alternative bts

by Hans Witvliet

Hi all, A thread on the asterisk mailing list re-triggerd my memory. Last november or so i asked if it might be possible to use a gsm/umts-dongle as a bts. afaicr the general consensus was that it was not possible because the proximity of TX and RX hardware. I have been discussing it with my colleges today and wonder where we were making the obvious thinking-mistake... 1) i know, that certainly at higher powers, the receiver becomes deaf in the vincinity of a (high powered) transmitter, due to cirtuit overload, but in our case we only needs a single miliwatt or even less.... 2) scanning for multiple devices/frequencies is not needed. [the idea is to connect to a single hand-held-device, that is only one meter away, and feed voice through an existing IP-connection] 3) if a dongle is not usable for above reasons as a BTS, why is that same dongle (more-or-less) capable as working as a handheld? Same problems should occur as such, not? http://wiki.e1550.mobi/doku.php If they can tap in the device for audio/sms-client, it should also be possible to do it the other way round, as a single-thread bts.... still puzzled, Hans

Help understanding used power

by Luca Bertoncello

Hi, list! I'm trying to understand how the options "nominal power" and "max_power_red" work... Last Friday I tried to place 4 BTS in a rectangle of about 100x20 meter and then I examined the measurement reports of a mobile. They are very very bad, and oft it cannot see a cell. Then I tried to change the value of "nominal power" (max_power_red did not changed) and retry to check the measurement reports. No changes... :( Now I'm here in my office with a spectrum analyzer and try to change these values, but what I see in the spectrum analyzer is always the same... I restart OpenBSC after any change, of course! Could you please help me to understand what these values mean and how can I boost the signal? Thanks a lot in advance for your help! -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 23 Fröbelstr. 57, 01159 Dresden Fax: 0351/41381 - 12 _______________________________________________________________________ Impressum: NETZING Solutions AG - Fröbelstraße 57 - 01159 Dresden Sitz der Gesellschaft Amtsgericht Dresden HRB 18926 Vorstand Dieter Schneider - Aufsichtsratsvorsitzender Volker Kanitz USt.Id DE211326547 Mail: netzing.ag(a)netzing.de

RTP-Proxy without MNCC-BuildIn no running

by meckel＠netzing.de

Hi List I want to use OpenBSC with Asterisk and LCR. After a lot of reading I found out that openbsc must start with the Paramters "-m" and "-P". But i got a lot error messages like: <0006> gsm_04_08.c:2960 receive message GSM_TCH_FRAME <0006> gsm_04_08.c:2992 TCH frame to lchan without RTP connection So i tried a lot and start only with -P and the RTP-Proxy started. But LCR and Asterisk sure not involved because the missing "-m". So i need "-m". It is a bug or a feature that "-P" will be ignored if I set "-m"? I´m sitting over the bsc code but until this moment I didnt found something so I hope somebody here can help. Ulrich Meckel

Problem with RTP-Proxy

by Luca Bertoncello

Hi, list! We are trying to connect OpenBSC and Asterisk together (through LCR), but we have many problems. We start OpenBSC with the parameters -P -m --debug=DRLL:DCC:DMM:DRR:DRSL:DMNCC:DMSC:DNM:DLCH:DMUX:DHO Now, if we try to call a mobile phone from another one, we get many errors: <0006> gsm_04_08.c:2960 receive message GSM_TCH_FRAME <0006> gsm_04_08.c:2992 TCH frame to lchan without RTP connection Now, if I understand what mncc_tx_to_cc does, I can just think, that the RTP-Proxy is NOT active, but a part of OpenBSC thinks that it IS active. Another interesting problem is, that, although we start OpenBSC to debug the CC, we do NOT get a message like: Setting up TCH map between ... (gsm_04_08.c line 1606) Could someone confirm me my idea? And, maybe, give me a suggestion to fix our problem? We use OpenBSC in the version 0.9.11.375-ca8f. Thanks a lot in advance for your help Luca Bertoncello -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 23 Fröbelstr. 57, 01159 Dresden Fax: 0351/41381 - 12 _______________________________________________________________________ Impressum: NETZING Solutions AG - Fröbelstraße 57 - 01159 Dresden Sitz der Gesellschaft Amtsgericht Dresden HRB 18926 Vorstand Dieter Schneider - Aufsichtsratsvorsitzender Volker Kanitz USt.Id DE211326547 Mail: netzing.ag(a)netzing.de
