Also known as: BCC
Base Station Colour Code (BCC) is the code transmitted in the SB (Synchronisation Burst) of GSM systems. The BCC is used by the MS (Mobile Station) to distinguish between cells using the same frequencies, when the MS is deciding on which cell to select and to lock-on to.
The BCC is also important during the receiving of the BCCH (Broadcast Control Channel), to identify the TSC (Training Sequence Code) to be used
