I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

[PATCH] sms: Rename gsm340_gen_oa() to gsm340_gen_address_field().

by Alexander Chemeris

An according change in the OpoenBSC is following. Since we're changing the external API we should probably increase a lib version as well. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

SMPP + OpenBSC

by Jesús Vega Diaz

Hi all; I have deployed one ipaccess nanoBTS 1800, with OpenBSC (osmo-nitb) and all the osmocom suite apps. I have already make succesfully GSM calls, SMS, and GPRS/EDGE packet data connections. I now want support for sending binary SMS, i have read that with SMPP i would can. I have compiled OpenBSC with SMPP but now I don´t know how to use it, i think it is in the OpenBSC vty, but i don´t know the commands or how to use the interface. If you can give me some light in this thread i will grant you. Sorry for my English Best Regards Jesús Vega Diaz

Possibility to use INET socket for external MNCC

by Luca Valtulina

Hi list, wouldn't be useful to have the possibility to choose (at least) between UNIX and INET socket to be used for connecting to an external MNCC? If this will be the case where should the choice be made? I was thinking to add an extra option to bsc_hack but the choice can also be hard-coded (prior to compilation). cheers luca

OsmoTRX on Parallella.

by Andrew Back

I wrote a blog post about running Osmocom on Parallella, with UmTRX: http://www.rs-online.com/designspark/electronics/eng/blog/building-a-gsm-ba… Just using the dual-core ARM in the Zynq, so nothing surprising/interesting to this list and it's more of just an intro. However, I'm curious as to opportunities for improving the performance by offloading parts of the transceiver to the Epiphany chip. Does anyone have any views on how practical this might be, effort involved and potential gains etc? Cheers, Andrew -- Andrew Back http://carrierdetect.com

[PATCH] oml: Pass all valid state change requests to the model

by Jacob Erlbeck

Currently ADM state change request that tries to set the administrative state to the current value are immediately ACK'ed. Beside the caching problem, this could lead the protocol inconsistencies if two such requests are sent one after the other and the second arrives before the procedure of the first has finished. This patch removes the shortcut in oml_rx_chg_adm_state() which immediately called oml_mo_statechg_ack(mo).

Fwd: OpenBSC and Roaming

by Sahil Gupta

Hi there, I'm fairly new to the mobile world and am still coming to terms with a whole new world of terminologies. The project is to test out a theory in my lab before wanting to scale this at a larger level for commercial purposes. The intent is to be able to have roaming available with a roaming aggregator in the United States with a small-scale mobile network enabled using OpenSource software. We are probably looking at implementing no more than 15 BTS's nationwide to attract roaming customers at high traffic locations. Our roaming aggregator would like us to send them MAP SS7 Messages from our MSC. My understanding of the requirements so far are: 1 x BTS (this could be a PC with some radio cards or something like a nanoBTS) 1 x MSC/BSC/VLR We won't be issuing any sim cards on our own network in the long run and hence I don't see the point in us having a unique HLR. Are there any gurus here that would be willing to share their intelligence? -- Thanks, Sahil -- Thanks, Sahil
