The GSM broadcast channels are used to provide information
to a mobile station about the network and timing information
required for synchronization. The GSM broadcast control channel carries general
cell-specific information, such as identifying the network operator and neighbouring
cells. The GSM frequency correction channel, which exists on the
downlink only, is used to transmit a frequency standard and
the location of the first time-slot of the time division
multiple access (TDMA) frame. The GSM synchronisation channel also exists
on the downlink only. Reception of a single synchronization channel
burst enables a mobile station to synchronise to a base
station.
