38.3.1 Channel Activation
By means of the CHANNEL ACTIVATION procedure /
GSM:08.58:4.1/, the BSC orders the RBS to prepare a dedicated
channel resource for use, and to start reception and transmission on its
associated logical channels.
Supported channel combinations /GSM:05.02:6.4/:
•
(i) TCH/F + FACCH/F + SACCH/TF
•
(ii) TCH/H(0,1) + FACCH/H(0,1) + SACCH/TH(0,1)
•
(v) FCCH + SCH + BCCH + CCCH+ SDCCH/4[0..3] + SACCH/
C4[0..3]
•
(vii) SDCCH/8[0..7] + SACCH/C8[0..7]
Supported channel numbers /GSM:08.58:9.3.1/:
•
Bm + ACCHs (Associated Control Channels)
•
Lm + ACCHs
•
SDCCH/8 + ACCH
•
SDCCH/4 + ACCH
Supported activation types /GSM:08.58:9.3.3/:
•
Immediate Assign
•
Normal Assign
•

Optional element in /GSM:08.58/. The
element is required by the RBS to carry

A signal sent by the RBS to the MS which
the MS uses to advance its timings of
transmissions to the RBS to compensate
for propagation delay.
