Device auto-registration
« on: August 24, 2016, 05:24:18 PM »
Hi, guys, thank you for the wonderful job u did on the yate-bts first.
I've setup my testbed and finally wanted to try it out. Am able to locate the TEST-PLMN network manually and register to it with SMS and calls to it.
But decided to go one step further and since i have some foreign SIMs laying around the office wanted to test auto-registration and be my own microoperator(i'm using 2-4 dBi antennae so range is rather miniscule).
The issue is that the phones do not want to register to the network despite setting the MCC/MNC to their home network values. All i'm getting in the console is :
<mbts:NOTE> RadioResource.cpp:242:AccessGrantResponder: RACH burst for unsupported service RA=108 (while RA=X differs often)

I have been asked what kind of SIMs i have and they are Ukrainian possibly 3G sims, am i under the false impression that they should be connecting to my BS without trying to authenticate it just based on the MCC/MNC?

Since i was rushing to finish the post, forgot many of the details.
Am running a bladerf-x40 with the builtin FPGA and firmware version 2.0.0 on usb3.
Yate and YateBTS are both SVN(or SVN 503 as suggested by a forum post, but that didn't change anything)

A more helpful log slice is :

As i see it, i get incoming bursts but don't do anything with them.

Hello,
I've already posted that in this post: please read

http://forum.yate.ro/index.php?topic=1211.msg4328#msg4328

anyway I succeeded in doing that, I can help you,
you need to do a snapshot of the spectrum downlink of your operator you are intended to activate.
Remember that, once the procedure is up and working this is illegal since some UE (user equipment) around you could connect to your fake operator!
Before I want to ask you: what os are you using? because FW2.0 usb 3 doesn't work for yate bts:  http://www.nuand.com/fx3.php, new VID/PID are not recognized to yatebts, what version are you using?
Bye
Andrea

Hey, Andrew, thank you for the response, will be messaging you. I'm using Yate from the SVN with ubuntu and it recognizes it fine. I will be messaging you privately for a further explanation.
