Operational Channels

Operational Channels

In each cell, there are four types of channels that take active part during a mobile
call. These are:
 Forward Voice Channel (FVC): This channel is used for the voice transmission
from the BS to the MS.
 Reverse Voice Channel (RVC): This is used for the voice transmission
from the MS to the BS.
 Forward Control Channel (FCC): Control channels are generally used
for controlling the activity of the call, i.e., they are used for setting up calls
and to divert the call to unused voice channels. Hence these are also called
setup channels. These channels transmit and receive call initiation and service
request messages. The FCC is used for control signaling purpose from the BS
to MS.
 Reverse Control Channel (RCC): This is used for the call control purpose
from the MS to the BS. Control channels are usually monitored by mobiles.
