[PATCH] Print decimal MCC and MNC unless format is incorrect.
by ☎ 30 Oct '12

30 Oct '12

Hello. Right now MCC and MNC value in ./mobile app are printed as hex but without 0x - this is confusing and inconsistent. Attached patch fix that although I'm still puzzled why value printed by "show subscriber 1" looks like hex representation - see example below (with patch applied). Note that 0x385 == 901 and 0x046 == 70 I suspect misuse of gsm48_decode_lai()\gsm48_encode_lai() but unable to pinpoint location yet. show subscriber 1 Mobile Subscriber of MS '1': IMSI: 901701282457741 ICCID: 8901901702282374810 Service Provider Name: Magic SMS Service Center Address: 0015555 Status: U1_UPDATED IMSI detached LAI: MCC 385 MNC 046 LAC 0x03e8 (385, 046) Key: sequence 0 31 64 7e 4c e1 dc 48 00 Registered PLMN: MCC 385 MNC 046 (385, 046) Access barred cells: no Access classes: C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 List of preferred PLMNs: MCC |MNC -------+------- 901 |070 (901, 070) List of forbidden PLMNs: MCC |MNC |cause -------+-------+------- 106 |003 |#255 (106, 003) 106 |007 |#255 (106, 007) -- best regards, Max, http://fairwaves.ru

proof of concept bts
by Erich Dachleger 22 Oct '12

22 Oct '12

Hi list, Regarding the interesting video from Russia(Positive hacking days 2012) where Sylvain demonstrates av proof of concept bts, is it a dsp patch of the osmocombb firmware before one uploads to the c123 phones that one has to do? The tasks then are modified in this patch or also elsewhere? And then one removes and replaces a tranceiver-code in openbts sourcecode? [I have tried the tacooper version of osmo-bts but that that code-approach is for the sysmo-bts, althoug the osmocombb phone proof of concept bts is mentioned in the tacooper thesis online] Regards Erich

My point is, if you ask people to do things for you you need to give them a reason of why they should help you. E.g. if you have a survey you might say that a randomly selected participant will win a 25 Euro voucher from Amazon. Now I don't ask you to buy things from Anazon but to think about why people should help you. One of the reason (non monetary) is to create a "database" that will be available to the community. A good example is the "terminal-profile"[1] initiative started by Kevin. He created a script (forkable) to query the terminal profile, there are clear instructions how to use it and it automatically uploads the data to a database. The database is publicly accessible and the whole content can be downloaded. Do you notice the difference? With Kevin's approach the whole community will benefit, with your request only you will benefit. > > i'm newbie here, but i do try to contribut if i can, and will continune to do so. it is not fare to judge me like that! Well, time will tell and I am happy to correct myself in case you make any contribution (detailed bug report, work in the wiki, bug fixes in the source). cheers holger [1] https://terminal-profile.osmocom.org/

Well, your thesis can have a copyright as well (you could even decide to not publish it at all). You can also decide to publish the raw data you collect on the way. Given the fact that you didn't consider this means that you are more on the take side. > i'm a student in bremen. i just thought it will help me to gain some extra points. but i guess it's not a good idea to do so.

What is the license? How will you reward people that help you? How does this benefit the osmocomBB project? What is the name of your thesis? Where are you enrolled? Who is your advisor? holger

Help please！~ tracelog of different providers needed
by xuewenyao 21 Oct '12

21 Oct '12

Hi all, I try to study the GSM core network setups of different providers. Therefore, tracelog of gsm providers from different countries is needed. I’m seeking your help for sending me some tracelog with two actions: making a phone call (MO) and sending a sms (MO). It should take no more than 2,3 minintes. Please tell me the provider and the country when you are sending me the tracelog. Thanks,
