An additional hint to Andreas: The appended patch is a simple hack which sets the subscriber number to be called for an Emgergency Call. I only quickly tested this a while ago, so I don't know if it will always work. And of course the fixed number used in the patch should be replaced by a number tacken from the Config or DB.

Emergency Call
by Andreas Schmidt-Dannert 04 Oct '10

Hello all, I would like to establish an emergency call with OpenBSC for testing reasons. I already set "rach emergency call allowed 1" but I get only a busy line. Is there something else I have to do? I guess the emergency call procedure is fully implemented in OpenBSC? I found some hints in the code but I am still not sure. Thanks, Andreas

Need help on Open BSC code.

Hi Guys, We are implementing the separate MSC module and we will be using the openBSC, and we are mainly concerned for SMS services. So, I will be highly obliged if you can provide us the documentation on openBSC code so that we can understand the messages expected on separate MSC side from open BSC and the messages to be sent from MSC to openBSC side. -- Thanks & Regards Tejas Oza

Dear sir, I am planning to buy a ip.access nano BTS to run at GSM900. What features should I quote as specification while placing the order ?? whether it (OpenBSC) will work properly with GSM900 or should I go for DCS1800 ???? Thanks.

ip.access beginner question
by Maggie Balsamic 21 Sep '10

21 Sep '10

Hi all, I've got a PCS 1900 version of the ip.access BTS that I'm trying to get working with openbsc. I'm able to connect to the ip.access using bsc_hack, but I'm not sure what my next step should be. I made basic changes to the included bsc_hack ip.access config file, but I'm guessing that I'm missing something basic. Not sure if this matters, but one oddity I've found as I follow the instructions on the wiki is that ipaccess_config did not properly set the primary-oml IP. However, I was able to get the debug telnet client working, and set the oml IP directly from the ip.access debug shell. What I'm looking for right now is what I need to do to get bsc_hack to show a phone attempting to authenticate, etc. I'm wondering if it could have something to do with the channel config at the end, since I don't know how to set that. I've included my current bsc_hack config and the debug logging from bsc_hack. Any help would be much appreciated! Thanks ========BSC_HACK OUTPUT: <0005> bsc_init.c:1123 WARNING: You are running an 'accept-all' network on a BTS that is not barred.

nanoBTS question
by Albert Paijmans 21 Sep '10

21 Sep '10

Hi, I have been looking around and I am wondering, when you are interested in a consumer 3G / Femto or Pico cell it might be very cheap through AT&T at around $150. Might somebody be working rverse engineering on those cheaper cells? The nanoBTS from ipaccess is costing euro 3450 Mind you this is without any software or server, just a single nanoBTS unit. Does anybody have any experience and info about pricing? I find this price crazy but it is the only way in the Netherland to buy it officially. Also I have a license for GSM frequencies ad for that price they only send it to an address. Thanks Albert

Picocell from HAY SYSTEMS
by Konrad Meier 20 Sep '10

Hello, Searching the web I found the following BTS: http://www.haysystems.com/mobile-networks/hsl-picocell/ The System seams to be very similar to the ip.access nanoBTS. POE and Abis over IP. Can someone roughly estimate the time needed to integrate this BTS into openBSC? The developer I have in mind already has some experience in OpenBSC. What exactly is needed to complete this task? The company also has a different BTS called Femtocell. The interesting thing is that they offer a "Femtocell Trial Package" for USD 7200. The trail Package include BSC Software and two BTS. I also has a Network Interface but I found nothing about the protocol used between BSC and BTS. Regards Konrad

RRLP:posCapabilityReq
by Andreas Schmidt-Dannert 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
