Hi Rajesh, be carefully about TEMS measurement.
Sometimes could happen that the decoding BCCH/BSIC is not OK.
TEMS could measure BCCH=100 and BSIC=10, but in reality BSIC is defined BSIC=11.
MS has some time to measure and to decode all SYS info.
And if you have for example new site without definition in tems.cel, there will probably in the “Serving + Neighbors” window, cell with same BCCH+BSIC definition as you new site, but somewhere far a way.
