thx for the details. It’s not clear though 🙂
MS camps on a neighbor: Can you see 837 in the SI msg n°5 or n°5bis/ter ?
When camping on a BCCH, the MS shall receive a SI msg that contains GSM900 neighbors, and another SI msg that contains DCS1800 neighbors (SI5 & SI5 bis or ter, i forgot)
do you see those 2 different SI msg ?
Let me know what happens after you recreate the cell. Check also that you allow multiband operation (by allowing the transmission of the second set of neighbor list), this should be a radio parameter.
