Hi Pix,
Thanks for the quick reply. As I said the operator is not able to run the A-inteface traces at the time being…
As far as the SDCCH Radio conditions are concerned…everything is fine like BCCH plan, Idle Channel Interference…all find And you are right that changing TS or TRX can be helpful and I have already done that…As I said, it happens only in certain hours not for the whole day…depicting something beyond Radio…
Anyways…I would try to find something via Drive Test again…Meanwhile can you let me know about any common thing which has been recently obsreved regarding this problem as you are saying its happening in all brands..
Thanks
