Hello,
I want to use the local sims having different MNC/MCC for implementing GPRS
using osmocoms with OpenBTS same as I have used them for GSM calls and sms
using only openBTS. But your site
http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS says, "it is currently
not possible". As it is long when posted on this site so I want to ask is
it possible *now* to use the local sims? Hope you have understood my
question. Waiting for your reply. Thanks.
Regards,
Saba Arshad
Hello All,
We have executed profiling test of two versions of algorithm for decoding compressed bitmap of EPDAN.
>From the results , we see that performance is better in Tree based decoding (Version2 as given below )
Version 1: Bitmap based decoding as present in current master branch ( Function name osmo_t4_decode )
Version 2: Tree based decoding ( Function name decompress_crbb , as proposed in patch "Decompress the CRBB bitmap using tree based approach"<http://lists.osmocom.org/pipermail/osmocom-net-gprs/2016-March/000525.html> )
A sample bitmap taken from a real mobile log is used for the test.
Host execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -17 MAX -19 AVERAGE -17.9
Version 2 (tree based decoding): MIN -4 MAX -13 AVERAGE - 5.2
Target execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -277 MAX -583 AVERAGE - 353
Version 2 (tree based decoding): MIN -67 MAX -86 AVERAGE - 69.8

Hi,
it looks like after the rebase done by gerrit something didn't compile anymore. Could someone please have a look at https://gerrit.osmocom.org/#/c/429/ and fix the fall-out in master?
thank you

Hello Max,
> What about MCS UL? Do you have some statistics which one has been used
The uplink tests have been completed for all EGPRS coding scheme (MCS1 - 9) using the ping or TCP download.
We have not conducted specific test for throughput estimation in uplink direction till now.

Hi.
I've noticed that OpenGGSN is not part of
https://gerrit.osmocom.org/#/admin/projects/
Is there plan to move it to gerrit as well or shall I send patches to
this list instead?
