BSIC: Stands for Base Station Identity Code which is
transmitted on the SCH. It is expressed as:
NCC = National Color Code of PLMN. Numeric 0 – 7.
BCC = Base Station Color code. Numeric 0 – 7.
Each operator in a country is assigned one NCC value n to
ensure that the same NCC is not used in adjacent PLMNs. The
purpose of the BSIC is to distinguish between cells with the
same carrier frequency but from different clusters. It can also be
used to distinguish between cells from different operators at the
border between two countries. It is essential for the locating
algorithm that the correct neighboring cells are evaluated.
