Hi,

I have setup YateBTS on PC, with Ubuntu 16.04 and NI-USRP 2922. Unfortunately GPRS isn't working. Sometimes G signs appears showing GPRS is available but when i browse, it is gone. The logs are given below. Kindly tell me what can be cause of this issue and how to fix it?

The yate,log is here

While ggsn.log is this

Hi,

Please see this thread:

http://forum.yate.ro/index.php?topic=1381.0

Please post a log with the debug options specified there enabled.

The yate log shows a call and SMS being done. Keep in mind, that on 2G, CS services suspend Data services. In the GGSN log, you can actually see the GRPS suspension request.
