Description

When having a NITB with one GSM1800 BTS on ARFCN 877 and one on GSM850 on ARFCN 130 (that is not broadcasting), the Icon2 stick failed to join the network. When removing this cell (and hence the neighborcell information) it works immediately. The test was done with a nanoBTS.

Tests:

  • Make this stable, I had issued another AT+CFUN=0/CFUN=1 today morning and while I did this yesterday it is not a clear call
  • Test with sysmoBTS and the nanoBTS (e.g. maybe some SIs are not scheduled)
  • Look if all generated SIs are being sent
  • Look at the spec if such config is legal..
  • Look at the generated SIs
