Hi Dieter,
Thanks for the test!
I will make research about this SYSTEM INFORMATION data related to paging
and see if it's possible to modify it every time.
If nothing possible I will try to deal with the 470ms period.
Can you tell me if the mobile will RACH at each paging request or if it can
miss some?
I already saw in OpenBSC that the paging request is sometimes send more than
once for a call so I am not sure. May be it could be something to fixe in
the code? Or the phone sometimes doesn't react as it should?
Normally the RACH is sent 3 time slots after the paging request right?
Thank you
Best regards,
Eric Cathelinaud

Yes I would like to make the cell phone answer as fast as possible but

RACH for each frame would be really nice. At
least one RACH out of 2
frames,
then i can have at least 1 RACH per 10 ms.
I don't think you have much influence on setting the paging reorganisation
mode, this is done by the BTS when it detects that something has changed
with paging (the BTS can detect it by looking for changes in the SYSTEM
INFORMATION messages). I did a quick test with a nanoBTS 1800, if for
example BS_PA_MFRMS is changed, the BTS will activate the paging
reorganisation mode while switching the parameter. I can confirm that
with the Nokia Network Monitor, it displays the page mode and indicates
"paging reorganisation" for a short amount of time (about one second).
You can try to constantly switch the SYSTEM INFORMATION data related to
paging, but I don't know if this will help with what you want to do.
Also please note that I have not tried it with the BS-11.
Best regard,
Dieter
