Installation of Openbts (RPM)

Openbts source code can be downloaded here: http://sourceforge.net/projects/openbts/

Openbts a variety of questions to get started here: Http://gnuradio.org/redmine/projects/gnuradio/wiki/OpenBTS

I was very excited to start touching gnuradio and then to Openbts+asterisk. At the same time also unprepared, after the introduction, who do not know what you want to build platform for what purpose, no way to give clear guidance, can only self-action.

Just intact openbts, I can't wait to run. As a result, you can run. However, take a look at the following alarm, which happened with the tragedy of Txtune failed with status 1. Later only to understand, is the use of hardware caused by different.

is in http://sourceforge.net/projects/openbts/, the hardware used in the Fordummies.pdf tutorial

The following figure is the hardware I used, a piece of board, Rx and TX separated. This is very different, so can not directly use openbts/release, to make changes, fortunately, this work has been completed. Can be directly used by others, OPENBTS/UHD version of the change.

Using the OPENBTS-UHD version, I still want to modify, such as, Ac_define (USE_UHD,1, DEFINE to 1 if using UHD), here would have been 1, changed to 0, because I do not use UHD.

If you haven't changed here, and you don't need UHD, you'll get the following error when you/configure. Do not underestimate this error, perhaps because of this error, the progress of the project will be postponed for a week.

Finally, there is a key point, do not use UHD, always have a driver. After the above steps are complete,./configure--WITH-USRP1 This USRP1 is the driver you want to use! When you get here, make installs, and it's not easy!

The installation is complete, the experience will be openbts fun. First of all, you want to get IMSI, after Openbts set up, I am here to take gsm.mcc=460 GSM. mnc=10, then, using the mobile phone to find operators, will find a named CHN-10 operator, choose to access it. Then, in Openbts, tmsis can get imsi.

What is MCC? MCC is mobile country codes,460 on behalf of China

What is an MNC? The MNC is mobile Network codes,10 is not used in China.

China's specific operators and networks such as:

This information can be found in the ITU.

Through Openbts, I learned that my imsi was 460029078808551. So I can send text messages to my mobile phone through Openbts.

The format is as follows: Sendsms <IMSI> < send SMS to the number displayed on the phone > (number can be arbitrary, but must have) MNC <text>

So the text is sent out.

This is the text message that I received, garbled the article, is I try to send Chinese information, the results found not supported. Some people may wonder, IMSI is not mobile phone number ah? IMSI is present in the SIM card, it is not a mobile phone number, nor is it the number behind the SIM card. The real mobile phone number is msisdn. GSM is the two separate areas, for a certain security, the real use will also assign a tmsi!

This way, the OPENBTS can be used normally. Two phone calls and send each other text messages, light has openbts still not, but also to asterisk (this later mention).

Then you install Wireshark and Wammu.

After the installation is complete, you can follow the Https://svn.berlin.ccc.de/projects/airprobe/wiki/tracelog tutorial, with Nokia3310 in-depth study GSM protocol!!!

Finally, we recommend two materials
