channel, but the BSC rejects this requet because no more channel available.
it can happen at TCH assignment or SDCCH assignment.
