BSIC is defined on a per cell basis and it
is sent on the logical synchronisation channel (SCH) on the BCCH frequency. GSM
03.03, Annex A, assigns one NCC value "n" to each European country
"to ensure that the same NCC is not used in the adjacent PLMNs". A second
operator in a given country
would use the NCC value "n+4". When an MS
reports the results of the measurements made on the serving cell and the
neighbouring cells,
The measured signal levels on the serving cell. The
measured levels, the BSIC and the BCCH frequency of the neighbouring cells

composed of two entities:
