RRLP:posCapabilityReq
by Andreas Schmidt-Dannert 18 Sep '10

18 Sep '10

Hello all, I am trying to get a Positioning Capability Response from a MS by sending an Positioning Capability Request. I checked ETSI TS 144 031 (v9.2.0) to figure out how to build the package. Only the "extended-reference" field is mandatory and so I tried to send a package just with the content of that field. The "extend-reference" consists of the smlc-code and the transactionID. By testing I found out that I have to send at least 6 octets. The first octet is as usual the referenceNumber and to specify the rrlp component. The last 2 bits of the 3rd octet and the first 4 bits of the 4th octet are for the smlc-code. The rest of the 4th octet, the full 5th octet and the first 6 bits of the 6th octet are for the transactionID. Furthermore the first 3 bits of the second octet are for the choice extension. Anyway I have no clue what the meaning is of the last 6 bits of the 2nd octet and the first 6 bits of the 3rd octet although it seems like that the 4th bit of the second octet is an extension bit. However if I send a package I always get "Meassage too short" error. Adding octets does not help. Anyone has ever got a Positioning Capability Response for a Request? If yes I would really appreciate if that someone would share this Request with me. Wireshark always shows me that I have sent a Positioning Capability Request but the Response never comes but the error message. RRLP is implemented in the phone since I get responses for a Measure Position Request. I think by now I have sent around 500 packages :) One example I am using is: 0x30 0x0E 0x00 0xFF 0xA2 0x04 Best, Andreas

Using two nanoBTS at the same time (as neighbor)
by Luca Bertoncello 18 Sep '10

18 Sep '10

Hi, list! I'm trying to configure OpenBSC to use two nanoBTS (DSC1800) as neighbor cells. What I'd like to have is, by the measurement report, to get the values of both cells. Can someone say me, how can I configure the two nanoBTS as neighbor? Thanks a lot! -- _______________________________________________________________________ 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

[PATCH] count sms delivery attempts
by Nico Golde 16 Sep '10

16 Sep '10

Hi, attached is a small patch to add sms delivery attempt counting using the db_sms_inc_deliver_attempts() that already existed. I was a bit unsure what exactly counts as a delivery attempt judging by GSM 04.11 but it made sense to me to count that with each CP-DATA. Cheers Nico

alternative hardware
by Hans Witvliet 15 Sep '10

Hi all, did anyone allready had the chance to have a look at the magicjack femtocell ? As far as i could see, it has limited capabilities, but at a price of about $200-250 it is tenfold cheaper than ip.access nano-bts. Currently they only speak of support on ms and apple. Even if it would allow a single connection through the guard-band channels, it would be enough for me. hw

> did anyone allready had the chance to have a look at the magicjack > femtocell ? hi, not really. the homepage www.magicjack.com shows something, but does not say anything about GSM or femtocell. products at ebay called "magicjack", look like a simple POTS interface for VOIP, not a BTS. but if someone knows where to get this femtocell, it please let us know. andreas

power amplifier for DCS 1800
by Konrad Meier 11 Sep '10

11 Sep '10

Hi, I am building a GSM Test-Network at the university of Freiburg (Germany). We have a license for some channels in the DCS1800 band. For the network we are using nanoBTS and we would like to amplify the TX Signal from the nanoBTS. Does anyone know a suitable power amplifier? The output signal from the amplifier should be 1 or 2 Watt? Regards Konrad
