    Dear all,

    I would like to know the suitable value of T3101 in Alcatel and Ericsson.

    To optimize this timer will improve the SDCCH fail in our network?

    Thank you very much.

    Hello SM.

    In the Ericsson networks, the T3101 can indeed improve the SDCCH Assignment Failure. If you monitor the counter CESTIMMASS from the dbo_CELL_MAIN or dbo_CELL_MAIN_PEAK tables from the GRAN_seg1 server you will see that at least a 5% of the CCALLS correspond to the expiration of the T3101. The default value for Ericsson is 1,5 seconds. We found an improvement by moving it to 3 seconds.

    Of course, ideally would be to have a Protocol Analyzer and measure the average time for the timer and see if the actual value is correct!

    I think in Alcatel-Lucent is easy to set a new value. However in Ericsson, even a small restart is needed on a BSC level.

    Default value of T3101 in Alcatel can’t be that low 0.3s. Should be 3 sec.

    Have faced the issue of “Missing Immediate Assignment”, but there was no SD blocking blocking on cell + routing area has been updated without doing anything, not even changes the MS location. Could anyone share the reason or explain it?
