Hello,
In case of more BTS with the same provider (MCC, MNC) the MS camp on the strongest cell
But the information of the strongest cell are given (from the BCCH) to the MS, not only in order to make a cell selection and cell reselection C1 and C2 criterio are used.
C1= Received_Level_Average- RXLEVACCESSMIN - MAX(MS_TXPWR_MAX_CCH, POWEROFFSET-P) for CELL Selection
C2= C1+ CELL_RESELECT_OFFSET--TEMPORARY_OFFSET*H(PENALTY_TIME-T) for Cell Reselection
I Haven't found all of these parameters
