Reply To: high TCH congestion at low traffic



Thank you for the QoS report, it is very helpful. You forgot the TCH mean duration time though… can you get this value for those 2 hours ?

In my opinion, this is an “artificial” issue, not a real problem. Either a counter problem, or a faulty software, somehow.

Maybe you should also check the TCH request for incoming HO and for call setup. You might measure TCH congestion due to incoming HO = 4%, while you’re having only 60 TCH requests for call setup.

Finally, in order to reduce the congestion, you could activate TCH QUEUING, and increase the timer T11. It might help…
